I noticed a 0.2a repack version. I have 0.2a. Shoul I install this???

I also like to know how to convert /system, /data and /cache to EXT4?? I know it's faster, but will I notice it???

Cheers!
[LG Optimus 2x] KillerbeeNL:
+1 :D installed it .... ?
[LG Optimus 2x] Lo_RaT_PeNaT:
it does not already online the version 0.3 yet I started the rom, I have seen a second file boot.img, that file would have to install through the root explorer? Many thanks

---------- Post added at 09:24 AM ---------- Previous post was at 09:04 AM ----------

I can not install anything nor repack of version 0.2a or version 0.3, in both cases I have stopped the phone in the bootanimation and I have to remove the battery and reinstall the first version 0.2a gives me no startup problems, any solution? Thank you.
[LG Optimus 2x] dr4go:
Finally some time to answer the posts... ;) Sorry for the long delay guys.

I previously stated, that this would be fixed with v0.2b. That is partly correct. The reason for that was the installer used in the old (=normal) version of v0.2a.

The v0.2a_repack is the same kernel with the same modules as v0.2a, but with a new - merged installer. NO new features, except that only the zImage gots flashed (i.e. domains/channels [12,13,14] are working if they previously were in the rom).
[LG Optimus 2x] dr4go:
Do you experience the same with v0.3? I changed the default max frequency to 1216000 MHz.
[LG Optimus 2x] dr4go:
-1... ;)

It was really a pain in the ass to get this damn v0.3 stable. Waiting for feedback. :)
[LG Optimus 2x] dr4go:
I have removed the older v0.2a, because v0.2a_repack is EXACTLY the same version as before (I didn't recompile it). It is just a new installer for the v0.2a, because some users experienced a few problems.

So no need to try it... Instead try v0.3. ;)
[LG Optimus 2x] dr4go:
Do not flash any of the boot.img files directly. They are just for convenience there if anybody needs already a prebuilt boot.img.

Always use the "2b-fps_x.x[_repack].zip" files if you want to flash a new kernel!!!

I also believe the boot.img installer of the normal (=older) v0.2a was more safe, because it would even work on a ****ed up /boot/ partition.

But because it would remove any existing tweaks made by the rom itself, I decided to partly revert the installer [note: that's quite the same installer as v0.1 or for example spica uses].
[LG Optimus 2x] Lo_RaT_PeNaT:
the matter is that neither the repack of version 0.2a, or with the latest kernel 0.3, I start with the rom, I was frozen in bootanimation, then I remove the battery and install a previous version, I will remove s_volt file in the folder d. init if this were the case.
[LG Optimus 2x] dr4go:
v0.3 released

Changelog:

- Improved battery usage

- Fixed a small Synaptic problem

- Patched to 2.6.32.53

- Changed default scheduler to BFQ

- Added some arm 2.6.35+ cpu features (=for snappier phone handling)

- Tweaked .config

- Faster startup time

- Improved EXT4 write performance

- Changed wifi driver

- Lots of sysctl tweaks

- Changed default max frequency to 1216MHz (previously 1408MHz)

- Changed frequency table (added a new frequency 1552MHz, removed 1100MHz)

- Tweaked voltages

- Integrated 64MB Hack

For the feedback I'm especially interested in the stability of the new tweaked voltages...

Just for reference... The previous table was:

216000 - 389000 - 503000 - 800000 - 1015000 - 1100000 - 1216000 - 1408000
770 - 775 - 825 - 875 - 975 - 1050 - 1125 - 1250

Now it looks like:

216000 - 389000 - 503000 - 816000 - 1015000 - 1216000 - 1408000 - 1552000
770 - 770 - 800 - 850 - 950 - 1125 - 1250 - 1350

Because Tegra2 uses hardware scaling, there shouldn't be any notable differences in the used frequencies. ;) Only the voltages should be the key point.
[LG Optimus 2x] dr4go:
That's very interesting. Which bootanimation are you referring to? The first bright white LG logo, the second LG logo with the progress bar or the third final bootanimation of the ROM?

