Possible To Downgrade iOS4 to 3.1.3?

**CaptainNegatory** · 07-16-2010 11:27 PM

Hello Peeps,
I've had iOS4 for a couple weeks now. I hate it. Somehow for some reason not only does my phone get laggy and force me to reboot to fix it, but I have to start some apps 3-4 times before they run, crashless. So I've restored iOS4 and redone my Jailbreak and Unlock. Now, I fixed "MOST" issues but still my favorite app, WeRule does not work. That being said, I'm sick of this iOS4 and was wondering with the bb 5.13.04 is there anyway I can downgrade back to 3.1.3 and redo everything, hopefully for one final time. If you know a solution to my problem without downgrading, please, let me know.

Thanks Much,
C. Negatory

I used this guide

It worked on 1 iphone but not the other...

Were both phones 3G? or was one a 3GS? What error did you get?

Yeah they were both 3G, I'm not 100% sure what the error code was, but I had to run iRecovery on the second one to get it to boot again, and it didn't downgrade, on the first one I had no issues.

It belonged to friend of mine, so I can't try again right now... very likely I'll try again at some point, I'll post then what the error is.

I don't have the iPhone I was trying to downgrade. However I have another one that's giving me issues...
I have posted the details here

I'll post the restore log in a minute, allow me to run the restore again just so that I'm sure I'm posting the right log.
