i9000 goes off

Hi,
i have an Italian version of i9000 with jf5 firmware.
I have upgraded whit samsung kies my firmware.
now i have
pda xwjm3
phone xxjm2
csc itvjm1
now sometime my phone goes off
anyone have the same problem?
i read that this is a bug......

You read its a bug? Of course it's a bug.
It's either a bug with the firmware or with an application. I had the same problem when using SetCPU.

i have setcpu me too.
so the problem is this app?
just uninstall it?

I experienced it (no response completely unless I reinsert the battery) when with lag fix and GPS on, regardless eclair or froyo ROM.
then I reflashed and turned GPS off for most of the time on my 2.1 lag-fixed ROM, the problem seemed not to trouble me any more. I have also underclocked my CPU with "Overclock Widget" to 800/400 MHz on screen, and 400/400 MHz offscreen.
I have a feeling that the problem was due to GPS or due to the 0513 pit, but I'm not sure - so far it's been okay so I bother not to break it for tests.

SetCPU shuts my device down... out of nothing...
i uninstalled setcpu and never happened again

Slightly off-topic but... That'd actually be an overclock if I'm reading those numbers correctly. The default frequency is 1000/100mhz with a conservative setting, meaning it'll try to be as low as possible more or less. What you've done is set min-frequency to 400mhz, which in my book is an overclock from the stock 100mhz.
Back to semi on topic... SetCPU is known to cause problems on Galaxy S, and likely other devices aswell. Most problems has been more specifically caused by using ondemand setting when setting up profiles - for some reason the phone doesn't handle this setting well when it wakes from sleep.
I'm pretty sure I managed to get it working more or less flawlessly with an screen off profile at 400/100 with Conservative setting, though I reflashed shortly after those settings so never got to test it properly. Regardless, they might work if you want to mess about with it.

I had a similar problem with JM5 and SetCPU.
Removed and it didn't happen again.

The way to have SetCPU working is to do the following:
Scaling: conservating
Freq Step: 100

Great!This work

I don't use setcpu but I have this problem in my two SGS. Using m5 and m6..

[Q] SetCPU Randomly Rebooting One X?

Hi All,
After being a long time iPhone user i recently purchased htc one x, as a result my android skills are almost non-existent; so please bear with me.
I managed to flash clockworkmod recovery and rooted with SuperSU with no issues.
Purchased setCPU after reading the reviews and enabled. However the phone would reboot randomly a few times a day. Ususally when the screen was off.
After disabling setCPU there was no rebooting issue.
Has anyone got this app to work on the OneX, and if so which settings did you use?
Also has it been confirmed to work with all 4 cores?
FYI I had the following profiles setup.
Screen Off
Freq:640Mhz-51Mhz
Gov: conservative
Temp > 44.5
Freq:880Mhz-51Mhz
Gov: conservative
Battery < 30%
Freq:1000Mhz-51Mhz
Gov: powersave
Charging Any
Freq:1500Mhz-51Mhz
Gov: ondemand
Please note these profiles are based on no evidence, just on what I estimated to be about right...
Cheers

I did not start using SetCPU on my phone yet because it's not rooted, but first I would check if SetCPU doesn't require some kernel support? and if that's implemented in the custom ROM you're using? (if it's needed, I'm not sure).
Or maybe SetCPU needs an update to properly support our phones?
That Temp > 44.5 Profile, wouldn't that interfere with gaming? I have never used Temp profiles before (is it really needed?), only the other ones, like battery and screen-off and charging.

my one x has unlocked bootloader, recovery and root. I was running into some serious intermittent lagging issues, the phone in any app would just stall for 5+ seconds. after hours restoring after failure , it came down to the problem that using ANY cpu controll app, messed my phone up... BADLY! it seems at the moment (im assuming) apps like setcpu and cpu master are not quad core ready...

thanks for the responses guys.
I guess ill just wait until one of the devs can confirm this as working...

The reason is simple. We don't have rooted kernels yet. Until then stay away from messing with CPU speeds or under volting. Etc.

DO NOT mess with your CPU speeds yet. Undervoltage is causing reboots!

the software is not up to the hardware capability, i dont think the cpu control apps can handle quad core yet. and there is a lot of apps (esp. games) that lag a lot, and amazingly the cores are too lazy to work... im hoping for a better kernel that will address this issues.

