Give me an app that uses Camera2 API and I'll test it and let you know.
Also @bullet25 I can never sleep anyway so add me to this glorious list, if you'd be so kind

Oh, that's a shame. I was hoping it would support Camera2 being such a recently launched phone. Hopefully it would work with a simple build.prop edit like the Redmi Note 3 or the Moto X Style.

There's always other alternatives that use their own camera drivers rather than manufacturer-bundled ones. Open Camera for one is a very good app that does not depend on device bundled camera drivers. It is very feature-rich and can be a powerful camera app if used in the right hands. Open Camera might be able to do what you're looking to do:

Thought I would ask this in the right thread.
My Amazon subsidized R1 HD is rooted with systemless Xposed installed. I did take the OTA update last week. It had been working fine for two days. I powered the phone off and placed on the charger, at which point it keeps continuously attempting to boot, just flashing the White Blu screen every 4-5 seconds. No combination of button presses, or holding of power seems to be able to stop it, so can't power the phone down, or get into TWRP. Ideas? It does not have a SIM in it at the moment, or when this occurred if that might matter.
While I have rebooted the phone many times since rooting, this may have been the first time that I have completely powered it down since rooting and installing TWRP this weekend. I had not made any changes to anything for a day or so, and it had survived many reboots. The only thing I can think of is that I did freeze the Amazon Offers App in TiBu to see what would happen, however, not sure that is in anyway related since it is not even getting to a point in the startup where it would check.
Is there some kind of boot verification Power Up, that does not occur on reset, where the modified Boot image of SuperSU would be the issue?
The only response I can get from the phone is that if I hold Volume+ and Pwr, the phone takes a few more seconds between reboots.....

Is it booting into android at least? If it is you can try:
Code:
adb reboot recovery
then in twrp do a default wipe (data, cache, dalvik) then see if everything is fine afterwards.
If not, try just letting it do its thing until it dies then see if it acts normal.
Otherwise its probably a hardware issue and needs to be replaced.
I've shutdown and booted mine several times with the TWRP and Root installed so I don't think its that.

Thanks! Yeah, it is not booting anywhere other than the White Screen that say BLU, so I can't even get to adb or TWRP (If I could I could fix it). Letting it die is my only other thought....... I was using a Nexus charge block, and a 3rd party cable which has been sketchy in the past, so maybe related to that.
But as you say, it may be hardware related, as it does not even seem to be going far enough in boot process to load Fastboot, let alone OS.
I raised a replacement request with Amazon just in case.....
Question on Encryption.
I have root and TWRP working correctly. My work Outlook profile requires (and I want) device encryption. I select the option to encrypt, enter my pin, get the Android guy gear cut in half thing icon for about 30 seconds then just a black screen. I let it sit like this for over an hour and nothing changed, so I rebooted. Phone isn't encrypted. Tried it again and got the same result. Am I missing something obvious here? Can you not encrypt if you have unlocked or something? Thanks!

I know with other phones you can do encryption with an unlocked bootloader, I don't know about this one. Either something is wrong with the phone's encryption or I honestly don't know. I'll try encrypting mine when I get a chance.
@brockwitting Encryption seems to be working. You have to unroot first and have a pin/patteren/or password to unlock the device. After that go through the encrypt steps. My phone shows the Android cut in half logo for about 10 second then a black screen for about another 30. It then rebooted and was at just the wallpaper. I hard shutdown by holding the power button then rebooted again. After I got a pin unlock screen after inputting the pin I had to press the power button, this might be normal I've never actually used android encryption before, and the phone was working fine since.
Screenshot
You can reboot into recovery afterwards and reroot.

Sorry for the noobishness here, is there an easy way to temporarly Unroot without doing a full device restore to my pre-root state?

Open the SuperSU app, go to settings and there's an option for Full Unroot. Select that, reboot, then do the device encryption. After you verify its working okay reboot back into recovery and flash SuperSU again. TWRP will ask for your password, just enter your password/pin when it does.

So, just wanted to close the loop in the event anyone else runs into this. After 7 hours of rebooting every 3 seconds, the battery ran out. The phone then turned on just fine when I attempted to restart it.......... very odd, but all seems well.

