Folks,
I have searched this site as well as the net and I keep getting links to install custom kernels, not how to set undervolting. I have the overcome kernel installed. Can someone give me some guidance?
http://forum.xda-developers.com/showthread.php?p=11850429#post11850429
This is the thread I followed. It also has OC instructions, but I am sure you can just use the UV setting if you like.
The UV app is called voltage control. It's free and in the market.
Also, I have the same kernel/rom as you, and I followed all the settings in that thread (OC/UV). My tab is working nicely those settings.
Hi all,
I tried finding a corresponding thread, but couldn't.
Briefly, after flashing Burstlam's ICS remix, I overclocked the CPU to 806, keeping the smartassv2 gouvernor.
It was stable for half a day, then my screen flashed twice with pink sqares and some other mess - restart - and since then it behaves like a PC with missing graphics drivers.
Have I burnt some kind of coprocessor? Cuz no matter what I do(full wipe - reflash, left phone off over night with battery extracted, etc.), scrolling is now choppy as hell. At any frequency .
Pls advise if there is any chance to "fix" this.
Many THX in advance,
Robin
PS.: Maybe this could at least serve as a warning for others, do not risk with 806Mhz!!
806MHz is a risky overclock and should be reached in steps of lower frequencies. Userspace governor is usually used when overclock speeds of 806 are achieved. Best thing for you to do would be to 'Try' to make it stock and go for warranty. Looks like there's a serious issue with the phone.

Yea.... Restore stock and give your mobile to service station!
Thanks folks
Hi,
Thanks for the swift responses both. I'll give it a shot.
Any special hint as to how to hide the SU bin? Presumingly I'll just restore my initial backup, that will push back the original recovery image + unroot the machine..right?
Pls ignore if I'm too annoying
Thanks again,
Robin
Either restore the old stock backup or flash a new stock rom
As an quite user here in the forum, it is not allowed for me to share things in the development section.
Just want share a link, which patches RR 3.0.9 with the latest MALI drivers. Therefore for all people which can not wait for an update of rr 3.0.9 it is quite fine: memory leak fixed (had been very annoying because my phone got frozen after 3 days without reboot) and enables you to use the latest dorimax kernels >7.0 (fine battery + speed)
Found the patch in an german forum:
http://www.android-hilfe.de/custom-...ma-ota-resurrection-remix-jb-3-0-9-a-162.html
the patch itself can be downloaded under the link (thank the user rush85 in that other forum):
https://docs.google.com/open?id=0BzvcR7D2Mt5KQ1JLMXJDQmFzNkk
1) I flashed over rr 3.0.9.
2) wiped dalvic. wiped extweakts profiles in cwm
3) flashed dorimax 7.3 (mali)
4) to be sure, wiped again dalvic & extweaks profile again
5) reboot
and ready to go!
--> Much faster + reliable (memory fixed) + nice powersave

a personal question & comment
by the way a question:
does anybody knows how to directly get access to the developer thread?
I have not much time to post. But I'm a heavy linux user on my 3 desktop PCs since over 6 years. Know much about linux kernel tweaks, debugging and android.
But also one critic to S2 users:
I've followed the Galaxy ACE threads for the last year and must say, that there the "developer threads" are much cleaner! No noop with "how can I flash this" or "where do I find this and that" is disturbing the replies of testing by the community for clean feedback & input for the developer(s).
- Sorry for that, but the people should just post relevant things there to make it easy for the serious testers and developers.
So after this patch ,can i flash parandroid 2.21 which ri8 now does not support dual booting in siyah ???
no. that patch is only for the ressurection Rom in Version 3.0.9.
it has nothing do with other ROMs or versions. you would break it.
I don't know who actually developed that patch. but it is working fine. next RR ROM after 3.0.9 will nevertheless have the Mali driver patches included, as the sources will be updated.
so in summary: just for the impatient waiting users of RR ROM.
Sent from my GT-P6810 using xda app-developers app
and just one thing I forgot in the first post: run also fix permissions in cwm after flashing the patch and kernel.
whilst waiting for a new RR release,
I'm now very happy with the performance and battery life of my s2! just bought ot 10 days ago to substitute my good old samsung ace 1.
Some hints for optimizing your s2
Just for because I want to know the experience of other people:
Did anybody tried that mali patch?
I'm running it since the first post here. My tips for an excellent battery life with good performance:
Remember I'm using the combination of RR 3.0.9 + mali patches + Dorimanx Kernel 7.3 (need the mali patches)
Make use of the extweaks settings to undervolt GPU (800 mV is ok for mine at low frequencies) and enable some sleeper mechanisms. I undervolt the CPU with the app cputuner (for all frequencies -50 mV; otherwise unstable for me). Because I'm a lazy person I automatically adjust the brightness via lightsensors (Velis Auto brightness app works fine; but also eats some small cpu time).

