[Appiah Smart]

My samsung galaxy s5 model G900P always shows
INVALID SIM CARD after i mistakenly wipe
EFS/NVM with z3x samsung tool pro software.
I upgraded my phone from 5.0 to 6.0.1.
after doing this,it started giving me problems
anytime i switch on the phone.
such problems are: 1)the battery drains faster.
2) the phone always shows checking device
status continuosly anytime it is switched on.
3)no sim supports LTE/CDMA network mode.
4)NO 4G network data only 3G network data
and making browsing too slow.
5)reactivating and a whole lot without end
anytime i switch on the phone.
The above listed number 1 to 5 are the issues
that i was facing so i connected the phone
to laptop with usb cable to solve it but
i couldn't.
Z3X SAMSUNG TOOL PRO was the app.( repair mode)
that i was trying to use to solve and
mistakenly, i go to wipe EFS/NVM but after
processing the phone did not reboot.
So i disconnected from the usb and remove
the battery and inserted it again.
I switch on the phone and now the phone has
also started INVALID SIM CARD.
PLEASE PLEASE PLEASE read this and help me
with solution to the listed above 1 to 5 and the invalid sim card.
please help me save my phone.
ALL BOSS.

You have to repair the problem with the EFS - put the proper IMEI, etc., back into the phone. The bad EFS data is what's causing all the other problems. If you can't do it, you'll have to find a repair shop that can (most won't [and won't work on any phone you messed up yourself, hardware or software] or can't). And Sprint isn't going to be much help. Most "Sprint" stores are actually independently-owned sales outlets and couldn't repair a phone if their lives depended on it.
