I had switched to lineage os 17.1 and now want to lock my bootloader. I'm back to stock rom and recovery but I'm a little concerned as I'm not sure about the use of vbmeta and if I need to enable the boot verification some way or not

How to unroot and lock bootloader on OOS 5.0.5?

Is there any alternative method to lock bootloader and unroot the device? I have read other topics that it will required to flash back to 4.0.1 version and install stock recovery.
Possible to have adb lock bootloader and reflash latest OOS 5.0.5 without flashing Magisk module?
Sent from my [device_name] using XDA-Developers Legacy app
Switched last week from Pixel Experience 9.0 (unencrypted) to OOS 5.0.5 and locked the bootloader.
Flashed the latest OOS from TWRP (with all wipes done before);
Waited for the phone to boot OOS 5.0.5 once - without root the TWRP is gone ,replaced with stock recovery;
Rebooted to stock recovery and performed another factory reset;
Waited for the phone to boot OOS 5.0.5 again (to be sure everything it's fine);
Rebooted to bootloader (fastboot) and executed: fastboot oem lock command;
Done!
P.S. - Backup your files before any wipe or bootloader re-lock.

Do what the previous response says. Just flash the 5.0.5 full zip, reboot to wipe TWRP. Then relock bootloader.
I suspect the only reason the guide you mention, says to flash 4.0.1, is because the guide is old, and 4.0.1 was just the latest version at the time. There isn't any requirement to "downgrade" to an older version, to return to stock/unrooted/locked bootloader.

Didn't you face DM-verity warning?
If yes, then how you removed it:-by
"ADB sideload" command or by any other means?
Please specify..........
If I had extra problems, for sure I would warn you about them. No warning, no problem, full stock "like out of the box"!

As per my knowledge, if you flash oxygen OS OTA without magisk then DM verity flag must be triggered, which only goes by sideloading the same OTA file or updated OTA zip file.
No idea, I told you the steps I made few days ago. They worked for me! Want to believe, good. Don't want to believe, even better.
Was on OOS 5.0.4 (bootloader unlocked), decrypted to test Pixel Experience 9.0 for 2 days and then returned to "full stock" OOS 5.0.5 (bootloader locked) to send the phone in service for upper speaker problems. I know it was not necessary to lock the bootloader, but it was my personal choice.
P.S. - Stop quoting the previous post, it's not necessary.

DM verity is triggered when changes are made to the system/kernel. If you flash a stock OTA file (with no Magisk or other changes) then DM verity is not triggered. Maybe it will be triggered when TWRP is still on the device (not 100% on that), but that will be taken care of when TWRP is overwritten.
You can sideload the OTA as described on the OnePlus website, if you like. But I don't think the result will be any different.

[Q] After installing Magisk,flash stock boot.img,stuck in fastboot mode

After installing Magisk succesfully,I try to revert back to stock boot.img used fastboot flash.
Then My phone stuck in fastbootmode,no matter which methode used to reboot.
Only solution is flash Magisk patched boot.img,then everything goes ok.
My question is how can I revert back to stock boot.img to get ota update?
use DM-VERITY & FORCEENCRYPT DISABLER

Unlocking Mi A2 is good idea? And How risky?

Hello everyone can anyone tell me how risky to unlock Mi A2? Before this device, I have used nexus 4 and Nexus 5 Galaxy S5, Those devices where easy to unlock, I saw posts here people had issues after unlocking this device. . I am happy with stock pie but I want to enjoy custom ROMs
So any suggestions please??
It is very easy to unlock bootloader but the tricky part comes in with the twrp flashing and installing custom roms since this phone has a a/b partition
Currently running on havoc os and it is buttery smooth with great battery life I would recommend to switch to a good custom ROM from the stock ROM
*Improper flashing in twrp will end up in a boot loop and after flashing twrp always switch slots and same with the ROM also to avoid boot loop

To make it easy I will share how I did it
fastboot oem unlock
fastboot flashing unlock_critical
Download twrp zip and image then
fastboot boot <twrp.img>
Then transfer the zip file then flash it
After flashing do not reboot
Go to reboot option in twrp then change the current slot wipe dalvic cache cache format data then reboot

Stock boot.img is not booting on boot_b

Hi there,
I've been rooting phones since Android 2, but lately it has been quite a challenge.
What I did so far:
Unpack new Xiaomi MI A2 (jasmine) device
Enabled Developer, USB debugging, OEM unlock in Android settings
Code:
fastboot oem unlock
Code:
fastboot flash boot_b TWRP-3.2.3-jasmine-20180804.img
TWRP ran fine. However, started with boot_a again.
OTA updated (about 6 times) to the newest version (Android 10, QKQ1.190910.002 V11.0.12.0.QDIMIXM)
Code:
fastboot flash boot_b twrp-3.4.0-0-jasmine_sprout.img
TWRP started only to the splash screen (showing "teamwin" and "Recovery Project 3.4.0-0"). Why is TWRP not starting properly?
Downloaded the stock fastboot image V11.0.12.0.QDIMIXM from https ://xiaomifirmwareupdater.com/archive/miui/jasmine/ and flash the stock boot.img via
Code:
fastboot flash boot_b jasmine_global_images_V11.0.12.0.QDIMIXM_10.0/images/boot.img
(my goal is to later patch it with Magisk and then install the patched version). However, the stock boot.img just hangs forever on the androidone screen. Why is the stock boot.img not starting properly?
I haven't used the Mi Unlock app and I didn't do an "fastboot flashing unlock_critical" yet. Is this necessary? What do I have to do to make the boot images work?