Well spft is still an option. At the point of power off to power on there is a pause on Android that spft uses to inject a DA program of sorts (download assistant). So try to do a readback of the first like 5mb. The read back information dosent matter itbis the DA injection your looking for. If it works the on off cycle should stop. Then unplug and phone should be off

WARNING: This should be the VERY VERY VERY VERY (Am I clear enough about this?) LAST thing you do to try and fix a chromecast. This can possibly fry a chromecast for good, so know going into this that it may not work!
Because of this, Me, XDA, and all other users are NOT RESPONSIBLE for any damage, problems, or issues that may arise from using this method. By using this tutorial, you agree and understand the above warning.
So, I had a Chromecast that I got stuck in "backupsys" boot mode, where it would try to boot the backupsys partition. Issue is, it would not boot, and you can't force it to boot from jumpdrive while it is in "recovery" or "backupsys" mode.
Well after tearing the thing down and getting UART setup, I started messing around, and found a way to FORCE the device to read from USB, regardless to the bootmode.
How this works is during the boot process, you jump 2 select pins on the PCB by the CPU, which causes the device to have a block read error while reading the system flash. When this happens, the device falls back into USB read mode.
Because this causes a read interrupt, it "MAY" have unknown effects on the longevity of your device, so like I said before, this should be a LAST RESORT OPTION ONLY.
What You Need:
Chromecast with Rootable Bootloader
Paper Clip/Needle to jump some TINY pins
UART hooked up to your computer
Jump Drive with the Root Image & USB OTG Cable
Process:
Step 1: Tear down your device, and have it hooked up to UART on your computer.
Step 2: Have the USB OTG Cable and Jump Drive with the root image plugged into the chromecast. Do not have it plugged into power yet.
Step 3: On the top side of the chromecast (Not the side with the UART Pins), carefully remove the RF shield to reveal the WiFi Chip and CPU.

}
Step 4: Have putty open and connected to your UART COM port. Also have "reboot recovery" in your clipboard. (Copy that command so you can right-click in putty to send it quick)
Step 5: Now, prepare to jump pin #26 (shown in photo below, marked with red square on right side of CPU) when you plug in the chromecast to power it.
Step 6: Plug in the chromecast power, and watch the UART output. Once the Chromecast LED turns read, use the paper clip to short pin #26 and you should get the following outout:
Code:
sys_init start. boot_strap=0x00000080 (source=NAND), boot_state=0x0

scanning bus for devices... 2 USB Device(s) found
scanning bus for storage devices... 1 Storage Device(s) found
If you do not see "Booting from NAND failed, booting from USB....!", unplug the chromecast, and try again.
Step 7: The chromecast will now try and boot the Jump Drive image. During this, there will be a root shell hiding under all the output. You need to QUICKLY and repeatedly press Enter until you see "/ # " flash on the screen. Once you see that flash, QUICKLY press right-click so putty pastes your clipboard, and then press enter. If you do this fast enough, the kernel will run "reboot recovery" and restart.
Step 8: The device will now try to boot the normal recovery partition. This is fine, because even if it fails, the bootloader will detect this and reset the device to normal boot mode after a few power cycles. After a few power cycles, the chromecast should eventually show the following over UART:
Code:
sys_init start. boot_strap=0x00000080 (source=NAND), boot_state=0x0
PG868: leakage=208 vcore=10 sysctl=59

And congrats, the device is now back to Normal Boot Mode! You can now hold the power button during power on to properly flash the rooted image, and your device should be good to go!
DEVS: If you want to help make this easier, can you make a USB image that just boots the kernel and stops at command line? Would make this process easier.
FAQ:
Q: Why do I need this? I can just hold down the button to boot from a Jump Drive.
A: This is true, but if a Chromecast is in any other boot mode besides normal, then it will be unable to boot from USB. This is just how the bootloader is coded. (I submitted a patch to google regarding this, even though it would never help us out thanks to the updated locked bootloader).
Q: Will this allow be to Downgrade/Root my device?
A: Answer is Probably not, even though this is untested. This is because the bootloader is still loading from the device, so it will still probably check the USB Drives image for a valid signature.
Q: I tried this, but my device still won't boot.
A: Well then there is probably not much else you can do, besides looking for a fix yourself. Remember, its a $35 dollar device so it may just be best to buy a new one.

This reminds me of what people did for the xbox 360 with the dual nand chips, or what Adam Outler did with the galaxy camera. He had a switch that would choose whether to boot the default eMMC or a SD card.

In case anyone didn't pick on my meaning, it would be cool if we could use a switch to boot from USB or eMMC.

technically this may be possible, but I am not a developer but don't quote me. The fact that we can load a kernel off a jump drive though should mean we have the ability to load and run a system image off of a jump drive.
I just got a second chromecast and am awaiting my USB OTG power cable, I do plan to root this one and work on seeing if my idea is possible.

How did you get the remainder of the shield off? I got the covers off but I can't get the shield off.
EDIT: I got it. Another question: do you leave your chromecast "naked" or?

