i recently bought a BOOST Mobile Shaker-Slim Android 5.1.1 phone and decided to root the unit, it was my first time doing so and i came across Kingo Root and used the APK, the phone made a weird noise and went off.
I pulled the battery and the unit was fine, i tried again afterwards with the Kingo Desktop App and it worked fine. The phone status was rooted and i unplugged the usb cable after the unit stated that it was done and then the phone went off. After another battery pull it only showed the OEM logo but no sound or interface. I read up on the whole rooting thing and never once thought of doing a backup of the ROM neither did i know that was even possible as i should have. I got a .pac ROM for a BOOST Mobile Shaker-Slim online but it was for an older android version, v4.4.2, which seemed fine, after hours of struggling i managed to flash the phone with that ROM, now there is sound and i can change the volume etc but the screen stays white, is it maybe a resolution issue? what can i do to fix this?
