[Q] Random Reboots - Android Q&A, Help & Troubleshooting

Hello, I keep getting random reboots on my HTC Legend. I don't think the problem is related to the rom because I tried many of them and still the same problem. I've read that it may be related to the radio version but I don't know which version should I upgrade to
ROM: CyanogenMod 7.1.0
Baseband Version: 47.26.35.04U_7.05.35.26L

Did u OC's the CPU? Maybe your frequencies are too high?
Try with a lower one.

Thanks for the reply, yes, i did try lower the Frequencies but still have the same problem

What frequencies are you using?

have you tried to change governor?

Currently using 787 max. and 400 min. and the governor is set onDemand

It could also depend on the Kernel installed, but for a 600 MHz processor, 787mhz seems definitely too high for me. My friend has the same CPU in his ZTE Blade and he cannot OC more than 650mhz (obviously also depends on hardware).
What I suggest, is to OC's just a little above the normal value 600mhz (ex. 633/650mhz), and increase little by little the clock to find out at which freq. your phone start to experience spontaneous reboot.
I would also try the "smartass" governor with a min freq between 19/176 mhz.
Let me know.

Some devices (with 600mhz processors) can be overclocked to 864mhz (e.g. HTC Aria; but is overall stable at 806mhz).

I am agree. My Hero can be overclocked up to 749mhz (525mhz default) , but at this OC suffer from spontanious reboot. The max freq. I can reach is 710mhz without problems.
This is why I said it depends on devices and hardware.
Probably 787mhz is too much for his phone.

[Q] SetCPU & Megatron

I tried asking this in the Megatron-thread but as usual, no answers...
I am a little worried about keeping my phone overclocked at all times, so I was thinking about downloading SetCPU and switching between 600 and 700 via that app. But my question is this: Megatron ROM overclocks the phone by default. If I download a 3rd-party app to overclock/underclock the phone, will this mess up the whole system?
Anyone? Would really appreciate help!
i've been using megatron & setcpu together for the past month.. no issues yet, so cant promise ma phone wont go up in flames i clock extra if needed
Ok, thanks!
My Experience: USing LOL rom with default OC gave me kernel panics ...so instead i disabled OC in ROm and wud then OC using SetCPu...ALso I dont know why but touch feels a lot more smoother on LOL rom with the lag fix than megatron....so i switched from megatron to LOL...Currently even with maxCPu 480Mhz and conservative profile..touch is very smooth on LOL

How do I disable the OC in Megatron? By adding the "minitron" file and then using SetCPU?
Hi all,
I'm a newbie in Android world. Successfully flashed my O1 to Megatron v1. Afterwhich I tried installing SetCPU to it and overclock to 806mhz & above. However, after overclocking with SetCPU, the whole phone's performance became more sluggish than the original Megatron 729mhz...
Someone please advise me on how to overcome this and make the phone speedier with high frequency.
Is there a way to edit some of Megatron's kernel to make it 806mhz on default even without using SetCPU?
Don't use set on boot feature, it will make ur phone get stock on bootloop...
So can someone tell me how to proceed with this? I want to be able to change between 600 and 700, when I please. Thanks

Got it! Tried last night without set on boot feature. Working fine with 806mhz and speedier than 729mhz. However my chipset refuses to go into higher frequency without freezing and rebooting... Is it due to my microsd card? I'm still using the original 2gb microsd card tt came together with the O1... Will changing to a class 6 or higher microsd card let me clock higher? or my chipset is just lemon at 806mhz?

FnH84: I downloaded SetCPU from XDA forum and can tweak the frequency between 600 & 700 by myself. Even can set profiles to govern the speed at different situations.

You are already pushing the CPU to its limit with that 806 MHz frequency. Do you even realize is 34% above the designed specs for this CPU? You're already lucky enough you got it stable at 806, and no SD card will ever make a difference, they're not related.
How come Samsung Galaxy Mini running on the same chipset offer 800Mhz as stock???
Man, I don't know! How come the same "Pentium IV" processor could come in speeds from 1.3 GHz to 3.8 GHz?
Can any of you actually believe that LG would underclock an 800 MHz CPU and sell it to us as a 600 MHz instead of letting it run at its best?
Galaxy Mini is obviously using a CPU designed to run at 800 MHz, even though it bears the same name. And that one can probably be overclocked to above 1 GHz.

Thanks for your reply. I was thinking bout the same as the other guy, that galaxy ace can run at 800mhz, and why not O1.
Hmm... Isn't there any other ways to push the frequency higher? Maybe supply more voltage to the core? I dont mind sacrificing batt life, I just wanna try ways to push it to the max~~

[Q] Why is OC over 729 MHz unstable on P500. ?

Guys... I just wanna know the reason behind the OC mechanism of P500 that does not allow it to OC beyond 729 MHz in stable form. .
Whereas the GT-540 with same CPU gets easily OC to 900 MHz.
Please somebody reply to this..

Because the HW (chip) is not rated to run at such frequency. If you are lucky, you will be stable @806MHz or whatnot. If you are not and got the less perfect silicon, they you will crash even @ 729. Nothing above the stock frequency is guaranteed.

Yep, it actually depends on the device itself.
Gt540 at 900 MHz have you looked at our forum on m6 we can't get past 806 stable oc some of us 844 tops anything past that unstable plus crashing constantly we all want the Max but its hard to achieve better to focus on swap ram io speed stability

I'm running stable at 787. Had a few crashes but I think it was the ROM because I reflashed and no problems since then.
i think it also depend of the kernel becuas with the first kernel there was for our phone i could go to 748 witho no problem then with matt kernel only to 729 above tha eventuality the phone crash with franco i could go to 768 but sometimes crash,so could be hw yes but the kernel also help and have a big part in oc...

