My first hard reset of iPadI caused me to be stuck with logo for several hours, two or three months ago. After trying some methods, I’ve found the solution as posted. In order to avoid the confusion of hard reset, I’d like to clarify its meaning as following: Hard reset is to erase all contents & settings, but it’s not to reset the device by press & hold down power & home button.
At that time, I used hard reset for jailbreak. However, hard reset is not only for jailbreak, but for sell as we want our data not to be left in the device. Moreover, restore to the original settings is alternative for hard reset, but the data can be recovered by the technician.
During the same time of my first hard reset, I did jailbreak again on iPhone3G more than once. At the first time, it was successful with the changed baseband of 06.15.00. Actually, this phone was fine already, but unfortunately, there was the error from the other point later so the device needed jailbreak again. At the second time, the error occurred & it’s identified by the code of 1015 in the jailbreak process. This error can be corrected with iOS firmware which is custom for the step of shift & restore, preparing step for jailbreak. However, please be reminded that iOS firmware for redsn0w process is original.
