Hi there,
perhaps you guys can help me
I use a onePlus 3T 128GB and directly after delivery I update the OS, install twrp, make a clean backup and then personalized the phone.
Runs quite good but yesterday I wanted to update the system to 4.0 Nougat...
So I downloaded the full installer, backuped the full current system via twrp and then flash and install the 4.0 version.
Yeah... doesn't work really good...
After the Pin and the code for the sim card, the OS ask for a third pin code but none of both works. And I never have another pin code since years...
Then I wipe the cache and system with twrp and restore the last backup. Doesn't work. It only boots to the onePlus Logo and then nothing happens.
Same for the first clean backup without any personalisation...
For now I have an great smartphone that doesn't work... yayy...
Anyone of you has an idea how can I get my running phone back – with all my data and apps?
Edit1: adb sideload doesn't work
Edit2: Full Installer installed >> reboot >> no OS installed
Thanks for all guys.
Oliver

The friend who gave me twrp recommend this to me.
But unfortunetly the full image here is just a update, too... so of course didn't work.
But at this moment I can't transfer any stuff to the internal storage because I have no possibility.
Only success is that the device manager lists the oneplus as "Android Bootloader Interface". But nothing for transfer works.

When wiping system before installing a full roms zip (not only an incremental update), I would expect a working, os containing partition - like on the oneplus one (did that many times on bacon). But I can confirm, it's not working on opt3; at least not with oos4. In this case I need to restore working systemmpartition (from twrp-3.0.3-0), and flash then the rom zip.
current status:
twrp 3.0.2
I wipe the system and the cache again.
Restore my backup from sunday before I start this odyssey.
Try to boot the restored system >> stacks during oneplus logo on screen
Flash and install the 4.0 Update Rom
Boot >> enter Pin >> enter Sim Code >> see my customize lockscreen and a pop-uped telegram message
Want to unlock >> ask for another Pin that isn't my Pin or Sim Code (use these two for years from phone to phone)
Also have a full installed onePlus3T (perhaps with Nougat 4.0) that I can't unlock because of an unknown pin.
:good:

Would you try the following: From twrp restore your very first backup (firmware, system and boot), don't leave twrp and wipe (reformat with f2fs) data (I'm talking of the entire userdata partition, not only "wiping data without wiping media"); flash the full oos4 zip (the one with 1.4GB); don't leave twrp, go to Advanced->copy logfile. Try to boot system.
If the system stiil refuses to boot up completly, get the logfile with adb via twrp and show us.
DO NOT try this, without usb-c otg cable and usb stick, because you are reformating your data partition. That's the reason I have not tried this: need to get an usb-c otg cable (BTW: recommendations on usb-c otg cables welcome, but OT: so PM).

the unbrick tool works 100 percent - i had to use it myself too.
if you see "Android Bootloader Interface" in your device manager you did something wrong.
in the thread for the unbrick tool it says "hold volume up button while connecting your op3t to your computer". unless you dont to it this way you will always see the Android Bootloader Interface instead of the unkown device - trust me.
turn off the phone, wait a few seconds, hold volume up key and plug it in. it will work at least it did for me

I gave my phone to my girlfriend, because I had to head to work. She wrote to me:
"Tryed it a couple of times now and then there was something like "QHUSB_BULK" showed up. But only for around 3 seconds, then i got the message "RELINK HS-USB QDLOADER 9008 (COM4) installed". Now the device-manager has this "RELINK..."-thing, but not at "unknown devices" but at "Connections (COM & LPT)". I tryed to go to point "Update Device Software", but all I get is "its already installed". When i go to details, it sais something about "\system32\DRIVERS\cmnxusber.sys".
After this i tryed to get the QHUSB_BULK back on the screen, but it seems like Windows7 is installing this DeviceSoftware every time when i reconnect the phone with "volume button while connecting the phone to the computer". I even tryed to deactivate/deinstall the DeviceSoftware, but its the same game every time i try it from the beginning.
Then i tryed the MsmDownloadTool, but hey.. no response. Guess i need to update the software first."
Shes now sitting in front of my PC and trying the steps. I'm out of ideas at the moment, do you have an idea what she is doing wrong or where the problem is now? (At least we are a step further now, haha!)
@nvertigo67
I can look up for this sort of cable when I'm back home. But i hope this unbrick tool will succeed.

