Hello, I am trying to recover my phone but I ran into several problems.
- When using TWRP 2.8.6.0 to install any ROM I keep getting an error ("This package supports bootloader(s): 0x4882, 0x4883, 0x4886; this device has bootloader 0x4807"). So my question on this: Where to download one of these and how to install them with the terminal of TWRP (I would like to use fastboot but ran in another problem)?
- When launching fastboot trying to flash a bootloader (where I'm not sure of it's the right version) it wont find my device [XT1068], I tried to solve it but nothing worked.
I hope someone could help me with at least one of the problems.
I think you are in kk ROM/bootloader and want to install a lollipop ROM.
Lollipop doesn't work on 4.4 bootloader (How to update your bootloader
Run fastboot with administrative privilege
I unlocked my bootloader, installed twrp and several roms to try them out, then decided to go back to stock. Currently have OOS 3.5.4 installed with stock recovery (that came with the toolkit). However, whenever I try to lock the booltloader again, the phone won't boot up. It will bootloop, or just stay off with the led glowing white. I tried to sideload the stock ROM from OnePlus, but it fails after about 45% completion. I tried both 3.5.3 and 3.5.4 and both fail after about 45%. The only way to get the phone to boot again is by unlocking the bootloader again, then it boots just fine. Tried unlocking with the toolkit as well as fastboot oem lock. Both give me the prompt on the phone, then wipe the phone and go into the bootloop.
Any suggestions on how to re-lock the bootloader? I want to be able to get the OTA update, which I think will fail with an unlocked bootloader. Note, I have also tried loading the Nougat update from settings - system update - local upgade (both full and update) and they also fail to load shortly after booting to recovery.
Thanks,
TR
Instead of using the toolkit, try just doing it manually.
fastboot oem lock IS the correct way to lock the bootloader.
If you're running into all those issues, try to reflash the stock rom from the official site. OR try this
NOTE: This WILL wipe everything on your phone so make a backup first!
First Unlock booloader1. On your phone go into Developer screen (Settings --> Developer Options)
If you don't have this go back to Settings --> About Device. Tap "Build number" 7-10 times to unlok developer options
2. In Developer Options turn on "USB Debugging" and "OEM Unlock"
3. Open ADB in command prompt and go to the directory where ADB is.
Type adb reboot bootloader
4. Once your device is in fastboot mode, type in fastboot devices to make sure your device is listed
5. Type in fastboot oem unlock to unlock your device bootloader
You can check to make sure it was properly unlocked by typing in fastboot oem device-info.
6. Reboot into your system
Files we need7. Download the following files:
TWRP - https://build.nethunter.com/test-builds/twrp/oneplus/twrp-3.0.2-0-oneplus3t.img
No-verity-opt-encrypt - https://build.nethunter.com/android-tools/no-verity-opt-encrypt/no-verity-opt-encrypt-5.0.zip
Magisk - http://tiny.cc/latestmagisk
Phh-Superuser - https://forum.xda-developers.com/attachment.php?attachmentid=3988488&d=1483407725
Latest Stable Nougat Rom - http://otafsc.h2os.com/patch/amazon...s3TOxygen_28_OTA_035_all_1612310259_2dc0c.zip
8. Copy all the files to your phone (keep the original on your pc just in case)
9. Load back up to fastboot mode
In ADB type adb reboot bootloader
10. Flash twrp img we downloaded above by typing
fastboot flash recovery twrp-3.0.2-0-oneplus3t.img
11. After this reboot into the system
Install all of our downloaded files through TWRP12. Now boot into recovery by issuing the following ADB command
adb reboot recovery (you should go into TWRP)
13. Once you're in twrp flash the "no-verity-opt-encrypt-5.0.zip" file OR you can format the data partition to f2fs to prevent the dm-verity error.
14. Now install the stock stable nougat rom we downloaded above
15. Do a factory system wipe / cache & dalvik
16. Install magisk through TWRP
17. Wipe cache/dalvik
18. Install phh SuperUser
19. Now reboot into the system normally.
NOTE: This *COULD* take a while since you did a clean install of nougat so just be patient and you should be good to go after this.
Thanks for the reply.
I did do fastboot oem lock, and it results in an unbootable system. fastboot oem unlock makes it bootable again. Not sure why. Also, whenever I do adb sideload <any_rom> it fails after about 45%. Not sure what's happening. Your instructions would get me to Nougat with TWRP and an unlocked bootloader, which may be what I end up doing, but I was trying to get back to fully stock, and locked again, so that OTA's will work properly. If nothing else works, I will go the route you suggest above.
Thanks again!
I just figured I'd try to get you to a working system/phone. After you get all that working you can probably lock your bootloader back to default. Now, I'm not 100% sure, but I believe that if you have a custom recovery you will need to restore that to stock as well before setting the bootloader back to locked.

