Oh, thinking about writing a new governor are you? Well good luck with that :thumbup: :p

And by the way, as far as I know, no CPU can change frequencies "smoothly", even on the magnificent windows os... ;)
[HTC Desire S] Tectas:
Man really, it isn't that bad at all, yes it isn't perfect and there is still place to enhance, but they are already working on it (see project roadrunner) and are you aware of how hard it is to get the "perfect" balance (even without adding personal preferences). Really, get deeper into it, it does not jump from strict mode to another, with the right governor you get smooth scaling (at least as far as possible), it only jumps, at touch with project butter, the other times the governor scales.

If your not happy with it, flash ics or gb and stick with it, no project butter.

Or switch to Windows phone and stick with the closed platform.

Android needs reading, find the fitting setup for you, play with kernel parameters, system parameters and so on and get what you like to have our even better if you are not happy with what currently is available, invent a "better" governor yourself.
[HTC Desire S] TeddyOFLove:
Definition of Smoothly is hard to define in this case it is more like as smooth as it can get :D. What i am talking about if you atleast read anything in this thread is that governors (curent system) is full of flaws and very battery unfriendly, so it has to be changed by Android/Google (android software developers and cpu and phone makers)
[HTC Desire S] Tectas:
Use conservative, it hits every frequency step at scaling up and down, that's what you wanted ha?

And no they aren't, only you say it, because you have not much clue how you can get your setup right done (or it at least seems that way), they aren't perfect, but no current mobile os is perfect.
[HTC Desire S] teadrinker:
I still don't get what differences you see between android and other systems in this respect.
[HTC Desire S] TeddyOFLove:
Yeah its full of flaws and perfection is not possible couse of hardware and human psibilitie. Thats what i am talkin about here is what i think of these things and i i only asked what others thiink about it. But sadly enough nnone have their own opinions anymore or they simply dont care.

You know thats what forums are about to disscuss things about common intrests (this case Smartphones and stuff directly related to them).

And as for your statement that it isnt that badi would disagree, becouse it is not normal to keep releasing phones with unsolved problems like this. If new phone is released it should atleast fix or tweak those problems or make for example beter battery's.

OFF-topic:

It is common knowledge that for example batterys with better potential and better capacity are already invented long time ago, it is simply that phone makers dont want to spend extra money for battery . Would you sell Your creation phone for 1500$ production cost is 500$ at most. And when you add battery which alone costs 200$ instead of simple old 20$ battery, you get 1500-500+20-200=820$ profit and not 1000$. If you sell 100,000 copies with better battery you would loose 180$*100,000=18,000,000$ :D it is funny how it works they only need our money. Companies that make give or take 1,000,000,000$ a year are ready to "risk" it all at expense of their consumers.
[HTC Desire S] TeddyOFLove:
I dont, couse i havent used other OS phones. I talk about it in generall, and i asked what other members think about CPU handling of other Phones OS compared to Android.
[HTC Desire S] TeddyOFLove:
You know yourself it is not what anyone wants + it is slow. It is only climbing stairs. Jumping from one to other (at preprogramed condition, probably timout like uaually), so it hits every freq but is is as i said just jumping around without concern for what is going on. Just getting preprogrammed condition realised.

UPDATE:

Ohh sry for triple post (should have multi queted) not spammin and will not happen again
[HTC Desire S] Tectas:
Because it's a problem for you it doesn't mean it's a problem for anyone, i charge my phone anyway every evening and i can pass the day without problems.

The thing is you state it like everyone should be pissed, because it is as bad, but that's only your opinion, not only that it's your opinion without founding it one enough background.

And stating to have no own opinion, because I'm not sharing yours is just childish.

About your off topic, yes they want to make profit, that's what they live from.

The reason why current devices aren't equipped with better battery cells is simple, they could build it for sure, but they would need to sell it at a price level no one would pay for such a device.
[HTC Desire S] teadrinker:
OFF TOPIC: I'm beginning to think TeddyOfLove should go into politics ;)
[HTC Desire S] Tectas:
You moaned about smooth scaling, that way you get it.

With the right governor it does not jump around without concern, it scales based on load, yes it's preprogrammed, but still doesn't scale completely up if it's not needed. Or do you want something like an a.i. for scaling? Good idea, take a second device just for scaling the first or get a damn slow device, because of the overhead with worse battery life than current devices.
[HTC Desire S] TeddyOFLove:
I neve said it problem for everyone everyday. It is problem for everyone, but as you say me too charge phone once ~24 hours, and i can use it at medium use(so no problem there). And dont call me childish couse i was reffering to all people that read this thread and dont post any opinion on this matter. You did post your opinion we disscused and it is normal (noone is childish or anything) just all (3 people atm :D) having their own opinions.

