Chosen Solution

i was playing around in service mode on my I537 and entered the service code *#9090#. My phone shut down, rebooted and now it has no IMEI or baseband and wont read a sim card. I know my phone needs its stock firmware flashed onto it but i don’t have a computer to do it with…Is there anyway to flash old firmware onto a phone without a computer?

Your phone EFS was damage. bring your phone to store and let them fix it for you. or send the phone to me
