Warning - Own Risk!
requirements:
- systemless root
- unlocked bootloader
- TWRP
After downloading the update from Lenovo, the update is stored in the /data/data/com/lenovo.ota folder on your phone.
go to shell in adb and request su priviliges to copy the OTA update to your sdcard folder.
Download zip file and edit the updater-script file found in META-INF\com\google\android folder
Look for line 6
Code:
getprop("ro.product.device") == "[B]P[/B]2a42" || abort("E3004: This package is for \"P2a42\" devices; this is a \"" + getprop("ro.product.device") + "\".");
change
P2a42 to
p2a42
save and copy updater-script back into the META-INF\com\google\android folder of update.
rename zip file to OTA-TWRP or whatever you prefer and in adb push the update to your sdcard.
reboot to recovery and disable zip verification in options menu and flash OTA-TWRP. Some red errors show. after flashing wipe cache and reboot.
Your are now on android 7.0
Recovery is replaced by stock lenovo recovery. Root is also gone.
I am now fastbooting TWRP in order to backup boot and system and flash SuperSu.
update: Backup worked, TWRP is installed and device is rooted with newest SuperSu app. root verifier says i'm not rooted.
