Sorry but is not the case...

Both Linaro and 4.4.3 are compiled from scratch over the same repo; one using linaro toolchain and the other using prebuilt android toolchain 4.4.3.

I've seen in the past that issue: a /proc/last_kmsg with info about an old cyanogen kernel... but I can explain that... my kernel hasn't anything from CM7, the patch from 1.6.35-7 to 2.6.35-14 comes from another repos (not CM7 repo, nothing to do with arcee...).

Well after look all the info, I don't have any idea of the origin of the SoDs.... every log fails in different state and without any error; it simply decides to stop working...

Summing that fact to errors on v3b/n (with original kernel), error on other different P970 mod ROMs, and errors at stock ROMs from LG, this smells like a LG-crap-gingerbread-ROM-release...

I'll keep the fight but I don't know who to do it...

Regards!
[LG Optimus Black] kingzain900:
I agree that it's probably some LG issue. However, I don't have any SoD issue at all. By SoD I assume that the screen turns black and nothing works correct? I have never received such an issue. BUT what I have experienced is the screen just glitching (happened ONLY 4 times so far since I flashed the Zeus ROMS). I assume this is due to my phone falling three floors down to the ground floor from my balcony (it has survived with just a slight scratch on the body, nothing on screen, everything working great).

I'm on Zeus v3.1n. No problems so far to report. I don't use GPS much so haven't checked that. VPN also I don't use since I don't need it. I have bricked my phone 4 times playing with stuff. Caused bootloops from flashing incorrect things, flashed a crazy amount of themes to customize, and in the end I just return to v3.1n and everything is working awesome (by saying this things will probably start getting effed up :D ). Battery wise I can get 17 hours using normally. I got 28 hours when i didnt do anything with the phone only made a few calls (no 3G no wi-fi nothing).

So great job Huexxx and keep it up! :D
[LG Optimus Black] gabwerkz:
Strange, rmcc@tenkian is arcee himself :confused: Darn LG...

Anyway bro... Try reverting GPS to stock, revert Extended Power Menu also (stock .jar's, apk's) and take it from there if SOD still appears.. Or for a mass test, make a flashable zip of them. Just a suggestion though...

A little OT, can I "echo" some tweaks in init.omap.post_boot? for example "values" for a Governor. Since I cannot compile from source (yet). Thanks.
[LG Optimus Black] Trekvogel:
Got a SoD again but last_kmsg doesn't exist so I can't make a logcat. I can confirm now that it only happens with wifi enabled. I don't know if that helps at all but with only 3g everything is just fine.
[LG Optimus Black] Huexxx:
First attempt failed... I'll keep trying...

Regards!
[LG Optimus Black] Huexxx:
I'm a little bit tired on searching the problem...

Yesterday I have a lock out... it was with wifi on... maybe it's related to wifi... let's center on wifi... please, people with SoDs can try to DO NOT ACTIVATE WIFI and to see if mobile stucks...

OT: Of course, you can do anything on that scripts... in fact I do a lot of things on this script... extract my boot.img and look inside...
[LG Optimus Black] Huexxx:
Another thing... /proc/last_kmsg seems to be effective to debug a reboot but not a phone stuck.... and, of course, if you take out battery, probably there won't be any /proc/last_kmsg because there isn't a involved reboot...

Regards.
[LG Optimus Black] EkimPadd:
Lets summarize the problems:

- Setcpu, No-frills, etc. doesnt work on our OB. It will set the cpu on max 300 (Does anybody already know why?)

- V4.02 or higher are experiencing SOD. (Nobody knows why, Phone is draining the battery and is getting really hot)

I think we have to look what LG did with the GB update, because tweaking with froyo was no problem at all.

Keep in mind that LG fixed all exploits so they tweaked GB really hard.....
[LG Optimus Black] gabwerkz:
Yeah, it might be wifi too, I've had freezing with V3.X. I'm on wifi most, GPS... hardly.

