    Default Factory reset after encrypting

    I performed a factory reset via the boot menu on my phone (which was encrypted). This formatted the /data and /cache partitions. But now it still prompts for a decryption password on startup. But now my old password doesn't work any more.

    Suggestions?

    Factory reset from the boot menu instead?

    That's how I did it the first time. I tried doing it again (and again) but it didn't help.

    Ok, I think I got it! I put the phone in fastboot mode, then ran the following (from the Android SDK):

    fastboot erase userdata

    I then booted into recovery from the fastboot menu, did one more factory erase/reset for good measure, then rebooted the phone normally.

    Funny, I was researching this last night and really couldn't find a good answer. I do wonder, though, if you are supposed to factory reset from Android itself, from settings->Backup & reset, if the device is encrypted?

    But, thanks for the solution...

    I didn't think there would be a difference, but the thought crossed my mind when I ran into this problem.

    Did my solution work for you too?

    I haven't factory reset. But it's good to know what I have to do if I see that problem.

    Hey , I am dying to do exactly what you did to revert the encryption with a fastboot stock flash... i would be using the files from 4.4 ( labeled droid maxx dev) ..
    THe only issue i am having is getting into AP fastboot when the phone is off? The encryption prompt seems to get in the way? How did you get into fastboot on your device? I should be able to handle the fastboot stock restore, i have done it before...

    I used 'none' as the password and it worked for me.

    @drwtsn32 Thanks for this! I have a Motorola Photon Q 4G LTE that I encrypted (Wasn't thinking at the time and didn't look at the cons for doing so) and for some reason I couldn't factory reset it from the settings or from clockwork mod's recovery. Luckily you had the solution so Thank You!
