How to exit recovery mode on iphone 4s beyond repair?

I tried to update my iphone 4s to ios 7 but forgot it's jail broken and now it's stuck in recovery mode. When I try tinyumbrella "exit recovery", it goes to the apple logo and then a blank screen. It's been doing this for recboot too. I don't have any backups of my iphone's data but I really want to retrieve the data on it!

I guess you have to go either for repair or to get a new one. For the backup, it is too bad then, just rem to backup data next time. Also, i heard about some software which have the possibility of retrieving data, knowing the photos but not sure about other. Maybe can try searching the net.

The thing you should always do before updating your software is to backup all the things on the computer through iTunes or use dropbox or iCloud. Something like this has happened to my dad's iPhone 4s. He updated his software on his phone and it crashed. He had to restore it through iTunes. Because he didn't backup he lost everything on his phone. There really isn't really anything you can do to get back what's on your phone. Sorry.
