Between F2FS TWRP by laufersteppenwolf is uploaded http://droideveloper.com/laufersteppenwolf/lg-optimus-4x-hd/recoveries/twrp-recovery-4x-hd/ if someone wants to download and flash read instruction before flashing. (Good Luck Germany :-p)
[LG Optimus 4X HD] maus01:
Yes downloaded it half an hour ago, no problemo.

Tried it a bit now. Must say... really snappy. For battery cannot say at the moment:D

[MENTION=1149134]Demetris[/MENTION] is is possible that we get liquidsmooth or/and SlimKat CM based with your latest kernel ? It whould be great.
[LG Optimus 4X HD] DerMoonEclipse:
As reported by some users, who have asked the support, the p880 in Germany will become an update, regarding baseband i think.

E-Plus and O2 (German providers) have changed something our p880 is incompatible with and the update will fix everything (Base should be 4.1.2 as it already is)

So problems of RIL with these providers can! be gone in near future.

Hope best!
[LG Optimus 4X HD] Demetris:
Sure, as am little curious how this kernel will perform on linaro toolchain :)

LS coming up ;)
[LG Optimus 4X HD] dannychow:
Thanks for your comment~

But I 've tried flashing the newest V20B rom to the phone long time ago before flashing the current CM.

Is it still useful to flash the V20B again? (20B is still the newest one in my country)

What is the idea behind?
[LG Optimus 4X HD] Demetris:
Sure! if they tell us what they did.

[MENTION=2111458]dannychow[/MENTION]

To check if you have the same issue on oem rom, that’s the idea.

If you still do is a hardware issue.
[LG Optimus 4X HD] xperia u20i:
Hi, i'm curious. Are you gonna consider to update kernel to 3.4 or maybe 3.10 version i near future?

Maybe when new android version will come out. What is your opinion?
[LG Optimus 4X HD] Demetris:
Too much time and effort needed but the real question is what for?
[LG Optimus 4X HD] xperia u20i:
It will be good to be max up to date. But if is there big improvement or not i don't know, really. If you are 100% sure that we can't have any big profit from that update then....well, is not worth. Probably we cant get much more from our phone i think, battery is bad because hardware and it can't be do much on software basis.
[LG Optimus 4X HD] b886b:
Yeah, I think the major problem we are now facing is the battery and if updating the kernel didn't yield any improvement in battery or performance, it might not be worth to put into that much effort or time to do so.
[LG Optimus 4X HD] dimi89:
Nooot going to happend as it isnt worth fixing since users already started switching to other newer devices.

[MENTION=1149134]Demetris[/MENTION] :D Thanks man i know we-I are sometimess pain in the lower back but we just love your work and love LS and SK roms :)

As the link above tells us we are a few users with this kind of problem - and it seems like there is no solution.

I tried today with a new sim-card holder and as I suspected - NO LUCK!

Flashing KDZ is not possible - gets stuck at "3GQCT:WPARAM=2010, IPARAM=207"

I flash every new Nightly from Demetris and DAMN what a shame that when we finally get this great and smooth ROM generated by Demetris very hard work (he sure is worth some free Ouzos) for this "original CRAPdevice" my phone ends up as a bloody pad only working with WI-FI.
[LG Optimus 4X HD] Kanad:
LG used to have issues with 128K sim cards, can anybody confirm who had the baseband problems, if they have 128K simcard?

[LG Optimus 4X HD] Demetris:

I would say for >1 y old it is still holds easily for the whole day and more so for my kind of usage that is moderate to good i am very pleased with my work ;)

[LG Optimus 4X HD] charly394:
Switched from CM 10 to CM 11 nightly now

As a long time lurker on this thread I really appreciate Demetris work. I now switched from CM 10 to Nightly 2014-10-11 and I'm very impressed.

