first flash kernel full wipe then flash rom and wifi modules

help?
[Xperia Arc Android Development] wedgess:
What device if its ARC everyone else seems to be fine.

Yes an init.d is created so when u disable it, it deletes that init.d script. When u change size it modifies your current value if the script already exists or create a new one with your custom size if the script is not already present.

google play crashed on two different roms, atomic 7 and x-stronger...

Works super on ARC S with Gin2JellyBean v2.4.0, just decreed some Volts and see how it will behave - will test for dew days. :good:
[Xperia Arc Android Development] Haidary.T:
On Xperia Pro, Google play store keeps crashing right before a download or update. I can confirm this because it happened in several different roms

with this kernel and when I changed kernels, everything went back to normal. Basically, Google plays stores FCs on startup. When I do clear

cache and data, it seems that everything works fine but when a download or update starts, it FCs immediatly. Sorry if it's not clear :\ Hope you

make the best out of this kernel! Awesome job!
[Xperia Arc Android Development] wedgess:
Perfectly clear:D I'll look into it in a while and see what I can do.
[Xperia Arc Android Development] RAGman7:
Hi

Installed yesterday, flashed Wi-Fi modules – all seems great on my ARC S. Everything works as expected enabled OTG – mounts my USB NTFS flash drive without any problems.

I experience some slight USB-MTP connections glitches – takes around 10sec before PC would see it (will investigate it more) USB-MSC works fine, right away connects.

As I’m new to kernels (was flashing custom ROMS for a while but just recently unlocked BL) will have to ask more experienced users for tips concerning battery, I just found out this morning after reading some RSS articles on my phone, some web browsing etc. the battery goes down very quickly much more then on ICS, I’m now on Gin2JellyBean 2.4.0,

I under-volt the phone 50mV, but it seems like it doesn't change much. My CPU set up is set on min. 134 max 1402Mhz, ondemandx and bfg I/O, - phone works super-fast and smooth I’m very pleased with that, plenty of free RAM, but the battery scares me as I can see it going down fast…

I have only handful services running such as basic google sync, k9 mail, Data transfer off, GPS off...

Any tips usage with this kernel would be appreciate it.
[Xperia Arc Android Development] pckloss:
I have the same on my Arc S with Gin2JellyBean 2.4.0. CPU set up is set on min. 134 max 1402Mhz, ondemand and noop I/O and the battery goes down very quickly with this kernel much quicker than on other.

Kernel works much better with G2JB 2.2.2.

[02.06] Updated baseband to 83 and situation has changed. Now battery runs normally on Gin2JellyBean 2.4.0. Great!

Hey since this kernel has some bugs so far, should I use LuPuSv14 or StockGB with root and cwm? Which one will give me best performance? I know you should not compare kernels but I think it's fine with with stock kernels. So what do you think? Tell me if it's inappropriate to ask so.

Thanks!
[Xperia Arc Android Development] Snoe II:
me too.

the notification light does not blink.

just constant light up when receive notifications.

fix it please.

btw, nice kernel for stock gb.

[Xperia Arc Android Development] wedgess:
It will be fixed in the next release.
[Xperia Arc Android Development] 17th_angel:
Nice!!

Im waiting for the next release :D

Its great that you havent forgotten GB!

Multi-touch?

I don't know whether it is my phone problem or the kernel problem.

But it looks like the screen can't detect multi-touch, only one finger at a time.

But pinch to zoom are work though. :confused:

[Xperia Arc Android Development] Anne_Droid:
wedgess thank you!!!! :victory::victory::victory::victory:

Finally a GB kernel for the PRO (yes, I still have the device, after not logging in for almost 4 months lol)

Thank you wedgess, you are awesome!!! :cool:
[Xperia Arc Android Development] 17th_angel:
Thank you so much!

Testing... so far, so good. The UKSM had save me 4MB of RAM, not so much but it is really welcome :D

But, two things:

Does the frandom have any effect on performance? (apps, games) Or it is just for devs?

