An question for DooMLord and maybe somebody else if know the answer...:) I really enjoy using your Kernel and as I can see thats the only way to have Recovery permanently in ARC...:) But I was wondering something...:) Is it possible to change the SplashScreen after flashing your Kernel? I did that on my old device (HTC Desire) and I would like to put my favourite picture in SplashScreen...:) How can I do that?

Thanks in advance for all your help...:)
[Xperia Arc Android Development] DooMLoRD:
Search one of my thread explains how to create ur own splash screen...
[Xperia Arc Android Development] Ninolina:
Thank you...:) I will try to find it...:)

So, just to be absolutely sure:

I am using this kernel on my Arc S. Looking at No-frills I can see that the max frequency is set to "1,024 GHz". So my CPU seems to be underclocked using this kernel, until I change this setting, right? If I change this to 1,402 GHz, this would NOT overclock my CPU, because this is the frequency the MSM8255T is intended to use. Is this correct?

I don't want to overclock my device at all, but I have to use this kernel for arconium-rom.
[Xperia Arc Android Development] harfot:
Right, your default speed is 1,402 GHz so at that speed it's not overclocked.
[Xperia Arc Android Development] jumptailo:
+1 on this!! :)
[Xperia Arc Android Development] DooMLoRD:
actually even on stock 1.4ghz speeds ARC S pulls more current... so if 1ghz is working fine for u i highly recommend running it at 1Ghz instead of 1.4ghz if u want better battery life...

current @ 1.0Ghz -> 1200mV

current @ 1.4Ghz -> 1250mV

ref: https://github.com/DooMLoRD/Xperia-...ernel/arch/arm/mach-msm/acpuclock-7x30.c#L124

u can even try undervolting!! :)

btw: FXP has tested undervolting of 1000mV to be stable to 1.0Ghz:

https://github.com/freexperia/semc-...aster/arch/arm/mach-msm/acpuclock-7x30.c#L133
[Xperia Arc Android Development] cezarL:
Yeah, but let's not forget a small thing called 'sample variation' :)

Some devices will allow more undevolting, others won't.. it's a matter of luck.

Here's the voltage table of my Arc S (running CM7, Doom Kernel v3, o/c to 1.8GHz), hope someone might find it useful as a reference.

I suppose I could have went a little lower here or there, but I didn't feel like testing each frequency for stability :)

Hm... I've got a problem.

SDK is installed, fastboot is working.

But I have a "Waiting for Device" when I type fastboot flash boot boot.img

Can someone help me please?
[Xperia Arc Android Development] harfot:
...and you turn off device, holding menu button while inserting cable and wait for blue led to light before releasing menu button?
[Xperia Arc Android Development] DooMLoRD:
hi FormelLMS,

i hope u planning to port ur epic MiUI to this device ;)

ok so firstly u need to confirm that u have unlocked the bootloader... once thats done just reboot into fastboot mode (adb reboot bootloader)... a BLUE LED should light up... once u see it then execute (fastboot devices) to check if device is detected... if device is detected then execute the command to flash kernel...

cheers!
[Xperia Arc Android Development] FormelLMS:
Hey, thanks for your answer. On another computer everything works. I don't know, what happens on the first one. :-D

I really don't know if I can do my miui rom for this device.

You know this here is a bit another.

On all other devices its easy to flash a cwm recovery and apply kernel and rom zips as usual.

Here I have to read and investigate many things :-P

And, here are already 6 different miui roms. I don't know if we need another one. :-\

[Xperia Arc Android Development] DooMLoRD:
most of them are based on Jason's ROM...

it would be great to see ur work for this device...

only issue on new Xperia 2011 devices is that (currently) u cant flash kernels via recovery... but atleast fastboot is an option...

btw CWM recovery is already in kernel ramdisk (in boot.img)... no separate partition for recovery..

can i use doom kernel on my arc ..4.0.2.a.0.58 baseband8x55a-aaabqoaz-203028d-58 if so ,where can i find it and how many thanks
[Xperia Arc Android Development] DooMLoRD:
same as the links in 1st post
[Xperia Arc Android Development] irononreverse:
Over the last few days, I've been getting around 22+ hours out of my Arc on .42 and v15 Doomkernel.

