I am using a charger made in China. Not the original one from LG. I am also charging my phone when it is off. I have no data loss and no network data lost.

Very strange because I had all of these bugs in all CM10.1 ROMs I used before. So I guess it is not kernel related.

No Problems here on TonyP Build4 and KK125 with the Battery and while charging, but i use for a long time a HTC TC P300 charger for different phones.

In my car a use a "aktiv" Brodit car holder and the Brodit charger also make no problems.
[LG Optimus 2x] sgspluss:
Tested it with more roms...

OpGaNex, Opti-Thrust & T-Build, no problems so far i use the charger from samsung galaxy y ;)
[LG Optimus 2x] x_justin:
We better stay on topic, the battery issue is not the most common I guess. Maybe we have to make a template for specific problems, in a seperate threat where people only are allowed to post their issues if they completely fill in the template, including logs and specific situations, but also people who can fill it in when it's working well. Many people here are doïng well by including logs and providing detailled info, but it's really not about gathering as much as complaints or well-working situations, we better stay focussed by analyzing the real problem and gather only usefull info.
[LG Optimus 2x] Patrick Morgan:
Ok,

I've moved my reply to the last post here, to private mail.

and relation to this freezing issue, i've opened a troubleshooting thread, so the Kernel thread can continue to work as a Development thread, and not get bogged down by any off topic issues, without solid proof that its either kernel or not.

Please direct any more freezing status bar issues to this thread

http://xdaforums.com/showthread.php?p=43258013#post43258013

And please do not bother, Pengus, or Tony about these issues, until we've found out for sure, that it is Kernel or Rom related.

Any input or help is more than welcome, but please keep the Dev section of XDA clean, for Development issues only.

Thank you.

Data loss issue update

This is a update regarding my previous post about data loss with 125.

I did a /system format, flashed tonyp's t-build 4, kk125, modded lg ICS camera and had no single permanent data drop anymore, while I had these drops almost immediately after flashing 125 on top of 124. Didn't change any settings (OC, manager etc). This could mean three things:

Somehow some systems files got corrupt after flashing 125 on top of 124 (simply re-flashing 125 again didn't fix it).

The permanent data drops start after an x amount of days.

Coincidence/luck.

This release now feels really stable (except for the battery issues, as described by other members, but I don't really care about that).. Thank you pengus!
[LG Optimus 2x] der.einstein:
Dear Pengus,

Thanks for this superb kernel!

However, I have strange problem, but don't know if it is kernel related: I watched a video using MX Player while suddenly the audio stopped. I tried everything from tuning the volume, adjusting sound settings in

Kowalski manager through wiping cache and dalvik cache. Audio even does not work in calls ! Only through speaker, music however only works with headphones attached... Could it be something with azdio routing?

I dont know which logs could be useful here....

Thanks!

I'm on tonyps CM10.1 T4 using KK 124, a switch to KK 125 did not do any good regarding this problem.
[LG Optimus 2x] jcdid:
Just did the same this evening... Waiting feedback too ...;)

EDIT : I had the data issue before, using PA12,PA13 and actually on CM10.1, from kk122 to kk125. I reverted back to kk121 but the problem appears this afternoon too for the first time with this level kernel... Like idea that is a rom issue... I'll post in the new thread now
[LG Optimus 2x] tonyp:
Thanks for the creation of the data loss thread [MENTION=894978]necrowakker[/MENTION]

I've asked twice in my thread that someone creates such a thread, unfortunately it never happened until now :)

I hope you guys will find a pattern or come up with new findings.

It would be especially interesting if 121 or 122 do really fully fix the issues - or any even older kernel.

And a general remark for guys reporting bugs. While giving as much information as possible is highly appreciated you should try to be precise as well and avoid redundancy.

Sorry, but I can't keep up with posts that barely fit on my 28 inch monitor. I'm usually checking xda on the go, and it's a lot of scrolling on 4 inch....

[LG Optimus 2x] pengus77:
Awesome news guys! So can we say that the data loss could have been caused by some weird system/rom stuff? Maybe something was borked in the pre-125 kernels zip/script/flasher? Let me know if a system wipe solves it for everyone so i can stop digging in the kernel code :D
[LG Optimus 2x] oneearleft:
Reset/delete all user data, /system wipe, and dalvik wipe, flash tony b4 + kke125, and titanium restore (user apps only), did not work for me: yestereday, sometimes no data connection (restart necessary) and freeze of all mobile connection (shows connection but no call possible)...

Now I am on pengus look ma + kke122 again (again full wipe everytime as described above).

[LG Optimus 2x] Patrick Morgan:
I know it may be a hassle, But try for a couple of days a full wipe WithOut a restore of your backup, using titanium, just for the giggles, and see if this may work, A full clean wipe for most of us has sorted out the issues.

also if you do restore one app at a time and use it for a few hours to see which one may cause a data issue, post in the Q/A thread on freezing status bar stuff too, so we can collaborate our experiences and find a solution, and try to keep the kernel thread clean for development.