Which ROM do you have currently installed? Which kernel?

i used setCPU to set the cpu :-) works super fast and snappy, really big difference from 0.2, lets see now if the phone still gives BSOD's with 1.4Ghz.

anything else to test? besides battery consumption?

phone restarted during benchmark with anTuTu; i removed the U.V and set the phone to 1.5, when it reached integer test the phone restarted again.

so now i will set to

1Ghz and without U.V

and see whats up-->passed the test

testing now

1.2Ghz no U.V

-->passed the test

testing now 1.2Ghz with U.V of -50 on all freq

-->passed the test

so it seems the problems happen on 1.4 & 1.5 dosent matter u.v....

any thoughts on this?
[LG Optimus 2x] zerocoolriddler:
Just flashed 0.3 and had 5 Freezes in 15 Minutes.

2 Freezes while browsing

1 Freeze after Alarm

2 Freezes after a Call

Maybe some Voltages for the lower Frequencies are too low.

Another Thing that catches my Attention is something that i read earlier.

It was mentioned that the Voltage-Steps between two Frequencies may not be bigger then 150mV.

The Step from 1GHz to 1,2GHz is 175mV, so this could be a Reason for some Freezes.

I didn´t edit Voltages to give a Feedback for default Kernel settings.

Otherwise, the Kernel is snappy and fast and can be No.1 :cool:

PS:

I´m on Hypnos2x 2.0 SP1
[LG Optimus 2x] shpapy:
use SET CPU to set it to 1.2 and it should fly
[LG Optimus 2x] zerocoolriddler:
That will only provide a higher drain for Battery and is not my Intension.

A Kernel should be stable with its default Settings...;)
[LG Optimus 2x] shpapy:
its a work around for now since the U.V is not working properly.

@zerocoolriddler : with -50Mv and 1.2Ghz all works fine passes all benchmark tests,
[LG Optimus 2x] dr4go:
True, but as you may know: Every phone is different. I have no hangups on my phone - that's also why I have used those frequencies / voltages set for the release v0.3.

So yes... as stated in one previous posts... I _need_ feedback to create a "default" voltage table that works on every phone.

EDIT: Also it would be nice if you could identify the frequencies by setting min AND max value of a frequency to one specific frequency.
[LG Optimus 2x] ryaneu:
if you want stable default settings , you should try deleting the s_volt_scheduler file in the init.d folder and reboot your phone after that.
[LG Optimus 2x] shpapy:
min / max tests shows stable untill the barrier of 1.4Ghz with default U.V an with -50 to all; besides 1.4-1.5
[LG Optimus 2x] dr4go:
Thanks for the feedback. As stated in my previous post: Could you try to set the min AND max frequency to 1.4 GHz and / or 1.5 GHz to identify the frequency that doesn't work?

Regarding the thoughts: As you've seen I did not change the voltage for 1.4GHz... so it may be as simple as it is: that the voltage value for 1.4GHz is set too low.

As those frequencies are not stock frequencies there are _of course_ no default values for them.

Should I provide you a version with higher voltages for 1.4 and / or 1.5? Also maybe... it's just that your phone doesn't have such a good tegra cpu on it. And you have already reached your limits...

Nevertheless I would never go beyond 1400mV as the stock maximum voltage is 1000mV and we probably are already exceeding the limits of the cpu. I don't want to screw up any of our phones.
[LG Optimus 2x] shpapy:
MIN/MAX @ 1.4 & 1.5 with u.v -50 --> phone buttons respond phone is not responsive, had to pull battery. ZeAm launcher crushed all seems quite bad.

MIN/MAX @ 1.4 & 1.5 with no U.V --> phone is working good (5582 score; only cpu)

scaling between 1.0-1.5 1552\ 1325Mv 1408/1225Mv 1216/1075Mv 1015\950Mv -->stuck on integer performance

SetCPU stress test dosent even start phone gets stuck

the Andrev OC daemon worked fine on my phone with his settings of U.V

also during all the above mentioned tests i lost only 5% battery (hey i know its not scientific but hey its a benchmark :-))
[LG Optimus 2x] carburano:
Great Dr4go! Thanks a lot... I will test it ASAP
[LG Optimus 2x] el_charlie:
Ok, making backup now. Will install it ASAP.

