Restoring IMEI on Lenovo Phab PB1-750M

bearbeitet June 2019 in Miscellaneous
After flashing-reflashing MIUI, CyanogenMod and 750N Chinese firmwares I've lost all IMEI's.

I've edited *.inf-file from Google driver for my ADB Interface (VID_2970&PID_2282).

Entering the Diag901D mode:
adb shell
su
setprop sys.usb.config diag,adb

Launch QFIL and select QCN Backup/Restore in Tools menu.
QCN-file PB1-750M_MM_QCN.qcn is attached to the post.

    But I've thought that Diagnostics mode is "Qualcomm HS-USB Diagnostics 9006 port".
    And forced entering Phablet into diagnostics mode (rooted systemless MagiskSU/Xposed) erasing aboot and reconnect cable: "fastboot erase aboot". FACEPALM ON ME

    To return into Download mode, I've used Minitool Partition Wizard and deleted all the partitions on the Qualcomm. Rebooted into 9008 and firmware using QFIL.
  • Trying to backup NVRAM via QPST in Download mode (Qualcomm HS-USB QDLoader 9008 port) shows an error 0x80004005
  • You never can flash any firmware being in Diagnostics mode. Flashing is possible only in Download mode (9008).