I also have the same problem, after the bootloader lock the phone does not start.
I tried with all the possible procedures, also even the rom flash in local and sideload it does not work, It comes to 45% and then fails.
we will highlight the problem, so everyone will know and maybe there is a solution

But of course, you can't relock phone with a non standard recovery. Replace TWRP with the ROMs real recovery and relock will work again.
That's what I figured. Thanks for the confirmation.
Use the unbrick tutorial to go back to stock
This is what i did

I'm sorry, even with the stock recovery but does not work, it was the first thing I did
You can a unbick tutorial. It worked for my OnePlus 3T. Just search up How to unbrick (whatever OnePlus device you have) on Google. Then follow all the instructions carefully. If you need help with it I could try to do a remote session with you. Edit: It will erase all data and you will boot with oos 3.5.3 ( I also had the same issue as you. But I couldn't install any zip with stock recovery or adb side load.
Haven't seen nothing on the fórum about this particular subject, locking the bootloader seems a problem in this phone

Only if you have modified the phone in some way or another (like rooting and installing twrp) before trying to re-lock.
If you keep it stock, you should be able to re-lock. Or else, just use the Qualcomm restore method to re-lock.
tried this
OK what i did was when the phone was starting and vibrating I push the power bottom and volume down bottom at the same time ,then i connected the phone to the PC,from the panel in the phone there are 3 categories to erase everything on the phone I did it all(1,2,3) and then I put the phone in ADB mode from the control panel in the phone,After that I flash via fastboot the original .zip from one plus for the version 4.0.3 (1.4 GB) ,when it finished I restarted and the phone started normal again,I hope this help someone alse,I was so desesperated:silly:.
I think the problem in re-locking it is the modified boot image. Locked bootloaders don't support those.
re-locking bootloader will getback the warranty ???
No solutions till now

Unlocking the bootloader does not void the warranty on this device:
https://oneplus.net/support/answer/will-rooting-or-unlocking-the-bootloader-void-my-warranty
Once I have root, is there a command to re-lock and later eventually unlock the bootloader again?
I remember this was possible with google nexus devices, there was a shell command (require root) that was able to change bootloader status
Hello team,
I had 4.03 with unlocked BL and TWRP installed. I reinstalled the stock N recovery first. When I use the command "fastboot oem lock" it ask me to say yes and I do, it reboots and flashes the white symbol and reboots, stuck in this bootloop. Anybody seen this before or have a fix? I am trying to restore to stock to sell.
thanks,
Nope I didn't have an issue like you. 2 attempt of going back to stock and never had an issue. Did you successfully flash the stock recovery?
Just use the unbrick meathod it resets everything

Yes- I did flash the stock recovery. But when I do the "fastboot oem lock" it just boot loops- any ideas?

You should never lock the bootloader with non stock recovery or boot image. The security in newer devices is a lot meaner.
There are two ways you can resolve this:
Method 1:
You'll need to unlock the bootloader first. Try getting into fastboot and run "fastboot oem unlock".
If it allows unlocking you're done, just flash everything stock (first the recovery and then OOS 4.0.3 via the ADB option in the recovery). Then, go to fastboot and relock the bootloader. Should work since it worked many times for me.
Method 2:
If it doesn't allow and you're in TWRP you can't do any flashing since the locked bootloader won't allow TWRP to boot.
In this case, contact OnePlus Support via Live Chat and tell them you got a software issue with your phone.
They'll give you links to three files needed for flashing the device. Download those and let them know. They'll flash your device via remote support within a week. No matter what S/W state it is in.
Hope it helps
I'm using the last build of the Concept program for the Z3 Compact, .3657
This is what I've learned and tried:
- We're to use the recovery partition, FOTAKernel doesn't seem to apply.
- I've tried to flash different versions of TWRP, the one in the official site, 3.3.0-arian and even 3.3.1-0.3-z3c. They all flash without any problem while in Fastboot but I can't get into them afterwards. Choosing to boot to recovery from the Fastboot on-screen menu or pressing Vol- & Power while the phone is off boots to the system.
- Trying to boot directly to them leads to an error: FAILED (remote: 'bootimage: incomplete or not signed'), so I'm guessing that even though the bootloader of the device is unlocked there's still some kind of signature checking being performed by the bootloader.
- I've tried to use Magisk from another device to patch the boot image of the Z3 Compact and then flash that image, with the idea of getting a provisional root access and then go full Magisk but it doesn't work either.
Is there any way to have root access on Concept? I wouldn't mind using a /system based root manager but since I can't even get a custom recovery up I can't install it.
If anyone knows the right procedure to achieve it, please let me know, I'm interested on running that for a while.
I was locking my bootloader to try to reroot and pass safetynet. So, I factory reset it, set it up, and then went into the bootloader and typed "fastboot flashing lock". I selected yes to confirm the locking of my bootloader and then my phone rebooted. But now my phone says "Can't find valid operating system" and I can't boot into Android. i was able to unlock the bootloader again but now i don't have magisk installed and I can't even boot into Android to install anything. Is there anything i can do to fix this?
Yes, if you're bootloader is unlocked then you can fastboot flash (or use Chrome web based Android Flash Tool) factory images from https://developers.google.com/android/images
If you want to root extract the boot.img from the zip and patch with Magisk, then fastboot flash boot magisk_patched.img after you boot the phone once on stock unrooted kernel.
Thank you. I did it with the flash tool. Then later, it happened again and I realized I could use the boot.img. I'm glad these Google pixels are noob friendly.
Never lock your bootloader unless you know for a fact that you are on bone stock OEM firmware.