OT: Thanks, I'm experimenting values by echoing the governors to get optimum battery life. :)

Regards!

I have 20 test zips of a tweaked Stock V20N via dsixda kitchen (cygwin). None so far froze. I touched every aspect with (working init.d, init.rc, init.omap.post_boot, xbin, lib, bin etc.).

If stock Kernel (LG) has SOD with Zeus, I came up a conclusion from .jars and .apk's. Maybe far but it's worth a shot.
[LG Optimus Black] mdfaisal:
I Dont know if it helps...

Im running on zeus 3.2.n

1st file

Using 3G, not running wifii, either gps but having SOD.

2nd file

using 3G, not running wifii either GPS, screen freeze while playing games (bike mania) & Charging my OB
[LG Optimus Black] eistmxcxc:
Didn't happen again til now. Installed everything from scratch (full wipe & even deleted my sd card before). Configured google account and wlan (no change of policy). Installed apps via market - no restore of data. Flashed Zeus widgets, alarm clock and LG keyboard. Didn't touch Zeus script nor did I change launcher etc. Also GPS works without any problems. Hope, after 18 hours I'm out of danger...
[LG Optimus Black] Huexxx:
Two things:

- How and when have you taken this logs?

- Can U confirm that you got both SoDs with WIFI OFF?

Regards.
[LG Optimus Black] adxgrave:
Free from SoD since using 4.4.3 kernel yesterday, I've create a post and ready to report a happy case. Pause a moment to do something else and screen timeout like it should. Press power button, screen doesn't wake up. Press again, no luck. It's in SoD. No last_kmsg.

But it's an improvement from default zeus kernel, no SoD while charging and left overnight. I'm going to stick with it for a bit longer before trying stock kernel.

Edit: btw, remove gps.conf only doesn't make gps fix faster for me. Need to remove it and change to alternative too.
[LG Optimus Black] gsal:
Just had 2 sods. The first one with wifi off and gps on using gps test.. the sodlog

http://db.tt/PCs3uTye

And then i had a missed call and when i picked up my phone after 10 minutes or so to see who was calling ... sod. Default kernel with smartass2 governor and default i/o wifi off. Sorry for posting all these logs but i can't figure something out.. this is the second one

http://db.tt/qtmxLdBi
[LG Optimus Black] mdfaisal:
Iam using alogcat(free)-logcat Jeffrey Blattman from market

1st file: 26 - feb - 2012 morning 8 am

2nd file: 27 - feb - 2012 morning 1 -2 am

Iam having serials of SOD's and screen freezes during that day. 5 times I had to take the battery from OB. but I only save it 2 from logcat.

funny, my gps start normally, and I am not having SOD / screen freeze while using google maps, GPS Test, like couple days ago...

I am saving the logcat after I re-start my phone after SOD/screen freezes.

I was visiting my family in a small town, so I turned off my wifii and start using my 3G conn
[LG Optimus Black] Huexxx:
Thanks but a logcat after the SoD means nothing... I know it's very difficult, butwe would need a logcat DURING SoD, to see the last things made by ROM/kernel...

Regards.
[LG Optimus Black] Maneth:
DELETED.
[LG Optimus Black] dflt:
I've got complete freeze playing Whale Trail on stock v20n. Nothing worked I had to take out battery. I've only applied some build.props tweaks from knzo's thread. So maybe that's the problem.

