Oneplus 6 bootloader relock

I have recently brought oneplus 6 from aliexpress it came with hydrogen OS so I want to install oxygen OS. I find the way to install oxygen OS by unlocking the bootloader. Can I relock bootloader after installing oxygen OS or relocking bricks phone as in Xiaomi? Please help. Thanks in advance.
Yes u can relock the bootloader i saw a video explaining it, but idk about after switching from hydragon to oxygen ?
Just use the unbricker to flash OxygenOS. That will take care of evreything including the locked bootloader.

I need help to install a specific firmware update

Hello. I've just unlocked the bootloader of my oneplus 7 and installed TWRP & Magisk.
Now, I searched for a bit a list of all the firmware updates for this phone, but didn't find much.
In the end, I found this page with several downloads:
https://androidfilehost.com/?w=files&flid=295474
Since for Android 9 I see only versions 9.5.7 and 9.5.8, is it correct to assume that version 9.5.8 is the latest update for Android 9?
(I don't want to upgrade to Android 10)
If yes, which file should I choose between these, and how would I proceed to install it, possibly without losing root and TWRP?

Thank you very much for any help. I really don't know where to start (and can't find much, if anything, by searching).

Any way if u want to install android 9 then and without removing root..then you can download latest ota 9.5.8 of oxygen os GM57AA
-flash rom from twrp..
-flash twrp installer
-reboot to other slot
-flash magisk
-reboot
Now u r on latest pie build of oxygen os ...with root
Yes thanks, all the precise instructions were in threads linked in that main help thread...

Lineage OS 17.1 won't boot after update notification on Redmi 2 prime

I was running Lineage OS 17.1 without problems in a Redmi 2 prime. Today I got a notification update from July 24th and then proceded to download update, then I clicked on install, then the phone booted again to TWRP and it won't boot into OS again, what should I do?
Thanks a lot.
You should reflash lineage os.
(You need lineage recovery to update lineage os)

So if a recovery wasn't installed that's why is not booting to OS? if I reflash lineage os my information will be deleted?
Any other way to make it boot to lineage, I'm confused...

Install LineageOS on an Android 12 device?

My Pixel 4a is currently running the Android 12 beta. I understand that if I install LineageOS, it would go back to being based on A11, as there is no A12 LineageOS yet. However, am I able to go straight from A12 to Lineage, or do I need to flash stock A11 and from there install Lineage?
The safest choice is probably flashing back to stock A11 before installing lineage.

SOLVED: POCO X3 NFC stuck in boot/recovery loop after flashing Lineage 18.1 official SOLVED:

New here...
I was using lineage 18.1 unofficial on my poco x3 nfc... worked well.
I flashed the latest surya Lineage 18.1 official... (followed the guide on recoverymode dot com)
after flashing, phone will begin loading the lineage logo... after 30 to 40 seconds it restarts and goes back into TWRP.
In TWRP there is now a warning/error message in red letters....
"android rescue party trigger! possible solutions? either 1.wipe caches, and/or 2.format data, and/or 3. clean flash rom"
I tried going back to the 18.1 unofficial lineage rom... same behavior and message....???
I read a lot online and believe it may be Magisk but am at a loss as to how to proceed and fix the issue to get my phone working again !
TWRP 3.5.2
Magisk 23.0
Any solutions, advice welcome... first post here so hoping some Big BRAIN has a fix for me... thanks in Advance !

You should follow the instructions given in the official Lineage thread.
It's not possible to dirty flash official Lineage over unofficial.
If you want to take the safe route:
- Flash latest MIUI fastboot ROM (don't relock your bootloader)
- Flash TWRP recommend in the Lineage thread
- Flash Lineage, GApps, Magisk according the instructions in the Lineage thread
thanks for your speedy reply...
yes I want to take the "safe route"
I am downloading the latest MIUI fastboot rom.... do I install with MiFlash tool or adb?
I have only been at this game a few months and have had no problems up until now... still a bit green...
Thanks in advance

Use Miflash tool. Once you successfully flashed MIUI, the rest is rather easy
Cheers m8... many thanx !!!