You should put the RF shields back on after you do this modification, as they prevent interference and issues. During the dissection of my device though, I fully removed the shields (including the sides), so I have no choice but to run that one naked, but it is sitting on the side as I have another rooted chromecast I use for day to day usage.

To be more clear, you should jump both pins at point 26. I am planning on re-doing this thread now that flashcast is out, and can make this a hell of a lot easier.
Have not used my chromecast since I bought it, prob early August. Used it the first day and put it back in the box. Decided to play with it again and root it. Problem is as soon as you plug it into the TV it starts to update (have/had wifi off just in case). So I assume it downloaded the update way back when I first used it. Not sure if this update patches the root exploit or not and I don't want to find out. Will this method get make out of "update mode"? Anything else I can try? You mentioned Flashcast any way to use it?
Thanks

First off, any official OTA for the chomecast will patch the root exploit, so if that update goes through you will be unable to root your chromecast.
As for this method working for you, if you follow the jumping method as stated in OP, then yes, this method would force your chromecast to boot from the USB Cable.
As for using flashcast, thanks to tchebb's help, if you just boot flashcast 1.1.1 on a jumpdrive, it will automatically delete the OTA from the device, and reset the boot mode back to normal. So the need to use UART is no longer required!

Is your device rootable? if it has taken any official google OTA yet, then the device will be unable to use or boot flashcast as google patched the root exploit.
Next time please try to keep questions to the relevant thread, thanks.

IIRC, in another thread it was stated that Flashcast made no changes to the Chromecast, it was just to setup the USB drive to flash the Chromcast and it was the Pwnedcast ROM that made the needed changes to prevent the OTA from taking place.
It's mentioned in this post:http://forum.xda-developers.com/showpost.php?p=46307051&postcount=124 or am I misunderstanding what you mean?

That is correct, flashcast makes no changes, but it DOES reset the boot mode of the device back to normal. this is done to ensure that no device gets stuck in recovery mode forever, as well as deletes /cache/ota.zip so if a official google OTA is on the device, it gets deleted.

Deleting /cache/ota.zip isn't considered a change? So, if ALL that is done to a 12072 build is to setup the Flashcast USB drive, it can't be updated by Google?

No, the device will still be able to update from google if flashcast is ran, flashcast just deletes any already downloaded OTA that has yet to be installed.
I had a heck of a dilemma this past week.
I have the N900A that I rooted using Kingo Root. No safestrap or new roms, just rooted. I obviously had the 'Custom' icon.
At day 20, my phone wouldn't charge any more or be recognized by USB. I tried everything. Factory reset, cleaned the port, cleaned the cables, new cables. Nothing helped. And it would have to be warranty exchanged through AT&T, but the warranty was voided because of root. I couldn't use Kingo to unroot, because the PC wouldn't recognize it.
I was able to find a workaround, using this:
http://forum.xda-developers.com/showthread.php?t=2559715
In fact, I really only used the third step. I didn't download or flash the rom. By some miracle, the PC would connect to the phone when it was in download mode. I used Odin to flash those four files, rebooted, and the custom icon was gone.
I'm hoping that this has removed all trace of root from the phone. The knox counter is still at zero.
I thought I would post this in case anyone else had a similar problem.

At day 20, my phone wouldn't charge any more or be recognized by USB. I tried everything. Factory reset, cleaned the port, cleaned the cables, new cables. Nothing helped. And it would have to be warranty exchanged through AT&T, but the warranty was voided because of root. I couldn't use Kingo to unroot, because the PC wouldn't recognize it.
I was able to find a workaround, using this:
http://rootzwiki.com/topic/110386-return-to-stock-mj5-works/
In fact, I really only used the third step. I didn't download or flash the rom. By some miracle, the PC would connect to the phone when it was in download mode. I used Odin to flash those four files, rebooted, and the custom icon was gone.
I'm hoping that this has removed all trace of root from the phone. The knox counter is still at zero.
I thought I would post this in case anyone else had a similar problem.

Ok so, only doing step 3 returns the device to complete stock? I would do all the steps, but I don't really understand all of them.

I believe the rest of the steps serve to load the MJ5 version ROM onto the device (in case you've installed a newer one or something). Since I already had the stock ROM, they proved unnecessary for me. I just used Odin to flash those 4 files and since the icon disappeared, I stopped there.

I'm on stock too, I want to do this because I'm having problems with the keyboard. The whole process is really confusing to me, do you think you can help me out?

