Have similiar problem with an E90 last month. You have no communication with DDE because flash its corrupt. When you work on BMW cars make sure that you have 13V+ power.
Only way to alive the ECU its BDM. Write this file atached:267667 and will work.
Then resync DDE7-CAS. I used AVDI for this and ICOM, but INPA cable also work. On INPA for E90 dont list DDE7, use DDE5
engine - dde5 - CAS - reset - store - back - back- remove cable and start engine.

Good luck!