Cold GPS fix (device only without network) is very fast

Battery life is very good

Wakeup from deep sleep is instant (I'm a former Optimus Prime 2.7 user and there was this 2 seconds lag)

But the best 2 things are:

- no network problems switching airplane mode on/off

- 3G<->2G switches work without a problem (I'm on german D1 and had problems with CM 10)

Demetris: you really really gave my device a brand new life :) THNX
[LG Optimus 4X HD] Sk0rpi0n89:
I update to latest version from 11.10 to 12.10, and now I return and menu button do not work, unitl home button works normally?

On-screen nav bar working normally.

EDIT: I solved the problem, i disable default keyboard and install xperia z keyboard. But when I upgraded to latest version my keyboard is wiped, I install the keyboard again and everything works perfectly and is fast as lightning.

Nice work Demetris.
[LG Optimus 4X HD] EB20XY:
Little issue, but would be great if it will be fixed:

In nightly 12.10. I can not change volume in profile settings. Is will not be stored and used.
[LG Optimus 4X HD] dijon:
This rom with who kernel works great? Kernel is included? Currently i use kernel iodak.
[LG Optimus 4X HD] Sk0rpi0n89:
I use cm kernel, form me is best for daily use, iodak kernel is faster, but i must recharge my battery twice at day, and i use my phone only for calls and messages.

so i stay on stock cm kernel.
[LG Optimus 4X HD] Bubino75:
Already present in 10.10 (post #1975)

Where from download the cm kernel for p880? From here - https://github.com/CyanogenMod/lge-kernel-p880 ?
[LG Optimus 4X HD] xevic:

You should say "very nice". For me this build 20141012 performs very well
[LG Optimus 4X HD] tamer7:
Lesson learned: don't take your phone to warranty repair unless you can afford losing the ability to unlock the bootloader (effectively losing ability to flash any custom recovery and therefore any customer ROM).

Though they did fix the network drop issues.
[LG Optimus 4X HD] SnowRaptor:
Ouch :( sorry for your loss. Can you still root it at least?
[LG Optimus 4X HD] tamer7:
yes. root is still possible.. unlock bootloader however always ends up with "unlock permission denied".. several methods tried to no avail.

3845#*880# -> bootloader lock status -> always shows locked.

even tried LGMobile Support Tool -> Upgrade recovery (downloads full kdz and flashes recovery portion) then attempt to re-unlock, same error :(

EDIT: I was able to flash CWM recovery even though bootloader says its locked via the dialer menu (and despite the unlock permission denied errors prior).

This exactly the same experience reported in the following post:

Hi

I'am on 12.10

I have the old issues of speaker:

If I use speaker in a call the next one in the headset present a very low volume even if I set the volume the max value.

I have to reboot to obtain a correct value

(I have done a clean install for 10.10. For 12.10 I wipe cache, dalvik and format /system)

Someone else have this issues?

[LG Optimus 4X HD] fguzmant:
+1 on low speaker issue, I'm on 12/10 too. Despite of this, everything work just fine in this ROM, thanks a lot Demetris.
[LG Optimus 4X HD] Bubino75:
Set volume in profile doesn't work

Even if I do a clean install, I had issues with clock central (on status bar). Sometimes it not appears

Bug in 12-10 nightly with default theme?

Change wallpaper 3-5 times in a row, wallpaper crashes and you get black background, and afterwards if you turn off the screen, it won't come back on and phone must be hard-reset by holding down the power button.
[LG Optimus 4X HD] Demetris:
All working fine here, changed wallpaper >10 times.
[LG Optimus 4X HD] SnowRaptor:
I had a few radio drops with 12.10. I'll try to get logs when it happens again. No problems with typing PIN because my sim is PINless AFAIK
[LG Optimus 4X HD] tamer7:
Could it be caused by nova launcher?

Update:

Reverted back to Trebuchet launcher and there's no issue changing wallpapers through there.

However, if I select nova wallpaper switcher and pick a wallpaper, the wallpaper disappears and gets replaced with black background and if the screen turns off, it won't come back on, and a hard reset is required. So, I believe the issue is caused by nova's wallpaper switcher for sure.