It is normal that i just have around 300 MB of total RAM?
[Xperia Arc Android Development] zgmfx20:
Thank you so much for this kernel bro. :good:

Very fast for gaming. :D
[Xperia Arc Android Development] 1stichiban:
Works with latest gin2jellybean :cool:

Awesome work as always. Will report back, if necessary.

Thanks again
[Xperia Arc Android Development] zgmfx20:
I was able to remove logging via lupus menu for a while. But after removing script from init.d, then restarting, I can't get to logcat anymore.

There is no /dev/log/main file. Please see SS.

How do I reenable logcat?

Edit: Nevermind, I flashed another kernel and logcat then is working. I flashed this again and I guess logging in this kernel was disabled by default.
[Xperia Arc Android Development] DominikHolecek:
This kernel is the best what I have ever seen and tried - it has got much better and bigger performance than doomkernel, the only thing is that if I compare the free ram with dookernel, lupus kernel has a bit less free ram...

But can you say me what governors/IO are recommended for gaming, cos there are to much ...

(Thanks for your answers, now I have got my Arc S back and I can try it by my self...)

Hopefully they explained enough...
[Xperia Arc Android Development] DominikHolecek:
Thanks for your attention and answer, but I'm not a beginner and newbie. :) Of course that I've already known this governors in the list what you attached, I wanted to know if the extra governors, like smartassH3, darkside, superbad are better with this kernel than others...

Normally, I will try it, but I haven't got my xperia arc s at this moment, so I'm curious and I hoped that somebody has already tryed it and has got some experiences about that...
[Xperia Arc Android Development] duke_dreadmoore:
excellent

the Lupus GB v2 is excellent. It has more free RAM compared to doomkernel..

I've tried lupus in 1 week. It's really fast. I'm using smartAssH3 as governor, and sio scheduler.

No hangs, freeze, random reboots. I experience random reboot sometimes with doomkernel.
[Xperia Arc Android Development] DominikHolecek:
And do you think that this settings of governors, ... is the best or did find some better ?
[Xperia Arc Android Development] duke_dreadmoore:
absolutely best. Usually I used smartassv2 or ondemand. SmartassH3 is faster, and no noticable battery drain. Set it in lupus menu, and use init.d..
[Xperia Arc Android Development] DominikHolecek:
Thank you for your opinion... :good:
[Xperia Arc Android Development] 17th_angel:
^^

I had read somewhere in this forum that smartass v2 was the best in overall performance. It was in a review where they compare a large variety (at the moment) of gobernors and i/o schedulers in some test like: most battery friendly, scores in antutu (or vellamo, i dont remember). I also remember that the guy from the review recomended noop.

Yeah, ive found it:

http://xdaforums.com/showthread.php?t=1478418

http://xdaforums.com/showthread.php?t=1507204

Personally, i use ondemand and sio on games (and everything actually). In doomkernell i had lag using smarthassv2, but not so much with ondemand... so i use it for safe since then

I guess that it also depends on what games you're playing but i dunno.

_______________________________

By the way, i kinda sense that the wifi signal drops very offten, more than with doomkernel, specially when the screen goes off

Is there any baseband recomendation for this kernel? Or is the one recomended for the rom? Im on 64 (xperia arc s)

Thanks

Hi, on MK16i with AVID rom and gin2jelly 2.4 kernel boots fine but i experienced reboots with wifi on, background data enabled and auto sync enabled when trying to open an app the phone reboots (rom bootanimation appears)

got a logcat hope it helps.

i could still run android without auto sync ;)

Thanks again for your support to our device. :good:

Edit: Trying it out on stock .62 wifi, background data and sync => working good so far with no reboots :)

Sorry for the confusion. Maybe issues with custom stock-based roms :(
[Xperia Arc Android Development] wedgess:
Yes im aware I havent downloaded anything with Aroma yet so havent fixed it. Its now on my to-do list.

