you need to wait a few hours before you can say anything about battery life ;) your phone has to re-build all caches, dalvik caches, and so on ;)

before you can _really_ say something about battery, you should wait 2 or 3 charging cycles ;)
[LG Optimus 4X HD] leortez:
Im currently using v8 of your kernel, its working quite alright with rc1cm10.1.3, my comparison is with iodak v7, so far this kernel seems more stable than iodak. I'm using on demand governor and sio scheduler. Battery seems to be improved, no heating felt by normal use, seems pretty solid in its behavior. Thanks for your work!
[LG Optimus 4X HD] baxtex:
Okay. :silly:
[LG Optimus 4X HD] gingerboy92:
my phone just died, it's not coming back to life, even navigation key light doesn't light up anymore, i guess the motherboard i burned. i didn't overclock, but i did undervolted it. i guess changing the voltage too much can destroy the phone. lesson learnt T.T

ps: not related to this thread, but can anyone tell me if is there any way for LG to know that i have unlocked the bootloader with the phone totally dead?
[LG Optimus 4X HD] FunkyRasta:
Remove battery, plug usb cable connected to computer connected with pressing either vol up or down , repeat the same with battery. If it doesn't boot, it is dead.

Kernel and undervolting just simply can't burn your hardware, this isn't 80's hackers movies ;)

Probably you got dead nand chip, so LG won't know anything.
[LG Optimus 4X HD] gingerboy92:
i tried plugging in the charger, both with the battery in, and without the battery, but no sign that it's coming to life.

by burned, i mean short circuited the motherboard, or whatever is it called. i don't know the exact term, used whatever in my mind now. :P so, it's better if the board is totally dead rather than alive-but-not-useable. got it. going to figure out a way to fully kill the motherboard if they are not accepting my phone. good luck to you guys playing with the voltage and overclocking. :D
[LG Optimus 4X HD] FunkyRasta:
No no no no no no and again no!!!!

Connect to COMPUTER not charger.

Secondly YOU COULDN'T made this by overclocking and playing with voltage!

Impossible! Do not spread misinformation!

To do shortcircuit you must manually connect two points on motherboard.

And UNDERvolting extends lifespan of device. Even if you OVERvolted you can't just raise values ridiculously high enough to kill device.

Your case is probably just generic production flaw which resulted in your motherboard/cpu/memory dying.
[LG Optimus 4X HD] penguin449:
Edit: can you get to recovery? plug it in and hold power and up for about 5 minutes max
[LG Optimus 4X HD] profyler:
Guyz, i dont think my fastcharge script is workin, i made the script

#!/system/bin/sh

echo "1" > /sys/kernel/fast_charge/force_fast_charge

and saved it in system/etc/init.d

i does not look like its charging faster.

Did i missed something ??:confused:
[LG Optimus 4X HD] gingerboy92:
misinformation? i'll trust my personal experience rather than your words. i had 2 devices before(nexus s, galaxy nexus) that died after a few minutes of overclocking/overvolting. overvolting/overclocking can kill your devices, whether you want to believe it or not, it's up to you.

---------- Post added at 04:14 AM ---------- Previous post was at 04:11 AM ----------

did you changed the permission of the file?

---------- Post added at 04:20 AM ---------- Previous post was at 04:14 AM ----------

nope. totally dead brick. the board is fried i guess. nevermind, going to lg service center tomorrow morning. don't want to spam the thread any further with my totally unrelated problem. word of caution to everyone, be careful when you play with the voltage and clock speed, down is fine, careful when going up.
[LG Optimus 4X HD] laufersteppenwolf:
yes, you can kill your device by Overvolting, but not by overclocking. when you OC, what does the phone do? it highers the voltage ;) and that can kill a processor. BUT not using this kernel. tegra 3 processors can handle voltages even above 1.55V. and the max value you can go on custom kernels on xda is usually 1.237V, 1.25V (iodak) and 1.3V (mine). but these values are only manually reachable ;)
[LG Optimus 4X HD] gingerboy92:
is it possible to kill the phone by overvolting the lowest frequency too much? i just noticed one thing, this is my init.d script

echo '737 750 800 850 875 912 950 975 1012 1050 1100 1125 1175 1225' > /sys/devices/system/cpu/cpu0/cpufreq/UV_mV_table

as you can see, i did something really dumb, i mean, really-really dumb. the order is wrong, according to the script that i used, 102/51mhz is using 1225mV.
[LG Optimus 4X HD] laufersteppenwolf:
hmm, it could, but i honestly don't think so...

maybe it's also just a coma brick, and no hardbrick ;)
[LG Optimus 4X HD] gingerboy92:
i hope that it's not so, don't want it to come back to life in when lg's technician try to turn it on, then they will know that i've unlocked the bootloader, and the warranty will be voided. :P any idea on what else should i try before going to the service center? if none, thank you very much for all the information you have given. ;D

edit: hey, i connected the phone to my windows pc(was using linux), the phone was detected as apx(with no drivers), can you direct me to a thread where i can find more information about how to get the phone back to life? i'm searching as i'm typing.
[LG Optimus 4X HD] theofficialpimp:
Anyone tested v8 on Stock v20a yet?

