I hope the baseband itself is not damaged as well because replacing the baseband chip is a lot harder than it already sounds. Not just the component sourcing and hardware repair procedure, the system main storage has to be reprogrammed as well to pair the baseband IMEI with serial number. It is very difficult and future upgrade may fail.

Usually it's just a power issue, the baseband power supply part is damaged. Find the broken part, replace a capacitor or inductor, or baseband PMU at most.

thanks for your reply, i don't know whats wrong but i wrote a bigger message here early in the morning totally but it disappeared i cant understand why, i am new person here and i am new to hardware repairs most especially apple but i gather info from internet since i come from where there is no apple care center...

i have not even touched the iphone5 since morning because an expert engineer promised to help out with it but its sad for me he failed and now i am on my own on this phone and i dont want to do anything stupid, i dont know the terms you used and i so confused right now because the phone in question still show the bluetooth addres and wifi address correctly but the IMEI doesnt show and the modem firmware is BLANk...

pls help with maybe picture or schematic or something that can put me on the right vivid lane on this iphone issue because thinking about how it all happened gives me headache. your further help would be appreciated... if you skype my id is oluromeo... please reply.

i have the same problem. it happened 3 days ago. i've done everything. reset, upgrade, sim in sim out, all the thing that i can possibly do by my self...

finally i went to apple service centre. they said it is about a hardware issue. they should change one part of the chip in the firmware. it costs 120 USD to fix it. and my iphone has to stay there for 2 days...

so in my experience theres nothing to do except ask someone to replace the chip.

i have iphone 5 with ios 8.3.

Thanks.
