IMEI question

---

Is there a chance of getting IMEI corruption when upgrading from AOKP/ICS to AOKP/JB ?
I had this problem when upgraded my Captivate from ICS/SLIM to JB/SLIM

I thought the only time your IMEI was in any danger was during an unofficial unlock process. A ROM shouldn't mess with that data. I haven't seen any reports of ANY ROMs hurting the IMEI. I went back and forth from GB to ICS to JB a few times without issue.

The IMEI should be stored in /efs (I think) so as long as you have a backup of that you should be fine.

I may be wrong but my guess is they had to change the filesystem from rfs to mtd for jellybean on the cappy. It allows bigger partitions, but efs gets misplaced during conversion. I don't think this was ever an issue on s2.

I derped my IMEI on my S3 so I have done a lot of reading about it. This is what I have gathered, the S2 keeps it in a nice neet little folder called the EFS as d3athsdoor has mention. There are several ways to back it up but for the S2 I have read that this https://play.google.com/store/apps/d...51bGwsMSwyLDNd works nicely and can be restored with the same app. On the S3 the IMEI and other important data hasn't been confirmed where it is stored yet because it is in different locations, But there are some really smart people looking for it. But in your case just back it up before you go to flashing (if you choose so). I have backed my S2 up with the Ktool app.

Def back it up, because if you mess it up you cant restore it without back up

They already found the IMEI bro. You have to use a Qualcomm tool to back up and restore it. Check the dev section (ATT version is what I have)
