hi to all! i've tryed all tricks of this world but nothing had work....iphone 2g 8gb upgraded to firmware 2.2 with quickpwn: NO SERVICE. please help me to undestrand how to fix it! i've seen different trick like this:

1a.) uninstall iTunes version higher that 7.5
b.) delete the "iTunes Library.itl" file located in C:\Documents and Settings\"username"\My Documents\My Music\iTunes
c.) download and install iTunes 7.5 - if u do not do the sub-step above, iTunes will not start.

NOTE: i think the step above is what caused my headaches, but since i'm not a programer i'm not sure.

2a.) using iDemocracy erase baseband and then place into DFU mode(from the things i've read, i do not trust Ziphone)
b.) restore to 1.0.2
c.) repeat step 2a - restore to 1.1.1
d.) repeat step 2a - restore to 1.1.2
e.) repeat step 2a - restore to 1.1.3
f.) repeat step 2a - restore to 1.1.4
** u do NOT have to jailbreak or activate in between any of these sub-steps above.

** NOTE all of those sub-step of 2 might not be necessary but i did it out of paranoia. u might be able to just jump from 1.1.1 to 1.1.4.

3a.) using pwnage tool to jailbreak your iphone - in your advance tab of the pwnage tool:
- check "enable baseband update" box
- check "update bootloader" box
- check "upgrade to 4.6" box
- make sure to the "autodelete bootneuter.app" box is NOT checked

** finish all the required steps for the pawnage tool

4.) using the bootneuter app in your iphone, downgrade bootloader to 3.9, neuter and unlock.

but when i try to restore with the custom firmware itune gave me error 1601

or this

I had that same problem....i finally got it....it was easy in the end...>GUESS what i did...

i'll put it here you should understand my procedure if u've been dealing with iphone for a while...

i had that No Service problem, no matter what firmware i put the 2g iphone in...was frustrating me...

finally i uninstalled my 8.XX itunes and installed iTunes 7.5

Then i downgraded to 1.1.4
i got error
1015 or 1013, that is normal
i used ibrick to boot normal, if screen shows Green just restore again to 1.1.4, try ibrick again and screen will show red and phone boot normal
Then i used iLiberty and unlock, activate, downgrade to 3.9, youtube activate and installer...
Then run and iliberty will jailbreak iphone...still it will not work...
Now: open " _En__ZiPhone_patched_by_kIREmK_04.05.04_G"
Listen carefully, if you downgrade baseband and did Debug Mode already, all you have to do now is

JUST CHECK MARK DEBUG MODE & iErase, and press START,

after that my phone rebooted and it worked well....

i spend all hours trying all kinds of stuffs and the trick in the end was to do an iErase....

Cheers, i've tested it and it's 100% bring back my signal...and no more call failed or call back...

Enjoy!

but when done, i can'use telephone (STRAGE RED DOT ON TELEPHONE ICON) and wifi!!!
