[1.1.3 (1.1.2otb)] Can't enter DFU mode
Hi all, I have a 1.1.2OTB phone that I upgraded to 1.1.3 using itines, followed by jailbreak, activation and unlock with Ziphone. So, I now 1.1.3 software with the previous 4_02 baseband. I would like to now do a restore to 1.1.2 to bring it back to 1.1.2OTB condition, however when I attempt to bring the phone into DFU mode, it perpetually ends up stuck in restore mode (with the connect to iTunes logo) and can only be kicked out of that mode by using iBrickr. I have also attempted to get the phone into DFU mode using iNdependence, however it goes into restore rather than DFU mode.
Any ideas what I can do to get the phone into DFU mode so I can actually restore a firmware now?
Note that I did try to search, but the forum search complains that 'dfu' is too short to search on ;) I have 4.6BL by the way.
