Have yet to try this but I am wondering the same thing?
[T-Mobile, Samsung Galaxy SIII] krntehknik303:
There are.. I just didn't read the OP all the way. He recommends us using system tuner.
[T-Mobile, Samsung Galaxy SIII] frewys:
Will try. Looks like a good dev. So looking forward to trying the kernel. UV is why. Thanks.

[T-Mobile, Samsung Galaxy SIII] sbell7105:
Dang I knew I was wrong I couldn't UV with any app then I remembered that I flashed the latest trinity kernel. No wonder I couldn't UV I was running a different kernel (face Palm). I just remember from the t989 that we couldn't UV till source was out. Sorry for the ignorance love the 15u btw going back to that tonight way better battery life.

Are there any plans of getting a 2.1 oc on this kernel?
[T-Mobile, Samsung Galaxy SIII] calvin35:
Just wanted to say that I have tried all the kernels for the at&t s3 and this one is the quickest so far. It may not have the top end speed of the others but it is the most responsive. Battery life is also very good. Great job.
[T-Mobile, Samsung Galaxy SIII] kpizzle:
Wish there was one that worked with a stock rooted ROM :( I loved your work on my g2x.
[T-Mobile, Samsung Galaxy SIII] faux123:
go knock on ATT/Tmobile/Samsung for withholding new kernel source for their latest STOCK ROM.
[T-Mobile, Samsung Galaxy SIII] mr_psycho:
Actually, they did!! :good:

Update1 source is now available. In fact, all that's essentially needed from the Update1 source is the updated BCMDHD driver. That alone should fix the WiFi flaps and frozen lockscreen.

You might need to wipe dalvik cache and fix permissions. If that doesn't work. Just do a full wipe.
[T-Mobile, Samsung Galaxy SIII] sbell7105:
Not that long did you wipe cache and dalvik cache.? What rom are you running and what kernel version are you using?
[T-Mobile, Samsung Galaxy SIII] mike216:
Hi guys and Faux, I have had a horrible experience trying to run anything but stock kernel. I'm on PA a cyanogen based rom. Is the current kernel booting for you guys? I'm very hesitant after what I went through the yesterday. Thanks

[T-Mobile, Samsung Galaxy SIII] schwiing:
I don't see 17m or 17u released on the OP. Where did you see it?
[T-Mobile, Samsung Galaxy SIII] sbell7105:
http://faux.androidro.ms op doesn't really get updates you have to check on Twitter or his site. Don't worry bro someday your Google fu will improve :).
[T-Mobile, Samsung Galaxy SIII] krntehknik303:
What are your thoughts on the newest release? The one called 09/15/12
[T-Mobile, Samsung Galaxy SIII] Nshih422:
Hey Faux, Really love your kernels. I was wondering if there is any chance you can enable 2wcr (2 way call recording) on this for CM10? I know you're really busy but just wanted to make the request and maybe you can one day fulfill it. I would really love it. I have been trying to get call recording to work and have not been successful.

Thanks in advance.
[T-Mobile, Samsung Galaxy SIII] sbell7105:
So far seems way better than 17u did.
[T-Mobile, Samsung Galaxy SIII] qwahchees:
Does this Kernel automatically OC to 480mhz for the GPU? If it doesn't, how would I apply the overclock?
[T-Mobile, Samsung Galaxy SIII] krntehknik303:
I would have to agree. So far I'm at 58% with a little over 16 hours.
[T-Mobile, Samsung Galaxy SIII] qais9:
Not sure if these are kernel issues, but when running the 9/15 on aokp build 2 crt is dead and call volume stuck on max.
[T-Mobile, Samsung Galaxy SIII] sbell7105:
Weird no issue here running same combo. You could try fixing permissions.
[T-Mobile, Samsung Galaxy SIII] gr4p3s:
What's the difference between 17u and 17m? What do the letters signify?
[T-Mobile, Samsung Galaxy SIII] krntehknik303:
17u allows you to over clock up to 1.8 and 17m allows you to over clock up to 1.6. Depending on the phone 17m is more stable then 17u. If you actually search through the forum and read the OP I'm sure you will find your answer.
[T-Mobile, Samsung Galaxy SIII] sbell7105:
Yeah go back a couple of pages it's been discussed a lot and in the op. Btw 17 is not the newest one
[T-Mobile, Samsung Galaxy SIII] qais9:
I'm not sure what the issue was, did a fresh install and everything good now :thumbup:
[T-Mobile, Samsung Galaxy SIII] faux123:
CM nightlies can now be found here:

d2tmo/att kernel cyanogenmod Mainline (OC'ed up to 1.62 GHz, should be 100% stable) m-version

d2tmo/att kernel cyanogenmod Ultimate (OC'ed up to 1.84 GHz, should be stable with most phones) u-version

