Fix baseband version and imei unknown - General Questions and Answers

Hey guys, this is the first time posting here and I hope my problem will be solved.
Yesterday, I was flashing a bad rom in my Sony Xperia C2305 that didn't work. I'd backup so went to Cwm and recovered my stock rom but after recovery SIM cards were not working, after searching a lot I came to know that baseband version and IMEI were messed up by bad rom and they both are showing unknown till now.
After searching the whole day, I came to know that it can be fixed by flashing ftf firmware so I download both latest and old firmware. But I couldn't flash those firmware with flashtool because of CWM recovery.
So, I tried to remove CWM and get back to stock recovery and I came to know that only odin can do that but there is another problem with odin. It simply needs pda, csc, phone files which I can't even check by dialing *1234# because of SIM error.
Now, if someone can help me to get pda, csc, phone file I can proceed, other than this, I have extracted the ftf file and found recovery-sign.sin file, if somehow it can be converted to img than I can recover my stock recovery with mobile uncle app.
I also tried to write imei with mtk droid tools but it didn't work and not even writing imei with terminal worked.
Except this all, I have also brought volcano box from my friend which can also be useful, I'm checking it out now
Please anyone who knows the solution for my problem please guide me to fix my phone and yes it has still 8 months of warranty but it's rooted might not work.

The only hope you will find here is flashing a stock package as touching the IMEI in any way is illegal and banned here.

Sorry, I didn't know that touching IMEI is banned here so regards flashing, is it possible to flash ftf firmware with CWM, if yes than how?

I've never heard of this before and it seems extreme that you could lose IMEI number just by flashing a custom ROM. What method did you use?
I would have assumed fastboot flashing stock firmware should solve this.

Hi Sorry for late reply but I lost internet connection on Saturday morning.
When I have been doing some stuff in CWM recovery, had system and data partition mounted.
Then done rm -R * in root dir.
At this point I thought that my current dir is tmp.
After this I lost wifi and IMEI.
I manage to sort out wifi but not IMEI code.
Do you know how to fix this?
Since that I have been re-flashing stock rom and CWM rom but none of them help.
Chris
anyone can help to recover IMEI ?
Thanks
Changing/manually setting the IMEI is illegal afaik. And afaik assisting someone with that is also forbidden here on xda. We used to have a similar problem on the phone I came from, and there was a app which let you backup/restore your IMEI. You need to have a backup in order to restore it so this won't really help you...
This is what I'm talking about: http://forum.xda-developers.com/showthread.php?t=1591997
Edit.: There actually seems to be a way to manually set it but I'm not sure if it is device-specific.

You can find your Imei on the back of the phone.
If you google android 4.4 set imei you should find something from technostall which might help you
Good luck
Yes, it's on the battery.

I haven't.
I tried to sole this issues re-flashing with different roms, but after several operations it bricked.
It's totally dead, not charging, in linux I can't see device connected, so i think that is dead.
I bought new one.
Good luck with this problem.

I solved the problem, place to charge the phone, let him take some of the load and flash the original ROM, after that flash CM11, and run perfectmente, I think at first it was because I had done without the SIM, the second time you make with the SIM sunset ...

Yes It Does for most of the devices given you should know the proper method.
Mtk is different. It's not the same thing.
Any news?
Also I think the problem is that the imei is on the phone just not on the OS? (obviously, but...)
Maybe when we all reflashed to the original stock (and countless other stocks) they just didn't have the proper folder to access in order to identify what imei they're assigned?
Because every single time I've tried to manually rewrite the imei to it all the methods I've used are futile. Even the ones specially tailored to the Moto G's hardware SnapDragon - Qualcomm...
restore IMEI by Motorola service?
Same problem for me. I am really interested in some experience about restoring IMEI.
Motorola support phorum owner replied that Motorola service can recover IMEI (not covered by any kind of warranty of course).
I have tried to reflash factory ROM with and without inserted SIM card, but unfortunately no difference.
I have seen looking for solution, that for some people Android system sees IMEI=0, but the IME is still untouched using fastboot mode and "fastboot getvar" CLI command
For me it's empty using the "getvar" command as well.
The official service center in Germany told me that they mustn't repair selfmade imei problems :S
Lost IMEI
You could all try this new method claimed to be working but as I have not lost my IMEI I can't say, please report back if it works for you?

