I solved problem with not working GSM in my phone on KA21. I had enough space in internal memory, after uninstall/move to SD some apps all works. :)

Thanks guys for the tip with Dalvik cache size - works great.

I fixed LEDs brightness bug - again. Script is attached to post.
[Xperia Arc Android Development] Overdose1986:
Any solution to root-superuser bug?
[Xperia Arc Android Development] dbox:
After install Framework mod add-on from first post button LEDs are permanently off. This app is designed to Neo V, maybe this is a problem?

Credential Services Manager crashes for every reboot.
[Xperia Arc Android Development] jonxz:
Did you try to remove the Dalvik cache from /cache/?

Both /Cache/ and Dalvik cache maybe full, if /cache/ full there will be lots of FC problem.

You can check the available space in /cache by (connected to PC and run) #adb shell df

sevoir created an update script above you may want to try, or remove the /etc/init.d/02dalvik manually.
[Xperia Arc Android Development] sevoir:
my script only increases dalvik cache size.
[Xperia Arc Android Development] jonxz:
Actually not "incrase" the dalvik size... it just put the dalvik cache back to /data partition.

df -k /cache | tail -n1 | tr -s ' ' | cut -d ' ' -f2 --> get /cache size, in my arc should be about 103936

Before it is being edited if cache size is larger than 80000 then it will mount the dalvik under /cache, i.e. share the storage space with /cache, that means if dalvik cache is full, /cache will be full too.

Some apps will not run if /cache is full, and apps cannot be installed if dalvik cache is full

If 80000 is modified to 180000, which make the first if statement false, which mean skipping the whole script, which is same as deleting the file from init.d. This will let dalvik cache in the same partition as /data, which is about 4 times the size of /cache (430080).

So I suspect Films keep getting FC is due to /cache full... ;)

Please help me,...

I'm newer for this section Guys. I'm using 2.6.32.9-Arc Knight_Kernal_RC3.1.

Build number JJHyb_v3.1

can I use this rom(KA21).

flash with CWM.

I downloaded this rom. I'm waiting for your answer. :rolleyes:
[Xperia Arc Android Development] sevoir:
I think yes, but I'm using DoomKernel with cwm modules.

Please read first post.
[Xperia Arc Android Development] jonxz:
I think the WiFi module does not work in Knight_Kernal_RC3.1....

I am using ArcKnight Test 3.3 now... Working very well~
[Xperia Arc Android Development] Subo_it:
Is that method correct?

ThnX guys, I'll flash DoomKernel kernel, then flash this rom.

Is that method correct?

:confused:
[Xperia Arc Android Development] sevoir:
Make backup your system before.

Yes, flash with DoomKernel

download DoomKernel cm9 modules to sdcard .

put KA21.xx.zip to sdcard

and do it factory reset, wipe dalvik-cache

Update with KA21.xx.zip (no requires at flashing end)

Update with DoomKernel cm9 modules.zip too

And restart and please patient at first boot.

This process work my phone (ARC S)

[Xperia Arc Android Development] Daniel D.:
First of all: THANKS for this awesome ROM! :victory:

After trying different ROMs I saw KA20.1 and was captured by it's nice lockscreen and content. After KA21 was released with it's nice new apps, I decided to use it on my Arc S. Two weeks passed and I had to mod it a little bit to fit all of my needs :o. This is the result of a custom installation without any additional installed mods except the Kernel WLAN & Quickpanel (also modded :D) and I'm very happy with it!

Thanks for your effort krabappel - this is a nice one eehh... the best one!

Anyone else got this too???

[Xperia Arc Android Development] Monkii:
First of all, very nice+smooth ROM you got here!

Nice fix on that play store problem and that LED being too bright!!

However, I still got one problem which hopefully someone can shred light on me...

In the Music app -> sound enhancement, I only get 5 eq levels but the bottom part where the lever for bass should be is blank... Anyway to solve this problem??
[Xperia Arc Android Development] rikigalazy:
Thank you for this rom. It takes so little space and works great and SMOOTH too!

I've been using it for a week now and I've had some problems starting two days ago. I can't install some apps anymore. I have unknown source and usb debugging on.

This is from Flashtool. I also tried to install them from SD card but it said "installation was not successful".

