Hi You have made a big mistake by using KingRoot to root your device.
now you have got some serious issues but they can be solved.
First You need to make full wipe of your device currently and need to flash stock firmware.
1.Back up all your important data.
2.wipe current os by formatting.
3.Install the stock ROM version which you got initially.
4.you will get your IMEI number back.
if you are not clear about above or if the above proceess doesnt help help I will suggest another method.

First go to this link (https://forum.xda-developers.com/honor-4c/how-to/huawei-honor-4c-index-troubleshooting-t3293110) and install ADB / Fastboot and Necessary Drivers and unlock your bootloader(your warranty is void) and check whether your phones being detected by ADB Fastboot
After unlocking I will suggest you next step as per the result you get.
Hi bud .
I hope i can help u with this.kindly follow the instructions properly and u are good to go.
1) install proper usb drivers.
2) open command prompt
3)enable fastboot mode in ur device and connect it pc
4)type this command there.
If u are using mfastboot , then type
mfastboot.exe devices
If u are using fastboot
type
fastboot.devices
5) here ur device will be showed with some numbers. So now put twrp or any other recovery in fastboot folder or the location where u are accessing the fastboot from. Be sure u re named recovery to recovery.img
6)type these command after copying ur twrp to that folder
mfastboot.exe flash recovery recovery.img
mfastboot.exe boot recovery.img
7) Now ur phone will automatically boot to recovery , here u can wipe data.
The bootloop is just because the data partition is still unwiped and no rom will boot . Just format data after booting the recovery .
Thank me if i helped you

Firstly go to this link and download the stock ROM for your device.(the version previous than your current rom)
http://www.carbontesla.com/firmware...-ota-collection/huawei-honor-4c-firmware-ota/
Extract the zip and later extract update.app by using this tool
https://forum.xda-developers.com/showthread.php?t=2433454
Now copy all the files namely recover.img,boot.img,system.img,cust.img into adb folder.
Now go to this link and unlock your bootloader
https://forum.xda-developers.com/honor-4c/how-to/huawei-honor-4c-index-troubleshooting-t3293110
After unlocking now do the following procedure.
1.Enable developer's options in your device.
2.move to adb folder and right click and click on open command prompt here.
3.Now type this command "adb devices" -Displays some id of your device which makes sure your device is connected.(accept prompt on device)
4.type this command " ADB reboot bootloader " or manually boot into fastboot by shutting down your phone and restart by pressing Power+ vol+ buttons.
5.Now you are in fastboot menu.If not try again.
6.now type the following commands
7. "adb devices" -Displays some id of your device which makes sure your device is connected.
8. "fastboot flash recovery recovery.img" - Flashes stock recovery
9. "fastboot flash system system.img" - Replaces your custom rom with stock rom
10. "fastboot flash boot boot.img" - Flashes boot partition which is need to boot stock rom.
11. "fastboot flash cust cust.img"
Now wait for some time and your device will boot into system and your IMEI number is back.
Note:If in steps 8-11 if you can't get success use mfastboot instead of fastboot.

It seems Huawei has messed up with their website even though we enter correct details it is showing error.

thankss
Shared on telegram, thanks!
I'm not using qcn
not edl mode using
1. Flashing 7.8.23
2. 7.8.23 root ( patched_boot.img flashin using fastboot mode )
3. Usb diag mode on (dialler open trying or adb using su diag mode open )
4. Dualwriteimei using and restart phone aaaand booom imei restore (dualwriteimei is youtube searching only small size program and very very best )
5.Phone fastboot mode on and 8.1.10 rom flashing and booom
New telegram link:
https://t.me/joinchat/G1MMfkc6EbEZL-62Ii5YmA
thats not permanen, at last for me, maybe work on 7.8.23, but after update via ota or fastboot, after reboot or reset factory on setting imei unknow again
my solution right now, using custom rom, with august security and push modem file from latest stock rom for update baseband
It works, but if you want to update whole system, you have to backup partitions modemst1, modemst2 or EFS in TWRP, after you backup that, flash the new oreo firmware without data, if dont starts, recover the EFS and try again, if dont, do factory reset and if you haven't IMEI yet, restore de EFS, the problem here is, if you restart your EFS would be corrupted, so you have to restore the EFS and force update to the lastest update with EFS already installed, if youre lucky your EFS never be corrupted again
In my case everything is working fine
No issue upon updating or restoring
than so much raj bro 100% working method
I followed this procedure some time ago and haven't had issues. However today I flashed a new Oreo image and suddenly my IMEI was 0 again.
I restored my EFS partition using TWRP and now everything is fine again, except that my smallband version is back to 953_GEN_PACK-1.... which I think is the version that shipped with tissot_images_7.8.23_7.1. I wonder if it's a problem to run with an older smallband version?
Someone there who can help me fixing my IMEI? I have pushed the "flash_factory.bat"-button...
Mi A1 is working and rooted, no 30sec boot loop anymore, but QPST recognize my mobile just for secondes.
I'm holding my IMEIs in hand but unable to get them into QCN sinced days.
i was Restored persist.img via twrp terminal but my phone still restaring continously

