Return to stock Bell - One (M7) General

Hey xda! I was having trouble restoring my M7_UL to Bell Mobility stock OS, but with the help of the amazing people here on XDA, I have figured it out. here are the steps I took to restore from insertcoin back to stock:
1. download this TWRP backup: https://onedrive.live.com/redir?resid=61A88C96DFA8F691!624&authkey=!AC-6BqgL8HcbwjU&ithint=file,zip
2. download the matching firmware: https://onedrive.live.com/redir?resid=61A88C96DFA8F691!623&authkey=!ALE6X9YofxVQr8A&ithint=file,zip
3. download lastest TWRP: http://teamw.in/project/twrp2/164
4. reboot to bootloader, select fastboot, flash TWRP (fastboot flash recovery TWRP.img)
5. Boot into TWRP and backup just the boot, this way it will create the folder on your sd card with the correct name, otherwise backup won't show up
6. reboot into android. copy contents of TWRP backup to the folder created on your sd card
7. reboot back into TWRP. hit restore and wait for it to finish
8. reboot back into bootloader. select fastboot and boot into RUU mode (fastboot oem rebootRUU)
9. flash the firmware (fastboot flash zip 3.23.666.1.zip)
10. firmware flash will stop part way. this is normal. run the exact same command again and it will finish properly this time.
11. reboot back to bootloader (fastboot reboot-bootloader)
12. verify firmware has been flashed correctly (fastboot getvar all)
13. reboot, and take the OTA updates if you wish
14. this is where my instructions end. to finish restoring to 100% stock, follow this guide here, starting from removing the tampered flag: http://forum.xda-developers.com/showthread.php?t=2358738
I hope this helps!

Help with bootloop

Hi,
I did search, but I didn't find any solution to the issue. I got the Nexus 6P 64 GB.
I unlocked my bootloader using the 6p Multitool. Thereafter I used my normal method of fastboot (Minimal ADB) to flash the boot.img from this thread http://forum.xda-developers.com/apps/supersu/wip-android-6-0-marshmellow-t3219344.
After that I flashed TWRP. Basically I followed the instructions here: http://forum.xda-developers.com/nexus-6p/general/guides-how-to-guides-beginners-t3206928.
But my phone is not booting up.
It gives me this error:
Your device software cannot be checked for corruption. Please lock the bootloader."
But I tried that and it doesn't work. I tried from fastboot restoring to factory, but get the same message.
Please help me!
Did you check the enable oem unlocking in developer settings?
Sent from my Nexus 6P using Tapatalk
Yes. As I said, I achieved the unlock. Now I just can't get back into my phone or recovery or anything other than fastboot (where it says unlock)
isn't "Your device software cannot be checked for corruption. Please lock the bootloader." the new msg on boot when you are unlocked, and you have to wait ~10 secs before it startup ?
After that, I'm stuck on the Google screen. It just goes on and on. Left it for over 20 minutes at one point and it didn't get past it.
Edit: The multicolored animated google screen. The animation just keeps going and going.
Del.
Your issue might be due to the encryption of the phone. Take a look at this thread: http://forum.xda-developers.com/nex...recovery-twrp-2-8-7-0-touch-recovery-t3234976
From this thread:
NOTE: Decrypting data is not supported yet. The Nexus 6P will normally attempt to encrypt the device automatically on first boot. To use TWRP as you normally would, you will have to format data and install a slightly modified boot image with forceencrypt disabled. My Nexus 6P should arrive tomorrow and I will start working on decrypt once I get my hands on it.
Team Win Recovery Project 2.x, or twrp2 for short, is a custom recovery built with ease of use and customization in mind. Its a fully touch driven user interface no more volume rocker or power buttons to mash. The GUI is also fully XML driven and completely theme-able. You can change just about every aspect of the look and feel.
Read through that thread. Part of the issue is that I don't know which variant (MDA89D & MDB08K) I have, or how to find that out seeing as I can't boot into the phone.
If I have the variant I may be able to fix this through the unified toolkit (though I'm not sure of that)
Did you ever fix this?
Try flashing the factory image and starting from scratch. You must have messed up somewhere. Re-download the boot.img from Chainfire's thread, maybe that was corrupt or something.
1. Download the MDB08K factory image (it's not a variant, it's a Marshmallow update) and unzip it.
2. Download the MDB08K boot.zip from Chainfire's modified boot.img thread
3. Download latest SuperSU beta zip
Wipe phone in TWRP, to include format data.
In bootloader, fastboot flash MDB08K
fastboot flash modified boot.img (from zip)
In TWRP, ADB sideload SuperSU
Reboot and it should perform normally.

