    Hi. I tried flashing the TWRP Recovery using a GNU/Linux PC using two methods: via the fastboot utility from the paltform-tools of the Android SDK, and via the SP Flash Tool program for Linux O.S. Both methods seems to work: the messages confirm the flashing was performed well. But when I boot in recovery mode, I get always the stock recovery (icon of died Droid, then Power + Volume UP to bring the stock Android Recovery, not the TWRP one). Some hints?

  • Niccolo Rigacci

    Finally I succeded into flashing the TWRP recovery! It seems that the trick is to reboot into recovery mode after TWRP flashing, WITHOUT ever booting in normal mode! It seems that if you boot in normal mode after TWRP flash, something restore the stock Recovery.
    So the procedure is: poweroff the phone, execute SP Flash Tool (I used the GNU/Linux 64 bit version), load the scatter file and the TWRP recovery.img, click the Download button, connect the phone with the USB cable: the flashing starts automatically and succeed in a few seconds. Unplug the USB cable, start in Select Boot Mode Menu (pressing Volume UP and Power for some seconds). Then boot directly in recovery.
    Once started TWRP recovery, I installed the SuperSU. After a couple of reboots required by SuperSU, I have a rooted phone with TWRP installed permanently on it.
