I recently bought an iPad 2 from a second hand seller, the iPad works great overall and since I was able to downgrade the firmware on the iPad 2 to IOS 6.1.3, I thought it was a great find. After a few attempts of loading the signed IOS 6 iPsw file I saw no result. I realized that my iPad that I bought was a Mid-2012 Model, which can't be downgraded. I was wondering if I can somehow modify the signed iPad ipsw to be able to downgrade my Mid-2012 iPad 2. Is that possible since the firmware are pretty much identical?
