this is not a ROM hehehe... Please try with a clean install of the Kernel... No one has reported such issues :)
[Xperia Arc Android Development] alfiemenace:
i mean kernel haha sorry. wait, what do you mean by clean install of the kernel? :) is it like flash kernel, then clean install of the rom? :)
[Xperia Arc Android Development] jimbo77:
Exactly :)

Flash the Kernel, Boot into CWM, Wipe data and Cache Partitions, Flash the ROM and the reboot the phone :)

If you find any issues after that let me know.

Regards,

Jimbo
[Xperia Arc Android Development] rikigalazy:
Thanks

I've used this kernel a month ago and it has run smoothly.

I switched to other kernels but I always went back to ArcKnight to have smoothness and stability.

Currently using MooDedICS with ArcKnight Kernel. The best combo ever. :good::fingers-crossed:
[Xperia Arc Android Development] jimbo77:
Thanks for the feedback!

Which version are you on now?

Stock-Based or OC'ed one? Also what's your CPU Governor?
[Xperia Arc Android Development] Daniel D.:
I finally unlocked my bootloader and installed your kernel. How or where can I change the CPU Governor etc.?
[Xperia Arc Android Development] jimbo77:
If you want to change only CPU Governor and IO Scheduler try with:

No Frills CPU

Voltage Control

Both are free on the Market :)

Thanks and make sure to provide some feedback ok?

Regards,

JIm
[Xperia Arc Android Development] Daniel D.:
Of course! I'm so happy that I made it...

I'll install some mods and report back. Oh, it seems that I've to install the WiFi modules everytime I installed a new ROM, right?
[Xperia Arc Android Development] jimbo77:
Yes, since everytime you flash a new ROM the wifi modules get overwritten.
[Xperia Arc Android Development] Daniel D.:
Ok, because I'm very new to kernel flashing, I hope I can help anyway.

Phone Model: LT18i

Kernel Version: Stock

Max Frequency: 1402 MHZ

Min Frequency: 245 MHZ

Governor: ArcKnight_II

I/O Scheduler: noop

Network: 2G

Rom: KA20.1 ICS

It feels that "noop" is slightly better than "sio". I've to admit that I didn't try another one. The phone is smooth and CWM works as it should. Waking up the phone is a little bit slower than with stock, but it was mentioned in many posts before and doesn't hurt so bad.
[Xperia Arc Android Development] alfiemenace:
Did exactly what you said, I flashed kernel, flashed baseband 70, boot to cwm, flashed rom and bb libs, boot, changed clock to 24hr, reboot to recovery, flashed rom control patch, booted, installed link2sd the created mount scripts, reboot, restored my apps via TB, reboot, set cpu to 1.4/122 arcknight governor and noop. Still experiencing random reboots :(
[Xperia Arc Android Development] jonxz:
I tried 3.3 stock from OC kernel, not much difference with OC so far except getting random reboots (4 times in 2 days, once when device is sleeping screen off for a while )

Arconium MIUI 2.5.18 / sio / 122Mhz - 1.4GHz / ArcKnight_II / LT18i
[Xperia Arc Android Development] arpith.fbi:
which governor are you using? most probly kernel panic
[Xperia Arc Android Development] alfiemenace:
So it's different with me, I'm on OC kernel and having random reboots. It annoys me :( no time to re flash stuffs again though :(
[Xperia Arc Android Development] jimbo77:
Yeap... Most likely Kernel Panic... Maybe related to the VDD Levels lowered... I forgot that not all device react the same with lower VDD Levels.

If you are using the OC version please try this temporary FIX. I've lowered the VDD Leveles probably too much and that's the reason why your phone keeps rebooting and going into Panic atacks...

This .zip should restore the VDD Levels to a safer ones so it should fix the random reboots...

I'll fix it by next release of kernel.

Thanks!
[Xperia Arc Android Development] alfiemenace:
Still having reboots. :(
[Xperia Arc Android Development] jimbo77:
Can you give me more details on when/how the reboots happen??

for example, you are listening to music, and downloading something and playing at the same time etc...

Also if you can grab a logcat of the issue it will definetely help me to find the solution for your problem.