Look for my comment in that thread, I had numerous issues with the driver. I don't know exactly how I got it to work, but try my steps to get the driver to show up as Qualcomm 9008.

Girlfriend here: Whoever said that having a break and eat something before going back to some PC problem was right xD
Ok, what i did now:
First i deactivated the automatic Windows-Update (not sure if there was the problem, but i had some problems with this automatically-Winstupid-Stuff... doesn't matter..).
Then i connected the op3t with the volume-up-trick to the computer and i got the "RELINK HS-USB QDLOADER 9008" back in the DeviceManager. Now i deinstalled the DeviceSoftware and like you said (maybe i was blind before...) there was a checkbox unlocked. I locked it (said something like "deleting DeviceSoftware from PC" or something like that) and clicked on "OK" to deinstall the DeviceSoftware.
I interrupted the "automatical installing drivers" in the Popup what shows at the right side of the task-line (i only got ~3-5 seconds until it was finished, so i had to do this step 2 times until i was fast enough^^). Windows said now that there was no success in downloading/installing the DeviceSoftware. Finally!
Next step (now i had enough time, because Windows didn't download/install anything) was right-click on the "QHUSB_BULK" and finally could install the downloaded drivers. DeviceManager now shows a "Qualcomm HS-USB QDLoader 9008 (COM3)" at "Connections (COM & LPT)".
I started the MsmDownloadTool aaaaand got Sahara-Error
Tryed another run with changed properties (compatibility mode (Win XP, SP3) and gave AdminRights). Now it shows me "Start Download Firehose Binary" and then returns to the "Sahara Communication Failed"-msg. Glad i found lyall29's post at page 6. Needed to make the whole thing 4 times until this error was gone >_<
When the download started, the op3t got a.. not sure, yellow? maybe lightgreen? LED-signal during the download is now running.
Until i wait:
Maybe the first mistake i also had was:
When pressing the power-button for 40 seconds, the op3t has to be turned off at the end. Then wait some seconds. Then push the volume-up for 10 seconds and then while still pushing the volume-button, connect the op3t with the computer to get the msg at DeviceManager.
Nvm, after the download finished, i got another popup sais "unknown device" and that Windows couldn't install the DeviceSoftware.
I did "Step 9: Disconnect phone from PC and boot into system." aaaaaaaaaaand.... it worked. Q,Q
Now all i need to do is trying to get the backup back until my boyfriend is home
But one question is still open:
When we tryed to load the backup, then the op3t said, that the backup is encrypted. But.. i'm pretty sure we didn't encrypt the phone-data. We also thing, that the problem why the backup didn't work correctly was, that the data was encrypted and so we couldn't gain access to it. We tryed this with his Win7-PC and my Linux-Laptop. Even with different USB-Ports (2.0 and 3.0).
I'm going to do a new backup now from the op3t, but what if the problem shows up again?
Someone got an idea if the MD5-Backup-Stuff should be encrypted or decrypted?
Besides that:
Thank you very much for the help!! I guess i wasnt that qualified with fixing phone-issues and i might did some very nooby failures... so really thank you for your patience

When you say load the backup, you mean a backup that you made in TWRP recovery, prior to bricking your phone?
My experience with the unbricking guide was that it in essence did a full wipe and reset (including the recovery partition). That would eliminate TWRP from your phone as well as any stored backups you had.
When I unbricked, I opted to just leave it stock as nougat was around the corner.
I also re-read your original post. I wouldn't have considered your phone "bricked" at that point.
I would bet that you could have booted the phone into TWRP.
You'll want to keep these things in mind too for future TWRP encryption issues (it's a known issue that most likely won't be fixed).
1) before you make a twrp backup, remove any figerprints/pins/passwords from your device, sometimes prevents issues for me
2)if you existing pins/passwords don't work try "default_password" that may work
3)if all else fails, boot into twrp, navigate to /data/system/ and down the list will be a few files to delete
- password.key
pattern.key
locksettings.db-wal
locksettings.db-shm
locksettings.db
4) the last step is always the first step for me, too many issues with twrp and encryption

