Help with Galaxy S5, SIM card not recognize


Hi Everyone,

I recently purchased a Sprint Galaxy S5 by a company called FreedomPop, when I received the phone everything seems to be working, however after I updated the phone with the 8.1 ROM the SIM card is not detected. Please help me if there is any way how I can make the sim card should work, or if there is no solution please advise how I can reverse my phone to the original room.

Please help because I desperately need this phone to work…

Thanks in advance!


I would try reflashing the rom again, and make sure you clear EVERYTHING on the phone, cache, data,etc. Or trying a nougat rom if that doesnt work. As far as the old rom you would just have to find and download then flash with Odin.