Will someone tell me how to convert my partitions to EXT4???

Ver 0.2a didn't do that.

Cheers!
[LG Optimus 2x] rexren:
I think I only get one CPU work after installing 0.3.

I can see both CPU work in 0.2a by systempanel lite.

Is normal or something wrong with me?
[LG Optimus 2x] dr4go:
I also use SystemPanel and can see both CPUs working on v0.3. Have you tried to "heavy scroll" on the monitor screen?

Anyone else has the same problem?

http://xdaforums.com/showthread.php?t=1137218 ;)
[LG Optimus 2x] dr4go:
Thanks to share your findings. But oh well... the problem is: Even with my new voltages... we already have one person (zerocoolriddler) with freezing issues.

If we decrease the mV by another 50mV on every frequency except 1.4 and 1.5GHz - how many additional users will then experience problems? That's always the problems with default voltages...
[LG Optimus 2x] rexren:
Yes and also open other apps in background.

After back to 0.2a,I can see both CPU working.

My rom is gueste 2.1 and use andrev to set oc & uv.

Hi:)

Really great kernel, but just wanted to share that my Optimus 2X cant handle 1500 mhz oc. My phone was preordered (1 gen). This is first kernel that handles uv. Thanks for spending time at us here :)
[LG Optimus 2x] rexren:
+1 Both cores work fine at 1.2G and really hope that can also work at 1G.
[LG Optimus 2x] dr4go:
Sorry, not much time 'til tonight / tomorrow. :/ But wow... that is horrible - why the heck does everybody get a different result? Have to think / test about that...

Could you please do me a favor? Could you run the same tests with the "S_volt_scheduler" file of the v0.2a (please don't forget to reboot after the file replacement)?

Somehow I don't believe anymore, that the cause are the voltages... And that you will run exactly into the same problems with the old voltages...

Thanks.

EDIT: @ all: Of course I will get this damn thing working with both cores. Some really really strange things are going on here.
[LG Optimus 2x] KillerbeeNL:
1 ghz is very important for me..after going back to 0.2a that has default 1.4 ghz i notice a strange smell after removing the back cover so OC is a "no go" for me.
[LG Optimus 2x] rjpa123:
Noob question:

Can I use this KERNEL on FR19?

Please and Thank you.
[LG Optimus 2x] el_charlie:
Well, I went back to 0.2a for a couple of reasons.

1. Can't reboot the phone with the app. Probably because the ram hack.

2. Using just an undervolt of -25mV and 1.2 max speed I had freezes. One of them was at the gallery.

0.2a at 1.1 runs very well.

I recommend putting the good stuff of 0.2 in the next version and no RAM hack or 32MB at most. There are many threads complaining about the disadvantages of using 64MB ram hack.

I know it's not apples to apples but CM7's iron kernel's creator explains what happens when you use different size hacks.

Cheers!
[LG Optimus 2x] KillerbeeNL:
the problem looks like it's voltage and OC.

why not go for default settings and change OC and voltages with an app?

this way everybody can OC and experiment with voltages so each phone can be adjusted and create an stable config .

cheers

[LG Optimus 2x] domain:
Same Problem with this Kernel BB0725 Ril 0725 rom V20o
[LG Optimus 2x] dr4go:
Thanks, noted.
[LG Optimus 2x] dr4go:
You don't fully understand. If you would use the "S_volt_scheduler" file from v0.2a and put that into v0.3 you would get exactly the same voltages as on v0.2a - except that the 1100MHz wouldn't be there, but the 1552MHz frequency.

--> but for the frequencies / voltages up to 1408MHz there would be no change. That is why I asked anybody to test this here. Sadly nobody reported regarding that.
[LG Optimus 2x] dr4go:
v0.3a1 test build

Guys... I have a present for you, which should fix the problem with the 2nd core not active and also should take care of the freezing issues.

Regarding voltage table: frequency 1552MHz is not in this test build.

Please report back.

