Needing help with QFIL

Hi, I need help about relock bootloader and restoring stock rom with QFIL, basically I need to go back to full stock to enable VoLTE.
I read in many threads to flash a version prior to the ZUI 3.5 with QFIL and next to flash the 3.5 version with QFIL, why?
Why I need to flash a previous version than 3.5 QFIL? Can I flash directly the 3.5 QFIL file?
Thank you.

Here I see a 3.5 QFIL(QPST) and in the instructions is written to flash 2.5 previous, why?
If you did this already, have you flashed 2.5 first?

this is Not the stable version, actually its a ota Of dev version but flashable with qpst if you directly flash this version your device will not boot or you may bricked your device.

Oh, now I undestrand, so in my case I just need to install 2.5 and next re-unlock and flash a TWRP (I guess).
Many thanks

For going back to stock, following is what I do.
1. Flashing that vendor to factory ZIP for becoming non treble in case I am running AEX or such treble ROM.
2. Flashing 1.9 Chinese ROM first via QFIL
3. Flashing latest Indian (2.5) or Chinese (3.5) via QFIL.
Works for me.
Gives me locked bootloader, stock recovery and ROM. Basically back to bone stock phone.

Yes, you're right, to lock bootloader the 1.9 rom must be flashed first.
And next if you don't want to use QFIL you can install an OTA package directly from phone.

Relock bootloader of rooted A2 Lite (Stock Rom)

Hey guys,
i just want to ask if there is a tested method to relock the bootloader of a rooted A2 Lite.
I use the stock rom, just unlocked and rooted it.
I've read something about the MiFlashTool and the Clean and Lock Option.
But I'm not sure about that, because the MiFlashTool is for Miui.
So what are the steps to relock the bootloader?
Thank you for your help

The MiFlashTool is also for the Stock Rom of the Mi A2 Lite (Not only MIUI!)
Download the Stock Rom and you can flash it via MiFlash. If you choose the option, you can relock the Bootloader when you do this.

Woah there buddy, if you try to lock a rooted phone you will have a hard brick. Don't try to lock the bootloader of a phone that is rooted or have system/boot etc. modifications.

Not sure if it would work, the cleanest way would be to download official fastboot ROM, flash it via MiFlash (select clean and lock option). This will erase all your data and turn your phone to stock ROM. I'm saying this is the cleanest way because you may have issues by unrooting and locking the phone. Maybe it would work. Unsure.

Ok, this was a misunderstanding

If you lock your bl at a modified system, you will get the message "your system got destroyed", I once had this. But I was lucky being able to unlock again... So no hardbrick... But doing all that leads to nothing. Btw. it's always useful to have an open bl... For example, if you mess up with a magik module and stuck @boot... Just ignore the stupid message of xiaomi!

To prevent this, i want to remove the root access in the first place.
That i have a clean stock rom.

I tried it with no-data-loss method and it says, system is destroyed, i have it to unlock it.
With root, you can relock it, but it's useless.

Backup up everything first
Download MiFlash and the correct ROM (not OTA version)
Then you can flash the Stock ROM which will remove everything
You can also choose to leave unlocked or lock the bootloader (re-lock is selected by default)
As this is a somewhat new device I wouldn't tick the option to save your data.

Take a look at this thread:
https://forum.xda-developers.com/mi-a2-lite/how-to/ota-v9-6-4-0-odlmiff-t3823913
you can find pretty much all ota's and fastboot rom links.
All full ROMs end with .tgz extension
like this one:
http://bigota.d.miui.com/V9.6.4.0.O...0.ODLMIFF_20180724.0000.00_8.1_4afd3431a2.tgz
you have to extract it to be able to use it with MiFlash but I'm sure you'll find all the answers in the thread above

Hardbricked mi Max 3

I ****ed up.
I was coming from miui weekly eu version, I wanted to flash a GSI image. I did in twrp, GSI pixel experience arm a only. Didn't boot further till mi logo. So fastboot flashed miui10 stable and booted till setup screen. Boot asked for a password after GSI boot. So I wanted to try a different GSI and reflashed. Didn't work also. Again fastboot flashed miui10, this time I forgot to unselect 'format and lock' didnt saw that. Now it won't boot in system and twrp, and also can't unlock bootloader anymore with mi unlocked as my phone is somehow not linked to my account anymore.
What am I supposed to do now?

Yes I tried flashing custom recovery. Says it can't flash it as my bootloader is not unlocked. Did the fastboot flash again because I wanted to do a deep clean flash again. But forgot to unselect the lock button. Now its locked and only booting in standard miui recovery and fastboot.

