Hi Everyone,
I have purchased my Xperiz Z 'C6602' in the start of this year (2014). Yesterday, I faced a problem that my mobile was showing no Sim card detection. I have restarted my mobile many times, open the Sim slot and again placed it corrected but the problem persists. I have reset my mobile, check the aeroplane mode but all is well. I am wondering that how this happened because my mobile was working great. I used it at night very well and then after some hours at morning the mobile showed no network connection (detect no Sim) while the Sim was in the Sim Slot.
Please tell me the solution of this problem. Thanks

Unknown IMEI Number after Stock Firmware Flash

Hello,
ive got a S6 edge (SM-G925F) from someone with lineageos 14 installed. The Sim Card hadnt been recognized from the start, so i thought i flash the stock Firmware to reset it.
Even after flashing various stock Firmwares, the Sim card doesnt get recognized. There is also no IMEI and IMEISV Number. Its just unknown.
I tried flashing

- Vodafone Firmware
all with the same Result.
Does someone know a fix?
