2. in mmcblk0p12/PhoneInfoDisk folder i wroted via HEX Editor my SN, mac adress, bt adress, color of device(5J)
3. Pack back via make_ext4fs.exe tooll to mmcblk0p12
4. Then I flashed this mmcblk0p12 via fastboot flash /dev/block/mmcblk0p12 mmcblk0p12

I was able to get it working with a workaround , I hope it helps u.
Go to /config/telephony/1 directory. Take backup of all files. Delete all files. Reboot phone. Check your imei.

Do you have factory/PhoneInfodisk/PhoneInfo_inf file? If yes, you can recovery Serial number, wi-fi mac,bt mac by editing it with HEX editor, I not sure, you may use even text editor. If no, you should to get this file from other device. Also you should to write your Serial number to factory/PhoneInfodisk/ssn. I suppose you can try to flash this service firmware, this firmware add Virtual Serial COM Port for working Digma sofia recovery tool- thats all.

Firstly thank you,
In short I say,
Mistakenly I erased all the partitions that includes
System,Factory,Config,ADF,ADP using CWM Recovery advance mode .
After that I flashed a stock rom to unbrick the phone from previous bootloops caused by FOTA update on the rooted device. After that my phone booted but no imei and info.
So I think my factory partition is empty as I formated it
And the firmware you provided is for ZE551ML 4Gb Ram variant while mine is ZE550ML 2Gb Ram.
Will flashing this work for my phone or if you can kindly provide me the Digma servicing firmware for my device!
Again thank you

There's no factory/PhoneInfodisk directory showing in root explorar

Don't be afraid, you may flash service firmware from my post via asus flash tool from fastboot mode! This firmware need ONLY for activate Intel virtual COM PORT in device manager on PC, for using Phone Tool 191, no need use phone on this firmware . after repair of your imei1 you should to flash user RAW firmware for ZE550ML -that's all. For repair imei1 no need factory partition, both sim card will be become work, simple you will not have your serial number (it will be 111111) and mac addresses will be not sibling from box of phone, they will be random generated. WI-FI and BT will be work on it too

Perfect this ended up working on my phone (ZE550ML), flash the service file in the link using Asus Flash Tool, connect to Digma, you dont need to intall the drivers. Follow the pdf to change IMEI, use google translate it works good, remember to omit the last number in your IMEI.

Redmi 6A big problem(please read carefully)

Hello everyone,
I have problem with this redmi 6a mtk phone.I need to say that bootloader is locked.
Every time when is booted up it says "this device is locked" with stock roms(not modified).
It is working well but when I connect to wifi or when insert sim card in few second I get that message and I cannot
do anything with phone.
So what I did because I have Mi authorization account for EVERY Xiaomi phones(thanks from an service),I downloaded
modified redmi 6a firmware from:
http://forum.gsmdevelopers.com/xiao.../68692-redmi-6a-cactus-modified-firmware.html
and I flashed it with sp flash tool successfully.
I booted up,but now I have another big problem,I lost imei and device ID,I can connect with wifi and everything but no imei so the device ID but at least thanks from Mod. firmware there is no pop up "this device is locked"anymore .I think that this phone does not have Meta mode because I tried that with Maui Meta to recover imei but without luck.
So I have question is there anything that I can do more with it to recover imei and device ID or is there any other solution to bypass that message "this device is locked".

[GUIDE] Restoring IMEI and EFS after erasing or corrupting (No backup needed)

