[Q] How to recover IMEI when no backup was done

Hi there,
I have a galaxy S I9000. The IMEI i have on my phone when i press *#06# is 004999010640000.
I have NO backup of the EFS folder. Sure.
However, I know the IMEI has it is written on the back on the phone.
How can i restore that?
i have to say that i tried downgrading using ODIN... phone is ok in download mode... I did a lot of research but no luck so far.
Thanks

Hello to recover your IMEI you have to flash a stock 2.3.6 ROM and then backup your EFS folder.
After installing new version, if the problem is persist then restor simply your EFS folder.

Hi Higgins91
Thanks for your answer. With all due respect, I dont think it is a correct solution as I tried it and it did not work.
However, maybe before reinstalling the Stock 2.3.6 i should have tottaly delete the EFS folder (the one with the wrong IMEI). Then the Stock "could" recreate the EFS with the correct IMEI on the phone... (thats only what I did read in another forum - But I have not tested).
Luckily I found my previous EFS backed up. (I thought i never did it, but i did 2 years ago ehheh).
Subject closed, even if there is no real bullet proff solution for that.
Thanks

theres athread in here somewhere about that sorry cant remember where read it about a year ago and if it wasnt here it was on darkyrom Q&A maybe

Lost IMEI

Hello, I lost IMEI data from my i9305 :\
Trying to fix it whole day, but I give up now, im done.
I tried several guides (sammobile.com/forum/showthread.php?t=15196) but nothing helps.
Basicly biggest problem I face is that when I dial to *#7284# it shows "Network is not avilable" so nothing happens, or with another method with removing EFS folder, after backuping it at SDcard1 I have no .nv_data file to modify it and fix everything.
I use SentinelROM v6.0, I tried installing some modified modems, but it was retarded from me. I installed one from orginal firmware today meanwhile I was trying to fix IMEI :\
Can anyone help me?
@edit
I dont have backup. Imei and baseband - unknown ;(
I also would like to add that I know my imei (have it written down :3), but can I somehow rebuild efs based on it :3?

I feel so lucky, I flashed orginal firmware through odin and everything is fine now I just need to upload 4.4 again, and make backup for future!
That was my lesson :3 Thread can be closed.

[Q] No sim detected after flashing custom rom.

I forgot to take backup of efs folder. I found the imei number from the box that the phone came with. I need help to fix the imei issue. Error "No sim detected'. I have Micromax Canvas A250. I have installed colossus Samsung S5 custom rom. I have my IMEI number and I would like to know if there is any option for me to create an EFS folder and add IMEI number to fix this issue. WIFI works just fine. Please help me fix this as I am unable to make any call or use 3G data. I have backedup 'apps+data' option on Titanium backup and copied it in phone and PC. Does it help? Please help me fix it.
Thanks and Regards

Hi folks!
I am a newbie in here. I have a G610Y phone and when I installed new stock rom I lost efs folder. Now my imei's unknown, baseband null and RIL not working after all.
Can you show me a way to solve this. I do not have money for new one.
