As of late, CyanogenMod developers have been busy releasing nightly builds for several Android devices including a version for Nexus One so if you are a Nexus One owner and want to update to the Gingerbread based CyanogenMod 7 without waiting for the final release, you can install the latest nightly build on your devices now.
We are more than happy to feature the latest nightly builds of our favorite custom Android ROM. We have been ourselves using a nightly build for our HTC Desire (which is pretty much identical to Nexus One at hardware level, being its HTC-branded version) and have so far found it exceptionally stable for a nightly software. If you want to know more about these nightly builds, head over to our feature on CM7 nightly builds.
Disclaimer: Please follow this guide at your own risk. AddictiveTips will not be liable if your device gets damaged or bricked during the process.
Installing any version of CyanogenMod 7 requires ClockworkMod Recovery 3 or later on most phones but that isn’t the case with Nexus One and you can install it by using the latest 2.* version of ClockworkMod recovery as well.. In case you haven’t installed the latest recovery on your phone, you can install it by following the ROM Manager method in our guide on how to install ClockworkMod Recovery. In case you do come across a ClockworkMod 3.* recovery image, you can use the manual method in the same guide to flash it as well. (Update: ClockworkMod 3+ is available through ROM Manager’s automatic installation now, so this shouldn’t be a worry anymore.)
Once ClockworkMod is sorted out, you are advised to install the HBOOT 0.35.0017 to your phone by downloading it from the link given below and flashing it from recovery, as suggested at this XDA-Developers forum thread. You then just have to download the latest version of CyanogenMod 7 nightly build from the link given below and flash it to your phone from recovery, though first take a nandroid backup and wipe data, cache and Dalvik cache.
After installation of the ROM itself, you can install Google Apps in a similar manner after downloading the zip file from the link given below and flashing it from the SD card, though wiping data is not required here.
