bootloader unlock code different from frp unlock code.
installing other device firmware has chance to replace oeminfo.img partition. Changing this partitin often causes locked frp.
If lucky you can wipe from the erecovery that is loading. maybe even couple times. Then maybe it will boot. Other that that there has been no public mention of any fix.

do your best to fix it using hisuite or other methods if you can. if you have twrp that can help if you have stock recovery and locked frp your only hope might be hisuite and if that fails you will need a paid option like dc-phoenix or funkyhuewei. i only have experience with dc-phoenix, and it did fix my locked frp completely bricked phone, but i read that funky also works well but is nearly 3 times as expensive. (15€ vs 50€)

The displayed build number comes from the data part of the update. (Update_*hw_*.zip)
If you reflash again all three files , might be fixed

If flashing again is the answer to solve problem. Use my guide here.
You are on Oreo now so use the top portion. "Flash update"

I don't want to sound like rude or anything.
But I put it all pretty simple, I thought. Like 4 steps
Download files
Put files on SD card
Install twrp
Install file I shared
If that is over your head, maybe you should not have modify and phone.

Unlock bootloader, Install Custom Recovery and Lock Again?

Hi everyone,
Well my doubt it's really simple as you can see.
I tried to search on forum and internet, but I didn't found nothing solid.
Only achism (Incluing Mi official Forum)
It's really simple to Lock/Unlock the bootloader on Mi 5s, a simple command on promt and it's DONE. You lose nothing, no need to flash NOTHING.
I heard about bootloop, but does it real? Anyone here already tried it?
Why Am I asking it?
Well, if my bootloader is unlocked, I dunno why, but even with magisk Applications can detect some incoherence in my smartphone.
Even passing all steps of SafetyNet, the apps detect.
I think it's some flag on build.prop or another option available on MIUI Rom (and ofc they will read it to check everything).
My GF has magisk and custom recovery (Unlock Boot) and the same apps don't detect on her phone and works normally. (I configured both)
So I would like to know if it's really possible use a Custom Recovery and Magisk and just block the Bootloader again...

If you have the original bootloader from the original rom you can lock it. If you don't, the phone will stop booting with lock and custom bootloader.

No. Even using stock ROM after unlock bootloader and Install TWRP and lock again we got a message "the system has been destroyed" on Mi 5/5s/5x.
It's a Soft Brick, but if anyone on future want to try it and before do it, found this post so, stay away.

TWRP = different bootloader.

The bootloader for the G8s can be unlocked!!

I entered my device info (European G8s) on the LG bootloader unlock page and they actually sent me a key
I flashed it and the bootloader is now unlocked.
Are there any custom recoveries for the G8 so I can root it?

Just tried with my LMG820QM. Does not work. I was hoping it would because the G8s isn't on the list either.

Anybody with unlocked bootloader already tried to flash a gsi?
According to the G8, v50 telegram group gsi are fully working on the g8 without any special adaptions.

Anyone know how to unlock the LM-G850QM version?
Can't seem to find a way yet.

How do you lock the bootloader?
I bought an unlocked LG G8 ThinQ US Cellular version here in HK. Works perfectly fine but I receive the bootloader is unlocked message when loading up. As a result (or at least I think it's linked), when I try and install any banking app for Citibank on my phone, it insists my phone is rooted and I cannot use it. I have checked with as many different apps as possible and they all insist that the phone is not rooted. I don't need/want the phone to be rooted and I want the banking app to work on my phone, so I am trying to lock the bootloader. Apparently, this is doable using ADB and loading in fastboot, unfortunately, I cannot load the phone into fastboot mode. Any ideas on how I can lock the bootloader as it's not clear how it was unlocked in the first place? The version I have is LMT600US.
Also, if anyone knows whether locking the bootloader will somehow render my phone unusable - that would also be helpful as I clearly don't want to do that? :good:

Well, you can first try to install magisk manager and try to enable magisk hide (the default settings for play services and for your banking apps). If it says you don't have magisk, make sure you try and backup your boot img first and then click direct install. You can also hide magisk manager in settings. If you still don't pass safety net, clear data for Google apps and look up the pxl4xlprops module

I have an LM-G810EAW with Android 10 (V20a-EEA-XX) and tried to unlock the bootloader. Got unlock.bin from LG and tried to flash it, but got the message:
Code:
> fastboot flash unlock ./unlock.bin
Sending 'unlock' (1 KB) OKAY [ 0.009s]
Writing 'unlock' FAILED (remote: 'Flashing Unlock is not allowed')
fastboot: error: Command failed
Have I missed something?
EDIT:
YES, I missed to enable OEM Unlock!