I will try, but I am not an expert by any means. I tinker, but hopefully these other more experienced guys will chime in if I say something incorrect.
1. Download odin from here: http://www.firmware-files.com/download.php?id=1&token=QDXtLX5r3hLhxpTt604CYR6zP9twKSmr
2. Extract odin to a folder on your computer
3. Download these four files:
http://www.firmware-files.com/download.php?id=8&token=1QMc777QYjZgceInVMKs1HlcxAWv2wrU
http://www.firmware-files.com/download.php?id=7&token=6AfQkrv4S1mjr2oClQdwHp62lZpT8BK5

http://www.firmware-files.com/download.php?id=15&token=5CYaBqGOCoJSQMM6K7WECGlLDK4NYWTT
4. These four files will be zipped. You need to extract the zip files somewhere onto your computer. Each file should have a .tar.md5 extension once you extract them.
5. Power off your phone. Put it into download mode. To do this:
Power off your phone completely'
Hold down the home button, volume down button and power button all at the same time
When the screen comes on, let go of the buttons
It will give you a warning. Press the volume up button to proceed to download (odin) mode.
6. Run the Odin3 v3.09.exe application (that you extracted in step 2)
7. Now that odin is running and hopefully connected, you need to specify the four files that you extracted to be downloaded. You should end up with a screen that looks like this:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
8. Click start and let it run until it is finished. Once it is finished, hold down the power button to power off your phone then do the same to turn it back on. The custom icon should be gone.
First thing I do after rooting is Wanam and turn off the Custom - just in case something like this happens. If the phone later blows up, factory reset if possible and walk it in for an exchange. Then if, when it blows up, even Odin can't see it, there's still no lock on the screen.

Doesn't factory reset delete the Xposed framework?
With AT&T you can't do a walk-in exchange after 14 days - pretty scary to mail it in for exchange and risk a $650 charge when they discover you rooted it.
I had the icon turned off with Wanam, but it came back.

I could probably write an accounting program for an agency as large as the US government (or have fixed the health insurance site - doing something for half a century does pound some knowledge into even rock hard heads like mine), but when it comes to Android, I'm one of the learners, not one of the teachers. You know the answer to this question better than I do. I'd assume it does. I've made a lot of stupid assertions over the years, so ...
I downloaded a course that I may start reading one of these days, so I might yet learn enough to write a "Hello, World" app for Android. (Programmers know what I'm talking about - the difference between being able to develop a program and being able to code something to run in a particular environment - and the only internal environment I know in Android is where the battery and cards go.)

SSSSSSHHHHHHHH!!!!!!! You weren't supposed to tell them that. I hope they didn't read this thread, and I hope the very nice lady who gave me the phone I'm using now doesn't get into trouble. (I'm not talking about walking in and saying "I don't like this phone, may I have a different one, please?" I'm talking about walking in during the warranty period and saying "could you please make my phone work?" and being told that they'll have to give you another phone. The only thing I'd trade my N3s for is N3s with unlocked bootloaders. I just want to see something other than comets revolving around Samsung's name.)
I had the icon turned off with Wanam, but it came back.

Mine stayed off - for the 3 or 4 days that the hardware didn't die on me. Then ... well, maybe Samsung has a way to read melted silicon, or whatever it did to make itself electrically invisible, but I'm not going to worry about it.
Wanam will keep the icon hidden but once you factory reset the phone I believe it deletes the xposed framework and the icon comes back.
I could be wrong about that, but that is my understanding.
I don't think you'd ever fool the warranty department that way, unfortunately, which is why I used this method.

after doing just step 3 did you run a root check to see if that was gone? also what was the state of your phone after only doing step 3....meaning custom on dl mode and lock on boot screen....just wondering cause the files are so small to think that it would completely return to stock (like day 1)

