Locked bootloader, no OS, no USB debugging, fastboot working (not rly) - Xiaomi Mi A2 Lite Questions & Answers

Hey! Today I rooted my Mi A2 Lite using magisk with fastboot. Let me go over what I did:
I enabled OEM unlocking and USB debugging in settings
I flashed the rooted img.
Me, being a retard, disabled USB debugging and OEM unlocking
Of course when I rebooted it said The system has been destroyed.
So, I've been searching all over the internet (went as far as page 3 of google results sometimes ) and didn't find a way to boot into twrp or anything with disabled usb debugging and OEM.
I've tried XiaomiTool and similar, nothing worked (device locked or similar message on anything)
The only way I've found is using test points on the motherboard. That's my last resort, but I want to know some things before I do it.
1. Do you know any way I could try and boot/flash an img?
2. Do you think I can do the test points thing at home (not an expert)?
3. Any tips on doing it?
Thank you so much if you are able to help, I really love this phone, hope I didn't screw it up

Been there a month ago for 8 hours
The popular solution is to disassemble the phone , disconnect battery and boot into EDL mode
But I downloaded the Mi A2 lite toolkit and messed with it ( the unbrick and boot to twrp options) after trying to flash 10.0.3.0 stock rom and miflash tool was deceiving me that it was flashing but it was not .. try to flash it by flash_all.bat
The stock fastboot rom : https://en.miui.com/getrom-354.html?m=yes&mobile=2
The toolkit : https://forum.xda-developers.com/mi-a2-lite/how-to/tool-10-11-2018-backup-restore-lock-t3865519
I downloaded the 1.0.4.1
Stay calm and remember it's just a piece of silicon a lot can go wrong but butor can go right everything has a solution

Mi A2 Lite bricked on stock

Hello everyone,
My Mi A2 Lite just died today. I was on stock 8.1 rooted and suddenly it freezes so I rebooted it and I got stuck on Android One logo WITHOUT ANY animation.
I tried to boot into recovery via adb but I get stuck on TWRP logo. I tried to flash fastboot image but nothing changes....
I really need help because I'm out of options

Two quick questions:
1.The phone died on its self without your intervention or...?
2.Have you tried to flash the stock firmware via MiFlash , while the phone is in edl mode(the command is: fastboot oem edl)?
1) yes, it got stuck so I rebooted it
2) I tried flashing with MiFlash tool in fastboot mode. When I connect it in fastboot edl the mi flash tool sees it as COM and therefore I’m not able to flash it.
I’m I doing something wrong?

I think you are confusing some things here; adb is not an option now so you can´t boot device normally and also you said "fastboot edl" but they are different modes.
While in fastboot how did you try booting to TWRP image? (you said through adb but this is not right)
Can you get to fastboot? (hold vol down while booting, should see a rabbit on the screen)

When your phone is in EDL mode(you won't be seeing any logo on your phone ,only black screen) it's absolutely normal to see the device as COM port , because the device is in another factory mode. And there is no problem flashing stock ,when your phone is seen as COM port. So if you can't flash the stock firmware in fastboot mode or EDL mode , maybe you have a hardware issue. To be sure -take a screenshot of the error in MiFalsh when the phone is in edl Mode (seen as a COM port) and you try to flash the stock firmware.
Ok, I understand the difference between EDL (black screen) and Fastboot mode. I can get in both mode. I tried to flash fastboot stock rom (taken from the thread in xda) and everything goes smoothly, but it stays in fastboot mode at the end and when I send the command fastboot reboot it gets stuck again on the Android One logo (no animation).
When I tried the EDL mode, mi flash returns something missing (I will post the screenshot asap) and it seems like is not the right thing I'm trying to flash or something similar (I will post more information as soon as I can). (I'm trying to flash the same fastboot roms found in xda)
So, just to make sure I'm doing the right thing, where I can find the stock firmware to flash?
Thanks again for your help!

