So if v2 boots is the new gsm data modem driver that is causing the bootloops :) Thanks for helping me pin point the bug. I will release a new version of v1.99 with revised driver and if it boot loops too is back to lge 2011 version until i get the phone.

i have flashed v2 kernel, and the phone neve going to deep sleep mode, i have xms_baseband wakelock, so what you recommend new boot.img into 1.8 kernel zip?
[LG Optimus 4X HD] Demetris:
Any zip minus the 1.99 will do :)

Στάλθηκε από το Barnes & Noble Nook Tablet μου χρησιμοποιώντας Tapatalk 2
[LG Optimus 4X HD] donkanmcklaus:
and you think that xms_basebans wakelock is related about the new gsm drivers that you used for 1.99 version?
[LG Optimus 4X HD] Demetris:
New V1.99 uploaded with revised gsm data modem.

Same link in OP.

Test and report.

Thanks
[LG Optimus 4X HD] Kanad:
Sorry for remaining away for quite a some time .... The new fixed kernel v1.99 in OP boots properly :) enjoy...

Thanks but no luck.

first boot after flash, no mobile data.

reboot and flash cache an davlik, no mobile data

try to search network to force register. unable to search provider. (usual i can see the four provider in my country)
[LG Optimus 4X HD] Demetris:
Sorry but i have to ask you to recheck after a last minute change :)

https://github.com/Ntemis/lge-kernel-p880/commit/a9b4e83ed250dbf589d15c1f8314bac0982fe28b

So re-download and re-flash and re-report and re-make me happy with good news :fingers-crossed:

Edit

Post #2 Wifi firmware update ;)

Any feedback? :)
[LG Optimus 4X HD] masmoe:
Network and data still not working.

Wifi workiing but very slow.

[LG Optimus 4X HD] Demetris:
He replaced the gsm data module from my previous data working kernel :)
[LG Optimus 4X HD] ilan_75:
OK. Will waiting patiently for your update with the new GSM module.

Fyi, i will not try the new wifi driver. I don't know how rolling back if something going wrong.

Can you explain to us what is the new 900mhz? I think is not for the gpu(to high). And didn't find it in tegra overclock for the cpu.

Thank you for your hard work without device.
[LG Optimus 4X HD] Demetris:
This i think is more clear:

{ freq_table_300MHz, 0, 1 },

{ freq_table_900MHz, 1, 1 },

{ freq_table_1p0GHz, 2, 8 },

{ freq_table_1p3GHz, 2, 10 },

{ freq_table_1p4GHz, 2, 11 },

{ freq_table_1p5GHz, 2, 12 },

{ freq_table_1p7GHz, 2, 12 },

As you can see before 900mhz our cpu had to go from 300mhz to 1ghz :D

I added a nice middle man in between that big frequency change ;)

Hello 900mhz!:cool:

How is this kernel performing compared to iodak v6 and stock JB kernels ? Batterylife ? gaming ?
[LG Optimus 4X HD] masmoe:
I am not gamer. But for daily working (mobile data / wfi on, messenger, email, phone) it is rock stable, smooth and battery friendly.

Just try yourself, it is only took 5 minute of your time...;)
[LG Optimus 4X HD] Demetris:
Am working hard 8,9 hours a day now for next v2 version, probably will be done tomorrow night, i hope :) :fingers-crossed:

What is best app for monitoring CPU performance/tweaking and where i can see all things related to my CPU and GPU (min-max clock speed - how many cores current kernel is using and etc..)
[LG Optimus 4X HD] donkanmcklaus:
i use perf monitor and cpu spy
[LG Optimus 4X HD] dimi89:
[MENTION=219347]Don[/MENTION] thank you. I tryed SetCPU and TegraOverclock and i SetCPU dont show how many cores are set by kernel to run and i am little confused by TegraOverclock app.... I will try this two you mentioned.
[LG Optimus 4X HD] LamerDuck:
i am very curious how your kernel performs, as you dont own the phone.

would be funny if its better than all these kernels from the people who claim to know their turf.

installing now^^
[LG Optimus 4X HD] masmoe:
Use links from Varadium. Link in first page not updated I thing because Demetris still focus on developing V2.00.

Try it, it is very stable and smooth.
[LG Optimus 4X HD] dokii22:
Installed first CM 10.1 then Optimus Prime kernel,I just want to ask that I did install hime 100 %.

When I go to phone info,I get this

Kernel version

3.1.10-OPV1.199-

demetris@Athlon-M5A78L#1

Cause it has similiar name as CM 10.1 kernel...
[LG Optimus 4X HD] Voltaine:
Yep, it's definitely installed on your phone :good:
[LG Optimus 4X HD] Demetris:
So a few words from me about status update.