No custom and no lock. I didn't run a root check, not even sure how.
The files are small because you're not flashing an entire ROM. My ROM was still stock.
I thought I should share my findings regarding the downgrade process.
It's a long tutorial, but I listed every step for newbies too.
Biggest issue I had with it - is that the phone constantly downloaded the LL update, no matter what. So here is the solution:
I have used my phone with this setup for the past few days, and it did not download the LL update.
Now I can use my phone on trip, during work, and only lose a few %. Back with LL I lost all my battery even with a few hours of use.
The battery life is pure GODLY now.
Downgrading does NOT trip Knox!
Preparation...
- Download ODIN 3.09 and the latest KitKat firmware for your variant from Sammobile.com.
- Uncompress the firmware file.
- Do a full backup of your phone and your SD card files by copying over everything to your PC and by using Super Backup app. No promo, I just used this one and it works wonderful. (For Contacts, SMS, etc.)
Install phase ONE...
- Power off your phone.
- Enter Recovery Menu, by holding VOLUME_UP + HOME + POWER.
Once you see the Samsung logo, release Power, keep holding the other two.
An Android mascot will pop up.
- Navigate with volume keys, and power. (power is "ok", volumes are up and down.)
- Go into "Wipe Data", wipe.
- Press reboot, then turn off your device once it boots.
Install phase TWO...
- Remove your back cover, remove SD card (just in case), remove SIM card.
- Keep battery, of course (lol).
- Boot phone in DOWNLOAD mode by holding VOLUME_DOWN + HOME + POWER.
- Connect your phone to PC, launch ODIN, load the unpacked firmware with the "AP" button.
Do not touch other buttons and switches.
- Press "Start", wait until your phone reboots.
Install phase THREE...
- After your phone booted, DO NOT CONNECT TO WIFI or INSTALL YOUR SIM CARD.
- Turn off wifi, make sure it DOES NOT CONNECT and DID NOT CONNECT TO ANY WIFI NETWORK!!!
- Go into Settings -> About Phone -> Software Updates. Untick "check for updates".
- Turn off your phone.
- Add a DATA SIM CARD. That can connect to mobile networks.
- Boot phone.
- Once it is booted, you will see that the phone will check for updates.. (yeah, to hell with our settings)*
- Open the notification, and you can find an option "NEVER REMIND ME".
* If it does not check, you can do it manually BUT ONLY IF YOU HAVE A DATA SIM CARD INSTALLED!
Then you can see what update you have, and whether you want to download it. Some people reported there are patches for KitKat on some regions.
DONE. You just outsmarted the evil Samsung. Good job.
- If you have your sd card installed, everything in place, you can now connect to wifi.
- Install/recover stuff, set up things, etc. You are good to go.
Ps.: If you are a Samsung employee, please, don't screw us over by force shipping some sneaky OTA to our devices. We do like to have choice what / which version we run, etc. Forcing crap down our throats is not really a nice way to treat customers.

Very well explained. I will keep this in mind if Lollipop doesn't start to get any better in the next update... ARG SAMMY WHY DID YOU DO THIS!
good write up. In addition, in your "Install phase THREE..." go to settings>applications manager> disable the "software update". - the one with green icon... this will stop the phone from upgrading to LP.. and you can skip the last part of your tutorial.....

I tried this one, but the update still showed up.
The only way was for me, is to tap on that "never remind me again" thing.
Oh well, if you had luck this way, that's fine too (at least we have a workaround handy if the original tutorial does not work for someone.)
Ps.: I hope the 5.1. update will fix all the issues (especially battery wise).
Though... the S6 5.1 update was a let down.
Perfect tutorial man for those beginners. But I thought you might want to add in one thing. When you originally flash KK there will be a small 100+MB update that needs to be done. As it was said in the XDA TV video its for a battery issue. Once that downloads and reboots to install, go right back into the Settings->About Phone->Software updates and uncheck auto updates.
Well. I was really tired when I read your reply and I could not remember if I ever updated adter the flash. Turns out I did, and now I have L coming down once again. Oh my.
Did a Nova backup, Super Backup, and I will reflash on the weekend. And now I will have to charge my power bank, and prepare a mobile charging cable too. Oh good times...

Sorry about that, I know the feeling, I did that a few weeks ago myself. Hoping there was a 5.1.1 update, But turns out I couldn't dismiss the update once it checked.
Guys 'coming stupid question'
If I want to downgrade ti kk do I nedd zo check or unchek re-partition? And what about Bootloader?
Thanks..My lolipop have too much lags and battery drop too fast...

I just do a factory reset in L, then keep the stock options on ODIN. That worked for me.

Ok, so since I had to reinstall the phone, I tried what you said.
Well, I only get the L update, after it checks for updates... No small update or anything.
I used this firmware: http://www.sammobile.com/firmwares/download/44754/N910CXXU1BOC3_N910COXX1BOC1_XEH/
N910CXXU1ANK5_N910COXX1ANK2_N910CXXU1ANK5_HOME.tar.md5
Maybe some regions do have small patches for battery issues (even on Kitkat)... or some regions don't have this "latest KK" as md5 file.
Could be the difference in versions your right.I used this one to go back to 4.4.4. It's the AOA1 build for my carrier

Yes, I have read the Sprint forum (I was searching for something else on Google), and some people did complain about that.
It's the bootloader or something.
Well, I am pretty sure it's possible to downgrade... somehow.
(The S4 Mini got the same problem. Once you are on 4.4, you cannot downgrade, it will just fail at the end of the process.
For God knows what reason.)
Uhm... make a thread in the Sprint forum, and if someone got his Knox tripped, he can try the reformat and other options to flash the KitKat rom back. (Well, even if he succeeds, we won't know whether those checkboxes will trip knox or not. There is just no way to tell. Knox should _not_ be tripped when flashing official firmwares.)

