It do automatically restart, even while phone not in use.

Never do hard reset when updating kernel.

Now I'm using v007, and worked fine.

cm 10.1 gives me network issues.

When phone goes to sleep for some periods of time (mostly overnight) so does mobile network,

meaning it has no reception (not the x though, just blank signal icon) and can't receive sms or calls.

Doesn't even get solved by turning airplane mode on-off, only solution so far is reboot..

(just to add some info, same rom which works fine with other kernel - already flashed a couple of times)
[LG Optimus 4X HD] dasloewi:
Same for me, but only on vanir ROM. On mokee everything works perfect. Maybe this info can help...

I did experience once on my stock JB, data signal lost during deep sleep at night and need to reboot to gain back the signal.

However, yesterday it's back to normal, no more recurrence.
[LG Optimus 4X HD] fguzmant:
I experience this issue yesterday with stock v20A and V8 kernel, I think it happens after I go through a bad signal spot.
[LG Optimus 4X HD] Ottonet:
Being noticing the same, lately.

Near my office there is a spot where the signal drops. Every phone's sgnal, no matter the operator drop to 0 in a range of 50 meters or so. All others phones i have, or had, recover as soon as one is out of that black hole. My p880 used to get the signal again when i had Iodak v7.

It is not so anymore, and if i do not stay away from that spot, once the signal is lost, is lost forever, or until I reboot.

I am on CM10.1.3RC2, to which I updated the same day I flashed V8, so it could possibly be a ROM fault.
[LG Optimus 4X HD] yrxe:
I am happy with this kernel. Great work!!!!!

Just i was doing some cleaning for memory and accidently removed my back ups. Could someone upload stock kernel (for v. 20c)

[LG Optimus 4X HD] iodak:
If someone is interested to test this

I would need to see if network is working OK.

I basically removed all that LG mess from baseband driver and make it stock nvidia and update it. I am using it for 4 days now and had no problems with network at all. Also baseband wakelock is enabled again so please monitor how is that. I always get it less than 10% of wake time and that is kind of normal. I used to get up to 70% awake time from baseband wakelock before. It is for CM 10.2 only for testing.

[LG Optimus 4X HD] arararagi:
Will test. When I tried to make the baseband driver stock nVidia before, the baseband just didn't work. Well done!

EDIT: Looks good but not sure if measurements are accurate. 0% for nearly 2 hours, then 5% in 10 minutes.

working fine for me. I cannot tell yet about battery consumption...
[LG Optimus 4X HD] tonhao12:
I am using test version for 16 hours now and it is pretty much the same in terms of battery consumption and performance...

I had signal drop for few minutes(in my work place signal is very unstable =(), after it came back I could make calls normally so i guess the issue is gone. But more intensive test should be performed to guarantee the issue is really gone....also no wakelocks here...

Best regards,
[LG Optimus 4X HD] moneyvirus:
i flashed it yesterday, the baseband powerlock seem to be ok lik 4-5% of the time instead of 70% in the past.

the Wlan_wacklock seem to be a hard one if i turn on the WLAN battery goes really fast and i get less deep sleep.

i'll test it for a couple of days a day with wifi on and with wifi off to get a good view of the WLAN drain.

until now it's a really great kernel with a lot of performance and with wifi of a awsome battery.

[LG Optimus 4X HD] OnAir783:
Is the xmm baseband wakelock really gone since v7 or is it only hidden in BBS?

But i feel very good battery standby by with v7 and v8.... but some problems with v8 and EDGE... it takes a longe time until i get a signal... with UMTS (H) no problem.
[LG Optimus 4X HD] @non4:
New test kernel is just as good battery with more stable connection. Haven't looked at wakelocks but haven't lost any silly amounts of charge either. [MENTION=3443693]iodak[/MENTION] please port to laufers version of vanir which has a different base (pure aosp)

Sent from my smart frying pan (Tegra 3)
[LG Optimus 4X HD] iodak:
Try the test version few pages back (085) it has different baseband driver see if it gets any better. In v07 and 08 baseband wakelock is disabled and that is all. It just won't keep device wake. Device was sometimes wake for like 70% of the time and battery drain was big. So [MENTION=5064727]arararagi[/MENTION] disabled those wakelocks so device can sleep even when baseband would normally call wakelock. That was good idea to lower battery drain and baseband driver worked just fine without calling those wakelocks. You cant say it is hidden when there really is no wakelock. Problem is that baseband gets somehow stuck in high power state and drains the battery but at least CPU and other systems are at sleep. I hope you understand me i am not so good with English.

So please try that test version and report back wakelocks are enabled in it.

Hi iodak, can this v8.5 test on stock JB rom?
[LG Optimus 4X HD] amkirk94:
I'm experiencing network issues as well. Is it because of the kernel or is it the ROM? If I roll back to v7 will I get the same issues?

I'm on CM10.1.3 RC2 and iodak v8
[LG Optimus 4X HD] iodak:
It could be rom, kernel, network provider or hardware fault. You need to be more specific, explain what is going on. Post a logcat and dmesg.

It is good thing that is not for new version.
[LG Optimus 4X HD] tool_king:
No, it's for CM10.2 for now. But you could repack it for stock.
[LG Optimus 4X HD] iodak:
It will be for all as soon as i fix some things like GPU scaling after OC it. It doesn't go to last freq when you OC it, you need to set last two freqs to desired value to to overcome that. Like this: 200 300 400 500 600 600.
[LG Optimus 4X HD] s4wk:
Good job iodak! I tried all kernels in the LG Optimus 4X threads. This is the most clean, stable and fast kernel i found. Even with INTERACTIVE governor the phone feels really really smooth. The battery drain is significantly decreased and there are not issues related to it.

