setCPU problems...need help

Ok i have my g2 currently oc'ed to ondemand 1497 max 245min and my problem is when trying to wake the phone. i press the power button screen flashes and then get a black screeen. i have to press the power button a couple of times in order to get it to wake up. anyone know how to fix this.....phone works fine when i restart and have a normal clock speed but when i overclock it i always get the wake problem.....

That's the risk you take when overclocking! Weird things start to happen the higher you go. Some phones can go higher than others.
I would back off a little to find your sweet spot.

Some people have had problems with the SetCPU widget, do you have that on your homescreen?

Yup... thats pretty normal behavior. I get it once in a while...

ok yea i lowered the max to 1209 n it seems to be working better now....

That's normal and happens to me. Avoid hitting the power button twice in rapid succession and you won't have that problem.

I always had the same behavior until I installed CM6.1 I have not experienced the issue since and I am still overclocked. My guess is that its a problem with the stock ROM.

I was having this problem with SetCPU as well on Virtuous v0.7.2 (Sense, 2.6.32.26-cm-virtuous-v1.1 kernel) and I solved it by creating a SetCPU profile for "Screen Off" with the default settings (806400/245760, scaling set to ondemand, priority 50). Works like a charm and I never get any hang ups after turning the screen on!

I also had this problem with virtuios rom,so i installed the pershoot kernal and that fixed my issues with the screen. No more problems since.

Which kernel should I have if I just want OC?

My phone is rooted and has s-off but I have a few issues. One is almost half the time when I hit the power button the screen doesn't turn on instantly but the soft buttons light up. It usually takes me hitting it 2-3 times swiftly to get my screen on. Another issue is sometimes wifi calling gets screwed up so it doesn't work and it drains my battery as a background task stuck on restarting. I really only want my phone overclocked so just have baconbits kernel. is there a newer version I should put on that fixes these issues?

Baconbits, to my knowledge, is the only OCd kernel available for the stock ROM. Your screen issue might actually be caused by underclocking though, do you have a screen off profile or a minimum set?

I just have it set to 368-1497. Should I up the minimum?

Give the overclock widget a try. Its available free on the market. In the advanced setting, set your screen off profile to 245 min and 806 max. Scroll down and hit "save" before you exit settings. That will keep your phone running at stock speeds while the screen is off and should stop the wake issue you're having. When you're using the phone you'll be at the higher speeds.

I already had the widget. Did what you said but it still occurs.

245 is *way* too low, especially if you have things running in the background ... just start raising the lower end up until it stops happening.

Setting it to stay at 800 while the screen is off seemed to fix it. Any ideas about wifi calling bugging out? It usually doesn't happen very often, I think when my phone has been on for a while without a restart.

overclock widget doesn't overclock anything.... it controls the speeds AFTER you've installed an overclock kernel. I highly suggest using flippys turbocharged 1.8ghz kernel. Just because it is capable of 1.8ghz doesn't mean that you need to run it at 1.8ghz. you can just do something like 1.1 or something in between. Give it a look.

Nobody said the OC widget overclocked anything. Did you read the OP's first post? It was suggested so as to enable a screen off profile because the OP is having a wake issue while using baconbits.

set the off screen profile to the lowest speed 200/200mhz and 100% priority and he wont have anymore wake issues, don't know what I was reading hahaha

The screen on issue doesn't happen anymore but I'm not satisfied with my battery life. In the past something was causing my battery to drain insanely fast so I un installed a bunch of unused apps and started checking background tasks but when browsing the internet for 20 minutes on my way home I use 30% of the battery, bluetooth on.

Anyone know if it is possible to run Pershoot's kernel on the stock rom that comes with the device? Any side effects?

I don't know enough to say 100% one way or the other, but I read in a post I can't find right now that only BaconBits is made to work with the stock rom.
FWIW, I tried to flash the 1.8 GHz kernal on my stock G2 this morning, and got stuck in a boot loop.

On AndroidCentral people are saying they have improved battery life with CM7 nightlies. I'd like to try running a ROM finally. Do I need to get rid of my Baconbits kernel before proceeding? I already backed up everything with Titanium.

NO. The first thing you need to do is flash clockworkmod 3.0.0.5, which is totally different than ROM Manager. As of right now the latest clockworkmod available through ROM Manager is 2.5.1.3. If you haven't flashed that yet (2.5.1.3) do that first through ROM Manager. The best way to flash 3.0.0.5 is to find the .img file, place it on your sd card and run the commands from terminal emulator. After that just wipe data/factory reset, wipe davlik cache and flash the latest nightly .zip, reboot, then the latest gapps .zip. Go to the development forum and the first post in the nightly vendor vision thread has all the links you'll need.

[Q]How to wake up w/o battery removal?

How to wake up the phone without battery removal? I have Virtuous 1.0.1 ROM with advanced kernel and from time to time I have wake up issue. I would like to avoid removing battery because I have otterbox case on my phone.
Do you know any other way to wake up yhe phone?

Well if you can't wake it up with the button on top it is a problem. Are you overclocked? Try lowering it.

Open the keyboard....lol

wake up
I have seen the same behaviour with the stock htc latest (1.82.whatever).
top switch -- othing
opening kbd -- noting.
only a removal of the battery seems to help.
Of course it hasn't happened in a convenient place e.g. to see if I can still access it or if charging works etc.

If u installed trackpad wakeup, it seems to distort virtuous roms and keep the device from waking up all together.....there are posts about it in the developers forum

Also in some cases this is caused by underclocking with a screen off profile. I actually gave up on virtuous untill that problem gets solved. I havnt tried the latest version though.

