HELP!!! lost mi IMEI and I don't have a EFS Backup

Hello, I was trying to unlock my galaxy tab P7500, and for some reason I lost the efs backup, or it got overwritten or something, base line, I don't have the backup, now the IMEI is 004999010640000 and the serial number is 00000000000, obviously, it does not connect to the network, I've tried every post I found that states I can restore my IMEI, flashed older firmware, flashed the original one and many other things, but none seems to work, so now I really don't know what else to do, I know my IMEI number and my serial because is still in the sticker on the back of the tab, and is in the sticker on the box, and is on the purchase receipt.
So any ideas what should I do?
GT-P7500 from movistar venezuela, now on Official ICS LQ8 ITV

Do u still have the imei number that on the back of ur tab? If u do I advise to you is going over to t-mobile gs 3 dev section. They have a tool call nv and imei injection and give it a shot.

thanks!, is that a web site? or a office? I'm currently in Bogotá, Colombia, so if your advice needs me to take the tab to a t-mob office I think is not going to be possible.

You can purchase used motherboards on eBay but they may be hard to come by. Generally a used MB either has a bad ESN if it is carrier branded or it has something else wrong possibly water damage. What is wrong with your signal? Why are you trying to get a new MB

IMEI would not be blocked the phone sells fully unlocked. Try to
1. Do a hard reset
2. Flash new stock firmware via Odin
3. Try a different SIM from another carrier.
4. Try to restore the IMEI EFS NV-data.bin file.

I believe Philz CWM has an option in recovery to restore your EFS check here
Hopefully a backup exists on your phone if not your going to have to restore without a backup. Search the forums here on how to restore without a backup if that does not work

poped my EE sim in phone found a good signal spot ,strange i can get data downloads but no voice or sms ,puzzled now

Your better off calling a carrier (3, t mob etc) ask them to check the imei. I brought 1 off ebay, worked great for 2 weeks then lost signal, tried loads of sims, some showed signal but wouldnt let me make or recieve calls or txts, searched online if the imei was blocked and just got msgs sayin "valid" in the end called 3 even though the phone is sim free but was sent out with a new 3 sim, they told me it had been blacklisted as a fraud case and the phone will never work and to bin the phone. This gave me a challenge, brought a 2nd phone from the states with a broken screen (US blacklisted imei can sometimes work in the uk) chamged the boards and now have a working s4

Send over your IMEI in PM and I can check whether it is blocked or not.

Repair Samsung Galaxy S4 IMEI – Fix Galaxy S4 GT 19505 IMEI error

After repair my phone from bad boot, as it was stuck on the attached image i repair it through kies. but now it's showing IMEI problem. it's showing NULL

That's forced download mode. First thing you need to do is flash a stock rom (preferably for your carrier) with Odin. Then, if you're lucky, you may get your IMEI back. If you don't & you don't have an EFS backup, it's either a service centre or local mobile repair shop job.

That was only for samsung galaxy s4 I9500 not for I9505.

I had this problem when I first got my s4 I flashed a ROM everything went fine I booted up and imei was null, so what worked for me was booting back into recovery and wipe everything and restored my backup and all was good again!!

No one that is smart will share their IMEI code with an other person. I would highly recommend that nobody should share their /efs backup.

A bundle of thanks dear, for nice suggestions and advice,
i hope , everyone will listen to you.

I hope they do, because nobody should share their efs.
If you don't have backup then you should get acces to a samsung box: http://z3x-team.com/
If that doesn't work then you have damaged hardware.

the only way is to use KDZ method

any solution I have this problem also, went back to stock kdz method and tot method nothing works. It also keeps rebooting every 20 seconds.

I tried a few different things for a few days and I couldn't fix it so I took it in and they ordered me another G2. My issue is that I wiped my phone clean and lost twrp. I had a backup efs. Good luck

to be safe, next time please upload your efs backup to other storage like Dropbox or something similar..

Yep. This is for next time.

Honestly, you'd need some one to send you their EFS backup (who's on the same carrier and model). Then you'd need to extract it. Then edit it to replace their data with yours.
But I don't think your going to find anyone willing to do that. As it's a HUGE risk to them. So I think your only bet it to to a warranty or repair 'call' with lg if not your carrier.

Permanent no service? No connectivity?

Well i was trying to to flash a new rom on my D802 and accidentaly i deleted everything... a full wipe from phone menu ( not recovery )
Since there was absolutely nothing on the hard drive anymore ( i assume) Phils TWM coudnt find any folders .. i had to push roms to the phone through adb now the problem is that no matter what rom i install i get no connectivity/no service .. cant recieve any calls or use data... only wifi...
I tried re flashing...
Stock rom
Paranoid rom
G flex rom
Stock kernal and peak 5.2 kernal
Nothing has worked? How do i restore connectivity to my phone? Thanks

You have a problem.. Your EFS folder was probably wiped
I guess you could reflash your kdz and bring it into the service centre?

I bought this phone through Kogan shipped from hongkong... This will take weeks, perhaps months... I am not even good with reverting phone back to stock as if never happened...
Is there any other way for me to fix it myself?

Anyone.?

there are plenty of guides on xda on how to revert to stock. search these forums and read carefully. you will be back up in no time. there is also a thread on stock modems also. give it a whirl

Try irc. Channel. #LG-g2. May find a few folks who can help or lead you in the right direction. Assuming you didn't back up your efs ?

Warranty service?

Yeah, if you wipe your EFS, flashing back to stock wont help. The EFS partition contains files individual to each device, you will probably have to return it for repair man D:

I've had the same problem too, my SIM card doesn't seem to be reading on my phone either; and it definitely a functional sim.

I'm sorry, xda mail somehow has been going to my spam folder.
Anyway I am not familiar with this issue, but perhaps you can restore your stock rom via flashtool, then call LG and tell them that you don't know why this happened Oh and modems are distinct from EFS I think (at least that's my understanding)
Your main problem will be the shipping though
I found this thread for the lg optimus G though - http://forum.xda-developers.com/showthread.php?t=2161498. Perhaps try PM-ing autoprime?

Same Problem
I also am in this EXACT same position. Still havent found a resolution quite yet. I am in correspondence with Shellnut the guy who actually wrote the freegee app that uses loki to flash cwm and twrp. He said that only cdma phones need efs, that the gsm phones didnt need it. This was new information to me. I haven't heard back from him quite yet as he informed me my phone wasnt bricked and that they would help me get back up and running. I know he is extremely busy. I have also been hearing that you can possibly use lg qpst to manually write your imei, looking into this now.
I would love to not have to take the risk of sending it in. Would love to just fix it.

i'm in the exact same position right now. Hunting the threads for a fix. I will be going back to Hong kong in 2 weeks time for 2 days, not sure if thats sufficient time for LG to get it fixed.
Hopefully we can find a solution soon!
