[Q] Black Screen - Sprint LG Optimus G

I am running Pac Rom 10/8 and every few hours I'll get a black screen when trying to turn the screen on and I am forced to hard reboot the phone. Anyone else having this problem? I want to know if it is a common problem with 4.3 roms since I never had this happen when I was running ZVC. I even clean installed 10/8 and didn't dirty flash to update it.

ever mess with kernel settings? thats called sleep of death

[Q] CM6.1 wake issue

So i just swiched from virtouos ROM (sense) to CM6.1 and i am having a problem.
when i first flashed virtouos, sometimes my phone screen wouldnt turn on with
first attempt but after setting profiles on setCPU it was fixed and didnt happen anymore now with CM6.1 i am having a slightly different problem the screen doesnt turn on when i am receiving a call (it rings though) and i have to press the power button couple of times to get the screen on. i have already set some profiles on setCPU ,i am just wondering if there is any fix for it ?
Thanks
Only thing anyone can probably suggest is turning up your min clock speed. What are your profiles set to?
My screen off is 245/368 just to give it that bit extra to guarantee no wakeup issues, not that I had any to begin with, better safe than wanting to throw her up the wall (I get annoyed easy).

Doesn't sound normal... did you make ANY customizations at all? Or did you install CM straight up and just use it like that? Any adjustment to "performance settings" or CPU clocking? What SPL and radio do you have installed?

no i didnt make any customization its just CM6.1 although my max clock speed is at 1497 mhz
setCPU
Screen off max 368
min 245
and profiles for temp and battery as well
the wierd thing is it doesnt happen at all when im just waking the phone up it only happens when its ringing i am thinking its my CPU issue ,i dont think it handles overclocking well ,i couldnt go over 1.1ghz (it would freeze instantly) with virouos that was the main reason i switched im gonna play with with cpu profiles for a while and see if i can get it fixed.
btw i have never flashed any radio so im guessing its the stock one
wow this is very intreasting its actually fine without any setCPU profiles
i had something totally different in my mind.

With my experience I've noticed the phone runs better, and lasts longer on a single charge WITHOUT setCPU profiles. Just my opinion

And there you have it. Overclocking can do weird things.

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] CPU not using any speed other than max.

I have looked around and completed a few searches but cannot find any direct answers to this.
I have CPU Spy installed and have been checking it off and on since I got the phone. I have noticed that my phone does not run at any speed other than the absolute max. The phone does go into Deep Sleep without issue, but the only CPU speed it uses is 1728. I have tried a few ROMS without any change.
Currently running Juggernaut 5.0 with Darky's Kernal.
I have tried different Governers. I have tried Antutu's CPU Master, SetCPU and No-Frills. I just cannot get this phone to run anything other than MAX speed. Since I am constantly having things run in the background like music, this is effecting my battery life.
Anyone have any input, ideas or suggestions? Other than running stock.
Turn down your minimum CPU settings in set CPU and check set on boot?

You've done just about everything possible. Only option left it to Odin back to stock, root it and check cpu Spy to see if it is acting normal. If it is back to normal flash back to your favorite distro!
Perhaps something got messed up along the way of flashing all those roms? Shouldn't, but you never know.

I was really hoping it would not come to this :'(
*update....
I re-flashed Darky's Kernal and removed all OC apps and now I am showing full utilization of the different seed steps.
Quite glad it did not result in me having to start over again.

lockup during sleep

My phone locks up 2-3 times a day when sleeping. When it locks up, the "SAMSUNG" splash screen briefly flashes, and the phone vibrates. If left alone, it gets warm. I have to hold the power button or pull the battery to restart it. I have been unable to adb into the phone to get logcat or dmesg after it locks up. Also, this never occurs while the phone is plugged in. I have tried Darkside v8 with both Venom and Faux 008 kernels, as well as Jedi Mind Trick 8/18 with Faux 009. With Darkside, I tried changing the screen-off governor with System Tuner to ondemand as mentioned at http://forum.xda-developers.com/showpost.php?p=29559002&postcount=8633, but it didn't help. Is there anything I may have done wrong, or any way to fix this? Thanks!