Good, u got me worried I haven't had/heard of one reboot with this kernel

If u get one more than likely it is yo or ROM. Which was your case :)
[Xperia Arc Android Development] 1stichiban:
Hmmm, maybe its me LOL.

been trying to set up mounts2sd reversed mount option with data and dalvik remaining on internal maybe need to check out other app settings. :)

Thanks again! :good:
[Xperia Arc Android Development] DominikHolecek:
I've just tried this kernel and the performance and I have to say it and rewrite my previous post, cos I wasn't right, this kernel is much better than domkernel. The only worse thing is that lupus kernel has got about 5 mb of ram less than doomkernel, but it's absolutely negligible, because lupus kernel has got a huge performance in games, is more user-friendly etc.... :D

---------- Post added at 02:14 PM ---------- Previous post was at 02:07 PM ----------

It depends on kernel too, but basicaly on rom - but in this case are these things the same. I recommed to you baseband 83 :laugh:
[Xperia Arc Android Development] Snoe II:
Undervolting?

Can I know the lower voltage that can I set for this kernel?

EDIT: Now I know that the lower voltage that I can set is 800mV.

The question is, can you make it even lower? 700mV perhaps?

Thanks in advance!
[Xperia Arc Android Development] Rambo_FT:
Updated and solved Google Play's "Force Close" problem.

But, I have another bad problem. The touch screen precision decreased. Normally touch screen precision updated in 2px to another 2px. But with this kernel, this touch screen updates goes to 4px.

I tested it with TouchMove app.

I show you screenshots:

Before Lupus kernel:

After Lupus kernel flashing:

This is too bad for the precision required apps. Example: FPS games (Modern Combat), Angry Birds, Smash it!, 8 ball pool bla bla bla...

My phone is Xperia Pro, can you restore this thing?
[Xperia Arc Android Development] Snoe II:
WiFi not working?

Any idea why my wifi is not working?

I'm not mean it completely broken.

But it can't connect to certain wifi.

:eek:

I can connect it normally with my home wifi without any problems.

But when I tried to connect with my office wifi, it just keep scanning.

I can connect normally to my office wifi with my blackberry though.

So I guess is not the router problems.

Any solutions?

Thanks in advance!

:)
[Xperia Arc Android Development] zgmfx20:
Did you already flash wifi modules in OP?
[Xperia Arc Android Development] Snoe II:
yeah.

wifi working like usual.

without any drop or problems.

the only problem is it can't connect to certain wifi.

public wifi mostly.

:/
[Xperia Arc Android Development] 17th_angel:
Yeah, in my work neither.

But if i flash a ics rom i can connect to it, so i think is a compatibility problem/lack of certain protocols (ac come to my mind) in GB
[Xperia Arc Android Development] Snoe II:
yeah I hope so.

hope it will be fix soon.

:)

I don't think it's the rom issues since it's a stock rom.
[Xperia Arc Android Development] 17th_angel:
Well, reading your problem again, it seems a bit different to mine. I actually can connect to some wifi, but not receiving anything (doomkernel). I cannot test with this kernel if is still there, cause i dont have the pass anymore.

But i have an issue with the music player.

When im playing a song and turn on/off the screen, i got a little cut in the music and its kinda annoying. I had it whit the doomkernel, but somewhat different: the cuts appears when i changed the volume up or down. Ive been trying changing the governor, the i/o and the minimun clock, cleaning cache, but its still there.

Do not know if is kernel dependant or is caused by the rom (x-gamer v2.0). Im on a xperia arc s baseband 83

___

Edit

By the way i forgot to mention that also im getting a moderate drain when playing music (also, dont know if its the rom) but when i buy it i got around 35-37 hrs of music, now i get around 20-25 if lucky.
[Xperia Arc Android Development] Snoe II:
Now I'm confuse. My phone can connect to my office wifi without problems.

Am I going crazy or the router got problem? :confused:

Hope this will last longer.

:)
[Xperia Arc Android Development] ChungHung.Chen:
You may check if your wifi router using 13 channels but your phone using only 11.

It may be the reason why your phone can't see your wifi in office.
[Xperia Arc Android Development] Snoe II:
It can see but can't connect.

