How to enter flash mode

To start fastboot mode:

  1. boot into recovery by holding volume-down while starting the device, then
  2. adb reboot bootloader

To unlock bootloader in fastboot mode (CAUTION: this will erase userdata! Backup before doing this!): fastboot oem unlock

Installation

My procedure was:

  1. Backup all important user data
  2. Unlock bootloader (see above)
  3. Install CWM recovery by going into fastboot mode and then running fastboot flash recovery A2109_CWMrecovery-6.0.1.9d.img
  4. Backup Android installation on SD card
  5. Follow installation guide (note that flashing rootfs can take a few minutes without feedback, just wait)