Most of my work done is deliberately trashed as i was mixing sense and aosp code to make it possible to use tegra4 drivers.

I ended up in a situation that my commits for fixing compile was more that the new code it self :)

And i realize i was making huge steps without even the device, so scrub and re-begin.

I like to keep the code clean and it was getting to be a mess.

Device: I have the device at last, i got it today. Am on 10E ICS 4.0.3 and i have plans for tomorrow to jb it and unlock bootloader, i hope :)

So what about V2...hmm ok here it is

I make a few big steps :D or huge steps lol

1st is the sound i make it possible to support 24 and 32bits audio code was only using 16bit, now is 16/24/32 and also the huger of the huge and the one am little bit steptical is the new memory timings i have implemented :)

We now have Endeavoru V2 aka HOX V2/PLUS memory timings! This might be good but also bad as LG seems to have used dual memories Rev3.2 and not Rev3.2 aka Rev3.1? Rev3? who knows actually, what was it? Lets share the mystery. Anyways, what might be the side effect am afraid we will have is this:

On some devices the new timing will be awesome or shall i say awesomeness to its limits and just maybe on other devices instability and hard reboots and who knows, it could be also not bootable kernel.

So that’s why i want to take it like baby steps for now.

Thanks for reading. :D

I wont be making another thread for the newly released kernel it will be uploaded very very soon until then may the force be with you! :cool:
[LG Optimus 4X HD] milossimon:
V2 booted and worked for me..mobile data also works :)
[LG Optimus 4X HD] mario.gacv:
Booted fine here too :)
[LG Optimus 4X HD] JoinTheRealms:
Just to let you know the kernel boots fine, I'm on revolt atm. Very smooth as usual, the issue I'm having with your kernels is it won't sleep. Over night it loses about 10%. I'll see how v2 is;)

I very much appreciate your work, can't wait to see what you got next for us:fingers-crossed:
[LG Optimus 4X HD] GRG13:

V.2.00 working excellent as usual

By the way, could you explain about "Endeavoru V2 aka HOX V2/PLUS memory timings"? What kind of benefit to implement it? Is it Boost performance or anything else? Is it benefit for game performance or regular daily use?

Sorry for noob question. :D
[LG Optimus 4X HD] eric1116:
V2 works perfect with LiquidSmooth ROM. I am using conservative governor, it's still acceptable responsive but much more battery friendly. even when I run subway surf the conservative governor is still all right, no lag at all. very good job. :good:

Cannot say much to the battery usage, will report this later after using it today

Is there a way to undervolt with this kerel?

thx for your genius work

regards
[LG Optimus 4X HD] dokii22:
Hy I think you put a lot of effort into this kernel,I dont mean to disregard you,I think it's something wrong with my phone.

So basically I combined CM 10.1 with OP kernel,done everything and I got this battery life after 15 hours.

I think it's worse,even worse than stock rom unrooted and I dont see why.

CM 10.1 is more battery life optimized and with OP kernel I should get far more battery life than this.
[LG Optimus 4X HD] tool_king:
You obviously have a really bad radio signal, that seems to drain the battery a lot. By the way, you should install BBS to explore the cause of your issues.
[LG Optimus 4X HD] dokii22:
I never thought about that.

I live in area between border with Bosnia and Herzegovina and have a really bad provider so every phone struggles with signal and often goes into roaming.

What's truly interesting,I get 3h 38m of screen on stock rom,and display there drains only 12 % battery ( nearly same setting,Auto and about 50% on slider ) and here it drains 50 % :confused:

How so ?

Here are screenshots.

dont mind charging,it was on car charger ( chinese ) while using Ulysee speedometer Pro so basically it drained battery than keeping on same level...
[LG Optimus 4X HD] disadjusted:
That simply means the other's power consumption (cpu, signal, ...) seem to be heavier under stock. You have to see the relations :)

But this is only a calculation, not based on real values...

Sent from my hands using my brains
[LG Optimus 4X HD] Demetris:
what tool_king told you is correct.

You can see from your stock rom pictures that you are most of the time at 1 signal bar and if lucky 2 bars.

That consumes battery, and in cm10.1 that hasn’t got lge's proprietary battery saving tricks in code, what you experience is normal.

What is the resume? My kernel has nothing to do with your problem as is clearly also in stock kernel too, it just been treated differently with lge battery saver tricks and isn’t so obvious.
[LG Optimus 4X HD] @non4:
Everybody does a stock version of their kernel. Now you have the phone you need to do this to compete! :P
[LG Optimus 4X HD] Demetris:
Code is on my github be my guest :p
[LG Optimus 4X HD] Pesach85:
You are doing a great job man, i followed your codes on github and never seen a so updated kernel for LG :)

I'm merging the codes with werewolf kernel to do something but the way is still long :/
[LG Optimus 4X HD] THEMND:

Love the kernel, really smooth ill test battery life (V2) today and report back.
[LG Optimus 4X HD] Demetris:
So .... OP V2.1 is Up.