Z3 d6603 Invalid card after downgrading firmware

I send my unlocked and rooted Z3 to the sony repair center. They sent it back unrooted and updated to the latest bell firmware, I didn't check if my SIM worked or not at this point as I had a nandroid backup that I made before sending it in in case they decided to reset everything.
Steps:
Used flashtool to downgrade.
- downgraded phone with D6603_23.0.A.2.93 ftf on the XDA thread, first time bootloop due to drivers I think, reinstalled drivers and second time worked fine.
- ran giofroot exploit. used v3.1
- mounted /system rw with ES Explorer.
- installed Z3 Dualrecovery for locked BL.
Tried to restore my nandroid backup through recovery, system restored ok but got error 255 when restoring data. Bootloops when I tried to turn it on.
Flashed a clean build prerooted 23.4.A.1.232
This is where I noticed the SIM gets an invalid card message. Checked service menu for sim lock
it reads [ ] network 0 so it seems to me like SIM lock is not the problem.
At this point I tried downgrading using flashtool again to start from the beginning but it hasn't worked. Googled this problem but there was no definitive solution in any posts that I have encountered.
Anyone have a clue on what to do? Should I try to update firmware with PC companion and hope it fixes it?

So assuming something got messed up while restoring backup, it should be able to be remedied by flashing, correct?
Yeah, flash a FTF and wipe appslog and cache and boot without doing anything and see if SIM works

If anyone finds this thread later in search, I figured out why this happened to me.
When the repair center sent back my phone, it re-sim locked my phone, I needed to put in my simcard to get the sim unlock prompt and enter my unlock code again before I started downgrading firmware and rooting etc.
I ended up sending it back to repair center and they reset the firmware back to normal - I assume they have more robust repair tools than I do. Thanks everyone for the help.

I saw some threads talking about octoplus box but I still have my efs Backed up my and SN and IMEI still show up.
Please help me I am here I am willing to learn and search online. I've tried everything i've found online.
Hi.
Try to use Smart Switch > Software Update and Initialization to recover your firmware, hopefully you get your network back.
Tell me what happens, gl.
Sent from my SM-G920F using XDA-Developers mobile app
almost same thing on a long thread here, no solution so far:
http://forum.xda-developers.com/galaxy-s6/help/g920f-network-issues-t3291903
I am seriously considering it could be sim reader issue, or some cold solder somwhere on mbo.
My IMEI was also showing in settigs, but when dialed *#0011#, in stack 1, there was "IMEI NG", after write cert operation via octoplus, it says IMEI OK now, but NO SIM, and no mobile networks menu still.
Same like you SIM is detected when inserted or removed, and phone offers restart to access mobile networks, but after restart nothing changes, KNOX tripped by previous owner, phone was in three 3rd party repair shops, where they made even bigger mess than it was, when I brought it to them.
i had the same issue when i upgraded to mm so i sent to shop they had to downgrade it to 5.1.1 and use octobox to fix it
Thanks for replying Legend.
But even though I did the software Initialization in smart switch once before it is not working for me now.
I've tried twenty time while reinstalling and restarting the pc I even tried a different pc I get the same error message every time. "failed to run firmware upgrade unknown error occurred".
any other thing to try?
you could try to restore that backup you have, from when everything worked and then flash 5.1.1. bootloader and modem for that csc via odin before rebooting
According to Smart Switch with your sn it is ILO so you need 5.1.1 bootloader and modem from ILO 4 file fw package.
*I just managed to flash stock 6.0.1 via odin (even though It failed at hidden.img... it boots normally) still no sim card tough.
*I realized that maybe all of this happened because when I flashed stock via smart switch for the first time I didn't have my original s/n so I put one from the internet and it wasn't my region.
meaning I flashed stock of UK and it still worked for a month or so, so that's weird...
*Thank you brenner that is a good idea and I will try now
question how do I extract the bootloader and modem out of the fw? I just open the tar archive and take the boot.img and modem.bin files and flash them as is?
nvm found a guide

