i don't have a backup !!!!

take it to service center (legal) or a repairer who will write a new EFS folder (illegal)
Original post here
you need special hardware to recreate the efs folder and rewrite the imei.. changing the imei is illegal on most countries so its obvious that it wont be easy to change... the service center has the tools to recreate the efs folder... flashing software will not fix the corrupted efs and would probably make it even worse...
our methods for flashing:
computer ----> phone
specialists and service center:
computer ----> "special hardware" ----> phone
you can do a search on the internet on what "special hardware" they use but i doubt that that would be for sale in a country where changing imei is illegal
software alone cannot recreate the efs folder nor write a new imei.. all you can do without the hardware is try to recover your corrupted efs if still possible.. if it comes to the point that it needs to be recreated or rewritten then it would be impossible without the said hardware

just give the software that can writte new EFS folder and his contenente because it is not illegal in nord affrica lool :laugh:

The i9305 has a Qualcomm modem, unlike the i9500 (which is completely Exynos-based). Any IMEI-related stuff needs to be done with QPST.
Follow this guide to (in the future) make a backup and be able to restore it (IGNORE THE i337 FILE AS THAT'S FOR THE US AT&T MODEL AND WON'T RESTORE YOUR IMEI):
http://galaxys4root.com/galaxy-s4-t...aws-bands-on-att-galaxy-s4-sgh-i337sgh-i337m/
Try this tool for injecting the IMEI number into the backup so that you can restore it to the phone afterwards. The US and Canadian Galaxy S4s are based off of the i9505 (and i9505 ROMs will work on them) so this tool should work for you:

Question How to restore IMEI + mac address?

Hello!
I wanted to change my MIUI version from global to eu, so I installed TWRP and flashed the rom. The problem is that somehow while doing this it wiped the IMEI, and wifi/bluetooth mac address. (so it doesn't see sim cards, and wifi networks)
Is there any way to restore the factory IMEI + the mac addresses? (I have them written down, and on the box)
And how to make sure that I don't wipe these things again?

Seems so. Don't know if it can even be restored or not if you have backup.

And if I haven't backed it up, is there a way to download it? Or is there any other way? Or is my phone broken?

Question Asus Rog5 imei Null No network

I make a software by QFIL - after that imei null
I Have The Box with IMEI but I don't Know how to restore It ??
there any solution to fix the network?

You need to hex edit your IMEI into your QCN file and flash it back to the device. Also from QFIL.

There are a lot of guides on XDA and elsewhere for the steps. However you need to first secure a working QCN file if you don't have a backup of your own and know the IMEIs in that file, so you can locate and overwrite with your own IMEI. Without that, you won't get far... I don't have a QCN file for this device on hand, maybe someone else here does and an share with you...

Is there a solution to unlock bootloader always Error11003

@Andrologic
Hey! I have been long trying to recover my nulled IMEI on ROG5. Every single tutorial I can find asks for a qcn file along with hex editor to input your box IMEIs. All follows up on my end until I use Qfil to restore a changed qcn file. It only writes till 2% and then phone goes into ramdump screen which means there's some kind of IMEI write protection on device or something like that. Because all other IMEI writing methods fail the phone to same RAM Dump screen. Desperate for some help.
Also there seems to be a problem getting diag mode to work on all stock ROMS. The only way diag mode works is by using ENG factory firmware on my ROG 5 which enables diag mode by default. The Asus_volte_su_fixed apk provided by @twistedumbrella Also doesn't enable diag mode on ROG5.

This is not based on my own experience - but it looks like you may have access to write the IMEIs to this device via one of the ASUS Key partitions - in which case you may (or may not) be able to bypass writing QCN altogether.
I forgot the name of the guy who posted it, I believe it was under a CN>WW conversion guide - try to look it up and give it a try...

The Imei part was mentioned in the very last part of thhis guide:
Repair ROG Phone 5 ZS673KS through edl firmware, no need to unlock Bootloader to modify COUNTRY CN to WW
These materials can only be used for ROG Phone 5_ZS673KS, and ROG Phone 5S_ZS676KS cannot be used. ROG Phone 5S ZS676KS Please see...
forum.xda-developers.com
Someone tried that for a seperate reason and apparently it changed their IMEI:

Now, When I change the asuskey4 file, My IMEI do appear in the bootloader screen but when phone starts, it goes into a boot loop which stays even if I reflash the ENG firmware or stock firmware and ending in RAM dump screen.
Erasing the modemst1,modemst2 and fsg partitions from the phone does allow to get out of the bootloop. But shows Null Imei in the phone, while showing the IMEI in the bootloader screen.

So, apparently if I cannot restore the qcn file, There's no other way.
But Restoring QCN in ENG factoey firmware using QFIL or QPST only goes till 2% and then fails and phone goes to RAM Dump screen. Which apparently means that the phone has somekind of NV data write or IMEI write protection.

Writing QCN via Qfil goes till 2% then phone turns off and then status goes this 164% after which it shows that:
2022-05-05 08:53:19.685 Subscription ID:1 EFS File:/sd/mru001_ext_Subscription01, Function:NV_Tool_WriteNVsToMobile, Event:3 164%
2022-05-05 08:53:19.686 Done uploading the QCN file: C:\Users\mhrs_\Downloads\Compressed\GenericIMEI\patched.qcn, Sync EFS
2022-05-05 08:53:19.687 Done EFS Sync
2022-05-05 08:53:20.689 Reset Phone

2022-05-05 08:53:24.208 Finish Restore QCN
Attached is the log file from Qfil.
After this, phones goes into RamDump screen and when I hard reboot the phone, I can see IMEI changed from Null to 0 but still not my original IMEI :/

using qpst to restore only goes till 4% after which phone gets stuck in Ramdump screen.

Hi, Guys. I have the same problem since few days... Hope we will find a solution soon.

You cannot use others's qcn file to restore your imei. The imei store in fsg, modemst1, modemst2 also in your qcn file. If you use others qcn then they don't match each other, you'll failed to restore. The key: you need to empty the partition of fsg, modemst1, modemst2 in oder to restore other qcn file, but the system is read only so you cant do anything.

[LMV600AM] permanently locked (network)

Hello guys! I recently bought LMV600AM(AT&T) from eBay and inserted wrong network unlock code. So the phone said that "this phone is permanently locked..." and network's dead!!!
Anyone knows how to fix it??
I tried lots of things, such as change rom, crossflash to T-mobile firmware.. but nothing solves this problem.
So, here's my questions.
1) Can "Bootloader unlock" process solve this network lock problem?
2) I contact to someone who says that he can solve this problem. He says that he has "engineer firmware(or development firmware)" - I think this is LG developer's stock rom maybe...-. Also, he says that "I will erase every partition, backup partitions by enginner firmware and just rewrite your IMEI, then problem will solve." Is that true? Is there a "engineer firmware" for LMV600AM?? if there, anybody please pass over to me??
3) I follow "https://www.hovatek.com/blog/fixing-this-phone-is-permanently-locked-on-lg-v60/" this solution, so now my phone is currently T-Mobile firmware(v30b) and my S/N is changed to other number. Still, network doesn't work. Fun thing is that when I boot the phone, it says "you have to unlock network by unlocked app". But when I go to mobile network menu and tap 'network unlock', it says "this phone is permanently unlocked and can use any carrier." And still network doesn't work. What's the problem??