For improving deep sleep times:
[A] Additionally I found out that it is really wothfull to get a baseband matching RIL modem configuration to get over 95% deep sleep. A good tool to check/correct this is:
"GetRIL"
I deactivated also "fast dormancy" (I'm on O2 in germany) with the App:
"Fast Dormancy Toggle i9300"
[A] and really did the trick to get a high amount of deep sleep for me. Without I had just approx. 75% and now up to 98% in G2 mode.
Playstore Issues due dpi change:
If you get problems with app compability in playstore after you changed the dpi in build.prop, I recommend to search for the "multi dpi playstore" replacement here in XDA.
Last thing which is interessting: no use to lower the CPU >200 MHz. Why with a clockfrequency of 200 MHz the equinox CPU is at the best rate of calculation speed / powerconsumption. Therefore lower frequencies: lower energy but more time to finish tasks --> worse than 200 MHz.
An really good and technical/scientific investigation with hardware measurements of voltages and power consumptions is given in a german forum FACTS and MEASSUREMENTS agains wild speculations:
http://www.android-hilfe.de/samsung...80670-info-akkuverbraucher-des-galaxy-s2.html
Nice post, I will try this out and give some feedback. I'm still on rr 3.0.8 and dormanx 5.82 but I want to update

What are you browsing with? I had the same problem, but it is probably the browsers you are using. Are you using stock android browser? I used opera mini browser, and the page loads quite differently and gives you an option to download the zip file.
hi everybody. sorry hat i did not replied for a long time.
yes hat mali patch Form a Google drive must be downloaded by click in 'Datei' and then hit something linke download AS ZIP. unfortunately that forum is in German.... also the nice poeweconsumption measurements I posted a link for. maybe someone has the time to make it a viable in English for everybody.
you can flash the malipatch zip over a installed rr 3.0.9 by cwm. don't miss the wiping steps and fix permissions.
At the Moment I am on RR 3.0.9 + mal patch + dorimanx 7.4. a perfect combination for me.
by the way. I always activate in the developer options the 'disable hw overlay'.
feels smoother for me.
so let us hope that the next RR release will have the Mali patches inside. .... but until that release I already enjoy this combination. - until now no reboot had been necessary due to the old memory leak seems to be gone.

I similarly have much to share at times, but I guess you just have to post to post. It might explain why there are lots of irrelevant comments.
About your critic to S2 users, my guess is that the S2 is a lot more popular and hence you would have a lot more people asking questions. The upside is you have more developers making awesome stuff on it.
OH and about the patch, will try that later.
Again: How to download

Call me old fashioned, but with things like firmware, roms and updates (not inly for a mobile, but other devices) I don't trust wireless. I always download serious things by desktop pc. There the download is quite fine with any browser. I used firefox. there is a screenshot attached.
But maybe this patch for 3.0.9 is not necessary, as we may get a new RR version this week. ? Let us hope the developer has some time after the the milestone release of the AOSP team is ready.
nice work!
can't wait for the next RR update

Finaly success! Downloaded it! Install the google drive app and done!
Hey XDA! Today I come here to make some questions about boosting the speed of my phone.
First question: As there isnt any custom ROMS or Kernels for E615, can I overclock it to 1ghz? (I have 800mhz and feel it too slow)
2) What Values for minfree should I choose at V6 Supercharger script?
3) Yesterday when I tried to launch again Supercharger script, it said that file system is read only, how can I solve it?
4) Last, how can I disable Compcache? Is "Swap " better?
Thank you!
Try fly on mod,its cool and worx great with v6,read first post in this thread for more info,even about read only etc.
GREEETZ WITH BEATZ!!!
for boosing
try the super charger..it works like charm and it speeds the system but there are some small issues
Here's a question.
and yes, I did read most of the A500 stuff before posting this.
I currently have CyanogenMod V 10.2, and a 4.2.2 kernel
Here's my question. I see in the recovery rom, an option to overclock.
how can I do this from inside the normal kernel? is there an option I just haven't seen?
I understand it needs to be be done inside the rom, but seriously, haven't seen any discussion on how to get this running on a regular basis.
thanks in advance

Why not make it easy, download and install SetCpu or any one of the multitude of OC apps on the market, and just set your OC/UV from there? You can select "set at boot" and it will retain your selections in the event of a re-boot.
Not all kernels are capable of OC/UV. This is all dependant on if the dev compiled the kernel with the correct frequency and voltage tables to allow this.
The fact that the CWM recovery has options, has 0 impact if the OC can be done. The OC option is in every recent CWM recovery version regardless of kernel being installed.
So my advice, download and install an OC app from play store, and check if your kernel supports it.
One more bit of advice... do not select "set at boot" until you have checked out your OC/UV settings.

Thank you very much. dumb Xnix person that I am, didn't think to check if there were any apps like that. will investigate.

There are a ton of free apps. System Tuner, NoThrills, PimpmyCPU, etc. Personally, I like SetCpu (free version here at XDA, use search), and System Tuner.