Could not be happier!

Apart from leaving overnight for about 7 hours whilst sleeping, I check my phone pretty much every half hour, use mitalk, sms and facebook, on wifi and 3G.

Screen is on around 35-50% of the time.
[Xperia Arc Android Development] iAchilles:
hi dudes and dear doom ...

i was using this kernel in perivous old version and that time i hade a huge battery drain ... but and now i back :)

what's going on v15 ??? what are big movemant(features) in v15 than old versions ??

i want to know, have this version problem like old versions like battery drain OR SOMETING NEW Prob. ?????

and i see in 1st post that this kernel will wipe all SD card data ???? yeh ?? is it true for v15 ??? it is horible for me to backup my sd card because i have huge size of data in my SDcard .... SO any Solution ???

thx a lot if u can give me ur exprience and ur info
[Xperia Arc Android Development] terenchan:
This kernel will not erase your SD.

What is mentioned in OP is there is an option for partition your SD, and this option will erase all the things in your SD LOL.
[Xperia Arc Android Development] Flo95:
Had it tonight again and it just layed on the table which made me waking up at 5 o'clock in the morning.

Was a real bootloop today I guess.

Even if it's stable for 2-3 days now and was for ages stable (4 months or so) I added 25mV back to the first 3 frequencies that I had @ 800mV. Hope that fixes it, even if I think that's not the cause as it works stable for 2-3 nights while charging @ 800mV.

Maybe I have to reflash it :(

[Xperia Arc Android Development] jguimaraes1:
Can someone help me? My Arc S with DoomKernel starts rebooting from nowhere.

Yesterday happened twice, and today it happened while sleeping so my clock alarm didn't work...

Did anyone had the same problem?

Thanks in advanced!
[Xperia Arc Android Development] harfot:
Have not tried it in that way but try to wipe cashe.
[Xperia Arc Android Development] jguimaraes1:
Can you tell me how do I wipe the cache? I went with Astro to /cache folder and it was empty...
[Xperia Arc Android Development] iridaki:
May I suggest something that will not solve the reboot issue, but will ensure that you will avoid problems such as missing your alarm/reminders etc?

Remove PIN protection.

I've owned smartphones since '04 and I've been modding them heavily and came to realise that PIN will only cause problems. Without it, a reboot would just last a few minutes and then your phone will be back up and running. With it, if you don't happen to see the reboot happening, you'll be stuck at PIN screen and the phone will be useless.

If you are worried about privacy, set a lock pattern or a code.

And if you don't want to input it every time you unlock, there's a nice app I use called "Unlock with WiFi" that skips protection every time you are connected to any WiFi network you have chosen (eg: your home).

I know it's not a solution per se, but take it as an advice from someone who has been late for work one too many times! :D ;)
[Xperia Arc Android Development] jguimaraes1:
Now that you talk about it iridaki, I've disabled the pin security code. That's true what you said. If I lose the phone I prefer that they use the sim card so I can remote it and disable it. ehehe

Cheers!
[Xperia Arc Android Development] Flo95:
Reflashed it on Saturday (without wiping data) and today I had it again in school :(

What could be the cause?

Never had that bug 4 months long so undervolting or overclocking shouldn't be the reason and I just oc to safe 1.4GHz and uv -100mV

I don't know what to do and that bug or whatsoever really sucks and I really want to keep that device as there's nothing out I'd like to change it for (best phone imo)

It happens always after 50-65 hours when it charges or even lies around - uninstalled Lookout as I don't see a need for it and it acted up by preventing the device from going to Deep Sleep, but I think that wasn't the cause.

EDIT:

Found out something good, my CPU is mot broken, as the Arc freezes and restarts normal if CPU related, oc'ed to 2GHz for showing off and it was too long, so it froze and restarted then, but no bootlooping.

But still, what's the cause? Can't find it
[Xperia Arc Android Development] silveraero:

Arc S, L18i -

After Unlocking the Bootloader and Flashing this Kernel, (I dont know which caused it) I lost USB connectivity to my PC. Relocking, Flashing Stock Didnt help.

This is What I did - http://xdaforums.com/showpost.php?p=20396934&postcount=8

Doom, Is there a way for us, L18i Users to get this kernel, without losing USB ?