:sly:
[LG Optimus 4X HD] someth1ng:
Try kdz flash? If that doesn't work...then it's probably over.
[LG Optimus 4X HD] Zhus06:
does this kernel support loop devices? if not, anyone knows which one or if any does?

bcs when i do "fgrep loop /proc/devices" i get nothing..
[LG Optimus 4X HD] gingerboy92:
i'm twice more confused. the phone is stuck on apx mode suddenly after it shutdown without warning(now, the shutting down part that i think was related to the overclock/undervolt). as to why does it booted into apx mode, and are stuck in it, i don't know. i have been searching, but i can't find enough information about it.
[LG Optimus 4X HD] JoinTheRealms:
Apx mode would allow you to run NVFlash commands (for lowest level access to hardware, even below bootloader) but afaik LG dont include NVFlash binaries with there bootloader, making it impossible.

Although since the device IS running in apx mode thats a good sign, possible damage to emmc but thats wild speculation:)
[LG Optimus 4X HD] laufersteppenwolf:
AFAIK we can't use APX mode...

try to pull the battery, open the kdz flasher, press vol - and plug the usb cable - then hope for the best and try to flash a stock kdz..

if it doesn't work, i'm afraid you hardbricked your device...

now, to everyone, please stop this massive ongoing OT i say nothing against [MENTION=4065751]gingerboy92[/MENTION]'s problems, but all other stuff, please stop.

else, i see me forced to close this thread for some time...

thanks in advance :)

ohh, and BTW, [MENTION=5102939]penguin449[/MENTION], i've never been banned :rolleyes:
[LG Optimus 4X HD] profyler:
well, i put the permission like the two other stock scripts:
[LG Optimus 4X HD] laufersteppenwolf:
could it be reset by another app during boot?

try to run it manually and see if the file flag is really getting changed ;)
[LG Optimus 4X HD] Flying_Bear:
Ill run kmsg tomorrow, for now some additional info : it doesnt throttle as soon as i start asphalt, but around the time main menu has loaded throttle kicks in. If i keep asphalt as front process, it will stick to 1ghz,but if i "alt tab" to another process, it might jump to higher frequency untill i tab back to asphalt (happened with nfs too). Kinda seems like if i run 3d app, it throttles down
[LG Optimus 4X HD] profyler:
by running manually do you mean, see in /sys/kernel/fast_charge/force_fast_charge if the value changed to "1" ? if yes, than yes, it really changed. before the script, after reboot it was always reset to "0", meaning the script is working.

I didnt understand what you mean by "file flag is really getting changed" :silly:
[LG Optimus 4X HD] laufersteppenwolf:
THANK YOU! :D i think you just gave me the right tip ;) :D

That's exactly what I meant ;)
[LG Optimus 4X HD] profyler:
hmmm, so, it should be working but its deffinetly not. any other idead, guys ?

the fastcharge should work on ac charger and usb charger ?

EDIT: if you change fastcharge to 1 (activate), you loose MTP usb...dont know if its a bug...
[LG Optimus 4X HD] Flying_Bear:
i guess we'll figure it out tomorrow, forgive me that i didnt provide logs tonight, got my bachelor of arts title today, so its more beer talking than me, but hey, i guess the best inspiration comes from being buzzed :D

Anybody having trouble getting gps locks? I can't seem to get a lock on cm10.1.3 with werewolf kernel. Any suggestions?
[LG Optimus 4X HD] EB20XY:
lock comes extreme fast an good. (on CM10.2 with this kernel)
[LG Optimus 4X HD] laufersteppenwolf:
well, you could add a debugging-line to your script ;) like creating a file on your sd, and echo'ing "fastcharge activated" or something ;) so you see if the script is getting executed during boot or not ;)

and no. fastcharge "fakes" and ac charger, no matter how you are charging. meaning: even if you plug your phone into your PC, it's getting recognized as an ac charger. that's also why there is no mtp ;) and no, it's no bug :p

np, i ran many logs myself, but for some reason i've seen nothing :eek:

but your "3d" word gave me a good hint i guess ;)
[LG Optimus 4X HD] tool_king:
Congrats, mate! :good:
[LG Optimus 4X HD] wajahebat:
Good day all...Ive tested this kernel since last two days and was shocked that it includes Smartassv2 govn...

But then i found out that op's smartassv2 seems weird and somewhat drains my battery a lot...Ive altered most of the govn settings

like ( ramp_up_step/down_step/awke_ideal_freq/sleep_ideal_freq/downrateus/uprateus ) but still it doesnt behave like it should..

When charging, cpu freq directly pushed up until 1Ghz and stays there until i unplug....But when i leave the phone unplugged, its stays

deepsleep just nice...But it doesnt touched any unround freq like 620mhz/540mhz...Charging takes a long time as the cpu stays at 1000mhz all the time Its all happens in Smartassv2 govn...Now im stick with Wheatley govn which performs best right now...

