I had the same problem. I solved it on my phone. Whit v19 I undervolted whit -100mV and whit v20 I undervolted -75mV. Now my phone doesn't freeze anymore.
[Xperia Arc Android Development] tRippinthehead:
My arc got some random reboots too. But yes, phone more faster then on v19 kernel :)
[Xperia Arc Android Development] Flo95:
Tried that now, too.

I'll report back
[Xperia Arc Android Development] davibs:
Sorry, how to?

I have a lot of freeze :(
[Xperia Arc Android Development] Coolgoly:
You can use an app like incredicontrol or setxperia to manage cpu voltages.
[Xperia Arc Android Development] davibs:
And what i have to do?

Can i do it with SetCpu?

Sorry i'm confused about cpu voltages..
[Xperia Arc Android Development] Coolgoly:
Set cpu doesn't has voltage managing.Try incredicontrol,it's easy to use,any cpu frequency has his dedicate voltage,just tap + or - to increase or decrease it.You need to have a kernel that support this like the awsome doomkernel.
[Xperia Arc Android Development] spit85:
I use Setxperia, to set frequency and voltages. Set the voltages in steps from 25 mV to be safe.

Here are my voltages, whit these settings my phone don't freeze any more. But de settings are different on every phone.
[Xperia Arc Android Development] Coolgoly:
I'm thinking that if his phone freeze on stock voltages the issue is another one.
[Xperia Arc Android Development] spit85:
I agree. Maybe the low memory settings? I set them very aggressive on my phone, to speed him up.
[Xperia Arc Android Development] Coolgoly:
Unfortunately i don't know it,also don't know if he is using V6 supercharger to manage low memory settings.
[Xperia Arc Android Development] spit85:
I mean that he can set the low memory settings more aggressive, so the phone have more memory. Maybe the phone freezes because he is out of memory, when there are a lot off apps running in the background. AutoKiller Memory Optimizer can be used.

Further development

Doomlord, have you seen this? Published an hour ago :)

[Xperia Arc Android Development] DooMLoRD:
Yes already saw and reposted in xperia s forum

Btw Sony have again provided corrupt sources... So again we need to wait for correct working sources...
[Xperia Arc Android Development] Ninolina:
If you remember I had a problem with Flashing v20, as my phone get into a bootloop. When I remove v6 Supercharger scripts I was able to boot up my Phone. Since then I do not have any issues with v20 - not a one freeze or restart of my phone. So maybe v20 is not compatible with v6 Supercharger? Try to disable it...:)

Question for DooMLord...:) Did you change something big in logo.rle in newest version of your Kernel? If try to change logo.rle I can't get into a Recovery or Boot Manager...:( By the way - with v20 the battery life is good as in previous versions and it seems faster...:) Thanks...:)
[Xperia Arc Android Development] spit85:
Is use supercharge update 9 r7c or something like that. Works perfect one my phone whit kernel v20. The bootloops on my phone hat to do whit the voltages, but mybe it is useful for DooMLord that people, whit bootloops and freezes, tell which tuning apps they use. If a specific app is used by more people, then that app is maybe the reason for the bootloops.

So, which overclock tool, or voltage tool? Memory tweak? That kind of things.
[Xperia Arc Android Development] Flo95:
I loweres the UV and had another reboot today on Arconium 7.3

Undervolted -100mV again and so far it runs for 12h atm

Seems like it got a little bit more stable after each reboot
[Xperia Arc Android Development] spit85:
Maybe it's the Rom? I use a generic Rom, flashed whit WotanClient. Have al the phone's whit freezes a custom Rom?
[Xperia Arc Android Development] HellRoot:
I flashed a mod for Xperia mod... It worked on v7 and wanted to try on v8...

After the flash it does not go further than the bootlogo..I used v19... I then tried advanced stock kernel and I could enter recovery to delete all and reinstall.. On v19 I could not even enter recovery... Then I flashed v20... And no change... Why does it not work anymore ? Especially when Advanced stock works....

I loved your kernel
[Xperia Arc Android Development] DooMLoRD:
no nothing changed... there is a bug in the semc bootloader... if the boot.img isnt of correct size then device wont boot...

try the 1.6 Ghz version
[Xperia Arc Android Development] Ninolina:
Thank you for answering...:-) But my device DO boot up it just can't go into recovery it's just skip that part of booting when it should vibrate to give a sign for pressing volume down to go into recovery. Even if I do not wait for vibrate and press volume down all time of booting it still just boot up and not go into recovery.

