Mi5 Bootloop with unfortunate circumstances :(

My Xiaomi Mi5 which has the misfortune of getting into BOOTLOOP
Here's some info regarding the device:
1. The bootloader is locked.
2. I forgot the assigned MI account
3. Developer mode is NOT on
4. USB debugging is NOT on
5. I can get into fastboot and recovery mode
6. I have tried using Chinese mi pc suite to flash a new rom, but it doesn't work
7. I have no further info regarding this device
Is there anyone out there who can help this poor soul? Is there any complete guide to fix this situation?

The only thing you can do in a situation like that is flash a MiUI ROM using Mi Flash, try uing EDL. You can enter it with fastboot oem edl
But even if the device does boot up you'll still face a lock requiring the original mi account login and password to unlock the phone.

flash official miui fastboot rom. something like this

no need of bootloader unlock, no need any debugging setting, it will be easily recoverable.

MI 8 - Bricked

Hello,
I was running unlocked bootloader and pixelexperience rom. Today I wanted to try to flash latest xiaomi.eu and now my phone is bricked.
Steps:
Twrp -
flashed data (after that i saw that i had an error and data didn't flash)
installed rom (because i didn't see the error) - rom failed to install
flashed data again from twrp advanced option
phone rebooted and now it bootloops on mi logo. i do not have recovery nor fastboot.
what can I do in this situation? i searched the forum but there is nothing similar

You must have fastboot, check how install miui using mi flash. I use this method and working for me

When I try to boot into fastboot, it only shows black screen. The PC does not recognise it.
Also, I do not have EDL mode available..

Exact same issue, no fastboot or EDL mode. Tried updating the latest Miui 11 - Android 10 - Xiaomi EU Rom (Jan 25th) and the phone has been bricked.

Solution Deleted.

got into EDL mode using test points, but now i have edl auth error - "cannot receive hello packet"
Seems like a common problem for bricked devices and need mi account with the right edl auth privileges.
Any help welcome.

There is nothing to do, unless:
A) you find a Xiaomi Authorized account (in which case please alert us)
B) you manage to hack the EDL mode and bypass the Authorization.
Tertium non datur.
EDIT: EDL is the only chance for you anyway @Andrei221
If you had fastboot you could get into EDL by running: "fastboot oem edl", but since you have no fastboot you're only left with the test-points or an EDL-cable.

No. I've tried different things:
- trying to flash with QPST in EDL mode (9008)
- trying to flash fastboot roms with various/ancient versions of MiFlash in EDL mode (9008)
- flashing standalone modem firmwares (old ones, new ones, non-ARB ones, packed with NON-HLOS, etc.) from TWRP
- doing a MITM on the response that MiFlash & MiFlash PRO get from https://update.miui.com/updates/miotaV3.php
- doing a MITM on MiFlash and redirecting requests to old URLs (https://update.miui.com/updates/miotaV2.php, https://update.miui.com/updates/miota.php) and black-box testing them
- using MobileEdit Forensic tool to exploit the EDL firmware
*Note*: I've obviously tried all the different FireHose programmers that are floating around (including those distributed by MobileEdit).
Nothing works.
Especially trying to modify the response (if one understood its format) could very well be useless because it could be that the response from update.miui.com is validated directly by the firmware itself (like a challenge-response authentication) - this has to be verified.
The only possibility I see for now is to flash the original Xiaomi Recovery, let it connect to MiFlash Pro (choosing option n.3 from the menu), and then using IdaPro to trick MiFlash Pro into telling the Recovery to flash the phone. It shouldn't be hard, and I think it *MIGHT* offer the possibility to bypass ARB & Authentication (but I might be wrong: it might be equivalent to flashing from Fastboot). That waits to be tested.
I hope this saves y'all from wasting time.

To flash or unbrick Xiaomi Mi 8 Lite, you'll need edl authentication to use the Mi Flash tool to complete this flashing operation. An authorized Service Account is required. This is the worst part of flashing the latest generation of Xiaomi android devices. I have had this problem before with MI 8 Lite. I stuck getting these error messages "Mi Flash Tool Unauthorized for this Operation - Your Account is Unauthorized for this operation - Authorized Service Account required"
This method works only for Mi 8 Lite

Redmi note 9 - EDL flash - Need authorized Mi account

Hello,
i have problem with flashing redmi note 9 pro in edl mode.
I need authorized Mi account. Can somebody help me with it? Via teamviewer? Reward certain!
Thank you very much, Lukas

Edl mode is basically service center repair from xiaomi.You need ifu dongle or contact repair center.or black market not recommended do.

This section is for MERLIN (redmi note 9).
If you want to use sp flash tool, you need to flash the stock rom preloader using V12.0.4.0 (or lower). (It will works perfectly with lower preloader binary version).
With an older preloader version, your phone will can receive DA files and accept flashing with NO auth.
Everything you need to do is plug your phone in usb (without press any key, if you press any key it will enter in EDL mode and requests authenticaion).
Here, are PRELOADER binaries for flashing: https://forum.xda-developers.com/t/...omi-redmi-10x-4g-xiaomi-redmi-note-9.4221081/
Here, are DA files for flashing using flash tool: https://forum.xda-developers.com/t/...omi-redmi-10x-4g-xiaomi-redmi-note-9.4209767/
Only after it, you can use sp flash tool again.

Do I need to flash it via fastboot ?
I have already done it but my device is detected in com ports for only 2 seconds and then charging screen appears. I have also installed device filter(libusb).
And after flashing preloader by device doesn't stay in edl mode even I connect my phone while pressing and holding vol down .

Desperately looking for Xiaomi Mi9 Cepheus No Authentication Firehose elf file to unbrick my phone

Hi everyone,
I bought a Xiaomi MI9 with 128GB of RAM supposedly brand new with an unlocked bootloader to replace my old Mi 9 with 64GB whose screen was broken after a fall. I flashed the latest version of the official EEA ROM and then, for security reasons, I made the mistake of unlocking the bootloader again with "fastboot oem lock" adb command. Since then, my phone start until the MUI logo is displayed then reboots. I have no access to anything. The only way out is to reflash a new rom in EDL mode but, to do this, I need the patched sdm855 ELF file for the mi9. I've tested the one for K20/Mi 9T which have the same name with no success. Can anyone provide me the holy grail ?
Thanks for your help.
David.

@Magellan13, Did you fix it? And how?
If it were a Samsung there would be a recovery key combo, a download mode key combo and if it were Qualcommm - EDL mode- where you would need the correct files to flash.
In recovery there would be a clear cache which can sometimes make it start.

Do u have access to fastboot by keys?, U may have to.unlock bootloader but to unlock u need have registered device on MIUI account.

Question Bricked Mi 11 Pro, need help with auth in EDL mode

I tried to install a firmware for my Xiaomi Mi 11 Pro using the Mi Flash tool, but I accidentally left the option to lock the bootloader again selected. But when trying to start the system, the device says that Miui is not compatible with my device.
Then I tried to use Miui Unlock, I even manage to log in with my miui account, but the procedure is interrupted and says that to continue with the bootloader unlock I need to do some steps in the system, but I no longer have access to the device's system.
But I managed to open the device and put it in EDL mode, but it asks for miui account authorization. What I have to do? Or someone would it have the unlocked file, the firehose for the mi 11 pro?

AFAIK there's no patched firehose for Mi 11 series.
You need to find paid EDL flash service.
Search in Telegram .
