Yesterday i accidentally updated my iphone to 2.0, my phone is unlocked and jailbroken.
i downgraded back to 1.1.4, because 2.0 isn't unlockable yet.
but now when i try to unlock my iphone it doesn't work, i have no signal bars.
also iNdependance doesn't detect my iphone.
what should i do to get signal back, im not really bothered about the jailbreaking its just, i need my phone to work by tomorrow morning because i have a meeting at 9:00

You need to downgrade your base band too....

KiPhone

Thanks, i'll give it a shot now

when i go to downgrade, it says "entering recovery mode" and then just stays in recovery mode, is this normal?

[mingkit]

not normal.
What version itunes you using.
maybe try to run on another pc with itunes 7.5

It just like run Ziphone.
Go to recovery mode
run command line on iphone screen
iease
write back old version base band

I tried using KiPhone, but my iphone got stuck at the apple logo screen. Now I can't even enter recovery mode and my computer does not detect it. Any ideas?

I'm having the same "No Signal" problems after downgrading from 2.0 to 1.1.4.
I've spent HOURS today trying to fix the problem by trying everything I've been reading on various forums... I've tried using ZiPhone v2.5, winpwn, and iLiberty+... I've tried doing stuff to the bootthingy... I keep getting the 1015 Error... I just can't get any freaking signal... any advice or suggestions?
Thanks, gang

Im glad im not the only one, Im using itunes 7.5, im going to leave my phone plugged in for a while, see how it goes.
If that doesn't work then i'll try a different computer
i'll let you know how i get on

I really can use KiPhone to fix the no signal problem.
my step:
uninstall itunes7.7
install 7.5
duf restore 1.1.4
iLirberty or Ziphone jailbreak and activate

finally kiPhone same with ziphone execute screen (must be itunes 7.5)

I had the exact same problem. Once i got the iphone out of recovery mode and activated it. I then used this modded version of ziphone (http://forums.macrumors.com/showthread.php?p=5771120) to change the modem firmware back to what its supposed to be.
