    it wouldnt boot into recovery for me

  2. Terry says:

    Getting ‘No command’ when I try to boot into recovery. Any ideas?

  3. Aidan Hall says:

    If you get the NO COMMAND error, remember that the flashing on some devices only lasts untill it powers off.
    Right after i flashed the recovery and rebooted i help volume up as it turned on and popped right in to the right recovery.
    successfully rooted now.

  5. Wilmer says:

    Hi my phone was working perfectly and It was working with the root access but then suddenly it stopped working . I tried to reinstall the zip filled from recovery mode but apparently the root access has gone and the SU app is prompting an update message and when I click ok then it appears an error message. I tried to fix it by installing a update fixer but it says that there is no SU app detected.

  6. sortingbeans says:

    I rooted it, I can access custom recovery, but SuperSU is not appearing in my app drawer. It’s listed in my downloaded apps, but I cannot access it through my app drawer. Any suggestions? Thanks!
