iPhone 2G can't boot up
I need help. Currently using an iPhone 2G(US version) with Firmware 3.1
The phone is unlock and jailbreak sucessfully without any problem using PwnageTool (using hackthatphone[dot]com guide)
Today, when i open the cydia application and foudn that there is a mobile subtract package update(v0.94 if i am not mistaken). After installed and restart, the phone can't pass through the "pineapple" logo and it will switch off after 10 sec. i have tried to boot several times but still no luck. Press Home and sleep button for 10s also doesnt work for me,
i plug the phone to itunes but it shows nothing.
So what should i do? please help