OOPS!
You were following guides on XDA, and throwing random commands in ADB from the posts under the guides (DON'T DO THIS!) and now your slick new ROG phone 2 doesn't have mobile data, calls, wifi, or bluetooth. You quickly find out that flashing the phone with any firmware old or new, doesn't help you, as this issue is directly linked to your chip in your phone.
I quickly found that I needed a QCN file from someone with a rog 2 phone, however I could not get any help here on XDA except from the user Greatuser123, who did not want to give out his QCN file (understandably), but did send me some notes to try and help with other tools.
With nothing working, and no QCN file, I ordered another ROG 2 and waited for it in the mail. After it got here, I quickly extracted the QCN file, replaced the IMEI's in it, and used QPST to restore my phone.
I am simply writing this guide with the generic QCN file with my info masked out of it, so no one has to go through what I went through.
Common issue
This most commonly happens with ROG 2 Phones from the commands:
DO NOT RUN THESE COMMANDS UNLESS YOU KNOW WHAT YOU ARE DOING!
(spaced command to ensure no one runs this!)
fastboot erase modem st 1
fastboot erase modem st 2
Click to expand...
Click to collapse
On most phones, on a reboot, these partitions would be restored on reboot, but not on most ROG's.
Prerequisites
Rooted Phone
QPST
Qualcomm USB drivers
IMEI Converter
Platform Tools
The Fix
Follow the above root linked video, or find the root thread for your phone here on XDA, and root your phone. This will not work unless you are rooted, although I do not know how you would get into this mess without having your phone rooted already.
Install QPST tools
Install Qualcomm USB drivers
Download the attached zip "good_qcn.zip" and extract the .QCN file anywhere on your machine
Open the .QCN file with any Hex Editor (I used HxD) and search for the Hex-Values: 08 3A 85 99 99 99 99 99 99
NOTE: There will be TWO locations with this value. This is where your IMEI_1 and IMEI_2 will go. Your IMEI_2 goes into the FIRST occurrence, while your IMEI_1 goes in the second.
Download the IMEI Converter app and type in your IMEI_1 and click "Convert", place the converted hex output into a notepad or similar
Do the same for your IMEI_2 and place it in the same location
Now that you have the HEX version of both your IMEI's, paste your IMEI_2 in the FIRST occurrence of the fake IMEI in the QCN file
Paste your IMEI_1 in the last occurrence of the fake IMEI and now save your new .QCN file.
Ensure your device is in USB Debugging Mode.
Download and extract the Platform Tools if you do not have them already.
Plug your phone into your computer using either port
Navigate to your extracted Platform Tools and in a Command Line type "adb devices" to ensure your device is visible.
Run a shell with "adb shell" and elevate your permission with "su"
Now it is time to enable Diag mode by running "setprop sys.usb.config rndis,diag,adb"
At this time, if you installed the Qualcomm Drivers, your device manager should have a port similar to "Qualcomm HS-USB Diag". If not keeping trying to re-enter diag mode and ensure the drivers are correct.
Open up "QPST Configuration" which was installed earlier. You should see your phone listed under "Active Phones". Click "Start Clients" -> "Software Download"
The Port field of the QPST Software Download should list your phone, if not something is wrong.
Click "Restore", and in the xQCN field, click "Browse", change the file type from XQCN to QCN, and select your newly made QCN file
Click "Start", and once the process is done, restart your phone
Conclusion
If all went well, your phone should now have all its bells and whistles again. Sometimes it may require a Factory Reset, and this should always be the practice anyways. If you have mobile data, but only H+ or EDGE, dial *#*#4636#*#* on your phone and ensure LTE is provisioned.
Good luck guys!

Hi bro, Nice to meet you and I did my best to help you out, as I spent some stress on this when I was one of the first people that suffered with this issue. And gladly you solved it, bro you misunderstood badly about I did not want to give you the qcn, I was going to give you my qcn file but first I was asking to you for some proof , photo of same phone as me and the package to know that you are not going to change or edit badly ( doing mischievousness) as you never sent the proof I did not send the qcn file.. you can re check again your messages. Bro

Thank you very much for this, life saver.
My wifi and bluetooth works fine but I cannot get my mobile to power back on. When I go into the menu mobile power is just not there :/
Do you have the global or the cn version?

This QCN came from a global device, but I imagine this could be used to recover the mobile at least temporary to fully fix the device, no matter the origins.
Sorry for the delay.

No no, please do not think I meant you by that. It was other users (understandably) that questioned my motives before you. I absolutely would have taken you up on your offer if I did not already have the phone on the way Either way, I really appreciate your help during this, and I hope you continue to help other users the same way you did for me.

