I have an OTB 1.1.2 (new bootloader) which i upgraded to 1.1.3. How to I restore it back to 1.1.1? I put it into DFU mode and did the shift + click for restore, chose the 1.1.1 firmware, and waited for it to downgrade. When the software was done extracting, iTunes said that "an error occured (1)". What's the problem, and how do I fix it?
