Hey Guys,

Last night, I took the painstaking steps of forcing my iPhone back into 1.1.4. No luck with fixing the problem. It was running 1.1.4 just fine, but still had the bug where it shuts itself off. I couldn't believe it!
My last attempt will be forcing it down to 1.1.3, which is where I started before I pwned up to 2.0.0. Good luck to all of you and your various attempts in the mean time.

has anyone trying downgrading to 1.14 or 1.1.3 and it not shutting off?

[MRemingtonB]

All right everybody, here's the final verdict.

Downgraded to 1.1.3 today... and... still shutting off for no reason. That's really it, there's nothing else to be done that I can think of, unless a fix comes around through pwnage. I'll post if anything happens, and I'll keep checking this thread for any tips that you guys come up with. Good luck.

here is a thought that I have considered trying as sort of a last ditch effort what boot loader do you have? I still have 3.9 so im thinking about trying to upgrade to 4.6 to see if it makes a difference.

[MRemingtonB]

Sorry Phishnchips, but no joy. I like your thinking, for I tried the same thing. I switched my bootloader and baseband around multiple times, in different combinations, with no change in the shut down glitch.

The fact that I changed the OS to 1.1.4 and 1.1.3 with no change in performance suggests to me that we really screwed up our phones big time. This would imply that there is a bug somewhere in the very root of the iPhone OS, something that isn't swapped when you upgrade or downgrade the OS. I'm not a programmer, but it is akin to the kind of data that would be present in a computer without an OS. Something that still lets it boot, but it won't be able to do much else. In other words, something saved in the RAM, maybe? As opposed to the harddrive.

I had a peek around the system using OpenSSH, and needless to say, I didn't find anything. Messing with the baseband and bootloader is the closest thing I can think of to messing around with that "other" section of the iPhone that we can't modify just by changing the OS. My suspicion is that the mechanism that controls the turning on and off of the iPhone is simply not saved in the iPhone OS, but somewhere else, as I point out above. In which case, rubbing the iPhone with a magnet will probably be the most productive thing that I can think of.

Anyway, good luck!

just wondering if you when you guys upgraded if you did not have auto lock set to never. I did not when I upgrade and when the BootNeuter 2.0 ran the auto lock came on and I had to slide it open. i was wondering if that is what may of messed it up.

any thoughts?

[MRemingtonB]

Hey Strike,

No, I always watch out for that. It didn't lock during the upgrade at any point. Alas, back to the drawing board we go! Good thinking though.

[phishnchips]

if the phone is plugged into a power source or if it never locks then it stays on. I guess since you already tried the bootloaders im not even going to bother. sucks that this really is the only phone worth using. I have grown tired of it that and everyone and their brother has one. Guess I just have to patiently wait on tmobile to roll out a 3g network and hope we get the HTC touch diamond.

my problem after pwnage 2.0 was that my phone would just crash after i installed something from cydia, but after it would not boot. It would just show the apple logo for several minutes. The only thing i could do was restore it. and it has happenend over 15 times!!! plz help!!

[MRemingtonB]

Hey there gVes,

A number of things can cause that to happen, but lets start with the most simple one first. When you open up Cydia for the first time, do you allow it to apply the updates, close Cydia, open it, let it reboot, and THEN download new files? If you look at the command script, it requests a reboot of Cydia before you do anything else. Not doing so can send it into weird booting modes.

Has anyone accually fixed this at all. I want to sell my old iPhone as I got a 3G one, I have no need for the 1st Gen one...

Since the 1st Gen one is the one with the problem of randomly shutting down in stand-by, it will lower its value...

i pwnged my iphone with winpwn if i shut it off completely i can't reboot at all. i have to connect it to computer and open winpwn when it starts then it reboots my iphone. also i can't use ibrickr to change sms sound because it says version 2.0 is too old

[MRemingtonB]

Hey Guys,

Just an update. Upgrading to 2.0.1 official FW has no effect. Still fiddling around.

UPDATE: Well, after upgrading, my iPhone is officially a brick. It won't turn on at all now. I guess that's not so bad. I can probably legitimately bring it to the Apple Store now.

hi there,

have the same problem, iPhone shuts down shortly after the keylock went on (iPhone 2G, Firmware 2.2, jailbreak + unlock).

By accident I think I have come across a solution (well.....kind of). I installed the little app "insomnia", which prevents your iPhone from going into eco-modus. Its main function is to keep WiFi on, when the keylock is on. Well, it seems to have solved the problem (WiFi on or off, doesn't matter). Probably batteries are going to be drained a lot faster.

So, everybody try that and maybe this leads to more sophisticated solutions.

cheers

same exact problem on every post.. i have firmware 3.0 an it does the same thing just shuts off by itself..

has anybody contact apple and tried to get some amswers?