Please dont make another thread in the Sprint forum pertaining to downgrading to KK after being on OE1 bootloader and up.
Theres too many already and its been answered numerous times when OE1 first came out. I replied to your Question in the other thread about going to KK from LP and with you being on OF5, as of right now, its not possible and Odin will prevent you from bricking your phone, giving you an auth error.
hi my friend, i am in 5.0.1 lollipop with DBT Firmware CSC N910FXXU1BOC3. It is save to downgrade without trip Knox counter? Can you tell me the kitkat version who download?
I did this to my Note Edge too....LP is garbage and people praise it? I guess newer is not better...great tutorial though. Its people like you that take the time and do things like this that makes the world a little better place.
I'm only getting a NAND write start /fail error message. My phone has been doing some goofy stuff lately. Screen locks up (blank) and nothing responds. I get the menu lights for a sec and then they are gone. Plug the phone into the pc leave it for a few minutes and everything comes back. Dunno if that is a software or hardware issue.
Hi again,
it's impossible to downgrade to 4.4.4 from 5.1.1 AFAIK (in N910C)
thanks sammy for your locked bootloaders...

How to Bootloader Unlock (Part 1 of 2):
1. You will need a USB A to USB A cable (Example here)
2. You will need fastboot drivers on your PC
3. Unplug your clock
4. Plug the USB A to A cable into your computer and clock
5. Hold the volume + button and plug in the power cord
6. Keep holding volume + for about 20-30 seconds (It is slow to boot to fastboot)
7. On your computer in a terminal run, fastboot flashing unlock
Part 1 of unlocking is now done
AVB/DM-Verity Unlock (Part 2 of 2)
Unlocking the bootloader really does not give a lot to us because all the partitions are still being verified and the device will not boot if they don't match. Normally doing this on an Android Things device is not possible due to their Private key unlock system. But due to a leak, the private key for the Lenovo Smart Clock is available. Word of warning doing this causes the stock android things not to boot only the factory firmware located on Slot A will boot. Consistently if you don't AVB unlock the factory firmware on Slot A doesn't boot If you have already set up your device once the factory firmware is deleted and currently there is not a way to get it back (Hopefully will change soon).
If you are coming from part 1 you can start right away, if not you need to reboot to fastboot again.
1. Extract the downloaded AVB Unlock zip
2. Run this command in terminal
Code:
at_auth_unlock.exe cube_unlock_credentials_v2.zip
3. Wait till it finishes
4. Keep in mind the stock system does not boot properly with AVB off (It is weird some UI elements work but the boot animation never goes away)
5. To relock AVB in the future run the following command:
Code:
fastboot oem at-lock-vboot!

You can also unlock the boot loader simply with what's below... device does boot with this btw
fastboot flashing unlock
Although I've been messing with the device quite a bit. Plug in a usb keyboard, and you can get a web browser to recognize it and go to websites and such using the touch screen as a cursor, but you can't download APK files and install them and such. I've NEVER had the device recognized by ADB, so I can't pass commands from there either.

Just doing step one does not actually get you anything because if you flash something that isn't stock on the verified partitions it will not boot until you flash back the stock one. I have gotten adb to show up but not properly so it is offline. Still hacking away at it trying to get it to go so i can more easily debug TWRP and make edits to the system.

Ahhhhh got it. I couldn't find anything when I was messing with it like you've found with those commands. I'm kinda new to all this myself at something with nearly zero support, although I have a ton of experience with phones. Had to find my own exploit with my HTC One M7 because the version of android on the phone was the final supported update when I got it, and everyone said "nothing is possible with this android version" as far as rooting... so I figured out my own way lol
I'll continue trying myself though for sure
I also own one of these clocks, so if anyone has anything that I could test out, please share!
I think I'm bit late to party. Anyone who has a backup for those lenovo products, maybe it's a good idea to torrent them.

