No IMEI, BASEBAND, (GUIDE)

So... Tonught I was happily having a game on draw something with the mrs.. Then noticed a no entry looking sign where my signal was.. Took the sim out wiped it put it back in.. Same again.. Thort strange.. Must of crashed or something..

Anyways..

Did a factory reset. ( settings - privacy - factory reset)

This didnt work either nor did hard reset using the code..

Anyways.. Looked all over the internet and most forums said basically.. Warranty.. Send it back..
As i baught it second hand wasnt sure of wether i could so kept looking....

I then found this.. And my god it was a godsend. I was convinced my phone was dead..

Solution 100% solved and WOrking ( BY ME )

1st step , download any compatible android firmware available in your hands. ( if your phone isin't stuck in a boot loop , skip this step, or if u can use everything but GSM cellular network, or any other connection provided by your sim card provider )
2nd : root your mobile using this toolkit here's the link

3rd: step : search in the market for GSII_repair app ( needs root aka superuser access )
4rth step : repair your efs files using this app . ( it's obvious when u look at it )
5th step : search in the market for galaxy s unlock ( follow steps , easy ones )
6th step : ENJOY having your phone back from the dead

As someone said make sure your busybox is installed correctly.

My phone was as stange as hell.. I set up a lock screen before it all happened.. For some reason after a factory reset.. my lock screen showed up. But for some reason o could draw any dots and it would unlock it..

Also i had no imei.. No baseband. No bluetooth.. Wifi would work. But anything tondo with my gsm sim care would not work..

When using GS11_repair.. Skip the first tab and goto the repair tab. Do everything in order on that page.. The unlock part i didnt do as my phones the unlockes debranded firmware so didnt need it. I only did the first 2 steps and magically everything just came right..

Hope this mini guide helps.

Apparently the problem is your nv_data file is corrupt. Which is in or around your efs folder which has all the information about your phone [imei baseband etc]

backing up and restoring your efs and deleting the old nv_data file fixes the problem for apparently 9/10 gs2's.

MAKE SURE YOU BACK UP YOUR EFS.. 2 FILES SHOULD BE BACKED UP IN THIS PROCEDURE. IF I WAS YOU.. UPLOAD THESE 2 VERY IMPORTANT FILES TO YOUR DROP BOX OR WHATEVER SO YOU ALWAYS HAVE THEM SHOULD YOU NEED THEM.

Apparently theres other tools that do the same job. The info i posted was the only info i couls find when it happened to me so shared the info with anyone having the same issues.

I dont know what this software does. I didnt do all steps stated on GSII_Repair.. I backed up my efs then mounted it.. Didnt trust deleting anything and everthing was fine for me after a reboot. This was performed on GB stock 2.3.4rom

Actually did me a favour as was forced to root. Now running ICS so happy days lol
