@ameho: I think NiLuJe meant that if the device was already jailbroken, the oldupdate hack could have a usual name like
Update_oldupdate_install.bin, no
zh.sh would be needed and it would look nicer.
We tend to believe in UNIX philosophy:
do one thing and do it well.
The hacks don't need to re-jailbreak the device, once the door is open. That's the job of jailbreak.
Imagine updating all the hacks with their own jailbreak when the old attack vector is closed and a new one is found.
Yes, this approach requires some level of cooperation and sharing of achievements, but that's no problem here on MobileRead.
See the attachments - that's how it would look like if it was invented here on MobileRead.
Anyway, it's a nice trick, thanks for sharing.
