i don't have a dongle, and don't know anyone who got one... And by the looks of this, i'm not going to buy a dongle, if there isn't any chance of recovering this...
i was a able to do a good, clean dump (001000) now. Flowrebuilder successfully reversed the .bin. Now i'm going to try to do it like you said. If it works, which one should i use when i solder the cable?
edit
done it. now i have both normal and flash dumps. And good ones. Damn E3, not working the first time, and now working two times in a row...
edit
i found my bad dump from earlier, tried to revert and extract, with errors... then i compared both bad, and good dumps extracted folders, and i've noticed some differences. Should i try to copy paste some files from the good dump, to the bad dump folder, then "zip" it back to a .bin file, and then check again for errors?
