yes its pure stock. you need to unlock bootloader .. and when return you need to relock it.
here are the commands for locking and relocking, and placing twrp temporary root it and then you are all set.
i use this method
go to where it says
Bootloader OEM Unlock + Root:
http://forum.xda-developers.com/tmobile-g4/development/stock-h811-20i-images-kdz-flashable-t3308227
I was able to Lock the bootloader.
1. I connected the phone to my PC
2. Powered on the Phone (it took a few tried of pulling the battery and powering on)
3. Check the box for OEM Unlock in Dev. Option
4. Use Minimal ADB and Fastboot and type in
Quote:
adb devicecs
- you should see the phone listed as one of the devices in the command line window
Quote:
adb reboot bootloader
- phone should reboot and you shouold see 3 lines of text on top
Quote:
fastboot oem lock
- nothing will happen on the phone, but on in the commandline it should say that it is done
Quote:
fastboot reboot
Phone reboots and the boot screen does not show the unlocked bootloader message anymore

Going to try right now...actually better wait til after work tommorrow. Need it for alarm and tv time.. Just in case something happens.

It wants me to downgrade and stuff. Is it possible to do it without downgrading? Also seems as alot of other posts say once your 20q you do not revert back to anything lower than 20o.. thats my concern.
Managed to get it unlocked.. Using that post.. Did not do the root part... So now.. Whats the next step? Install Recovery im sure. Then ROM... The plot thickens.

no dont downgrade i just used that post as reference the steps you need to use.. antirollback V3 (20o-20p-20q) (20i 10n this are V2.
yes install recovery use the same guide there..
use this recovery
https://dl.twrp.me/h811/
and rename it to twrp.img so the command should be renamed to twrp.img
have it on sd card. and hwen it boot you to twrp do install, then semlect botom right IMAGE and find the location the twrp is and select it and flash it , it will ask in a window select revocery .. and you are done with twrp installed permanent.

[Experiment] Avoid the 2.3.3 Bootloader

Just a suggestion and I'm not sure of the long term implications of this, but I was thinking those who want to avoid the hassles of getting the new bootloader that prevents fastboot boot and flash on locked bootloaders could try the following.
Unzip the update patch file to a folder on your computer.
Delete the bootloader.img file.
Use a text editor to open the file called /META-INF/com/google/android/updater-script and edit out/delete the following lines at the very end of the file:
Code:
ui_print("Writing bootloader...");
assert(package_extract_file("bootloader.img", "/tmp/bootloader.img"),
write_raw_image("/tmp/bootloader.img", "bootloader"),
delete("/tmp/bootloader.img"));
Rezip the folder with the altered files in it.
Boot to clockwork recovery and apply the update zip file with CW (since it's now not signed properly and stock won't do it.
We've had success with this type of modification to the update patch file from Google with people who modded /system files (like replacing gmail or the market app) that got failed updates on 2.3.1 and 2.3.2 updates.
I'm a bit pressed for time, but I may try this myself this weekend. I'm not in a big rush to update yet, though. I'm waiting for things like my custom kernel to become 2.3.3 friendly.
I've made a zip file that has the two changes I suggested above if anyone's brave enough to try it: http://dl.dropbox.com/u/432767/NoBo...9e.signed-soju-GRI40-from-GRH78C.98f3836c.zip
Bit late to the party i'm afraid, allready updated and flashed 2.3.3 update zip. I have lost my root and do not want to "fasboot oem unlock" yet...
My bad for being impatient as normal ^^
I will hold any actions and watch what solutions arise if any. Nice to see some methods being worked on

Could you not flash back to stock using Odin and then apply the bootloaderless update after? Just an idea . . .
Is there any risk of bricking? If not I don't mind trying it.

But we're not messing with the bootloader per se, we're preventing the update script from checking it and reflashing/updating it.
Still, there's always the risk of bricking as you say.
Slightly off topic, buy why go to all the trouble when fastboot oem unlock is painless and 100% reversible? Why intentionally hobble along on a gimped locked bootloader?

Because why not try? I'm not being sarcastic, ironic, facetious or anything rude, seriously; Why not? We have a phone that in terms of recent devices has an unprecedented amount of freedom in terms of rooting and unlocking of the device, why not push that to the limit and see just what can be done. Also, lets be honest, having your SD card wiped by the
Code:
fastboot oem unlock
command is kind of sucky. Sure you can copy all of your files to your computer then copy them all back but that isn't a short process and its boring as hell.
EDIT: @distortedloop: You know I trust you man, my point with my earlier comment is that running an outdated bootloader could very easily lead to an unbootable device, moreso than flashing a custom ROM so I was just being as honest and blunt as I could be
I updated the bootloader using:
fastboot flash bootloader bootloader.img
The bootloader stayed unlocked.