With conservative governor and screen-off set to no governor change, it crashed this morning. Running Mind Trick 8/18 with Faux 009.

I set the governor to ondemand and rebooted. Phone locked up within 10 minutes. Also, if it helps, I had Venom clocked at 384/1512 and Faux at 384/1728 (since I can't lower the max because of DVFS). Darkside v8 ran fine for about a week before the crashes began.

When you say lock up you're talking about sleep of death correct? Have you logcat afterwards?

It only locks up when the screen is off, and never when plugged in. I tried Streamline kernel a while ago and got sleep of death basically every time the screen turned off (and I went back to stock immediately), but this seems different (in that it doesn't just not wake up like Streamline, the phone vibrates and displays the SAMSUNG splash before it won't wake up). I tried to get a logcat with adb when it last crashed, but the phone didn't even show on my computer's USB bus. I restarted it and took a logcat and dmesg until it booted, which I can send you if you wish.
I tried flashing Gideon's stock OC/UV script (http://forum.xda-developers.com/showpost.php?p=20946429&postcount=574), thinking that my phone may just be unable to handle the default UV with Venom and Faux, but this caused it to SOD (without the SAMSUNG splash) almost immediately. I went back to my Nandroid of Darkside v8 (since Mind Trick didn't help things), and flashed Faux 009 with the undervolt set with System Tuner to -12.5mv below stock for all stock frequencies. If this doesn't help, is there a possibility that my phone is faulty? I have had it since December. Also, could this be related to the GPU or L2 overclocks in Venom and Faux (but if so, why wouldn't it crash when the phone is awake)? Thank you for your time.
If it still crashes, I have a flashable zip of the stock ICS kernel and its modules that I can try, or if extremely necessary I can ODIN back to stock.
EDIT: manual Faux UV did not help, just flashed stock.
EDIT2: It just crashed with stock kernel as well (still using Darkside v8 ROM). Since it doesn't seem to be ROM or kernel related, I'm worried it may be the phone (perhaps whatever passes for a PSU in a smartphone? It'd explain why it doesn't crash on battery power). I'll probably try flashing AOKP ICS next in case it's a TouchWiz problem. Is there anything I'm missing here, or should I ask for a warranty exchange if AOKP or stock ODIN still crashes?
EDIT3: Uninstalled System Tuner to be completely sure nothing's affecting the governor/voltage/clock/etc. (still Darkside v8 ROM, stock UVLE1 kernel), crashed within 15 minutes of restart.

I would put stock ROM back on it take it to a t mobile store and show them what's happening. If you have warranty they should replace it. Your CPU is shot. It won't go into deep sleep. And when running stock, it's not a software issue. It's hardware.

I was worried about this. I will ODIN back to stock tonight, but I won't be able to take it to a t-mobile store for a couple of days. Thank you for your help.
EDIT: I have been running stock UVLE1 (kernel and ROM) without root for almost a day now, and it has not locked up. According to CPU spy, the phone is able to enter deep sleep. Could there be something in the custom boot scripts used by Darkside and Mind Trick that my phone doesn't like? It's about the only thing I could think of that would not be fixed by the stock kernel. I might try re-rooting and/or flashing AOKP ICS in a few days if my phone holds up.

[Q] display problem when UV

im using ncx 099a kernel and since i flash these kernel, the screen sometimes flicker like hell......this is happen when im palying game and then it continue to shake the display...when im trying a force reboot to bootloader, the screen died only vibrate...but when im push longer it go to bootloader mode ok...try to restore nandroid but still the same..
and some other times, there are strange pixel color showing up....
i try to fix this by OV my phone a little...and now everythings fine...
my question is, is UV or maybe any other setting to kernel or rom will have this massive effect on our phone...
No
No not until u underclock it to extreme levels.

underclock...mine is lowest to 51mhz max to 1300mhz....this is the setting from the kernel
undervolt...i think not that extreme...i have been using the same setting even when in my evo 3d...just -50mv from original mv..