Because, While this kernel worked, It totally rocked !
[Xperia Arc Android Development] DooMLoRD:
strange shouldnt happen at all...

the kernel works w/o any issues on numerous LT18 (ARC S)
[Xperia Arc Android Development] JazonX:
Re-did the Whole Process., Now Its Stable.

Arc S - LT18i has a 1.4 GHz Processor, After Flashing DoomKernel, It now shows as the Default is 1.0Ghz,

So If I set it to 1.4 Ghz using no frills, Is it still considered as Overclocking ?

Does still carry the risks such as overheating and Other overclock related issues ?
[Xperia Arc Android Development] DerEineDa:
I had this question as well. Please look at the answers here and here.

But to be honest, I would prefer a special kernel by DooMLoRD for our LT18i. I don't know if DooMLoRD uses the same voltages for 1.4 GHz in his kernel as Sony Ericsson uses for their stock-kernel.
[Xperia Arc Android Development] DooMLoRD:
there is no need for special kernel...

kernel IS EXACTLY THE SAME

for voltages check the posts which u have quoted
[Xperia Arc Android Development] DerEineDa:
I know that the kernel is the same, as there is just one download of the source-code for several devices. But what I don't understand then: Why does the Arc S run at 1.4 GHz and the Arc at 1.0 GHz? Is this defined at compile-time?
[Xperia Arc Android Development] harfot:
They have different CPU's,

Arc: 32bit Qualcomm Snapdragon MSM8255 (standard 1 GHz)

Arc S: 32bit Qualcomm Snapdragon MSM8255T (this one is dual core standard 1.4 GHz)
[Xperia Arc Android Development] uit.edu:
Any One help me fix the Link to download MODULES for DooMKernel (v15). Link is error.
[Xperia Arc Android Development] DerEineDa:
Of course, but this can't be the reason, because the MSM8255T runs at 1.0 GHz, too, when using DooMKernel (and not changing the frequency manually).
[Xperia Arc Android Development] iridaki:
Because for the sake of safe-booting Doom has capped the frequency to 1GHz (as this is default for the Arc).

By the way, Arc S bears the same chipset as the Arc, only tested in higher frequencies.

You can change max frequency with lots of Market apps or even a simple init.d script.

I hope this clears it out for you.
[Xperia Arc Android Development] JazonX:
I will stand down on the Kernel thing for now. I prefer not to play with Processor Clock frequencies, Except heat they havent generated much in the past for me.

All I wanted was the USB OTG and Two way Call recording, so for now I will go back to the stock kernel.

Your kernel was quite awesome., It was faster than the stock kernel.
[Xperia Arc Android Development] DooMLoRD:
The defconfigs for ARC & ARC S are the same (semc_anzu_defconfig & semc_ayame_defconfig)

So the kernel compiled (zImage) is EXACTLY the same..

The change happens at runtine.. depending on cpu stepping (8255/8255T) the max clock is either set ti 1.0 or 1.4Ghz...

do this simple test... get the kernel.sin from ARC S firmware... flash it on to ARC... ur max CPU clock will still be 1.0Ghz... now flash the same on ARC S... the max CPU clock will now be 1.4Ghz :)

yes thats cause 1Ghz is max on ARC and if used on ARC S then u are actually undervolting/underclocking (might give better battery life)

your wish mate... i have done my best to keep the CPU frequencies in check so that u do not need to worry abt CPU clocks... if u dont change anything CPU (clocks) will function as stock :)
[Xperia Arc Android Development] aimcr7:
Can i use this kernel on NEO?

Cause i think so much similarities (in hardware) between neo and arc.

@doom I love your kernel since i am on X10, and now i switch to neo and so sad when i know that you stop developping kernel for neo.
[Xperia Arc Android Development] DooMLoRD:
hi mate,

yes ARC & NEO have very similar hardware (even camera sensor is same)...

i dont have NEO with me to test...

do one thing, may be u can help with testing...

instead of flashing the kernel, hotboot it:

fastboot boot boot.img

and just check if device boots...

if it does check the usual things (camera, etc...) [wifi/bt wont work unless u flash correct wifi modules]
[Xperia Arc Android Development] robobear:
I have but 1 reques only... Please include app2sd since arc memory is slow and i dont understand other methods of enabling app 2 sd
[Xperia Arc Android Development] aimcr7:
Okay mate, i'll test it for you.