Sometimes can, sometimes not. but mostly can't connect.

I'm not sure about that.

Btw, I'm already tried to setting my phone to 13 channels.

But its shows this error instead.

Don't know why. :confused:

[Xperia Arc Android Development] Vishalkris:
can u make multiboot work on this kernel...multiboot for GB and ICS
[Xperia Arc Android Development] gu5t3r:
Nope, that is the reason wedgess made this kernel because it's impossible to make GB WiFi to work on ICS kernel...
[Xperia Arc Android Development] Iqbal Ansari:
Does this kernel supports swap.

Is there a inbuilt menu to enable or we have to use swap app.
[Xperia Arc Android Development] 1stichiban:
if you're referring to swap partition => YES it does, you need an app/script to enable it.
[Xperia Arc Android Development] DominikHolecek:
Zram is automatically enabled by the kernel, so you don't have to use any app, you can edit it over lupus menu or script ...

Edit: Sorry for confusing, my mistake ... :silly:, yeah for swap use some app like swapper 2, or script
[Xperia Arc Android Development] gu5t3r:
Don't confuse zRam & Swap...
[Xperia Arc Android Development] DominikHolecek:
Sorry for confusing, I didn't read the post thoroughly and I thought that he want to edit swappines ...
[Xperia Arc Android Development] Iqbal Ansari:
So do you guys advice me to use swap or zram at 60 mb is enough.
[Xperia Arc Android Development] gu5t3r:
Well, what I figured out is if you use zRam UKSM doesn't help so much as zRam is already compressed...

So use zRam 64 MB

Or if you're using UKSM rather use 64 MB of swap on 3rd mSD partition...

If you're using Mounts2SD you can select to move Google Play download directory to SD-EXT, and then you can Swap to /cache partition...

That is what I use... UKSM + Swap2Cache (64 MB)

You have Swap2Cache init.d script somewhere on xda...
[Xperia Arc Android Development] Iqbal Ansari:
So basically you are suggesting either use zram or swap + UKSM.

Currently I'm using Zram + UKSM.

Let me try what you suggested.
[Xperia Arc Android Development] gu5t3r:
You can use zRam + UKSM, but UKSM is more effective with Swap... Because zRam is already compressed and UKSM can't compress it further...

When using Swap + UKSM, UKSM can compress almost as zRam but it does not use extra ram like zRam...

64 MB of zRam uses about 25 MB of ram (zRam compression ratio is 2.0-2.5), so it saves you 39 MB of Ram

UKSM constantly saves me 20 - 40 MB of ram

With UKSM + Swap you can use full 355 MB of ram

With UKSM + zRam you can use 330 MB of RAM as that 25 is always reserved for zRam
[Xperia Arc Android Development] Iqbal Ansari:
Thanks for making it more clear.

I avoid swap as I feel it makes my device slower.

Anyways what swappiness value and size do you use.
[Xperia Arc Android Development] gu5t3r:
Swappiness: 33

It's because people usually make swap partition too big for Android system to handle... I use 64 MB...

Swap is slower because ram is 1000 times faster than Flash/Nand memory. There UKSM helps because it saves almost as zRam and you still have 64 MB of swap + you can use full RAM when you run games...

Don't know why Mobile industry made same mistakes as PC industry with first PC's... They all should have more Ram rather than CPU speed...

Even 10 years old PC with 800MHz processor will work fine for common usage with 2GB of ram...
[Xperia Arc Android Development] Iqbal Ansari:
I agree with you.

Our device's processor is perfect it just lacks RAM and where all the lag begins.

I was about to make swap size of 256 mb but now I will go for 64 mb.

I'm running UKSM at normal, is it ok.
[Xperia Arc Android Development] gu5t3r:
If it eats too much battery use low until new version which will have ability to turn uksm off when screen off...
[Xperia Arc Android Development] Iqbal Ansari:
One more thing that can we use zram and swap together?
[Xperia Arc Android Development] gu5t3r:
Yes, but swap spaces are ordered by priority, so if zRam has higher priority system won't use swap until zRam is full...

