Within a day’s release of Nexus One, we have seen a successful ‘Root’ and now a Recovery Image which empowers you with nifty features like creating/restoring a backup, flashing the radio, flashing a custom ROM and many more. It has been an exciting day for the Nexus One!
The famous Amon_RA from Modaco released the recovery image for Nexus one earlier. Here are the steps you should follow to flash this recovery image v1.5.3.
- Download the recovery image from Modaco.
- Download this file (Rapidshare). or you can also download them from here(modaco). Extract them to your desktop. You will see two .zip files, extract them both. Place the .img file downloaded from step 1 into the folder ’1.1-nexusone-superboot’.
- Connect the Nexus One to your PC/Mac and turn it off.
- Hold the volume down button and hit the power button (while holding the side volume down button). You should see the following bootloader screen (with the word unlocked on top).

- Hit the power button once to select the fastboot usb option. Now you should see ‘FASTBOOT USB’ in red.
- Now from the files you downloaded from step 2, you will see a folder called ‘1.1-nexusone-superboot’ (if you extracted 1.1-nexusone-superboot.zip that is!).
- On a Windows machine – launch the Command Prompt and CD to 1.1-nexusone-superboot folder (type in ‘cd ‘ and drag and drop the folder. Now hit enter.). Type the following (without quotes): ‘fastboot-windows flash recovery recovery-RA-nexus-v1.5.3.img’ and hit enter.
- On a Mac or Linux machine – launch the Terminal and CD to 1.1-nexusone-superboot folder (type in ‘cd ‘ and drag and drop the folder. Now hit enter.). Type the following (without quotes):
- MAC - ’./fastboot-mac flash recovery recovery-RA-nexus-v1.5.3.img‘ and hit enter.
- LINUX – type ‘./fastboot-linux flash recovery recovery-RA-nexus-v1.5.3.img‘ and hit enter.

- Congratulations, you just installed the recovery image! You can now create nandroid backups, flash updates and lot more!

I just want to give you a thousand fucking kudos for this tutorial. This is THE ONLY tutorial on the internet that gives a clear a concise set of steps.
Thank you!
I am glad it worked for you buddy! Enjoy!
when i try to flash the cyanogen mod in recovery mode – flash from sd card – it gives me the error E:No signature (1593 files) E:Verification failed HELP
i am also getting the same error, any fix or solution
I agree. This is the clearest and best tut for rooting the Nexus One. You're a legend.
I have no idea what the recovery file does but I've spent hours trying to get to this point.
The next step is what tho?
I've been told that the Cynogoen ROM is the best to install. Have you written a tut for that?
Cyanogen ROM is the best way to go. Install ROM Manager app from Market and download Cyanogen ROM from there. It should be straight forward. If you have any problems, let me know…Cheers!
Thanks very much Kiran. With FRG83D the restart installs a Super User app but it doesn't automatically load. Once I found that I knew all was good and then downloaded N1 torch which has a component that needs Root.
Then got ROM Manager and installed the Flashwork Mod Recovery
Backed up the existing ROM
Started downloading CyanogenMod 6.1.0
Sorry to repeat the same details in 2 threads but they sort of follow on.
Hi Kiran,
Before you go to any trouble writing up a detailed reply. I've solved the problem. I downloaded the files and transferred manually to my SD card and then zipped into Flashwork mod Recovery and all is good. I had previously installed Amon RAs recovery-RA-nexus-v2.0.0 so that could have caused the problem. IN any event Ccyanogen 6 is now installed and running nicely.
Thanks very much.
This really is the most clear and concise guide for unlocking and rooting the Nexus One for Mac or PS users. – Hope those keywords help
Cheers,
John

I can't get past STEP 11. Everytime I press the power button on RECOVER option, I get a triangle with an exclamation point and a little android standing next to it. I CANNOT access that green recovery mode. Please help me.
My email is: paulorona@gmail.com
Thank you
i'm having the exact same problem.. anyone with a solution?
john2kx@gmail.com
On step number 7, I received the following error: 'fastboot-windows' is not recognized as an external or internal command. did i miss a step?
Also, the img file that I downloaded is version 1.7.0 – does that make a diff?
Thanks
What all do you see when you type 'dir' without quotes? I feel you didn't change directory to the required folder (cd)…
There is no harm trying with this version. I would suggest download the files mentioned in the post for better results since I have verified them…
NVM I figured it out! Thanks!!!
