    Hi @ all!

    Is there special routine necessary?

    1.) Android recovery mode
    2.) CWM:
    2a) wipe /sdcard
    2b) mount /external_sd
    2c) install zip for external_sd
    2d) A2109_A411_03_13_121127.zip

    lock bootloader?

    thx in advance

    1. Flash this in CWM https://docs.google.com/open?id=0BxNORR1JMMjZd3FWQ2hndTgwcGs
    2. Flash this the same way you flash a recovery. (fastboot flash recovery A2109_stockrecovery.img) https://docs.google.com/open?id=0BxNORR1JMMjZRUVienlNZ3BKWTg
    It's explained here http://www.androidtablets.net/forum...8-how-install-clockworkmod-recovery-root.html
    3. To lock the bootloader do this : http://www.androidtablets.net/forum...52434-howto-unlocking-bootloader-windows.html but use fastboot oem lock instead of fastboot oem unlock
    :)
