Database Develop

Most common problem and its solution

Hey im using this phone for 1 month and im impressed by the performance. I downloaded few heavy games and apps like shadowgun and galaxy and few compilers and photo editing softwares. After installing them they were running smoothly. But after sometimes the app starts lagging. When i check the ram used i came to know that even i close the apps the app process is still taking some resources from ram i know its necessary for multitasking but the apps which you dont want to use further should be able to remove from memory. I tried with advanced task killler but after sometime that apps come back in the ram please tell a solution for and i think many users must have ezperiencing this. It is using up the memory unnecessarily.

use cm7.2 kang and use antoher kernel like vadonka, iron kernel.
vadonka provides 32mb ram hack and non 32 mb ram hack.
ironkernel provides 32mb, 64mb, and 96mb hack and non ram hack.
or you can install miui which is faster enough too.
or stock rom but already tweaked with another kernel such as horse power kernel which is nice and so on
just look the development section. LG rom is suck!!

If you have ram issues then you could also try to freezer these apps with titanium backup for example. Also, you could flash a custom kernel with ram hack of course...

Hello!
The behaviour you describe in you starting post is quit "normal" for the LG stock rom - it is a known bug - stock rom has memory leaks and you need to reboot the phone from time to time get all ram back.
The camera app from CM7 is ok in the latest KANGS.
CM7 has a better ram management and using a cutom kernel can speed up things even more (considerably).
But you could also install a custom rom based on a stock rom rebuild like i.e. Guestes or Manouches roms - they should work better than standard stock and are based on newer(leaked) sources...
ICS will come, but CM9 needs still some time and the ICS build from LG won't be here before next winter...

Err... im confused my friend. Cynomod is a custom rom rite? and what is a kernel ? can you change kernel in your stock rom? please tell.
Sent from my LG-P990 using XDA App

Yes cyanogen is a custom rom.
The kernel is a script that allows software to access the hardware. It's easy to change and there are many threads in dev forum about custom kernels. However I think you have to read some guides before

[Q] Need help about installing custom kernel on CM 7 - Vadonka's KANG

Hi guys,
Currently i just rooted my phone and successfully install CM7 KANG by Koboltz (sorry if i spell it wrong ) ..many thanks bro for the KANGin... It really smooth and trouble free from my experience using it for 2 weeks now
Now I really want to take my O2X to the next level by try to install custom kernel on it .. and my choice is Vadonka's kernel http://forum.xda-developers.com/show....php?t=1427646
However i always failed to install the recent Update 2012.01.17 .. any version i tried I always got bootloop on CM7 logo...always stuck there and wont go in to the system.
The only Vadonka's kernel i managed to install successfully is LGE-KaNG_120109 its super smooth and stable but i got a bug that i cant play my PES 2012 on it -- PES always stuck on konami logo and then force close.
anybody have the same problem with me ?
Is there any way i cant play PES 2012 on that kernel (LGE-KaNG_120109).. or is there any settings that i need to change ?
And are there any way to know what causing bootloop on Vadonka's newest kernel ? -- maybe is there something i need to do to diagnostic this maybe ?
(yes i did all the clean / wipe stuff before and after installing) but still it bootloop on CM7 logo on newest kernel.
other than that Vadonka has created or KANG one of the best kernel i think for o2x -- at least that is what my friend said
but still thanks to Vadonka
Thanks in advance for any help guys
UPDATE:
I tried Vadonka's latest Update 2012.01.18 but it still give me bootloop on CM7 logo.
I did try to use init remover by Vadonka to remove init script
I did try to disable compcache in CM7 setting
I did wipe cache and dalvik
Still i'm not able to boot

Try temasek's kang (link in signature) maybe this will work.

I see, I will try temasek's KANG... been actually thinking ti change rom but still learning about this rom and kernel stuff.
Thanks for the advice

Installing Vadanko tweaks failed for me aswell :-(. My battery drain is ridiculous (think I'll just have to settle with a spare battery)
I'm running Temasek kang and it is quite good.
Sent from my Optimus 2X using xda premium

Temasek rules!...
I use "CherryPics" Kernel (for CM7/Kang) with it
May be a driver/hardware module that causes your phone to hang and some other versions? (these parts are very "ROM specific" or Kernel inclusions...)

Yes I did try to use Temasek's kang #50 now, but still unable to use Vadonka's latest kernel.
Well on the good side, Temasek's kang #50 is bullet fast and rock stable for me. .. and after applying androidon tweak its just like bullet covered in butter.
I must say many thanks to Temasek, AndroidON and surely CM team and every other coder.
But I still kinda curious to try Vadonka's kernel....hope better luck next time

Hmm... There was a guy who had just the same problem as you, he couldn't boot any kernel versions after 9 January, so maybe you could try this version... Try searching for it at vadonkas thread.

Vadonka's kernel on 9 January is working fine, but still got several apps wont run on it .. one example is PES 2012, which always freeze and yhen fc.
I see that he is building new kernel (ETaNa).. wonder if this one might work ? I mean is it completely new? Cause I see its said that the installer will recognize something

I don't know if it is completely new, AFAIK, he only give it a new name...