Here is the stock firmware from Xiaomi site:
https://en.miui.com/getrom-354.html?m=yes&mobile=2
Don't worry that it says MIUI , the firmware is Android One , they just forgot to change the name from MIUI to Android One , I have already tried it ,and I can confirm that it's 100% stock Android One firmware , good luck!
Ok I performed the flash but the error i get is new.
I get the error ACK count don't match!
I tried the version
daisy_global_images_V10.0.9.0.PDLMIXM_20190514.0000.00_9.0_f9d0c739e0.tgz

I will give a solution in a minute
EDIT: Are you sure your bootloader is unlocked? (fastboot oem unlock)
You have two choices , you need to find an older version of MiFlash beta , i'll give you a video :
https://m.youtube.com/watch?v=-7O1Svib14g
In the video description you can find a link for the MiFlash beta ,I hope it helps.
If not , you'll have to consider the Testpoint unbrick method , there are several guides.
OK, thanks to the use of the BETA version I was able to flash the rom but unfortunately I still get the same AndroidOne logo without any animation....
I really don't know what to do now...
Yes the bootloader is unlocked and I checked with fastboot getvar

Ok , it totally sound like some kind of hardware issue with the storage . Is there any way to boot in TWRP ?
Download the TWRP version 3.3.3-1 offain and try to boot with it (fastboot boot recovery(the name of the recovery).IMG) and wait until the TWRP logo disappear. Wait at least 1 minute if the logo doesn't disappear , then in my opinion , you have a hardware problem , if you succeed to booting in TWRP download the GM 1.1 version from this thread :
https://forum.xda-developers.com/mi-a2-lite/development/9-miui-rom-t3960704
and flash it via TWRP. Then reboot and leave the phone without touching at least 10 minutes (until you see some movement like on the bottom of the screen , there will be a MI logo , right above the logo if you see 3 dots moving , then you're saved . From there we can proceed , but if you can't flash even this rom , if nothing helps. I hope you have a warranty , reflash the stock rom with the option flash_all_lock and go to your warranty service center.
EDIT: I googled and found another issue, that might be causing this strange situation: You may got scammed , and the device might not be a Mi A2 Lite , but rebranded Redmi 6X. See this thread:
http://en.miui.com/thread-5984082-1-1.html
If your phone is displayed "Wayne" ,not "Daisy" ,then you'll have to flash a Redmi 6X firmware to get rid of the bootloop

I will now try your solution, I just tried the testpoint unbrick method but still same problem.
The output from fastboot getvar all shows a DAISY bootloader. Where I can see the real name of the device to see if it is a Mi 6X?

So test point doesn't work too.. That's bad news
EDIT: fastboot getvar product command works , you can try it
And another question , have you tried to boot with patched boot.IMG ?

You need a recovery to flash , which has a specific partition in the phone storage. You can flash only via fastboot . You need to boot into recovery , so try with a patched boot image for your version of the rom

So the last resort , we'll try to flash the ROM that I have mentioned before via fastboot. Place the zip file GM 1.1 in your PC (it has to be in the same directory as your adb and fastboot tools)
then open cmd and run the command
fastboot flash (the full name of the zip).zip
and hit enter
maybe that will solve it
And if this doesn't help again... type these fastboot commands :
fastboot format userdata
fastboot format system
fastboot format cache
fastboot format vendor
fastboot format recovery
fastboot format boot
then try again to reflash the stock rom (first try in edl mode ,if this doesn't do anything ,you'll have to format everything via fastboot commands again ,and try to flash the ROM in fastboot mode)
And if this doesn't help too... Then you're free to hit that ? in the ground hahahah (just kidding)
Tried both these two last but nothig works, I always get the same problem.
I just saw your comment on patched boot, can you elaborate a little bit on this?
I'm honestly very close to throw it in the trash

which version of the firmware you are flashing? 10.0.9.0 or another version , so I can send you a link and walk you through the procedure.
And when you flashed the GM 1.1 the boot screen didn't changed from Android one? (the GM 1.1 version is a MIUI stock port and has to change your boot screen to black screen with white MI logo on it) It is very important to know
One of my friends told me to try this: just open the directory of the stock firmware , navigate to flash_all.bat and run the bat file (NOT THE FLASH_ALL_LOCK!!!) and wait for the end of the process. He had a similar problem , and it worked. He explained that for any reason , the recovery was the problem , because it was flashed in the boot partition. When you use flash_all.bat The file will erase all partitions and rewrite them. MiFlash won't , so try that

