flash kernel + wifi module.... still can't use wifi

thank you :good: for your hard work

wait wifi fix for next update
[Xperia Arc Android Development] askaguilr:
Hi, this kernel still have the touchscreen bug, it is present in Stock and CM kernels for ICS, it didn´t happen in stock GB, when you drag something it does big jumps, I mean it moves every 9 pixels, in GB stock it was every 2px, it really makes the mk16a look choppy when actually its only a touchscreen driver bad parameter, this only happens in mk16.

I´ve found a rom with a kernel which fixes that but it's pretty outdated: http://xdaforums.com/showthread.php?t=1695236

I have checked source of stock kernels but I still cant find where to change those parameters to make the screen responsive as before. I have even fond the parameters for galaxy SII in their source but I cannot find them on the mk16, here is an example of what im talking about http://code.google.com/p/freexperia/issues/detail?id=493
[Xperia Arc Android Development] Dexxmor:
For me It moves the 2 px, i never had any issue with your Problems. Eventually your Phone has a Hardware damage.

Could help if you try wiping dalvik/cache first or even reflashing the rom, since it's only you so far with this problem.
[Xperia Arc Android Development] wedgess:
I know WiFi isn't working and I'll keep trying to fix it. Any other devs want my sources to try get it working PM me. But if anyone is using this tell me and I'll update this kernel to my most recent for sources for the play, built with LINARO already notice a performance increase with it. Hit THANKS and I'll start compiling if there's more then one person using it
[Xperia Arc Android Development] Dexxmor:
Great news :good:
[Xperia Arc Android Development] :
Testing CM10 during the day today, I will definately test it if you upload the new kernel with the new WiFi fixes. Thanks for the work so far.
[Xperia Arc Android Development] MrMmmkay:
Are you planing to upgrade your Kernel(s) with the new .587 sources (when they come out in near future)?

Any news about wifi? Tested your Kernel some days without wifi, and i must say that it is realy stable an usable, i would be so happy when you can fix wifi and update the Kernel with the features of your Play Kernel :).
[Xperia Arc Android Development] dympy:
I think I can answer some of these questions!

I'm working together with Wedgess to try and test out several ways of wifi fixes (I've tested about 10 different versions now?) and he's going to teach me how to compile kernels, as it could be something with his build environment.

I finished my ubuntu install with all drivers and git, so now all I need are the toolchains and I can give it a shot (I believe, never compiled a kernel before, but we'll see how it goes :P)

Going to give it a shot tomorrow and over the weekend, because today I'll be quite busy trying to retrieve long lost grades I kinda need for my internship (As in, if I don't have them I'm f***ed and I can't finish college..).

So yeah, maybe Wedgess can explain a bit more about the new .587 sources, because I honestly have no clue..

Dympy.
[Xperia Arc Android Development] siddardha21:
guyss. this kernels looks pretty good. please update this kernel with the play features. eagerly waiting. cheers!!
[Xperia Arc Android Development] wedgess:
Wasn't planning on it but suppose I could when they come out. As Dympy said he's going to help trying the wifi, if I had the device I could keep trying but unfortunately I don't so its going to take longer to get it :( but with Dympy helping it should get moving quicker :) and then hopefully a fix:victory:

Ye i'm going to sometime tonight i'd say, won't mod recovery though until wifi works:cyclops:
[Xperia Arc Android Development] MrMmmkay:
Nice to hear :).

When i can help you with testing or something just say it, i am glad when i can helb getting development for pro straight forward :D.

wifi isn't working on uHD 3.0.1, even after a reboot !

i used the second link as the first is for zelly cream only..

Edit: well... wiping cache and dalvik cache solved it,lol

I spoke too soon :D :p
[Xperia Arc Android Development] lo2ay:
WiFi is broken again, I had to reflash my rom, when it booted, Wifi didn't work so i rebooted, again nothing. Then I wiped cache and dalvik cache, still nothing.

I did the same thing so many times i stopped counting :eek:

I even reflashed the kernel.

Any ideas ??
[Xperia Arc Android Development] atmos929:
that's odd... I am using lupus v10 on uHD 3.0.1, WiFi works fine... when installing ROM do you do full wipe?... including format /system ?
[Xperia Arc Android Development] lo2ay:
Re: [PRO][KERNEL] LuPuSv10 [LINARO 4.7.3][STOCK ICS/GB][UPDATED 26-02-13]

Here's what exactly happened, I was replacing the Xperia JB launcher with the GX one, it had three apks, I marked them the copied them to /system/app. The phone hanged after the first apk was copied and then the phone restarted and went to a bootloop. This happened to me before and I fixed it by reflashing the Rom. So I reflashed it again, but when I booted I found out that WiFi didn't work. Then I kept rebooting, wiping cache.... Etc etc.