u r doing something wrong.. please follow guide correctly
It works 100℅
Just out of curiosity, did you unlock the bootloader before you did everything? Also did you go into settings -->developer mode and turn on OEM unlock and USB debugging?
From my experience, try wiping everything through twrp --> install the firmware/backup --> and then try doing another wipe and reboot. Now I understand you might lose your root/SU after wiping, but perhaps this will at least boot into the system for you.
If all else fails, try using ODIN and flash your stock firmware http://downloads.oneplus.net/devices/oneplus-3t/
EDIT:
If you're having driver issues try this.
1. Go into device manager (as admin)
2. Double click the device that you're having trouble with
3. Click on "Details" tab
4. Under "Property" dropdown, choose "Hardware Ids"
5. When you select that you should see a bunch of values under there. Right click the first one and copy it.
Ex:\ I have an S7 phone so mine looks like "USB\VID_04E8&PID_6860&REV_0400&ADB"
6. Now the value you copied, try searching it in google. Or paste it on here for us to help you find drivers compatible with it. Usually you can find compatible drivers in google. Once you find them and download them, if you go back to that device and click "Update Driver" you can manually point to the extracted drivers. It will find the compatible *.inf file and install it for that device.
Hope this helps!

Hi all!
Made a really stupid mistake this morning: I was getting frustrated with Linneage 15.1 battery performance, so I tried flashing latest franco kernel (without reading that 15.1 doesn't like custom kernels; mistake #1).
No big deal right? I mean sure, I didn't make a back up first (Mistake #2) but it shouldn't matter because I can just go into twrp and factory reset and reflash everything.
So off I went to copy over the zips to my phone -- went ahead and wiped everything (mistake #3) and then opened up windows explorer to copy over the zips. Turned out my computer couldn't see my phone.
I tried mounting and unmounting and installing and uninstalling drivers. Moving over to my other computer (linux mint) messing around with adb sideloads, and lastly tried using OTG. Turned out my computer just couldn't register my phone at all with adb.
So then I switched to fastboot -- at the very least I should be able to reflash stock and then root and then install custom stuf, right? But I couldn't get my phone to even register on windows or linux with driver changes using fastboot!
I was pretty upset at this point (still am, admittedly).
In fastboot mode whenever I plug in my phone my computer doesn't even bat an eye, and my phone just says it's waiting for a data cable connection. Windows will register it after a while as a "code 43: Windows has stopped this device because it has reported problems" after a while but I still wasn't able to get the right drivers to register the device. Doesn't even show up in lsusb in linux.
Wondering now if maybe when the device was alive I forgot to enable adb debugging first or maybe it doesn't register because it was set to charge only in the usb mode setting. Is there a way to change those settings in recovery like through the terminal? I would love to hear any possible solutions, I've been googling and search xda all over the place so any insight would be really appreciated.
Fortunately I had an extra shamu (with a very cracked screen) left over that I switched to in the mean time, but I'd like to get my old phone back in working order if possible! Any help or insight is appreciated!

You even made more errors. You don't seem to read properly. Franco does only support shamu up to nougat.
- Did you install the latest USB drivers and latest platform tools (adb, fastboot ...)
- Did you boot you phone into bootloader when you tried to connect?
Yup! I installed drivers from Google when I downloaded the platform-tools. I put my phone in bootloader mode when using fastboot, and my phone never indicated 'USB transfer cable connected' it just said 'connect usb.' also fastboot just said waiting for devices when I tried doing a getvar all....
try it on another laptop, try a new usb cable...you seem to have done everything right
I've tried a bunch of different computers and cables... the weirdest thing is that it'll use the cable to charge just fine, but won't let me transfer anything by mtp (in recovery) or fastboot when in its bootloader :/ still get "connect usb data cable" even if the battery is charging

