(adsbygoogle = window.adsbygoogle || []).push({}); What happened is i wanted to downgrade the iphone and finally it got to doing it but then after stopped. And now its stuck in recovery mode i fink.

Ive tried holding the home button and plugging in the dock but it doesn't want to turn on.

Also how much would a iphone 4 like this cost in its state ?

And seriously it don't turn on.

Thank You.

Connect iPhone 4 to Mac/pc
Turn off the phone
Hold lock button for 5 seconds.
Keep holding lock and press home button for another 5 seconds
Then release lock and keep holding home button it should get recognized by iTunes. You cant downgrade an iPhone since new security measures at apple require you to have internet that sends a message to apples servers. If you try to downgrade apple will reject you and iTunes will not let you downgrade. The only way to downgrade is by saving your shsh blobs in Cydia if you did then you shouldn't have had this problem. Next time when you jailbreak save your shsh blobs or use/download tiny umbrella for Mac.

Some time while jailbreaking and unlocking process iPhone refuses to boot in normal mode and every time you restart your iPhone it enters in Recovery mode.

This situation is named as recovery mode loop. If you are in a recovery mode loop (i.e. your phone enters recovery mode on every reboot.

To get the out of recovery mode loop use iRecovery

iRecovery is a libusb-based command line utility for Mac OS X,Linux and Windows. It is able to talk to the iBoot/iBSS in Apple’s iPhone/iPod touch via USB.

If you are on Windows then you need to install LibUsb-Win32 in order to run iRecovery.

LibUsb-Win32 is a port of the USB library libusb the Windows operating system. The library allows user space applications to access any USB device on Windows.