There are .tar-s which are single file, and 4 files, the ones with 4 files has separate bl/modem
btw, isnt sn written on back of the phone, along with IMEI?
OK, I've flashed the nandroid stock 5.1.1 (LMY47X.G920FXXU3COJ1) and its bootloader and modem from sammobile.. still doesn't work!!
How can this be? everthing is EXACTLY the way it was when it was working!
and no, my model at least doesn't have the S/N and IMEI written at the back, and I didn't keep the box
any other suggestion anyone?
*also there are so many post in subject if I ever find a solution I will make a guide.
-bump-
still no solution..
I've flashed back to current stock ILO...
Meanwhile looking for a lab with octoplus box, still would love solving this at home
At home or not, I would like to solve it too
Bought a second hand S6 the other day and was working perfectly fine until I carried out the update. Now on 6.0.1 and am getting the exact same problem, my SIM works in every other phone. Has anyone found a solution for this?
Not that I know of, except hw replacement, which cost as a used phone with 1+ years of warranty (6 months warranty on motherboard after replacement, on motherboard only)
But I am willing to donate to whoever finds a solution for it.
No i think your problem is a S/W problem, i have 2 G920F with this problem, one of them is 3 binary and another is 4 binary FW, now i work on it if i can solve this problem i told you here.

[Fixed] My SM-G955U Has No IMEI or Baseband

EDIT:
I was able to fix it! I had to install a custom ROM to obtain root and delete my EFS partition.
So, here is a bit of a story I will try to keep short.
I went to Vietnam and bought a S8+ from there.
It was a US S8+ from Sprint.
I used it fine there but when I came back to states I tried to put my Verizon sim in and it doesn't work.
I don't get any signal. But I am able to see Baseband and IMEI.
So, I tried to use Odin and flash one of the SM-G955U1 Firmware.
Now, my phone is weird and out with no Baseband or IMEI.
So I try to flash back to firmware it was on.
Same thing.
Any ideas why my S8+ is like this?

What happens if you restore from the OEM function?
Try downloading custom recovery and flashing a custom rom. You will lose samsung pay but you might have a working phone it's a chance I would take if it was me. Your baseband is messed up try just flashing your carrier baseband . These are just ideas good luck
Sent from my [device_name] using XDA-Developers Legacy app
If flashing a custom ROM will fix your phone then so will downloading latest official Samsung ROM and flashing via latest Odin .
The second option above would be the best to try unless you're happy to have a custom rom and lose Samsung pay and anything that relies on Knox being functional

Jtag dead phone to life and rewrite IMEI
First of all my phone is the s8+ G955fd, but I am sure that the people that helped me can help most Samsung owners with bricked phones.
My phone ended up being stuck on the first boot screen, I couldn't get into recovery or download mode. I installed TWRP and after that I lost my IMEI numbers( dual sim), so I tried to reflash stock and thats when i became bricked. I searched someone to help and found reference to the Fonefunshop in England. I sent it there and they said that the eMMC chip was bad. I searched for someone who could write to it or put a new one on the motherboard . I found A2Z cellular in Ottawa Canada. They used jtag to restore it to stock and they told me that the Fonefunshop had not opened the phone which is necessary to use jtag as they claimed, so avoid them.
The phone was now back doing everything it should except the IMEI's were null like before. I gave them the original IMEI's and the phone is working like new.
If your Samsung is bricked these guys can probably fix it and it won't cost much to find out.
the SM-G955U has a locked bootloader, so people should not be telling you to flash a custom recovery or custom ROMs. there is only one way to get root on this phone, through the samfail exploit, and safestrap is the only working recovery. I don't believe it supports CDMA networks but I'm not 100% sure on that. I have this device and I'm only aware of GSM carriers using it.
Just an update on this issue. I still don't have a working Baseband or IMEI. Any clues?
I was able to fix it! I had to install a custom ROM to obtain root and delete my EFS partition via ADB.

Be very careful with doing that. It can cause the EFS (the partition that controls IMEI, Mac and a few other things) to be completely corrupted. Which will cause the device to be useless without fixing it.
Now a little heads up. As messing with the IMEI is illegal in many countries (the US being one of them) There are only 2 ways to fix an IMEI issue allowed on XDA.
1. Restore the backed up EFS partition
2. Return it to the OEM to be repaired.
What did you do after you deleted EFS? I can delete in Combination but I dont get the IMEI number back.
Please I need all XDA members assist ,because of I mistake delete EFS with combination file on my G955U VZW , I have null imei number, then I repair it by flash qcn with z3x Samsung tool , but still I have IMEI number but emergency call only is still display without service ,