...and if swap has higher priority system won't use zRam until swap is full...

So, you can, but that is not recommended...

As I said, my opinion is that is best to use UKSM + Swap (64-128MB; 64MB preferable)

If you want I can update ARC GB kernel ramdisk to have new UKSM options?
[Xperia Arc Android Development] Iqbal Ansari:
That would be cool but I dont have a ARC I have a PRO.

---------- Post added at 09:07 AM ---------- Previous post was at 08:52 AM ----------

@gu5t3r

hi I need some clarifications.

I don't want to use swap2SD, but rather swap2cache. <<is this the init.d script I'm looking for? just copy, apply 777 permissions to init.d?

..in orders of magnitude zRam is faster than swap2cache, but swap2cache saves more RAM?

..do I need mount2SD to make swap2cache work? this will be my first time to use mount2sd. lol
[Xperia Arc Android Development] gu5t3r:
LuPuS-GB_v2_ARC_R1.rar - 6.47 MB

It's the script, but edit it to lower swappiness and rather put it to boot.d not to impact boot time...
[Xperia Arc Android Development] Iqbal Ansari:
Thanks man you are great.

Currenty using it with UKSM at normal + 64 mb swap.

A lot of apps in the background and still free RAM left.
[Xperia Arc Android Development] zgmfx20:
I edited it, swappiness now set to its default value 20, placed in boot.d, and it worked.:good:

But when I played Real Racing 3, @ first start of the game, it works fine and has no lag. But when I open the game 2nd time, the phone had a sudden reboot to LuPuS logo. I'm using UKSM(Normal)+swap2cache(64mb) in this instance.

But when I enabled zRam, along with UKSM and swap2cache enabled, it's now working fine for every start of the game. But takes a long delay.

What are your suggestions bro?

Thanks a lot. :cheers:
[Xperia Arc Android Development] gu5t3r:
Are you sure it's because swap2cache?

Can you test again?

As I said there is no point in using both zRam and swap....
[Xperia Arc Android Development] zgmfx20:
Yes i used swap2cache+uksm in first instance. After exit,"free" in terminal reports 30mb used over 64mb of swap. Starting the game again leads me to sudden reboot.

2nd instance: zRam+swap2cache, a bit of delay starting game. After repetitive play and exit, it works fine. "free"=60 to 70 mb, used, minfrees option 7 as u suggested

I guess its from hogging ram from systemUI and framework-res because mine is heavily modded. A month ago with both stock, zram+uksm works perfect
[Xperia Arc Android Development] Vishalkris:
the swap file u r referring to is created by Swapper2 app or your app Mounts2sd???

if its mounts2sd..the app dosnt have any option to select the size of the swap...:(
[Xperia Arc Android Development] 1stichiban:
You are correct, swap file size could not be set using mount2sd. This app could only mount the swap partition of the sdcard.

Swap file size could be set using Swapper2, swap partition size could be set in CWM or minitool partition wizard :)

But what gu5t3r is referring to is android uses swaps based on priorities...
[Xperia Arc Android Development] Vishalkris:
for me its ok if GB-Wifi files dosnt work on the ics...but if we have a kernel like this...(idea started by famous kernel creator D00mlord)..it would be awesome...!!
[Xperia Arc Android Development] Iqbal Ansari:
What is swap2cache.

I tried to search but couldn't understand.

How is it different from SD card swap partition.

[Xperia Arc Android Development] Kocane:
Wedgess, are you gonna be able to unlock same amount of RAM as on ICS? I love this kernel, but it is kinda missing the extra RAM that I saw in your ICS/JB kernel :/...
[Xperia Arc Android Development] gu5t3r:
Instead of swapping to extra partition on SDCard, a swap file is created on /cache partition and linked with loop block... And then you are using that file on /cache i.e. /cache/swapfile for swapping instead SDCard...

This is useful if you are using M2SD or A2SD to have less overload on SDCard...
