I have a jailbreaked iPhone 4 and I updated from version 5 to v6 in wifi.
The screen shows only the recovery mode, but when I connect it to iTunes, it detects the iPhone but needs to update it.
When I restore it to the last version or to v6 I get a restore error 2009
I tried with 2 different computers (win7-8) and 2 different cables, but I still get this 2009 error.
I tried to enter DFU mode with redsnow but it didn't work, as the power button doesn't work, and it showed again the recovery mode.
Any thought ?

You can try entering DFU mode by using the DFU IPSW feature with redsn0w.
From what I understand it will create an IPSW and you can click Shift+Restore in iTunes, point to the IPSW redsn0w made and iTunes will put your device in DFU mode.
From there you can try restoring normally with iTunes.
