My tecno boom j8 shows blank screen when I switch it on. I flashed it back to stock rom with sp Flash tool then it started that. The phone is working but shows a blank screen.
I need help as soon as possible. Thanks

Or if I can get a boom j8 rom backup from someone to download. .

did you make any back up before flashing?
if no... try factory reset

Download on and flash with so flashtool

You flashed the wrong variety of rom find the exact rom built number like the one you had before you flashed this one.

I downloaded this firmware "Tecno Boom J8 (J8-H354-C1-L-HiOS-20160310)" but it shows blank screen after flashing with sp flash tool..

Tecno Boom J8 (J8-H354-C1-L-HiOS-20160310) is the only version I can find online.i can't find another one.

This was the last screenshot I took before flashing it.

That's dangerous flashing without a backup...
Do a hard reset...lemme know if it still persist

Take it to Carlcare