Thanks.

bluetooth not stable on v0.3

Will try 0.3a1 later!:)

Bluetooth not stable on v0.3

I find that on v0.3 bluetooth will disconnected automatic in 5 mins but the phone still show it connected even I had tuned off my bluetooth headset LG HBM-235.

Edit:

0.3a1 enlarge the picture in Gallery is smooth than 0.3.

0.3a1 kernel version is back to 2.6.32.9 ? Does the 64MB hack inside?
[LG Optimus 2x] krajova:
Phone is much smoother now and there is no freezing when I delete/ install

Still as someone wrote in previous pages - boot in recovery mode doesnt work trough any of the apps I tried. It just shuts down the phone, so recovery mode has to be done manually. Could you look into that, since I come from 0.2a and it was working.
[LG Optimus 2x] Lo_RaT_PeNaT:
I still can not install their kernels in their latest versions, apparently there are devices that do not support the modification of the voltages, this step and imperticus kernels, and eventually had to return to the original, however thank you very much for their work.
[LG Optimus 2x] KillerbeeNL:
thanks for your new kernel, will it startup at default speed ? because my phone gets unstable and begins to smell like burn electronics @ 1.2 and1.4 ghz.

so I do not want to "hurt" my phone with anything higher than stock frequency
[LG Optimus 2x] shpapy:
@dr4go it seems that the memory leek is present , since after 50 hours of usage my free ram is @ 45Mb and the phone is super lagggggggggggggy.

i use swap as well
[LG Optimus 2x] KillerbeeNL:
okay ..testing 0.3 1a @ stockspeed and second core gets activated if first core is @ 50 % usage so second core is working !!!!

testing battery life now.......

P.S phone feels very snappy
[LG Optimus 2x] ryaneu:
Hi dr4go

I did not have any freezing issue in 0.3 but I still tested 0.3a1 ,

first thing i noticed is that the phone seems smoother & snappier in 0.3a1.

by the way is there any reason for reverting kernel to 2.6.32.9?
[LG Optimus 2x] shpapy:
O.k after really alot of tests I can say that UV (25-50) doesn't work properly on 1.2-1.4 only.

All the rest is good so far but I posted before as well that there is some sort of memory leak after long usage hours.

I will check the bt. Tomorrow as someome meantioned he had issues with it.

Also I included couple of images from the testing I can't really upload them all
[LG Optimus 2x] dr4go:
I have not changed anything in v0.3 regarding bluetooth. Maybe it was because of the freezing issues... Just wait for (the final) v0.3a... :)

Yes, the 64MB hack is inside v0.3a1.
[LG Optimus 2x] dr4go:
I haven't looked into this issue, yet. I'll make an alternative version of the (final) v0.3a for you. :)
[LG Optimus 2x] dr4go:
Yes, v0.3a1 was a test build to get rid of the freezing issues. It didn't attempt to fix the reboot problem... but since I know where that is coming from, it should be fixed with the final v0.3a.
[LG Optimus 2x] dr4go:
Remember one of my last messages (I love to quote myself :p):

And I sign my message once again. I'm even more mad at them... Apparently it seems that the code provided by nVidia and / or LG doesn't handle the stable kernel patches. That's the reason why the phone feels smoother & snappier in v0.3a1 and some users experience freezes with v0.3.
[LG Optimus 2x] RohanAJoshi:
1stly i was on DJ rom with spica rc11 with IcS theme.

It was too battery drainer.

So i flashed this normaly.

But phone stucked at lg logo.

Any reason ?
[LG Optimus 2x] KillerbeeNL:
ramhack is not good for 3D games so I read ??
[LG Optimus 2x] dr4go:
Which version did you flash? v0.2a, v0.3 or v0.3a1?
[LG Optimus 2x] el_charlie:
Exactly, also can affect video recording and reboot the phone via an app (to the system again or to recovery).

I already said this is not apples to apples but on this thread explains what happens with kernels and RAM hack (it's for CM7 but I think the idea applies here):

http://xdaforums.com/showthread.php?t=1359307

Cheers!
[LG Optimus 2x] dr4go:
Well... It reduces the RAM for the GPU, but gives it instead to the CPU - as simple as it is... But because we don't have that much RAM on our device I prefer to give more to the cpu instead.