During the hang I've got

WiFi on

Data off

Bluetooth off

GPS off
[LG Optimus Black] N00BY0815:
Really only build.prop, or also some other tweaks, like libsqlite, or remove the file from egl, to get higher fps? This LG update keeps getting stranger and stranger... Seems like they made it in one night :p just to provide us with an update, in order to make us stop crying for one :D
[LG Optimus Black] ruibullseye:
is this Version the 4.02b in terms of battery life, better then NOVA 8 ?
[LG Optimus Black] ramrod:
Hi.

overnight i have a death phone.

it awake only with charging. pull battery doesnt help.

akku had 0%

Sent from my LG-P970 using Haushalt
[LG Optimus Black] grnfeuer:
hey huexxx, i got the sods when wifi is on, mostly. so maybe youRe right, the sods may come from wifi bug.
[LG Optimus Black] re4lsk:
don't know if is relates to SoD, logcat is very strange, something bout wifi supplicant repeated over and over(this doesn't happen on logs in CM), maybe it fills memory and that's what causes the freeze.

Trolling in the deep
[LG Optimus Black] trinity1:
Chaps, don't know what u did with your phones...

So far I DIDN'T HAD ANY SOD/FC or whatever.

What I did:

- formatted sd (FAT/ext4 - am going to delete ext partition since it is not supported)

- copied all my files to sd (including rom .zip)

- performed FULL WIPE: data/factory reset, cache wipe and dalvik cache wipe)

- flashed the rom

- gone through configuration

- played with the phone looking for bugs. none found so far (at least none zeus rom-related).

- gone for battery calibration (fully charged with phone off, disconneted the phone turned on the phone, connected again, swithed off and charged again, then on and battery calibration with the app included in the rom)

- stressed a bit the phone with several different configurations (as I remember I already said). yesterday I had wifi/gps working together and sygic active. The gps got sats in 1 minute and 35 secs (first time). Second time it fixed in 15 secs. (using stock gps config, nothing changed from zeus script).

- another "play": data connection/gps active. No issues

- again: wifi/gps/music and data/gps/music. no issues

- performed a lot of continous changes in contacts (add photos, so stressed the phone even with gallery), changed phone numbers etc. no issues (after 1 hour the phone started to slow down a bit, but that was due to the processor, it's not rom-related).

In all cases battery isn't more hot than all the other android phones I played with.

So:

case 1: maybe the rom config has some problems

case 2: maybe you have to try to go for a FULL FRESH installation.

Another option is that I'm luckier than those who got problems, but I'm enough skilled [I rooted 1 HTC Desire, 2 Samsung Galaxy S, 2 Samsung Galaxy ACE, 1 Samsung Galaxy Next] to believe that for most of you case 2 is that one you have to go for.
[LG Optimus Black] huulivoide:
With the 4.x series Im not getting that many BSoDs any more,

but istead of not waking up it just hangs screen on from time

to time. I assume the stock kernel is the binary blob from the

stock rom. Could a compile a pure LG kernel for us to test? I

mean like without all the patches. To see if it is some of them

that is making it hang.
[LG Optimus Black] dflt:
Check out OP.
[LG Optimus Black] dflt:
:rolleyes: maybe those two also but that was long time ago and its hard to remember.

[LG Optimus Black] Huexxx:
Please, pass me the exact mods you applied to your rom, please...
[LG Optimus Black] Huexxx:
Forget it...
[LG Optimus Black] ontour:
Re-flashed v4.02b (gcc 4.6.3) again last night, restored my backups and ICS theme, but I fixed permissions in recovery and then in Rom Manager, rebooted and put it to charge during the night. WiFi, Data, Bluetooth and GPS off. No SoD like the night before.
[LG Optimus Black] dflt:
Maybe silly script in bash could help us with SODs? Something like:

W='/sdcard/'

while true; do

echo $(date)\n$(dmesg) > $W/dmesg

#ps not working on android as excepted ;>

#ps aux --sort -rss > $W/psaux

sleep 15s

done

And everyone that has SODs should run it in the background.

Eventually we can install sshd and force it to run constatly on. And when SODs apears we can test if we can log in to phone (maybe it's gui that's locking up?).
[LG Optimus Black] theaks30:
can we have the marvel 3.0 theme on Zeus Rom Heuxxx?

please...am a noob :(

i cant even mod something
[LG Optimus Black] dflt:
Ask in marvel thread for flashable theme. Also go to subforum "Theme and apps" and there are some themes.