Locked Bootloader, No access to Operating System

I have a Xiaomi Note 8 Pro initially came with China Stable Rom V11.0.3.0.PGGCNXM. It was also unlocked.
I accidentally flashed Global Stable ROMV11.0.6.0.PGGMIXM via MiFlashTool and while it was successful, it rebooted to Recovery Mode with the message "This MIUI version can't be installed on this device".
After that, I pressed "Wipe All Data", so now the device is also locked.
Since there is no OS installed, I cannot access the device and consiquently to use Mi Unlock Tool properly to Unlock it again.
The device is now locked, without OS installed. However I can access Fastboot menu and Recovery mode.
Is there anyway to unlock the device in this state and flash it's original Rom again?
Please if you have anything to suggest that might help me, answer my question. I'm desperate. :crying:
Hmmm. Can you still access fastboot mode? If yes I recommend using miflash pro and flashing the correct rom for your device, or manually flashing all images via fastboot.
You've likely selected Clean all and lock (default setting) which flashed MIUI and locked the bootloader afterwards which bricked the device because of cross-region ROM flashing. Since you can't flash it with locked bootloader your only option is to take it to the service center.
@JuanM2020 @n0b0dy666 First of all, thank you guys for your suggestions.
Update: I tried to flash it's original Rom via MiFlash Pro, however when I connected my device on the final step, as for the SP tool to flash the Rom, my pc couldn't detect it. I even risked and disassembled the device to remove the battery in order to turn off the device, but it didn't work either. (Cdc & Vcom Mediatek drivers both installed properly on my pc).
The device is recognized by my computer when in Flashboot menu. However for the SP tool to work, it should be turned off, but recognizable from computer.
Before posting here, of course I went to a service center, but they told me because I tried to install Global Rom 11.0.06, while it's original Rom was China Stable Rom 11.0.03, I should wait for the 11.0.06, as a downgrade is not possible (not sure if it's true). We don't have an official Xiaomi Center in my county, where I go was the best chance I had.
Any other recommendations?

If you can still access fastboot mode flash correct images manually.
E.g.:
Fastboot flash system system.img
Fastboot flash vendor vendor.img
Fastboot flash recovery recovery.img
Etc etc

So sorry for my late response. Is there any guide about manual flashing which I can follow for that?

Question Bricked Poco F3 Global.

I was on 12.5.4 Global and wanted to switch to 12.5.6 EEA, and i've red here and there that was a "safe" operation. I've tried to unlock the bootloader and flash the rom, all the roms gave compatibility issues, so i flashed the 12.0.3 EEA, but it was stucked on the boot logo. I've read that boot into EDL mode and flash via MiFlash could resolve the thing.
I tried but MiFlash crashes everytime i try to flash a rom.
Could someone give an help?
UPDATE: Now is in fastboot, same problem with the stock roms.
Did you read any tutorial? For which reason you flash 12.0.3?
Looks like you triggered anti-rollback protection. Read here https://www.xda-developers.com/xiaomi-anti-rollback-protection-brick-phone/
You cannot install previous versions of miui.
If by some chance the phone still boots to fastboot mode, try to install the LATEST firmware for your phone via mi flash tool (make sure you check "clean all" option and NOT the "clean all and lock" which is default in the flash tool).
And no, you cannot use EDL with this phone. EDL is locked to regular users and can only be accessed by an authorized account.
If you ca access fastboot and the device is recognized by you computer in fastboot mode then you can flash Miui using MiFlash.EDL mode is when you dont have access to fastboot.
Read tutorials about flashing miui using miflash on youtube.