Thanks and i hope this observation helps u;)
[LG Optimus 4X HD] Omario-242:
Wheatly is the best for me as well. The charging is really fast and if I don't play anything or heavily use it, I underclock to 1300 MHz and it's still very responsive and fast UI :) I love this kernel since the beginning.

You are awesome [MENTION=4716493]laufersteppenwolf[/MENTION] :)

EDIT: Forgot to mention, that the battery life with underclocking and quite high internet use (XDA, Whatsapp, Facebook, 9GAG) is really good. 7 Hours of usage and about 50 percent drained.

Sent from my LG-P880
[LG Optimus 4X HD] profyler:
Thank you a lot for your help. I thought fastcharge was also for the ac charger that is much slower on CM than stock. Thanks
[LG Optimus 4X HD] wajahebat:
How did you get that 7hrs screen usage dude?
[LG Optimus 4X HD] dev0lver:
That is probably drain of battery, not screen on :)
[LG Optimus 4X HD] wajahebat:
Okay just finished testing Wheatley governors for one day...My observation was, it enters deep sleep just right about 5 min after i lock screen...

But dont know why it drains such a lot of batteries even in deep sleep mode...But performance are all okay....Not sure what was the caused of this...Will test more today
[LG Optimus 4X HD] Omario-242:
It's not screen on time. Just usage time and I use it about every 5 mins so nearly no deep sleep. But the drain is ok for this time :)

[LG Optimus 4X HD] baxtex:
Well have used latest version now for one empty battery and one full and i'ts quite good. Don't have much wakelock anymore. However I have noticed that it takes significally longer too boot the phone? It's showing the LG logo for abou 15 seconds before starting to boot the os. :confused:

Not a major problem of course but still. :)

Then it capped itself to 600mhz all random. Rebooted and it disappeared.
[LG Optimus 4X HD] Omario-242:
For me the frequencies work perfectly, which rom are you using on top of WWJB?

Didn't notice the longer boot time either but I will have a look at it next time :)

Sent from my LG-P880
[LG Optimus 4X HD] laufersteppenwolf:
i think i can tweak the time till deep sleep a bit more ;)

i'll see what i can do ;)

hmm, it shouldn't take longer to boot... are you sure?

about the freq, a kernel usually can't cap itself to a freq (except for thermal throttle ofc ;) )

could it be an app causing problems?

@all, i think i've found the cause of the 1GHz throttle issue, stay tuned ;)
[LG Optimus 4X HD] Flying_Bear:
here it is. started continuous log dump, i opened asphalt (at around 19:24), all cores were running at regular speed (up to 1.5ghz), untill i went to race. sometime while loading the race, it got throttled down to 1ghz per core, making it unplayable. also, i had to kill the process with back button, as i couldnt quit the game normal way for some reason. after i exited the game, i waited till processor could go up higher than 1ghz and i stopped the logging. here's the result, hope you can find what could be wrong ^^
[LG Optimus 4X HD] laufersteppenwolf:
just like my logs ;) :D

you can check yourself, whenever "boost load shaper" is triggered, it gets throttled. but if it's off, 1.7GHz is working just fine ;)

<4>[13:09:03 19:26:30.457] boost load shaper triggered!

<4>[13:09:03 19:26:30.597] boost load shaper off!

so, any way to "fix" it? :D

i'm not sure what boost load shaper is for

On screen time has increased but Deep Sleep can do better

But on wheatley + row 102 - 1200 Mhz ... the phone heats up in about 5 min doing nothing but checking mails.... not reaching throttle temp and all but I still expect it to be cooler while casual use...

Anyway been running now for some days here is my report with interactive and noop:

"wlan_rx_wake 6m

8H deep sleep

32m 102mhz

20m 600mhz

But muic lock don't seem to drain battery: http://xdaforums.com/showthread.php?t=2164352

But my phone was spending almost one hour in 102mhz and 600mhz whcih is probalby why it drained battery.

But I have seemed to narrowed down my previus problem though.

If i choose t reboot via the reboot option in the powermenu, then phone will get caught in a bootloop, but if I turn it off and then start it, it works like normal.

In my previous post, I said Deep Sleep could be better. I was using Eternity's 10.2 ROM

Installed Paranoid Android 3.99 and installed this Kernel again. The deepsleep is amazing.. 6hrs with 0% battery loss! Mobile Data is working as it should, no issues.

Problems... On wheatly + row... CPU speed wont go below 102MHz.. Temp throttle is very severe while using wheatley (aggresively reduces speed to 475 and slowly increases to 1000MHz)

As reported earlier, the temp rises to 34C in just 4-5 min of 2G + checking mails...

What combination of governor and scheduler are you using??
[LG Optimus 4X HD] laufersteppenwolf:
alright guys, it took some time, but fixed version is coming soon ;)

Also, please test the camera performance during recordings. it should be better now ;)

About deep sleep, it sleeps like a baby for me... no problems ;) maybe check your apps/settings

And about smartassV2, it was buggy from the beginning... as an example, it was working fine for [MENTION=5106530]FunkyRasta[/MENTION], but not for me...
