I was trying to install a custom ROM on an ACME TB714 tablet and it kind of went wrong. The tablet is set on a boot loop which occurs on the manufacturer logo. The tablet has no volume buttons or a reset button and I don't know how to enter recovery mode and is also rooted.
My goal was to upgrade it from Android KitKat to Lollipop. I tried this using the TWRP apk.
Does anyone know how I can fix this problem and achieve this goal?