Thanks!
[Xperia Arc Android Development] alfiemenace:
it happens randomly, when i send an sms, tweet, browse my files, etc. even when i wasn't using my phone. :| sure, but can you teach me how exactly do create a logcat if it happens randomly? i can't even recreate the reboots.
[Xperia Arc Android Development] SXUsr:
Decided to come back to stock and settled on using this kernel, the only thing I don't like so far is the boot image so have tweaked it a little...

...thanks.
[Xperia Arc Android Development] Daniel D.:
:eek: :D :good:

Add his name below it and I would vote 1.000.000 times for adding this into the kernel.
[Xperia Arc Android Development] SXUsr:
We know who made it and where it comes from, maybe it was just the font which is why I removed it. Let me see what I can do.

What about this?...
[Xperia Arc Android Development] Daniel D.:
First we've to ask him! ;) It's great!
[Xperia Arc Android Development] SXUsr:
Thanks, I'm going to mod the boot.img and use it for personal use anyway but would be great if it was incorporated.

FAO jimbo77, no wifi on RC3.1 after flashing modules?
[Xperia Arc Android Development] Daniel D.:
Use the newest test release 3.3 with WiFi. It works.

Perhaps he'll add it to the official release. :fingers-crossed:
[Xperia Arc Android Development] SXUsr:
Thanks! It was the "test" in the name which is why I chose 3.1. Was just seeing how it might look with the Batman font, but changed Arc to SonySketch as it didn't look right in all caps...

...time I got on with setting up my phone, and changing as much Blue as I can to Green. :)
[Xperia Arc Android Development] xtacy!:
@XperienceD,

Haven't seen you around in ages. LOL! Did you change your phone?

[Xperia Arc Android Development] SXUsr:
Hey xtacy :) No lol, I just didn't have the time, in turn I kinda lost interest, but custom ROMs and Android have been doing my nut in lately (to the point I'm considering an iPhone lol), so have decided to go back to stock, hence this brief return. :)
[Xperia Arc Android Development] xtacy!:
Noooooooooo, not the iPhone......nooooooooo :D
[Xperia Arc Android Development] arpith.fbi:
only thing we have to admid about iphone is its camera...you can really see the difference :)

Hi Jimbo

flashed your RC 3.3 Stock yesterday. What can i say? It´s the best kernel i ever had. My phone has never been as fast and smooth as now with Arconium 4.0. No need to OC. Perfect! Thank´s a lot!
[Xperia Arc Android Development] 4thMARCH:

Thanks!
[Xperia Arc Android Development] jimbo77:
Shame on you! That's the phone that hasn't to be named lol... Iphone?? at the moment no thanks! It has a smaller screen and I can't do what i Do for Android... I love the freedom of Android running on my Sexy Arc :D

I haven't had time, kinda bussy at work due to End Of Month reports and so... Probably I'll push stable releases of both Stock & OC'd next Wednesday when all this madness at works has ended :D

Thanks for the Feedback I always appreciate, good to hear it has almost no issues for you :D

It's the data speed that's frustrating when at work, my mates 4S has loaded YouTube and can be half way through a video before mine has even loaded up. :crying: Back on topic, already loving the battery life on this kernel and loving being back on a stock ROM, I'd forgotten what a pain it is to mod though, too many "semc_" files lol.
[Xperia Arc Android Development] sirkay:
@jimbo what BFS version you implemented in your kernel before? ive tried 318 patch for 2.6.32 kernel, no error but when i try to flash it stuck at bootlogo (freeze, have to pull out batt)
[Xperia Arc Android Development] jimbo77:
Glad my Kernel is working good for you :)

It was the 313 and ck2 patch set for 2.6.32 but it caused slowdowns and sometimes made the phone unusable... That's why I removed it...
[Xperia Arc Android Development] Gajba:
I just flashed 3.3 test stock. Which app should i use for undervolting? I tried voltage control and incredicontrol and both doesn't support undervolting with this kernel.
[Xperia Arc Android Development] jimbo77:
Did you read the changelog???

