Hi all,

Currently I'm using the Overcome 3.1.0-Kratos on my SGT EURO.

I want to OC/UV my tab. Can I just flash the zip file? I have the standard Overcome kernel.

Pimp My CPU is also a good alternative to OC/UV right?

Hope someone can help me.
[Galaxy Tab  Android Development] OsitKP:
Kidding? Overcome's kernel is OC! But sure you can flash this kernel. They have almost the same functionality. Voltage Control is very popular to OC/UV your processor.
[Galaxy Tab  Android Development] [-Amrish-]:
Well yeah, I thought I needed to use chainfire's apk for ext4. But Overcome is already on ext4 right? Then I only need to flash this kernel via CWM.

Thanks again!
[Galaxy Tab  Android Development] lomniom:
No more news from koxu. Hope everythg is alright in Japan.
[Galaxy Tab  Android Development] OsitKP:
Yeah. It's more than a month already. Hope so too.

It worked on DXJPE and DXJPI

Quadrant Score is 1600 out of the box (after converting to ext4)

after undervolted using Dip7 guidance, OC to 1.2 results 1800 and 1.4 results 2200.

Anybody can get a higher score ? kindly share the configuration (io scheduler and cpu governor).

I noticed that using this kernel, quadrant testing seems to lag a bit during database writing.

And on game inotia3, the sound a bit choppy every some moments.

PS: is koxudaxi sensei on holiday ? its been a while since we saw him around this forum.

back to the thread.

hi, everyone.

sorry... i didn't come to xda for some time

i have got sick on my mind:(i had a lot of drink every day which took me to dream . but, it couldn't clear dark felling on my mind for a few week.

I'm on the sunshine coast in Qld Australia kox. You have a bed and food and warmth here as long as I'm alive and kicking. Its almost summer time here too..

I know the darkness you speak of, and the pain it inflicts on your very soul, but you are on the right track to defeating it my friend but always remember people come and go, things come and go, the one constant through it all is you. Be strong and fair and a good person, as you seem to be, and you will always have more people and things to replace those that are gone. Although no one is ever truly gone mate you can forget sometimes, usually cause your drowning in regret, that we actually help them live on by our actions and the path we take.

Best of luck mate, if ever in Australia please look me up and I will shout you a beer at the very least.

hello everyone!!

i made new function. could you want this?

it is easy led switch which can turn off and turn on led lights by pressing menu button

i just upload a demo video on youtube

http://www.youtube.com/watch?v=TZzhxbDl1jo&sns=em

a introduction for this function:

i want to turn off lights on led buttons.

i often need lights in the dark .but i usually don't need lights for example ,watching movies,playing games,reading books on Kindle app.

how to use it: press menu button(left button) for about 5 seconds
[Galaxy Tab  Android Development] nadiros:
Wow koxudaxi ! great to see you have returned :)

This is a sweet feature for our tabs, totally.

Thanks for your efforts .

Will this be part of a new kernel ? ;p
[Galaxy Tab  Android Development] daniel.weck:
Button Backlight Widget by Aleksandr Beshkenadze works well too.

https://market.android.com/details?id=net.beshkenadze.android.buttonbacklightwidget&hl=en

I would love a way to disable the capacitive buttons completely (and temporarily), they are extremely annoying when watching video, reading, etc. => buttons get pressed inadvertently when rotating the tablet in the hands.

Cheers! Dan
[Galaxy Tab  Android Development] koxudaxi:
sorry couldn't come this area long time

my body and my mental was not good

but, recently i'm fine.

@nadiros

hi,nadiros

i was thinking upload my kernel with the function.

but, i noticed it have a little bug. it is pressing menu button after pressing menu button about 5 seconds.

i will upload a kernel tomorrow because must fix a bug.

@daniel.weck

hi,daniel.weck

thank you for telling me the app

the app is good things. but,i don't like going to home screen;p

i want function that easy and friendly for users

Of course not lol. If the vibrant can do it. The captivate at 1.5 are all stable. Granted its not Samsung but my friends mytouch 4g is stable at 1.8! He runs 1.5 all day long. The only thing it might do it freeze lol then you just know it can't in that speed. But I think 1.6 is easily do-able. If I knew how to compile a kernel Id do it. I only know roms on my nexus.

