    Model: Samsung Galaxy S3 AT&T i747


    I was forced to encrypt my galaxy s3 in order to receive corporate emails on my phone using the stock email app. However I never imagined that encrypting the phone would literally lock the memory and options to customize the phone.
    I tried to root the phone to benefit from more flexibility and also debloat the phone. However during the rooting process, I could not mount /emmc/ when using ClockWorkRecovery in the startup menu. Based on what I found on the web, I figured it was due to the encryption.

    I then tried to factory reset the phone to get rid of the encryption but I simply can't hard reset the phone from the OS or the startup menu. When doing the reset from the startup menu, the errors are "Can't mount /sdcard/". The reset continues but when the phone reboots, all my applications and personal data are there and the phone is still encrypted.

    I read a lot about flashing a custom recovery via flashboot or ADB but I am reluctant to do it without guidance from the experts (you guys).

    I deleted my corporate email account (It is my personal phone, I am not required to install exchange on it).

    I tried to use an external sd card but as soon as the phone recoginizes it, I have to encrypt the card as well as a result from the corporate policies. I ejected the card and did not encrypt it.

    I am new to android (long time iPhone user) and I would really appreciate your guidance on the methods to factory reset my phone or a different technique to get rid of the encryption because I am really stuck right now.
