Instructions for backup and recovery IMEI from the created backup
What do you need:
- QPST
- Qualcomm driver
- ADB + driver
- The installed firmware with root access
- Straight arms!
Let's start.
You need to enable developer mode and debugging via USB.
If we have everything from the list "What you need" is installed, then we go further if not - set.
For backup needAfter installing the programs, you need to translate the phone to the diagnostic mode via ADB. We perform the following commands (tissue with accurate not to enter! You can enter commands through the terminal on Android, then the first command does not need to be entered):
1. adb shell
2. SU (at this time I look at the screen, because during the second team you need to provide root rights)
3. SetProp SYS.USB.config Diag, RMNET, ADB (commands 3-4 to choose from, depends on the firmware, if Qualcomm HS-USB Diag appears in the device manager, then you do not need another mouse!)
4. Setprop sys.usb.config Diag, ACM_SMD, ACM_TTY, RMNET_BAM, MASS_STORAGE, ADB
In Device Manager, the device appears - com port: Qualcomm HS-USB Android DIAG 901D
Now go to the installation folder QPST (standard C: \ Program Files (x86) \ Qualcomm \ QPST \ bin) and run QPSTConfig.exe add our COM port (add new port and type in both points (Port and Port Label) port that It is written in the device Manager)
Later in the same program, click Start Client ->Software download. Go to the Backup tab, select the folder where we save the file, the file type is better to choose QCN. Click the Start button, after completing the START button will be active again, it means our backup created!
For recovery needMake the same, but in the Software Download program window, go to the recovery tab, select the file of our backup, put the Allow Phone / File Esn Missmatch tick and press the START button.
Reboot the hardware components, check the IMEI.
Is done

XQCN file from the Chinese Forum. Thanks say to him
ZUK Z2 - Firmware (Post Polumish # 53951755)666666.RAR.(130.08 KB)
If you can't restore the XQCN file, the "Recieved Invalid Command From Phone" error appears. Need to:
Make a backup FSG, Modemst1, Modemst2 via ADB Shell (need root rights, and it is better to do in TWRP, not needed there):
adb shell
dd if = / dev / block / bootdevice / by-name / modemst1 of = / sdcard / modemst1.img
dd if = / dev / block / bootdevice / by-name / modemst2 of = / sdcard / modemst2.img
DD if = / dev / block / bootdevice / BY-NAME / FSG OF = / SDCARD / FSG.IMG
Save on the computer files Modemst1.img, modemst2.img, fsg.img, which, after executing commands, will appear in the phone's memory.
After that, make sure these sections:
dd if = / dev / zero of = / dev / block / bootdevice / by-name / modemst1
dd if = / dev / zero of = / dev / block / bootdevice / by-name / modemst2
dd if = / dev / zero of = / dev / block / bootdevice / by-name / fsg
Enable the phone, pour the XQCN file, restart, check IMEI. If IMEI is there, then restore your IMEI according to the instructions
