HELP! Corrupt IMEI, baseband, Serial Numer on S4 I9505

Hi all,
Sorry for the noob question but I have tried most of the repair suggestions in this forum all still could not get back the IMEI, Baseband, and serial number of the handset. Is there a way to program the original IMEI and serial number back into my Galaxy S4 I9505?
The handset had Hong Kong firmware 4.4.2 but with null IMEI, null baseband and wierd serial number. The handset is not IMEI blocked in Australia which I am trying to get it to work.
Would Chimera or Z3x software do this? Kies could not detect the handset for firmware update.
Thanks.

Already tried that. Flashed with stock Hong Kong firmware, modem only, etc and did not fix it.
Is there a way to find out the which is the original firmware for the phone as the previous owner might have flashed it with the wrong firmware?
:crying:

Go here and enter your IMEI. The result should pop up with a great deal of information about your device. Post the result, not including the IMEI itself, and we can figure this out for you.

If your IMEI just disappeared without you doing anything, then chances are you got a hardware failure and the your EMMC chip needs to be replaced.

Hi all,
I have re-flowed the MMC chip successfully. Is there a way to restore the IMEI and baseband without the nv-backup file?
Thanks :crying::crying:

Only if you used Wanam's EFS Backup tool to make a backup. It backs up not just the EFS partition, but the modem partitions and a few other hidden partitions as well. Otherwise you need to use methods we can't discuss on XDA to fix it.

How do I find out the if the modem and IMEI info were still there and not completely erased or gone by the previous owner. I received it with null/null IMEI baseband fault.

You already replaced the modem as it was suggested by someone upthread. That would take care of the modem. There's no way to know whether the IMEI is present or not. It probably isn't present, in which case it needs to be rewritten.

I think the IMEI info is lost so I would need to rewritten as I don't an NV_backup copy

The NV backup isn't present in the /efs folder on Android 4.4.2, at least from what I've witnessed on my own device. That's why I've switched to using Wanam's EFS Backup tool from Samsung Tool as it backs up the hidden modem and EFS partitions where the IMEI actually is stored.
If the IMEI is completely lost, you'll have to take the phone to Samsung for service. As mentioned upthread, there are other methods to fix this, but they can't be discussed here.

Thanks, in my case the modem and IMEI are already corrupted without an EFS backup so how can they be restored except for re-writting the IMEI ? I will look into Wanam's EFS Backup tool to see if I can salvage this mainboard.

no. the only way to fix it use a octupus box but unfortunately it is illegal in many countries as it can be used to restore or change imei number.

Lost baseband/IMEI using Odin?
Did you used latest version of Odin 3,Downloaded CORRECT/Same firmware for your S5? Is latest firmware? Flashed via "AP" Option and Mark Auto reboot, F-Reset time and NAND Erase, Only This Options in flashing?

Downgrade to Stock 4.4 kitkat and root.. Install Xposed framework... inside Xposed you will find imei changer... download & install. after that turn off phone remove battary and you will see IMEI number..
write somwhere and turn phone.. open imei changer and enter original imei number.. click save and restart phone... now you can update to any firmware version...

Lost my IMEI, IMEI 0000000000 and i did not backup EFS folder. GS4 SHV-E300K Korean

okay so i tried to install xposed framework via recovery since it gave me an error during normal install, the device rebooted the got stuck in a bootloop, i flashed the latest rom for the shv-e300k from sammobile, everything worked great and the device booted into touchwiz, but there was 'No service' and the phone didnt connect to mobile network, when i dial *#06# i get IMEI 0000000000000.
i tried flashing different stock and custom roms, but nothing worked.. i tried a method to restore imei by copying EFS folder and using the .nvdata file, problem is there is not .nvdata in my EFS folder, I even tried installing cyanogenmod 13 and installing xposed framework on it together with the IMEI changer module, I typed my IMEI there but still no service..
PLEASE HELP!!!!!

The NV Data no longer lives in the EFS folder but is located in a hidden partition you cannot access. Wanam Partition Backup could have backed up and restored that partition for you if you had used it, but since you didn't, you'll have to take the phone to a service center and have the service center restore the IMEI.

can you please tell me how to get to that partition using wanam partition backup ? and what is the partiton called ?

All the app does is back up and restore that partition. It doesn't let you access that partition, and besides, it's too late anyway. Your IMEI is gone, and using the app now would only back up what you currently have.
This device needs to be taken to the service center.

same problem here

respected dev. i have the same problem. i flash a different firmware and now my phone baseband is unknown and imei is null. after a few days of checking its still not working. i have recovered its last working condition details as you can see in the photo attached

If restoring stock firmware does not restore the imei, you will probably have to have it fixed by jtag service or repaired using a programming box like an octopus box: http://octopusbox.com

Or have the phone serviced by Samsung, as discussing tools to rewrite IMEI I don't think is permitted on XDA.

I think discussions about restoring the original imei to the original motherboard/phone is okay but discussion about changing imei or serial number to something other than the original is not permitted.

Could you please check this.

check this but before this i want to ask that can i flash other firmware so that i can get baseband back. if i get baseband then i will use the above software to install the New Imei on the Phone. Tomorrow i will try every possible method to get back the phone to life and then if i fail, i will take it to the service center but if there is any possible way that you can help us so please assist and we will appreciate your assistance. thanks Regard Muhammad Ismail

That Xposed module won't work as what it does is spoof the IMEI for apps that have reading or sending the IMEI in their permissions. It does not change the existing IMEI and cannot be used to restore a lost IMEI. It requires the Xposed framework to function in the first place, which should give you a really big clue that this won't work.
If you want to waste the time and try it I'm not going to stop you, but the resolution to the problem requires tools only Samsung has. Android can't rewrite the IMEI as the IMEI is part of the phone's low-level firmware that Android cannot touch.

check your phone box if you have lost the imei

IMEI Writing I9500

Yesterday I decided to Upgrade my S4 i9500 to 6.0, the rom is amazing (despite the amount of battery it consumes) but when trying to acces to the imei (*#06#) it shows 0049990106..... as you might notice not my imei, I did this EFS.img backup, via terminal but now I am not able to restore it via terminal, I rooted the phone but I just can't do it. i wonder If i can Write the imei via PC or APK since i have it wrote down in my phone bill but obviously now the warranty is totally void... so I have the efs but I can't restore it (it shows succed restoration but nothing happens, no imei change) and i have the IMEI number and i really need help what can I do?

If it were that simple to change the IMEI, then anyone could just borrow a phone from somebody, get the IMEI, and do some mischief with that IMEI.

Did you restore the imei to a stock ROM?

Take the device to a service center and have them fix it. You backed up the EFS partition, but nv_data, which contains the IMEI, is no longer stored there. Thus the IMEI was not backed up, which is why you can't restore it.

NOT REGISTERED ON NETWORK AFTER UPDATING ROM

Hello, everyone! This is my first post on XDA so sorry if it ain't in the right place.
So... What I did is manually updated my S8 to Android 9 through Odin but it isn't receiving signal and it shows that I'm not registered on network. I already tried everything I could but I can't solve this issue. Can someone help me?
Edit: my phone was working perfectly before I ruined it all.
IMEI ok, signal ok, it's not a hardware problem. I've tried configuring APNs and the ROM is the correct for my phone, country and carrier. I just don't know what is wrong. Thanks for all the replies

Try these:
Reconfigure APN's in the cellular data settings.
Check if your phone has IMEI, if you flash-all you may also lose the EFS partition. If so you have to restore your EFS partition backup.
If you flashed the wrong carrier's android, you'll have to flash the correct one. For example your phone is T-Mobile, but you flashed AT&T version.
Goodluck.

Hello! Thanks for commenting.
I tried configuring APNs but it still not working.
I'm sure I flashed the correct ROM.
I think I lost the EFS partition as you say, since I didn't backed up anything (I'm feeling silly). How do I restore my EFS partition? Thanks again!

Check your device IMEI first if it says null or unknown or something similar then you indeed have corrupted EFS.
To check your device IMEI, open dialer then dial *#06#
As for how to fix this, as far as I know without a backup you can't. EFS partition is automatically backed up in any nandroid backup made by TWRP.
You can try XPOSED IMEI changer or if magisk has a similar module.

I honestly have no idea man, sorry not being of much help.
All I can help with is provide you with this tool.
On a side note the image you put there is completely useless and it only exposes your IMEI. The barcode also contains info about your IMEI.
Goodluck.

I saw your thread and my guess is that your device is network locked by IMEI, if you contact your network provider they can confirm it for you otherwise try a different sim card and see if it works.

perhaps you need to reflash the modem.img on your device, you can get it from here

Did you find a fix for this issue? I've same issue with my S8+. Phone keeps saying there is a Network or SIM Card error on any Lineage ROM (with Android 12 or 13).
