iphone 3g stuck in dfu and will not restore

[wolrabn]

Hi guys,

wondered if someone can help at all. Have searched the net quite extensively with this one - I'm now under the assumption the logic board will need replacing unless anyone can tell me otherwise?

I'll list as much info as I can if you need anything else let me know.

Got an iPhone 3g from a friend that only powers in DFU mode when connected to the mac/pc.

Blank screen permanently on.
All restores return error code 6.
2 different usb cables tried, tested on OSX 10.6.7, windows 7 + sp1 and xp sp3 (xp is virtual).

I do not know what version firmware was previously on it.
I have tried to restore official 2.0.1, 2.1, 3.1.2, 3.1.3, 4.1, 4.2
I have tried custom firmware on 3.1.3, 2.1, 4.1

I have attempted jailbreak with redsn0w, pwnagetool, ziphone
redsn0w seems to work then instead of booting to springboard the iphone just reverts back into dfu.

I have checked the logs of these restores and noticed this:
Error setting variable - 'boot-args': (iokit/common) general error
error setting 'boot-args' to '': 1

to which a little googling led me to a possibility with logic board.
I have tried using iRecovery but to be honest unsure where to go with it i also tried TinyUmberella which attempted to fix recovery and the phone didnt reboot. just stayed in dfu.

Although this is in DFU i have kept making a point of making sure i manually place it into DFU when attempting restores just to make sure its not in recovery mode (though i doubt it ever has been as it has never shown the 'connect to itunes' message- just always a blank screen unless recovering.

Recovery for all firmware seems to get 99% of the way before showing error 6.

Does anyone know a way of fixing this issue or do I give up and sell for spares/repair?

Thanks

Surely someone had experienced this or a similar issue? Booked in at the genius bar on Friday but hoping someone could shed a light on it before then..

Was it unlocked with the iPad baseband?

Thanks for the response,

In all honestly that's something I'm not 100 percent sure on. The guy that had the phone before me knows nothing other than how to use it and as its always been in dfu I havemt been able to check. However as I have jailbroke with redsn0w on cust firmwar 4.2 I would assume its been updated to the ipad baseband? Although as it reverts back to dfu I can't even be sure the jailbreak has been succesful....

Rather puzzled by it to say the least. I've done some reading on using iRecovery so going to try that later on and see how it goes- I'm ocd when it comes to fixing stuff like this so really don't want to call it quits!!

Do you think the baseband would have an effect on it failing restores?

Yes, if it has the iPad bb it won't restore to official firmware.
Only to custom jb Ipsw.

 

[wolrabn]

It's not restoring to either though, I've created a few c.firmware packages with pwnagetool - all returning same error code 6 as official.

 

[wolrabn]

still not given up.. though its fading.
i've now tried custom firmware making sure im in pwned dfu mode for 2.2.1 and 3.1.3 using both pwnagetool and sn0wbreeze.

all return error 6.

tried using itunes 7.7 on windows but that cannot connect to software update server...

im pretty certain its not on ipad baseband now. i've added the ecid to tinyumberella but it doesn't see it and 'fix recovery' option fails.

also tried using ireb then sn0wbreeze custom firmware- no joy.
tried pretty much all official firmware.

has anyone seen this sort of error before and it be hardware related?

 

[Applejuiced]

It might be hardware issue.

Have you tried irecovery? If you havent you may want to look into it. I had a stuborn 3g stuck in the apple logo boot loop and irecovery got me out. I then used redsn0w_win_0.9.6b6 with firware iPhone1,2_4.2.1_8C148_Restore.ipsw and then ran custom firmware iPhone 3G Custom Firmware 4.2.1 8C148.ipsw threw itunes.

I put this down to hardware.. and sold it on as faulty. Never got it fixed I'm afraid.