Thank you for your reply, but I can't get into TWRP either!! Any way for me to restore to factory or do the repairs from in flashboot without the restore?
I ran into the same issue last night trying to install TWRP. I'm still not sure how to get around it but I did get my phone back. you should be able to get to the bootloader (hold the power button until phone turns off, then hold vol up+vol down+power) once there use ADB fastboot to go back to stock.
this link will walk you through what you need. follow step 7.

here it is as well:
How To Flash The Factory Images (And Return To Stock)
Prerequisites: unlocked bootloader (section 1).
Download the appropriate factory images for your model here.
Unzip the angler-xxxxxx-factory-xxxxxxxx (x's replace variables) into a directory on your PC (for this guide we'll use C:\angler\).
Once unzipped you should have a folder named angler-xxxxxx (x's replace variables). Open it and move the following files to a new directory named C:\angler\images\:
bootloader-angler-angler-01.31.img
radio-angler-angler-01.29.img
(Please note that radio and bootloader naming changes from build to build so the filenames and below commands will change with them)
Within C:\angler\angler-xxxxxx\ you'll see another zip archive named image-angler-xxxxxx, unzip the contents of that zip into the C:\angler\images\ folder we created before. Now within C:\angler\images\ you should have the following files:
android-info.txt
boot.img
bootloader-angler-angler-01.31.img
cache.img
radio-angler-angler-01.29.img
recovery.img
system.img
userdata.img
vendor.img
Boot into the bootloader and connect your phone to your PC via usb cable.
Open a command prompt from within your fastboot folder (navigate to where you have fastboot.exe located on your PC, shift + right click anywhere within that folder, select open command prompt here), enter these commands to flash:
Code:
fastboot flash bootloader C:\angler\images\bootloader-angler-angler-01.31.img
fastboot reboot-bootloader
fastboot flash radio C:\angler\images\radio-angler-m8994f-2.6.28.0.65.img
fastboot reboot-bootloader
fastboot flash boot C:\angler\images\boot.img
fastboot erase cache
fastboot flash cache C:\angler\images\cache.img
fastboot flash recovery C:\angler\images\recovery.img
fastboot flash system C:\angler\images\system.img
fastboot flash userdata C:\angler\images\userdata.img
fastboot flash vendor C:\angler\images\vendor.img
Thank you. I was eventually able to do tysonwald's suggestion. First I didn't know what my version was, so I couldn't.
At some point I was able to get into the phone with constant gapp errors, check it.
Now my phone is unlocked and rooted. But when I go to settings to security (and when I tried to set up my fingerprint) settings crashes. Any ideas?
There was still some issue. I wiped the phone with the above method again, did NOT set up twrp/root, and everything works. It was something about the custom boot image I guess. Any advice if I want to try to set it up again?
Problem solved. Needed to update to newer image before doing everything. Issue resolve from Heisenberg's thread. Thank you all!
I had the same damn issue last night. Thise bootleg instructions had me flashing build k boot.img on build D. Maybe i wasnt paying attention lol!
I have a very similar problem, I flashed the k boot img. and now I'm stuck in an endless bootloop any idea?

Read thru this guide and follow the instructions to the T. http://forum.xda-developers.com/nexus-6p/general/guides-how-to-guides-beginners-t3206928
I had a similar issue just now where my phone got stuck at the TWRP logo. Selecting the reboot option in download mode refused to remove it. I had to follow step 10 to get my phone back to stock. I'm afraid to try this again now
Is there anyway to know which version do i need to download? i bought the phone already bricked and i am trying to bring it back to life

On step one. After you wipe system, data, and cache, your wiping the system to your active slot.the one your on. So I would say you would want to switch slots right here. So your new rom goes on clean slot.
In my experience so far after your step 5 you will have to fastboot boot TWRP again, because you just flashed a rom now and it's not signed anymore. So TWRP will not boot. Unless you have April bootloader in that slot, if you have may in both slots you will have to fastboot boot twrp. So far this is what I have had to do. I would like to know if someone has figured out how to flash a rom on may bootloader's without having to use fastboot.