Same issue here, after the jan09 version, i got a bootloop. Etena version same issue.

I would like to ask if I install custom kernel that is released by vadonka (the latest one is 30 Jan). Is there any problem if I flashed hybrid revolution v3.1 with the latest one??

I'm not sure about this but afaik vadonka made a lot of tweak along with his kernel and that might conflict with tweak in gueste rom .. please correct me if I'm wrong.
I think its better to wait kernel only installer from vadonka or you can try temasek kernel only.
I would like to try gueste 3.1 rom but maube I'll wait for it this weekend.
Sent from my Optimus 2X using XDA App

You can try out IronKrnl . The 32MB version has been stable for me for the last two days . And I have infact patched IronKrnl with Vadonka's init.d AIO tweaks and trying that out now . Vadonka's kernel was fast when I had it on my O2X but I experienced frequent FC's with the phone radio so I reverted back to stock CM7 kernel and patched IronKrnl . Having said that I think Vadonka's kernel is likely to be newer and more optimised if it gets stable
Always take a Nandroid backup of the existing stock & stable image before flashing a new kernel . It saves a lot of a headache . And to flash a totally different kernel I would recommend you to revert to stock and then flash the new kernel . The faster way would be to revert only the boot.img file but that might leave behind some stray settings .

also i have problem with the newest etana kernel by vadonka, it makes the cpu getting hot , and dont know why

Try to flash back prior to installing vadonka's kernel. Apparently there are some issues with his current kernel that I've experienced as well so it's better off with the stock kernel.

Currently I'm stick with Temasek kang #55 and with default kernel. Its been very stable and smooth for a week now, and u don't even have charging BSOD again since I set the screen awake while charging.
Latest Temasek kang #58 is out now, and I have yet to decide if I want to use it or use Gueste 3.1
Anyone tried gueste 3.1 from CM 7 without data wipe? ? ( only cache and dalvik wipe) cause I don't want to install all my programs from scratch. Is it even possible, since gueste 3.1 is also based on CM 7 ?
Sent from my Optimus 2X using XDA App

Hi,
I've been using Gueste 3.2 hybrid revolution for a day now, and i muat admit this is the smoothest rom i ever use in my entire o2x life.
The stock lg launcher is covered with butter. I even try to install go launcher ex, and ita still very smooth like never before.
Then i say many many thanks to Mr. Temasek for his Kang efforts and Mr. Stefan for this smooth rom.
My other experience today is for the pimp my cpu app always ask for super user privilege ... I always set to allow and tick on the remember box ... but it always keep asking.
For that i maybe a noob because i don't know how to sett the proper super user... but no impact on performance whatsoever until now.
Anybody know how to use pimp my cpu ? or atleast make it not keep asking for super user privilege. ?
I'm currently using Temasek Cm 7 kernel + voodoo sound dated 7 feb 2012 .. downloaded from Temasek mediafire.
Thanks in advance

I dont have any SOD on my 2X with...

I am having difficulties finding ROM twhich is not SODing every 2-3 hours. I have tried:
[CM7][KANG][FEB25] temasek's KANG BUILD P204-69 - FINAL RELEASE
[ROM][MOD] WIUI 2.2.24 Stable (GB) v4 (ICS) b0 - MULTiLanguage
update-cm-7-20120226-NIGHTLY-p990-signed
w/ and w/o Etanas kernels.
With those ROMs I have:
after-call SOD
charging SOD
also there is "SD card not found" bug with CM7 roms/kangs.
Modaco's GR6 looks more stable. SODs are rare but with Spica's kernels it starts to behave similar to CM7.
So if you have stable 2X with no or very rare (rare = max 1 in week) SODs - please tell me - which ROM with which kernel (if any) are you using? Any other mods/settings/apps?
Thank you!

Every phone is different... but if your phone is like mine... you can install any GINGER rom based on STOCK rom. Not Cyanogen.
For example, v20q (the last version available).
You must change the baseband too. For example the 725 from v20q.
If you want to change the kernel, the R11-R from spica is great, after that, all versions have problems in some phones.
Regards!

Have you checked that is not related to one of the programs you have installed? I used to have SODs until I removed a battery saver I had installed, that is half a year ago and I haven't had any since then.
Just to be sure in the safe side you might try to use your phone for a whole week w/o any apps and see if that is the case.
BTW, currently I am using CM7 nightly build 204.
Cheers.

I'm on Temasek's kangs with various Vadonka's kernels - for quite a long time. No problms found. I cannot recall problems on other roms either (I used mainly MoDaCo ones).
How about doing the clean install, i.e. do a full wipe, cache wipe, dalvik cache wipe, then install e.g. Temasek Kang #69. Just that - bare system. Then check if your phone is still unstable.
EDITED: the only app that you should install is GetRIL - to get your BB and RIL in sync. BTW, which BB are you on?

Some phones can't handle low frequecies (216MHz), you may change the lowest freq. with setCPU or an other tool like this. Maybe it helps.

