Hi guys,
I have searched and searched and tried every method i can find. I have a phone that was working fine, i used winpwn to get to 2.0.2 and then i had no signal.

I read people had an issue if "activated" was checked - i created a new ipsw without this option, then entered DFU mode and pushed it on

No signal

I downgraded to a stock 1.1.4, i also isntalled itunes 7.5; then used iliberty to unlock and activate, still no signal

I have tried with many different firmware versions, no luck.

I also SSH into it, tried to replace lockdownd, which i read on another post.

When I use bootneuter it has an error, couldnt talk to bootloader...

THE STRANGE THING IS I HAVE TWO IPHONES, BOTH WORKED FINE UNTIL I TRIED TO UPGRADE FIRMWARE, NOW NO SIGNAL

Please help!!!

is this a baseband issue? activation? Please help!! I have two bricks!!

Just to be sure, 2G or 3G iPhone?

What is your current modem (BB) version 04.05.04 ?

Something you could try is downgrading to 1.1.4 but also downgrade the BB to 04.03.13_G with kiphione if you didn't do this last time

Then restore back to 2.1 again afterwards and see if that repairs the BB

I feel for you man. This is from another user that fixed his "no service" issue, can't hurt to give it a try.

how he did it
ok u first need to downgrade ur phone to 1.1.4 with itunes 7.5 after that u need to use winpwn and downdrade it for 2nd time with 1.1.4 firmware to do that u have to press brows.ipsw and look for ur firmware 1.1.4 after that u have to press ipwner and it will do its thing. this is only if ur phone stays in recovery mode if the winpwn does not whant to pwn ur phone u will need to get i liberty and jump out of recovery mode after that ur going to upload ur phone with the new 2.0 firmware cracked with itunes 7.5 its going to do its thing and then ones its done the firm ware will fix the carrier problem and u will be able to make calls

Best of luck