Heh :D you should be comedian :D
[HTC Desire S] TeddyOFLove:
Preprogrammed being mostly timeouts and time based scenarios. It is not time that you need is looking at state of devise and adjusting. A.I. would be nice.but its more from fantazy world :D.

P.S. And once again i just point out that i dont moan(or anything close to that.) I just simply state opinion give arguments- you and others agree disagree on some points and give arguments and its goes round and round. If you dont like to read, post , discuss, share, think - then you are robot man (like auto answer machine). And i doubt forums were created so Some Auto-aswer machines (spambots) would post. It was for real interaction and communication. So just stop flaming, and if you dont like something about this thread just as you before did post your opinion and leave(not an order just healthy advise, couse rage of some Forum is pathetic)

BTW how do you delete post if its fail(double post i mean) so you can make it as edit last.
[HTC Desire S] Tectas:
K, sry about the childish, i misunderstood you.

Still back to the roots, check your setup and enhance it fitting to your needs, I'm a heavy user (2 push mail, some gaming, reading, browsing,...) and can pass the day without problems.
[HTC Desire S] TeddyOFLove:
Yeah i thought you might have misunderstand that part :cowboy:. i am android user for more than a year, always experimenting searching new roms tweaks, scripts and so on. But look. Ok you use email browse net and do other stuff on phone but you probably liek me usually charge throught night (when you sleep). becouse there is high possibility that phone will run out of battery next day if you are for example in some boring class and you need some quality game for 30mins lets say :D, correct? All i think is as much as you tweak current system you wont get much better just some changes. So it probably means something should be changed at Software(OS) level and maybe even by phone makers Samsung,HTC etc...
[HTC Desire S] Tectas:
It's not about how the load gets measured, it's simply not true that it bumps up to max completely without any sense.

Man, really.

First you compare apples to carrots, because windumb (sry, I'm an old linux guy) is energy saving on battery yes, but at the same time you lose loads of performance. At a laptop energy saving mode is somehow like an emergency status which you will also get if you underclock your android device, but it's not meant that way, because the common use of the device is unplugged and I'm pretty sure you wouldn't be happy if you lose a quarter performance every time you unplug it.

Second you denounce something present on every smartphone, no matter which os it runs with, but the big difference is you can enhance it yourself by changing configurations, which is only on android possible.

Last but not least, you started this at a time project roadrunner has already got announced, which focuses exactly on that culprit.

I in most common play games when I'm on my way to work ;)

Not completely true, i charge it every evening, but over night it's unplugged.

And yes, after a heavy use day, it probably would run out of juice at half of the next day with the same use. But that's like it is, usage needs juice, simple as that, if you are not happy with it, use a feature phone, if you still want to use the feature richness of android, live with it, it sure will get better over time, but currently it is like it is.
[HTC Desire S] SimonTS:
I've kinda followed this thread the last few days and not posted my opinion on it. I never bother tweaking the CPU Governor settings or anything else - I have been using Reaper for months as my daily ROM and have never felt the need to do so. I don't understand what goes on 'under the hood' anywhere near as well as Tectas which is why I haven't joined in with the technical discussion.

However ... the problem with Android is NOT the CPU, how it steps or anything else. It is perfectly possible to tweak it, change frequencies, undervolt it etc to extend battery life. The problem is the display - pure and simple. I charge my phone over-night, unplugging it at 6:30am when I get up. During the day I use it for a few calls, checking XDA, a bit of web-browsing and normally have about 40% left by the time I go to bed and put it back on charge. However, consistently the display take between 45%-50% of the battery. I have actually tested this once, intentionally, and when I didn't actually use my phone for anything - apart from answering incoming calls - I was able to extend it to almost 60 hours before it started shouting that the battery was about to die.

No matter how much you tweak settings it is not possible to use your phone without the display, so making major savings to battery usage is really a very difficult thing to do. You can't blame Google, Android or anyone else for that - the exact same thing happens on Blackberries (they last longer because they have much smaller screens that nobody actually wants to try looking at anything on), iPhones and Windows phones. IF you use it, then the display is on, therefore the battery is being sucked dry.
[HTC Desire S] teadrinker:
Very true, thats why my old Nokia with a pixelated monochrome display lasted a week without charging, even though it had a worse battery and even if I played games on it.
[HTC Desire S] Tectas:
But you still can enhance it a little by keeping the screen brightness low, for sure not that much, but a few hours you still get.
[LG Optimus 4X HD] judodave:
hello

i have bricked my lg p880 but i cant get it out.

