[MOD]viperMOD for AOSP and Sense Kernels - v3 beta RC2.4 |Updated 6.14.11|

-viperboy- · May 30, 2011

Hey everyone, welcome to viperMOD for the EVO, Incredible, Nexus One, Desire GSM, Thunderbolt, Nexus S, Nexus S 4G, Desire HD, and Inspire 4G. Many people are having great success with this mod and I hope you enjoy my work

I would like to turn this into an app! If someone would like to help out that has Java knowledge, please contact me!

What does this do?
Kernel developers make their kernels to be "universal". By universal, they want the kernel to work on as many phones as possible so they may only mildly undervolt. However, some phones can handle a more aggressive undervolt. Some can't. viperMOD allows you to undervolt to your choosing for better battery life or allow you to overvolt to make your phone more stable.

How do I run this?
Once you flash the .zip go into your Terminal app (I use Android Terminal Emulator set to 10pt font) and type:

su
vipermod

I really only use Terminal for my mod and there is something really cool you can do with Android Terminal Emulator (and maybe others). Menu > Preferences > Initial Command > Press Enter and type su > Press Enter again and type vipermod

Every time you start Terminal now, it will open right into viperMOD. You can quickly exit by pressing Enter if you need to use Terminal for something else

It shows that voltages can be lowered with a script. He may be using a different type of vdd interface than most kernels. If you want to post in his thread to ask, that would be helpful. I don't really have time to read the whole thread to see if it might be posted in there.

I could take a look at the folder the file I need to modify is usually in. Can you .zip me your /sys/devices/system/cpu/cpu0/cpufreq folder? Or just do an ls on it and copy me the output from that.

Also, you can try Leedroid kernel if you want to use this right away.

No problem. Thanks for testing and confirming it works

Right now my kernel uses the vdd table in acpuclock7x30.c to overclock and set voltages, but haven't incorporated the 'sys-interface' yet, so there is no vdd file in /system/devices/system/CPU......./cpufreq/vdd...( which will be added in next version of the kernel to make this work properly). Its still adjustable with an init script, just can't see it like you should be able to.
Leedroids kernel will probably not work since his is a sense rom, mines aosp. (just the zimage will probably boot, but there will likely be problems, the whole boot.img will deff cause problems)
So, its not vipermods fault, I need to get around to updating my kernel again.
Edit- I quoted viperboy, but this is more directed to trell

Yeah I was going to say about leedroids kernel, sense kernel on an aosp Rom doesn't seem like a good idea

This is something that I'm having a hard time pinning down. I don't get this error on my EVO but someone in the Desire forums, I believe, got this error too. I'm wondering if it's ROM related since other people using Leedroid have it working. I will see what I can do, crap like this is just hard to sort out without the phone sometimes.

killersloth · May 30, 2011

Any log I can pull for you? I'm away from my laptop though.
I'll look at the script and find where it pulls that from and try to work it out. I'll let you know.

You don't get into the script at all, right? Unfortunately, there would be no log you could give me. 1stgensnapdragon is a function setup in my script, however, that has nothing to do with the Desire HD/Inspire 4G since you guys have a 2nd-gen Snapdragon and I have a function for that.

If you find anything, please let me know!

I'm not too sure but I'm thinking your script detects my processor from build.prop, this is the line from mine:
ro.board.platform=msm7x30

It does pull that line from build.prop but it knows it's a 2nd-gen Snapdragon and that shouldn't make a difference.

OP updated!

HTCOmega · May 31, 2011

So I updated my copy of VMod script and BusyBox (thank you much, btw. Speedy updates are a joy...I guess maybe I'm just impatient at times lol) via ES Explorer then chmod 0777 for both w/ emulator and it still doesn't work. Both updates seem to have taken and now I get errors on lines 9 and 399, I believe. It's the "uname" and "1gen" errors from earlier. "Tr" and "cut" don't throw up errors anymore so that's at least some improvement lol

Need anything more from me to help out?
