Hi,

    after few failed attempts of entering passcode my iPhone got disabled and it shows as connect to iTunes .so, took device to recovery mode using iTunes and clicked update so, now software updated and it showed as "try again in 60mins" error so, after this 60mins I entered passcode two times then it tried recovery for some time and give as "recovery failed" screen and stuck there only.so, did restart of device and again now shows as "iPhone disabled, connect to iTunes". so, again I did followed same process of taking device into recovery mode and updating through iTunes but it again stucks at data recovery failed after it try attempting to recover data for some time upon entering my passcode.

Please be noted I do not have backup data in iTunes or iCloud so, I want to retain data.

is there any software that helps me in this situation? if so, please tell that software and also tell which method I should go
