Default Help with flashing gearbox ecu needed

Hello guys, I have a question regarding a gearbox flashing on my Audi A4 B8 2.0 TDI 130kw Multitronic (year: 2012 EU, model year: 2013 EU). I have an original VCP interface and software.
I had no problem "downgrading" my engine ecu with original pre-diesel-gate map, however, when I tried to flash Gearbox ECU, flashing stopped with error right at the beginning, writing data to first block.
I have tried this several times, but it is always the same.

I can still access the ECU, however coding is gone and I can not access advanced ECU info. There are no DTCs in gearbox ECU, but there are some on other modules stating they can not communicate with gearbox ecu. I have not tried to start the engine since this occured as the gearbox almost definitely won't work and I do not want to cause any mechanical damage.

This is the software part nr: 8K2927155L
My previous version was: 0005
I tried to flash it with version: 0007 (original Audi file: FL_8K2927155L_)because there was a TPI with some improvements.

I have attached a scan before and after flashing and flashing log.

Can someone help me? Is there a way to somehow flash this new version or at least get back to a previous one without visiting the dealer?
Your help would be much appreciated.

Thank you.
Rok

I have successfully flashed TCU today.
I did two things, I do not know which one actually helped.

- changed flash block size from maximum to default
- i noticed that car battery voltage dropped below 12v when ignition was on, looks like the charger did not properly work or something, so I hooked the charger up directly on car battery in my trunk and waited so that the voltage with ignition would be more than 12v. I then retried flashing and it went smoothly.