Stock has no support for the moment for controlling VDD levels. It will require modification of the CPU driver . I'll add it later probably.
[Xperia Arc Android Development] Gajba:
The link for test kernel changelog on first page opens the changelog for RC3.

edit: ok i found features of test kernel in post #794
[Xperia Arc Android Development] sirkay:
i succeed implemented v0.318 for 2.6.32. if you want, i can pass it to you tomorrow
[Xperia Arc Android Development] jimbo77:
Let me know if it doesn't cause any slowdown or something...

Btw did you add BFQ IO Scheduler? It should give a boost in combination with BFS :D
[Xperia Arc Android Development] sirkay:
caused of slowdown maybe its not good at multitasking. it only focus on foreground process. so far ray users said its smooth. its still fresh, just 4hrs ago i built it.

right now im using cfq io. tried build before with bfq but got error with filemap.h
[Xperia Arc Android Development] jimbo77:
Ok if you can just send me the patch for the BFS and I'll see if I can build the BFQ IO scheduler :)

[Xperia Arc Android Development] Google fetishist:
is it working? cuase im using the 3.1 stable rom? does it fit ?

After the installation of the ROM, should I boot it one time then go back to CWM or is it possible to flash the wifi fix in same session as installing the rom ?

EDIT: i tried 3.3, but still not working

probably it is my baseband ?!

And yes, i ever wiped the system and freshly installed the hole rom and THAN flash the wifi fix. or must i flash the kernel again to ? i did it but doen't change anything pls help me guys i really don't know my fault

In Wich order i have to do this:

-clear all data

-install rom

-installkernel

-install fix

pls can you give me a little advice in wich order i should do and if there is any trick HOW i must do that. i'm a beginner in it

I use Arconium ICS 4.0 and everything is running nice and smooth with this kernel. Battery life is highly improved with this update, especialy in deep sleep (48+ hrs). It would be great if you add support for undervolting CPU to get even more battery life.

The only problem I have is that sometimes I can't answer (or refuse) the incoming call. In this case i have to turn screen off and back on to anwser the call. I don't know if it's ROM or kernel related, but i never had this problem with other kernels. But it's not a big deal because it happens only once or twice a day.

Keep up the good work jimbo!

[Xperia Arc Android Development] ArcMan09:
So which version of 3.3 shall i use.?

Stock one or overclocked.

:confused:

Because i want better battery life & performance on Arconium ics v4
[Xperia Arc Android Development] shunkawakan:
Try the stock version. It's awesome fast with good batterylive. My phone has never been as fast as with this kernel. No need to Oc. As governor use ArcknightII.:-) You will love it!
[Xperia Arc Android Development] wth_is_life:
Can anyone sum up what are the errors on 3.3 again please ?
[Xperia Arc Android Development] eawert:
I totally agree! Superb battery life.
[Xperia Arc Android Development] killer86th:
I had exactly the same problem since Arconium 2.4 up to now 4.0 with other older kernel (stock, older version of Arcknight), therefore, I believe that problem is ROM related (stock ROM problem or Arconium problem idk).

Arcknight 3.3 test is clearly the best kernel i have ever tried in this forum: smooth UI, awesome battery life (comparable to stock kernel). In addition, my Arc S got better phone signal than before (I'm working in a high building with low phone signal), idk how you did it, but thank you very much.

Anyway, the only problem in this kernel that catch my attention so far is a stutter/lag when receiving phone call (it seems that the phone react a little slowly when wake up and receive the call), but I can live with that. I also got a little lag in opening phone book/sms/calls, but I think it is ROM/themes related too.

is it safe for xperia arc.

for keeping its frequency to 1.2 ghz by default always or else.?
[Xperia Arc Android Development] jimbo77:
Any Amount of OverClocking may affect your chip life.. The thing here is how much it decreases it, using a 20% of OC is one of the lowest damages you can have and if you combine it with UnderVoltage it gets reduced even more.

I'll say that having 1.2GHZ is not that bad and will not harm that much your device...
[Xperia Arc Android Development] ArcMan09:
Then Should I Clock My Arc To 1.2 Ghz By Default .?

JImbo.?

because I Dont Want To Damage MY HArdware.
[Xperia Arc Android Development] jimbo77:
If you don't want to harm it at all, you should use Stock Firmware and Stock Kernel but if you're willing to sacrifice a litle bit of Chip life in regards of performance, speed and stability then you can OC your phone up to 1.2GHZ.