It happened after I flashed your framework. I did try to reset to factory default and it was still happening. I tried to clean the cache too.

Then I decided to flash the rom again and I still get the error. Any suggestion?
[Xperia Arc Android Development] jonxz:
Probably Dalvik-Cache/Cache full problem, DEXOPT is the Dalvik cache for the app.

connect to computer and run

#adb shell df

and see if the /cache and dalvik partition is at 99%

check page 160 of this thread.

or just delete /etc/init.d/02dalvik and reboot.
[Xperia Arc Android Development] linx1287:
how do i install this? i mean do i need to install the stock ICS firmware & then flash this?
[Xperia Arc Android Development] SXUsr:

Is the Xperia S keyboard included in this rom?

If not, will it work when i install the keyboard?
[Xperia Arc Android Development] vjetaa:
Installed and stuck on SONY boot screen.

Somebody any idea?

I'm on stock ics 4.0.4
[Xperia Arc Android Development] Daniel D.:
With so many informations... eehh NO! :rolleyes:

Did you remove the battery and tried again?

Which options did you choose during install?

Unlocked bootloader?

It is included if it's the darker one with the new layout compared to the former one of the Arc S.
[Xperia Arc Android Development] vjetaa:
Yes i removed battery and reboot but still stuck on the sony logo.

Also unlocked bootloader.

I wiped dalvik cache and factory reset like said in instructions.

[Xperia Arc Android Development] Tonyshun87:
I'm really confused that as a new user, I followed the instructions, and got a bootloop, is it because my kernel? which one do U guys recommend?
[Xperia Arc Android Development] jonxz:
Try not to tick "Put Dalvik-Cache in /system" when install

I tried on my Arc S and it stuck on Sony boot screen too...

I am running ArcKnight 3.3 stock
[Xperia Arc Android Development] mo786wp:
Awsome rom guys, just a quick question is there any way of getting the 2 lights between the hard buttons to switch on? i think they wer working but after i flashed the add on then the lights now dont come on. Im sure if i remove the add on it will re apear but i want the reboot,recovery etc. Is there somethign i can flash over this that will make the lights work?
[Xperia Arc Android Development] Daniel D.:
In /system/etc edit the file hw_config.sh and change the line in the # LMU AS3676 Configuration block to your needs:

echo xxx > $dev/button-backlight/max_current

Change xxx to a value. 1000 is low, 5000 is bright. You've to try a little bit. After changing the value save the file and re-boot.
[Xperia Arc Android Development] mo786wp:
Hi thanks again for teh feedback.The current value is 900 so i tried changing to 1000 and 2000 etc but still no joy, still cant get the hard buttong lights to switch one after reboot.
[Xperia Arc Android Development] Daniel D.:
I'll post my file later.

Here is my configuration. The only important lines are the three last ones. Add a "#" before the two lines with "echo 900" and add the third line below them with the given code. It reduces the light significantly. You can add values from 1000 (?) to 8000 - try it out. 2500 is perfect for me - low lights.

# LMU AS3676 Configuration
dev=/sys/devices/i2c-0/0-0040/leds
echo 1,40,255,35,35,1,100 > $dev/lcd-backlight/als/curve # ALS curve display BL [grp],[Y0],[Y3],[K1],[K2],[X1],[X2]

[Xperia Arc Android Development] mo786wp:
Dam not sure what i am doing wrong but just not winning here lol. Copied ur text exact and still gt a issue. Do i need to wide cache or sumthing? I am about to giveup and live without the lights lol.
[Xperia Arc Android Development] Daniel D.:
Try this from version KA20.1:

# LMU AS3676 Configuration
dev=/sys/devices/i2c-0/0-0040/leds
echo 1,65,255,24,24,5,128 > $dev/lcd-backlight/als/curve # ALS curve for group1
echo 2,0,0,0 > $dev/lcd-backlight/als/params #[gain],[filter_up],[filter_down],[offset]
echo 1 > $dev/lcd-backlight/als/enable #Sensor on/off. 1 = on, reg 90h
echo 450 > $dev/button-backlight/max_current

Change the 450 in the last line to something bigger if it won't work.

a newbie here with Android. Spending 4 hours reading, searching, using tools, but still no clue how to install this (or any other) rom.

