[Q] Undervolt - Desire Q&A, Help & Troubleshooting

Can anyone help me find rom that can do undervolting? I can't find any rom which has undervolting gui.

You dont need a custom rom you need a custom kernel that support undervolt

You need kernel supporting UV and this: https://play.google.com/store/apps/details?id=com.incredicontrol&hl=en

Ok, and which kernel is that ? How can I find that?

For example: http://forum.xda-developers.com/showthread.php?t=883598

Thanks, I'll try out now .

[Q] Overclock ISSUE

I trying to overclock but the program only appears 1024Mhz not until 1500 or 1.9Ghz :S
I already flashed kernel...
use setcpu or nofrill to set it,it should be 1.6 2.0 max if you're using doomkernel..btw which app you use?
Sent from my LT18i
NoFrill, but it say only 1024mhz
if 1024 it is stock kernel for arc,do confirm the kernel you flash can oc t 0 2.0?

Im using MIUI Kernel, 2.6
Because use MIUI Version of ROM
Will try DOOMLORD KERNEL MIUI 2.0 ty.
miui only 1024,so you only can oc to that value..
Sent from my LT18i
Done with MIUI DOOMLORD KERNEL
Ty.
im suggest jason's kernel for miui,good battery saver and great performance,dont need to oc(my opinion),try v6supercharger,so you can have great battery life plus great performance,just an advice

[project]kernel-galaxy y

I HAD ONCE A GALAXY Y(sold it). ALL ROMS ARE STILL HERE IN ME EXCEPT THE NEW ONES OF COURSE.
OK. i had now a SHW-M130k. I had Tegrak Overclock from the Market and happen to share it with my classmate. Said that it worked =="
We have same kernel
2.3.6.35.7
PLS VERIFY IT.
IM STARTING TO MAKE A KERNEL FOR THIS DEVICE AS PROMISED TO MY FELLOW SGY-MATES thanks in advance but pls send me feedbacks regarding this
link:
https://market.android.com/details?id=com.tegrak.overclock
you will see it as compatible.
Bro how will you test ur kernel if u dont have the device?
when i click on something in tegrak overclock it is saying "Your device or kernel is not available."
My Kernel 2.6.35.7
not work
Tegrak Overclock not work last weak i tried this app not work. for Overclockwe need custom kernel. i hear Repencis ROM have custom kernel so anyone tried to overclock this rom?

the dev of Repenics rom is saying that it doesn't have a custom kernel.. i guess the ones who were saying that it has a custom kernel were wrong..
cool.. keep up the good work
off topic: what phone did you buy ?
Crap. Wait ill see in it more but im sure we had same kernel

[Kernel][How to] Flashing a kernel

Hi all,
I am here to share another [How to] on flashing a kernel. There are quite a number of kernel available in our forum such as Cow Kernel, stock kernel, etc. They have different capability such as UV, OC and equipped with different governors too.
This tutorial will teach u how to flash a kernel easily.
HOW?
To flash a new kernel,
via adb shell
1) Download the kernel
It is as easy as just copy the boot.img from the ROM equipped with kernel u want.
2) Download the Wifi module dhd.ko
Copy dhd.ko from the ROM with kernel u want, it is under /system/etc/wifi
(without getting this, ur WIFI will not work)
3) Copy both files into your phone by using adb shell or simply copy them over from ur PC.
Code:
adb push boot.img /sdcard/download/
adb push dhd.ko /sdcard/download/
4) Flash to your phone
Code:
adb shell
su
dd if=/sdcard/download/boot.img of=/dev/block/mmcblk0p8
5) Copy dhd.ko to /system/etc/wifi/ via Root Explorer.
Reboot. DONE~
via CWM
1) Download the kernel u want from attachments.
2) Boot into recovery mode by pressing power+select+volume up bottons
3) Flash the zip and then Reboot
Just a personal experience, the XXLM8 and DXLM3 kernel give us better visual performance and make ur Temple Run smoother.
Same advice, do at ur own risk. Remember to do a nandroid backup beforehand.
Thanks bro...
How about battery life? Which one is better, Cow's or XXLM8 kernel?
in my opinion Cow kernel is the most performant, best benchmark scores and best ram management. XXLM8 has a better battery life and a good durability.
I personally prefer the Cow one couse of the performance.
In my opinion cow rom are best with benchmark point which is very high but not in real app performance..
I tested temple run on both rom, and xxlm8 just slightly faster than cow
And also battery life is longer with xxlm8..

Terifish is correct. Cow kernel has better benchmark score but that is not true in real application. Overclocking doesn't improve the performance for gaming because that is actually related to GPU and ram management.
XXLM8 has been proven to have better gaming performance. U can personally experience it when playing Temple Run.

Theoretically, cow's kernel should give better battery life as it is undervolted.

U need to use adb shell for flashing it. Not sure whether a flashable zip can be created for this. Any expert can help on this?

And this one too cuz when I using Cow rom a while ago , I put on standby it consume 1% for 4 hours , under normal use (wifi all day long, some call, sms, email , gaming ) still can hold more than 50 hours . . but change to others roms due to FC essue..

LOL~ Seems like XXLM8 is really a good kernel for our SGW at this moment.

really agree with you..
i'm very satisfied with my SGW battery performance with XXLM8
Which governor should be adjusted to save power and still have a good performance on XXLM8?

I suggest using CPU profile scheduler such as SetCPU. Use ondemand for normal usage and set powersave for screen off.

I wonder that too... I'm not familiar with adb yet... CWM rules when it comes down to being "easy", hence safe, if you know what I mean...
I'm really excited to flash this kernel now...
I noticed that inside the nandroid backup folder there is a "boot.img", so, why can't we just exchange it by the one from XXLM8 and just restore it to have it flashed? I didn't do it yet because there is no turning back after messing with the boot.img...
I read this thread, but I'm still not confident enough to do it...
Does anyone know if my theory stands?

No. U can't do that. If u replace the boot.img in a ROM zip, there will be md5 checksum mismatch error. U need to resign the zip again.
okay, if you want to try different kernels without using adb, attached are update zip for Cow kernel and XXLM8 kernel...
just put it on your sdcard, and install it through CWM recovery...
enjoy...
Hello to all, i want to flash the xxlm8 zip using cwm. But as mentioned do i still need to flash the wifi module? or is it already included in the zip file? not comfortable with adb as i might mess things up.

the specific wifi module for each kernel is already included in each update zip file... i tested both of the zip files, and i can switch kernel whenever i want...

Which is the best kernel for the Stock Rom for Overclock

Hello.
Can you help me please?
Which is the best Kernel to overclock my wildfire using the stock rom. (Phone is already rooted). I'm seeing that there are some kernel that present problems with wifi and GPS, anyone know's which doesn't give this problems?
If I don't like the kernel, is there any way to get back to the stock kernel?
Thanks a lot in advance!
Go to rempuzzle thread in the dev section and read the first post. You will find rempuzzle kernal (overclockable) and the stock one both as flashable zips.

[Q] tun.ko

sorry.. im just wanna ask.. is that gio have tun.ko? stock rom? cm7 nightly? im confused im install droid vpn.. but.. no tun.ko
Custom kernel's and custom ROMs have it.
Sent from my GT-S5660 using Tapatalk 2
1. Support of tun.ko are in Custom Kernels
2. From where u can get one? U cant get one since its a kernel module which will be builded when u apply it in the device manifest of the compiler ^^
is that cm7.2 from marcin have it?? which rom have it?? which kernel have??
