Root [Virgin Mobile/Sprint] Overclock kernel and V6

R

I have built an overclocked kernel. CPU to 1.7 ghz and GPU to 450 mhz.

I have been running it for 3 months without issue.

I also have a V6 software update that does not adjust the radio, or the kernel, just the software.

You need root for the kernel and custom recovery for the update.

Is anyone interested in this?

I have a cm10 build as well, but it has issues.

Here are some screenshots of Antutu benchmark.

Ok, here are the files:

WARNING, APPLYING THESE CAN DESTROY YOUR PHONE. I AM NOT RESPONSIBLE. IF YOU APPLY THESE YOU ARE A HACKER AND YOU ARE DOING SO AT YOUR OWN RISK !!!!


Both a non-lokified and a loki-fied image are provided. Your aboot may be different than mine, so you might need to re-loki the raw boot image.

loki-fied boot image

YOU MUST DISABLE THERMAL MANAGEMENT, OTHERWISE THE OVERCLOCK WILL BE DISABLED. YOU NEED TO LINK /system/etc/thermald-8930-empty.conf to /system/etc/thermald-8930.conf

YOU CAN ALSO DISABLE THERMAL MANAGEMENT via the "hidden LG menu".

Or you can post this file to /system/etc which will retain the thermal management capabilities but support the overclock in the normal temp range.

Finally, here is a VM V6 software update that does not upgrade the radio, or the recovery. I am not sure how this will affect future updates.

INSTRUCTIONS

To install the kernel, you need must use a loki version. Then, copy the file to the external sd card using adb. Then use a ROOT adb shell to the device and enter

cd /storage/external_SD

dd of=ls720.original.img if=/dev/block/platform/msm_sdcc.1/by-name/boot

to save a copy of the existing boot image, and then the following to install the overclocked boot image

dd if=ls720.overclockV2.lok of=/dev/block/platform/msm_sdcc.1/by-name/boot

You must have CWM installed, so if you have problems, you can reinstall the old boot image. If you do not understand the above, then DO NOT ATTEMPT THIS !

To restore the original version, use

dd if=ls720.original.img of=/dev/block/platform/msm_sdcc.1/by-name/boot

Here is an updated overclock kernel,which limits the initial cpu frequency to the stock 1.2 in case there are problems. Also, it enables a multicore cpu scheduler which should provided much better battery life for occasional use.

why not includ the kernel with the cm10 rom and work with xclusive to get a good working rom.

Because the stock rom isn't bad with the over clocked kernel and CM10 is a lot of work. I also have a one click wifi tether app that works well with the stock rom.
 
Very interested. I've been following the development on this phone for awhile. Would love to see a working CM or AOSP 'pure android' experience on this excellent device, and I'm excited to know that O/C is working and has been working for you.

How soon can we see links?

which ap actually works as a wifi tether on it's own, I've only been able to get a hotspot (without any security or changing the name by using two apps together)

I installed the kernel and that file you posted, and so far haven't noticed a difference in performance when overclocking :confused: my benchmark score only went up by like 800 points on antutu across all the frequencies (as compared to stock speeds)

You need to install a cpu monitor. It should be able to track the cpu frequency of both cores.

Also, did you install SetCPU or a similar program to allow you to set the governor and cpu frequency?
 
One other thing I forgot to mention, this boot image moves the dalvik cache to the cache partition which frees up 100's of mb on the internal storage.
 
Robaho, can you and xclusive work together to create a CM Rom that has overclock as well as the app2sd pre-installed? I don't like the stock ROM (I think alot of us agree on that), too many issues and it just gets tiring. I want to have a decent working phone. Any help will be greatly appreciated.