Could be the cable. But the USB port could also be the cause. The simplest solution could be that the port is just full of dust. In that case, cleaning will help.
"Good judgment comes from experience, and a lot of that comes from bad judgment." - Will Rogers
IF you still have access to TWRP, you can move your zips on an usb drive and connect it via otg and mount in TWRP and flash from the USB drive. Might help.
Hello,
Device is rooted and BL is unlocked and on FW v47.2.A.10.45
Performed a wipe incl system and internal storage. (Dalvik/ART is included)
Wanted to start over, and perform a full backup after this...
I shouldn't have checked ''internal storage'' in TWRP is my fault here i believe.. NO OS.
Now NEWSFLASHER can't flash the device cause of error:
No usb device with vid:0x0fce pid:0xb00b
Click to expand...
Click to collapse
Grabbed a other laptop.
Disabled driver signing.
Reinstalled GordonGate flash driver.
Also this laptop gives the same error.
Can i throw away this device ?
I still can get into flash and ''adb'' mode.
Things should be possible you should say.
Thanks in advance..
Fingers crossed, still busy ruling things out.
Does it show up correctly in device manager?
It did yes. (SOMC FLASH DEVICE)
Issue solved in the meantime.. but how ..
I've flashed this unit 3 times before now in flash-mode while the led was BLUE. (flash mode, as it should be right)
Apparently it can be flashed as well while it's in recovery mode.. (or bootloader mode?)
Connected the phone through USB (on pc) while holding volume DOWN when led went GREEN.
In NewsFlasher i pressed N twice, and it flashed instead of giving the above mentioned error.
Luckily i got quite fast in the meantime of repeating all the steps (flashing twrp, magisk, removing bloatware etc)
Issue solved.
Now full nandroid backup time to get this over with.
Thanks for your time anyway!
Saw different solutions for this everywhere, but not flashing a device while it was NOT in flash mode, lol.
Curious if somebody has an explanation for this.
I got EXACKTLY the same problem....
Worked fine last summer. :s
Hi! I have the same problem.
Please, can you explain to me exactly all the steps to fix it?
Thank you so much
This appears to occur if there is a problem with the "android-sdk-platform-tools" package..?
I have a OnePlus 8 Pro running Oxygen OS 11.0.4.4.IN11AA. Upon installing Magisk, I can no longer turn Wifi on. I have tried restarting, clearing the cache from recovery, resetting network settings, basically all the things the "wifi wont turn on help pls" guides say to do. Mobile data and bluetooth work absolutely fine, so what's going on?
Sound is also non-functional. Even after plugging in earphones (which worked with this phone previously) nothing comes out, and the phone doesn't even seem to recognize them. I also noticed that after a reboot the volume controls are set back to the defaults.
Additionally, the system is very slow to start up and the screen stays black until after the unlock prompt (which displays over the black screen) and then the wallpaper and everything else loads. (after which the device is responsive as normal)
These problems occurred even without installing any modules or otherwise modifying the device. I'm using the latest version of Magisk, 22.0 (22000).
I originally tried to make a GitHub issue, but it was closed by the bot since I didn't follow the template GitHub never showed me. Also, us non-canary users experience issues too. [mini-rant over]
Sorry if this is a duplicate, the search system appears to be malfunctioning since the updates.
The Fix!
Looks like I'm solving all my problems today. I had a hunch that the culprit was the boot.img which I downloaded--it was corrupt. So I went to OnePlus' site and downloaded the OTA package, extracted the boot.img from that, and flashed it through fastboot. When I rebooted, I was greeted with the beautiful almost old-IOS charging sound, and Wifi!! That boot was quite speedy too!
Hi could you explain how did you reboot your phone i have totally same problem...i tried msm download tool but i cant get my device to show there....could you please tell me how did you put OTA package into phone ? thx
FIXED!
in the end I was able to use MSM Download tool....i just had to manually download Qualcomm drivers so that my phone can be recognized. After that MSM worked and rebooted my phone totally clean. Gosh not gonna root for a while now XD
PS: More fun is that my Windows PC wasn't connected to internet so i had to download everything on my macbook and through USB stick I was bringing all app to Windows.....longest 6 hours of my life

From fastboot, use the volume keys to select Power Off and then press the power button once. Make sure the phone is unplugged while doing this. Then, with the MSM tool ready on your computer, hold down both buttons on your phone and plug in the cable from the phone to the computer. It should automatically boot into EDL mode, and MSM should say Connected.

