Ok, lets go step by step. I've rooted my phone, now trying to install CM7. BUT there's a problem, my phone is behaving strangely. I've installed ROM Manager and ClockworkMod. Now I want to reboot into recovery so I could install update.zip. When I click "OK" my phone reboots to this: (Same thing happens if I try to install ROM form SD Card or download ROM, and also if I try to backup current ROM.) Whatever I do, my Tattoo allways goes into normal recovery. Then I click "HOME" + "BACK" buttons and "POWER" button and get to this: (volume down + power button doesn't work) So, as you see my phone didn't boot into Clockwork recovery. Here I choose to apply sd card update.zip and get this: E: No signature, E: Verfication failed Help?
