Nexus 7, ParanoidAndroid and franco.Kernel

By | January 2, 2013

So I completely wiped my Nexus 7 today and installed stock 4.2.1, then installed a custom ROM and kernel and seems to be running well so far. I normally use CyanogenMod on my Android devices but decided to make a change.

I have also undervolted the CPU and added some extra tweaks, and as with my previous posts about my Galaxy S2 I thought I would add a post for my reference.

Device: Nexus 7 (16GB – WiFi)
ROM: ParanoidAndroid 2.99 Beta 9
Kernel: franco.Kernel r37
Mods: Beats+Xlouder V3Beta2
Apps: Trickster MOD and Stability Test

I used Tricker MOD to change some settings and undervolt by -100mV and then ran the following Stability Test’s.

  • Classic Stability Test for 30 minutes.
  • CPU+GPU Stability Test for 20 minutes.
  • Scaling Stability Test for 20 minutes. (100Mhz – 1000Mhz @ 2 minutes per frequency)

There was no freezes or reboots and CPU sat around 36c the whole time.

Here are my settings for Trickster MOD, now remember every device is different so what is stable for me may not be stable for you.