Also could we possibly divide this thread into two (sth like in P500 forums)? So all the unreleted questions to development would be asked in "General" subforum?
[LG Optimus Black] adxgrave:
+1 this. Dropbear is good enough. Tried to install sshdroid from market but it won't run with ads being block. There's dropbear binary from cm7.
[LG Optimus Black] explor3r3:
my first SoD today

- Zeus Rom v.3 N

- WIFI ON (WIFI TX at 11dBm)

- while browsing with the stock browser (2 tabs opened both on xda forum) and switching between tabs every 5 or 10 sec to see if the page was loaded.

here you have the sodlog if you can catch something and if it helps pulled from /data/dontpanic/last_kmsg 1st one it` from 27-02 and dosen`t have much and other it`s from today i think it`s before and after the SoD (2012-02-28 12:55:01 UTC i think this was the time when i put back the battery, i don`t know to read too much in sodlog yet) 2nt attach from today SoD it`s too big for a txt , thanks
[LG Optimus Black] eistmxcxc:
Did the same the day before yesterday. Today first SOD :mad: Couldn't create a log, because I was at work. The place where it happened was a hotel with a hotspot. Thought it could be the reason. But in the afternoon I had to go there again, no SOD then. Fixed permissions now, perhaps it helps. Let's see. I just have to say, I won't give up, because this ROM is great! :D
[LG Optimus Black] tapeone:
I got a SOD again today, when i switch wifi on(switch wifi on, verify email, "close" screen) and afeter 5 minute--->SOD.

I can't to do log. Huexxx, maybe u can try another "wifi setting/file" from other rom or smth?
[LG Optimus Black] re4lsk:
how to get a log after a SoD

this is for windows only, if you dont know how to do it on linux, search for it.

things you'll need to do a last_kmsg dump:

- Windows PC

- LG Device drivers installed

- android SDK instaled

- cmd knowledge

Steps to do a lastkmsg dump:

1.-when you get an freezed screen/SoD pull your battery and start in recovery (at LG

logo press power+voldown) you must be quick, because if roms loads last_kmsg will be erased.

2.-plug your device

3.-run "cmd" with admin privileges

navigate to the SDK directory (will be different depending on where did you installed the SDK) for me is

C:/cd program files (x86)/Android/andorid-sdk/platform-tools/

once there type

C:/program files (x86)/Android/andorid-sdk/platform-tools/adb shell

now you are in shell of the device to get the last_kmsg from the the device type:

#cat /proc/last_kmsg

copy the data and pastebin it... now you can normally reboot your Optimus Black

thats all.

if something is not right, please let me know.

additional info:

you can reboot your phone from adb typing

~/adb reboot recovery

but I don't know if that works when you have an SoD never tried it.
[LG Optimus Black] Maneth:
I can't use GPS (France) on Zeus 3.2, could you explain me how to fix it ?

I try to change SLP settings but nothing works. Could you help me please ?
[LG Optimus Black] trinity1:
that's the proof I'm not luckier than anybody (as I said in an earlier post): yesterday evening I had mu first SOD. This what happened:

- at 08.00 I turned on the phone and played a bit. NO data connection, NO wifi, just looked at some system apps (Gallery, Memo).

- at 09.00 I put the phone in standby, or at least I guess I did...

- at 18.30 I tried to awake the phone, but it was dead. POWER didn't respond.

- Pulled out the battery and rebooted the phone.

Couldn't grab a log, sorry. BTW, wifi was OFF (Im pretty sure).

---------- Post added at 08:08 AM ---------- Previous post was at 08:01 AM ----------

huexx, guess u have to update first post. as I understand latest release is V20B-based... Or just specify which ver is the latest release based on. Some people couldn't understand

Then, QUESTION: I see someone state that V20B is more stable than V20N. Could anybody explain to me what makes B more stable than N?... I have read a lot of 3.x zeus ver (

based on N

) talking about stable rom, and very few (or none at all) SODs with N ver of the rom.