About formatting system, the updater-script of uHD already has a command to format system before installation, so I skipped that part. I also selected upgrade on Aroma.

Right now I reverted back to Lupus V9, the best kernel for performance :D
[Xperia Arc Android Development] dympy:
Re: [PRO][KERNEL] LuPuSv10 [LINARO 4.7.3][STOCK ICS/GB][UPDATED 26-02-13]

Everyone with Wi-Fi problems, have you tried using the lupus script? I'm currently creating an app for wedgess, so users can use that for easier control, but it won't be finished anywhere soon, maybe at the end of this week a first beta.

Dympy.
[Xperia Arc Android Development] ezro:
I can't use wifi. I did a full wipe (wipe /system partition included) installed a clean MiuiV4 ROM and can't use wifi.

I also used lupus script option "RESET" but nothing changed...:crying:
[Xperia Arc Android Development] dympy:
Re: [PRO][KERNEL] LuPuSv10 [LINARO 4.7.3][STOCK ICS/GB][UPDATED 26-02-13]

Hmm.. Odd..

I'll make a backup of my self compiled cyanogen mod 10.1 and will flash that same room, take a look at some logs and report back.

Dympy.

Edit:

Also, during tests, I sometimes had to reboot multiple times after doing the reset option.

So it went like this:

Boot, observe Wi-Fi isn't working, use the reset option of the script, reboot, observe Wi-Fi still isn't working, reboot again.

Do note, I didn't write anything during these reboots.

For the lupus menues try this:

su

sh

sh lupus

Zram is not working on UHD, Because the init.d script is using xbin folder change it to bin.

This kernel is great stable fast and battery friendly, but have some little issues.

Aroma installers display only half screen.

Wifi is no detected on first boot of the rom u have to reboot it.

The kernel boot at 800mhz so is a little slower.

[Xperia Arc Android Development] abinash:
it is my first time to flash kernel in fastboot..

if anyone guide me how to flash this kernel on my pro?
[Xperia Arc Android Development] Madaditya:
This

For custom kernels

Get flashtool from the sticky thread..

install proper s1 flashboot drivers..search for it

then

1.Connect your device to your pc,Reboot and during startup press and hold the 'options' button i.e the one to the right of home :P

2.A blue notification light confirms you are in flashboot mode.

3.In flashtool press the 'flashbutton' and then go to flashboot mode...

4.Select 'Kernel to hotboot' and flash the XXXX.img..device should start with the boot logo atleast...this confirms the kernel [boot.img usually] is compatible

5.after this you can choose 'select kernel to flash' and flash!

For stock ftf kernels

its quite easy :P

1. Go to C:/flashtool/firmwares and delete everything there

2.place your .ftf file there

3.GO to 'Flashmode',connect your device and flash!

HIt THanx IF this helped

Coz,THanx speaks louder than posts!

Wow i cannot beleive u made it GB compatible! Amazing how you can impress us, big fan of your work here.

Currently im testing your kernel (no wifi as spected) and comparing to Riyals 1.11

Im using antutu, same config but no sd card IO test. Never labs conditions, but tryed too keep same conditions to see tendencies.

These are just 3 of the various series of runs, other runs werent significantly relevant:

----------------------------------------------------

Riyal KERNEL GB 1.11 (1.0GHz)

RAM	513/534/595

CPU integer	662/735/736

CPU float-point	282/305/314

2D graphics	510/515/543

3D graphics	2001/1806/1945

Database IO	295/410/405

4263/4305/4508

----------------------------------------------------

LUPUS KERNEL GB (1.0GHz)

CPU integer	738/735/736

CPU float-point	310/310/315

2D graphics	512/522/526

3D graphics	1771/1818/1705

Database IO	340/365/395

4224/4297/4216

Something interesting is to find almost the same performance with both. Shouldnt be a great improvement with linaro?

When i tested your previous versions i got a substancial improvement with ICS (didnt have enought time to test ICS using v10)

Anyway, im still impressed for this GB version

High Battery usage on 3g

I like the kernel very much but I have a question/problem. Everytime when i have activated 3g on my Xperia pro has a battery usage of about 10% an hour, if i am in a w-lan it has less than 1%. This happens with different roms, so i think i should be kernel related. In "Settings/Akku-Usage" the "Android OS" is shown as responsible for the usage...

Does anyone has a solution or idea beside switching to 2g? Or are more infomation needed?
