Hello,
I`m new to rooting and installing custom ROMs and in the process I lost my IMEI number ( it just shows a generic one now) .
My Galaxy S2 was initally from Orange Romania. It was unlocked for UK and it worked for a loong while. It had gingerbread version. I rooted it and added JB neatrom with a syiah kernel. All seemed alright except I had no service anymore. I tried going back to quite a few stock firmwares for UK T Mobile ( I use Tmobile pay as you go). Some of them sent my phone into bootlooping. The current version I have is this one: http://www.sammobile.com/firmwares/download/29852/I9100XXMS7_I9100OXAMS7_XEO/ and it is sucessfully rooted. Ironass here on the forums helped me a lot with this.
Before adding the JB NeatROM, I used GSII repair and made a backup of the efs. I have a file on my computer:
efs_save.tar from 22 september.
On the phone, just in My files I have these 2: efsdev-mmcblk0p1.img.gz & efsbackup.tar.gz from 23 sept
All these should be related to the good backup.
A few days later, when I had a different ROM and the network problem I did another efs backup , also using GSII repair so in my phone , in the GSII_repair folder there are : efs_save.tar & efs_save.tar.gz from 25 sept but these files are bad I suppose.
I took a look at post #2 here: http://forum.xda-developers.com/galaxy-s2/help/efs-restore-backup-t1377105 but it seems complicated as I never used ADB before.
However, if someone could please guide me through step by step what should I do, it will be very appreciated!!!
I have installed ADB following this guide http://www.howtogeek.com/125769/how-to-install-and-use-abd-the-android-debug-bridge-utility/ and I can see my device when I connect it.
I have 7zip on my PC if I need to explore the .tar
I installed ES file explorer. I found the efs folder. There, I have nv_data.bin and nv_data.bin.md5 files and their date is shown as 2 oct 015. I don`t have in the efs folder the .nv_data.bak & nv_data.bak.md5 in that folder.
What should I do ?