BB is one more unsolved mistery - i cant understand - are all 725 the same or is there diference between them? i also tried that 1120 that was posted here on forums - that BB was buggy as hell for me so i went back to 725.

Thanks for the tips guys! First ill check Temasek Kang #69 without soft and will see what happens.

I use an older Temasek with IronKernel00. About 2 weeks old install? Never flashed another Baseband, i think i am on the stock(?) 725.
Not a single SOD. But again, never had a SOD on the stock ROM from LG, even in the Froyo times. Well, had a SOC when the phone were OC'ed to 1.55

Been using Temasek's kang for a while and it is quite stable. I'm on stock kernel as well.
Since you also mentioned that your device sometimes fails to detect your SDcard, I believe it could be corrupted. Have you tried formatting it? (make a backup first).
Sent from a galaxy far, far away...

I have been using the ICS Nova HD from the very start it went aviable for download and no SoD yet.

Hi. I had the same problems as you do when I was using Juice Defender with its profiles.
A month ago I deleted it and started using setcpu and I didn't had any SOD anymore.
Using tamasek's kang 69+ Vadonka's kernel

any more lucky cm7 users?

There aren't "lucky" users, sods are caused mainly by:
-radio errors: the phone shuts-off because baseband encounters a critical error, and kernel goes in panic. This is common in cm7 roms, because ril is closed-source (so radio commands are obtained via reverse-engeenering), so we don't know the exact commands and radio management. A normal phone usage should not encounter this kind of SoD. Juicedefender or Toggle2G tweak continuously radio settings (i.e. internet activation or 2G/3G switching), so in cm7 these app are not recommended.
-kernel panic: phone shuts-off because of a generic kernel panic. The main cause of kernel panic is a bad/aggresive-tweaked custom kernel, or UV/OC. An unknown cause of kernel panic happens sometimes during phone charging.
I DON'T RECOMMEND UNDERVOLTING, a lot of phone could not manage that. I had a lot of SoDs because of that.
If I wrote something wrong please correct me.

I haven't had any SOD yet. Use my 2X since last April.
Been on Stock, Modaco Fr19, Gueste v2.2, Gueste v3.1, Gueste v3.2 and am on Temaseks last KANG.
Tried different Kernels as well.
CM7 is highly recommended to be used with BB and RIL 218. Maybe this is the source of your problems.
If your Phone gets this SODs that often, I would revert to stock and return it.
Chances are high, that you will get a newer and bug free specimen.

if you use cm7 kang #69 and with etana kernel, i suggest you change the minimum value to 324 MHZ since it doesn't give me SOD at all. with my pimp my CPU configuration like this:
default: 324-1100MHZ.
idle / screen off: max & min 324 MHZ.
i don't Undervolt since it will give problem with my device. i guess i have the crap one can't undervolt

thanks for your advices. will check frequencies at start - then ill will start to mess with BBs and RILs.

I have found that this might be bb related issue soding my phone all the time. With 1120 and 1120 ril my phone is stable. No sods in week. I flashed back to 725 and i had 2 sods in one day. Also i had difficulties to find correct ril as with a lot of 725 rils i did had other problems. For know im using system in my sig and i am quiet happy.

[Q] recommended CM7 Kernel

Since i've been on CM7 with Temasek's kang i've been using Etana kernel. I've found myself wanting to play Plants vs Zombies and Draw Something among other games.
Are there any CM7 kernels that can play those games properly perhaps with ramhack and power saving tweaks enabled? Does Temasek's CM7 kernel kang play those games or does everyone stick with stock kernel?

I'm on cm7's stock kernel. And I can play PVZ fine.
I suggest you try stock.

Can't flash last Vadonka's
Hi everyone,
I believe Etana v3.0.y (OC version) is absolutely the best kernel for CM7 I've tried so far.
But today... I just couldn't flash the last version (15 APR)!!
The process stopped saying that my ROM was unsupported. I'm on Temasek's last kang (89) and I just don't believe that all of a sudden this rom is not supported anymore...
Can anyone give me an advice about this trouble ? What's happening?
Thanks in advance

I had that come up trying to change kernels. I think it has to do with the system not writable on the current 3.0 kernels. It wouldn't even let me format system in CWM but flashing temaseks kang would then let me format system. Also reflash temaseks kang after formatting system as well as gapps.

Ok, so do you think I have to reflash the kang and then try to reflash the kernel ?
I really don't want to format the system; if it's not possible, I think I will stay with the 12 apr. version as long as Vadonka will fix the trouble: by the way It's not that bad ...

Yeah you don't need to format system. I read you need to when changing kernels because some change it. Since your upgrading it won't affect you.

I would suggest, Temasek's unofficial CM7 build combine with Vadonka's kernel. There are some bug/issues regarding the kernel but you can try it out. I'm using temasek's stock cm7 with voodoo sound. It's in his thread. Check it out!

I think there is no "the best". It depends on your requirements.
Still not providing Hardware acceleration, i would mark a question sign at CM9. But anyway, if you dont do a lot of videos, you might be happy.
