i read faq, , after searching forums found similar issues nothing quite i'm dealing with, hope posted in correct place.

problem:
iphone 4 won't turn on unless plugged in. when plugged computer apple logo comes on 30s phone shuts off 10s, comes on , off again on , over. when plugged wall outlet attempts boot jailbreak , loads emergency call screen connect itunes logo in background (shows full battery), before reboot cycling.

details:
original iphone 4 bought first week launched 2 summers ago. past year or i've been running jailbroken version of ios 4.3.5 installed greenpoison. never felt need update because had phone functioning way liked it.

while driving, phone sitting in xm skydock pandora playing (because cancelled xm subscription liked , kept dock). hit small bump in road , phone shut off , responds outlined above.

put phone in dfu mode , attempted restore device. itunes got verifying restore apple , timed out error 1600, or 1602 or 1604 never complete. ran tinyumbrella , tried restore 4.3.3 tss server running, process errors 2005.

tried 'fix recovery' button in tu , attempted turn on phone while still plugged in. nothing happened closed tu , phone screen came on white second before coming basic greenpoison load screen. load screen white text , said greenpoison @ top followed by:

unable find gbdevlist
unable find fs_mount
unable find fs_unmount
unable find fs_load_file
greenpoison initialized

hangs there second before flashing boot screen bunch of text flies before reboots apple logo , starts reboot cycle on again.

i'm @ loss on how continue , use advice. ever encounter similar issue , find resolution it? want phone work again , prepared lose information on it.

 

error 2005 implies hardware problems, if on windows try reinstalling usb drivers.

have shsh's 4.3.3?
make sure hist file set cydia in tu

try again in dfu mode keep tu off.
use alt-restore (mac) or shift-restore in itunes restore 4.3.3 ipsw.

can restore stock 5.1.1 if don't need unlock, thats do, more features on 5.1.1