Can't get in to recovery.

Is there a step-by-step guide for the not experienced people? Can't find it anywhere.

The zip file is on my intern SD. and then what?

[Xperia Arc Android Development] SkVergil:
It seems I can' t fix my System UI. When I flash the ROM and it boots up, the statusbar, wallpaper and other stuff are missing. I tried wiping dalvik cache/rebooting and I still get the same problem. It's been a while since I use KA ROMs but last time, I had the same problem, to fix it I just flashed a batteryfix.zip addon that was provided and got it working. How do I fix it now?
[Xperia Arc Android Development] Daniel D.:
@redgirl

Install Xperia CWM from Google Play and install CWM inside the app. After that boot into recovery within the app. Select the zip file on your sd card and follow the instructions.

@SkVergil

Try to install one of these: http://xdaforums.com/showthread.php?t=1686586. If it doesn't help, flash stock 4.0.4, root it and flash KA21 again. I didn't have this problem.
[Xperia Arc Android Development] jonxz:
I don't have this problem either... I am running ArcKnight 3.3 stock.

Maybe ROM corrupted? Try to download again?

Or you can try a clean flash again:

backup all apps and data with titanium backup. Then boot to cwm, go to "storage & mounts " -> format /system, format /data, format /cache.

Then flash KA21 again (and wifi module if required by kernel ).

Bootup and restore apps and data with titanium backup.
[Xperia Arc Android Development] crismat2001:
What Kernel I can use in this ROM?
[Xperia Arc Android Development] itsbvka:
I had exact the same issue, started with a clean Sony Stock 4.0.4. Global generic, then flashed ArcKnight 3.3 (including full wipe), next KA21 + Wifi. And saw this behavior too. I tried a few times with different settings and with/without framework mod.

The only thing I can think of is that the zip was/is corrupt, so I re-downloaded and re-installed (default settings) same problem again.

One weird thing I see in the install is that there is a changelog for KA 21.1 which I don't see here, might it be related to 21.1??

UPDATE: First installed 20.1 and then upgraded to 21 without a full wipe. Now the notification bar is there.
[Xperia Arc Android Development] jonxz:
I tried:

Stock

DooMKernel

ArcKnight

Personal recommendation is ArcKnight 3.3.stock frequency with Wi-Fi module, great performance and battery life.
[Xperia Arc Android Development] redgirl:
Tnx Daniel! That worked :good:
[Xperia Arc Android Development] Daniel D.:
Great! One of the most useful apps if you don't want to unlock bootloader.
[Xperia Arc Android Development] redgirl:
But the phone didn't boot :( i flashed it again and now another problem. Com.android.phone has stopped bla bla...so sim is not working anymore.

Now trying to repair phone with pc companion, but it takes ages to prepair pc.

Wish i never tried a custom rom. Hope i can still use the arc
[Xperia Arc Android Development] Daniel D.:
You should use Flashtool to "repair" your phone. This Sony crap is awful.
[Xperia Arc Android Development] redgirl:
Getting kind of desperate now:(

Unlocked my bootloader now, but still troubles. keep on getting error: The process com.android.phone has stopped unexpectedly.

and "keypad has stopped"

can;t root anymore, so can't do a thing!

repairing with flashtool....how??
[Xperia Arc Android Development] Daniel D.:
Why did you unlock your bootloader? It has nothing to do with the error.

Please do the following things:

1. Download Flashtool from here - Full Install & Update - and install it.

2. Flash 4.0.4 with root access as described here.

3. Install KA21 with Xperia CWM.
[Xperia Arc Android Development] choovanski:
I'm running on Arc S with Arc Knight kernel, and wow. The speed difference to any other rom I've run is palpable. Simply fantastic.

Still not keen on the Sony elements, and I do miss the aokp rom control, but the speed and the solid battery life really sell it.

