the only way i see that possible is by running a few terminal commands, but then again, i believe that the .deb has to be installed via iPhone. my suggestion is as chex said, you want to re-jailbreak it. i had this problem a few times in the past and that's really the only way to have a stable jailbreak after something like this. also, why jbme? i used that site a couple of times when first upgrading to IOS4, but since there are a few programs out there that give you a stable jailbreak, why not?okay n00b question here, after un-installing cydia can't we just install it by .deb downloaded from safari ? If not, den why ?
i don't want to assume, but it would depend on how he upgraded. if he upgraded straight from Apple, it could be the jailbreak, meaning it could be that Apple implemented some crash protocol on the jailbreak or the jailbreak itself went bad.You mean to say jbme won't give stable jailbreak ?
