First I want to apologize if I have some errors, my english is not very good, so sorry about that, I will try to do my best to explain and give the best background information if anyone can help me.
My actual phone is an Motorola Atrix 2, and I have flashed roms several times following the procedures explained on the threads here in this awesome site XDA step by step. So being able to flash roms with no problem at all I tried to do the same on my wifes old Samsung I9070.
I followed a thread that explained how to flash a ROM from GB to Kit Kat for the I9070 step by step here on XDA. The thread is this one:
It all went fine but being that the phone was not being used by anybody I forgot to insert a SIM CARD before the flashing procedure. I really don't know if that makes a difference, but when the mobile booted the first time after the ROM flashing I inserted my SIM card and to my surprise I didnt recognized it... booted the phone again several times and nothing, but the SIM card is being detected right away on my Motorola.
So I tried to do some research about that and some people suggested to go back to stock firmware, and others told that it was a problem with the EFS folder.
So I tried going back to stock JB with ODIN, but this time with the SIM CARD inserted, and nothing, the same problem. So I tried inspecting the EFS folder and I think that is the problem but I need some advice on this.
The EFS FOLDER has this content:
A bunch of files named CRYPTPROP...
And some folders inside... Thats all. I didnt made any backups of the phone or the EFS folder
So I tried using the code *#06# and it gives a valid IMEI 3544******* etc
I really don't know how the phone still shows a valid IMEI with the file NV_DATA.BIN missing, so I checked the phone information and found this:
MODEL NUMBER: GT-I9070
ANDROID VERSION: 4.1.2
BASEBAND VERSION: I9070XXLQL
KERNEL VERSION: 3.0.31 - 1485715
BUILD NUMBER: JZO54K.I9070XXLQL
Inside SETTINGS - STATUS:
SERVICE STATE: OUT OF SERVICE
MOBILE NETWORK STATE: DISCONNECTED
MY PHONE NUMBER: UNKNOWN
Maybe the EFS folder is not all bad, I really dont know, please I need some advice here. My motorola screen is dying and I need to recover this one as it is a good phone. Thanks in advance for your help.
