[Q] Insert Sim to Access Network Service.. IMEI Null

Hey Guys,
I have an AT&T Model SGH-1317 Note 2. For use on other networks, I unlocked the phone using the *#197328640# menu option. However, the phone failed to start the hot spot stating Mobile data was unavailable or Invalid Sim. However, I am able to tether perfectly using the same sim on an another S3 so I was sure its nothing to do with the sim or network operator settings.
I looked up and found XDA website with tons of information. I assumed my phone was locked by AT&T. Hence, I rooted the phone using CF-Auto-Root, backed up complete data using Titanium and using Rom Manager I installed the Crash Aroma 4.1.2 Rom. I wiped the data and cache 3 times as suggested. However, after the boot I am unable to connect to any mobile network. A Click on Mobile Network says "Insert Sim Card to Access Network Services". Dialling for IMEI number prompt a Null.
During Installation I noticed the Crash ROM has overwritten the Radio.. and I am assuming this is were the problem lies. but I leave it you experts.. Request Help!
Sunil.

What carrier are you using the device on?

Am currently on Du - A network in Dubai, UAE. I have been reading more forum information and some suggest that this may be related to the EFS folder getting corrupted which may cause the IMEI number to fail. Some suggest that there are software to rebuild this information by using the IMEI number behind the handset..
I also noted that my phone model has also changed to GT-7100 instead of SGH-1317, Wonder if the Crash ROM was apt?
Would you suggest installing a Jedi Rom specifically built for SGH-1317... or is the damage already done?

Back Online
Since I found no replies.. I had no choice but to give it to the Pros.. I handed my phone day to one of the Unlocking experts at a mobile store… He was confident that his technicians would resolve this. But after 2 Days, they have given up.. He suggested the phone would fetch me US$ 10 if someone used it as a demo unit at a mobile shop..
I was sure this was something to do with the Modem, IMEI and the all important NV folder. I was able to find a Stock ROM for the SGH-1317 and I also found a link at XDA about using EFS pro to change the IMEI.
Using Odin software, I flashed the phone with the stock rom. Unfortunately, there was one error when it tried to communicated on com1. Having no choice, I continued. Restarting got the AT&T style boot but it again froze on the Samsung screen. Dreading the communication error, I restarted several times with no results. Finally I realised if would be due to the cache and user data. I reset the phone to factor settings wiping out the user data and Whola.. The phone sprang back up..
Lessons learnt.. Backup your rom and data before playing with custom roms. Read Read Read and don’t flash in the middle of the night..
Since I am back online, I plan to stick to the stock and crappy 4.1.1 with all the AT&T dead weight. Will live without the ability to Tether until my fingers get warmer.. It won’t be long as I am already bit by the Custom Rom Devil..
Don't Give Up Easy..:good::victory:

Please I am having the very exact same issue and can't seem to have it fixed
Using CMW I also flashed it back to stock rom, didnt have any problem or errors doing it but im still getting No SIM Inserted. I have deleted cache and user data several times... Tried flashing CM10 and CrashRom see if they made a difference and still No Sim Inserted... tried 3 different kernels and still same issue

I have the exact same problem since yesterday. I've tried everything and anything to no avail. I'm very close to returning the phone.
I would really appreciate any input.

Same issue
I flashed crash rom 4.5, over the stock kernel and it gave me that same message. I've tried everything I could think of, which included everything in this thread to no avail... any further advice would be greatly appreciated.

Your username suggests that you have the N7100 device ??
If so. ..you are in the wrong place for support. ..As this is the SGH-I317 section.
If you are showing IMEI NULL with no baseband you may have to restore your backup image to correct the problem. .
If no backup image exists. ..you will need to flash a factory N7100 image from your section.
Look for the return to stock thread for your specific device and that should fix you up...
The CF AUTO ROOT files are device specific. ..so I hope you haven't damaged the partitions.
Good luck. ..g
Edit:
This will help. ..and will place you in the right section. ..
Just go to page 1...good

Reboot every 3 minutes+sim error

Hi, I've been a member here since 2008 and this is the first time I'm actually stuck with a problem.
I got my hands on a friends Note II GT N 7105 ( LTE intl version) and its been flashed 13 times. (He bought it from someone) Had adam kernel and wanam rom and reboots every 3 minutes even on standby. Also the IMEI disappears sometimes and appears on reboot. sim does not work at all. No calls.
I've installed paranoid android and its still reboots and sim doesn't work. There's some solutions to IMEI here on xda but I didn't come across any that had IMEI status as unknown and then to have it available again after a reboot or after i"fix permision". Plus the rebooting doesn't go away by flashing a different ROM. So I suspect something else is causing this problem.
What are my options here? Try going back to a stock ROM to fix this rebooting and hopefully fixes the sim in one go? If there's a chance I'll try that.
And here's a snapshot

well that would be the best choice as of now to go stock and see if the prob persist then definitely it would be a hardware issue just dwonload a firmware from sammobile the n7105 version
or give a try here as u must be having a custom recovery now http://forum.xda-developers.com/showthread.php?t=2228921

Sometimes it's related to the kernel (i had the same issue on an Nexus 4)
Flash a stock rom, and see if the problem persist

Thanks guys. that's reassuring. I'll try the stock.

