My Xiaomi Mi2 imei and baseband are invalid (unknown), probably because of some flashing...I need that somebody shares his .qcn file of Xiaomi Mi 2 to solve my problem (i am gonna use my imei, i still have it from the mi2 box). You can create a .qcn file with qpst very easily.

To backup your QCN, HIGHLY RECOMMENDED so that you don't corrupt your QCN data like i did, simply follow the guide at android brick below (http://www.androidbrick.com/ultimate-guide-qualcomm-snapdragon-xiaomi-mi5-imei-and-baseband-repair-fix/)

Summary
  • Install all the stuff per the guide. (if you have been flashing your phone with QPST already you probably already have)
  • Open QPST Configuration > go to ports tab > there should be already one port with the phone (if no,add new port) > press OK
  • Open QPST Software download > Make sure the correct port is selected > go to backup tab > choose the directory you want it saved in > Click start
  • Share it with me.... Please.......
qpst: https://www.androidfilehost.com/?fid=24591020540824930

diag driver: https://mega.nz/#!CZFTVJYS!lvBK0RlWKPIMHQjbeNrzBulcBqTtqBGqaBBiGv2gpyE

optional (if you don't have adb in your pc): https://www.androidfilehost.com/?fid=24591020540824933

You can pm me if you can help me

I can help you as soon as I replace my USB port. Currently It's half-broken. Since I'm ordering it from China, I don't know how long it will take to replace it. Hopefully someone can help you sooner, but if not I can do it for you.

if you proper enter the diag mod and qpst recognizes the phone, it should be working

btw I sent you a private message

maybe it's not doable...try to give this command (it's just to see your partition table):

adb shell
su
ls -l /dev/block/platform/msm_sdcc.1/by-name/

Is it necessary the phone is running MIUI? Or is it possible, that it will work on CM 12.1?

as far as i remember it's not working with custom rom...try to enter diag mode, there are 2 ways:

1) dial pad: *#*#717717#*#*

2)terminal (cmd on windows):

adb shell

su

setprop sys.usb.config diag,adb

Then you need to install some driver (qualcomm qpst diag driver) and finally you can use qpst program (qpst-->start clients-->software download-->backup)

EDIT it's working also on CM 12.1. You just need root access to adb in developer options and then you can use the command (second option above)

Cool. I found a seller for the USB port, that is from my country, so I could hopefully get my phone fixed sooner than I expected.

unfortunately the one @Porske passed to me is not for mi2 but for mi2s...check under your battery, there's a sign:

mi2 - 2012061
mi2s - 2013012

it should be the different chipset the problem with the restoring (it seems to work from qpst but when i reboot the phone there is no imei and baseband)

PS porske is the only guy who managed to perform the backup, probably because he was using a miui based rom

I was just about to say that i run cm 12.1 so probably that's the problem and then saw that you got mi2 so there is no point trying with miui since i have mi2s :(
