The best way is simply to save a *.cap file with the PROBES and M messages and to add a *.txt file with the output of modified reaver.
In the case that the chipset and/or the model-manufacturer doesn't appear fully/dirreclty in the probes/stdout of modified reaver, please add manualy this information

They are not corrupted but you need to get m1-m2 and m3 and you will not get this full sequence on a locked router (until it is unlocked again).

Do you know how to "disassemble" firmware? i am stuck and need some help, i found something very interesting on unsupported realteck in parts that can be disassembled easly with binwalk from craig heffner.
basically there is a little *.sh script on startup that generate 4 things ( or check if theses four things have been generated correctly and generate them if that not the case) and one of them is the default WPS PIN.
on this devices the PIN is permanent/unconfigurable
Help would be appreciated