Instead, we 4.x(B) ver are suffering with these damned SODs...

Maybe THIS is to be investigated...
[LG Optimus Black] reflexsa:
Well I had some issues with V3b and V3.2b where the phone didn't wake up.

I am now using V3N as per someones recommendation that it is the most stable and so far system up time is 164 Hours with no issue.

Battery life is also great.
[LG Optimus Black] eminent1410:
hope Huexx would fix SoDs soon :((. i love zeus rom so much
[LG Optimus Black] gabwerkz:
@Huexxx

You can try this to remove lag when answering phone calls (if there's any). If not, ignore.

MAX_PHONE()
{
pidphone=`pidof com.android.phone`;
if [ $pidphone ];
then
/system/xbin/echo "-17" > /proc/$pidphone/oom_adj;
renice -20 $pidphone;
if [ $MAX_APP -eq "1" ];
then
exit;
else
MAX_APP_STARTER;
MAX_APP=1;
exit;
fi;
else
sleep 3;
MAX_PHONE;
fi;
}
[LG Optimus Black] trinity1:
I got your assumption, but I'm curious to know whether there are data (no assumptions, I mean) indicating that N versions are more stable than B versions. That is: WHAT does make N better than B?

I'm asking that because if huexxx focuses on B version when N is actually better, maybe he can optimize his work... instead of spending time on a version which potentially includes issues.
[LG Optimus Black] EkimPadd:
Some Quotes:
[LG Optimus Black] trinity1:
- No time to simultaneously create both: Dev decision: it's fact but doesn't explain why B is more stable than N

- B is newer and it has a newer baseband: it doesn't necessarily mean that it's more stable, just newer (and I saw some of newer official ginger roms with more issues than the older)

- I'm using B in my phone since v3: again a dev decision. no certain data

- More people talking good words about B version: that could help, but as someone else already stated there are also some/a lot of people who talk good of Ns...

- And the last, and the most important, becuase I want it in that way... another dev decision which neither I nor anybody else can put in discussion.

Just to make it clear

: I'm not arguing or complaining, just giving suggestions about the opportunity to set (maybe) a new looking at the SOD issues.

A fact could be: how many N users got SODs? And how many B users?... If N is (potentially) better huexxx could investigate on differences between the 2 roms. As someone said: once u have excluded all the possible options, you found the solution (even if it looks impossible)
[LG Optimus Black] adxgrave:
The first time I'm able to capture last_kmsg after SoD (following re4lsk post) using adb shell in recovery mode. This SoD happened while I'm opening youtube app, led is responsive (turn to blue) when touch but screen freeze. Huexxx pls take a look there plenty of errors in there. Hope it will help.

Here we go: http://pastebin.com/td0ZmJyG
[LG Optimus Black] explor3r3:
i don`t think the kmsg can cache something , as in my sodlog yours it`s the same , starts after the phone reboot/restart or something the services , does not cache the time when the SoD it`s happening :(( cheers (but if this can help Huexxx it`s great)
[LG Optimus Black] Huexxx:
- This last_kmsg that you are obtaining are useless... look at the last line indicating that the phone are rebooting to recovery... this log is taken between the new startup and the access to recovery. That method is valid for phones with key-combo access to recovery.

- There are SoDs as well on N version. One SoD on N version is enough to assure that the problerem affect to both versions. The more people with B version, the more cases of SoDs...

- There are a new ROM created from scratch at my other post to try to resolve the issue. Please, people with SoD issues, blanks screen issues, etc., flash the new ROM and comment the results.

Regards.
[LG Optimus Black] adxgrave:
Well, I've tried. Let test the new one then.
[LG Optimus Black] dflt:
Lol I've got the same issue yesterday. Wtf!