Im sooo stupid kiddo :crying::crying::crying:
Bro my telegram @Byramklc add me
Sent from my Mi A1 using XDA Labs
While I did finally manage to restore my IMEI, I found your "guide" really confusing.
You should without a doubt write it better, so people might understand it better as well.
I've been doing custom Android stuff for around 10 years. While I have never developed anything, I have gotten as far as to the point to where I have had to edit files and input hex.
You should _really_ mention when and how you use the files you provided.
You should also provide the "how-to" on editing the files.
I finally got it to work, but I had to read three different guides before I got it.
Still.. Thanks
Can someone confirm that PSN and FSN will missing if using flash_factory ?? (FSN&PSN can be found on *#*#6484#*#* Version Information)
hello guys ,thanks for the guide, i've restored my imei but the mobile data network still wont work, what it can be?
EDIT: I've resolved by using a newer version of qpst software, the 2.7.472.4 one
I managed to get IMEI back wifi and bluetooth working but sim network lost.
Sent the mobile to service center and they changed the motherboard.
Is this the only solution.......
---------- Post added at 06:28 AM ---------- Previous post was at 06:26 AM ----------
were you able to restore sim network as well???????
If yes pls write a complete guide with all the tools and files used

OP 6 stuck with no IMEI/MEID/BASEBAND/MAC address

Hi,
My OP6 is stuck and keeps restarting. I have flashed all stock roms via MSMtool from hydrogen OS to Oxygen OS 10.3.5. Even tried fastboot rom flashing with no luck.
Flashed stock OS via twrp still nothing.
I do have a backup of my EFS partition but flashing that via fastboot/terminal makes no difference in any stock OS.
I have searched every topic related to this particular error but didn't find any fix yet so was forced to create a new thread.
Need urgent help, it has been 3 months now and nothing worked. Few times my phone did boot properly with IMEI and other details but after few days same error( Don't remember what I did which fixed earlier)
Also, I did visit the repair shop but they didn't find any motherboard or IC damage whatsoever.
Experts/Mods need your help.

If you've efs backup which is uncorrupted, modemst1 & modemst2, flash modem files via fastboot, flash twrp image, flash twrp zip installer, reboot to recovery, wipe all partitions & flash OOS and simply reboot after flash, if your efs backup is not corrupted already, it should boot up fine
Unfortunately it didn't work for me. Now when I'm flashing oos 9 and above, 10.3.5 via MSMtool from unbrick thread..the OEM unlocking is greyed and can't unlock bootloader.
I hope I find a solution as nothing is working, how to verify if the EFS backup I have is not corrupted? Also, I do have a QCN file for IMEI backup will that be of any use?
Have you tried 5.1.5 oos? Even if it is an old android version, it should save your device and as far as I know it does not change anything if the bootloader is off.
Yes I tried, Oneplus_6_A6000_international_Oxygen_OS5.1.5_22_O.09_180517(MSMTool) still no imei/meid/mac address and frequent restarts.
Is there a fix for restoring EFS partition if the backup is corrupt?
Msmtool won't fix it? Flashing persist is also of no use
Guys any fix for EFS PARTITION? If it's corrupted

Your bootloader is locked????
Try to unlock it using command "fastboot oem unlock" , without commas in fastboot mode
See if it unlocks it?

I used msmtool as asked. So bootloader was locked. Since I'm not able to boot in OS due to crashdump error not able to enable OEM unlocking.

No working.
in the official rom ,modem meta can write imei in meta mode (that’s illusion), but reboot, new imei is working.
In the engineering rom, Same as above. It seems eng. rom for poco f3 gt is different from other Old phone, because other phone can write imei in the eng. rom,
But fastboot can erase nvram, then imei is a string of zeros,now imei can be changed successful,only imei slot 1

So I think the official nvram and nvdata is protected ,Both official and Engineering rom,when I erase nvram and nvdata , I changed imei slot 1 successfully ,you can search YouTube ,There is only one video, he deleted nvram file,imei changed successfully

All in one, you can't make any changes to the original nvram and nvdata file, the file is protected, when you erase that, the system generates a new file that is cleared of zero, You can only modify the new file ,and the new file is unable to pass official rom boot detection

Question Invalid IMEI Samsung Galaxy A325G (SM-A326B)

