As our geeks reported, some times they are experiencing an issue that impacts Apple tablet's capability to restore the original firmware that is iPad / iPad 2 / iPad 3 and, imagine, new iPad mini / iPad 4 may get stuck during the recovery mode, it won't restore and won't reboot in iTunes. The problem may come from corrupted Apple Mobile Device (Recovery Mode) drivers and the signal for this are the yellow exclamation marks near the entries that describe those drivers in Device Manager on your PC. If so and you are absolutely sure that PC is not infected with viruses follow these tips on how to fix Apple tablet that get stuck in recovery mode:
Your iPad / iPad2 / ipad 3 / iPad mini / ipad 4 may hang during an operation of restore because of incorrect setting for the size of default TCP receive window that specifies the number of bytes that Apple’s servers can transmit without receiving an acknowledgment. This may be an issue when not correct value for TcpWindowSize parameter is set up by third party software. Look into HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters registry key. If TcpWindowSize is there (by default it should not be) try to delete it and restart Windows. After this Windows will use the default value for TCP receive window. Follow these steps to put iPad into recovery mode once more.
Another problem your iconic tablet may stuck in is a perpetual recovery mode that has the symptom of a loop, that is after Apple tablet has been restored it restarts by itself, and prompts the same thing again.

If you did not follow our advice on update and your iPad ended with device stuck in recovery mode (the reasons for this are numerous, more common are the iTunes version you use is too old to fit the latest firmware, firmware you / iTunes downloaded is somehow corrupted, kennel panic etc) the best option for you is to flash firmware manually via DFU mode working at a lower level in the bootloader environment without any interaction with iOS. This is the very reason why it saves you from a corrupted firmware because it is not a part of the iOS firmware at all.
Very important: before flashing iPad via DFU check once more for the latest version of iTunes. If it is installed restart your computer (iPad must be disconnected and turned OFF). Manually download the Apple firmware and save it in the directory with the short pathway. Make sure the firmware you downloaded fits the model of your iPad and any antivirus software on your computer is disabled! Make sure you use USB port and USB cable that are both functional. Your computer must be connected to Internet!
