Hello there, i tried flashing the rom and the first time i got an error mounting the system then i tried flashing several more time but no luck have a look in the photos.
I tried clean flashing the rom. ( wipe dalvik\cache\system and data) then flashing the zip file.
Bro the procedure should be :-
1) create a backup u already know how to do it
2) using twrp wipe cache ,dalvik cache , system ,data& factory reset
3) unmounnt data daalvic cache & system aand data
4) now try to flash the zip file and if u r unable to boot to reecovery menu try mobile uncle tool to go to recovery nd if not posssible then try reflashing stock rom using ygdp if u r stuck on bootlop or phone not going into recovery..thats the only choice
Press thanks if i help it motivates me