You can replace the new bootloader in the update with the old bootloader, here's a link for the old bootloader Bootloader_I9020XXJK1

if you have clockwork mod use this as a restore and you will have a rooted 2.3.3 its the easiest way to do it.
http://www.mediafire.com/?c1ww7zb837uycbk
just unzip and put the backup folder in your clockworkmod recovery folder boot into recovery and restore 2.3.3 takes 2 minutes and you will boot up with a rooted 2.3.3
also kept my bootloader unlocked. and i can flash back to any of my roms with no hassle keeping everything in tact.

No worries on the outdated bootloader....that's why I said "I don't know the long term implications of this."

But that defeats the whole point of not wanting to lose and restore your data, since the nandroid will write over all your stuff...
It also doesn't help those who end up with a locked bootloader and no root, since they can't access clockwork.
When I did it I kept my root and unlocked bootloader. If people didn't rush to update than they would have kept everything. I was able to restore my apps and all when I updated to the rooted 2.3.3

Will relocking bootloader wipe the phone?
I did "fastboot oem unlock" and everything is erased (it's not big deal as I always backup data).

[Q] Nexus 6 LOCKED - TWRP installed, and running??

I attempted to flash and unroot my Nexus 6 via Wugfresh's tool, and thought it was a success. I hit 'relock' and now the device is bootloader locked with no OS installed.
However, I can connect via fastboot so far, but I am not very good with it. I think I may also be able to push files, but when I attempted to flash SlimLP the device just reset.
TWRP is still present on the device, but I cannot unlock my bootloader without getting a ROM on there... So I am stuck...
I need to mail this phone back in tomorrow for cracked screen, so I am hoping someone can help me. Thank you.

First check here... http://forum.xda-developers.com/nexus-6/general/how-to-nexus-6-one-beginners-guide-t2948481
Get the sdk tools and once set up, see if you can do adb devices and have the phone show up on the PC, if so, do adb push (name of rom file) then boot to twrp and install. If that doesn't work, check the same page above (since you don't have an OS not sure what would happen) try the unlock instructions for fastboot ( I would wait for someone else to comment before trying this). You might want to message this user http://forum.xda-developers.com/member.php?u=2872010 rootSU and see if he can give guidance, he has lots of experience.
Locked Bootloader
I still can't seem to get past the fact that my bootloader is locked...
Thanks though.

Hey, thanks for the tip.
The link you sent was dead, and can you help me understand the commands for flashing in ADB with a locked bootloader?

Sorry my bad, here it is http://forum.xda-developers.com/nexus-6/development/fxz-nexus-6-recovery-flashable-fastboot-t3066052.
Follow the instructions as i posted, place the download rom in the /android-sdk/platform-tools/ folder and boot in bootloader and select recovery, select adb sideload there and type in cmd: adb sideload name.zip.
Unlocked Bootloader
The thread says they are for unlocked bootloader only.
I have TWRP installed, but for some reason at one point my bootloader was relocked.
So now I have No OS to 'enable oem unlock' to unlock my bootloader.
This is my issue.

I don't understand, what do you mean it worked for other users? The thread specifically states the bootloader has to be unlocked, and unfortunately I do not have an unlocked bootloader.
So I cannot fix this issue unless I either get a rom to flash with a locked bootloader, or somehow force unlock the bootloader

Relock Droid Turbo Bootloader

What's the process for going about it? I did do a search, but didn't find anything useful. Any help would be appreciated.
Reasoning: I'm going to be upgrading and turning in the phone, so it's time to put it back to factory.

1. Go back to stock everything by following section 0 of this guide: http://forum.xda-developers.com/droid-turbo/general/guide-how-to-unlock-bootloader-install-t3292684
2. While in bootloader mode, use the fastboot command "fastboot oem lock"
If you're turning in the phone to Verizon, this method is okay. However, don't do this if you plan on selling the phone to someone else. If they were to try and unlock the phone again, they would most likely brick it.
According to jcase relocking the bootloader it still shows a modified status code. Your warranty is permanently voided.
Are you on an Edge plan? Otherwise I don't know why you would be returning the phone to upgrade. Also not sure what their rules are on permanently modifying the software of one of these essentially "lease-to-own" devices, so might want to check the terms and conditions if this applies to you. If you are just trading it in for credit toward a new phone, I'd just sell it yourself unlocked and get a lot more for it.