System Update Failed? Here is Possible Fix

This Is For those Who Stuck At Android 9 In WW Roms With ZS660KL Model
This Method Will Use Raw Firmware so there is risks if you do something wrong and maybe data loss so always backup​Bootloader Must Be Unlocked
How To Flash Raw Rom:​1-Bootloader Must be Unlocked! (To change fingerprint to ww and relock the bootloader to get OTA) If you are already on WW fingerprint this step aint needed or you want to stay on cn fingerprint just skip)
2-Install adb and fastboot
3-Download and extract the raw version you want i will give some below
4- reboot the phone to fastboot mode and connect it to the pc Use Side Port
5-in the raw firmware folder double click flashall_AFT.cmd This will take sometime and no progress will be shown so all you have to do is to wait till the phone reboot or get black screen if you got black screen just hold vol down and power button for some seconds
6-if your Fingerprint is cn Change it to WW With root explorer you can find posta about this step by step (skip this if you are already on WW Fingerprint)

After this method You will get ota updates if you relock bootloader
or you can install update zips from asus if you want to keep bootloader unlocked :silly:

You don't need to unlock the bootloader to flash the raw firmware. That is stupid to say you do..

If you didn't rooted or touched boot.img just use this command in fastboot and the bootloader will be locked again

Question Bootloop to fastboot logo and back in lock state

Hi everybody,
yesterday I tried flashing the stock pocof3 rom back onto my phone, but since it got stuck in a bootloop at the fastboot logo. Showing the poco logo for a milisecond and then straight to fastboot..
(before this I flashed twrp and the arrowOS recovery and images a few time trying, without succes, to install this rom)
Last thing I did was flash via the mi-flash tool and did't see the "clean and lock" selection so it's also in lock state again.
I cant get adb to find the phone although the mi-flashtool is finding it.
anyone any tips?
I tried the vol up power trick, but this didn't help, keeps loading into fastboot

BAD NEWS... your Poco is bricked. You cannot flash ANYTHING using a PC when your bootloader is locked.
(I did same thing on a Mi11 5g last week and ended up selling it on eBay for spare & repairs
I tried sideload flash, miflash, copying update.zip to internal storage via ADB, and many other options - all without success).
- if your POCO is under warranty in your country (i.e. not a chinese import)... contact Xiaomi Support they can re-flash correct ROM
- Ask your local phone repair store... they *might* be able to flash original ROM back by using "Chimera" engineering software.

- Bootloader was re-locked whilst a custom ROM was in the phone.
(MIUI with Locked bootloader will not boot up where ROM is not stock or does not match the region/product code).
You cannot apply for bootoader unlock because you cannot boot up into Android and request the unlock via Developer mode.
You cannot remotely (via PC cable) flash any ROM into a Xiaomi / POCO phone whilst botloader is locked.
You are in a chicken and egg situation.,,, but if you find a way to repair your phone, please let us know how you achieved it.
Good luck!

If the system hasn't booted up yet there is a chance that you will be able to unlock bootloader again. Try it.

Connect the phone to pc and do the bootloader unlock again via the mi unlock app - you don't need to apply again and stuff as long as you're able to recognise the phone inside app correctly

Is it not even possible to flash Official ROMs?
Isn't there like a system that it checks the signature of the ROM and if it's a signed ROM it allows the flash? Or am I mistaken?

Nope bootload locked = no 'remote' flashes via pc
Apparently there is an 'authenticated user' mode for Xiaomi engineers in MiFlaah and also an EDL Emergency Download Mode which you can trigger by shorting out 2 pins on the motherboard so bypass bootloader lock and flash any ROM
Neither were available options for me

I'm now in the procedure to sent it back under warranty. any idea if this is possible and what the cost would be if not under warranty?
If all fails i'll try the shorting by pins, should be interesting

I think a warranty repair claim is your best bet ... I have never read anywhere that unlocking bootloader invalidates Xiaomi warranty (Unlike Samsung and so many other brands!)
If warranty repair is re refused try a few independent repair shops
Last resort is get the back cover off the phone and short out the EDL pins
Good luck!
Let us know if you manage to get your phone booting up again

I once hardbricked (complete blackscreen, not even Fastboot reachable) a Poco F3.
I requested a replacement from Amazon and that worked.
I said a software update bricked it.
Of course having to do that is really bad, but I was scared of opening the back.
