[Streak 5 Q&A, Help & Troubleshooting] dmandic:
Amazing! I have exactly same problem as you, and with similar timeline! (starting to think it's like some Dell timebomb to force us to buy new tablet ;-)

Already tried everything like you. When works, it's OK until it start to connect to 3g, connection works for some time (minute or so) and then streak freezes (i need to remove battery) or reboots with flashing buttons. After that, it simply turns into Dell logo bootloop with battery draining (and overheating) fast or it reboots to android gui and when connects to mobile network buttons flashes and reboot again.

When i remove simcard, it often boots almost normally, although i noticed few times that it was reboooting without simcard, but much less frequently.

Then i need to remove battery for few hours, after that, it usually it turns on (better luck if i remove sim card).

Hoped that it's some kind of software error, but when i tried almost every available rom (stock or modded) i'm pretty much convinced it's hardware problem: some electronic failure, possible overheating sensitivity (although i did checking battery temperature when reboots happened - it was not as much - 30-33°C) or internal sd failure (although i can't see what it has to do with simcard as a source of problem...).

I tried 351 stock and amss and dsp, and did not help.

htcjikelly, please report if you have find some info about our problem (i'll do same)

unfortunately, i noticed that normal working periods are shorting rapidly, so i think that problem is progressing, and wouldn't be surprised to se my streak dead soon :-(

hopefully not before i try my warranty...
[Streak 5 Q&A, Help & Troubleshooting] htcjikelly:
I have not been able to restore my Streak to total rock solid function. My brother had one lying around and he gave it to me. :)

So now I have one of the white streaks with 1.6 on it. I want to pull a backup from this new phone to see what that will do to my old one. I've got to figure out how to do that first though.

There's got to be a way. Maybe I can copy everything off the white one's internal SD card and copy it to my old one.

The warranty. I purchased one from squaretrade and I supposedly have one with AT&T as well. Maybe I should look into that.
[Streak 5 Q&A, Help & Troubleshooting] xateks:
Same problem here

I have the same problem with my streak, it randomly reboot, the lights flashes some times and it stay in a loop for a while.

But I live in Brazil, and can rma this thing, actually, I can do nothing, because it wasn't launch in Brazil oficially, and it's second handed.

I need some help.

Was hoping to get a litle help with my wife's Evo.

I rooted her Evo and flashed the stock Sense ROM.

Everything works great with one exception.

She continually gets a Voicemail notification that says she has 3 voicemails, however, there are actually no voicemails. (hope that makes sense)

She can get rid of this by going to settings-call-clear voicemail

We were hoping that there is a permanent solution to this problem.

Would appreciate any help.

Thanks

[EVO 4G General] Skid71:
Interesting Nick. Assuming you haven't found a permanent fix for this either?

Obviously it's more a pain in the arse than a big problem, but would like to eliminate it nonetheless.

Thanks for the info. Yep, she is on 4.22

Looks like I'll have to do some more work on her phone.

Original Thread - http://www.villainrom.co.uk/forum/showthread.php/4874-Myth-Busting-SetCpu

Right I was a little late into the SGS2 game, as many of you know I had to wait quite a while for my phone to arrive due to a system error at my carrier OrangeUK. I have now had my phone for 2 weeks and been using SETCPU since day 1.

Now I am not sure where the said myth has come from but you all have probably seen someone say it, or heard whispers of it. It goes something like this:

"SETCPU DOES NOT WORK ON THE SGS2"

Now this is a lie!!!!!

I have been a user of SETCPU for a long time, a paid user so granted I was a little biased when I chose to use it on the SGS2, however I am not stupid enough to continue to use an app that is not working so despite everyone telling me otherwise I did install the app.

And to mine (and others) surprise it was working perfectly

I underclocked my main profile to 800mhz and made a profile for screen off 200-500 conservative and have been monitoring my time in state ever since.

And has it been wrong? at all? ever??? HAS IT HECK!! its been perfect every time

Has my phone failed to wake?? Got stuck at a certain clock??? used a clock that it higher than my max?? NO! NOT AT ALL, NADDA

Please please please stop spreading idle rumours and whisperings of things you have not had time to properly investigate yourself. Set cpu is a great app, made by a great dev and does not deserve to have people not use it because a few people decided that it did not work.

