[Please help] Tecno tunes J7 - Blank Screen after Full Firmware Flash

#1

Dear Hovatek Members,

I have a Tecno tunesJ7 that i flashed but it now displays blank screen. On forums i see 3 J7 variants:

1. TECNO J7 TECNO J7-G345-A1-KK-20150309
2. TECNO J7 II TECNO J7 TG345-A1-KK-EG-20150425
3. TECNO J7 III J7-G345-A1-KK-RWA-MTN-R6-20150706


I have used the TECNO J7 TECNO J7-G345-A1-KK-20150309 firmware. I am not sure if the last two will work as well.

Need your help on the specific file of the phone.

Your assistance is highly appreciated.

Try flashing only lk.bin from the other variants.

Dear Hovatek,

Thank you for your quick and timely assistance.

The firmware flash was successfull with TECNO J7 III J7-G345-A1-KK-RWA-MTN-R6-20150706 but the problem i encounter now is whenever i insert my simcard it displays a message insert MTN Simcard to activate your simcard unfortunately There is no MTN in my country.

Is there a way of flashing that i can bypass the network lock so that i can use any simcard?.

Your assistance is highly appreciated.

you were supposed to flash only lk.bin, not the entire ROM.
Reflash the previous firmware then flash only lk.bin (Uboot)
