Weird bootloop with locked bootloader

Long story short, I ended up with a classic bootloop (shows boot animation continuously) from messing around with Magisk modules, so I did a wipe from recovery, still bootloop, so I tried reverting completely to stock with the OEM downloads. I tried flash_all_except_storage.bat, and flash_all.bat, but this time it was a different bootloop. The phone shows the Android One logo, the screen flickers like it's going to the boot animation, but then it just goes back to the Unlocked Bootloader Warning Screen, then the Android One logo, and loops like that. I dumbly thought locking the bootloader, reflashing everything, and starting over like it were a new phone would fix the issue, so I did flash_all_lock.bat, but now I'm just stuck with this weird bootloop and a locked bootloader. Trying to unlock the bootloader with fastboot just gives me "oem unlock is not allowed", so I'm at a loss here.
Does anyone know of anything else I could do, or is this a hard brick?

With a locked bootloader EDL flash probably is your last chance.

I got stuck with a similar problem and that was the only option, to boot into EDL mode you will need to partially dissasemble your device and flash the image via fastboot or via MiFlash (download the latest version as I had problems with an older one). Since that incident I kept the bootloader unlocked just in case something happens.

I had the phone booted into EDL mode and attempted to flash the stock ROM (10.0.3.0) with MiFlash, but it errored out with an ERROR_UNSUPPORTED_TYPE. I tried with the previous version, 10.0.2.0 and it worked for some reason. That fixed it though, so thanks! I've been lightly tinkering with rooting android phones a few years now, but until encountering this issue, I'd never heard of EDL mode. You learn something new every day? ?

I have the same issue with my nephew 's mi a2 lite which has the bootloader locked.
It only shows the android one logo.
I cannot go to recovery mode, but I can go in fastboot.
Changing from "a" to "b" doesn't solve anything and being the bootloader locked is not possible to flash anything from fastboot.
So I've opened the device and I've short circuited the edl pinpoint to be able to flash with MiTool (I've used an old version since more recent ones gave errors when flashing).
I was able to flash both the latest official ROM and the oldest one which I've found ( daisy_global_images_V11.0.14.0.QDLMIXM_10.0 and daisy_global_images_V9.6.4.0.ODLMIFF_8.1 respectively).
In both cases the device still is "frozen" with the android one logo when I've tried to turn it on after the flashing procedures gave me a successful status.
What else can I do?

Mi A2 Lite reboot loop

I was trying to flash vanilla AOSP GSI and everything was going as expected.
After that, I flashed "disable force encryption" and the fingerprint gestures files among with magisk and pico gapps and the phone started rebooting after a single freeze of 2 or 3 seconds right after the initial boot.
Actually I made several tries with different combinations trying to figure out what was causing that behaviour and I noticed that it used to happen patching "fstab.qcom" file in "/vendor/etc" path as stated in this guide, always keeping a backup of the original "fstab.qcom".
At some point my device started rebooting even after restoring the old "fstab.qcom" so I flashed the stock rom via fastboot but it didn't solve the problem, then I also tried to flash in edl mode (enabled with "fastboot oem edl") but no way, the phone keeps rebooting without letting me finish even the initial setup.
I can access fastboot, edl and recovery. I can also flash TWRP but I can't turn off the phone.
I don't know what else to do, please help me
Sorry for me being a big noob and for my unclear english.

[Help] Oneplus 7T Qualcomm CrashDump Mode

Today I flashed the newest OOS 10.0.3. After I had flashed it+TWRP through Magisk and rebooted, Vanced Youtube was not able to be installed correctly. I have fixed this earlier by uninstalling the Youtube app through a root-uninstaller app. Then flash Vanced in Magisk, and reboot.
After doing this, my phone would only bootloop into TWRP/Fastboot. So I tried to boot into TWRP, flash OOS 10.0.3, TWRP then Magisk, in TWRP, but no success. The phone would just bootloop. So I tried my final attempt without having to wipe the whole phone - Flash an old backup (I think it was from October, probably OOS 10.0.1). After doing a full recovery in TWRP with the old backup, my phone boots into Qualcomm CrashDump Mode with a message displaying
dm-verity device corrupted Force Dump
Kernel_restart

By holding power+volume up for 10 seconds, my phone reboots displaying the warning message about my phone's bootloader being unlocked, then shows the quoted message above.
Could anyone please help me fix this?

