Afternoon,
I have seen this a couple times now, devices that do not boot past the Apple logo.
Google seems to suggest that the solution is to restore through iTunes or take it to the Genius Bar. Neither are suitable for a forensic investigation!
Any one else faced this? How did you overcome this?
Cheers,
what is the device?
I have typically seen it on iPads

From my experience its usually file system corruption, straight restore will wipe the phone, you could use a custom firmware that is designed NOT TO WIPE the phone and do a restore, I had very good results with this method.
However I did that for data recovery, not sure how that would affect for forensics cases.
I have had this problem a few times and patience is a virtue. Try hard resetting with the home and hold button. Plug it in and prompt a power up, unplug the power lead, may take up to 40 mins - 1 hr to turn on in my exp. Normally boots normally again after this. Obviously it has to have a good charge in it to stay on long enough to self heal whatever problem it is having back end.
Alternatively, I have had a similar problem where the spring board dies. If it keep sitting in the logo screen. Try and connect into the phone using a tool which utilizes the AFC connection (I quite like ifunbox as it is free) and see if the phone is still functioning but not showing screen output perhaps. If you still cannot connect a flash may be in order!
NOTE this is all personal advice for fixing a broken device not a forensic recovery technique!
If you need to do a forensic analysis of the unit, try a full disassemble removing the battery will often fix recursive boot problems.
So pulling the battery out (for an hour?) then connecting it back up and giving it a good few hours on charge should sort out these boot issues?
Worth knowing!

Sounds highly unlikely.
Force fsck by restoring with a custom firmware that is setup not to wipe the phone, restore might fail but it will force fsck during the process, in which it will get the device running again.
Looking around the web I cannot find specific custom firmware bundles. Do you have any links to these? The custom bundles are all linked to jail breaking tools.
I wouldn't mind experimenting with them on our test phones to see how they work.

Also, there is no specific firmware that wont wipe your user partition. You have to make it yourself or do the custom ramdisk boot and go manually from there. As I said in previous post, PM if you have problems.
