Question Relock Bootloader

[fma388]

Hi all,

After multiple issues with this phone, I finally opt out and pass to Pixel 7 Pro.

So, i would like to know how to relock bootloader avoiding the problems of bootloop.
I've uninstall Magisk with option "complete uninstall".

I saw it's better to flash stock image before relock bootloader but how ?
Simply by flashing boot.img on the two slot OR flashing full.zip generated by Oxygen Updater OR other method ?

Thanks a lot for your help !

+1 for leaving OnePlus lol

You need to do both, flash the boot.img, then flash the full zip from oxygen updater
And then after a full reset and full boot up you can relock the bootloader.

This phone was promising on paper but the user experience was much less so...

Thank you for the answer !!

For the full zip of Oxygen Updater, I flash it with "fastboot flash full.zip" or how? (I've never flashed a full zip )

You can use the Local installation system, from the update screen and it that does not support use the OPLocalUpgrade app that Oxygen Updater provides.

If you're on the latest rom there is no need to relock the bootloader

But if you want to, download this https://gauss-componentotacostmanua...23/03/21/b6cfe6d4ec4f4cf7bcb316891f9f8db9.zip
It's the full NE2213 C30 zip file.

Than download https://oxygenos.oneplus.net/OPLocalUpdate_For_Android13.apk
Intall it on you phone, It will show a new app Local Upgrade, using this tool you will install the above zip file.

After the installation complete, it's recommended to full wipe your device.

Than using adb and fastboot that you can download from here https://forum.xda-developers.com/t/tool-minimal-adb-and-fastboot-2-9-18.2317790/

plug you device into your computer
reset it to fastboot mode (turn off, hold power, vol + and vol - until the device start than release power button, once the screen shows the options you can release all buttons and choose fastboot mode if its not there)
on the command prompt type:
Fastboot flashing lock

And that's it.

Thank you so much. Your advice's no need to relock the bootloader, i just worry about the information security. Eg: Banking app can work normal?
After updated to oxygen 13, my phone appear the warning: "phone has been unlocked and cant be trusted ..." each time i boot my device. How can i turn off this warning?

There is no reason to worry about that warning. As your bootloader is not locked the only breach is that a user can manually flash another firmware.
But as he will not have the device on hand there is no problem.

My advice is to not relock, many users bricked their devices doing that.
Also everything works just fine, so no need to relock.