A bootloader unlocked, rooted XT1254 would be more valuable to a buyer than one locked down. You've already done all the hard work.

Heya so I'm in a serious bind.
I skipped your step 1 and locked my bootloader. I have an unlocked bootloader. I recently upgraded through the normal verizon pushed update the marshmallow update. Anyhow. I now want to return the phone for an upgrade and well... I locked the bootloader. Then turn the phone off and turned it back on and it now says locked, but it says failed to validate system image. I then got freaked out and downloaded all the step 1 files and tried to flash the stock rom (which i already had installed!) and that doesn't seem to work. Did I brick my phone? Is there any way to get it working now that it is locked with any kind of android at all?
You're probably fine @droidfun1. You just need to use the marshmallow firmware package instead of the lollipop one. Get it here: https://forum.xda-developers.com/dr...-official-stock-firmware-6-0-1-mcg24-t3531571
Yup, I tried flashing the stock 6.0.1 rom with fastboot on my mac but I got all kinds of fails.
I found a mac compatible command line version of RSDLite and it totally worked! Not sure why fastboot couldn't successfully flash the same stock rom?
Now I just need to remove the bootloader unlocked warning (my phone is now locked status 2), but not sure if I can now that it is locked.

Strange. As far as I understand it, RSDlite just automates fastboot, so even if you're using RSDlite, you're actually using fastboot. Whatever works though.
As for the unlocked bootloader message, see my response to that post you made.

Need help to unlock bootloader

Man, I've really done research until my eyes are ready to pop out lol. Can someone please help me.
I'm using this guide to try and unlock my bootloader: https://www.youtube.com/watch?v=cfpehEkhfyg
Problem is, it's for a verizon version, mine's a note 4 T-mobile sm-n910t3
I'm just a noob and never had to do this unlock bootloader crap on my note 2. I need help.
I just want to unlock the bootloader, and flash recovery, supersu, and a cool rom like res. remix or CM remix.
On the video, the part I'm stuck on is he's using a file: "samsung_unlock_n4-2" with no file extension (.xxx)
I'm assuming this is a bootloader file?? I found a bootloader for my version which is a folder with contents:
FOLDER: BL_N910T3_DOK2 CONTENTS: aboot.mbn / NON-HLOS.bin / rpn.mbn / sbl1.mbn / sdi.mbn / tz.mbn
He goes on to use a CMD and fastboot to temporarily root the phone to install TWRP recovery,
but when he pushes this command: "adb push samsung_unlock_n4-fix /data/local/tmp/"
I don't think I can do that with a folder and I don't know which file to use.
QUESTION:
-DOES ANYONE KNOW WHICH FILE I NEED
-OR-
IS THERE A BETTER WAY TO FLASH A CUSTOM KERNEL THAT UNLOCKS THE BOOTLOADER, THEN ROOT, FLASH ROM AND EVERYTHING A LOT EASIER.
Side note, I didn't know I had to unlock FRP and tried to flash recovery. I also tried CFautoroot.
Both are blocked from working so I'm just assuming the bootloader is locked, otherwise it would say "mode developer" on the stock recovery. Off topic, I started reading about CyanogenMod Installer.... wtf ever happened with this program?!?!?! It sounds awesome!! It said it even would unlock bootloaders and everything. It was only after reading that it was put out of service that I stopped doing my happy dance. why in the fudge brownie cheesecake would you delete something so awesome? Anyway, can you guys plesaea help before I commit android suicide. That would be great.
I CAN'T BOOT INTO CUSTOM RECOVERY. IF I COULD DO THAT I COULD DO ANYTHING. UGGGGG
Anything, whatever...
I'm at a loss here......
It's been days and I'm frustrated.
910T3 versions are locked down for good after 6.0.1MM update but you could DO2 it and then just be stuck without wireless and NFC. Lol, its just so dumb isnt it lol. Pretty soon in the future maybe they'll jusf give us an option to have our devices custom made by your own specs??

