This is a custom recovery based on Cyanogen's recovery source with a lot of things added by me. The purpose of this recovery is to avoid using adb by accessing all features directly from the menu.

Use the trackball (up+down) to navigate through the menu, press the trackball to select items. Use the Volume-down key to go back to a previous menu.

Always check recovery.log before posting your issues!
Please make sure that your ROM supports apps2sd if you plan to use the ext-features! (/system/sd MUST be available in the ROM)

I’m a total nobble at this and I’ve spent hours trolling this board and others looking for the answer.

I’ve successfully unlocked the bootloader and rooted my nexus one but can’t get passed updating the recovery file.

Like I said. I’m a total Noobie. I’m presuming the recovery file is installed before I install Cyanogen 6 ROM

Johns-MacBook-Pro:fastboot johnlefevre$ ./fastboot-mac oem unlock
... INFODevice was already unlocked!
Johns-MacBook-Pro:~ john$ cd
Johns-MacBook-Pro:~ john$
Then reboot and placed the recovery-RA-nexus-v2.0.0.img on the root level of the SD card
Rebooted holding trackball.
Phone shows Fastboot USB highlighted in red
and Bootloader highlighted in blue

Johns-MacBook-Pro:~ john$ su
su: Sorry
Johns-MacBook-Pro:~ john$

Then I navigate to HBoot highlighted in Blue
and Recovery highlighted in blue

Johns-MacBook-Pro:~ john$ su
Password: (enter)
su: Sorry
Johns-MacBook-Pro:~ john$

If I press the power key with both Hboot and fastback highlighted in blue I get a scroll of green text which rapidly scrolls and then disappears. I can see that some of the entries are saying incorrect or wrong image

This is on a Mac using Terminal. So what am I doing wrong? Any help appreciated thanks

First, there's a more recent AmonRa recovery:


To install it:

Extract the recovery .IMG file to your desktop or preferably to the same location where the fastboot binary is.

Boot the phone to fastboot mode (the 3 skateboarding androids).

Connect the phone to the computer.

From a shell type;

fastboot flash recovery recoveryfilename.IMG

Obviously, replace "recoverfilename.IMG" with the name of the recovery file.

(this is the line "fastboot flash recovery recovery-RA-nexus-v1.6.2.img" from the instructions in the initial post that you've missed)

You will get a bar go up the right top corner of the fastboot menu, once you get a completed notification, tap the power button on the phone, wait about 10 seconds then press the "Volume Down" button once to highlight "RECOVERY" and then tap the power button again. You should then boot into the AmonRa recovery menu from which you can flash any update .ZIP files that are stored on the microSD card in the phone.
