Hi everyone , i have a problem in my Samsung Galaxy S4 GT I9500 Clone Rooted
Well Yesterday , i had to factory reset my phone due to a virus . it took about 6min .
after the auto reboot , i writed the PIN then it says IMEI Invalid
I tried all the solutions ( but not in the PC because i have a problem drivers won't install MT65xx preloader )
even with mobileuncle tools when i do IMEI backup restore ( MTK ) it says successfull .... then i reboot and nothing happened pls help !!
