This is TeamWin Recovery Project version 220.127.116.11 for Lenovo Ideatab A2109. twrp-recovery-18.104.22.168-20160303.img (MD5: bc56af770828092271fd92d11021bbcc) Sources are in the cm-12.1-twrp branch of my device tree on github This is a very nice recovery with more functionality than cwm. Note that cwm backups appear to be incompatible with twrp! To install, reboot to fastboot and use fastboot to flash the recovery image. On Linux: Code: fastboot -i 0x17ef flash recovery twrp-recovery-22.214.171.124-20160303.img Basics for installation (how to boot to fastboot, etc.) are over here: [HOW TO] Install ClockworkMod Recovery and Root | Android Tablet Forum Unlock A2109 Boot Loader with Ubuntu | Android Tablet Forum I've tested the usual functionality myself (backup, restore, adb sideload, installing zips) and a few other bits and all appears to work fine.
