It appears that you have immobricked your ECU. You were supposed to only use the 5G0 frf as an unlock FRF and then use extracted bin from FRF compatible with your 8V0 ECU. For now I think the only option is to construct bench equipment based on br3id documentation. Or find someone with bench equipment to flash your ECU back to stock.

Hello,
I have found someone with a Flex device and I have provided the stock bin file (Size 6144 KB) based on my original ID
Do you think this file will restore the car to stock? because I was told that the coding is missing on my ecu and will require online update to fix
attached is my the screenshot that the technician sent me to show me that the coding is missing
from vw_flash.
The Coding will usually return once the correct software is restored, the issue right now is that when it goes to restore it from DFlash it's failing the parameters check since the incorrect software that's now on the ECU doesn't support the coding from your car.
However, even if the Coding does not return, online access is not required to write a Coding value, you would just need to calculate the correct value for your car (or hopefully you have the one from before) and then it can be written with VCDS, VCP, or even OBD11.

Coding is saved in the logs you provided so it should be as easy as copy and code through VCDS/ODIS/OBDeleven. Regarding Flex bench flashing and the file you provided I have no idea.

So based on this vcds id your ecu still got comms? Did you try to force update it with flex?

Hello,
Its been a few days.
I took the car to a few technicians
They tried to do it online and in a few different solutions nothing is working
they are saying they cannot make any adaptation to the immobilizer
The only way is to make an immo off, when they are doing so the car is starting but the problem is if I try to flash any file by obd (HP tuners or Kess) the car will not start and they will have to do the immo off again
can you help me further?
Is there a way that you can log in by teamviewer and try to make a fix ( I think people here have limited knowledge)
Also I am willing to pay for a correct fix that will restore my car to the conditions it was before

if you have tools to make an boot/write send them to me : [email protected]

Simple immo bypass which works on all ECUs and TCUs, including MDG1:
- Read the ECU in bench mode
- Delete (replace with 00) the whole calibration or ASW sector. One block is enough.
- Load this corrupted image back. Do not do CRC.
ECU during the booting process checks the integrity of ASW+CAL sector. If this check fails, ECU will stay in the bootloader, but immobilizer won't be enabled. You can then flash your desired boxcode.
When you flash correct boxcode, which immobilizer is paired with, then it will release automatically.

- Delete (replace with 00) the whole calibration or ASW sector. One block is enough.
Even one byte is enough, really, since all you're doing is forcing the ECU to stay in CBOOT. This is how I flash ECUs on the bench with my own tools, since the OEM flashing routines are faster than my own bootstrap loader - I erase a single flash region, then reboot into CBOOT and flash over UDS.
The issue I've had with recommending this approach to others with commercial tools is that most of them are crap and end up confused by the idea of flashing such a file - either they force-correct the checksums, refuse to write the zeroed region, or some other nonsense.

You should not need an immo off file, just one with the tunIdx array matching the immobilizer data that is in your car (that is - a matching box code to what came on the car to start with).
Whatever file you're trying to flash over OBD must not have a matching tunIdx to the ImoDat in your car - are you sure it's a correct file matching the original box code? Hopefully trying to adapt the ECU didn't mess something up.