I have tried everything.

Can somebody please help me?

Thanks

Im really desperate
[LG Optimus 4X HD] oktay50000:
tell more

need more info

whats phone situation
[LG Optimus 4X HD] RuedasLocas:
OK, lets do it...

First you'll need the .kdz file. The firmware to flash it. Click here: http://csmg.lgmobile.com:9002/swdata/WEBSW/LGP880/ANLDWH/V10F_00/V10F_00.kdz

Next, the programs, here: http://www.4shared.com/rar/Re4VCOAS/kdz-update.html

Assuming that you already have the LG drivers installed...

1 >>>>> copy the V10F_00.kdz to the folder that you download (kdz-update).

2 >>>>> install "msxml" from the "kdz-update" folder.

3 >>>>> run "Windows Enabler" from the "kdz-update" folder, it should appear an icon on the right/bottom of your screen, if not near the others in the taskbar, you need to click on it and you should see "ON" on that icon.

4 >>>>> run "UpTestEX_mod2_marwin" from the "kdz-update" folder.

On the field "Select type" choose "CDMA - SmartPhone(WM)" (if the flash fails change it to "3GQCT - SmartPhone(WM)")

On the field "Version" (at the left) type "V10F_00".

On the field "Select model .dll" browse and select the "P880.dll" from the "kdz-update" folder.

On the field "PhoneMode" select "EMERGENCY".

On the field "Select kdz file" browse and choose the "V10F_00.kdz" that you download and should be in the "kdz-update" folder.

5 >>>>> with your phone "OFF" and the USB cable connected to the PC, press "VOL-" and connect the cable to the phone untill it turns "ON" in "S/W Upgrade".

6 >>>>> Now click on "Start Upgrade" in "UpTestEX_mod2_marwin". As soon as you see some progress in the log, put the battery on the phone, carefull to don't let it drop.

Wait until the phone reboot by it self and it should be all.

Let us know if it worked or not and, or, if you have any other problems.

Good luck!
[LG Optimus 4X HD] judodave:
The phone boots up but stucks at the lg logo. With 'select type: CMDA (smartphone wm) the log stops at '13:41:32 : 3GQCT : wParam = 2001, lParam = 0'. It never says complete. And with 'Select type: 3GQCT (smartphone wm) it gives an unpacking error.

Its very anoying.
[LG Optimus 4X HD] RuedasLocas:
Forgot to tell you, everytime you need to use the flash tool you need to close it and restart it again.

That unpacking error is because of temp. files. The program unpack the kdz file to another one where is the .dll and the .dz, doing that twice it uses to have that error.
[LG Optimus 4X HD] XperiaPlayer:
What RuedasLocas said is correct however this:

On the field "Select type" choose "CDMA - SmartPhone(WM)" (if the flash fails change it to "3GQCT - SmartPhone(WM)")

Isn't. Keep the phone type set to 3GQCT.
[LG Optimus 4X HD] judodave:
thanks but it didn't work. Still stuck on lg logo without boot animation :'(
[LG Optimus 4X HD] RuedasLocas:
@judodave, try first flash the V10A version.

My first flash went wrong and I was going crazy around the V10C and only after I flash with the V10A I was able to re-flash with the V10F.

Maybe it works with you to... at least I hope so.

Here is the link: http://csmg.lgmobile.com:9002/swdata/WEBSW/LGP880/ANLDWH/V10A_00/V10A_00.kdz

I'll flash mine (later of course) just to post a damn video of how I do it.

Good luck once more.
[LG Optimus 4X HD] judodave:
thanks but didn't work either/ i shall try V10C_00 as of it came out off the box with V10C i beleive. Wish me luck :good:

(edit: I meant V10D sorry. But i will try V10B too.)
[LG Optimus 4X HD] judodave:
nothing works. It wont unbrick :(
[LG Optimus 4X HD] RuedasLocas:
You'll do it. From time to time someone appears with a phone like yours. For sure is something escaping and we just don't figure out what it is.

When we start to do the same thing over and over again, we use to forgot some small procedures.

Don't worry, one of these days you'll make it.
[LG Optimus 4X HD] judodave:
Thanks for your help. I think I am going to send the phone to lg and hope for the best. I need the phone now. So waiting is no option. Agian thanks for your help.;)

step 6:- then it will show ur phone connected but it may say ur phone as already updated software etc, but dont worry it will update it then leave it it will start downloading firmware and once its over phone will reboot normally, u got ur phone back, working
[LG Optimus 4X HD] bajoel_cilik:
Thanks.. It works

Thanks.. it works. I just upgraded my lg p880 from v10e to v20a two days a go. Then i rooted the device. Works for two days, then it stuck at boot logo after I restarted the device. Do not know why. So far has been disappointed with the battery performance and the sound quality of this device. Hopefully the new v20a can help improve even just a bit:good:

Help me

Hy!