If u are in fastboot mode, install this : https://www.mediafire.com/file/lv98wac50a2dexz/MiFlash20210226.zip/file. extract and launch the exe, click on install. wait a pop-up in chinese and close all. Then re-try to re flash the EEA (in CLEAN ALL) with this mi flash. Tell me if all works

Or install via any mi flash lol.
It sounds like normal thing...
Cross flashing global/EEA tends to fail for whatever reason ( Super doesn't flash correctly ) and you get stuck bootlooping or straight towards fastboot depending on how far the super flashed...
Go back to global ROM and sit there. It should flash alright.
Idk why it does this ... Something is not alright with this phone
{Mod edit: Quoted post has been deleted}
Yes it's always 604 or 606 seconds for mi flash no matter how good your PC is either because I have a good one it should be like 2 minutes.
Wtf? What do you guys mean edl mode you don't boot into edl mode that requires you to take the back off and jump it with wires or something. You boot into fastboot mode like you did to unlock bootloader and flash with miflash and you don't go from 12.5.6 to 12.0.3 normally downgrading will brick your device. Where the f did you get all of this from. If you can boot back into fastboot mode volume down and power key until it boots into fastboot than reflash the last working firmware you had with miflash and look at the video. I don't understand what all the countries believe they can do with a phone edl mode is like OEM type fixes not some kid on Xda

You can always tell your on Xda when they offer help that is 1 link and try this is the only information they give. The reason you screwed up is because lazy people that don't leave full instructions. You never never never never need to worry about edl mode. Fast boot or bootloader mode as it's called is how you restore a soft bricked phone what did you do with edl mode I don't even understand what you tried to do.

You thought this is something you needed to do? Edl mode is nothing that a regular soft brick would require
Here's another one edl mode I can't understand why you or anyone else would think this is how we restore a soft bricked phone lol this would be crazy I would be done. Your not even close to the first person to say this. Same with battery backup that doesn't make sense it's not battery backup you don't backup your battery it's battery life

Question Poco f3 Error: Sending modem_ab

good evening
I have been trying to return to stock miui from Pixel Experience since yesterday but get this error every time I try to flash the Firmware and do not know what I can do about it. I would be happy if somebody knew what this error is from and what might fix it.
Same problem. Don't try more things because you will brick your phone like mine.
Thanks for your reply. What did you do that bricked your Phonem? This way I know what to avoid. Thanks you in advance
As you are sure your device is a eea one, try with this last official stable firmware : Version: V13.0.7.0.SKHEUXM
You can find it here https://new.c.mi.com/global/miuidownload/detail/device/1900394
Fastboot version here at bottom : https://xiaomifirmwareupdater.com/miui/alioth/stable/V13.0.7.0.SKHEUXM/
Or https://bigota.d.miui.com/V13.0.7.0...EUXM_20220627.0000.00_12.0_eea_e461331a7d.tgz
Thanks you so much I will try that
and i did not mention this but I started this whole project of returning to miui because my poco was and still is in a bootloop and is only accessible over fastboot, not recovery and even though it sometimes gets to the system it almost instantly crashes and reboots
Still the Same Error unfortunatelly

Ok,
Do you have any idea what you did that may have caused this bootloop ?
Have you used any Qualcomm Tools or any soft in EDL mode ?
No, I did not do anything that would mess with the system to my knowledge . which is why i really do not know what to do. Can This Error occur because of a USB 3.0 used to flash? The Phone even tries to reboot when it is detected as a Fastboot device, maybe This has Something to do with it. Maybe it loses the Connection and therefore the flashing process stops. Are there possible ways to fix This?
Try with the latest android platform tools.
Put the content of platform tools archive in the fastboot folder and launch flash_all.bat don't use flash_all_lock
Still the Same Error . Can This be because of a Driver or a hardware issue?
i had similar issues but with the super partition when trying to flash from cmd.
flashing with miflash instead solved it.
It doesnt seem to make any difference to the error whether i flash it via cmd or miflash

