Had an iasue with my bmw... Tryed to write a file but flash failed and now get wake up error and no ID... So had the ecu read by bdm and wrote the full read from obd flashed onto the ecu... But still not getting ID or vehicle starting any ideas??

If you got BDM Backup use BDM to write.
BDM often read more sections than obd... so not advised to read via bdm and write obd...

i need a full read with matching HW and SW but we cannot find one anywere

So push hw, sw number and sw-version... but at the end of the day you also have to sync ews...