It seems to me you are an android literate, therefore I ask for help.

My problem:

I wanted to install a custom rom, but before I wanted to install the cwm recovery. When I finished the process and I clicked on the installed recovery apk file to it has my phone started into cwm recovery mode I stucked on the boot screen. I have tried to download a p880 kdz file for firmware update, but I can't find it nowhere.

The mentioned lg firmware download link no longer work anymore. I can my phone place sw upgrade mode but without firmware it doesn't work.

Please help me if you can.

Thank you in advance!

Sorry for my bad english. I hope you understand what I want to.

Gabi from Hungary
[LG Optimus 4X HD] kessaras:
here all yours. its the old version. the guide to flash using kdz sais its the pc suite. this means inside pc suite u can download latest version of support center. close it when it opens up automatically and inside C:// in your hard disk you will find the files of the newest version of support center to flash the kdz file. any version since 2012 will work.
[LG Optimus 4X HD] flower78:
thanks

Thank You!

At last I downloaded the right kdz file successfully and my phone is working again.
[LG Optimus 4X HD] iHDscope:
Hi, I'm new to the whole xda-forum-thingy and I basically did the same thing like flower78.

I installed an older version of CWM touch recovery on my p880 (4.1.2 and V20b) and when I wanted to boot into recovery it simply stopped after the LG-logo and the one of my provider. I already tried the guide UpTestEX_mod2_marwin.exe but after saying "Start fn_StartUpgrade" and "Extract kdz file" it always stops working and windows gives me a message that it stopped working and it closes afterwards. I can't acces the S/W mode without my battery, although people said I'd need to remove it and once the protocol started, I had to put it back in.

I also tried LGflash Tool.exe but it didn't work either since nothing would happen after saying ready.

Hopefully, someone will help me.
[LG Optimus 4X HD] kessaras:
if the only problem was the recovery then why didnt u just re-flash another one ? :rolleyes:

also the pull out battery trick is kinda old and doesnt work for everyone. do a reboot and keep hitting home button ( dont hold it ).

about the windows error message , i dont know. its your windows problem. the lg support tool is running when u do it from lg pc suite ?

if yes then just go in C:// in there u will find the lg support center that the lg suite auto downloaded and worked for u.
[LG Optimus 4X HD] iHDscope:
I do not how to do it since I cant even boot my phone. It stucks after the LG logo and I cant do a factory reset (pressing vol down and the power button lets a small red text appear([lg security]error: boot image signature). Appearently, my bootloader was locked when I flashed the CWM, although it was supposed to be unlocked.

It once worked yesterday (I do not know why it worked) but I could not install any USB driver since there was nothing in the window. Now, it does not run anymore. I always get the information that I am supposed to check my internet line and to execute the program again. I try to use the R&D test tool but it says: port or device not found

I assume that I get this message because I cant install the b2cApp Setup.exe...

---------- Post added at 03:25 PM ---------- Previous post was at 02:35 PM ----------

Nevermind. I just used another PC that didnt have anything to do with lg and did the whole procedure and it worked. It probably had something to do with the drivers but Im not 100% sure. Nonetheless, thanks for your help.
[LG Optimus 4X HD] kessaras:
yea it had. to flash the kdz u need usb drivers and to unlock bootloader u need adb drivers. search and read before u do anything

[LG Optimus 4X HD] kessaras:
everyone does the same mistake. again and again... everyone wants a custom kernel and rom without understanding what that is and how to achieve it. now this guy has the same problem , im sure. he tried to install cyanogen recovery without unlocking the bootloader. so he failed. so he needs to reflash the stock or unlock the bootloader to reflash the cyanogenmod recovery. either way , i will say it again , so that everyone that happen to try to go from stock to custom , read it. READ and STUDY before u do anything.

if u dont understand and dont watch some video to really get the idea of what is root, bootloader, recovery , kernel , rom , then u are doomed. u will spend weeks and months of the one and only lifetime we have , over something that actually is 10 minutes to do.
[LG Optimus 4X HD] momo95:
I remember that first time I learn took me 6 hours to do all that. What I'm gonna do is starting with flashing lgkdz, after that root, unlock boatloader, install recovery than flash ROM, gapps if needed and kernel if needed.
