[Urgent] Help required with iPhone 3gs (weird issue)
 

Okay so there it goes..(But please reply only after reading the whole thing)

4 days back I decided to Jailbreak my 2 weeks old iPhone 3gs 8gb (newer version) and went ahead with installation of CFW 4.3.3 using PawnageTool and Macbook Pro.

Everything seemed going well until the phone didn't restart post installation of the new firmware.

I have tried it 100000s of time till now using different techniques like using TSS server on Tiny Umbrella + iTunes or using iReb + Tiny Umbrella + iTunes or Redsn0w = going for "just go into DFU mode for now" method both with and without editing "etc/hosts"but absolutely no success.

Either I get 1015, 1600, 2100 or 3194 error and if I am not getting any error, FW (both Custom and official) installs smoothly but when it shows on iTunes that "your phone will restart now" along with countdown just after FW has been installed successfully, iPhone dies down and goes back to DFU mode.

NO sh blobs were saved for it either.

Its totally stuck in DFU mode, I cannot see any screen or anything.

If I try fix recovery from Tiny Umbrella it shows Unable to load fs_mount, fs_unmount ..etc.

I can say I have tried every possible method of this planet and its still not working and is still stuck in DFU like forever.

If anybody has any solution please help me out.

BTW Phone is under warranty as its hardly 2 weeks old, but I wish it starts as it is.

I am having same issue as this guy "http://*****i.com/forums/redsn0w/775174-dead-iphone-3gs.html" and maybe its a coincidence he is having the same problem in the same month, maybe a new issue? :-/

Just tried ifaith and it keeps showing "unable to find byte sequence". :(

hi brothers,

the problem is you don't have shsh saved for the desired version of firmware. so the best way is just you can install 4.1 firmware without shsh now. because apple still signing 4.1. but you don't have to use tinyumbrella for that process. just restore with original 4.1 firmware, before doing that you just have to modify the host file.
follow this tutor....

* Quit iTunes
* Locate your hosts file, in Mac OS X this is /etc/hosts and in Windows this is c:\windows\system32\drivers\etc\hosts
* Open the hosts file with Administrator privileges
* remove the following lines to the very bottom of the hosts file:
* 74.208.105.171 gs.apple.com or XXXXXXXX.gs.apple.com
* Connect your iPhone to the computer
* Launch iTunes
* Put the iPhone/iPad/iPod into DFU mode by turning the phone off and then holding down the sleep and power button for 10 seconds, then release the power button but hold onto the home button until iTunes tells you that the device is now in recover mode
* Use the iTunes Restore feature as usual with the iOS device

Note: but finally you will get error 1015 which is normal and phone will start with itunes logo. then just use tinyumbrell to kick out of recovery..thats it...

this will solve your problems....

Love you for this brother, it worked like charm. Finally I can use my phone after almost a week.

Can't thank you enough. :)

you r most welcome dear....

Hey,

Thanks for helping through my problem previously bro.

Now there is another problem :(.

I am having problem with my bluetooth, its stuck on searching, I have tried restarting, etc etc but it just doesnt work and is stuck on searching.

I am on OS 4.1 and read online that such problem persists in iOS 4.0.2-4.1 and I think this is it.

Now i tried upgrading to 4.3.3 first by making hosts file as it was before and trying to install it directly via iTunes and got error 3194 just like before and later I tried it by changing hosts file then turning on TSS server on Tiny Umbrella and putting it into PwndDFU mode using iReb and then trying to restore it using iTunes and again facing the issue where it installs 4.3.3 till almost 99.99% and then it agains goes into DFU mode.

I want to update it to 4.3.3, please help me out :(.

hi dear just go back to 4.1 because if you did not save your shsh blob. you wont be able upgrade t0 4.3.3

is apple signing it for iphone 4?
 

Hello i've the same problem with my iphone 4. i didn't save any shsh blobs & its lost i think. So i needs get my iphone back in normal. what can i do now?? plzzzzz help... :-(