BTW. I'm using stock v 20n+kernel eabi. Also tweaks I've posted earlier without debug.hw.sf. + echelon theme. WiFi and 2g. HTC keyboard. Egl file deleted. Fsync on. Deadline scheduler.
[LG Optimus Black] re4lsk:
what kind on response is that? we wery just trying to help.

thats why im back at CM7
[LG Optimus Black] ObiDanKenobi:
Hi, you took the words out of the context, don't be angry.

What he meant was: because the BLACK cannot go in recovery with a press of physical keys, you go on recovery via the "software" method. This method rewrites the last_kmsg (that contained the last events before the hang) with information from the boot process. And this information about the boot process is not relevant in investigating the SOD problem.

That's why he said the logs collected this way are useless.

I hope this clear out the issue.
[LG Optimus Black] Huexxx:
You can do what you want my friend. Thanks for your help but i was only explaining that it is useless and why.
[LG Optimus Black] johnnyslt:
i've just got a reboot today when running antutu benchmark during sd testing

here's the last_kmsg : http://db.tt/6oyXFkXt

i'm using the stock lg kernel, and i have to say that i didn't had any Sods in 3 days,

maybe there is some tweaks that's causing the Sods.
[LG Optimus Black] trinity1:
That's a fact I was talking about in my previous posts!

It's B-based, isn't it? Could you concisely tell us what changes have u done?

BTW, so far I had only ONE SOD. This is how I normally use the phone:

- at home at 2000, wifi on, check apps updates on market (if yes download and tb backups)

- turn off the phone and put on charge.

- turn of at 0800, go to work

- occasionally check whether there are SODs

- I'm on 2g network (because I'm testing signal strenght with the operator my father has - forgot to mention the phone isn't mine)

- sometimes activate gps and offline navsat (sygic) to test sats fixing time.

Other than that, gps, wifi, data connection is ALWAYS OFF.

kernel: that one the rom comes with (no changes)

governor: ondemand

I/O scheduler: noop [deadline] cfq vr sio

no gps tweaks

no wifi tweaks

no misc options other than default

display settings: auto/energy saver

apps on phone (except rom default apps): absolute system (never used so far), AK Notepad (used frequently), App Exctrator (never used so far), Astro (used frequently), Car locator and related bt plugin (never used so far), Dolphin HD (used sometimes), File expert (used sometimes), Infoblu traffic (never used so far), google maps (used a couple of times), phono (widget working), Quickoffice Pro (never used so far), Rom manager (used a couple of times to go in recovery), Smart tools (used a couple of times), Street view (never used so far), Sygic (used 3-4 times), Titanium backup (used frequently).

The SOD happened after a reallt short data connection session, and phone connected to pc via usb. after that I disconnected phone and put on standby. A three hours later when I went to wake up the phone, it was actually OFF, and POWER but didn't accept any input. After battery removing I managed to turn on.

Sorry for not taking a logcat but I couldn't go via ADB (as I understood that was only way to get an effective logcat, ins't it?).

That's why I'm saying that mabye is not a wifi-related problem: I didn't use wifi before the SOD (well, I used the DAY before, than I managed to turn off phone and turn on again without issues)

hope it helps :p

---------- Post added at 12:18 PM ---------- Previous post was at 12:09 PM ----------

not a good logcats reader, though: ... and if it is related with the way how the system put the phone in stanbdy after a wifi and or data connection? maybe it's thinking you're turning off... and then doesn't want to exit from standby?
[LG Optimus Black] neeewwww:
Just to inform...

Never happened to get a SoD - Using v4.01b (since the .02 patch doenst change THAT much to me). No "special" customizations, just a change at gps.conf to make it more "clean".

Using SmartAss and NOOP.
[LG Optimus Black] interdan:
The best feature of the Zeus rom: battery life! for the use that I do is really good.

Only 1 SoD, but are about 3 days That I do not have problems.