After a lot of heart ache and even making an EDL cable I could not get cell network back. I"ve sent it into ASUS to get fixed. I have made a few backups and will diff them when I get my device back so hopefully I can see what they have fixed so others don't have to experience this.

Qualcomm Diagnostic Mode code

To enter Diagnostic Mode dial:
Code:
*#*#25327337#*#*
In QPST phone is identified as "KOMORTA_H (0)" (I don't know what that means).
But I was able to do *.qcn and *.xqcn backup with correct IMEI numbers inside those files.

According to https://github.com/MiCode/Xiaomi_Kernel_OpenSource, kernel source for Redmi Note 9 4G/POCO M3 has a base tag of LA.UM.8.15.r1-06600-KAMORTA.0. This info might be related to what you have found.

Does this mean that qualcomm EDL mode works freely and that possible hard bricks can be fixed by the user himself or as other Xiaomi devices there is a need for authorization (which is never granted to the user)?

I don't think so. I only tested making a backup. I didn't try to write anything on the phone and I STRONGLY advise against that.
Ps: I'm new to Qualcomm ecosystem so take what I write with caution.

Repair IMEI - Diag mode

While trying to install a Custom ROM, all went wrong with a hard bricked Redmi Note 8T as result.
Have been able to revive the phone in EDL mode (Test Points method). Now running again on MIUI Global 12.5.5 (RCXEUXM).
However, the IMEI's are nulled, can't activate a SIM card. Only WiFi works.
A first, essential step in the process to repair the IMEI's, is to open the diag mode. Found a few methods, but none of these methods work.
Not via *#*#717717#*#* (Open diag failed), not via adb devices // adb shell // su // setprop sys.usb.config diag,adb (Permission denied).
The phone is rooted with Magisk; recovery OrangeFox.
Does anyone have a helpful suggestion how to proceed?
Follow-on: Meanwhile, I've been able to open the Diag-mode. Apparently, one or two switches in Magisk had masked the rooting of the phone.
Now on to editing the qcn-file with the correct IMEI's. First,I have to figure out the location of the two IMEI's, and then to correct these into the correct values.
To be continued...

I have had the same problem with my previous Redmi Note 3. And I tried so may ways to re-write the IMEI number. Finally I found a little software on the net and using my computer I was able to re-write the IMEI number to the phone. I was a long time back, so I dont remember the exact name of the software. It was something like IMEI writer (root). Connected the phone which was also rooted. Then opened the software on my PC and the software asked for superuser access, which I granted on the phone. Then there from the pc using the software I entered the IMEI numbers for both sim1 & 2, and applied then reboot phone. After reboot, the phone then detected the simcards and the imei were back.

It was something like IMEI writer (root). Connected the phone which was also rooted. Then opened the software on my PC and the software asked for superuser access, which I granted on the phone. Then there from the pc using the software I entered the IMEI numbers for both sim1 & 2, and applied then reboot phone. After reboot, the phone then detected the simcards and the imei were back.

My current problem: I can find a .qcn file and have to edit it with the proper IMEI's. Found a Qualcomm IMEI Rebuilder tool, but that tool doesn't work. With a Hex-editor it is difficult to find the proper location. Found the location of one IMEI and then saved the file with a different name. Loading that file into the Rebuilder tool indeed shows (one) correct IMEI. Have installed that file with QFIL, but when I check with *#06#, it shows a completely different IMEI...
Meanwhile, I've searched for IMEI write (root). Found IMEI Tools (ROOT)_1.4_apkcombo.com.apk.
Prooved incompatible for my phone.
Then found qualcomm-smartphone-write-imei-tool-v1.01.apk
Tried that out, but couldn't establish communication with the diag-COMport.
In fact, I can't activate the diag mode any longer... Tried and re-tried, but all in vain.
When I enter the last command ('setprop .... etc.), communication via the USB port is also stopped. Re-establishing that doesn't make a difference. No COMport appearing in device manager or in QFIL...

You need special tools like UMT or Hydra to write Note 8 imei

UMT works with dongle? Price?
I tried Hydra, but got a Trojan Horse warning, and therefore broke off installation.

Umt needs dongle.

First restore original qcn(unedited) then try flashing ENG firmware.
