IMEI: Unknown ICCID: Unknown, possible to back up?
I have a 3GS running 4.3.5 which has never been Jail broken. On Wednesday evening the phone lost all signal and wireless so I rebooted it to see if that would fix it. When it came back on it was stuck in the Emergency Calls Only loop (restore mode?) with the "IMEI: Unknown ICCID: Unknown".
From what I've read, it seems that my phone is essentially toast, my kid has lost his backpack, and I'm going to need a new phone. 'Course the problem is that I have data I want to get off it - always the way huh?
Actually, it's not that bad I have backed up recently, but as my daughter decided to walk for the first time that evening, I thought it would be nice to try and get the video of that off the phone at least.
Plugging into iTunes though tells me that the phone can't be accessed because it is locked by a pass code.
My first thought was to see if it is possible to bypass the passcode, and if that was possible whether itunes would activate the iphone or at least back it up.
I've found a few posts online such as Working ramdisk with ssh, but they all seem to be a little out of date. I started the steps in that process, but iphone wiki doesn't seem to have any codes for 4.3.5 yet, so I was unable to generate the ramdisk (I guess because 5.0 hasn't been released yet for the keys to be extracted?).
I also looked at jailbreaking, but I'm guessing that that would wipe the device, which isn't what I want to do.
I figure that I likely have one shot at this without hosing the data on there. So I thought I'd turn to the community first to see if I had any options.
So, what are my options at this point, do I even have any?
Solved - got a backup!

Just a note though, I was treating the phone H/W as toast and my objective was never to return the device to a working state. The only thing I wanted was a recent backup of the phone (I have a iPhone 4S which I restored the backup to). I may try to repair the phone once I have some down time, at this point I have a new battery (which I'll need to perform a full restore to test) and I also have the option of trying the "reflow" heat gun treatment.
My steps to get the data off though:
- My F/W version was 4.3.5 so I jailbroke the phone with redsn0w 0.9.8b3 as per this article, this seemed to get past the connect to iTunes and emergency calls only screen. I was now able to access the phone. At this point I turned off my passcode which iTunes had been complaining prevented it from backing up. However, the phone would constantly turn off after 3 minutes and none of the applications worked.
- Plugging into iTunes to try and back up threw up the following error "Itunes cannot read the contents of the iphone. Go to the summary tab in IPhone preferences and click restore to restore this iphone to factory settings". However a quick search on the internet gave me this site and a fix. Having installed iExplorer and deleted the iTunesDB and iTunesCDB I was able to connect to iTunes again. The phone began to back up ...
- However, at this point my phone's 3 minute boot cycle began to get in the way. My backup was taking longer than 3 minutes. At first I tried to use iFun-Box here to take the applications and data I wanted individually as suggested here. This didn't work out quite as planned as though I was able to get the data off the broken phone I wasn't able to use iFun-Box to put it back onto the new iPhone (itis supposed to be able to backup and restore valid apps and data without a jailbreak, but I suspect that iOS5.0 has changed the game slightly there).
- so I then started to look at tuning my backup to speed it up. I had to delete data and apps in stages as if I didn't leave around 30 seconds before the phone rebooted (or I rebooted it) then the deleted data/app would return on reboot. It took a few attempts, but by removing all the apps and pictures that hadn't changed since my last backup I was able to get a backup speed that gave me plenty of time to get all the data off.
- It was then just a case of restoring my backup to the new iPhone in iTunes. For some reason this didn't delete any of the data that was already on the phone (I'd set up the cloud restore which iTunes was now syncying to) and I now have my phone set up exactly as it was before it died.
A note on the battery: When the phone is in the recovery loop it doesn't take a charge, more so after jailbreaking. As such you'll have limited time to get the data off. I'd ordered a new battery to see if that was the issue, as it turns out that didn't help (apparently I'd need to perform a full restore to set up the battery which wasn't my objective) but it did give me some valuable extra time to run down some charge.
I hope this helps someone who finds themselves in a similar situation. As mentioned, I may try playing around with the h/w to repair that if I get some downtime as some point. If I have any luck I'll add to this thread.
