mattc's NexusLeo v1.1

This is a brand new build. It is almost a complete opposite of my Sense build. The base for this ROM is from Google's official Nexus 2.2 Froyo FRF91. This is *stock* Android.

The kernel is michyprima's overclockable to 1190.400MHz and undervolted to 925mv. It also has the latest GIT updates. I found this combo to be the most stable while producing amazing speeds. michyprima's post can be found here: http://forum.xda-developers.com/showthread.php?t=756513.

What's Not Working:
  • WIFI tethering
  • Bluetooth Headsets not working for calls. Streaming media is working fine.
  • USB Tethering
  • PPP

What is working:
  • Bluetooth Streaming Media
  • Wifi
  • EDGE/3G/HSDPA Internet
  • 5MP Camera w/flash
  • Standard Definition Camcorder w/flash
  • All other items working on other builds, too many to list

Known Issues:
  • Internet can be slow. This is because of the use of RMNET and should be fixed in future builds.
  • There are occasional touchscreen freezes. With the new kernel I have noticed a decrease. Normal touchscreen functionality usually returns after 10 seconds or so.

  • Use SetCPU to overclock. The max default is set to 998MHz.
  • Turn off live wallpaper for better performance and battery life.
  • Don't use the built-in USB Storage capabilities. While it works, it may cause corruption of your Android system files requiring a fresh install.
  • Use a program called "droidexplorer" which safely transfers files using adb.
  • I have included a Task Manager. Learn to use it religiously to improve battery life.

Other Notes:
  • CPU scaling is enable by default without SetCPU. There is nothing you need to do to overclock it is enabled by default.
  • This is a VERY basic build. Don't expect to see any Sense widgets, apps, etc. Check out a stock Nexus One and that is what you are getting.
  • I have included Astro File Manager as well as a Task Killer.

Installation Instructions:
  1. Download which build you like. You can choose from a 512MB, 1GB, or 2GB storage option.
  2. Unzip the contents to your SD card. All of the files should extract into a folder named "Android".
  3. Use an autoloader or, in Windows Mobile, browse to the Android folder on your SD card and run CLRCAD.exe, then Haret.exe.
  4. Let Android boot. The first boot is always the longest and larger data sizes require longer times. The 2GB can take up to 20 minutes depending on your card speed.
  5. Enjoy Android.
  6. Note: If you are having a looping boot issue, please replace the startup.txt with the one attached at the bottom of this post.

Changes to kernel logged by huanyu:
In this kernel, I have enabled the follows:

•Conservative CPUfreq governor
•Conservative governor is the default CPUfreq governor
•Voltage goes down to 1000 mv (zImage_1000mv) or 925mv (zImage_925mv) or 1050mv (default voltage)
•Overclocking to 1.113 GHz max.
Remember, I hold NO responsibility for anything that goes wrong. I'm simply providing the kernel, whatever happens with it is on your shoulders not mine.

If you do not like the overclocked feature, you can use SetCPU to disable it.

minor tweaking to drivers/cpufreq/cpufreq_ondemand.c

minor tweaking to drivers/cpufreq/cpufreq_conservative.c

Thanks to all of the devs working on kernel. Also, thanks to Darkstone and shu8i for their great work and support on other builds. Shatterv2, ShadowFoxBiH, and BazGee for beta testing. Mom...

As always, donations are appreciated but not required.

Wow, finally an official full ram version of a mattc release

I am an ardent follower of your releases, bordering on religious zealotry. Plus, stock froyo with no Sense baggage. I expect this thread to explode within the next few hours...

as always, many many thanks for your hard work.