Hello, so the was a magisk update some time ago, I decided to do it this friday (a week ago) (from v23 to v24.1). My phone went into a boot loop so I decided to just flash stock and reflash 24.1, I tried for a few hours, but 24.1 didn't work and I always had a boot loop, so I got back the 23 and thought that's the end. Sadly my IMEI became invalid in the process. I'm not sure what is needed to fix this, or what info would be needed, so please tell me in the comments or something. I don't have any backups of EFS.
I've same problem. Also looking for way to bring my device back to life
Hmm I didnt get this. IMEI not showing in system properties?
*Wait you didnt have backups? Live and learn my friends.
(I keep one that is 15gb on my measely 64gb card in my phone, and a base backup copy on my desktop.)
Nope IMEI is not showing in properties.
Yep I know, no backup is my fault, totally my fault.
My phone even tells me I can't use the *#06# code because it's not supported on show imei, I didn't even know you could break your IMEI. Is there any way of writing the IMEI or something or is it just done?

*#06# doesn't work for me nether.
Altho I was aware of possibiity of breaking IMEI, I was in rush which led to wiping/overwriting efs partition I think
Hello. I have the same problem with the Imei number on this phone. * # 06 # does not work. Displays info that Imei is not supported on this model.

Well so we are in that together, I found something about fixing the IMEI with combination firmware, but it didn't work for me... "Please get the approval to use factory binary : param". Maybe you can try it. Tell me if it works for you
Guys, are your phones also a32's? If so can you check on a rooted phone if /data/nvram Is here? I'm pretty sure that's something important and it's missing for me.

Rooted. I made the warning thread so survived it. No data/nvram present on phone.
i have the same problem i have efs folder but how to restore?
Try
dd if=/dev/zero of=/dev/block/bootdevice/by-name/modemst1
dd if=/dev/zero of=/dev/block/bootdevice/by-name/modemst2
In TWRP console maybe?
I'm having the same problem with an a32 4g so I'm lurking.

doesn't that mean to completely erase those two modem partitions? Won't it finish destroying the phone capabilities?
Hi,
Same problem here after flashing my SM-A326B (A32 5G) with boot.img patched with magisk 23.0 (tried to use v24.1 but phone enters bootloop): it lose the IMEI at the instant I tried to call someone (it was working for a few days, until I tried to call. Receiving a call was no pb.).
I do have a BACKUP of EFS and SEC_EFS partitions made with the "Partitions Backup" app (by Wanam) just after rooting (because you need root to make backup of those partitions). I restored them, which restored IMEI #2 (not the first one) for a few minutes before being empty again (I think it was when I activated WiFi). SIM card was not in the slot. Now restoring the partitions does not change anything. IMEI always empty.
Maybe I should try to flash the original unpatched image and restore the EFS partitions to get the IMEI back (hopefully), then root again using TWRP this time...? The thing is I already have data and apps on the phone and I am tired of reinstalling everything.
I hope description of my pb helps to solve this bug...

Ya, but when you reboot it might reset efs after they are wiped. Seen this in the past. Phones are already missing \efs completely with no backup.

this isn't for Mediatek based phones as far as I know, only for Qualcomm Snapdragon.
Even with a backup of EFS/SEC_EFS, it seems that it doesn't help much to recover the IMEI numbers...
I flashed the original firmware, installed TWRP plus magisk 23 from TWRP, then flashed the .img of EFS and SEC_EFS with adb using following commands:
adb shell
su # root
dd if=/dev/zero of=/dev/block/sdc2 # wipe EFS partition
dd if=/dev/zero of=/dev/block/sdc3 # wipe SEC_EFS partition
dd if=/mnt/sdcard/efs.img of=/dev/block/sdc2 # restore img of EFS before loosing IMEI
dd if=/mnt/sdcard/sec_efs.img of=/dev/block/sdc3 # idem for SEC_EFS
(phone automatically reboots between dd commands). Then I entered TWRP and wiped cache/davlik/data.
IMEI is still empty.
I reinstalled again the original firmware with ODIN (no root, no twrp), hoping that the restored EFS partition would do it with the untouched firwmare => IMEI still empty.
All in all, it seems that a backup of EFS/SEC_EFS doesn't help. Maybe these partitions are not damaged by magisk after all?
Comparing content of the img files before/after loosing IMEI I can spot a few differences in the files, I can detail if someone is interested...

No, EFS is not reset after wiping with:
adb shell
su
dd if=/dev/zero of=/dev/block/sdc2 # wipe EFS partition
dd if=/dev/zero of=/dev/block/sdc3 # wipe SEC_EFS partition
For those who succeeded in rooting the A32 5G without this IMEI issue, could you detail the procedure? With version of the tools etc?
BTW, how come that even just unlocking the bootloader can erase the IMEI? see : https://forum.xda-developers.com/t/sim-not-working-on-a326br.4398149/