Mac your right mate. I'm not sure you can do it but what I have noticed is that twrp rc1 is needed for may bootloader

Nexus 6p rebooting in twrp recovery

Hi, I was stuck in nexus 6p bootloop, but after following instruction here I unlocked the bootloader, and flashed the twrp recovery and 6pEX4 zip file. But now my phone reboots everytime into recovery. It doesn't reboot into system even if I select reboot into system from the recovery.
My phone bootloader was successfully unlocked. I, however, by mistake typed
Code:
fastboot flash boot
instead of
Code:
fastboot flash recovery
before flashing twrp. Do I need to install stock rom again and repeat the same process?
You don't need to start again, just go and run the correct command in the bootloader and it will overwrite.
Run the below
Code:
fastboot flash recovery nameofrecoveryimage.img
Then boot into recovery and flash that kernel zip and you should be good to go.
As long as you can get into recovery things are easy, you could always just copy across a kernel zip or whole ROM zip and flash that

fastboot help

I was flashing TWRP
I couldn't boot into system after flashing..
This is what I did:
1. fastboot boot recovery.img
2. Swipe to allow modifications in twrp
3. Flash TWRP installer zip
4. Reboot into partition B
5. Reboot bootloader
6. fastboot boot recovery.img
7. Swipe to allow modifications in twrp
8. Flash TWRP installer zip
9. Then I rebooted into recovery to check if recovery boots and it did.
But afterwards couldn't boot back into system. It was again booting into recovery.
I booted into recovery using fastboot boot, that's why it might won't boot into system. Is there a command to boot into system after above procedure?

Kindly also suggest source of files you used, if you know another working method.
I have the same problem. Meanwhile, flash the stock fastboot images.
Why do you want to have TWRP installed? I am following these steps each month (fastboot ROM was always out sooner than my OTA) without any issues.
1. flash stock ROM via fastboot
2. fastboot boot twrp-3.1.1.img and don't allow system modifications or you won't be able to apply OTA
3. install magisk 15.1
4. reboot to system
If first boot takes more than 2-3 minutes, hold power off button until phones restarts, second start will take the usual time.
I also don't allow any modifications from TWRP, and just boot to TWRP when I need to. I do not install TWRP.
Sounds like you'll have to do a miflash of the rom, then try not installing TWRP and not allowing any modifications in TWRP to system. Just use TWRP to flash Magisk.

[Guide] Honor 8 Oreo stock EMUI upgrdade.

I guess this is a bit late for a proper upgrade thread with a proper guide, but better late than never. I have an FRD-L02 and I'm using 8.0.0.513(C675) without any major problems. Without further ado, here's how I did it. Make a full backup before you start.
Perquisites
1. Unlocked bootloader. Huawei doesn't provide the codes now but you can still get them using DC Unlocker.
2. TWRP. Use this link - http://https://mega.nz/#!8xcyWTyT!OpMvPzMUAGPehDiqihi_gu6LViEltVECSIR743-KgrI
3. Firmware files - Use Firmware Finder from TeamMT. I downloaded them on PC. Makes life easier. You'll need to download three files -
i.update.zip
ii.update_full.zip (this can vary)
iii.public.zip
The links vary for different models so I'm just giving you a rough idea. If you are on PC you can just check in the common base for your device.
4. HuRU updater - Use version 0.4 http://https://forum.xda-developers.com/honor-9/development/tool-flash-official-firmware-recovery-t3769279
5. Stock EMUI recovery - Extract the update.zip and use HuaweiUpdateExtractor to extract recovery.img from update.app. Make sure verify header checksum is unchecked.
6. SD card or USB-otg to load the files.
7. A PC :laugh:
The guide :
USB or SD card prep
1. Rename the following files -
i. update.zip remains same
ii. update_full_FRD-L02_channel_in.zip becomes update_all_hw.zip
iii. update_data_full_public.zip becomes update_data_public.zip
2. Make sure all the following files are in one folder -
i. HuRUpdater_0.4
ii. recovery.img (this is stock EMUI recovery)
iii. update.zip
iv. update_all_hw.zip
v. update_data_public.zip
Flashing firmware
1. Reboot to bootloader and ensure that you have at least 80% battery along with Phone and FRP unlocked.
2. Enter the following commands -
fastboot erase userdata
fastboot erase system
fastboot flash recovery_ramdisk twrp.img or fastboot flash recovery twrp.img (depends on current android version)
fastboot reboot
3. Immediately press and hold volume up so that you boot into TWRP.
4. In TWRP, you'll probably get errors if you try and wipe straight away. Do a factory reset and reboot directly back into TWRP.
5. Do the necessary wipes - Dalvik, cache, system, data, internal storage. I was able to avoid many errors when I did a complete wipe.
6. Go the folder we prepped earlier and run HuRUpdater_0.4.zip. You'll have to press volume down to start flashing.
7. It'll take a while and after it's done boot into the system.
8. This method removes TWRP once you boot into the system and we are now on stock recovery. You will most likely encounter a bootloop on first boot. Don't worry, simply press and hold the power button to
power off and immediately press and hold the volume up button once the screen goes off to enter recovery.
9. Perform a factory reset by following the steps on the screen. Reboot!
10. You're done. Voila. Enjoy.