Update:
So after trying to reboot for 15+ times, my phone somehow booted into TWRP. What would be the best step now?
Wipe all, flash OOS 10.0.3, Flash TWRP and Flash Magisk?

Which specific model do you have, region? Which twrp was used?

Oneplus 7T Qualcomm CrashDump Mode
Hi Everyone,
My OnePlus 7T got stuck in QUALCOMM CRASHDUMP MODE.
First, i wanted to know the reason why this crash is happening as i can see many users reporting the same in many forums.
Note : It is my brand new phone purchased 2 days back.
Thanks !!

Restor your firmware with the msmtool

Here are the drivers that are installed on my PC ( I enabled hidden devices, in order to see them ) These were recognizing prior to " qualcomm crash dump" .
Now ADB,Fastbootd and Windows 10 / Mac OSx do not see my device, let alone recognize

It's possible that your phone is corrupted. Double freezer bag phone, express all excess air out from bag, zip both bags tightly, stick phone in freezer for 1 hr to deplete battery, then try buttons and msmtool

Question Weird brick

Hello,
I'm facing a bit of a weird situation with my K20 Pro. I just went to update it after a long time ( unlocked bootloader, TWRP and custom rom Revolution X). At the moment of installing, it was usually going to TWRP and rebooting and all good, this time, no. Just black screen. And since then, it's stuck in bootloop, and whenever i try to access recovery mode it just crashes. I tried to reinstall twrp trough fastboot but the same is hapenning.
I tried to flash the OEM OS too trough miflash but after 0s is says '' success '' but as you could guess it : nothing.
I already had others soft bricks on other phones but nothing like this, if anyone has a guess ?

Update : Could access TWRP for the first time after trying again to flash the official rom
+ now says that no OS is installed (

[SOLVED] Trying to unbrick phone from "This MIUI version can't be installed on this device" after failed OFFICIAL OS update.

I have a bricked Redmi Note 5 Pro. Stock firmware, locked bootloader, did literally nothing that would cause this. Just updated firmware (it happened few years ago, just now decided to try and repair it), and after update It's stuck in Mi-Recovery 3.0, with options only for "Reboot", "Wipe Data" and "Connect with MIAssistant", with red text at the bottom "This MIUI version can't be installed on this device" (see photo). Tried everything form this menu, nothing solves the problem. I can boot into fastboot but can't use it as the bootloader is locked and debugging is off. I can go into EDL mode but can't flash as I need to log in into Mi Account, and my sister (this phone was hers) forgot the password and even the account which was connected to this device. I was looking for MiFlash that bypasses authorization but can't find any that is not marked as malware (anyone knows of any that is safe?). At was past the warranty and I've tried to ask few phone-repair shops but the said that is unrepairable.
Any ideas what I can check or try next to solve this problem?
BTW. Does anyone knows why all of this happened? As I already said, never did anything with OS, only updated it which caused brick. My only idea is, as this phone was bought not from official store, that it might be a phone that was bought cheaper in china, then flashed with modified global OS and after update it was replaced with official global OS which bricked the phone. No idea if something like this is possible.
Edit [Sep 19, 2021]: I got somewhere. Used Firehose file to flash whyred global image without authenitcation. Got into system. I can at least go into fastboot and it's detected correctly in windows. Now I'm trying to get root, flash TWRP and any non-stock OS. Couldn't flash directly via fastboot because of anti-rollback check. Tried to do "fastboot boot twrp_rn5pro.img" which resulted in FAIL in console (status read failed - too many links) and "The system has been destroyed - click the power button to shutdown".
Edit2 [Sep 19, 2021]: Looks like my bootloader is still locked and that's why I can't flash custom recovery. But when I look in the phone settings it says that my phone is already unlocked. Checking in fastboot via PC says otherwise. Enabled OEM unlocking, but fastboot still says "FAILED (remote: Token Verify Failed, Reboot the device". Can't unlock it using MiUnlock cause they say that I need to set my account as available to unlock in unlock status on my device, but I can't do it as my device says that it's already unlocked.
Edit3 [Sep 20, 2021]: I've tried other tool: XiaoMiTool V2 (by Francesco Tescari). As the option "My device works normally I want to mod it" didn't work I chose "My device is bricked I want to unbrick it". Selected option without unlocking bootloader (wouldn't work). And it actually auto-detected that it's chinese phone and flashed chinese OS (MIUI 10.3 Stable). At the boot I got a prompt that this device is locked and I need to log into my Mi account (the one I logged in in the last ROM - from first Edit), after logging in it let me go through setup (luckily there was English). But phone still says that it's unlocked while it's still locked in fastboot. So in the end it didn't got me anywhere, but at least I know that orginally it was a chinese phone.
Edit4 [Sep 20, 2021]: Finally solved the problem! Used this tutorial. Did everything like shown on video and at the end I have MIUI 12 with unlocked bootloader (this time it's actually unlocked - checked with fastboot). Managed to flash TWRP using dummy.img and flashing to recovery. Couldn't boot from img, but vol+ + power did the job. With working recovery I can do everything else I wanted to do.