Thank you very much...:-)
[Xperia Arc Android Development] DooMLoRD:
well then they ramdisk seems to be damaged... u need to repack ramdisk under linux... windows doesnt keep the symlinks intact which is needed for recovery to work...
[Xperia Arc Android Development] HellRoot:
I tried the lower one and now it works again... Weird if you ask me... But thanks. :-D
[Xperia Arc Android Development] irononreverse:
I'm getting a lot of reboots using 20v2 of this kernal. I'm on stock firmware, stock voltages, 134-1.018 ghz, smartassV2 and bfq.
[Xperia Arc Android Development] HellRoot:
Try sio...I use that one with no problems
[Xperia Arc Android Development] irononreverse:
I've gone back to 19 to see if that stops the reboots. I skipped this version after being on 18 so if this one reboots too, then I guess my Arc doesn't like having an overclocked GPU.
[Xperia Arc Android Development] DooMLoRD:
Yes even I have shifted back to v19... I was getting many random reboots on my regular setup... Seems these sources aren't that stable... Oh well back to v19 sources...
[Xperia Arc Android Development] HellRoot:
I have not had one reboot yet... :-) though it has had a few slowdowns... But maybe I will go back as well 0:)
[Xperia Arc Android Development] Grimmyreapzky:
I am getting big problem for installing Achotjan ROM kernel. Previously, I have your kernel (v20) in my arc, after that i reflashed the arc with flashtool into stock again. And then i tried to install Achotjan rom. The first instructions said that i have to flash the boot.img(Achotjan Kernel) using fastboot method, the weird thing is after i turn on my arc, the kernel always get back into your kernel(v20), and its not freexperia logo :/ do you guys have any solution? Thanks for you replies
[Xperia Arc Android Development] Flo95:
Do you type fastboot flash boot boot.img?
[Xperia Arc Android Development] Grimmyreapzky:
Yes i have done it for many times, but the result is always same. Is there any ways to completely remove the Doomlord kernel and get back to stock, so i can change into Achotjan kernel?
[Xperia Arc Android Development] Flo95:
Yes, flash stock ROM with FlashTool
[Xperia Arc Android Development] cx-11:
Hy doom

I have tester this 3 baseband

(.36/.64/.66)

with V19 and V20 lower mod

And I noted that the kernel bothers runner well, snappy and bugless with the baseband (.64)

I am on stock supercharged .62 Rom

Run both kernels on 1,4ghz noop no under, overvolting

I'm happy with this configuration
[Xperia Arc Android Development] HellRoot:
I flashed a totally different kernel... Like the advanced stock kernel and then after that the wanted kernel... I had same problem as you...
[Xperia Arc Android Development] spit85:
Read the first post from DooMLoRD, there you can read how to go back to stock kernel. http://xdaforums.com/showthread.php?p=15728414
[Xperia Arc Android Development] Grimmyreapzky:
Ive tried it so many times, but the result is always same. Do you think there is relation between kernel? Especially when theyre based on FXP kernel Sources
[Xperia Arc Android Development] Flo95:
Then flash a stock firmware with FlashTool
[Xperia Arc Android Development] NecromantiA:
hey and good morning i thinking to change my stock kernel the time is come!

because i am new to this i want to tell me which of the doomlord kernel have the better battery drain.thank you
[Xperia Arc Android Development] Flo95:
Latest versions have good battery life.

I'd say go for V19, because V20 is unstable on a lot of devices.
[Xperia Arc Android Development] luvrilke:
Got a lot of reboots on v20. Maybe the source is not stable. Go back to v19 ^^
[Xperia Arc Android Development] xiqxiq:
Hey dood, I really like your Kernel, but the logo doesn't quite fit the elegance

of the Arc s.

Is it possible to change it?

Or could you make a version with a more standard logo?

cheers,

~xiq
[Xperia Arc Android Development] iridaki:
Doom is using a bootlogo that the community voted for.

Also it is only visible for a few seconds after a reboot.

Moreover, it is a form of "digital signature" of Doom's work. He has every right to make his work distinguishable in any way he wants, since he is sharing it here for free.

