Hi there!
I think I may have messed up, I tried flashing Paranoid Android and I booted my phone up to find I had no network. I had a look at the settings and it shows imei, imei sv and phone number as unknown. Is there any way to fix this or have I effectively bricked my phone?
Thanks for any advice you can offer me
Do you have a backup?

baseband version is unknown
1- baseband version is unknown.
2-imei null
the phone is just restarting. someone help me.
Model: D802 32gb open
EFS. Hope you backed it up... if not, search forums, going to take a lot of manual work in diag mode along with a couple other apps via pc port to rewrite your IMEI.

This happened to me a long time ago on my T-Mobile version and I tried everything I could think of but then I used the tool that you'd use to flash back to stock and flashed it to Android 4.4 and it kinda fixed it so now it doesn't restart much might restart every 20 minutes I never looked at it 4 that long becauseiI bought the international version. So android 4.4 doesn't fix the null imei but now I can use my phone as a media device because it doesn't read Sim cards and at least I can connect to wife so yea

Had the same problem like you before. You must have done something that altered the Baseband/Modem. I will assume you haven't made an EFS Backup. What you can do is this, download a stock Firmware and manually flash is. Just be sure that the firmware you will download is meant for your country. After flashing, try to see the IMEI of your phone. If the correct IMEI shows, then try making calls, text and connect to your mobile data. If not, then try flashing any modem meant for GT-i9500. If the problem still persist, then your last option would be to change baseband antennae or worst, replace the board itself which can only be done by technicians which has the proper replacement parts.
Thanks for answering, i flash my device with my country oficial stock room, after that im still having the correct imei but cant make calls, say no service and no registered on network, i have efs backup, but after restore nothing happend =(

Hi.
I have a Xiaomi Mi2S that doesn't connect to any cell networks.
I'm using CyanogenMod 11 nightlies, and after an update the phone lost its IMEI number. I had taken a backup of the NVRAM using EFS Professional, but when I looked for it the files where 0 bytes in length (probably a hard disk problem on my computer)
After trying a lot of stuff (installing stock MIUI, putting the phone in diag mode and installing a bunch of drivers), I managed to restore the IMEI number, but the phone still can't connect to the network.
I have tried a SIM from another company and it doesn't work. And my SIM works correctly in other phones, so I think that is not a SIM problem.
I don't know what to do... I tried flashing different ROMS, tried flashing a new baseband radio, but I can't get it to work! Is the phone lost???
Can anyone help me? I would appreciate it very much!!!!:crying:

Hello,
did you have some informations ? I have the same issue with my MI4... No more network after a flash of CM12... I hope you found a solution.
thanks.
Hi everyone,
My S4 has lost its IMEI, and here is my situation.
I was using Prism v14 (http://forum.xda-developers.com/showthread.php?t=2537515), and it was totally fine. Last night, I tried to flash a new S6 port rom, this http://forum.xda-developers.com/galaxy-s4/i9500-develop/rom-aurora-s6-port-t3063408, and my fone lost its signal. The signal icon is still full, but it was only available at emergency calls. When i check, IMEI and Serial number were still there. I tried flashing the Prism v14 again, didnt fix it.
Then I took my fone to the care center and left it there for a few hours. When i come back, they told me that, they flashed it back to stock, and when i ceck, the IMEI was gone. They explained that, when I flashed the S6 port rom, the real IMEI was gone, it was only the fake IMEI from the rom that I saw (didnt know if this was true).
So now im asking for any possible help/solution. I was bad to forget backing up my EFS. So i wonder if I can use someone else's EFS to restore? If yes, it would be great if any one can share with me the EFS backup.
Thank you for reading and please excuse my bad English.
The EFS folder doesn't store the IMEI, despite having an IMEI folder, thus it won't help you. nv_data.bin also will not be found there, if my S4 is any indicator, but will be found in the hidden partitions.
You'll need to try flashing the baseband for your device again, and to do that you're going to have to download a copy of the ROM, which should be found on the forums here. Sometimes the baseband needs to be flashed twice for everything to properly work. I can only speculate why that is, but I believe it to be due to having two hidden partitions for the baseband. When the baseband is copied into the first partition it isn't copied into the second, resulting in a mismatch. Flashing the baseband a second time writes the baseband to the second partition, and everything functions correctly.
If flashing the modem again does not work, getting your IMEI back will require using methods that cannot be discussed here on XDA.
Hello all, I tried the 4.4 nandroid from the development section which was supposed to update my 16gb phone to 4.4. The phone does in fact run 4.4 now but refuses to connect to any mobile networks and says the IMEI Is invalid. Upon going into settings and checking the status, the IMEI shows as unknown.
I have looked for a solution to this but I cannot get this phone into diagnostic mode no matter what I try. Can anybody guide me into fixing my IMEI? I am not trying to change the IMEI for a new one I just want to restore the original IMEI so the phone can work again.
Please help me.
