@T5-T6-Schnappi Thanks for advice, i borrowed other cable and everything worked out. Also it works with different part/hardware numbers too( added picture). If it will be useful to anyone, it is enough to buy ETM by model year, the codes may differ.

@T5-T6-Schnappi Thanks for explaining programming mode I already thought something was wrong again .

My internet might be not the fastest, but I am sure connection is stable.

I use not so powerfull charger as yours( mine "OSRAM" provides 8Amps), but I checked voltage during software reading and it was stable 12,7V. Vdash states it needs to be at least 12,6V so I guess Im still good with it.

Adapter I use is from china some DICE clone i got for 50Eur. Name in Vdash is "SM2 USB". Tried to download drivers from Vdash site, but then device is not recognised. So I used chinese seller's provided Scanmatic drivers.

As I understand it, the problem is most likely with the adapter, I think I need to buy a super j2534 from vdash. Is it possible that they will refund the credits for this failed operation if I used the SM2 adapter?

@T5-T6-Schnappi Hi just tried to clone ETM on my s80 2001. Did everything as you have writen. When I put key on position 2 ant started cloning looks like ignition dissapeared - all lights in speedometer turned off, no reaction from windows, radio, clima etc. It seems that the cloning was still going on because the percentages were slowly increasing, but after an hour it threw an error that the copying failed. After that I tried to start the engine and there was still no ignition just ''check engine'' light apeared, crank, but not start. After disconnecting the battery and waiting for a while, the ignition came back and started, but of course the cloning itself failed. What could be the cause of it? Any thougts or tips?
