Help No IMEI, i747

[Grendelin]

So, after finally solving some other issues on my phone thanks to dmcjr22 on this forum, I've run into some new problems.

I no longer have an IEMI number. Google had some great suggestions and I've tried just about all of them, but no luck.

[TUTORIAL] IMEI - Backup NV with QPST - US Variants - Galaxy S III (All Variants) - RootzWiki

Was the best candidate, but the nvbackup files does not actually exist on my phone anymore.

Are there any other suggestions or possible some kind of flashable I can use to get my phone back into working order?

Solved the issue.

[Q] Baseband Version & IMEI Unknown - Pg. 2 | AT&T Galaxy S3 | XDA Forum

flashing this modem "ATT_GalaxyS3_UCUFNE4_Modem" is what did the trick. directions in the post above.

great job!! Im glad you got it fixed, i felt bad because i helped ya get to that point. I should of told ya about how custom roms can potentially erase your imei. I always forget because the s3 was the only phone i learned ya had to worry about it. Now that you have it restored xda has forums in how to save a backup of your efs folder which contains it. You should also make a nandroid(backup)of your phone via recovery as well.

Had this issue with a Note 2, stock & not rooted.

So that was fun, had to send it to Samsung, spent a lot of time trying allsorts before admitting defeat.

Making an efs folder backup is the first thing I did! Also did a full system backup, so hopefully I'll be set for the future.

Thanks again for all the help.