Why did you keep using fastboot to flash stock most of these need xiaomi.eu ROM as a base which can be flashed via twrp whatever version you use and it's because you chose flash all and lock hence your stuck now as can't unlock bootloader. I just recovered mine from ARB EDL brick as invought it cheap in that state. You need to flash a stock version version that's suitable to get stock working then attach your account in settings so bootloader unlock can work. My model was Chinese so I needed flash Chinese stock and started again. If your phone was originally Chinese start there then unlock the bootloader etc.

In a nutshell flash and lock with stock version for phone as if Chinese flash and lock won't work with a global stock ROM. Flash a Chinese stock to get back into system and start over again

Yes flash the latest official Chinese not global stock using mi flash tool as that will get your phone back up and running on stock. Then add your account in settings so bootloader unlock can see it. Enable dev setting tick OEM unlock and add account. Unlock your boot loader and your back again mate. If you could have unlocked your boot loader the global would boot but not while it's locked.
1. Flash latest CN firmware
2. Add account in settings after set up
3. Try bootloader unlock again should not have to wait if unlocked before
4. Flash twrp and keep copy of xiaomi.eu ROM on your micro SD card as that's all you need to flash in recovery to return to stock. It's flashed via recovery without errors

Anyone who can fix this hard brick gets $10 worth of Bitcoin or Ethereum from me.

Hmmm, if you bootloader can be unlocked. I can help you because I hard-bricked my phone because of the Anti Rollback by flashing an earlier version of global pie beta over the current one (10.2.1.0). I had someone from the s-unlock website unbrick my device for me because my Mi account had no authorization to finish the Mi Flash process. So instead, the tech guy used his authorized mi account to bypass the Mi Flash install remotely on my computer to make my phone work again.

My account is verified but I am not signed into it on my phone as I can not boot into system.

Basically you need to flash the latest version of the Chinese stock miui but I haven't seen any tool that does that while bootloader is locked. You won't be able to unless you have bootloader unlocked. It bootloader gets unlocked phone will boot normal but your account should still been linked as phone was signed into it previously. Strange that it won't recognise your account when using the bootloader unlock tool

That is the problem. I was booted into system but skipped the option for logging into my mi account as it was only to get past the unlock screen. Then did the clean flash again but then with the flash all and lock then I couldn't boot into system anymore. I'm seriously in trouble now, I loved this phone. Thankfully I still have a Mi A1 which I use now but it kinda sucks tho.

I guess its the end for this device.
I cant boot into system. I cant flash TWRP as my bootloader is locked (Token verify failed).

Go back to Stock ROM from Custom ROM (Help)

Hello you beautiful people ,
I recently purchased a Redmi Note 5 AI and i want to unlock the bootloader and flash a custom ROM since i'm not happy with MIUI, i have read about ARB and i'm fully aware that i can't flash an older MIUI ROM with a lower ARB than what i previously had.
But what's absolutely confusing me is if i decide to change my mind, how do i go back to Stock Everything (ROM, Recovery, Bootloader) basically and be able to receive OTA's from Xiaomi normally again? (I tried to search the forums to find an answer but i couldn't find anything so please don't tell me to check the forums).

You will get option to lock the bootloader or keep the bootloader unlocked
Yes this method will bring stock recovery and you will get OTA updates.
You have to download global ROM to flash it on global variant device
Or China ROM to flash it on Chinese variant device

Ahh thank you so much ^^, sorry i keep asking way too many questions, but where do i get the option to lock the bootloader again? and if i'm on miui 10.2.20 before custom ROM, i can flash the same MIUI ROM i was on or an older one as long as it has the same ARB value?
and is there a guide on how to flash ROMS and recoveries, because i am extremely confused >.<

In MiFlash software. Select clean_all and lock option to lock the bootloader
Yes you can flash 10.2.2 or any older ROM wich has ARB value 4 (you can flash any ROM between 9.5.19 to 10.2.2)

Question How to go back to stock and lock bootloader?

Hello. I have a LE2120 currently rooted with magisk i have all my files from when i rooted but i am thinking of selling and want to take it back to stock and lock the bootloader also becuz the updates wont install. Any help would be greatly appreciated.I wasnt sure if msm would give me issues or not so didnt try

Before you start .... Copy and backup all your data on the device.
Remove/Uninstall all Magisk modules and Magisk
Flash the stock from, Factory reset the device through recovery
Reboot to fastboot/bootloader and lock the device with connecting and using the command '' fastboot oem lock ''
All done

Use msm tool. That will wipe and reinstall stock and relock your Bootloader all in one step

Hmm, you should be able to upgrade, but you can't take incrementals, it must be the full update. Go to https://forum.xda-developers.com/t/oneplus-9-pro-rom-ota-oxygen-os-repo-of-oxygen-os-builds.4254587/
and download the local update file for the Indian device after you MSM. Unlock the bootloader, root it, and apply the local update in Settings.

Just use the MSM tool for India. I had just finished doing it few hours back. All good. My device LE2120