That's not really what I mean... I was referring to some interesting documents from lenovo. Have a few of those hardware but unfortunately didn't grab those files. Anyone also interested in these can PM me maybe we can do something about it.
when will twrp be avable
Interesting as there has a been a few of these turn up to auction of late .
I have gone with the 10' for main room and 8' for bedroom.. love them..
Got the oldies the little 7'
Great for streaming too..
The one I wish it did was announce the time by voice when the internet was down and we said "Hey Google". I am blind without my glasses and often when I am in bed, the internet is down in my area for maintenance period. The clock becomes useless when the internet goes down.
How are people getting the web browser to appear? I'm able to unlock the bootloader but can not boot with the AVB unlocked (well...technically it boots but still shows the spinning circle even though it will let you go to settings). I tried flashing the stock fastboot img and booting with avb unlocked and still get spinning circle. Not trying to get too fancy with this...just want to be able to point to a status page that I can leave it on.
Does anyone try to build a new firmware image and install this instead of stock?
Maybe compiling Android Things from source is possible, but looks like Google has stopped the development. The Lenovo Smart Frame seems to have the same MT8167S and runs on Android 10. Maybe it's possible to compile a LineageOS version?
lenovo.com/us/en/coming-soon/Lenovo-CD-3L501/p/ZZISZSDCD04
Another option might be fuchsia that contains a mt8167s board ref.
fuchsia.googlesource.com/fuchsia/+/master/boards/mt8167s_ref.gni
Googles Coral announced a Dev Board Mini based on MT8167s, maybe they port the Debian-based Mendel Linux to it.

Another option might be fuchsia that contains a mt8167s board ref.

Googles Coral announced a Dev Board Mini based on MT8167s, maybe they port the Debian-based Mendel Linux to it.

I suppose the smart frame is running android things as well. Compiling android things does make much sense except to prove the drivers are sort of working, this is not designed to let users have fun (ie installing apps).
Google *really* loves mt8167s for some reason. I'd say there's a good chance of we having full android on it but everyone's busy.
They are throwing these things at our head now. 35/40 USD during black fridays.
I don't think you can order the components for that price
Anybody still working on it ? Lenovo claims it's still working on the sound bug - hxxps :// forums.lenovo.com/t5/Lenovo-Smart-Display-Lenovo-Smart-Clock-with-Google-Assistant/Smart-clock-alarm-volume-too-loud-at-first/m-p/5040962?page=4 (latest reply 2020-13-11 from Lenovo) and they did some unanounced pretty good updates in september 2020 - hxxps :// 9to5google.com/2020/09/21/lenovo-smart-clock-night-light/
They also claim the source is on their website hxxps :// smartsupport.lenovo.com/us/en/products/smart/smart-home/smart-clock/za4r/downloads/ds539701
So is this dead ?

How to Bootloader Unlock (Part 1 of 2):
1. You will need a USB A to USB A cable (Example here)
2. You will need fastboot drivers on your PC
3. Unplug your clock
4. Plug the USB A to A cable into your computer and clock
5. Hold the volume + button and plug in the power cord
6. Keep holding volume + for about 20-30 seconds (It is slow to boot to fastboot)
7. On your computer in a terminal run, fastboot flashing unlock
Part 1 of unlocking is now done
AVB/DM-Verity Unlock (Part 2 of 2)
Unlocking the bootloader really does not give a lot to us because all the partitions are still being verified and the device will not boot if they don't match. Normally doing this on an Android Things device is not possible due to their Private key unlock system. But due to a leak, the private key for the Lenovo Smart Clock is available. Word of warning doing this causes the stock android things not to boot only the factory firmware located on Slot A will boot. Consistently if you don't AVB unlock the factory firmware on Slot A doesn't boot If you have already set up your device once the factory firmware is deleted and currently there is not a way to get it back (Hopefully will change soon).
If you are coming from part 1 you can start right away, if not you need to reboot to fastboot again.
1. Extract the downloaded AVB Unlock zip
2. Run this command in terminal
Code:
at_auth_unlock.exe cube_unlock_credentials_v2.zip
3. Wait till it finishes
4. Keep in mind the stock system does not boot properly with AVB off (It is weird some UI elements work but the boot animation never goes away)
5. To relock AVB in the future run the following command:
Code:
fastboot oem at-lock-vboot!
Locale changer instructions:
Coming soon (Need to figure it out)

We do not have the AVB unlock files for the smart displays sadly.
To start this journal I will begin by stating, I am not actually sure if it will be possible to finish this journal; from what I have read there can be quite a number of obstacles with international versions of the OPPO, some of which can be quite troublesome, but I thought it would be an interesting and hopefully helpful (for my self and anyone else wanting to do the same) way of going through the process with such a modern device.
The device arrives tomorrow, I wanted to get the initial post in without knowing precise details about the device.
I will update this primary post with the journal entries and post into the main thread when I update it going forwards
-- Entry 1 29/01/2022 00:21 (Dellivery today at some point!)
So far I have found out that cpw means car phone warehouse, which used(still is?) a store in the uk, 'EE' a network provider in the UK releases of the Oppo x3 find pro are apparently identical to releases from this store.
I have asked the user who informed me of this if they could possible put any information they are aware of within this thread.
Also, I will be doing the unboxing and initial looking at what it is via youtube I hope this is ok? I could not see a way to embed video onto this platform!
-- Entry 2 29/01/2022 10:53 (Delivery)
This is just a few images of the arrived device, simply unboxed and put on charge nothing has been set on the device what so ever.