DUE TO RAPID CM10 / JELLYBEAN development, it is HARD TO KEEP UPDATING the thread: So a special folder was created for CM_Nightlies

http://faux.androidro.ms/CM_Nightly/ (Both U and M version can be found here and the version is based on DATE from this point on forward!)
[T-Mobile, Samsung Galaxy SIII] :
These well get updated as often as nightlies?
[T-Mobile, Samsung Galaxy SIII] faux123:
whenever I have time and/or CM updated their kernalz ;)

I was just about to ask what happened to the 09/15 kernel. Lol. Didn't know you made a separate page. Thanks faux!!!
[T-Mobile, Samsung Galaxy SIII] da-pharoah:
Hola Faux! so Hell asked me to have you look at our new rom and try to get the kernel sorted! Por favor, it bootloops with our new release and Hellfire Roms isnt Hellfire Roms without your kernel!!!! :( my sig has the link for the Hellfire Jelly cm10 rom. Please helpout!! We wish to still use your awesome Kernel!!!
[T-Mobile, Samsung Galaxy SIII] faux123:
It works fine with latest cm nightly. Cm team moves fast with tons of updates and are often not backwards compatible. So you'll need to match the kernel with the latest cm commits.
[T-Mobile, Samsung Galaxy SIII] da-pharoah:
hmm ok we shall have to check it out then...

[T-Mobile, Samsung Galaxy SIII] Ker~Man:
Sorry for the noob-ish question, but does the 9/24 cm nightly work with the latest AOKP build 3 or should i use the direct link(s) below that in the OP? Thanks!
[T-Mobile, Samsung Galaxy SIII] Diekrupt:
Wow using this with cna my gs3 is smoking fast. One request is ktoonz had the cool option to adjust vibration intensity, is there a way to lower vib intensity with this bad boy?

[T-Mobile, Samsung Galaxy SIII] faux123:
new nightly is out!
[T-Mobile, Samsung Galaxy SIII] calvin35:
I just discovered your kernel and absolutely love it. I am currently running your 9/25 kernel with the 9/25 CM10 nightly(very fast and very smooth)and was wondering if the 9/26 kernel would work on 9/25 or if it is meant for the 9/26 nightly?

Edit: Never mind. I think I already have the new one.
[T-Mobile, Samsung Galaxy SIII] Ker~Man:

hi faux, I'm trying to rebuild a kernel for CM10 but my attempt is failing and putting me in a bootloop. So I'm trying to reach out to a few people who have successfully built their own kernel and packaged it for help. I am able to rebuild it without a problem, but installing it seems to put me in a bootloop.

[T-Mobile, Samsung Galaxy SIII] sarni84:
I can almost guarantee your phone don't like the -100 across the board. When u start getting into the higher clocks u can't UV so much. It is causing instability. Some phones don't like this and yours is prolly one of them

After almost 2 hours flickering didn't leave :/ I check tomorrow maybe I'll full wipe and flags cm and the kernel, if issue still present kt kernel here I come lol, anyone that wants on kt, how's battery life for you guys?

[T-Mobile, Samsung Galaxy SIII] neyenlives:
i just read every page of this thread, every post, and not one single person offers what voltages they are running at each frequency. Using System Tuner it shows every frequency using 1150mV except 1.62Ghz which is set to 1200mV. This is really bad and needs to be adjusted for lower operating temp and improved battery life.

Can we get some info on what stock voltage settings are for reference?