Both are blocked from working so I'm just assuming the bootloader is locked, otherwise it would say "mode developer" on the stock recovery. Off topic, I started reading about CyanogenMod Installer.... wtf ever happened with this program?!?!?! It sounds awesome!! It said it even would unlock bootloaders and everything. It was only after reading that it was put out of service that I stopped doing my happy dance. why in the fudge brownie cheesecake would you delete something so awesome? Anyway, can you guys plesaea help before I commit android suicide. That would be great.
I CAN'T BOOT INTO CUSTOM RECOVERY. IF I COULD DO THAT I COULD DO ANYTHING. UGGGGG
Anything, whatever...
I'm at a loss here......
It's been days and I'm frustrated.

So far i know is N910T3 bootloader is not locked unlike verizon or at&t .
All you have to do is go to settings/about device and hit on build number 7 times .
You will see in settings "developer options" go to OEM UNLOCK and just turn it on this will unlock your bootloader and make sure reactivation lock is turned off in settings/security.
Thats it now you can go to download mode and flash twrp recovery and flash any rom from twrp compatible for your model.

Did this work, as in actually unlocking the bootloader right then, just by checking that box? I thought that option only got the phone ready for unlocking or something like that. I'm trying to root a T3 and don't want to flash over an unlocked bootloader, of course.

Has anyone tried this? I have an 910T3 running a custom ROM on lollipop 5.1.1. I wish to try and upgrade to marshmallow 6.0.1, and eventually a new custom ROM, but I am hesitant to do so as I have read that the 910T3 cannot be downgraded, should I like to return back to lollipop.
After setting OEM unlock , don't you need to use a procedure with adb fastboot through a terminal interface to unlock the bootloader?
I would love to know more about this before I attempt and irreversible upgrade.
Any help or advice would be greatly appreciated.

Once you upgrade to marshmallow you cannot downgrade to lollipop forget it.
To unlock bootloader you just have to turn on oem unlock thats it no need adb.
If you are already running custom rom as you mentioned your bootloader should be already unlocked.

So, trying to clarify, what you are saying is once you upgrade to marshmallow bootloader is permanently locked? From what I understand, locked bootloaders are what prevent you from changing ROMs, so I assume you are saying that OEM unlock will not work under marshmallow?
So no way I could reflash DOK2 Bootloader and return to Lollipop again? Or just flash a stock Lollipop ROM with ODIN?

Oem unlock will work no problem on marshmallow and you can root & flash roms easily same as lollipop.
But you can only flash marshmallow roms once you upgrade.
I was saying only you cannot downgrade from marshmallow to lollipop.
odin will fail if you try to downgrade

Thanks for the reply. In doing more searching around I found one of your older posts from 2016 and it sounds to me like it is a idiosyncrasy of the 910t3. I believe you stated you sold the T3 and ended up getting a 910T for that reason, so you could downgrade if you wished. Looks like I will be sticking with lollipop, unless I get another motherboard or phone. Thanks again for the response.

Unlocking bootloader: definitive bye-bye to automatic updates?

With the Moto Z, after I returned the phone to stock (flashed stock firmware and locked the bootloader), I'd be able to flash stock firmware with the flashing locked.
Not so with the Motorola One Zoom. In other words, flashing stock and re-locking didn't return the phone to its pristine state. Even when flashing stock firmware over stock firmware, I have to unlock the bootloader.
Differences I observed: on the bootloader screen, when re-locked the Z would show "oem_locked" again. On the One Zoom, it shows "flashing_locked" instead. I'm pretty sure it showed "oem_locked" before unlocking.
WIth the Z, every time I wanted to unlock the bootloader, I had to issue "fastboot oem unlock" followed by the unlock code. The code isn't necessary with the re-locked One Zoom.
In other words, maybe it was a one-way trip. It seems that the phone won't return to its original state, it looks it's modified for good. And I'm afraid this means bye-bye to automatic updates.
Am I missing something here?
My bootloader is also unlocked and I dont have any problems with receiving and installing OTAs I also have Magisk and EdExposed installed - no problems at all.

Phew! I'm glad I'll be able to install OTAs. Have you tried flashing it manually or via RSD Lite? Here it won't flash.

yes.
What instruction did you use to unlock the bootloader?
What region is your device manufactured for?
Does your PC see your device connected to the fastboot mod?
What does this command give you:
Code:
fastboot devices
If the device is detected, enter the command:
Code:
fastboot getvar all
And copy the result here.

Hey all,
I have the Moto One Zoom running on Android 9.
Also, It's Rooted with Magisk and have Riru EdXposed installed, can I install my OTA updates without bootloop or do I have to Uninstall Magisk, relock bootloader and factory reset/flash stock firmware to get latest OTA updates?
Any feedback is appreciated.
Thanks