Enjoy!
[LG Optimus 4X HD] KiD3991:
Nice. Looks tempting. Will flash it when I'm out of busy mode.

Btw, the problem of high battery consumption due to wakelocks in no way is related to kernel right?

I used your kernel and got one of the best in custom rom battery life. 12% per average night. (screen on life 2-3min per %)

While my powerbank is gone, I have to use v10h underclocked to maintain a good battery life(without any advantages in anything).

Since my case would be near 6-7 hours in college and most of the time my screen is on to watch movies or read softnotes.

Is there any way to boost screen display battery drain? Like lowering voltage on display(heard from another developer).
[LG Optimus 4X HD] noppoer2:
I don't know if this question is already asked, but is it possible to add livecolor? I hope it is possible :D
[LG Optimus 4X HD] dokii22:
I didnt mean to disrespect your work,I'm just asking to solve my problem.

Do you think that combination of stock ROM with your kernel could prolong battery life because cm doesnt have necessary battery saving tricks or maybe Zaiben ROM ? :)
[LG Optimus 4X HD] ilan_75:
Do you change something in the control of the GPU? found the perfomance in game less good than before. (Hyper/cfq)

Wasn't possible to change the frequency of the gpu, or it's just my dream?

Gpu is 520mhz, I can take it to 6xx but does it worth it? Your call.
[LG Optimus 4X HD] laufersteppenwolf:
i tested it up to 700MHz, and all above 600MHz gives me the same performance, it only needs more power ;)

so my suggestion is to make 484 or 520 as default, and overclockable up to 600 ;) but it's your call ;)

BTW, how's the phone going?

First off all, I really enjoy all the work you are doing for the 4x HD and especially this kernel. So thank you very much for your great work!

Whatever you decide to do, thanks again for your work!
[LG Optimus 4X HD] @non4:
Impossible. The on screen time is related to a physical component. Unless its possible to somehow undervolt a screen which I doubt there's nothing that can be done about it

+1 on the battery life. But undervolting the screen IS possible, but honestly I do not know how, a developer in SG Wonder did it, screen time improved and standby time awesome.

Edit:

I know its bold to ask, but is it possible to add the active CPU core ? Set it in on trickster, using less cores in this phone is possible because its awesome.

About the kernel we want it fast and good battery and, for me, in all these releases you achieved the target. :highfive:

If the phone becomes slow it will be a pity as much a battery devorating one.

Please do not change your philosophie, keep the same line, just naturally improving as you do.
[LG Optimus 4X HD] disadjusted:
battery + speed

this somehow has been achieved on some earlier nightly kernels for the defy but has been dumped in favor of other developments... increasing saturation and reducing brightness might have similar effects though...

that what trickster does would exactly my suggestion: making a scheduler out of it that reduces running cores to 2, underclocking and undervolt them (will still be fast enough for daily usage, browsing and stuff) and adding an option to either manually or automatically at severe load it adds the other 2 cores and perhaps also increases clocks.

might that be possible?

should save a lot amount of battery... shouldn't it?
[LG Optimus 4X HD] KiD3991:
In our case, brightness itself won't be a big matter, 20% and 40% have very close battery effect, not confirmed for gaming.

Saturation wise, I'm not sure of that.

that would require the restructure of the kernel architecture, its not easily achieved. Although if the devs wanted to, they can do it in time.
[LG Optimus 4X HD] Maczuga:
I've just checked the OTG function and it's not working. Nor with simple USB pendrive, nor with external HDD drive (even with additional energy supply). It would be nice to have it on our O4X, without waiting for kholk kernel to be stable for very daily use.

Good job anyway, and keep working!

PS: Also there is a bug that doesn't allow for CPU to go below 340MHz
[LG Optimus 4X HD] GizModio:
I have to agree, it is weird. But Apple started the saturated colours with the iPhone. Everyone else is following. I have to admit the saturated colours on the phone screen just instantly makes the phone that little bit more sexier! Especially it being a Super IPS True HD screen! Imagine that!

But I agree, the screen is fine how it is. The less tech savvy of us think because they have a screen that is more colourfull, they would then instantly believe that they have the better screen. This is completely forgetting about the high pixel density!

The option should be there, If I had any coding skills, I would attempt it!
[LG Optimus 4X HD] noobiei5:
