i did the same thing same problem .. phone is showing slide for emergency calls

still waiting for dev team to come up with quickpwn/pwnage tools

kindly post latest updates on pwnage tools here .. hv to divert all calls to house phone for now

iphone 2G previously on firmware 2.2.1

accidentally upgraded to firmware 3.0
(me & my itchy hands, was told by a phone vendor that apple no longer cares about 2G so firmware upgrading is ok)

phone currently showing "slide for emergency"

however .. to my surprise i can still make/receive calls .. receiving SMS poses no problem too! can't send SMS though as i can't get into springboard

i have been trying (very hard) to downgrade/upgrade my firmware but i was always shown error 20 halfway thru the process!!

Systems Used - PC on itunes 8.2 & Laptop on itunes 8.1.1

Tried the usual drill, enter DFU mode (many many times) press shift & restore ..
tried firmware 2.2.1 & 2.0.2 .. same error .. error 20!! at one time i can't even get to "slide for emergency" (phone shows the connect to itunes screen) but after upgrading to 3.0 no problem

I guess i will have to be patient and wait for DEV team to come up with quickpwn 3.0 (fingers crossed)

anyone .. any solution??

any reply is greatly appreciated

thanking you in advance

sorry my bad .. will try again when i'm home later today

fingers crossed

thx for replying my thread