Last but not least, there is a thread here on how to decompile the boot.img and change the logo yourself. Check out my threads from my profile.

It's unfair to ask him to spend extra time for such a trivial thing.

[Xperia Arc Android Development] Flo95:
It's a way to show respect for DooMLoRD, also everyone who saw it on my device liked the bootlogo :)
[Xperia Arc Android Development] Muurahainen:
I would like to thank DooMLord for nice work: Thanks Dude!

Are there any other donation methods besides Paypal?
[Xperia Arc Android Development] rashid.fairus:
not the logo that makes this kernel perfect,what inside it that make it damn soo perfect,btw the logo was trademark for doom,cheers doom,you are the kernel expert in this forum:D

stuck at boot

hey there,

i installed V19 of you kernel and the modules for V15 and higher

then i rebooted and my phone stucks at black screen with backlight on..

adb says:

"W/kernel ( 164): Smartass: frequency change failed: 249600 to 245760 => 249600"

I installed over advanced Stock kernel.

What can I do to get it working ?

greetings
[Xperia Arc Android Development] DooMLoRD:
Try the 1.6 GHz version
[Xperia Arc Android Development] mrtsunami92:
Thats what i tried...

"ARC-DooMKernel-v19-BM-v2-lower_boot.img"
[Xperia Arc Android Development] DooMLoRD:
Well try a fresh flash of ur firmware/Rom... Most of the times some init.d scripts/app settings cause such bootloops...
[Xperia Arc Android Development] mrtsunami92:
again Hello,

the Rom I´m using is "MooDeD ICS ROM v50.0",

so i got:

MooDeD ICS 50.0 [AXP]{Full}.zip

NewAdrenoICSSony.zip

ARC-DooMKernel-v19-BM-v2-lower_boot.img

ARC-DooMKernel-v15-modules_CWM.zip

What is the order to install ?

Thanks a lot!
[Xperia Arc Android Development] DooMLoRD:
why are u installing ICS adreno drivers on GB?
[Xperia Arc Android Development] mrtsunami92:
Oh Sorry,

my Fault i wanted to install your GB kernel on ICS -.-' hahahah
[Xperia Arc Android Development] DooMLoRD:
Hey guys just wanted to keep u updated...

The xperia S release, here in India, was pushed back by Sony to mid April... I was able to get my hands on a grey market handset and tested it out... It was **** laggy and design, feel in hand was really disappointing...

Also just today (2nd April), HTC officially announced and launched the One X and One S here in India!!!! I checked out the HTC One X and was really impressed... Awesome device, so light (just like the Arc) and brilliant screen, feel of device.... So I bought it :)

For those confused between Xperia S and One X I highly recommend that u check out both devices in hand before ordering it online...

Don't worry this won't affect my kernel work for Xperia 2011 devices... I am eagerly waiting for Sony to release final ICS for ARC... Let's hope they release the kernel sources soon after the ics update...
[Xperia Arc Android Development] hemo1001:
For me no more sony ... the performance is so disappointing of all of it's devices ... when i got my hand on the Xperia s i found no difference between it and our Arc .... Same UI, Same laggy ICS plus it has a lower speaker volume comparing with the Arc s (A fact)

Edit : BTW congrats for your new device ....
[Xperia Arc Android Development] 28spawn:
Hi Doom, just a question, I didnt find anywhere, this kernel works with the xperia pro? is the same everything so should work, I am wrong?

Kind regards
[Xperia Arc Android Development] eksen:
How we can make the installation for Linux?
[Xperia Arc Android Development] DooMLoRD:
Yups I too didn't find the Xperia S that different especially after using my ARC... Though It's a good upgrade for X10 guys....

Thanks!

nope... Each device requires a different kernel... Don't cross flash kernels...

Same as on windows.... Just use linux binaries
[Xperia Arc Android Development] Flo95:
Nice device you got there.

I'll decide me between Galaxy S III and One X.

