After flashing a stock rom my p5 does not detect SIM card anymore, I looked at the files I flashed and noticed that SEC_ RO is not in the rom I looked at Baseband version under settings in phone but it's showing unknown, imei is showing null tried changing it with mobile uncle still nothing happened, I used MTK droid still did not fix it. I tried the MPOB001 method still nothing works I have downloaded 2 stock rom from different sites all have missing SEC_RO plz help ASAP. thanks
