Samsung Galaxy S4 Baseband version and imei unknown

[pinklike]

hi, this is my first post ever.
i have a galaxy S4 GT-19500. few days back a software update appeared, i didnt asked for it, it automatically appeared and after i installed it. the network signal diasappered.
since then
when I insert sim card it still says Insert sim card
android version has changed to 4.3 (it was 4.2.2 before)
IMEI is null/null or says unknown (but sometimes once a day it shows the imei for few minutes)
baseband version is Unknown
IMEI SV is unknown
bluetooth address is unavailable
battery has started draining early.

I have tried factory reset several times, inserted different sims,

I live in Pakistan and my brother bought a Samsung Galaxy S4 from UAE for me, so If it needs a warantty claim then I will have to send it back to dubai which is hard for me to do.
PLEASE HELP

try doing a reinstall of software via odin if possible...it sounds like a corrupt EFS folder which contains your imei number if this gets corrupted then phone is bricked which mean send back for waaranty

thankyou but it is not possible for me to send it back to UAE and i can not claim this warentty in Pakistan, i went to a software shop he said you will have to change the baseband which is a hardware problem and it will cost you a lot. do u suggest me to go for this.

Go to service in your country, it's possible that this is your only option. That happened to me with my former S3 for flashing the wrong firmware and destroyed my imei number. In service they have a special USB cable and proper software to restore your imei number as printed in the back of the interior of your phone.
Good luck,