Again, it WILL decrease your Chip's life but it will be so little than won't even be noticed :)

ArcKnight RC3.4 - OC TEST

Hi Guys!

It's been a while since I updated this Kernel (:p)...

Let me recall what the lastest issues were:

A bit of Lag when Answering a Phone Call

Screen took like 1~2 Seconds to Turn On when deep sleeping

NO USB-OTG Support

So if I'm right those were the only issues found on my RC3.3 TEST Versions, plus Battery life seemed to be very good on both Stock and OC Versions...

Well based on your Feedback and on my own experience I've worked on a new version that will try to address those issues :D

Changelog:

Added Back BFS Scheduler

Added Back BFQ IO Scheduler

Removed 122MHZ Freq, it was replaced with the 245MHZ to avoid slowdowns

Attempt to add USB-OTG Support for Mouse, Keyboard and Storage

USB-OTG Modules:

This are the modules specific for my kernel configuration, since I have no access to a USB-OTG Cable I Can't garatee that they will work, I need the users that actually have that cable to confirm wheter if it's working or not...

The procedure to load the modules should be the same as per any other modules:

Move the desired module to /system/lib/modules

Open up Terminal and do: insmod /system/lib/"name of the module"

Test if it's working

If you want to autoload the modules then just put a file in the init.d folder containing the line above and save it.

Download Links are added to Third Post... I'm moving the RC3.3 Test Version as "Stable" Ones to 1st Post in case you find any issues :D...

Please test and leave any feedback you can :)... And if you feel like helping or supporting my work don't hesitate on Clicking on the "Donate" button :D I'll really appreciatte it :D

Happy Flashing and Testing!

[Xperia Arc Android Development] jimbo77:
There is no Update for the "Stock" Based version yet... It's more complex and I have not enough time to update the 2 Kernel Versions...

An update will be done but not right now, I'll probaly do it during the weekend if I can to add the latest changes to it as well....

BTW: USB-OTG should work for both versions (RC3.3 and RC3.4).

[Xperia Arc Android Development] OmarBizreh:
gonna try out 3.4, but I was wondering why on each update for the kernel there is an update for the wifi modules?! :confused:
[Xperia Arc Android Development] jimbo77:
Not for this one... RC3.3 Wifi Modules should work on 3.4 as well... Previously I used to change the Kernel String Name which made the previous Wifi Modules unusable since the modules are compiled with one specific configuration.

I tought of that so I decided to keep the same string name from now on and the wifi modules will be the same, I just left the link there to avoid confussion around members :D
[Xperia Arc Android Development] OmarBizreh:
Thanks for clearing it up :D I was waiting for your answer before I post another comment asking why the 3.4 wifi modules link shows me the 3.3 wifi modules on mediafire :P
[Xperia Arc Android Development] alfiemenace:
How about the random reboot problems for some users?
[Xperia Arc Android Development] jimbo77:

Hey guys,

3.4 is out and i would like to upgrade on this Kernel Version, but i got one question.

can I over write it easiely without cleaning the cache and so on? because i would lost all my apps, and i got a lot, and a lot are more than 100 apps. downloading all and set it up costs me days.

so is there any chance to keep my data alive ? i mean, a official Sony ics update doesn't kill any app at all, so i think its possible by custom kernel to, am i right?
[Xperia Arc Android Development] jimbo77:
Of course... Flashing a new Kernel doesn't delete any app BUT just keep in mind that if any sudden weird errors show up it might be related to the fact that you didn't do a clean install of both Kernel and Rom and that might cause some left overs and conflicts :D

Give it a go and if you find any bug let me know.
[Xperia Arc Android Development] arpith.fbi:
cannot download USB-OTG modules folder..can you rar it and upload if you dont mind? :D
[Xperia Arc Android Development] Google fetishist:
okay if it crashes, is there any chance to play back a Nandroid backup ? so I got a slight chance to save my apps because i allready invests hours and days to get kernel 3.3 PLUS wifi working. if i can't save it this time thats it with arcknight, its not your fault, you don't programmed android but this stress once again? now way ! ;)