But i want to know, if it possible to relock the bootloader after unlock it?

I just too worries if i flash wrong kernel it will brick my device, since i just bought it one month ago. :(

Someone in NEO section said that he flashed firmware .58 for arc and it works great except accelerometer censor, and the solution is just replace it with module from neo .42. And all works.
[Xperia Arc Android Development] DooMLoRD:
yes u can relock bootloader ;)

check thread by Blagus/FXP

actually thats the reason i told u to hotboot the kernel (to avoid damaging the device)

interesting so the accelerometer sensor is different...

em if i get time i will post easy init.d script...
[Xperia Arc Android Development] aimcr7:
Okay, i'll test it later if i am on PC.

Okay. I'll try and report it to you.

Yes i think.

But i hear we lost drm code if we unlock our bootloader and we cant recover our drm code, is that true?

Sorry for noob question.

I am new on 2011 device. :)

Even flashing kernel, i havent try it.
[Xperia Arc Android Development] DooMLoRD:
yes drm is lost...

its ur wish if u want to unlock bootloader
[Xperia Arc Android Development] aimcr7:
DRM is only useful for update service and TrackID, isnt it?
[Xperia Arc Android Development] DooMLoRD:
TrackID now has a drm free version...
[Xperia Arc Android Development] aimcr7:
Yes, so it just for update software right?

I am on my way to unlock my bootloader.

And we always can update our software from wotan server and flashing via flashtool. Oh i miss my moment with x10i. :'(
[Xperia Arc Android Development] Flo95:
Sorry, but the Arc S has a single core, too
[Xperia Arc Android Development] cphil19:
Doom-

Sorry to bother you. I just tried flashing your custom kernel on my Xperia Acro (the Japanese version of the Arc), and while successful, I lose all service when doing so. Everything is listed as unavailable or unknown.

I wonder, is this because au KDDI uses a CDMA frequency? Anyway......any suggestions you have would be really appreciated. Thanks
[Xperia Arc Android Development] harfot:
No need to be sorry - you are right and I am sorry.
[Xperia Arc Android Development] cphil19:
Hey guys. My Acro phone is currently unusable as the custom kernel wiped out my service (probably due to the CDMA frequency KDDI uses out here in Japan).

This is pretty imperative as I have no access to a phone at the moment and really need to figure out how to get it working or at least get the stock kernel back.....

Thanks
[Xperia Arc Android Development] DooMLoRD:
i have explicitly mentioned that this works on ARC & ARC S ONLY!

ACRO will need a different kernel...

find a FTF for ur device or try WOTAN server

hi all.this is my pics from my arc...and the question is, if i install this kernel i have more battery usage etc???
[Xperia Arc Android Development] rkanwar:
How is v15 working out...after installing modules does everything work?
[Xperia Arc Android Development] iridaki:
Yes, battery usage is increased comparing to stock kernel.

To give you an idea, while the phone is idle on stock kernel

(Data ON, Sync ON, Background data ON) I lose 1-2%.

With V15 I lose as much as 5%.

While actually using the phone, the difference is not that great between the two.

It's ultimately your choice, but my advice is don't worry too much about battery life. :)

Any plan to compile your Kernel with latest source? (4.0.2.A.0.61_62.tar.bz2)
[Xperia Arc Android Development] DooMLoRD:
i saw them long time back but those sources are useless for ARC...

they just add new device defconfigs and related files:

SEMC Strawberry

and

SEMC Azami
[Xperia Arc Android Development] DerEineDa:
Are you absolutely sure about that? SE said this new firmware fixes the random reboots on some devices (like Neo V, but I also experience this with my Arc S). They said it has something to do with memory management, which I believed to be some kernel-thing.

Well, I will just believe you in this. I will just continue to use your kernel and update the baseband and system. If reboots still occur, I will just try the stock kernel and see if it helps then.
[Xperia Arc Android Development] DooMLoRD:
u r most welcome to download the sources and compare them urself :)