The final v0.3a should be released within minutes... Changelog:

- Reverted the linux kernel patching series (apparently we are stuck on v2.6.32.9)

- Reduced RAM hack to 32MB

- Changed frequency table again (1015MHz replaced with 1040MHz)

- _safe installer added (@ Lo_RaT_PeNaT: that's the version for you to try)
[LG Optimus 2x] carburano:
Waiting for final release :)

Thanks Dr4go!!!!
[LG Optimus 2x] shpapy:
Sounds good but can you share with us why the frequency change? Can you also instruct on how to remove the memory hack or make flag version kernel install

Thanks alot for the hard work

Please have a look at the memory leek mentioned before

Thanks again
[LG Optimus 2x] dr4go:
Regarding the frequency change: It is needed for the 2nd core to work. Otherwise the 2nd one will get disabled via the hardware.

There is no way for you to remove the RAM hack.

Of course I will have a look at the memory leak. But as the v0.3 was a piece of crap I had to release a hotfix... there is no time for that in a hotfix... ;)
[LG Optimus 2x] shpapy:
Thanks for the reply the phone.crushes constantly with games due to the memroy hack probability

Nfs and gta also nfcommando its free from the market

Thanks

2nd core is working for sure tested with 1.2

Also it would be nice to UV 1.4 as well cz now it crushes and quite unstable with -50 / 25

Also notice the bug in the screen shot :)
[LG Optimus 2x] el_charlie:
Preparing my nandroid to go to 0.3a :D

I wish, however, to use the default speed after install and let the user to OC/UV at will.

32MB RAM hack sounds good to me because it's a gain for the CPU and not a huge loss for the GPU xD.

But I think that the reboot won't work either with any RAM hack.

Cheers!
[LG Optimus 2x] Lo_RaT_PeNaT:
thank you very much for the detail that has taken me, I'm really grateful, that said, if the voltages of the series, then something is wrong in my device because I still can not load the rom directly to me without the mobile phone is frozen get to load the rom, I have no idea that may be because your old kernel I can 0.2a install as normal, however with these new versions, so I'll see what I do, really wanted to prove his new job but I can not ask anything else, has done enough to try. Thank you very much indeed.
[LG Optimus 2x] el_charlie:
What does the Safe installer do???

Cheers!
[LG Optimus 2x] RohanAJoshi:
I installed 2b 0.3a
[LG Optimus 2x] dr4go:
No, I will not make the kernel to go with default speed. Why? Because I want to use my kernel as it is and not to have a second version for me of it on my sdcard.

If you prefer that or other undervolting values, simply edit the "S_volt_scheduler" file in the zip. If you remove this file from the zip, you will nearly have stock voltages and of course with stock speed.

--> the only issue with that would be, that the 2nd core would be not working. If you wish that, be sure to insert the frequency 1040MHz to the file.

Regarding RAM hack. Strangely the reboot app is working for me... it's a damn hell with the different Optimus 2X devices out there...
[LG Optimus 2x] dr4go:
Well... as I said... the only difference between the v0.2a and the v0.2a_repack was a different installer. v0.3a_safe uses the same installer.

The only thing you could try is to...

- firstly delete the S_volt_scheduler file from /system/etc/init.d ON YOUR DEVICE

- secondly delete the same file from the zip file of the kernel

- thirdly to flash the zip file and see if it boots.
[LG Optimus 2x] dr4go:
Refer to the faq. ;) The _safe installer flashes the whole /boot/ partition if it is ****ed up. The normal installer only flashes the zImage file.

When i connect phone to computer via usb cable, and select USB tethering it keeps asking me how i want to connect and i lose connection...

i.e I select USB tethering and it will give me internet connection, then after short period it will ask me again weather i want charge only/disk drive/tethering... etc.

It sounds like a cable issue but it does it with all 3 of my cables.......

Eventually after selecting tethering 5 or 6 times it remains on this setting...

Is it just my phone?

Could be an issue with tethering. Not sure as I don't have a tethering plan to be able to use it.
