iphone 3g 4.2.1 bb 6.15.0 stuck in restore mode

[fish ballz]

I've been working on unlocking iphone 3g without ability to connect to wifi or network

I successfully upgraded the baseband to 6.15.00 using pwnage tool

I was trying to use cyder (on windows) to upload packages for ultrasn0w and had to restart phone but now it is stuck in restore

I tried to restore using custom firmware but repeatedly get various messages from itunes that the phone can not be restored (1603, 1604, 1611, 20000, etc.)

I tried to use tinyumbrella but realized that i dont have any shsh previously saved

what to do???

You can't load 4.2.1 (or any 4.x except 4.1) without SHSH.

With no SHSH available the choices are few.
1) Any 3.x iOS
2) The latest 4.3.5
3) iOS 4.1 Apple is approving 4.1 at the moment

Thanks Mes,

Will I have to then download the 4.1 ipsw, pwnage that, and attempt restore again with iTunes?

Are you sure no SHSH is available? Use Tiny Umbrella to check.

If yes, a custom 4.1 firmware built by Pwnage or Snowbreeze is needed. Enter pwnd-DFU w/same. Restore shift/click restore select cfw with iTunes. ITunes Error 1015/6 is ok, use TinyUmbrella 'exit recovery'

Did what you said… IT WORKED!!!

But now there is no signal

Congratulations. Install Ultrasnow with Cydia for the unlock.

It was a 3G mes

The OP was on 4.2.1 and showed no interest in 3.1.3.
When it gets sluggish enough ... he'll be back

[fish ballz]

3.1.3 better than 4.1?

Will it fix the signal issue? I don't think it is the hardware because I changed the dock connector/antenna assembly and still have the same issue

Are you still having signal issues? Sorry, I though it was fixed by installing Ultrasn0w

Bring me up to date. What iOS currently installed? Working? What does the signal bar look like? Does it work sometimes? Etc...

firmware 4.1 with 6.15.00bb

when i put the sim card in, it is only one bar without any defined carrier then after about a minute, it says no service and that remains. Trying to make a call with either one bar or no signal gets a call failed.

[Mes]

Did you install ultrasn0w? Did you reboot at least twice? Settings / General / Network / Reset network settings?
What carrier are you using? Sometimes it takes several minutes to find and set-up a new carrier.

[fish ballz]

ultrasn0w was installed after rebooting at least twice. Using ATT. 3g is off. After >30 min, no change in service signal.

[Mes]

Everything looks ok for the last option. I want you to re-install the iPad 6.15 BB.
It's very simple. No restore is needed and it doesn't change anything on your phone.

Connect the phone.
Download redsn0w_win_0.9.6rc8, unzip, and run it.
Select stock 4.1 firmware ipsw + one (1) option: Install iPad BB.
Follow the instructions to put into pwnd-DFU mode.
When it's finished ... phone will reboot normally. You might want to do it again.

Allow at least 30 minutes to find the network.
If it doesn't find it, Settings / General / Reset / Reset Network Settings.
Phone will reboot. Give it more time to find the network.

Reinstalling the iPad BB ...sometimes... fixes this issue.

If it still does not work, uninstall Ultrasn0w. Reboot. Install ultrasn0w and hope for the best

Good luck.

I will try when I get home from work and post to let you know what happens.

Thank you again for all your help!!!

[Mes]

You're welcome. Hope this last-resort-option solves the problem.
FYI: 3.1.3 is really better on the 3G, but unlikely to have any effect on your no-signal problem

[fish ballz]

no luck

any other suggestions?

[Mes]

Sorry to hear that. What is the last thing you tried?
