dear Sir..

i have iPhone which has a strange behaviour, if it is plug in wall charger, it can turn on but in restore mode (only cable and itunes logo)

but when i unplug it, the iphone becomes dead, plug it into computer usb, nothing happen, cannot detect either.... by itunes

is my battery already dead? or it is still software problems?

someone please give me opinions,....

thank you

its drains out of battery completely
so if i charged under recovery moce, the battery is not charging (i've seen someone says that when updating firmware or if the iphone has corrupt firmware it will not charge battery)

i've make modification with the sync cable, cut off the power supply line from computer usb, attach the Voltage line from the charger

plug in, itunes can recognize it in recovery mode, but when i do recovery process it says "error 5"

ok ...

good news hehehe
i open it up, and found out that one of the line from battery was broken...
now its already in good shape