I had the same issue, which I also managed to fix. I thought I'd share what I did here.
My phone was bricked with access to MIUI recovery and Fastboot. My phone was locked, however my phone was not linked to my Mi account, and so I couldn't unlock it using the Mi Unlock tool. The only way to get into EDL mode was via the testpoint method. It's not as scary as people may think.
Many of the YouTube videos on testpoint show that you have to touch the two terminals while pushing the cable into the phone. Several times I was able to activate EDL mode without doing both at the same time - i.e. I could just connect the cable and touch the two terminals (I used a paper clip) and the phone would enter EDL mode. I think it might have had something to do with me pressing the power button. In my case, I had to have the battery disconnected from the circuit to get into EDL mode.
I used the Xiaomi Flash tool. Always remember to select not to relock the bootloader. I think it's stupid that relocking is the default option and that the radio buttons are at the bottom of the program and sometimes not visible on a laptop. That's how I got into this mess in the first place!
One of the things that I think causes the "MIUI version" problem is attempting to install the incorrect stock ROM. The phones may be fussy about which stock ROM they will accept. In my case, I thought the phone was a global version, then worked out that it was probably a Chinese version.
I replaced the firehose files in all the ROMs I attempted flashing with the ones supplied on XDA. The Xiaomi Flash tool reported success several times, but when starting up the phone it would go into recovery with the "MIUI version" message. I tried about six different MIUI ROMs with the testpoint method, both global and Chinese, before stumbling on the one that worked (after replacing the firehose files): whyred_images_V11.0.2.0.PEICNXM_20191023.0000.00_9.0_cn
When I got back into MIUI, I linked the phone to my MI account and then attempted flashing the latest LineageOS (which was what I was trying to do in the first place), using the Lineage recovery. The phone wasn't accepting the Lineage recovery, so I flashed OrangeFox-R11.0-Stable-whyred. I had to boot to Orangefox in order to flash it. You copy the Orangefox zip file to your phone using your computer when you have MIUI up and running, then you enter Fastboot and run the following command from your computer:
fastboot boot recovery.img
From Orangefox, you then select the Orangefox zip file on your phone and swipe to install.
Once that was done, I rebooted to recovery and did a wipe of the phone. It wasn't enough for me to wipe Dalvik/ ART Cache and Cache (as recommended), I had to also wipe System, Vendor and Data. (I tried just the first two and the LOS installation was corrupt, even though it was reported as being successful.) I then copied LOS to a micro SD card, inserted it into the phone and mounted it, before flashing LOS by navigating to the zip file on the SD card, selecting it and selecting wipe to install.
Finally success!
I think the key with the testpoint method is to keep trying ROMs until you stumble on the one that works. If the Xiaomi Flash tool reports success, I think it means you are doing something right. I also wonder if a lot of people who have the "MIUI version" issue have a phone with the Chinese ROM and don't realise it.
Hope this helped someone!

by any chances how do you unlock bootloader if you just bypass the mi account?

the reason is I got my phone Redmi Note 5 Pro on fb marketplace by swapping my old phone, when I'm using it there's no mi account logged in on my phone then I tried to install the latest MIUI 12 by flashing it on MiFlash but I didn't notice that I didn't change the setting on clean all so it locked my bootloader, after I manage to fix the issue about my phone because it doesn't open and it only boot on recovery with a message "This MIUI...." and make it boot by flashing cn official rom, it says that my phone is locked and I need to logged in the old mi account, I already ask the previous owner but he said he doesn't have an access on that account, even the number and email are already lost

If it's locked and you haven't registered the phone with Mi Account, then you will need to use test point. There are a lot of claims that it's not necessary, but I tried many of them and it wouldn't work. I think they are a load of rubbish to get you to pay money. Test point is not that hard, but you need to pick the right ROM.