Maybe it didn't work at first, but SETCPU has been updated 3 times since the SGS2 was first released, all I know is for the last 2 weeks its worked perfectly yes at least 20 times I have seen someone say on xda/twitter/irc or somewhere that setcpu does not work.

Please stop this now!

[Galaxy S II Themes and Apps] blickmanic:
works fine for me too ha :p
[Galaxy S II Themes and Apps] XpLoDWilD:
I can only confirm this. Using SetCPU since I rooted my SGS2 (so a couple hours after I got it :p), never had any wake issue, freeze or whatever. It's easy to check if it works, just limit your CPU to 500MHz and check some Flash websites ;)

Ondemand on screen off (200-500MHz), and some profiles when low battery and such. Otherwise it's set to ondemand 200-1200MHz. Working fine.
[Galaxy S II Themes and Apps] hg3atintin:
Mine only works with screen of 200-800 mhz. But maybe thats because mine is uv.

Conclusion: Latest SetCPU works on the SGSII.
[Galaxy S II Themes and Apps] tolis626:
LennyUK,you are both right and wrong pal.

First,yes,all these rumours with SetCPU not working on the SGS2 are pure bull****.I've been using SetCPU since I bought my Desire and it's worked every single time.On my SGS2 it works like a charm,UNLESS I am heavily undervolting with Tegrak Overclock Ultimate.Now,this is where you are a little wrong.SetCPU profiles sometimes conflict with Tegrak's app.Especially the screen off one.Why this is happening or exactly when is completely over my head.I want to do some testing though.For starters,I think I'll raise my 200MHz voltage to 825mV and see what happens.

I myself have experienced such behaviour.The phone wouldn't wake up unless I pulled the battery and SetCPU's SCREEN OFF PROFILE,NOT THE APP ITSELF was the cause.However,it never happened with Cognition,where I couldn't use Tegrak's app.

To sum it app,SetCPU is an awesome app by an awesome developer.It's well worth its money,even if it doesn't work well on one device,even if that device is the Galaxy S 2.Not that the latter is true,it works pretty well,but just sayin'.Maybe Tegrak would have to make his app more "compatible".Maybe not.We'll see! :)
[Galaxy S II Themes and Apps] Lennyuk:
Yeah that is where common sense should kick in, you should not be using 2 apps that do the same thing (or near enough the same thing) it is bound to cause conflicts!

[Galaxy S II Themes and Apps] ithehappy:
Well my friend advised me to use this app for battery back up improvement and I purchased it from Market, used it for two weeks. Tried every possible setting I could, and at the end, it's uninstalled. Well setting it 200 MHz shuts the phone off, that's ridiculous. I used On Demand mode with Min 200 and Max 1200 MHz. Now don't tell me I needed to set mine to 800 MHz, it's really funny and crazy that someone using his/her 1200 MHz CPU on 800 MHz. Undervolting and Underclocking is OK when you are sleeping but continuously keeping it at 800 MHz is weird. Anyway, after two weeks of use, I didn't find any sort of improvement in battery life. I don't know if some people uses this application for Underclocking or to get more juice outta battery, if it's the latter one then you will be disappointed. I am saying BS, well the app costs just US$ 2, so go on and buy it, then state here how did you like it.

To sum it up in a line, I DO NOT recommend this app at all to improve battery back up.

Regards.
[Galaxy S II Themes and Apps] Stwzzz:
As i just switched to 2.3.5 i cant say anything about the battery life. But what I can tell you is that setcpu works
[Galaxy S II Themes and Apps] wltklah:
my setcpu 2.2.4 isn't working on my CF-Root KI3 kernel, stock KI3 2.3.5 ROM ... The setcpu launch without problem, ondemand, conservative, powersaving, etc..works, but setting the max frequency on the main profile doesn't seems to work. CPU still go over the max limit I set when I exited setcpu(its process was still running). It works and regulate the cpu as told when I am in setcpu. I checked on the CPU state time in setcpu and it also suggests cpu were running at higher speed than the max limit. Any one notice this problem??
[Galaxy S II Themes and Apps] hjuo:
Me too on KF3 and others before. I don't know if there is a solution. However I noted that if I set it low to 500mhz it doesn't almost never beyond 800mhz
[Galaxy S II Themes and Apps] jayquinten510:
I think I recall reading somewhere that the phone needs to go up to 800MHz before it can go into deep sleep and that is why it is doing it.
[Galaxy S II Themes and Apps] D.O.C:
Set a profile for screen off on setcpu determining the same freq as ur screen on governor.