What this device needs, it's a decent battery on Wifi, expecially when the phone is sleeping. Broadcom wifi board seems to have weird drivers issues which drains battery a lot, inside big networks with many PC's and devices sending for services' requests.

I know that LG used to fix this problem in some stock updates, decreasing the requests checking loop time, when the phone is in deep sleep.

So, i'm asking for this feature, if it's possible to have it :)

[MENTION=3443693]iodak[/MENTION] after much testing the worst I have gotten on v8.5 is 32mins of baseband wakelock in 4hrs 35mins. This us acceptable noise and hasn't rendered my battery unuasable. Data connection doesn't freeze anymore, and no more signal "death" where nobody can ring you. Overall its a good compromise, but I do feel slightly higher standby drain with data switched off and phone asleep. Good effort!

[LG Optimus 4X HD] @non4:
Because he removed all LG rubbish and replaced with stock nvidia drivers, maybe he can add the fix but it may need some adjusting to work with these changes

No, its our rubbish charging port or your cable. Does the cable wobble in the port? If so use your teeth or some pliers to gently narrow the gap between the two metal edges, this should also push the pins out for a more secure connection. Also make sure the cable is fully inserted, my port is terrible because I snapped the bezel that guides the cable

Hello for my 4X baseband Euro 20B after flashing 8.5 on arararagi vanir wakelock started immediately after boot 1h awake- 1h of wakelock, no deep sleep. So i don't know how did You manage to have only 6 minutes.

I have the same problem within the same time frame as yours. After 6 days playing with i had this huge wakelock (baseband_xmms_power) during all night , which drained nearly 40% of my battery, after pull the phone from charger. One thing that i have changed just before it happens was the cpu governor, before it was set to interactive and now it is set to ondemand, not sure if it could have any affect over this issue.

Sorry no this is not true. I have several chargers and cables and all of them will only let my phone charge to 93% for some reason with stock rom and iodak kernel v8.

So I want to try this kernel, but I have some questions.

3. How do I change back to CM kernel if I'm not satisfied with this?

[LG Optimus 4X HD] sPEADy:
I have one silly question is it a must to do all the following changes before I flash this Kernel or it works fine without all these changes from the OP ?

How to:

Change cpuquiet governor:

/sys/devices/system/cpu/cpuquiet/current_governor

How to dissable/enable fsync:

/sys/class/misc/fsynccontrol/fsync_enabled

enable = 1, disable = 0

Voltage control:

/sys/devices/system/cpu/cpu0/cpufreq/UV_mV_table

Current GPU speed

/sys/devices/system/cpu/cpu0/cpufreq/gpu_cur_freq

Get it from adb while runing game:

adb shell

cat /sys/devices/system/cpu/cpu0/cpufreq/gpu_cur_freq

Tegra cpu variant

/sys/devices/system/cpu/cpu0/cpufreq/tegra_cpu_variant

Max & Min CPUs online

/sys/kernel/debug/tegra_hotplug/max_cpus

/sys/kernel/debug/tegra_hotplug/min_cpus /// messing with min_cpus somethimes breaks going into LP core

From version 04 I reverted power saving in camera, early suspend and touch drivers.

This drivers will reset selected cores running. For example when you turn on camera for FHD recording min cores are set to 2 and max cores are set to 2, an min freq is set to 640 an max freq is set to 640, after recording is done all is reverted to stock and cores will plug in and out auto.

Because of that I added interface where you can dissable influance of drivers to freqs and cores online then you can set own setting and it will stick.

so to dissable drivers to do core plugging:

/sys/kernel/fc_ctrl/usr_core

0 enabled

1 dissabled

to dissable min and max freq change by drivers

/sys/kernel/fc_ctrl/usr_freq

0 enabled

1 dissabled

Min clock will still be reseted by that touch input boost

fast charge option

/sys/kernel/fast_charge/force_fast_charge

1 enabled

0 dissabled

It will trick device thinking you pluged charger. Remeber to turn it on before you plug in.

Clocks

Clocks are:

variant c1 c2 c3 c4

0 1600 1500 1500 1500

1 1600 1600 1600 1600

2 1700 1600 1600 1600

3 1700 1600 1600 1600

So I have this annoying problem with this kernel,battery life is fine and everything else,just this.

So basically I put on charger LG before going to bed at 10-15 % and go to computer to unplug and put it in airplane mod before going to sleep.

But I noticed I receive sound notifications battery is full so for example ten minutes after I unplug and leave it and then I see 96 % of battery,sometimes 94 %,never 100 %.

I leave it then 10 minutes more but it stays at 96 % or 94 %.

I dont what is causing this,I cant reach 100 % charge of battery, I keep it on charge and battery never reaches 100 %.

What is causing this ?

I tried doing nothing and he stays for one hour at 95 %,just as much I left him,sometimes he drain below 91 %.

This is quite a bug or issue,how to solve this ?

Have you checked if phone is getting many network packets? You can check with NetworkLog app. I have the same issue when PCs send broadcast packets, asking for services (Samba, Netbios, etc). The device responds to these packets and prevents to go in deep sleep. Then battery drain pretty fast.
