you are the Best !! +rep for ya
The SB low (tristate with GND) worked fine for me. Now i have finally the bootloader of the new 2004B slim. Let's se if writting works, i let you know. Oh and i used the newesd WinSkeet with WinUSB on Win7 64 bit.
When i have downgraded the con and finally can work again i will write a guid for all other users. It's a shame that the Team is not able to provide one single useful guide.
ps. forgot to say that i have soldered the wire from gnd to tristate on the progskeet pcb not on the mainboard
Also writing worked without any error
Have made a dump after successfull write and got the same checksum as the downgrade.bin have. 100% correct flash.
Used Win7 64 Bit WinSkeet 40000_111004 with libUSB0.