If you want to at least see what's going on with the cores, I can confirm that Tablet CPU Usage Monitor works on HTC One X
It shows 2 icons in notification bar, each icon showing usage of 2 cores. Not sure how accurate it is, but so far had no problems with it and it seems to be reporting correctly. Developer is working on single icon with all 4cores in it, to save space.

I had the same problem, but if you delete your profiles you won't get reboots.
I'm just running default profile Max: 1500, Min: 760 Ondemand gov. and it has been a straight line for 6 hours when I was sleeping and no reboots.

I was having that problem too... In my opinion, I don't think that the phone can handle the Conservative governor setting. I set my governor to Interactive (On Demand works too)
Right now, I have my profile set to 1000mhz max and 475mhz min, with screen off profiles set to 475mhz max and min. I have not had any problems with the phone rebooting at all since setting those freqs. (And I don't want to quite go any lower yet). And I have it Set on Boot.

im now using rooted HTC One X(HOX) and installed RD-MIUI ROM quite sometimes. my kernel is still in stock. Im using setcpu and NO random reboot happen like what you have said. Yet, i am still confuse whether setcpu is good for my phone. based on my review, in the leading rom developer thread they not mention setcpu for their choice. they play alot with kernels to govern their hox cpu-s. could anyone do some comment.

[Q] [CPU] My CPU Speed automatically goes down to 810Mhz

My CPU Speed automatically goes down to 810Mhz on all overclocked kernels.
Even in CM10 kernels,
It happens in between while I play a game or so.
Even if I install Kernel with only GPU overclock, it still happens.
But never happens on stock kernels. I have to manually increase the CPU speed by setCPU.
Any Solutions for it Guys?

Moved to Q&A

Try to use Kernel tuner, and normally the device uses 810 mhz too cool down...

Used kernel tuner but still the same result, it goes to 810mhz even if the phone is not hot (just homescreen) and when i increase it, it remains at max even if i play games and make it hot. but after some time (say 15 or 20 minutes) even if I am in standby mode the cpu goes down to 810Mhz. previously at some point it was 1134Mhz.

Guys, anyone with some help. It has even started to occur in Complete stock ROM. (flashed the ftf on locked bootloader, still the max cpu spped drops from 1.5 Ghz to 810 Mhz, some times both cores)

I had the same problem but i discoverd that the Battery saver pro causes that problem for me. If you use the seme app untick control CPU frequency.

It is actually a built in security feature of our phones which gets activated when temperature of phone goes high . At least that's what I know .

[Q] CPU Problem

Hi, I have flashed Legacy Xperia 4.4 KK ROM and I tried everything but my CPU always works on the highest frequency, even with low frequency settings it works lag-less(so I figure out it is on the highest frequency even when I set max frequency to 300Mhz). I tried changing the governor but didn't work, flashed an official ROM and re-flashed the KK ROM but it didn't help either... even flashing different kernels didn't solve my problem...
Can anybody help me?
This is really Important.... my battery dies every 5 hour... please help me...

Which power plan do you use, sounds like you use perfomance. Settings>Perfomance> switch to balanced power profile.

I tried changing but didn't work...... I think i should migrate to stupid 4.0 Stock ROM.....

Big cluster freq. staying at 2361

As the title says, I have this problem where the big cluster frequency stays at 2361MHz and doesn't drop down to its idle frequency. It occasionally goes down to about 2000MHz, but rises back to its max frequency within a second.
I tried clean flashing OOS 5.0.3 (zip from OP website), I'm not rooted, no custom kernel (all stock basically). It seems to happen after a few hours and not as soon as the device is turned on.
I'm wondering if it's a kernel problem/bug or something else (play services for example). I'd really like to know if anyone else experienced it and if anyone got it fixed.

are you using a custom kernel or root?
if so download elementalx or any kernel editing tool and change the cluster back to 300mhz
i find i have to do this for the cluster to scale back down

You can try New Kernel by @jgcaap.
It's probably the best kernel for this phone with amazing performance/smoothness/battery.
In the latest build the idle freqs are back to normal after OnePlus mess/faulty optimisation in OB2.

If your CPU doesn't idle it can also be an app running in background and hogging cpu time.