Didn't work. Its not rebooting atleast. I read somewhere flashing the ROM specific to the country worked for someone with sim issue.

Okay, I need some serious help with my phone.

After running on a stock ROM(but rooted /w TWRP), I decided that I wanted to install a custom ROM so that I could tether if needed. Well, big mistake. I wiped stock and accidentally wiped my stock backup when going to flash a custom ROM and so far I've tried XenonHD, Jedi X19, IllusionROM, and now I'm on a Stock-Tweaked. So far, every single ROM has caused massive delays in receiving SMS messages and syncs from stuff like gmail.
Data is definitely working, and i've tried both the epc.tmobile.com and fast.tmobile.com APNs but my phone keeps hanging when it trys to send some texts and, if I have texts "waiting" to be delivered to my phone, I only receive them once I turn on my phone screen or only if the screen is on. So what the hell is going on here?

Don't mess around with roms and flash the stock-root injected one via Odin.

Download goo to install latest twrp and then download stock ROM for your device, wipe first 4 options not internal or external and not otg USB at least 3 full wipes then flash stock ROM and wait and you should b good

I installed the stock rom via Odin and still having this issue. =/

It seems that if I go to 4G/3G/2G mode only the issue doesn't persist. Or at least not as much. But then I can't use LTE! =/

Call tmobile tell him you did a factory reset on your phone and that you're having this problem and they will reset the network on their side. This happened to me before in the past and a quick call to them fix my problem. Hope this helps

I just had the same exact issue in the Pittsburgh area. I had to replace my sim card and now all is well.

In Odin uncheck reboot phone before you start, reboot manually and flash twice.

Wifi won't turn on

Hi guys. So about 1 week ago I finally let my s4 mini I9195 Do the update its been wantng to do for a while. Turns out when the update completed and the phone was turned back on again I couldnt connect to wifi, just press the toggle and it does nothing. So ive been lurking the web for solutions and done around these:
-Taking battery out various times and in diferent situations
-http://forum.xda-developers.com/showthread.php?t=2364980 did that even though I have no idea what rooting is and such though Ive read about it 1000x , just dont get why you do that or why there are so many ways and such
- wiped cache/ returned to manufacturer settings also a few times
So, by this point I have really no idea how to fix this guys and its been a pain because I am in erasmus and could really use the wifi. I really apreciate your time for reading this thread and hope that you are able to help. Awaiting your sugestions
Thanks

What you're describing is a very typical issue: the firmware wasn't updated completely (e. g. modem not updated). Solution: flash the firmware again with Odin.

Hey man, thanks for the reply. Can you give me a little more info on how to do that procedure?

Search for Odin (v3.09 or so). Check your firmware version and download it at Sammobile.com.
And use the search for further information.

Hey man thanks again for the reply.
I was doing this http://forum.xda-developers.com/galaxy-s4-mini/help/to-stock-firmware-choosing-problem-t2968295 but near the end it fails for some reason... any idea why?
So I tried it again and this just happened.. Kies wont even recognize.

If you are already on Kitkat you need Kies 3.
Have you probably tried to flash an JB firmware?
Search at Sammobile for the latest firmware for your country and network provider and flash it with Odin.

Hi guys,
i have a similar problem. I flash many time a couple of ROM (CM11 - slimkat) but the wifi doesn't turn on and also the cellular network and the bluetooth don't work...
In the last days i had many problem with my phone because i make a mistake during the flash (on odin) of a stock rom.
Do you have any suggestion?
Thanks a lot

I had the same problem. Wi-Fi didn't work after uploading KK firmware for my country (while to my surprise KK firmware for Belgium worked ok). I tried 3 times to upload KK firmware (XEO, anr PLS) via Odin 3.09 with the same effect (no way to turn on Wi-Fi). Then I used Odin 3.06 and it worked for me (I was able to turn on Wi-Fi without any problem - strange but it had worked). So try to use older ver. of Odin first.
