DME / EWS Sync is not working.

[HoDoo]

Hello,
I replaced the DME of my 2003 E46 M3.

I completely initialized the DME using the virginize function of mssflasher and flashed it with the desired full bin file. I even perfectly inputted the VIN information.

However, I got stuck at the last step, which is syncing with EWS.

When I use the sync function in INPA, it shows Error_SG_Rejected.

When I try the method in tool32, it shows "okay," but it still doesn't seem to be synced.

I followed the instructions in the last post of the thread below for the sync method in tool32:

I really want to resolve this issue.

I verified that the 'Tool32's sync command between DME and EWS works correctly through the original DME.

So, I suspect the issue lies with the 'used DME' I'm trying to install not being properly virginized via 'MSSFlasher'.

Upon rechecking the logs, it seems that there's a timeout occurring during the virginization process, preventing it from completing successfully.

1. Has anyone successfully virginized a 'used DME' via MSSFlasher and then succeeded in EWS sync?

2. Is ROM flashing for virginization only possible through full memory access flashing via BDM?
-> Is it possible to resolve this through binary modification?

I'm eagerly awaiting help.
Please, if you know anything, help me out.