[Galaxy Tab  Android Development] bendjlee:
Your a machine! thanks just when I decided to run your kernel again. Btw the v1 euro seems to work much cooler for me now. Stuck at around 32-33 degrees

** Update, Flashed the euro_v2 Kernel

with first boot i jumped into CWM and did a quick test to clear davik Cache - works well

Rebooted and no problems encountered so far... will monitor and report back

(For those curious, the Camera has not been addressed yet)
[Galaxy Tab  Android Development] koxudaxi:
you make me happy by your nice reports.

i hadn't used the cwm yet.

it' very cool that it convert rfs to ext4 over auto!!

i think I change kernel source tree for camera work.

later,i would break the wall is called 1.6GHz.
[Galaxy Tab  Android Development] bendjlee:
Yep, just one observation the under-volt settings are not loading on reboot at the moment... My busybox hasn't changed this is at system\bin\busybox.

it works in the original ver and also under v1...

(have deleted busybox and re-installed to no avail...)

>>

I am taking a guess here, that the reason my voltages are not being picked up is because CWM requires its own busybox and you have integrated that busybox into sbin?

Im not too familiar with the interactions between busybox and voltage control but that is my best guess.

Booted into CWM and wiped my cache fine

Reboot fine and Yay my underclock settings have been loaded correctly.

Will let you know if i noticed anything unusual.
[Galaxy Tab  Android Development] bendjlee:
Hey...

I just noticed that my 3G had disappeared with your latest build... will try to confirm by flashing euroV1 to see if i get it back.

Update 1, instead of flashing your earlier kernel i rebooted to check if i still had my baseband / Modem and surely enough that is missing now that i flashed this build (will reflash my modem shortly).

Update 2, reflashed my modem via Odin. Booted fine but baseband is still not present... gonna down-grade to v1

Update 3, I have my 3G back here are my findings:

Euro v1

> Modem working

> NO CWM

> underclocks loaded on boot (voltage control)

Euro v2 (Original)

> Modem working

> CWM

> underclocks NOT loaded on boot (voltage control)

Euro v2 (Current)

> Modem NOT working

> CWM

> underclocks loaded on boot (voltage control)

>> I believe the Modem is still there however it is not being registered, i.e. i was on the latest v2 with no BASEBAND (even after reflashing my modem)

>>>Reflashed Kernel V1, then upon booting into V1 the kernel reckonised my Modem

BTW the modem im using is the P1000XXJMA from Roto's thread

(I am currently running V1 as it has the main things i care about, 3g + underclocks loaded on boot)

I must admit, the battery draw was very high in version 1 (yet I could not see any suspicious activity in the battery statistics), so I will test again with version 2.

Are you kidding? Dip7 made recomendations for his own kernel. What is your goal? To get rid off improper sound or follow dip7 recomendations? As for sound set min freq for example 400MHz. If it helps set freq lower to see if it still is OK. There was written in this thread that changing governor/scheduler also can fix the problem.

i do undervolt based on dip7 recommendation to lower the battery consumption, switching to powersafe (i think its the name, forgot) did fix the sound but the performance is not as good as on demand.

i ll try other governor/scheduler to get the best of it as soon as i got back to dxjpi. Any governor/scheduler recommendation ?
[Galaxy Tab  Android Development] OsitKP:
Search the thread, I don't remember exactly. As for UV, you can try it in the end. Because cracking (or what) sound means there is not enough CPU perfomance, and UV makes the situation even worse.

If my memory doesn't fail me you should try "conservative" governor.

sorry late, recently i'm very busy. it's difficult to get time to develop a kernel .

btw i just build test kernel for you which have "batt_current"

but, i feel it's strange value. i can watch the value in Elixir 2.2

it's very long range like -800 ~ 900 .

i can't understand it :confused:

i pull this value from "current mA"

you can see the value in # dmesg

Soo, first, thanks for this new one with my wishes and second, you are right, those values are very strange.

In my HD2 i have -3/-5 in stand-by and -240 ma in use, so i suppose that here we have something wrong with battery driver.

Unfortunately i'm not a kernel man and i can't say where and what is wrong, sorry.

Lastly, i suggest you to use "Current Widget" from market for have a better check of battery usage.
