Well, if you've indeed tried EVERYTHING, then you'll need to bring your phone to Apple for evaluation.

my ipad i have been restore it yesterday my computer shut down in the middel now my ipad2 stuck in recovery mode and cant be detect by itunes and it is jaikbroken ?
Try these steps. If it doesn't work the first time, try a second time.
Disconnect the USB cable from the iPhone, iPad, or iPod touch, but leave the other end of the cable connected to your computer's USB port.
Turn off the device: Press and hold the Sleep/Wake button for a few seconds until the red slider appears, then slide the slider. Wait for the device to turn off. (If you cannot turn off the device using the slider, press and hold the Sleep/Wake and Home buttons at the same time. When the device turns off, release the Sleep/Wake and Home buttons.)
While pressing and holding the Home button, reconnect the USB cable to the device. The device should turn on. (Note: If you see the screen that shows you are out of battery, let the device charge for at least ten minutes to ensure that the battery has some charge, and then start with step 2 again.)
Continue holding the Home button until you see the "Connect to iTunes" screen. When this screen appears you can release the Home button
If necessary, open iTunes. You should see the following "recovery mode" alert: "iTunes has detected an iPhone in recovery mode..."
Use iTunes to restore the device.
If you don't see the "Connect to iTunes" screen, try these steps again. If you see the "Connect to iTunes" screen but the device does not appear in iTunes, see this article and its related links. http://support.apple.com/kb/TS1538
Hope this helps!

Thanks anyway for your help.
But allow me to extend to you a simple reflexion about the jailbreak (even if my iPhone wasn't... except if my little cousin jailbreaked without me noticing the advantages or disadvantages) : Would you refuse an alcoholic trying to go to rehab ? Would you really let someone trying to restore a cellular phone die without it, because he went on the bad side a couple of years ?
Not a great analogy, but this is a user-to-user forum, and Apple will not allow discussion of jailbreaking; if someone tried to help with jailbreaking the message would be deleted. However, if you have a jailbroken phone Apple will generally not block a discussion of how to unjailbreak it. The only problem is that not all jailbroken phones can be restored successfully; it depends on the method of jailbreaking (which I can't discuss without THIS message being deleted). -
I get missing plug-in error when opening my online bill which is in PDF format. I am using a 2010 Macbook with the latest version of Safari and Adobe suite installed in my computer. Why do I get this error? What should I do?
In relation to my previous inquiry regarding inability to view a pdf file using Safari...
Is it possible that I can view other online bills from other website but not this particular bill from one specific website?
Sorry if I missed any important point in this article -->Apple Safari 5.1 and Adobe Reader/Acrobat Advisory
Thanks again! -
my iphone 3g fails to restore. i have tried to restore many times and in different computers but at the end of the restore process it keeps giving me an error message- 1015. can anybody help? thx.
The phone was jailbroken. That's what that error indicates. You can't get help here. You can't get help from Apple.
Try Google. -

Someone tried to jailbreak my iPod and now it is stuck in recovery mode. How do I fix it?
I'm not sure what jail breaking is, however one of my friends insisted on jail breaking my iPod, 4th generation. Now it is stuck in recovery mode and everything has been wiped out. I had backed my iPod up to my computer before everything happened. Thanks for any help!
I suggest that you find a new friend. Based on the experiences of others, the jailbreaking may well be non-reversible. Here are some things to try...
Restore...
Connect via cable to the computer that you use for sync. From iTunes, select the iPad/iPod and then select the Summary tab. Follow directions for Restore and be sure to say "yes" to the backup. You will be warned that all data (apps, music, movies, etc.) will be erased but, as the Restore finishes, you will be asked if you wish the contents of the backup to be copied to the iPad/iPod. Again, say "yes."
If the Restore doesn't work, let the battery drain completely. Then recharge for at least an hour and Restore again.
I really don't want to recommend the next step because it's a real PIA after the fact. However...
Restore as new with NO reload from backup!
IF you choose to try it, here are some cautions. Make absolutely certain that all purchased data, such as apps, music, movies, etc., are present in the iTunes library. Also make absolutely certain that all non-purchased data, such as photos, pdf files, Word files, etc., are present and accessible somewhere on the computer's hard drive. Be aware that you will lose all game data (scores, etc.). Be forewarned that it is tedious recreating all your folders and putting each app where you want it. Finally, be aware that all passwords will be wiped out and all settings will have returned to their default values. -