Apologies for wasting your time [MENTION=1149134]Demetris[/MENTION] :)
[LG Optimus 4X HD] LeonardHofstadter:
I had a mean radio crash last night. Sucked out 40% of my battery within an hour before I noticed it... After screen on, RIL came back (had to enter my pin) and all was fine again :silly:

[LG Optimus 4X HD] xperia u20i:

[LG Optimus 4X HD] Sk0rpi0n89:
I use nova launcher and i dont have that problem, only problem is radio drops an and i must enter pin code, after that all working normaly again.
[LG Optimus 4X HD] tamer7:
Thanks for replying.. I had edited my post 1 minute prior to your reply :)

That is strange, because I am pretty sure after all these trials that it is the nova launcher's wallpaper switcher. But, this is definitely not the right place to report it, so I will go elsewhere for now :)

I also have experienced a network drop yesterday, same day that I switched from Stock ROM to CM 12/10 nightly. Strange, because I thought it was solved after taking the phone for warranty repair (where they reflashed original V20C KDZ) and have been working just fine for 2 weeks on stock ROM without a single network drop.
[LG Optimus 4X HD] rootarded:
[MENTION=1149134]Demetris[/MENTION]: please have a look at this LINK! It looks like disabling fast dormancy in order to improve battery life may cause the exact issues some of us experience when used within specific networks.

Of course it will be a drawback in terms of battery life but I think it's better if everyone is still able to at least use the phone ;)
[LG Optimus 4X HD] alberteske:
did you try it? because it says it is for stock ROM only

There is even an apk to do it :)

[LG Optimus 4X HD] rootarded:
I wasn't talking about using that APK but I just wanted to give a heads up. My idea was that [MENTION=1149134]Demetris[/MENTION] might have changed something within the baseband regarding fast dormancy. Maybe the problem is located within the baseband's machine code, who knows ...

Battery life endurance test with 12/10 nightly

Scenario:

- Stock kernel , stock performance options, mini modular gapps, and whatsapp installed (no facebook/messenger).

- running in 2G mode most of the time with data enabled all the time (for whatsapp at least)

- 3G used briefly when fast web browsing (H+) is needed.

- mp3 playing about 3 hours.

- google maps used a couple times to pinpoint location only (not for directions), once in high accuracy mode and once in battery saver mode.

One unfortunate event during the endurance test:

Phone manually rebooted only once around 45% battery, because after switching network mode 2G -> 3G for brief web browsing, the phone experienced an unexplained lag, evident even when playing an mp3. cpu was also suddenly locked on 1000mhz, battery getting hot, and losing up to 20% battery in 20-30 minutes. Add to that quite an unresponsive power button; unable to unlock the screen for 5-10seconds at a time.

After switching back to 2G and rebooting the phone, about 20% battery was left, and battery drain stabilized. This was in early evening yesterday. Now it's early morning (over 10 hours later), and I have 9% left after playing a bit with the phone and taking screenshots.

End Result:

Battery life: about 1 day , 15 hours.

Screen on time: about 2 hours.

Screenshots attached.

I will try to reproduce the issue later to get logs.

RIL crashes

Hello,

all in all the ROM works really nice now. But I still have some RIL crashes from time to time (i'm on 141012 Nightly). This happens manily when i'm playing videos over DLNA/Upnp with the Fritz!Media App. So maybe it's app-related and its not bothering me too much, but i got some logs from the crash last time and I thought perhaps its interesting for some experts here to have a look at them.

So heres the link:

https://www.dropbox.com/s/cwdjpf8g3aqnssr/2014-10-17-22-41-03.txt?dl=0

Its quite a big file, but the interesting thins happened during the last few minutes. As far as I understood the log, the crash happened around 22:39:16.443 and I re-entered my SIM PIN at 22:39:50.193

Perhaps you can find something interesting in there ;)