[Q] 1.4GHZ all the time

after root... i have installed SetCpu, i have overclock my processor to 1.4ghz.. the question is, can i use this setting for daily use? is it will cause my processor hot or damage??
Every CPU is different, some can handle 1.4, some can 1.6 and some can't even 1.3GHz.
I've been using 1.4GHz max and 400GHz min, and I get about 4700 in Quadrant, and I reduced homebutton lag to minimum. Some can't see difference between 1.4 and 1.2 and some can (like me). Works just fine.

MiniCM10 Processor Settings

Hello,
I'm writing this thread to know which processor options would be optimal in our minis. The best settings, which give me the best performance/battery, I've found are:
CPU Governor: SMARTASSV2 (Default)
Min Freq: 19MHz
Max Freq: 748MHz
Undervolt: TRUE
I'm also using Apex Launcher. Which settings are you using?
Note: This are just my results, be careful when you change your processor settings.

Whats the purpose of Undervolting when you have it's max frequency as overclock?

Because it undervolts on every frequency below 600, and his minimum is 19, so when the phone is idle or doesn't need all of the processing power he saves battery
The SmartAss governor is very good at picking the right frequencies for any given job, so it doesn't allways run on 748Mhz, not even when you're using the phone.

That is the same very purpose of SMARTASSV2 to undervolt your device when idle or on sleepmode and overclocks it when on process. So ticking the undervolt wont affect your device because the one that manage the frequency will be the COUgovernor.

The SmartAss Governor only governs the frequencies, not the voltage that the Processor uses. there is a difference between the speed the cpu runs on (Mhz) and the amount of Electricity (Volts) it gets fed
Say Qualcomm has said it needs 5 volts to run at the stock frequency of 600Mhz, then the processor will always get 5 Volts, no matter which frequency it uses.
Undervolting will feed it less than the 5Volts when the frequencies are lower, SmartAss won't do that, it will run the 19Mhz still on 5Volts.
(Voltages are examples, i don't know the exact values, but I know that running on 122 or less will be stable on less than half of the nominal power)

[Q] (Rooted) - Over clocking

Hello forum,
I have followed through the steps to root my Galaxy 5 player and I'm interested in over clocking it for better performence towards games and all around use. Can someone guide me on which application, what speed to set it on, or a break down about the good and bads of overclocking? This would be my first time doing so and I would appreicate the guidence.
Thank you for your time.
You will need to flash a custom kernel. Look in the development section. It will give you easy answers.

There are many applications in google play to help you overclock(OC)/underclock(UC). The most popular ones seem to be Tegrak Ultimate and SetCPU. Both pretty much do the same thing (with a few exceptions one being SetCPU tends to give you a bit more information to look at), however these two you have to pay for. Some free alternatives (albeit you will only get the basic functionality) are AnTuTu CPU Master (Free) and No-Frills CPU Control. These two give (along with the ones mentioned before) you the basic functions to OC/UC, Undervolt, Set the Governor, Set the I/O scheduler, and some other tweaks you can do.
The good thing about overclocking is that it has the potential fix lag problems on your device, make games run smoother, and etc
The bad thing about overclocking is that it makes your CPU work harder (meaning that it could damage it if you OC for very long periods of time), makes your device run hotter, and reduces battery life.
The kernel is the thing that gives you the ability to OC/UC. Most kernels are setup default to OC to 1.2 ghz. But you can go much higher than that. I know with Tegrak Ultimate you can OC to 1.3 ghz, however some people have OC'ed the 5.0 to 1.5 ghz. You must install (Flash) a kernel in order to overclock or underclock the CPU.
This is a list of all the custom kernels/roms for all the Galaxy Players currently out. I believe most have instructions to help you flash a new kernel/rom. Just make sure you are flashing one that is meant for YOUR DEVICE, or you will brick it. http://forum.xda-developers.com/showthread.php?t=1720457
This is from XDA http://www.youtube.com/watch?feature=player_embedded&v=HMdOlxOee0o that talks about Rooting and Overclocking
This is another video showing you how to overclock http://forum.xda-developers.com/showthread.php?t=1720457 (pretty much the same thing for all android devices.
Hope this helps you out.
Tegrak Overclock works fine. Overclocked to 1.3GHz with no problem at all. Needs root and custom kernel.
If you have money buy tegrac overclock ultimate..i use on 1.5 ghz just with tiny more voltage and other fq i undervolted so very good speed and battery is also good.

I use Tegrak Overclock ultimate to reach up to 1.5 GHz. But do you really need a custom kernel to overclock?
I think so, I gave No-Frills CPU control and only got the default my player runs on. I just don't like the custom kernal for the USA Galaxy Player 5 because it doesn't last as long (charging and discharging) as the stock kernal does.

No frills cpu control is NOT overclocking tool..onlu overclocking tool on galaxy player is tegrack overclock.And depends what you want ..slow device but few hours more to last or much faster device but recharging almost every night..difference in speed on GP betwen 1 ghz and 1.5ghz is just huge.

I've already tried many of these application, even NSTools, but Voltage Control is perfect for me.
The reason is that in all these other application I tried, the voltage value you insert is not controlled, you can even go to 5V for example (yes I mean 5000mV), and this does not make me safe!
Tegrak Ultimate should be perfect too, I think, with its bar for voltage control and not an edit box.
