i got a ipod touch 2g 4.1 that can't be jailbroken... again.
and yes, i know it is stupid that i did put a stock ipsw into the ipod
the reason i did it was because it did start rebooting all the time! i got rely mad and did think that i could yust put in a jailbreaked ipsw after i did put in the stock...
ok lets eliminate what will definitely not work.
Limera1n doesnt work on ipod touch 2G so dont even bother trying it.
The others "should" work. When trying sn0wbreeze have you tried putting the ipod touch into dfu using iReb first and then restore to the custom firmware?
Also depending on what model ipod touch 2G you have, you can try redsn0w 0.9.6b1 or b2 (will need b2 if it is a MC model).
