Okay & thanks
[Galaxy S II Original Android Development] vnvman:
Just raise the maximum voltage: my phone is unstable when using the default voltage, while 1450mv @1600mhz is totally fine. Anyway, why would you oc that much lol, this phone is buttery smooth @500mhz already :rolleyes:

@spaxx24: what is your lowest voltage? Usually sod is caused by a too low voltage for the 100/200 mhz step: my device for example it's unable to go lower than 850mv without getting it...you know, some chipsets are more lucky than others i guess ;)
[Galaxy S II Original Android Development] shummo:
update?

Will there any new release? Because i want to flash beta8, but if you are ready wtih beta9 or rc:D i will wait for it.:D

[Galaxy S II Original Android Development] Lennyuk:
well a file is added to /data/.siyah/ when it is done so you can roughly work it out from that.

edit: ignore this, superseded by the kernel dev above
[Galaxy S II Original Android Development] spaxx24:
I got both 100mhz and 200mhz @800mV. But have had this for 2 with difenrent versions of this kernel, without SOD.
[Galaxy S II Original Android Development] RavenAlias:
Hi boys!

A curiosity here!

Undervolting is a dangerous procedure in the long time?

I use these values:

100Mhz-------------825mv

200Mhz-------------850mv

500Mhz-------------875mv

500Mhz-------------975mv

1000Mhz-----------1075mv

1200Mhz-----------1175mv

1400Mhz-----------1250mv

1600Mhz-----------1400mv

I tested my sg2 and it is stable, i don't have any fc o reboot. I tested this configuration with hd games (very heavy!) and thought the stress test of setcpu.

Is there a risk keeping in long time this configuration?

thx a lot!
[Galaxy S II Original Android Development] TheFluffyOne:
Clock time drift issue does now appear to be fixed. My clock has not drifted more than about a second in the last twelve hours or so, compared to 30 seconds per hour previously. The drift value fluctuates a little between half a second and a second, so that could just be down to the OS or ClockSync itself.

Thanks!
[Galaxy S II Original Android Development] Bene2k11:
Nope. Else than overclocking in combination with higher voltages, undervolting shouldn't damage anything. Not even concerning a long time. I could imagine that it even raises the lifetime a bit.

You can get for free from the market,

BTW did u tried using it
[Galaxy S II Original Android Development] Bene2k11:
Unfotunately the free version is quit limited. :( You can't set 100Mhz to 800mV for example...

Which values do you use?
[Galaxy S II Original Android Development] AndroidGX:
Yeah but on SetCPU you even can't modify at least -25mV without buying the full app, so it's better than nothing. :)
[Galaxy S II Original Android Development] Lennyuk:
I thought with setcpu he provides a copy of the full app here on xda for free, or has he stopped?
[Galaxy S II Original Android Development] AndroidGX:
You are right (cf original SetCPU thread) :

strange issue

now this is randomly happening to me. sometimes when i look into my app screen i see that my apps are uninstalled and see a square grayish icon with an android and an SD card on it. when i click on them it says application not installed on your phone. don't know whether its a Rom or kernel or even launcher related issue. can somebody please help.:eek:
[Galaxy S II Original Android Development] vnvman:
Just try restarting the launcher.
[Galaxy S II Original Android Development] -ph-:
Use ZDbox and see if the app its located in the sd. you probably need to move to the phone again.

[Galaxy S II Original Android Development] kwerdenker:
I honestly have no idea. It's probably a gathering bin for everything not falling in the other two categories, though I can't think of anything that isn't either USB or AC from what I remeber how this stuff is identified in hardware ^^

[Galaxy S II Original Android Development] gokhanmoral:
MISC is the charger type which has no connection on the data pins.

genuine chargers are detected as AC, others (such as cheap car chargers) are detected as MISC.

that is why you lose charge while using navigation (gps on) when connected to a car charger.

the default MISC value was 450. I have increased it to 550.

the other changes are up to you...

