This is a known issue when trying to flash MIUI, the EFS folder hasn't been backed up correctly.

A lot of people have had mis-reported IMEI numbers and by reverting back to Froyo using my MIUI Easy Install guide have reported success.

May be worth a try following the guide to the point of restoring Froyo using the files I've included, then feel free to flash what ever firmware you wish afterwards!

Hope this helps!

And I'm really glad I came across reading these issues before it happened to me (not yet so far), so if you read this and your IMEI is still fine, back up your /efs folder just in case:

Help!

Hey guys I just updated to the latest version of MIUI (mcgv6 from v5)

Initially, I couldnt access my external sd card because i had installed a stock JPY rom (wrong bootloaders).

So I tried to flash a safe base froyo rom (with speedmod kernal and correct bootloaders) onto my sgs using odin. I did this straight from having miui 1.6.3, and it didnt work... after the phone rebooted it took me to the recovery menu, where it said i needed to format the internal sd or something.

Then it came up with an orange exclamation mark in a white triangle next to an android robot.

I restarted my phone and tried to flash again but it odin froze, so I yanked the battery out after waiting... this resulted in Kernel failure (phone to pc symbol).

I could not access recovery mode but I could access download mode, so flashed stock jpy rom and it worked! :D then used the modified rom and then installed efs backup then the cm7 initial kernal. After formatting the system/data/cache as well as dalvik cache I installed MCGv6.zip.

It worked :D.... I can finally access my external sd.

HOWEVER, I couldnt get my network to work: SOS only

And when I go into advanced call settings, it says: Network or sim card error.

I checked my IMEI and it comes up with: 004999010640000

I know this had definitely changed, and as a newbie to this kind of stuff, has anybody got a comprehensive guide of what to do??!

I love this rom and my samsung galaxy s, and I just want it working again!!

Many thanks!

I installed efs backup.zip for my galaxy s

Not as far as I am aware. I got a firmware update notification from the official KIES software. Kies software still says it needs an update. This is What it says.... <GT-I9000>'s Firmware can be upgraded, please click here to upgrade....

Current Version :PDA:JF3 /Phone :JF3

Latest Version: PDA:JFA /Phone:JFA

When you upgrade it just goes through the motions and then after completion you reconnect and it says the same thing again.

The phone functions normally but i just cant get or make calls because the IMEI is rejected by orange because its that default 0049 one that everyone else with this problem has.

[Galaxy S I9000 Q&A, Help & Troubleshooting] supercurio:
My recommendations :

- NEVER check Debug / Phone EFS Clear in Odin

- If you're rooted, make a backup of your /efs directory

- If you play with Odin and firmwares, consider rooting to backup your /efs

For research purposes, i wrote the content of the /efs of another Galaxy S into mine.

After a reboot, I got the 004999010640000 IMEI too.

Hopefully, after restoring a previous /efs backup, everything came back right.

Explanation :

/efs/nv_data.bin contains IMEI data in encrypted form (and some more device-specific infos).

If the phone software/baseband can't match nv_data.bin with real hardware values, you get the mock IMEI 004999010640000.

This is the same thing if you wipe EFS. You loose your nv_data.bin and same **** happend.

I suppose that a software exist to re-build the appropriate nv_data.bin.

This software must contain baseband vendor code, and is probably highly confidential.
[Galaxy S I9000 Q&A, Help & Troubleshooting] Daemos:

[Galaxy S I9000 Q&A, Help & Troubleshooting] stierney:
Thx for the info. The curious thing is i only used Kies for an update, or attempted update. so are you saying that you need to root your device to back up this file? I cant see an icon from within KIES to back up the phone so im assuming that it isnt possible to do using standard Samsung authorised software..?

When i get my phone back its the first thing im gonna do if it is possible to backup this in some way using an app or authorised software

Im not sure i wanna go making changes until i know i can recover from them without invalidating my warranty!

[Galaxy S I9000 Q&A, Help & Troubleshooting] nufclad:
So basically, if i had 2 Galaxy S's, one blocked.. i could transfer the one that isnt blocked and transfer the data files, and put them on the blocked to make that unblocked(with an unblocked imei) so this is a very simple basis of IMEI changing on a new mobile device. :confused:

now, all you need is someone who can read the datafiles, decrypt them.. and then you can select your own IMEI number?
[Galaxy S I9000 Q&A, Help & Troubleshooting] rkantos:
Decrypting those files would probably be impossible. IMEI changing is illegal in most countries, that's why it has been made difficult.
[Galaxy S I9000 Q&A, Help & Troubleshooting] supercurio:
Basic, unix permissions lost :

su
busybox cp -a /efs /sdcard/

Clean :

su
busybox tar zcvf /sdcard/efs-backup.tar.gz /efs

RAW :

su
cat /dev/block/stl3 > /sdcard/efs_dev-block-stl3.img

Restoring prior /efs backup would be the answer for the OP, but I guess it's too late now.

Working IMEI requires both matching IMEI crammed into hardware + nv_data.bin loaded by the modem firmware.

If you put the nv_data.bin from phone B into phone A, phone A will defaults back to the special IMEI 004999010640000.

I don't know if phone A will be unlocked like phone B (I doubt it, but why not!)

Note that i could call & receive calls with IMEI 004999010640000, use EDGE & HSDPA too with the carrier Orange / France.

Decrypting nv_data.bin or building one from scratch is the tricky part :D

Yep !

Just copying set the IMEI to 004999010640000, both my test phones were unlocked so I can't tell more ;)

[Galaxy S I9000 Q&A, Help & Troubleshooting] midas5:
Imei is not that important. Think of it as like a MAC address in Ethernet network. It should be unique for the protocol to work. If you change your Imei, you might change it to be the same as someone else's that will cause the registration process to get confused. Most likely, neither phone will work reliably after that. It has nothing to do with how the billing for the cost of calls works. There is no legal problem for people discussing how to recover their own Imei if it has been corrupted. Don't post your Imei publicly because someone else might use it resulting in problems for you.

EFS backup the easy way

A great way to save all this heart ache trying to correct problems that i have read within this forum is to install SGS unlock pro app from the market money well spent. It allows you to unlock your phone & also to backup & restore your EFS folder. I had the same problem when installing a ICS rom over a GB rom & finished up with the same problem of a false IMEI as shown on many posts. I restored the backed up EFS folder job done problem sorted so easy hope this will help many other people & save further problems related to your EFS folder.

Just registered to say that I got a working IMEI back by reverting back to the "stock" rom of I9000 provided in "flashing tutorial for dummies" (upto step 4, without flashing ICS right afterwards).

I reverted from CyanogenMod 10 to 2.3.x and the IMEI just reappeared out of nowhere (didn't backup the original efs folder before starting all this modding business, silly me). After that I backed up the efs folder (to my PC), flashed CM10 in again, pasted efs back and the thing just started working as it should. Before CM10 (with no IMEI) I tried 3-4 different roms with no results. I bought this I9000 from a friend and it had CyanogenMod 7 in it when I got it.

For efs backup I used AndroidMate's file system tool.

Two days of battling on this issue and now I can make some phone calls too. :D
