Bricked Mi3 - Showing QHUSUB Bulk in PC

I installed the latest 12.24 alpha version (http://bigota.d.miui.com/5.12.24/miui_MI3WMI4WAlpha_5.12.24_1e8fc7c2ed_6.0.zip) of MIUI 7 - MM (someone posted link on CM13 thread: http://forum.xda-developers.com/showpost.php?p=64500712&postcount=154)
I was on extended partition before. Everything succesfully got flashed in TWRP. But after rebooting system, phone died.
Connecting to PC I can see the device as QHUSUB (might have misspelled) and can see lots of drives connected (which it asks to format to use, which I won't as it ends up badly)
Any solution now? Otherwise like last time it got bricked, I will wait a day to battery get drained and than possibly hope for Fastboot to come back though I believe this issue can be fixed via PC only, not sure.
And I guess it got bricked due to extended partition as the ZIP probably merges both System.

Don't worry have you backup you data?
if you have, just install the driver for qhusb
then your phone should be able to recognises by MIflash then flash any fastboot rom, You phone should be good to go.

I had a similar issue but i tried to hold the power button for like 30 seconds and the phone booted. If it didn't work, you should follow this thread: en.miui.com/forum.php?mod=viewthread&tid=73348&highlight=Mi3%2Bunbrick&mobile=no

partition error
u must download fastboot rom this link : http://en.miui.com/a-234.html > Xiaomi Mi 4 CDMA/WCDMA/LTE Latest Global Stable Version Fastboot File Download

Did you personally tried that? Because flash all bat do uses fastboot to flash, which can't be accessed.
I wonder whether the other one u poster doesn't use fastboot, cant check the file content atm

I have tried many times
last times tried 3 hours ago, for alpha 5.12.24
my video under explain
http://m.youtube.com/watch?v=fSl9xrR_J4g

@murattiy that flash file didn't help either as it was based upon fastboot
But, the device was directly detected in MiFlash and simple flashing made it run lol

you need to do İnstall spacial flash_all.batt change to in flash_all.batt "cancro_global_images_V7.0.5.0.KXDMICI_20151016.0000.3_4.4_global"
dont use miFlash .. enough u clik speical flash_all.batt

If your device not boot into fastboot/recovery mode press power button for around 30-40 seconds .

and still not boot into fastboot/recovery mode
battery cable exist than try.. i tried many times))

Xiaomi Mi5 Bootloop, no recovery mode, no edl mode, only fastboot

Hello everyone ... I have a xiaomi mi5 in bootloop.
- Initial ROM fake seller (learned later)
- I tried to update with MiPcSuite and is now in bootloop.
- I DO NOT unlocked bootloader
- I did NOT access Xiaomi account on mi5 (so I can not unlock it now even if I have permission from Xiomi)
- First of all, I activated the "developer mode" and "USB debugging".
- I can only enter Fastboot mode
-I Can not use the recovery mode
- I can not get into EDL in any way: no adb, no tool here (with the tool says restarting EDL success but restarts and reappears MIUI logo, does not turn on the red light and nothing appears in the device manager)
Thank you

Try to wipe system and install
1. Go to fast boot.
2. Wipe all partitions
Code:
> fastboot erase boot
> fastboot erase recovery
> fastboot erase system -w
flash fresh fastboot image from Mi
Code:
>fastboot flash system <image name>

It works? It has already been tested? I could not find any other guide that told you to do this ... I will not say that I do not trust this, but I want to do other s-h-i-t! I remember that I have the bootloader locked, and I can not go to EDL mode ... thank's

Not sure you are allowed to run the flash command when you're on locked bootloader. I'd try it without erasing, since flashing overwrites the partition in question anyway.

I have experience like you... Get bootloop.
But when I wipe/erase all of internal memory through Mi PCSuite China version, it's boot normally and MiUI8 started.
I tried the same method to apply the official china stable rom on my friend Mi5, it's bootloop... Then when I wipe all, it's boot normally.
Hope this will help you...

how do you wipe using mi pcsuite? which button did you used?

I think 3rd button..
You can get help from Google translate app.
Take photo from Google Translate then translate to your language.

Use the Chinese mi pcsuite if the English one doesn't recognize the phone. I am not sure if you cannot enter in any form of recovery you have luck with that though.
Fastboot and miflash that was suggested will not work with locked bootloader.
Your best and last bet is to use EDL mode. The issue with Mi5 is that it doesn't go easily in EDL mode. not with key combo at least. Have you tried this? https://forum.xda-developers.com/an.../guide-how-to-reboot-to-edl-fastboot-t3394292. Otherwise, check for deep flash cable or make one yourself.

in lineage's Usermanual it says after a few steps:
Hold Volume Up and Power buttons simultaneously. Continue to hold both buttons until the “MI” logo appears on the screen, then release.
I get only fastboot-image nothing else.
i did the following comands:
> fastboot erase boot
> fastboot erase recovery
> fastboot erase system -w
>fastboot flash recovery recovery twrp-3.1.1-0-gemini.img
Both Power and + or Power and - : Same result: Fastboot.
I had unlocked the phone and usb-debugging was enabled.
I do use Linux by the way

Hey, did you solve it? I have same problem and I'm desperate

No I didn't solve the problem. I realized that I completely was wrong. I had an Xiaomi Mi 5c in stead of Xiaomi Mi 5.
I finally was able to flash it because I choses the wrong Recovery and Rom.
Then I sold it and bought a Xiaomi Mi 5 which I wanted because it is supported by lineageos...
?