Also note that this image showing the build number is by @alvydas it is not from my device yet! just some more information to add to the journal, this is believed to be the same as mine should show later on when I decide to video/start the phone up
Also for note the CPH (Possible related to CarPhoneWarehouse) prefix in the build number)
-- Entry 3 29/01/2022 13:11 (Turning on, Bootloader unlock, USB Debugging enabled)
Youtube video:
- May still be processing the HD version in google HQ!
-- Entry 4 30/01/2022 10:53 (Getting sorted)
Ok so we can't root it and we can't change the boot laoder .... however we can get novo launcher to start by default! The pro version at least!
Not exactly an amazing feat but hey its progress, I also removed the gmail mail application as I preffer outlook (mainly because I have 3 email accounts):
And boy .... you can really remove everything including:
130|OP4F57L1:/ $ pm uninstall --user 0 com.oppo.launcher
The coloros launcher its self X_X, so it seems you cannot get root, but there is no protected package, you can remove ANYTHING.
so this bodes the question .... other than wanting lineage OS of course, how thin can we get it ....
-- Entry 3 10/02/2022 10:53 (Hackery and cleaning)
.... So there is no fastboot on the international model, it is simply not there I even got EE them self to confirm this.
However, I have made some progress in discovering a way to get to the qualcomm flashable download mode, that is it will show up as a:
One of those (if you have the Qualcomm drivers installed), some information I put in the forum about this mode was this:
1) Turn the phone off (shutdown)
2) Hold the power button and the Vol up/down (I Forget which) down all the way through the phone starting, you will feel a little Bzzzzz
3) you will be presented with a menu probably in chinese, this is because you held down the power button and it auto selected the first language (its not a biggie), just press the back touch screen button in the top left <--
4) Select english (or chinese if you preffer!)
5) you will be presented with a menu that has 3 options, Format, Reboot, .... something else ...
6) Select none of the options! look to the bottom of the screen you will see a version mine was v12 o3 v1.2 - double tap this
7) you will get a warning you are entering 'customer service mode', and wallah .... you will get the device show up in device manager.
I was going to shoot a video of this, I still might! but its rather redundant at this point as I am now at a brick wall, I need to figure out how to deal with this mode, can I flash something to it .... how?
I am scrubbing the phone of all the bloatware I can and to be honest I have it pretty damn clean .... but still the fastmode is elusive and what else could be loaded onto this lovely phone.
Entry 1 added - nothing really important
Entry 2 added, initial unboxing simply for charging, video to come soon: looking for details!
The CPW in the build number is more of a guess than anything else we all could be wrong

Yh that's fine
Entry 3 uploaded, many thanks @alvydasd2 We do have slightly different builds it seems!
So now next up I believe its rooting the phone should be fun, also I beleive there is a way to root a phone but hide it from applications like paypal ... would love to find more out on this
Also have to figure out if all the fancy camera things will work with a custom rom, such as the microscope mode and all the advanced functionalities
Maybe the best initial tangent is to simply root the phone and remove any bloatware as well as installing novolauncher, followed by re-rooting it
That way I will not lose the ability to use the special camera functions and in turn still receive updates, I believe I can actually freeze certain packages too so they are effectively immutable, so they show up but can never run or be changed ... hmmm

Rooting ain't gonna be easy on this phone that's if you can unlock the bootloader which is pretty much impossible unless you have a Chinese variant of the phone or somehow figure out a way to root it without unlocking the bootloader would be a miracle

Check the youtube video, I appear to have lol ... though I did notice that going into the recovery menu is all in chinese ... so I assume its the chinese version:
The only problem being ... I have no idea idea what this menu says -_-
I guess that is tomorrows episode though, connecting it via ADB+TWRP
Usually first thing when you open recovery is choosing a language idk why English wasn't there and btw the difference between the builds is you're running lower firmware so if you try to update it you should get the same build number as me and if u had the Chinese version your model would have been PEEM00 or something like that

The OEM Bootloader though is saying its unlocked in dev options

Oppo has a weird bootloader cuz it can only be unlocked with an app that only works on Chinese version and to access fastboot u need a unlocked bootloader
just read this .... so there is no way to even fastboot the device https://forum.xda-developers.com/t/...access-for-oppo-phones-starting-2016.3348114/
I wonder if you could flash on the chinese version of the firmware
it seems that the device is really a 'realme gt 5g' .... trying to verify this