3 - Data;

4 - Android Secure,

5 - System!
[LG Optimus 2x] orgler:
Though I think I wrote about this already some weeks back, let me recap what solved the data drop issues for me :

- switch to new bl with stock Rom (nvflash)

-flash v30b baseband deleting cal

- restore imei

- flash latest cracked new bl and twrp

- flash latest tonyp rom and kk kernel

Never had a data loss since then again, but of course I don't know if it was new bl, system full wipe, v30b bb or erase cal.

Mr Penguss,

Great work as always.. One thing i noticed and i want to bring that to your attension..

Whenever i watch a HD video with kk, the sound and video starts desyncing..

Except this, this is the best kernel.. No doubts..
[LG Optimus 2x] brugobo:
Negative on the format issue unless you have done modifications on the install script for 125.

I did full wipe when I switched from PA+kk123 to CM10.1 (gcc 4.8)+kk124 and still had complete 2G+3G network loss after about 100 hours uptime. I never do titanium backups, all my apps are reinstalled by hand from Google Play. In addition tot he wipe, I had just completely erased the internal "SD card" (to remove old asecs and data) and had some videos on the external one only. I used TWRP recovery not CWM. It was just rom zip flashing and kernel flashing, no rom modifications, no ics camera installs or anything like that. You canot get more clean and barebones than what I had. I do not use many apps and no games.

Having said that, I had a grand total of just one 2G/3G data loss event on 123 (calls worked) and a single complete 2G/3G network loss on 124, both after the 100 hours uptime mark (since I usually reboot often).

About 100 hours uptime on kk125 now (flashed with just dalvik wipe on top of cm10.1+kk124) and no problems at all. Fingers crossed.

This wall of text is humbly dedicated to Tonyp.
[LG Optimus 2x] jcdid:
No more issues for me too since Wipe Cache, Wipe Dalvik, format /system, reflash TonyP Build 4 then kk125...:good:

Still testing hardly vary on /off WI-FI, bluetooth when BT car connected, driving a lot today... DATAs are still ALIVE ....

Waiting a little bit to be sure :)
[LG Optimus 2x] calav3ra_de:
Since kk125 no more network drops, no camera probs, no reboots, nothing. :good:

Now, two things. My feeling is that sd readahead of 128kb is faster than any other setting. can someone confirm that?

The other thing is addressed to pengus directly, why do we have a clockstate of 1404 MHz - i assumed it to be 1400 MHz, because

all other steps up there are uniform?! My thought is that 1404 MHz is somewhat slow, and tending to crash a lot. Is this alright?

Thanks for all,

hail penguins! :o
[LG Optimus 2x] tonyp:
I've been on mobile data a lot today - and had 2 data losses as well. This is the first time I fully noticed it. This doesn't mean I didn't have one before, I just might not have noticed it some other times as I'm quite busy these days, and usually check my phone while being in wifi.

Happened out of the blue. I see the same strange events in the radio log - but no idea of it's cause.

I do come from a freshly wiped /system partition, so this isn't it.

I'll try to keep wifi disabled the following days to see if it will still happen. I always thought it doesn't hit me :cool:

I thought [MENTION=894978]necrowakker[/MENTION] had created a thread about the data losses, but I just figured out that has been about the status bar freezes, only :D
[LG Optimus 2x] pengus77:
Hey there, good to hear that all is fine for you :)

Anyway, the right read ahead value depends on the speed of your sd card. Let me explain a bit better: if your sd is slow as hell and you set a 1024 read ahead, it will take more time to fill the rh buffer than to actually access the files... and it will be slow, terribly slow. If you have a fast sd card, you can safely set a higher read ahead and you'll notice a nice speed bump.

About the 1404 Mhz frequency, it's there because apparently it's one of the Tegra frequencies. It was part of the original patch i picked and then 100% changed, but that freq stayed in. I can try to smooth it down to 1400 and see if it's better, but i never used it... i'm on 1.3 for daily use and on 1.5 if i need raw power :D
[LG Optimus 2x] xander59:
Just one question :

Is it a kernel issue when i switch 2G to 3G+data and I've not connection to the internet but the arrows are present?.. The issue is random.

Is it the same issue to the [DEV] Transition wifi/data ?
[LG Optimus 2x] Patrick Morgan:
More than welcome to add data loss to the pick dude,

when i've experienced data loss, i noticed that the signal bars are also stuck. so it may be related. so i've no problem with the Q/A thread being used for Data loss also, so it can clear up the development threads.

battery problems again on 125exp

my battery dropped again from 63% to 5% after restart was 43%

i must say that i tried 100p5 for 2 days and never happened this.

I put the frequency of 1500 and screen off 1000 and min 256 (if this info helps).

my phone was very hot then after i got the logs, my phone shutdown unexpected without restarting it self.
[LG Optimus 2x] calav3ra_de:
I dont have a slow sdcard i think. It's a sandisk, i thought that the random r/w values were ok. But

anyways, i dont use the sd at all, all apps installed on the internal one, that's why i asked why 128kb is faster.

