I am trying to get root access from recovery mode with the Dirty Cow exploit. I have adb access and my device is on Android 6.0.1. When I use VIKIROOT it's stuck at "waiting for reverse connect shell". I cannot open the clock/alarm app or toggle the bluetooth switch in order to trigger the backdoor. How can I root the device from recovery mode and decrypt the data (I know the passcode) of the device? Thanks.

  • Asus Zenfone 3. I am trying to use Dirty Cow as there is no other way that I know. I don't want to unlock the bootloader as it would wipe the data. –  Aug 09 '20 at 22:34

  • My device doesn't have a programmer and Kingoroot won't work on recovery mode. –  Aug 10 '20 at 08:15
  • I tried those programmers and they didn't work. A programmer is specific to a device and they need to be signed. –  Aug 10 '20 at 11:09
  • which one exactly you tried? usually signing is just vendor specific – alecxs Aug 10 '20 at 11:25

    I confirm that prog_emmc_firehose_8953_ddr_asus.mbn does not work. –  Aug 10 '20 at 14:44
  • thx for testing! too bad.. i assume you can't boot android anymore? – alecxs Aug 10 '20 at 15:36
  • Sadly, I can't. Is there any other way for me to root my device on recovery mode? I can use adb just fine. –  Aug 10 '20 at 17:23
  • you can wipe cache partition, or install official updates from adb sideload or MicroSD card. nothing more you can do. even chip-off won't work for encrypted device – alecxs Aug 10 '20 at 17:34
  • not sure about this (it's 9006 DLOAD mode) https://forum.xda-developers.com/general/rooting-roms/how-to-backup-qualcomm-phone-root-t3570178 – alecxs Aug 10 '20 at 17:40
  • Sadly that didn't work. Thanks for help anyway. –  Aug 10 '20 at 22:49