**so i found this post and used it for reference

http://xdaforums.com/showpost.php?p=30896579&postcount=1222

and from that I came up with this using the System Tuner app

Mhz Frequency

0 800mV

384 875mV

432 900mV

486 900mV

540 925mV

594 937.5mV

648 937.5mV

702 937.5mV

756 975mV

810 1025mV

864 1050mV

918 1075mV

972 1100mV

1130 1100mV

1180 1120.5mV

1290 1137.5mV

1350 1150mV

1400 1150mV

1450 1150mV

1510 1150mV

1620 1175mV

Now every device is different so this may crash your system. I have been using it for an hour or so so not much, ran Temple Run game for a few minutes, ran the Metal and HTML5 Vellamo benchmarks, no problems, scored as high or higher than the Intl GSIII .....played around, so far no hangs or crashes on the 10-3 Official CM10 using this kernel (Mainline version of 10-3 kernel btw)

[Vibrant Q&A, Help & Troubleshooting] JustTheHustle:
Well apparently, after flashing the latest AOKP for my phone, it keeps on rebooting itself at random time, and at other times, doesent boot at all. When I put it on charge, it shows the battery for a few seconds. I am unable to get in to recovery as it basically reboots there as well. In Download mode, I restored stock 2.1 FW and bootloaders carefully, but nothing, its still giving me an issue? Any advice, might just move on to the Galaxy Nexus:confused:
[Vibrant Q&A, Help & Troubleshooting] Woody:
Did you do any flagrant battery pulls lately? Maybe check the contacts or that the battery fits snugly. Doubt that flashing caused it, but maybe something with the kernel power source.

[Galaxy S III Q&A, (US Carriers)] tcb4:
When I first got my phone and put a case on it just browsing the web got it up to 59 degrees Celsius or 138.2 degrees Fahrenheit. I looked at some other threads and people said that 60 degrees Celsius is nothing for a CPU, but then other people are saying that it can fry the CPU. Now that I have restarted the device the phone stay much much cooler. I just want to know what a dangerous temp is? Some people say that damage can occur around 60-80 degrees and other people say they have had their cpus hit 90-100 degrees Celsius.
[Galaxy S III Q&A, (US Carriers)] id_twin:
I'm assuming you mean Fahrenheit. I would say 90 - 100 degree is normal-high when running games or heavy applications. Really when web browsing/idle 60 - 80 would seem like the average.

Edit: I see your calculations now. No, 138 browsing the web is not normal - And beings that the boiling point of water is 100 degree Celcius, that certainly is not acceptable.
[Galaxy S III Q&A, (US Carriers)] tcb4:
nope celcius. mine idles at about 93 degrees Fahrenheit.

Edit: Ok, thats what I thought. It didn't stay there long and a restart seems to have corrected things. Do you think that could have damaged it? I just imagine it was a app hogging resources, maybe just chrome being buggy.

with that said the thermal shutdown point for the nexus is 110 degrees celcius, however it starts throttling the clock speed at 60 degrees. some people have claimed to have got it there.

hello guys.

well i have a very big problem here.

i got 3 weeks ago an xperia S white.

i updated and rooted my device, was on 2.3.4 now 4.0.4 bootloader locked and rooted.. Yeah!!!!

everything was cool and excellent.

but here comes my stupid nephew and i dont know what he did.. but the device wont turn on and wont charge the battery .

i was thinking ok ok ok, with flashtool and everything cool...

but heres the problem, the device wont start in flashmode

i set flashtool and all, but when you need to plug the device pressing the vol - the flashtool wont recognize the device, so it does nothing...

i have charged the device for almost 6 hrs and nothing,

turn on with Vol +.... nothing as well....

so, i think its bricked but how??

so heres my question is there any way to "unbrick" this device???

thanks for any answer.

thanks.

nope the battery have 75 % test this battery in another device.

omg im lost... :crying:

btw he said something, he told me he saw yellow letters.....

and the only thing i can think is clockwork mod...

what the **** he was doing there i dont know....

if he deleted something, can be fixed???
[Sony Xperia P, U, Sola, Go] gm007:
Well ask him what he was doing maybe he flashed a firmware for another phone.
[Sony Xperia P, U, Sola, Go] lito003:
I had the same Problem, after a Kernel flash.

Xperia S seems to be dead, Power + Vol. UP didnt worked, it just vibrated once.

But now its working again. What i did:

Connected it via USB, hold the Power + Vol. UP button until it vibrated 3 times and than released the Power button but kept the Vol. UP Pressed.

Now it should be in Fastboot mode again. :D

Hope it will work for you. :fingers-crossed:
[Sony Xperia P, U, Sola, Go] corum3:
volume + and volume -

Try pressing both vol+ and vol- while holding the power button for about 10 seconds, you should get 1st one vibration and then 3 vibrations. worked for me when I thought I had bricked my S.