To be more clear, i think 128kb results in shorter loading times of apps, despite having a few visible lags here and

there. :)

Have a nice weekend!
[LG Optimus 2x] BS86:
the name of the brand does not tell how fast it is ;)

is it a class 4, 6, 10?
[LG Optimus 2x] calav3ra_de:
the class of the card does not tell how fast it operates under certain conditions.

The class is just a hint at how fast sequential writing should be at minimum, not really saying how good it is

at small reads and writes (usually bad).

there are even cards that claim some class and dont accord to the standards.

it is a sandisk class 10 ultra ums 16gb though, from the worlds leading sdcard producer, no?

i assume it to have not so good random r/w values, though,

but as said. i dont store anything on it. the whole system is on the internal card so it doesnt matter.

keep in mind overall Android speed is determined by random access, not sequential(micro SD class!) write.

I'm sad about having to report bad news... All went good for a couple days, but this morning the data drop reappeared. Also the battery indicator was stuck on 0% while charging.

Try to do this :

- enable wifi

- put your phone on charge

- disable wifi

- enable airplane mode

- wait until 100% charge reached

- disable airplane mode

- enable wifi

In this way I have Wifi stuck in "enabling wifi" state and reboot is required.

Doing the following, wifi don't stuck and all works great:

- enable wifi

- put your phone on charge

- enable airplane mode

- wait until 100% charge reached

- disable airplane mode

Pengus cm10 ROM

New bl v30b
[LG Optimus 2x] oneearleft:
Bad news.

Did as suggested plus more:

1. full wipe + restore using ProgMaq's Full Brick Repair,

2. repartition and change to new bootloader using AIO tool,

3. using pengus cwm:

3a. reset/delete all user data, wipe of /cache, /system and dalvik,

3b. flash of look ma, and

3c. flash of KKe125.

(4. no Titianium restore!)

Suddenly got loss of connection, then tried to reboot, things got clothed up and phone freezed, pulled battery, and then ended up in endless bootloop. When finally coming out of endless bootloop, after each new boot I got warning about android system has crashed while typing pin for SIM.

KKe125 does not work for me. When I got home (after seeing Metallica at Roskilde festival) I plugged in the phone in stock charger, charged all night to finally be able to login and downgrade to KKe122. Now everything runs fine so far.

I was running CM10 look ma on new bl with bb v30b. I could not get logs (was at Roskilde) and current last_kmsg says sh: cat: /proc/last_kmsg: No such file or directory. Now, I am back to running CM10 look ma on new bl with bb v20s (and did not change ril).
[LG Optimus 2x] DrummerMuppet:
[MENTION=5071691]oneearleft[/MENTION] that doesn't sound right, mate. Bootloops are a sign that something's really messed up on your phone. By the sound of it, I'd say this is not kernel-related (and there's also the fact that no one had reported bootloops in a while).

Logs would have been nice, though.

Skype- deepsleep?

Since using kk125 I have problems in voice calls thru Skype, while the screen is on, no problems at all, but when I hold the phone close to my ear(like normal call) the screen goes off and the stuttering, call drops, the other side can't hear me, start..as soon as I take the phone away from my ear, screen goes on, all the described problems disappear immediately. I tried using incall profile in CPU adjuster, but even with min. freq. set to 812 MHz, there are problems. :confused: Logs attached.

Good news is, that for me the data conn. loss is a history, even with second core hotplug active! Had to do a full wipe of the ROM, since then, all is well! :good::good::good:

[LG Optimus 2x] oneearleft:
Tried this and it didn't help. I even flashed stock v20q!

You must be right: it must be hardware problem. My battery readings are jumping all over the place (on 5 different ROMS with 4 different kernels) and lifetime is <1hr. Have ordered a new stock battery.

So, please ignore earlier kernel bug reports from me.
[LG Optimus 2x] atg2x:
I finally think that i found the origin of the mobile data signal loss. I installed 3 different cyanogen based roms and checked 2 kernels. Same problem occured all the time. It seems there is an inconsistency between the v30b Baseband and the Ril bypass of cyanogen. Maybe a power saving feature.
[LG Optimus 2x] pengus77:
Interesting, can you please elaborate what roms and what kernels ? :)
[LG Optimus 2x] tavoc:
But this would not affect people on old Bootloader and a misbehaving signal, right?
[LG Optimus 2x] Kyrandialegend:
but with loss do you mean signal drop (then signal returns) or signal "blackout" (does not return al all) ?
[LG Optimus 2x] atg2x:
I tried your rom with kk125 kernel, avatar rom with kk125 and Temasek's V85 kk125 and Temasek's kernel. I believe it has something to do with battery saving policies because it usually happens when you do not use the mobile data over a short period of time (e.g. 20 seconds). As for the problem it goes like this: in the beginning you have HSPA then after a minute or so when you do not use mobile data because you read a page, 3G appears. When this happens you have to deactivate mobile data and put it to 2G. Then after 2 minutes you can re-enable 3G in the meantime you cannot even send a message.