That would be the dynamic cpu handling not working correctly, u must disable it viar init.rc, harcode it into kernel on cpufreq.c or disable it via adb shell.
[Galaxy S II Themes and Apps] alstrike:
I never had any problems with SetCPU.

Well to be honest I had some freezes when I used Galnet a couple of months ago, where the voltage I set was a bit too low and the device wouldn´t wake up.

It´s a great piece of software, although I´m not playing with voltages anymore because it renders the kernel developer´s work useless (sort of).
[Galaxy S II Themes and Apps] 1xinfusion:
Read the AOS bug thread. It describes problems with deep sleep.

If you are experiencing 800mhz a LOT and Android System is using High CPU % then you have the AOS battery drain bug
[Galaxy S II Themes and Apps] wertyo:
I've been having serious problems with battery life from my S2. From the go, my battery life has been horrendous. Before having the phone rooted or anything, I went a long train journey (about an hour and 15), and did nothing with my phone in this time other than listen to music. Battery dropped from 95%-42%

Now because I had just got the phone, I had no clue how long the battery should last. Did some research and saw people saying "i get nearly 2 days" blah blah. So i tried the whole shabang! Rooted, new rom, new kernel, new modem. Battery life improved a bit, but not significantly. Thought it might be a battery calibration error, calibrated battery. Still not much better. So here i am today, have installed JD and SetCPU.

I usually leave my phone on charge throughout the night, last night i decided to see how much battery is used. Battery was at 68% when i went to sleep. 10 hours later i awake to see battery at 20%. Now correct me if i'm wrong, but 4.8% per hour just doesn't seem right to me. In this time, the phone kept going "awake" for reasons i cannot seem to find. Presumably background apps syncing?

I'm running VillainRom 3.0, ninph 2.1.3, on android 2.3.5 with KH3, and using launcherpro!

Am I doing something wrong that's causing my battery to be drained horrendously for no reason?

My battery usage comes out as display highest, followed by android system and android OS.

I did have a problem yesterday where android OS was taking a ridiculously high amount of batter (higher than display). A simple reboot seemed to resolve this.

And one final point, after the battery dips to 15%, battery usage seems to drop dramatically! To about 1% per hour! I know power saving mode is activated and all, but even if i use power saving settings on higher charge it doesn't seem to make a difference. I'm thinking battery needs calibration again?

So moral of this long and pointless post, I've installed JD and SetCPU with Lenny's settings. Will post my findings in the next few days.
[Galaxy S II Themes and Apps] wertyo:
Here's my findings:

JD and SetCPU combined works absolutely beautiful magic!! Although at this point i can't differentiate which one is having more of an impact on my battery life. At the moment i've been on battery for 16 hours, with the phone awake for nearly 5 hours, screen on for nearly 3 hours and wifi on for nearly 2 hours. Still have 31% left. Normally my battery would have been cold dead by now! Wasn't extremely heavy on the usage today, but not extremely light either.

An absolutely massive thank you to the creators!!

Deep Sleep - SetCPU

I have found if you set a Screen Off profile, your phone will sleep at 200Mhz. Most ROMS have their own deep sleep mode so not setting a screen off profile fixes this and the phone properly goes into a deep sleep. Thats what I have found..
[Galaxy S II Themes and Apps] mbroeders:
Not necessarily i think; I've tried several roms, all with a screen-off profile, and all of them properly go into deep sleep mode. I don't think that SetCPU is to blame when your phone doesn't go into deep sleep mode.
[Galaxy S II Themes and Apps] Schindler33:
I agree with you. I use a screen-off pofile and my phone deep sleeps normally. I just use it that if some apps continue or cause wakelocks they will only run on 200 MHz.
[Galaxy S II Themes and Apps] extract1:
Ive been using Lennys profile for screen off min200 max500 on conservative and my phone never went to deep sleep mode. Once i set the screen off profile to min 100 max 200mhz on smartassv2 it stays in deep sleep mode all the time :)

SetCPU is NOT working on my rooted SG2 2.3.5

Hi

For me SetCPU is

NOT

working on my rooted SG2 2.3.5 !