That you make kernels for the One X is a big plus for it :D
[Xperia Arc Android Development] DooMLoRD:
:)

we can discuss more on this in some general section thread... send me a p.m. if any such thread comes up where u guys want to discuss these sort of things...
[Xperia Arc Android Development] TheGreatSega:
stock rom

HEY! i just got ported from the X10 forums.. i have an arc s

and i was wondering.. can we use this kernel on SE stock rom..??
[Xperia Arc Android Development] spit85:
Depending on your FW version. I have stock firmware whit kernel v20. But your bootloader must be unlocked.
[Xperia Arc Android Development] X-Droidinary:
+1 I did the same I just don't know how to change the baseband from -64.
[Xperia Arc Android Development] Coolgoly:
Download the baseband you need in .ftf then flash it via flashtool.
[Xperia Arc Android Development] spit85:
And after that you patch it in recovery mode, whit the zip file.
[Xperia Arc Android Development] X-Droidinary:
Do you have a link for the .ftf and zip??

I also tried to do this but it didn't work.
[Xperia Arc Android Development] spit85:
That is not for the baseband, that description. The downloads for the libs and the patches are on this thread. http://xdaforums.com/showthread.php?t=1382657
[Xperia Arc Android Development] X-Droidinary:
You misunderstood me when i asked about the the quote. It was for a background image for bootmanager which i found on DooMLoRD's first post. I followed instuctions but it didn't work.

And thanks for the link for the baseband.

---------- Post added at 12:20 AM ---------- Previous post was at 12:02 AM ----------

The links in that thread aren't any good due to the fact that one of them leads to Megaupload which we all know is now defunct and the others are saying i can't download unless i am the owner of the files.

Are there any other links? Or can you attach the files to a post please?
[Xperia Arc Android Development] spit85:
Scroll a little bit lower on that post, you will see links from other file servers. For me it works
[Xperia Arc Android Development] spit85:
First Flash the basebands whit Flashtool, then boot in recovery and install the libs patch.

Ps, i rarred the basebands in 2 parts.
[Xperia Arc Android Development] X-Droidinary:
Thanks heaps for that.

---------- Post added at 01:37 AM ---------- Previous post was at 01:16 AM ----------

I can't extract the baseband files cos it says they might be an unknown format or damaged.
[Xperia Arc Android Development] spit85:
Try these
[Xperia Arc Android Development] X-Droidinary:
It still says the same thing. if the files need extracting then wouldn't it be easier to just attach the files instead of putting them in .rar folders?

The libs folder is ok cos i can see what's in it but the other 2 just won't open and when i downloaded them to my phone and looked inside with astro there was nothing in there but WinRAR clear shows that there's 1 file in each. It's all jibberish to me.
[Xperia Arc Android Development] spit85:
No, then the file is to big to upload. I will see that I upload it to a fileserver

Im sorry im a noob here. Just finished doing this instruction:

[ how to install my kernel (v14 onwards) ]

download the boot.img & modules update.zip

save the boot.img in the folder with fastboot binaries (fastboot.exe files)

save the modules update.zip to sdcard (on phone)

power down device

start device in fastboot mode

use the following command to flash the boot.img

Code:

fastboot flash boot boot.img

reboot phone and enter recovery

flash the wifi modules update.zip for my kernel

reboot phone and enjoy the kernel

~and its a success! :)

But just want to ask what will i do next? Whats the function of SetCPU, NoFrills CPU Control, IncrediControl, CIFS Manager, Swapper 2 and CallRecorder app from the requirements:

[ requirements ]

stock 4.0.2.A.0.42/.58/.62 FW

bootloader unlocked

working fastboot

u have read this: [How-To] Safely test custom kernels / custom ROMs and get back to stock SE 2.3 ROM

android app for overclocking like SetCPU (paid) or NoFrills CPU Control (free)

NoFrills CPU Control (free) to select I/O scheduler

[OPTIONAL] CIFS Manager (free)

[OPTIONAL] Swapper 2 (free)

FOR Two Way Call Recording: CallRecorder app (PAID) [TRIAL version] {p.s.: keep watching that thread for newer trial versions}

~though ive already installed all of them. And my phone restarts all of a sudden. Why is that so? :(
[Xperia Arc Android Development] spit85:
Don't install two cpu controls at the same time, but just one of those that doomlord advice.
[Xperia Arc Android Development] vifer06:
Anyway what will happen if I overclocked my Arc? Will something bad happen if i dont overclock it?
[Xperia Arc Android Development] spit85:
OVERCLOCKING is speedup your phone, but it is not necessary to do it. You can leave it the default values and just undervolt the CPU, sow your battery life is longer. I have a ARC and overclock it to 1.2Ghz when I gaming, but in normal use I have it to 1Ghz. But I have undervolted to have longer battery life.

