I have 2 audi s4s, both are in not running status, right now i honestly cant afford much more, i fried an ecu about a month ago by hitting the battery feed while it was plugged in to the harness, so i looked and looked and looked and didnt find a replacement. so i said screw it and bought another car. well apparently ABT likes to solder in a new board and put a lock so you cant upload or download tunes, so of course i figured id just remove the board and resolder the chip back to the ecu as it was originally, well now i cant connect to it. boot mode or not. I know im new, there is really no reason to be rude or just pass this by without any help. Ive already asked twice which is why i bought another damn s4, i love these cars, and i need to knwo what ecus i can replace them with because any ME7 8D0 is hard as hell to find. All i need to know is if i buy a ME7.1 4B0 type ecu if i can make it work, or how do i go about making an automatic ME7.1 8D0 work on my 6 spd. I have two completely different setups in each car, both are 2001.5 S4s and i think i might actually lose my mind if i dont get them back on the road soon. Ive litterally been sitting infront of this computer and ecu for about 4 hrs straight now, not winning... Any information would be useful.
I guess you are from Europe since you mention ABT. There are several S4 B5 ECUs on e-bay:

Just get one, have someone to solder the immo chip to the new one, or disable it and you are good to go.
