I have a Samsung Galaxy S3 (I-747) Using Rom Manager for first time I backed up and immediately checked how the restore would work. Lots of stop errors after restore so went back to boot menu for recovery and that worked. First I noticed sim card didn't work and no IMEI number ATT told me. There is no baseband either or any kind of IMEI backed up. Found a factory restore from one of these XDA forums. Process worked but no baseband and cant use sim still. Not bricked yet but want to learn more because i want custom rom knowledge.
Hi,
Here is a similar thread you can read through and hopefully it helps... You could post there also,

So I recently flashed the CM10 M2 rom on my verizon GS3 and it worked good for a week. Now I can't get any service on the phone.(calls, internet, etc).
I flashed it back to bone stock using Odin and still didn't do the trick. I thought it might be the SIM card but I tested it with my old Droid Razr and it worked fine. Any solutions? I really want this phone functioning again. thank you
Kinda new to Samsung and Verizon but from what I read, u may have list your imei, you can look up tutorials on you tube on how to restore it if u backed it up, or how to install default ones. Happened to me and I had to do a factory reset and re root

still in need of help I noticed my IMEI was at 0 so went through a long process to restore it. Now I do have a number under "IMEI" but mobile network still isn't working. I'm currently running stock everything. please and thank you
Well if your like me, you now believe you have a $700 brick. Well I had t he same issue, and I'm rolling done the highway typing this post on my phone. Just fixed it today in fact. This is what I did to fix it. I have a vzw sgs3. Flash it to stock. Flash stock modem fw. Search the forum for restore imei guide tool. Follo those instructions and you'll download a file with a panda icon. after that, when it turns on you will still have no service. This is ok. Search the forums for SIM reprovision. One of the posts tells you to back up everthing including your internal sd. Do that if you want your stuff. Then it will tell you to dial *2767*8858#. (I know these are the wrong numbers but they are in the *xxxx*xxxx# format and it starts with *27.) This should do it.when it reboots it's like a factory reset. But it fixes it. Oh and I also had Verizon give me a new SIM. To 're cap... search Guide imei restore tool and SIM provision.hope this helps.

I would like to first thank you for your input. Although i had that panda icon program i used a different program to restore my imei as well as my eri. After doing that i thought i finally fixed it then realized im still missing some of the numbers under phone status such as MIN. PRL version and ICCID. does the sim reprovision fix this.
Thank you all who have gave me advice to fix this problem. I finally got it fixed and i can't be happier. After going through circles restoring my IMEI and PRL it still wasn't working. What did the trick was dialing *2767*3855# which did a factory reset. My mobile is working again!!!!!!!!!!!!!:highfive:
Hello,
I started with Galaxy Note 2- i317M (rogers, canada), rooted with DN3 V4 beta installed. But I wanted to try DN4, so I created a back-up using TWRP and tried installing DN4. However, I later realized that it is not for the LTE versions yet and phone did not recognize SIM anymore. So I wiped the data and tried installing dn3 v5.5, but the phone still did not connect.
Losing all hope I installed DNv4 again, but it still did not work. So i finally just tried restoring from the back-up I made using TWRP. Everything in the phone is same except no network.
Finally I tried restoring from back-up after doing a complete wipe of internal storage and everything except the external card. But still the error does not go away. I researched more about the error and the fact that my imei shows up as null/null. I used the instructions of using EFS professional, but it did not work. The model number in my phone now shows up as SM-G900F and baseband shows as unknown, and it shows DN3V5 Rom despite the clean-up and restoring from DN3V4.
Any guidance available on this please...I need specific steps because after 12 hour search and try-outs I am lost now.....
UPDATE:
Solved it! Here is the solution for anyone in this problem
http://forum.xda-developers.com/showpost.php?p=46231268&postcount=4
worked like a charm.. No reason to throw this and get a new phone
I have had this problem. It didn't happen whilst flashing though. My imei number is now a generic one and I had no efs backup. After 5 days of trying everything I can find I'm giving up. My note 2 is dead as far as I'm concerned. As far as I'm aware to get my imei back I'll have to send it for repair so I'll buy another phone and not a Samsung
I don`t think your phones are dead. I didn`t try it personally, but I`m sure you can restore your EFS back. Just you need to do some research, maybe you could start here:
https://www.google.ro/?gws_rd=ssl#safe=off&q=how+to+recover+efs+folder
Do not give up, read on end you will eventually do it! And, by the way, next time maybe you don`t forget to back up before doing anything to your phone!

I did back up. with both titanium backup and twrp but it is not working. And I dont think I will give up. I will format is all together and start over if i have to.
Do you think it will work if I format it entirely and start over?

Glad to see you solved it!
Phone was originally bone stock, I then rooted & installed TWRP recovery, booted into TWRP and did the Backup option and saved it to SD Card, I then flashed CM 12.1 and used it for a little over a month, trying the various Nightly updates.
I decided to go back to the stock rom I had backed up previously, It restores successfully but when I boot the phone everything is crashing once it hits the home screen, "Unfortunately xxxx has stopped" is seen over and over, I can't load anything, even the settings menu crashes.
I then tried rebooting into TWRP and did Factory reset but when I do this It wont ever get past the Samsung logo on reboot.
Not sure what went wrong with the backup or if Im missing a step, I also tried enabling the verify MD5 check option for the Backup and it says everything is fine.
For now I'm back in CM 12.1, Any ideas appreciated!
Hello and thank you for using XDA Assist.
Your device has a dedicated forum and within that forum you have a Q&A section specifically for your device.
Please try searching within this forum http://forum.xda-developers.com/galaxy-s3-sprint/help and I am sure others have previously experienced the same thing.
You will find the device experts for your Sprint S3 there.
Within that forum you could also find a stock rooted Rom and download and flash that. You do need to know exactly what boot loader your device is running.
Good luck
Ragnar
I have a Note-4 T-Mobile variant(N910T), I have been using Xenon HD and then CM 12.1. After a while when I wanted to go back to stock, and when I flashed stock rom back, the phone was really laggy at first and during setup, there was a popup which said that Factory mode is enabled and I have to switch back to User mode before using it and after a few seconds it disappeared, this happens every time i reboot while in Stock Rom. Somehow after a few minutes, I get the WiFi on again but the keyboard gets stuck after a few presses and phone gets real laggy. After the setup I googled the problem and found out something regarding the EFS Folder, so I rooted it once again and installed ES File explorer and went into EFS and found that it was empty. I tried placing a phone call and it went through and I was also able to use LTE, but when I went to about phone to see IMEI, i saw that the IMEI was wrong, I even tried to setup fingerprints, but it kept saying me to reboot as something was wrong with the fingerprint sensor. Now the weird thing here is that when I am in a Non-touchwiz based Custom Rom, I do not find any lag and the IMEI is correct. I have tried these things already:
Going to EFS and switching Factory mode on, but as i told EFS folder is empty.
Backing up EFS from the custom and restoring when I'm in Stock.
If anyone knows how to fix this, could you please help me?
Thanks!

I originally had Arrow ROM installed and audio calls were not working, so I flashed the modem (when I should've flashed the audio patch) and I lost the mobile network settings and had a null IMEI. This isn't the first time this happens (didn't learn the first time to back up EFS) so I thought it'd be a easy fix. First I flashed the backed up EFS file of my friend's S6 and that didn't work, so then I flashed the stock firmware multiple times and it did nothing. It didn't even delete my data and just had it stuck on a boot logo and everything inwould just have to flash twrp with Odin and just try again but nothing seems to work. Any help or ideas would be greatly appreciated.