why do you feel you must use boot images ...the tried and working method for "jasmine" is to boot custom recovery and then flash magisk zip ( root only ) ..or...flash custom recovery installer zip which will flash recovery to both a/b slots.. then flash magisk
to properly boot you need to overcome stuff like secure boot and force encryption
if you aren't planning on custom roms just boot twrp to flash magisk
or
flash installer zip for recovery and wipe everything including formatting data to remove encryption and boot directly to recovery to install custom rom
twrp custom recovery had problems with decryption on stock rom ...secure boot won't allow booting modified images ..
lastly remember on jasmine there is no recovery partition..so everything is in the boot image ..magisk and recovery ..so everytime you flash stock , stock boot overwrites these changes and should flash everything again
tbh that's why i converted to wayne to get old partition layout as the A/B story pissed me off

Ok. So I'm back to Stock image jasmine_global_images_V11.0.12.0.QDIMIXM_10.0 by executing "flash_all.sh". You are saying I should "simply boot". You mean:
Code:
fastboot boot TWRP-3.4.0-0-jasmine_sprout-for_V11.0.12.0.img
right? That doesn't work, it won't boot. How do I overcome secure boot and force encryption?

yes im saying that but post a pic of the error ...why or how doesn't it boot ..
if it is the official twrp just dump it and look for the unofficial Russian one or one modified by Nebrassy or use Orange fox and or Pitch black ..official is broken last time i checked
also the name of that looks like one hell of a job ..shorten it to
recovery.img or twrp.img
fastboot boot recovery.img
but first run
fastboot getvar all
& also run fastboot flashing unlock_critical
but most importantly get another recovery
& i don't want to insult your intelligence but after flashing stock did you check to make sure bootloader was still unlocked and that dev settings was activated and that adb was toggled to on and that you authorised adb again
basicall after stock boot device and do the above ..plug in usb ..toggle adb ..authorise ..run adb devices ..if you see your device ..adb reboot bootloader ..fastboot devices ..see your device ..fastboot getvar all ..see bootloader is unlocked ..fastboot flashing unlock_critical if not done yet ...make sure to do ALL the above again after data gets wiped.....put twrp in adb folder ( MUST BE UNOFFICIAL RUSSIAN OR MODUFIED BY NEBRASSY ..rename to revovery.img ...fastboot boot recovery.img .. use file manager to put magisk.zip on internal then flash ..then reboot to rooted phone with stock recovery ...

Of course it is the official one. OMFG twrp-3.4.0-0-jasmine_sprout.img is broken (freezes on the TWRP splash screen), but version 3.3.1 seems to work. That's a relief, so I will try to flash magisk now. Although, I think I will need to do the decryption thing for jasmine first, but I guess I'll follow https://www.the***********.com/install-twrp-recovery-root-xiaomi-mi-a2-a2-lite/ mostly

jajaja well now you know ...be careful ...some "official" roms are also more buggy than unofficial ones for Jasmine/Wayne..
LOS is an example ..so be forewarned .. if you like android 1 i guess stock rooted is a smart option to keep updates and keep device certified for google stuffs . .
alternativeky go FULL custom rom because stock and custom recovery is just a pain and not worth the hassle on an A/B treble device flashable by fastboot ..just boot the recovery when if ever needed
fyi ..you can flash magisk and it will boot ...if you don't try changing the recovery ..so you can have stock rooted with magisk without rcustom recovery...* recommended by me if you only wamt stock with root

All good now, thanks for your help! I just flashed Magisk (and also TWRP) and everything works nicely! I will need to get some experience, but I'll keep in mind that I maybe want to get rid of the TWRP recovery. Finally security testing is fun again. Thx!

boot.img causes bootloop

I've been trying flash pixel experience on Redmi Note 9 and it had always caused brick.
When I flash vbmeta and boot.img I can access the Recovery but system goes in bootloop. Then I flash stock boot.img for miui 12.5.2 it successfully boot system but Recovery replaced to Stock Recovery.
I flashed the system through recovery after I flashed boot.img and reboot into recovery. After that I Replaced the patched boot.img to stock one then successfully boot.
I am using PE now but can't go to the twrp.
What is wrong here I really need an answer.
Try to flash the full stock MIUI again.

I tried 12.0.6. Same. Tried 12.0.8. Same. Tried 12.5.2. Same.
Can't flash through SPflash as last time it locked oem unlock and miunlock couldn't unlock.
Yes, you can if you are flashing the stock MIUI.