I don't know which phone you have. But if you have the ARC, I advice not to go higher then 1.4Ghz, whit gaming or heavy cpu use. How higher you go, how more chance you have to brick your phone. But it is safe when going to 1.4Ghz maximum, when have a ARC, but whit a ARC S, go not to high either.
[Xperia Arc Android Development] vifer06:
OMG. So which one is better? Thats the reason why my Arc suddenly restarts?

---------- Post added at 05:57 AM ---------- Previous post was at 05:55 AM ----------

[

Wow! Thanks for that! Can u pls tell me how to undervolt the CPU?

---------- Post added at 06:01 AM ---------- Previous post was at 05:57 AM ----------

Pls help me how to undervolt the CPU. For longer battery use right?
[Xperia Arc Android Development] spit85:
I use Setxperia to overclock and undervolt. You can find it on Google play. When you open the voltages in setxperia, you will see the normal voltages. Now you can lower down the voltages for each clockspeed, but do it in steps from -25mV, then test if your phone is stable whit that voltages. Normally it can't hurt your phone when it don't get enough mV. Your phone will restart, sow you know the voltage is to low.
[Xperia Arc Android Development] vifer06:
Pls teach me how to do it step by step pls? :(

Then how will I check if my phone is stable?
[Xperia Arc Android Development] spit85:

test kernel DooMKernel v21 released!

test kernel DooMKernel v21 released!!

[ feature/changelog ]

reverted back to my stable 2.6.32.9 kernel source

testing a new patch which will cap the bootup cpu frequencies

if this works, it will hopefully merge the 1.6 & 2.0 kernels so i dont need to maintain multiple version of the same kernel

the device SHOULD boot up at 245Mhz Min and 1Ghz Max (if device is ARC S this will be 1.4Ghz Max)

please test this out, especially those users who have/had issue with 2.0 Ghz kernel booting on their device

blind testing GPU OC

i am posting two version #2021, #3021

both are identical EXCEPT one has GPU OC and the other one doesnt ( i am not telling which one has the OC ;) )

test out both and tell me if u find any difference/improvemnt/notice any lag/issues with respect to GPU (gaming, scrolling menus, etc)

kernel debugging FS is disable for this test kernel i will make it working from next release

this is a test kernel... i want to see if these patches are actually helping out or not... incase there is no real improvement i will revert back the patches...

FINAL VERDICT:

use #3021 kernel!

http://xdaforums.com/showpost.php?p=24755284&postcount=2841

since i have reverted to my older kernel sources u will have to flash the "v15 onwards" modules to get WIFI to work!!!

Thanks for V21

Doing Nenamark2, Quadrant and Antutu tests with each version atm :)

Will report back soon. Doing 3 tests with each benchmark for every kernel version takes some time :D

EDIT:

Tests are done :)

V21 Test 1:

Nenamark2: 13.7fps, 14.3fps, 14.0fps

Quadrant: 1337, 1234, 1313

Antutu: 3750, 3851, 3852

V21 Test 2:

Nenamark2: 14.3fps, 14.5fps, 14.4fps

Quadrant: 1369, 1374, 1400

Antutu: 3754, 3843, 3846

So my guess is, that V21 Test 2 is the version with GPU overclock, isn't it?
[Xperia Arc Android Development] vifer06:
Sorry but just want to ask whats the difference of 2.0Ghz version to 1.6Ghz version?
[Xperia Arc Android Development] mando508:
Test 1 is with GPU OC :-). For me it's always lowering performance so i bet on test1. I tested both kernels for 2h and test 2 is much better in GUI/games, but still some gameloft games sux - f.ex. Backstab does not have objects and geometry pop-in and draw distance & details are too much for arc, so sometimes framerate is really bad (someone know why is that? :D When i'm on stock kernel game has pop-in/out and is working much smoother). Overall gaming performance is great, just some gameloft games having problems, but overall i'm satisfied.
[Xperia Arc Android Development] DooMLoRD:
i request the users, who had problems booting my 2.0Ghz kernels and only 1.6Ghz kernels worked, to please test this new kernel (v21 any one will do)... please check if it boots and let me know as i will soon be stopping 1.6Ghz kernels if the tests are successful...