Maybe : So as you can try with other PC, USB cable, USB connector, reinstall USB drivers...
I already tried with two Notebooks, I will try again tomorrow with another PC and installing USB drivers again. Thank you
You could try redownloading the MIUI ROM... you got it from xiaomifirmwareupdater.com right?
And yes ^^, try other PCs/laptops and other USB-cables.
Just please make sure
Unfortunately, Fastboot-Flashing is a gamble. It's not a solid protocol. It has zero protection against sudden USB-connection loss.
And manufacturers like Xiaomi go out of their way and block Qualcomm's EDL Mode, which is the only way to recover your phone in case Fastboot Mode stops working, because that Mode itself can also get damaged.
Fixed - first flash a miui recovery rom from twrp make sure the rom version lower than the latest one, now flash and boot miui , now just update from miui updater once you updated to the latest version , now try to flash the fastboot rom that you trying to flash, it should work.
I cant access a bootloader like TWRP because the phone still keeps rebooting after a couple of seconds in the bootloader so i cant really do much. I only have access to fastboot

okay Im as far as I have never been with a very weird method, maybe somebody can explain. Because my poco always wants to reboot I found out a way to keep in in Fastboot mode. I repeatedly press the power and volume down button, This way it stays on for a lot longer, but it still is not enough to succeed at flashing the rom. It also lets me believe that my problem is not a software but probably a hardware problem, otherwise and cannot explain this suuuper weird behavior. what do you guys think? is there a possible fix you know?

[SOLVED] boot loop after i tried to fix broken root

I tried for like 3 hours to find a boot.img and i had root on my phone, but without wifi and sound.
a quick google search showed me that it was because i had a wrong version of the boot.img, afterwards i found another one and now after i have tried installing twrp, booting and flashing using adb (stock and modified versions of boot.img) but it just keeps bootlooping. in twrp i cant wipe, make a backup, see any files in /storage/ and i have no clue what to do next.
What model 7T do you have? HD1907? What was the rom that you were using before you installed TWRP on? OOS12 does not support TWRP. Custom rom A13 does not support TWRP. Only a few custom rom A12 and OOS11 support TWRP.
Idk but I'm just wondering if flashing the last working rom image (dirty flash)? That would eliminate TWRP(?) and eliminate Magisk(?) while hopefully keeping the device from being wiped possibly?
*** Hopefully someone could/would verify this before you attempt... ***
i was on android 11 but i cant remember the version, i have HD1903 (EU ver). i THINK i had the one from the oneplus website(https://service.oneplus.com/us/search/search-detail?id=2096229) but idk anymore

i cant find the file for my current version and it doesnt work if i try it with the only version that is android 11
and i cant turn my phone back on
and after i installed the drivers i had to restart my pc and now there is this thing at the bottom right:
testmode
windows 10 pro
...
i waited until my phone had no more battery charge and now im bootlooping again :/
nvm it just booted
im downgrading it now and i dont get the error "smth communication smth" in msmtool anymore
alr it worked my phone is wiped again but i can turn on wifi and sound
but how do i root my phone now? I have an Idea, im gonna write step by step what i think gets me a rooted phone please confirm if that would not break my phone ^^' (bootloader already unlocked)
1. enable usb debugging and allow my pc
2. download and install the latest magisk version from the github
3. download magisk patched boot.img for ver 11.0.5.1BA BUT since i cant find anything on the internet im gonna have to use the zip file from the unbrick tool thing (https://onepluscommunityserver.com/list/Unbrick_Tools/OnePlus_7T/EU_HD65BA/R/) and then patch the boot.img using magisk myself
4. then use platform tools and type following commands: "adb reboot fastboot", "fastboot flash boot {the patched boot image file}"
5. then use magisk to direct install the root thing
i just realisized the unbrick thing that i wanted to use instead of a boot.img doesnt have a boot.img in it... WHERE CAN I FIND A BOOT.IMG brooo androidfilehost.com doesnt have it the unbrick tool doesnt have it
omg i realized i could update my phone to 11.0.9.1 then download the same version from official website and use the dumper to get the boot.img **** meee
wait it sais its 11.0.9.1HD65 AA and not BA **** me
k nvm i just changed the site settings to germany and now its BA
i just went for it and now my phone is rooted thank you very much for your help i would've prob tried to revert back to stock for like 2 weeks and then cry that i cant root my phone thank you so much xd
