(VW) Seat Leon 1.6 TDI mk2 1p (2012) ECU Flash update issues

[968p58]

RHD (UK) LEON 2012 1p / mk2
Recently updated the ECU using VCP.
03L 906 023 LG 9624 to -> 9968.

Got the file from online somewhere and now I'm running into issues with several control units. The remote center locking is not working, heater / fan is not working, windows have stopped working, parking sensors etc which were all fine before flashing the update using Vag Can Pro. I'll post the scans of the modules below from VCDS and can post the auto scan from VCP as well. The main thing it indicates to is no communication to some of the modules mainly BCM don't know if these need recoding. There was no way of backing up my old flash file frf before I flashed the new file which I can upload here if anyone wants to check it.

Any solutions anyone can provide would be appreciated. Also would flashing back down to 9624 help the issue? I got the file online so not sure if its for like another variant of the vag group like vw golf.