There are 2 distinct "screen on" issues with slightly similar symptoms.
One is the "screen wake issue" what is common with Virtuous, and typically caused by certain combinations of overclocking, and screen off profiles.
The screen wake issue is very well discussed in the Virtuous thread, and commonly/easily solved with the proper screen off settings.
http://forum.xda-developers.com/showthread.php?t=967153
But the screen wake issue, as far as I have experienced, manifests with screen sometimes flickering on for a second, and sometimes responding to multiple presses of the power button, or by opening the keyboard. There is a different issue, some have called "SOD" (screen of death) where the phone seems completely dead until you pull the battery and reboot. This seems to be more what you are describing, but I'm not sure. The cause of the SOD has not conclusively been discovered, and there is currently no known surefire solution. But it may be hardware and GPS related, maybe kernel related. Personally, I've experienced this across several custom ROMs (Virtuous, CM7), kernels, as well as stock. The only luck I have had, is that the stock DZ ROM with the Godspeed kernel is the only combination which seems completely free of SODs. One person sent his phone into HTC due to SODs, and they said it was caused by a faulty GPRS module, and fixed it by replacing the mainboard. Another person send this phone in, and it was returned untouched, with the same problem still present.

Why people still do this just boggles my mind. All current kernels drop the processor down when the screen is off. There's no need - at all, for a screen off profile. It creates a wakeup issue as you can tell since SetCPU has to refresh the phones state then switch profiles in order to allow the processor to move into a higher state. That takes a lot of time (in computer time) thus creating this 'bug' that doesn't actually exist. The OC bug however does exist and is present no matter what you do aside from keeping it at 1.1GHz or less.

I had the screen wake issue on Virtuous, with NO screen off profile and OC'ed to 1 GHz. Making a screen off profile, but leaving a wide range for the CPU speed (not underclocking it) and interactive governor solved the issue in my case.

That might work better since most people I've seen tend to use the conservative or powersave gov. in their screen off profile. I'll correct myself too, what I said was from a CM standpoint since I've yet to use Virtuous.

Yeah, the screen wake issue on Virtuous is different from the one on CM7. If I remember properly, on Virtuous, using the advanced kernel results in screen wake issues for everyone or most people, unless you make some SetCPU/CPU Tuner setting adjustments.

Do you have SetCPU, or another program capable of CPU clock control installed? If not, install one of them and bring the max clock down... the Advanced Virtuous kernel boots at 245min/1516max - I noticed this after a fresh install of Virtuous 1.0.1/2 and the Advanced kernel

Completly agree.
I am shocked and appauled that most don't seem to understand that the os and it does not matter which(I.e. android,ios,windows) or platform (I.e. smartphone,tablet,desktop,etc) when you overclock more than just ur cpu speed is changed. If u have any experiance overclocking cpus on your home computer, you know u cannot let your system hibernate because it will not wake up. All operating systems allow the cpu to completly turn of in hibernation until it recieves an electrical pulse from the board. But if ur cpu goes from off to high it pulls way to much electricity and can't process then commands because all the recouces went to waking. If you have sleep parameters set with a narrower range the system will have enough resources left to process ur intial command...when it comes to sleep to wake there are no in between frequencies.

Proximity Sensor Problem w/ CM7?

I searched but couldnt find exactly what I'm looking for. When I press the power button or trackpad to wake the phone up in the dark, it wont turn on. Only the soft keys will light. Any advice?

If you have the CPU overclocked that could be the culprit. CM is notorious for not playing nice with any speeds over 1 GHz. Set is at 1017 or whatever is closest to that and it should be fine.

I keep mine at 1.4 with no issues
Sent from my Vision using XDA Premium App

I don't see how this is an issue with the proximity sensor...
However, as per the above poster, CM has issues with overclocking. I experienced the same issue when I first installed CM7 and my options were to disable overclocking or disable the on/off animations (I chose the latter).

With CM7 I noticed the cpu is set @ a range of 245-1400. Use setcpu profile for screen off @ 245-368 and a regular profile 700-1017...you will have less diffulculty wakeing ur device. If you keep it @ the default settings it tries to jump to the highest frequency and uses nothing in between and creates a lag and sometimes even a soft reboot

Cpu problem.

I'm running jmz stock rom, no problems, but recently I've seen that my Cpu voltage has been kept at 1.4 (full over clock) and it won't come down unless in deep sleep. I've tried Cpu control apps, they don't seem to work. Not sure what the problem is.

did you change the cpu governor to performace?

govenor is set to smartassV2. ive tried changing it to all of them, when the screen is on and the phone is not in deep sleep, it is running at full speed for some reason.

that used to happened to my inspire 4G
i had to reset it . that usually fix it .

i wiped, reflashed, whatever there is i can do and it STILL is running on max cpu frequency. it makes the phone very hot, and uses quite alot of battery throughout the day. better battery stats just says that system is using the most, and that 1.4ghz has been running 100 percent of the time (unless screen off ((deep sleep)) )

if i remember correctly , it was an up doing it to my phone ,
you said you wipe and reflashed , did you installed the same apps .
honestly i dont see why using battery stats.

problem still persists, not sure why though. seems when i restart it sometimes it will do it, and other times it wont. Usually waiting for the phone to cool down, then restarting it fixes the problem. Not sure why.

Flash jmz linaro kernel and use any app to lower the cpu freq. That's how I have been using mine since v1. No heating or draining issues so far. I use smartassv2 as governor.
