hey, I happened to have the exact same problem on the Mi2. Not sure why does the different partition cause an issue now. Anyways, can you please please please post the exact steps you followed for recovery? Let it be a noob step too, we can save time over questions. Did you lose your data during the process? What is a ZTEMT?
Thanks much & appreciate your help!
Hi,
ZTEMT is a utility from ZTE that can be used to flash Qualcomm based phones under QDloader or QDiag mode.
Yes, I lost all of my data in the process and also my IMEI and BT MAC.
On 2nd thought, if you desperately want your data, you can try to dump the partition using dd, mount it on your PC, and scan it with file-recovery software... I didn't try it...
When the IMEI (EFS partitions) is lost, the phone will boot 1st time after ~20 minutes, and then will not boot again most of the times. if it will boot again, it will be buggy and stucky...
I have 7 Mi2S in my family, two of them nearly-bricked after the update, in the other 5 I did the upgrade step by step after backing up all the data.
steps:
1. backup the EFS partitions (

2. turn on the phone under qdloader mode
3. open MiFlash-2012-11-06 or ZTEMT, and flash the latest fastboot version on the device (
http://www.google.com/url?q=http://...sntz=1&usg=AFQjCNEuFIvBaSj2ize5pr-fE7XnJDBxSw) - it will build the new partition structure and flash the image to the phone.
4. after flashing completed successfully , reboot the phone into fastboot mode and install CWM recovery (with TWRP you cant access via adb...)
5. Boot into recovery mode and dd back the EFS partitions via adb.
6. reboot to fastboot mode and install the original recovery back.
7. reboot the phone and wait about 10 minutes for 1st init and startup.
8. if the phone not booting after 10 minutes (happened to me one time...), start it in fastboot mode, and flash again the same fastboot image using MiFlash-2012-11-06 (NOT ZTEMT) - it will use the new partition structure.
9. if you want a multi version, download it to the phone, rename it to update.zip, install it via recovery. (be sure to wipe all right after) - wait 10 more minutes for 1st init and startup (again
)
I hope I didn't miss any step...
of course, everything you do is
at your own risk.
Good luck!