I always want to keep default settings stock (or at least close enough to stock).
[Galaxy S II Original Android Development] kwerdenker:
Ah, ok. Always thought those would just be considered USB. Thanks for clearing that up :)
[Galaxy S II Original Android Development] holyshit1:
I want to clock gpu to 400 mhz and i have question again :D, wich is stable voltage for that clock? It is only for one benchmark.
[Galaxy S II Original Android Development] gokhanmoral:
by the way, the easiest way to fake a cheap charger as a genuine is to short the data pins :)

or buy a usb m-f connector, short the data pins and use it in between the charger and the phone.

or just echo an appropriate value to charger-current device :)
[Galaxy S II Original Android Development] gokhanmoral:
use 1200. it will not burn your device :)
[Galaxy S II Original Android Development] holyshit1:

[Galaxy S II Original Android Development] kwerdenker:
Sorry to be the partypooper, but I just had a wakeup-lock with the beta1 version. Will have to flash beta2 and then keep an eye on that, but I think this will have to wait till tomorrow.

Oh and also: maybe you could re-activate /proc/kmsg as long as we are working with betas so we can take some logs to check for issues?

[Galaxy S II Original Android Development] hausmanis:
This Kernel was made to be batteryfriendly as prio 1 right ? so much bable about test scores and stuff here, or am i mistaken ?

Anyways i now installed beta 2 to Touch-Xpower+ would love if you could do the same optimization to that one as the one bundled with the rom, felt great to have a custom made kernel for the rom.
[Galaxy S II Original Android Development] brack11:
So, if I understood properly the default governor in this kernel is smartass? That means that without any setcpu my idle freq would be 100 mhz? Correct me if I'm wrong. I want to try to not use any uv/oc or setcpu apps and wish to get the best battery.

I'm using stock with 100MHz and it is stable for me but not for everyone.

[Galaxy S II Original Android Development] gokhanmoral:
raise it back :) these values are so low...

your device may not be able to change frequency at that voltage.

I thought you were the one with low UV values.. so the news is not so bad :P
[Galaxy S II Original Android Development] kwerdenker:
No, default ist ondemand with 200MHz as scaling_min.

If you want to change this without apps, have a look at my init-scripts in this post.

If you still use original samsung charger you shoud leave it at 650 mA or you could max it to 700 mA, otherwise you could damage your charger, because it can only delivers 700 mA max safely.

If you're using a HTC charger for example, i think it can go all the way up to 1000 mA (please correct me if i'm wrong, don't have one right here to check).

Hi!

Nice to see a kernel that actually has fixed the Android OS bug, good work!! Unfortunately I have seen a bug that prevents the device from entering deep sleep. For some reason the GpsLocationProvider keeps a wake lock so the device stays active all the time. I'm currently running 2.0 beta 8, but the error was present at 1.8 and 2.0 beta 7 as well. I have not seen the error on earlier versions.

I'm currently running Batista FoxHound ed 2.2, but the error has been present on other builds as well.

It may be nothing more than co-incidence, but I had the exact same problem, which started when I installed Google+, and ended when I uninstalled it a few days later?
[Galaxy S II Original Android Development] Muchoaliento:
Yep, I did.

Same issues over here, cannot turn off wifi through action bar icon nor settings, here screen goes black.

Have to reboot, phone reboots but with wifi on (and with wifi icon in an "intermidiate green" colour. By this I mean that upon press for deactivating wifi, it stays in a dark green colour and is not "selectable" anymore)

Using Villainrom 3.0 with Siyah 1.8 final. Will test with 2.0b8 and report back.

Found a workaround: have to start and stop bluetooth radio. When BT turns off (icon goes from "intermidiate green" to white, same happens to wifi.

EDIT: just installed 2.0 b8 and still cannot reenable wifi upon turn off, toggle switch stays in "dark green" colour and is not selectable, bluetooth workaround works sometimes.