When I had to do this I didn't connect the device to the network since I don't trust Windows 10 not to open a billion ports up and use my infrastructure for Microsoft's business. Copying to and from a crappy 2.0 drive sucks!
Hello everybody,
To explain things a bit better than just this title. I have a Mi 5 that was working smoothly for quite a long time. Had a modified MIUI ROM flashed on it with many specific apps such as xposed, Magisk and also TWRP. However, my GPS has turned completely dead for some months. Couldn't use it anymore. After some researches, I found out it could be software related. So I decided to flash a new ROM (AOSP Extended) to see if that could fix the GPS issue.
First I backed up the whole system via adb on my laptop and then wiped the whole system. It turns out after trying to flash the AOSP ROM, I came across a message saying I should have MIUI 8.1.30 or older. Or something like that... Can't remember exactly. Just read that I was supposed to update my ROM to a newer stock ROM to be able to flash AOSP in a second time. I did a lot of different operations and I can't remember them all but it turns out one moment, adb started to flash a ROM because the adb command line was saying it. But it failed. Aftert that moment, my phone definitely got bricked. I have no clue what exactly happened, it's kind of confused...
Currently, the phone is always displaying dark screen with mi logo and "unlocked" mention below. Power and volume up will just reboot it to the same state (meaning twrp is not longer installed or accessible). In this dark screen mode, plug the phone to a computer will do nothing, it's not even detected in devices manager. On the other side, power and volume down will boot the phone into fastboot mode, the computer beeps when I plug the USB cable and I can briefly see the Android device with a yellow warning in the dev manager. But after something like 20 seconds, fastboot mode goes off and phone restarts on black MIUI screen.
I've tried to install Google drivers, Qualcomm drivers and did numerous actions but the phone isn't detected anymore. Also, tried to type command "adb devices" in the short time when the phone is detected by computer in fastboot but it shows an empty list. I'm pretty desperate, seems I've tried anything and I've no ideas now... Just saw there is possibly a hardware fix which requires to dismount the back of the phone. Not sure what it does but I'll try it out if no other solution shows up...
Any idea is welcome ! Thanks
Well, looks like my thread wasn't so popular Finally found a workaround after nearly 8 hours searching for a fix. Thought that might help anybody else having the same struggle as mine. What I can tell is that it's not related to the computer used since I've made the same operations on 3 different computers, same problem for each of them. In fact, there were two problems :
First the bootloader not remaining more than 30 seconds. To stop this, I had to open the devices manager and as soon as the Android device would appear after turning it into Fastboot, I would right click on the visible device (appearing with an exclamation mark) and update manually the driver following the process that is described in many topics (locate the Google Android devices USB drivers that I downloaded right before). The time is quite short so you have to be pretty fast, otherwise, the MI 5 would disappear, forcing you to do the fastboot mode operation again. I have to say that doing it without the device being recognized is not working. So if you install with the legacy driver option, it's not going to be associated directly to the device. At least, not in my case.
Once I had done this, the Fastboot mode would remain on. I found my way pretty fast until that moment but the problem was adb wouldn't detect my device. Typing "adb devices" command would return no result, no matter what I did. Strangely, installing an old version of MiFlash (last ones gave me error) would help the computer to detect the device. I don't know why, possibly because the drivers are better ? Anyway, MiFlash helped me to access the phone and Flash a new ROM. Usually, I was just using adb and it would do the job but this time not.
Hope it can help !