Just wanted to thank you for the rom.
[Xperia Arc Android Development] crismat2001:
thanks!
[Xperia Arc Android Development] mr.alawi:
guys just want you to see how the battery life performs with Arckernel 3.3 and KA21 are like

played sonic for around 20 mins ,made few calls,watched videos,listened to musics,used instagram,whatsapp,facebook,twitter,plume for two days and still got 28% left for me :D the best combination ever !
[Xperia Arc Android Development] redgirl:
I did exactly what you wrote. part 1 and 2. so far, so good. BUT...still the same errors and no network :crying:

I rooted, that worked, CWM install went ok. Went in recovery and wiped dalvik cache , did factory reset and now i stopped. it's better to have a good working phone before trying to install this rom. but how do i get it working again? is there a way to totally clean the phone ?
[Xperia Arc Android Development] Daniel D.:
If you flash 4.0.4 it should be clean enough. I mean flash 4.0.4 with 4.0.3 kernel, root and flash 4.0.4 kernel only. After that you've a clean phone except the bloatware ;). I did that so often and my phone worked everytime. After installing any ROM out there it still worked.
[Xperia Arc Android Development] mandarjoshiin:
Best kernel to use with KA21?

Which is the best kernel we can use with KA21? Please help. I had to downgrade to GB when I tried the previous version of KA with the stock and doom's kernel v4 but it made my arc so laggy and slow.. :( So please tell me which would be the best kernel. I dont want OC/UV but a stable rom.. Thanks..
[Xperia Arc Android Development] mr.alawi:
well you can try Arcknight 3.4 Kernel with KA21 it's really good and fast...once i've tried ICS i never ever once decided to return to GB .. ICS is the best !
[Xperia Arc Android Development] jonxz:
In terms of stability and battery friendly I'll suggest you to use 3.3 stock, its a perfect kernel....

I tried 3.4 for a few days but there seems to be some bugs and touch screen scrolling is kinda acting strange.

I am using KA21 too.
[Xperia Arc Android Development] redgirl:
flashed again and tried to do step 3. but same again....it won't start. stops at Sony logo.

Don't know what's wrong with my Arc, but it will end up in the trash :(

All the errors i get, doesn't matter what FW i flash. Contacts stopped, settings stopped, com.android.phone stopped, etc.

Can't use it anymore.

I'm glad i still have my 4S!
[Xperia Arc Android Development] jonxz:
Have u try flashing Sony stock Rom ftf with flashtool? If u have problem with stock probably something went wrong with your phone hardware. ..
[Xperia Arc Android Development] Daniel D.:
Did repairing with Sony tools help you? Strange behavior, it should work with stock 4.x. Did you follow the steps in the given order? Sorry to ask, but it's strange. The problems occur even after flashing the stock 4.0.4? What about flashing Gingerbread 2.3.4?
[Xperia Arc Android Development] cyxjimmy:
Hey guys, I've met a icon display issues. It's the signal issues. In common use, I turned the Wifi off, and the phone signal icon is always gray but I can make a call or send SMS. After I turn on the Wifi, then the phone signal icon turns blue, but it's always full signal, and never turns half or quarters. I don't know why. Wish someone could help me fix this issues or you can just give me some advice. Thank you.

Really really like this ROM. Cheers.:o
[Xperia Arc Android Development] redgirl:
I flashed now with official global fw and thank god it's back to normal!

I did the steps as described. Dont know what went wrong. Only thing now is that i can't update with Sony. Probably cos i unlocked bootloader? But i dont care. I'm happy it works now and not gonna try custom roms again ;)

Btw: can i just install the apk files from the KA21 to get xperia s stuff? Or better not? :cyclops:

I think you'll have to root it and copy the file to /system/app manually, you cannot install the apk file with installer

If you installed 4.0.4 before, you don't need to install it again. Just install KA21 with factory reset, wipe dalvik-cache and format system.

Hi there...

I've installed the KA21 and was coming from JJ'sHybrid. Love the smoothnes and speed. But there is one big issue.

I've used titanium backup to restore apps and their data (not the system ones...) and after getting most of them back I've recieved a message from titanium "app is not installed" ... Also, I can't update OR download anything from google play. Installing manually from sd also doesn't work ;/

I've tried to clear data of google play application, download manager also. Wiped cache and dalvik from recovery. Uninstalled google play updates. Problem persists :/ Each time i try to install something from play i get "package is invalid" info...

I know that full factory reset would probably help, but i'd rather not loose my apps and their data. Especially that i've done the restore via titanium backup many times and never had any issues ;/
[Xperia Arc Android Development] itsbvka:
