Hi. I think you'll get more help if you ask your question in A-Series 2017 forum. There you'll also find TWRP and root for A520.
The files you refer to is probably the nv_data.bin in /efs. I've read it should be possible to restore imei somehow by using hex-editor but I have no experience in that. I also know some older models had a "hidden" menu where you could perform a NV restore but I don't know if it's possible on newer devices.
Anyway, I wish you best of luck to restore your IMEI and hope you'll find someone who can help you more.

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.

Changing IMEI is illegal and can not be discussed on xda, If you have your original efs folder you may request help restoring that but nothing else

Serial Number (SN) keep resetting to zero (SN: 00000000)

I had completely formatted (including the bootrom) my smartphone (Lenovo K4 Note, variant) using SP-Flash Tool, resulting in loss of IMEI, SN, WiFi address etc. At the time I had almost zero knowledge of the various partitions of the smartphone and was under the impression that re-flashing the stock ROM would fix everything if something goes wrong, hence didn't took the back,only to realize it won't if you have also formatted the boot ROM. Anyways over a period of time i was able to fix all things but the Serial Number (SN) which still shows all zeros (8 bytes).
Currently i am running MM 6.0 but it was formatted when i had Lollipop (5.1) (pre-installed), anyways recently i got hold of correct nvram partition image (shared by one of the member on this site) which i flashed it on my phone. After flashing it (using SP Flash tool as well as through TWRP recovery) my phone started to show correct SN value (not mine but the value stored in the nvram image shared by the member).
Encouraged by this, i hex edited the nvram image and replaced the stored serial number by the original serial number of my phone (ensured all occurrences are replaced in the nvram in fact in the whole ROM dump) and re flashed the nvram image. Unfortunately to my disappointment the serial number is again reset to all zeros.
So can someone please tell me what is going wrong here? What extra information is required to fix it?
Please see there are tons of serial number tutorials on the net and probably i have tried them all ( Even tried after reverting to Lollipop 5.1) but none of them works. The tools mentioned in those tutorials either writes "Barcode Serial Number" (Barcode) which is NOT same as the serial number displayed by Lenovo K4 Note in "about phone" menu. Lenovo seems to be using a custom serial number. Or they do not work with ARM64 Bit MT6753 chipset.
I need to fix this serial number as i wish to sell my phone and go for another model.
Please let me know if you need more information from me.
Thanks in Advance
if you made nandroid backup of stock rom then restore nvram and nvdata in custom recovery and reboot
Thanks for the reply. Unfortunately I didn't created any back up whatsoever.
TWRP doesn't work if you have also formatted the bootrom, which I did (I have updated my query with information)
did anybody got solution of this. hw to change SN in k4 note?
Edit: issue fixed. this thread will help https://forum.xda-developers.com/k3-note/general/restore-sn-form-00000000-to-original-one-t3356401

Null IMEI on Samsung A5

Hi Guys,
This is my first post here and also I am fairly new to android, so I apologize in advance if I violate a forum rule or ask an obvious silly question. Anyway,I Recently, I received a Samsung A5 2016 Dual Sim from my friend which did not boot up. Apparently he had installed an app which caused this situation. Then he had tried to install multiple firmwares with Odin on it without success. Anyway, I received the phone and first strange thing that I found was that product name in download mode was SM-A5108 which was different from A510FD which was on the phones box. This probably was the main reason behind not being able to flash any A510FD firmware on phone. So I flashed a A5108 firmware on it booted up to android. But there was 4 issues there:
1- No baseband version was available.
2- No IMEI information for either of sim card slots and of course not detecting any of sim cards.
3- Very sensible lag and delay on loading apps and working with menus.
4- Also A5108 is apparently available for china region so menu was Chinese and other region specific apps was on it.
I found out the original firmware on it was A510FD so searched a little bit and found out it is possible to restore a backup from A510FD. I downloaded a backup file from internet and restored it using TWRP (Data, System, Boot). After restore, phone booted up with A510FD but once again with null IMEI and also lagging. Right now baseband version is available and device model on about section is A510FD. I know all radio related information is on EFS but I have no EFS backup right now and restoring EFS is not an option. Is there any way to fix IMEI issue now?
I can provide exact build number and any other information about phone and firmwares that I used in case it is required for better troubleshooting.
check you phone model by imei or serial from the box or from back of the phone, if someone messed up that phone is hard to be sure what model is

I forgot to mention there is no IMEI on phone's box or phone itself. But phone's model (A510FD)is printed on box. Also battery is non-removable so not able to check inside of phone for IMEI.
If there is no other option you could remove the back glass panel to see the IMEI number there is a sticker underneath it i replaced the screen of mine and i saw this sticker. You need to be carefull taking off the panel tho cuz you coul rip off the sticker if you're not careful.
Thank you for responding. Okay, Let's suppose I found out IMEI by opening phone's back panel. What is the next step? How could I use these information to recover IMEI to phone? Is there any chance that IMEI information is at EFS partition but due to wrong firmware upgrade it is not working?