Hahahah what a story man, I fear I didn't choose the wrong Rom and I have a good brick :') Lineageos is just amazing, have fun!

.....And anyway, in the end I had solved it with a home-made EDL cable 3 years ago ???...and my Mi5 is still alive in my hands 3 years after ?
I had forgotten this thread
I hope you can now sleep well again at night now that you know that everything went well ?

3 - I flash in recovery mode last MIUI rom 9.5.5.0, phone still running well after that
4 - I boot in recovery and flash this firmware in order to flash Clarity Kernel after
5 - After flashing the firmware I reboot and Im stuck at MIUI logo. I can go to fastboot mode though. But unable to reach recovery mode neither switch off the phone.
6 - I install MiFlash and tried to flash different version of rom MIUI santoni from official website (9.5.5.0 / 8.2.10.0) neither work SEE IMAGE I tried with mi flash 2016.08.30 same result
I get different status on mi flash, one is (image not matching device), even though I think I did everything well.

Well i am not at all an expert in miui, infact this is my first mi phone. But i think this tool called xiaomi adb/fastboot tool can help u. Google it.... It is available in reddit. One piece of general advice : before any kind of experiment always keep a preparation for the worst case scenario. I think ur phone is stuck at boot. U can try to hold the power button for about 10-15 seconds to turn off. Also just relax and have patience... It will b solved. Let me know how it goes.

Nevermind I misread... If you think clarity or the firmware messed up your phone I could give you my kernel and firmware for you to restore it
Though if you're desperate for a solution, I'd transfer a ROM into your phone and start over with it, you can flash MIUI also by flashing https://drive.google.com/file/d/0ByWEieei-0nyMTR4R0dxWk9BTms/view after it

Your version of miflash is a little bit outdated! The last One is from may, last year if my memory doesnt fail. Install latest version of miflash and try to flash again stock ROM.
You can try also flashing stock ROM with miflash but in edl mode (emergency download mode) , instead of fastboot mode, but to do that you have to acess stock recovery, and then use this command " adb reboot edl", connect your phone to PC, and then see of detects, then flash then stock ROM. To acess stock recovery, press volume up + Power, if that not works, press volume up + volume down+ Power. Hope i helped

Ok I solved the problem using this method.
So I removed back cover, disconnected battery, connected the 2 points with a twizzer then flashed STOCK rom and it worked!! So relieved!
Thank you for the help anyway.

You can checkout tutorials on using SP Flash tool to flash stock firmware, or I can explain when I get home. Also use spflash tool with MTK auth bypass or you won't be able to flash.

Had a pretty bad month as I completely killed my phones software. Heck I even deleted the preloader which is the core responsible thing for a mediatek chip based phone to boot. BUT SP flash tool saved the day.

No way to know what parts are missing. You can reflash your current ROM or the original ROM via fastboot.

If your bootloader was unlocked you can recover the device via fastboot.
If not you have the same situation as described here:
Redmi Note 10 pro stuck on Mi logo loop after update
I tried wiping my data, but no success. I tried mi flash tool but no scucces. My bootloader is lock. I can boot into fastboot and recovery mode only. Safe mode also loop into logo only. can anyone tell how i can flash stable rom.
forum.xda-developers.com
Interesting to see that several people are reporting bootloop after upgrading to MIUI 14.
My advice to anyone is to unlock the bootloader before upgrading to MIUI 14 to avoid having a brick, which you can't recover by your own by just flashing.

Thank you.
But could you please explain what you mean with "waiting"?
I assume that you mean the seven days until Xiaomi grants you the possibility to unlock the bootloader, right?

I agree with regards to this device.
But usually it is not a problem.
With regards to this device I see from two other people that they are facing a bootloop when updating to MIUI 14.
I also did the update and my device ended up in a bootloop.
But I had unlocked the bootloader in advance and could recover the device by flashing.

Hi
Greetings, I am facing the same problem, after upgrade to miui14 the phone is in bootloop,
Explanation
1) The phone starts and enters menu(reboot, wipe data, connect with MI assistant, safe mode)
2) If i click reboot, it will reboot and reach to welcome screen and then it will ask me to activate the phone
Thats it
Then it restarts automatically
This process repeats untill battery drain
The phone is not unlocked
Advice .........

That is actually very easy. There is a tool. Mi_Unlock-en-5.5.224.24. you will need to- (a) go into fastboot mode(Switch on by pressing power+volume down) (b) Connect phone via USB Cable. Have the proper drivers installed. (c) Launch Mi Unlock tool and login into Mi Account. (d) refresh to search phone, select and press unlock. Takes a couple of seconds to unlock the bootloader.

Unlock the bootloader by following the solution described above .
Download and install MiFlashtool 2017.4.25.0.
Download a stable fastboot ROM suitable for your device and place the unzipped folder in the same folder as MiFlashtool C:\xiaomi\XiaoMiFlash
Boot device into fastboot mode and connect.
Flash the ROM. Just it.
