  • Hello, I have tried these steps on Alcatel Raven A574BL with Android 7.1.1 but it does not work. Would you have a guide for the specified model?

    • i read on xda that it can't be done on a Alcatel Raven A574BL. I was having the same issues with that exact phone.

    • either by typing:
      adb reboot bootloader
      or by turning off your phone, and holding the volume down button when turning it on

  • I believe that because of security issues the Alcatel Raven A574Bl doe's not have the option "Fastboot Mode" but does have the Android reboot menu which is really odd because in the Developer Options theres the OEM unlocking toggle switch thus leaving me to further believe that what you seek can only be done by paying for it

  • Does this process work with the Alcatel 3V 5032w? I really want to unlock the bootloader on this phone or I'm getting rid of it.

  • like i already own the phone but i have to pay to unlock its crap feel like busting it with a sledge hammer