SetCPU, CPU Tuner (and properly other apps) can't adjust CPU speed unless you flashed kernel/ROM that supports this!

The cpu clearly and constantly exceeds limits set in Main setting and/or in Profiles.

CPU Tuner actually inform about this fact ;) ... SetCPU dosn't :mad:

Anybody on stock SGS2 rooted PLS confirm this ...

And if anybody found a solution to make SetCpu work on official ROM (in my case 2.3.5 from KIES) I will be happy?

Thanks

Works for me on cfrooted KI3 kernel. Underclocking only. No voltage control obviously.

You could try siyah kernel 2.0
[Galaxy S II Themes and Apps] Mittaa:
Thanks for your reply ... but I don't think I fell ready to flash.

In fact I love my phone as it is.

Only reason for me to root, was to get rid of Samsung blot ware ... and being able to under-clock my cpu in order to save battery and chill it a bit down.

Don't need to tweek volting ... just simply under-clock.

[Galaxy S II Themes and Apps] adam_pl:
If You mean by "default" no profiles enabled in app, than all I did was remove battery after freeze, put it back and reboot. After that I just simply unchecked both profiles.

Maby it's due to Siyah 2.1 kernel I'm currently using?
[Galaxy S II Themes and Apps] snailmale:
Hello, can I check if SetCPU and Voltage Control work mutually exclusively? That is, can I run both at the same time without much additional battery use? The main reason is that I'm looking to use the screen on/off profiles for SetCPU, and the GPU undervolting capabilities of Voltage Control. I'm using Siyah 2.1.1 right now. Will I have to set the under/overclocking limits on both? And will they interfere with each other?
[Galaxy S II Themes and Apps] Entropy512:
This only works if you're on a custom kernel that has coolbho3k's Sleep of Death patch.

All Samsung devices with Hummingbird/Exynos CPUs prefer to enter/leave suspend at 800 MHz. There's a bug stock kernels that will cause it to enter/leave suspend lower than this ALONG with setting the voltage for a lower speed if the CPU max policy in SetCPU is set below 800 MHz.

Many custom kernels contain the aforementioned patch which fixes this, such as Ninphetamine and all of my kernels for Infuse and I777 (AT&T GS2). Some may not - people will encounter SoDs on these kernels if they set any profiles with limits below 800 MHz.

Edit: I believe this kernel bug is the source of SetCPU's bad rep on Samsung devices. It's the only app that supports screen-off profiles to my knowledge.

Custom voltage terminology - Please explain

I have read in some threads about undervolting the phone. I want to know what exactly it means.

The default voltage for 200MHz is 950mV. Does this mean, if my phone is on 200MHz for one hour, it will consume 950mV charge from the battery?

This doesn't seem correct to me, because at this rate, the battery (100% is 4.2V) will be empty in (4200/950) hours, which is less than 5 hours.

Can someone explain how these voltages work?
[Galaxy S II Themes and Apps] anisbombaywala:
Before installing SetCPU my major hits when the phone is used was to the 1200MHz and 200MHz. Deep Sleep always got activated as soon as idle.

After installing SetCPU (with the gov still as default onDemand) the only change I made was increased the max to 1400 and decreased min to 100.

Now the major hits are on 1400 and 100. Deep Sleep still working as expected.

IS THIS GOOD? Because the phone can now hit beyond 1200 (up to 1400) when required. And remain below 200 (at 100) when appropriate. Is my understanding correct?
[Galaxy S II Themes and Apps] huuub:
SetCPU fans, riddle me this please.

I put the min and max Mhz to 500. (keeping it on 500 in other words)

To test it, I use StabilityTest CPU/GPU test. (test CPU+GPU low details)

And I use the normal 950mv. Crash...

Even when I increase the voltage to 1000. Crash...

1050 crash after 1 min or so..

What is the problem???
