I need help please !!!! - Galaxy S III Q&A, Help & Troubleshooting

Hi guys
I bought samsung galaxy s3 i9300 sprint and it was working with me pretty good until i installed a new customed rom , and rom was working fine and one day i have lost my mind and wanted to increase the ram so i downloaded an app after i rooted my phone and instead i format the sd card parition i have formatted the efs and my phone doesnt boot , was freezing on the startup so i Google and found out to download efs repair and after it worked fine but i cant make any calls it gives me a fake IMEI , i installed new official rom 4.1 and 4.3 and changed too many modems all kinds of modems i think but nothing worked and my IMEI still not restored to the orginial one that is written on the back of my phone .
i noticed later that whatever i install from modems it is like nothing because efs folder in my phone missing the the file that my IMEI stored in so i got later that the file that store my original IMEI is missing from ESF folder
I also tried everystep about busybox and emulator dos and nothing worked with me because i think i need to rewrite again my IMEI .
Is there any means to do that or anyone upload me EFS folder of same phone or i will just throw my phone now i dont know what to do i havent enjoy my phone more than one month

Wrong phone, wrong forum. This is for the i9300 only.
If you've wiped your efs then nothing you can do, take it to a repair centre and pay them to fix it.
Questions go in the q&a section, not general.

I cannot help here, but i suggest having a more specific title for the topic.
thanks!

Theres no way to fix it unless u have a back up of ur efs. And yeah. this forum is for the international version not the sprint version. Go to the repair center and ask them to fix it for u. You most probably formatted ur internal memory since its called the sdcard. ur ext sd card is called the sdcard1

Local shop will fix this a lot cheaper than Sammy service center. Efs is not located on int SD so wiping int SD won't wipe you're efs. Any back ups you made to int SD would be wiped.

He formatted the internal memory, not factory reset.

Yes and formatting won't delete the efs folder. Its not located in int SD. Trust me bk up your int and wipe it. Efs is not affected by formatting int

Efs I learned a lot about on the s2. S2 and s3 and all Sammy phone work the efs the same. What's nv_data.bin file size. The PIC is to show that efs folder isn't in int SD. Any efs file that's in int SD is a copy and same as with ext SD.
Also try this out...
http://forum.xda-developers.com/galaxy-s2/help/solved-stuck-flight-mode-efs-issue-t1261948 may help may not but its worth a go on the s3. There also is a man on xda who can fix efs...all he needs is control of you're PC to make it happen but he charges for this. Interested? Not been interested in efs folder since s2 but now I'm getting interested again.

Thank you too much i appreciate your help really , i wanna really say when i take my phone to
repair shop all they say they dont have zx3 box and the tools to maintain it otherwise i would
have fixed it but really here maintaining centers too bad they all just told me replace the
motherboard and buy new one i think this is stupid just i buy a phone and after a month i
throw it because of efs corrupt (sorry for the headache). i checked the link you showd me and
when i access the efs with the root folder i found all files that they guy mentioned in efs
folder except this file name (.nv_data.bak) i couldnt find it inside my efs folder .do you
think the problem is there because i have not this file
another request please u said there is a man on xda an fix it , would please tell me how to
contact him and how be in touch with so he can fix it, i dnt mind he control my pc the most
important i wanna my phone works again and i agree about the charges .. there is something else before i have this problem with efs folder i made a copy with clockworldmod for whole system on my memory card but when i restore the version the IMEi is the same doesnt change , i have an idea i dont know it is rght or wrong i wanted to extract that clockwordmod backup and fine efs folder and use it , i dontknow that clockwordmod where it keeps efs folder or even it does back up to efs when i used clockwordmod
Thank you too much for
your support

This is odia. Pm him you're problem and details and wait! Do not bug him! This man has crazy skills with android. And Sammy said replace mb! Thats just lazy of them to say that. for probably a quicker fix go to a different local shop.
