Help recovering null IMEI on AT&T Samsung S3. - Android Q&A, Help & Troubleshooting

[Not sure if I am in the right spot in XDA. I am still trying to learn how to navigate the forms: p ]
I have a blank IMEI. I was running CM 12.1 and then I went back to the stock ROM thinking that would work. I tried to get into the service mode via the keypad but it's blank. I do not have the proper cables to connect my phone to my PC.

Samsung Galaxy S2 GT-9100m Bricked? :(

So I inherited this wonderful phone not knowing anything about it. Basically I wanted to put ICS on it but I can't...
- Computers do not detect it via USB when plugged in now (it did before). It does charge perfectly though so it's not a connection issue
- Can connect to KIES via Wi-Fi
- Download mode gets stuck. It just says Downloading... and stays there
The phone was originally Bell Canada but it's unlocked and works with my Rogers SIM.
It's currently running Android Version 2.3.3 on Baseband I9100MUGKG2
Kernel Version 2.6.35.7-I9100MUGKG2-CL371789 [email protected] #2
Build Number GINGERBREAD.UGKG2
*#1234*
PDA: I9100MUGKG2
PHONE: I91000MUGK2
CSC: I9100MBMCKG2
BUILD INFO: TUE JUL 12 10:19:43 KST 2011
The phone actually runs fine and all the regular cellular services work just fine. I just can update it to ICS or connect it to a computer USB (to transfer files etc. or do whatever).
What can I do to correct this? Or is this thing stuck on this OS version and the way it is forever?
Thanks in advance
I'd like to add that in upload mode the custom binary count is set to 1. I think whoever unlocked it before did a doozy on it

so the kernel says to me, you arent rooted or are you ?
did you try a firmware from sammobile ?
get a firmware from sammobile and connect your phone via usb and go to download mode
flash it via Odin3 v3.04, drop the one file to PDA
I am rooted and the firmware i am using is 4.0.4 nordic.

Dids your baseband and imei disappear as a result of you repairing the screen ? Have you tried to flash a stock rom via odin?

[Q] Restricted access changed - MT6575 S4 Clone

Hi,
I purchased a MT6575 S4 Clone from abroad.
I noticed that with supplied IMEI number restricted access changed message would appear and there would be no connection to my UK mobile network.
Afters pending numerous hours researching and failed attempts to change to change from GSM to WCDMA only - even using apps such as mobileuncle etc.
I changed the IMEI number to another S4 clone I purchased and this appeared to have temporarily resolved the problem.
It connected to my UK mobile network and the phones voice calls etc worked.
However 24 hours later I noticed that every 3 minutes or so it would revert back to restricted access changed message and no network and then back again to the mobile network.
I don't want to have to keep entering new IMEI numbers every 24 hours or so for the mobile to work.
Although I noticed the other S4 clone appears to do something with auto generates new IMEI numbers by itself.
Can someone help me resolve this with a permanent fix please?
I would be willing to install a new firmware etc if basic instructions are provided which include backing up?
Ideally keeping the workable S4 theme and features.
I did briefly try MTKdroidTools and backing up did not appear to work on there.

Imei Null/null

Hi
Its been 5 years that i have not used my Samsung galaxy s3, because i did some rooting thing and i was broke . Now after 5 years i have found my Galaxy s3 under a drawer and i seriously want to use it again.
Info i have -- 1) Model number - GT-I9300
2) Andriod Verson - 4.1.1
3) Baseband Version - Unknown
4) build Number - JRO03C.I9300XXDLH6
5) Kernel Version - 3.0.31-61691

6) IMEI- Null/ Null
7) ServiceMode - Empty (blank Screen with servicemode written on the top)
I have read few posts from here and there and tried doing the servicemode thing but i was unable to do any thing as my servicemode screen was blank.
when i type *7465625*638*# It prompts me to "personalization" screen where it says " Network Lock MCC/MNC [Space to write] and Control Key [space to write]"
If some one can help that would be so great. I think i did a poor job in explaining. Please ask me what ever is required and ill get onto it.. But trust me i read most of the threads and was unable to understand what to do.
I did a factory reset to get that "servicemode" screen to work but it did not work
You're in the wrong forum This one is about the Tab S3, tablet and not phone... You're looking for this one:
