Mi2s stopped working (bricked?)

[devl82]

Hello 2 all,
my new mi2s (flashed with unofficial miui rom about a month ago + updated via weekly updates) stopped working...

Unfortunately i do not know if it happened due to low battery or suddenly shut down (it was unattended for several hours).

The thing is that i can not open it/recharge it/fast boot it (volume down and power button) nor my pc (windows 7) recognizes it (even the led does not turn on).

What do you suggest??
Thank you

*update* mobile recognized without battery ('QHSUSB_DLOAD' see here in case you have same problem:: http://xiaomi.eu/community/threads/ultimate-cure-to-the-qhsusb_dload-of-mi2-s.20567/)

**update** unfortunately i cannot flash anymore (miflash 2.11.6 with 3.11.22fastboot4.1 & 3.6.28fastboot4.1).

I successfully installed driver for QHSUSB_DLOAD (downloaded from the same thread)

and suddenly while flashing this::

but i had already booted with this option!!

Anyway(s) i attached the miflash log (i didnt do wipe all -tried the other options)

Further comments much appreciated & thanks

If your battery has decharged to 0%
Take our the battery out and wait a minute then put it back in and then charge it

Thanks for your reply, but the phone does not charge... I found a guide that suggests a short circuit between battery & SIM, does anyone think this is relevant to my problem?

Any suggestion would be helpful..
Thank you for your time

Your phone doesn't charge? That sounds like a battery/usb cable problem and not a problem with your phone itself.

just tried another usb cable with no luck...
Phone does not charge, screen remains blank

Thank you for the suggestion DeepSpace

*update*
i managed, after connecting mi2s to pc without battery, to recognize it as QHSUSB_DLOAD, which leads to this

Still no charging, but i believe my best bet is to follow the instructions above and flash it again..

Am i in the right path?? {a little bit of encouragement is requested }

That problem is because of MiFlash Tool driver installation error.
I assume you are using a 64 bit version of windows OS.
First disable signature verification & then boot .
Then you try flashing using MiFlash.
Everything will be fine. You were in a hurry to perform recovery of your Xiaomi soon after your phone got detected i guess. hence without reboot after driver installation, you tried this restoration method.

Don't worry, Xiaomi phones are very hard to brick... almost never. OK ?
Try this & get back here with your results...

Thanks for your reply.
However,
i am using a 32 bit version windows 7
i have disabled signature verif (

bcdedit /set nointegritychecks ON

)
i am running miflash as admin.

& while flashing starts after a minute or so connection is lost and a red led is blinking again. Sometimes, it stops blinking and device seems connected again but in the end the msg of verification error always appears and flashing stop.

If you look at my log, after some hellos and writing this happens:

COM3 31.90 Close EMMC card USER partition
COM3 31.93 Reboot to mini kernel
COM3 32.06 Wait device connect 0

which continues until verification error (second picture i posted)

Forgive for English (google translate)
With my Mi2Sc had the same problem when discharging to 0%.
To resolve it took:
1: Remove the battery
2: Connect the phone to the charger without battery
3: usually start cell
4: Connect the battery and wait Loading
Not a problem with the ROM.

Did 1/2/3 OK
Connected battery/nothing is happening for at least 5 hours (plugged in)
Thank you for the suggestion

ok, first if your phone is in QHSUSB_DLOAD mode u are very lucky because u don't need to do the short circuit.
And the verify error means that your driver signature verification isn't really turned off. You may google for this problem because it hasn't todo anything with your phone or the miflash tool.

thank you for the response. However as i have re-installed miflash multiple times (obviously with signature verification off or i wouldnt have been able to re-install it) i am not so sure what is wrong...

Also, this happens during flashing (while flashing starts after a minute or so connection is lost and a red led is blinking again -you can see the exact moment in the miflash log). Is this normal?

I have the same problem. My Mi2s not charge and the red led light doesn't on. I tried to connect via usb to mi pc and with the charger but it doesn't work.
I have removed the phone battery and I charged with an external charger, but after the insert it in the phone and put it to charge and nothing. Everything is the same, It doesn't charge and led is turn off. Do you fixed the problem?
Sorry for my poor English.

first check if the battery is the problem:
pull out the battery and connect the charger. If the phone turns on you have to charge your battery or buy a new one if it's defect.

If it doesn't turn on you have to manually enter DLOAD mode and use MiFlash to recover your phone.

Thank you M1cha,
The battery isn't the problem. I have check it like you say.
Could you say me where I can found about DLOAD mode and MiFlash?

Thanks again.
