Did you exactly follow all the steps from DFU tutorial?

Check voltage and diode mode to ground at all LDO rails of both CD3215 chips.

So, you get correct 1V1 LDO on both ports?

Any history available?
Did you check for liquid sign on the audio board?
Remove it and check its both sides and audio flex.
