Hi! I have one query. I m on stock 11.0.7.7. with modded boot img which i modded through magisk. I want to revert to fully stock and relock my bootloader. What do you suggest? Should i flash my stock boot img? ( Still got it) if yes, do i need to flash on both a and b partitions? Or should i simply run fastboot flash boot.img ?

guys, I was on the newest A11 build (11.0.7.7.IN11BA) and then I used fastboot rom 11.0.0-EUROPE-OnePlus8ProOxygen_15.E.30_OTA_0300_all_2009301818_f85a40a8ec66246-FASTBOOT

flash was successful but now I am in the bootloop, meaning that I get restarted to fastboot everytime (OS is not even booting), even after erasing the data.

is there anything I can do to fix it? :(

If you can download the newest build, even if it´s not a fastboot, you can use the payload dumper to extract the files, then just put the files on the fastboot rom folder, selecting replace. Then flash.

I'm on Pixel Experience latest, how can I revert back to stock, I'm unable to do with the above method
If the lastest fastbook version doesn´t work, download the latest stock, then extract the archives using payload dumper, and replace the fastboot version with the archives you extracted. Then flash.

Things are changing with the advent of project treble and seamless updates. OnePlus will no longer release ROMs flashable via recovery (either stock) because is no more needed. The updates will be done on the slot not used for example if you are using slot a the update will be installed on slot b and the slot b will be set as default. If you brick and you are in bootloop how you can restore the rom? You can't with Stock ROM you have, because the zip can be only installed via Update Engine, so what can you do? Flash a stock rom via fastboot. I have extracted all images from the stock zip and i have made a new zip with the Fastboot ROM with a flash-all.bat included. This will work only if your bootloader is unlocked. This will erase all your data and will wipe your internal storage.

HOW TO FLASH
This version is only for not branded devices
Download the zip;
Unpack the zip in a folder;
Reboot the OnePlus 8 Pro in fastboot-bootloader mode (Power and volume + and volume-);
Connect the OnePlus 8 Pro to PC;
Run flash-all.bat flasher you need;
Wait until the process end;
The phone will automatically reboot.

If you want to manual flash these roms these are the commands (You need the latest sdk platform tools, you can find it here

If the rom seems doesn't start go in recovery stock and follow this guideline: English -> Wipe data and cache -> Erase everything.

How do I lock the bootloader? I tried flashing both global and india version and I get this error after I lock the bootloader "Your device is corrupt. It can't be trusted and will not boot". I can unlock it fine but I need to lock it again.

My phone model says IN2020

I had originally used this tutorial to install lineageos https://wiki.lineageos.org/devices/instantnoodlep/install

Edit: I updated my android version from the phone interface and then was able to lock the bootloader.

    I want to thank all those who supported me, in 2 days I have already managed to buy the OnePlus 8 Pro, I will receive it in about a week and then I will immediately get to work. I will remove the link of the Paypal moneybox and let it close by itself so as to keep it in the historical (it will close tomorrow). A big thank you to everyone.

    You can do this yourself.

    Step 1: Download your official firmware
    Step 2: Extract payload.img
    Step 3: Use Payload dumper to dump payload.image
    Step 4: Copy dumped files to the root of the Fastboot rom directory
    Step 5: Flash :)

    As I understand this, this is for the European version so far and not the US version, correct?
