Please help me Restoring IMEI

Hey guys,
I installed S3-Evolution-Beta-3.1 in my SGA a week before and just 2 days back, I found the strange problem that even if my phone had a SIM card in it, My phone was saying "No Network". First I thought, I was in the No Reception area, and ignored it. I restarted my phone, did the couple of tricks of restoring the Nandroid Back up etc. ***Nothing Worked*** to resolve the "No Service" problem.
I just flashed the DDKQ8 firmware through Odin, and the problem still continues.
Just a couple of hours back I observed that there is NO IMEI number in the settings. I tried going into the service mode and tried turn off the FTM and choose proper network bands. But nothing worked.
Now I am getting worried, Please help me out.
PS: I knew this kind of problem, and have the original IMEI number with me.

Please help!

So there isn't any possible solution?

Dial *#06#
If you can't get you IMEI number, I'm sorry but you've bricked your device, go to support service if you' ve your warranty available

[Q] My IMEI was deleted. Factory data reset doesn't help.

Hi All,
Something really strange just happen with my GT-I9295.
So I got the 4.2.2 version from the box. I recived an automatic upgrade which I have accepted and installed. But strangly after installation the version still 4.2.2. One week later the IMEI number just disapeard durring the night and cannot recover it anymore.
Network
Unknown
IMEI
Unknown
I didn't installed any custom ROMs, nothing.
I found that the IMEI number should be in EFS folder after factory data reset, but this file is missing there.
I have my IMEI under the back-cover, but how I can re-enter it in my phone ?
I heard the param.bin for gti9295 could help ? Could somone drop it here ?
I bought the phone 2 weeks ago
When I tried to repair it I have root it. How I can check my KNOX counter to see if I can send it back to Samsung ?
Thanks in advance and sorry for my english!

Unknown IMEI and locked network after trying to recover

Hi everyone,
Hope you can help me solve this, cuz I'm way out of my knowledge..
My phone broke the lcd and was out of action for a few months.. After I finally got a replacement screen, the phone wasn't working and said IMEI unknown, I've tried to flash a few roms via recovery but nothing. So I just went crazy and flashed it via kies. It worked, the imei appeared but the phone was locked again..
Back to the shelf a few weeks until I could afford to pay for unlock.. When I picked it up, it was unknown IMEI again and the guy at the shop basically told me he couldn't help.
Was he right? I refuse to believe I can't recover the phone.. Can you please help?
Thanks!

Anyone?

Are you sure is that phone imei is not blocked, because provider may block if it is stolen reported.
I had the same problem after changing display IMEI unknown
But somehow it was saved from 'unknown IMEI' I don't know how.
restored efs from previous backup (twrp & philz recovery)
- no imei
I flashed stock
- no IMEI
asop
- no imei
tried different modems
again stock
- suddenly its worked
(some users reported flashing different modems worked for them)

Yes I'm sure imei is not blocked by network. Have a friend that bought a phone which he discovered the hard way it was stolen, anyway, blocked imei by network behavior is completely different.
This is what happened to me first time only valid imei after kies rom update.

If you see imei again, Make a backup using pc, there is a guide in development section. So, you can easily restore again.

GT-I9305 - Baseband version unknown, IMEI unknown, IMEISV unknown, *#06# null/null

GT-I9305 - Croatian market, T-Mobile
hi,
got the phone for repair. under baseband version is unknown, IMEI is unknown, IMEISV is unknown, *#06# comes up with null/null.
i read all the guides i could find and tried everything. found the apps that could help me but cant seem to get the phone recognized with them (QPST, NV-items reader writer, Qualcomm NV Tools that comes with EFS pro)
drivers are ok, ports are recognized, everything is as it should be but in QPST under phone it says "no phone", NV-items reader writer says "Failed.. Phone does not answer" and Qualcomm NV Tools "Unable to send SPC to the phone!"
tried with RNDIS+DM+MODEM and DM+MODEM+ADB and EFS professionals auto switch while launching Qualcomm NV Tools from EFS professional.
does it matter which options are selected on the first page of "service mode"?
UART
modem
pda - selected
USB
modem
pda - selected
although i tried with modem selected also
phone was stock but couldnt get it to be recognized, then rooted (supersu, busy box)and the problem is the same.
i managed to get it connected to EFS professional, but with it i can only backup and restore already corrupted EFS.. cant modify the backup to enter/fix the IMEI.. and simply backup/restore as some have suggested doesnt fix the problem
flashing param doesnt help, flashing different stock doesnt help.. havent tried "Perseus Kernel" which seems to help some, as im sure it would "fix" the problem.. but i need the phone to be stock and in working condition.. also the friend who gave me the phone sad that this just "happened", he didnt do anything.. the IMEI just disappeared
tnx to everyone in advance

no one :/

have you followed instruction here step by step? http://forum.xda-developers.com/gal...warning-guide-backup-restore-imei-nv-t1946915
this guide does not use EFS Pro. I can't really help. I never managed to brick my phone like that. If the phone won't be recognized it could be that the USB port is broken. Had happened to many S3's, I had to get mine fixed twice. Or are you able to get a connection to your PC?
