[Xperia Arc Android Development] DooMLoRD:
refer to the 1st post for correct links of latest kernel/wifi modules...

well on the newest kernel versions i am using a different CPUFREQ driver...

the older one was causing increased battery drain...

so either we can have older, higher battery drainer kernel OR we can have the latest one which doesnt drain battery that much...

1.4/1.6 Ghz is ideal overclock for ARC (LT15)... anything higher used for long time/prolonged use is bound to cause permanent damage to the chipset...

anyways when i get time i will try modifying the existing driver more, may be it can improve stability at high frequencies...
[Xperia Arc Android Development] ChefChaudart:
Multiple recoveries

Forget ....
[Xperia Arc Android Development] DooMLoRD:
ERRRR.... thanks for the correction!!!

it was a copy-paste fail! :p

had copied most stuff from the X10 BootManager thread....

anyways now i fixed the post :)
[Xperia Arc Android Development] Crocodile1973:
Any chance for the old cwm by you with big touch buttons, even if it's just the file so we can boot into it?

also by default via xcharge, mine goes into what ever the last recovery i used, it doesn't default to your one.
[Xperia Arc Android Development] Ritmasz:
I can't flash this kernel, I keep getting:

FAILED (status read failed (Too many links))

finished. total time: 1.240s
[Xperia Arc Android Development] kryddan:
Just an idea, but maybe you could make two versions of the kernel, one with the more cpu-stable driver and one with the more battery-efficent driver :) ?
[Xperia Arc Android Development] DooMLoRD:
NO.... dont have the time to do that...
[Xperia Arc Android Development] finbaar:
Just thought I would report my experience. Running Xperia Mod v6.0 with Doom kernel 18 rev 1 and the -36 bb and libs. My phone was unplugged at 23:00 last night and I checked it at 06:00 this morning. Battery was 95%. So a 5% drop in 7 hours with wifi on (never sleep) and full sync. Great work and I will donate again tonight when I get home.

I think that for me I will now keep this set up until a fully functioning custom ICS ROM is available. I have tried CM7, SE Tweaked and Arcomium as well as Xperia Mod. I have used Blend Kernel and several Doom Kernels as well and for me release 18 is best. All have been good and shown improvement over the last few months. I am very happy with my Arc now, much happier than when on stock. My Arc is stable with OC to 1600 MHz and undervolt -50 mv.
[Xperia Arc Android Development] emanuele95:
what doomkernel do i install on my arc with ics cm9??
[Xperia Arc Android Development] dp94:
No one, use FXP's kernel for CM9. ;)

Hi Guys, after loading V19 is der a need to reload the Baseband and wifi modules?
[Xperia Arc Android Development] mo786wp:
Awsome, just flashed it, loving the full touch recovery. Awsome stuff.

"Doom Kernel", definitly as awsome as the name sounds :-)

Hey guys,

tell me, what is the difference between the 1.6 and 2.0 Ghz version? I'm confused :confused:

Dude even though you don't develop for us directly (neo user) but your sources are extremely useful and often helps devs of other devices greatly, so thanks for all the hard work man
[Xperia Arc Android Development] SimonZ:
For me crash when install timescape v5 for Arconium 7.1, now i come back to v18 fix1 without full touch recovery and timescape install correctly. Doom check the issue and thank you for your big work!

One question again: v19 introduces GPU oc but will this decrease battery (and

gpu) life?
[Xperia Arc Android Development] FelipeRRM:
Guys, when using NoFrills , what is this I/O scheduler thing?

And what's the best governor in your opinion, for good battery and perfomance?

Thanks!

agree,cause i cant feel the different when changing from one IO to another;)

from my ARC
[Xperia Arc Android Development] DooMLoRD:
the touch recovery is still in development and crashes sometimes... thats why "soft reboot" feature is included... also bootmanager is there so u can use older recovery if the new touch recovery is too buggy for u...

we dont know... only testing can tell for sure...

thanks... but its not just for NEO, my sources gets used/ripped for almost all Xperia 2011 devices :p
[Xperia Arc Android Development] johnbarleycorn:
Hello, I have freeze problems with the new V19 with the governors smartass, savagedZen and like, while everything seems to go ok with performance, ondemand and conservative ... this looks especially at frequencies of overclocking (> 1400 MHz). This creates problems because what I normally use smartass V2, is solvable?
[Xperia Arc Android Development] DooMLoRD:
kindly enlist all governors and all frequencies anyone is having problems with...

(frequencies above 1.6GHz should not be considered)
[Xperia Arc Android Development] johnbarleycorn:
Ok, I need some time to test them all, do the test at 1600?
[Xperia Arc Android Development] johnbarleycorn:
Ok, installed the new SE tweaked V1 and restored the default voltages of kernel V19

I have not seen freezes at 1.6GHz, making a test quadrant with all governors.

Probably the instability that I was due to Undervolt and a different needs of governors in relation to various voltages (i suppose that smartassv2 and savagedzen require more higher voltages or using frequencies not used by conservative / ondemand)

......or is there a bug in the previous rom that goes in conflict with the kernel.

Now i testing undervolt at 1600 with smartass V2

Tanks ;)
[Xperia Arc Android Development] mo786wp:
Howzit guys, another quick question with regards to Kernel and the full touch recovery.I flashed the V19 Doom kernel on my phone abut cant seen to figure out how to acces the full touch recovery thou?

I tried using the back button, the menu buttom and even volup and down button but keep getting to the CWM-Based recovery v5.0.2.7-nAa-r2, funny thing is that yesterday i got to the full touch revoery menu but today im getting to this menu even if i keep tapping the button after i try tapping the button after i see the blue light.

Any idea? what am i doing wrong now again :-)
[Xperia Arc Android Development] DooMLoRD:
if u are on my kernel u do not need the locked bootloader recovery... uninstall/remove it...
[Xperia Arc Android Development] johnbarleycorn:
Hello DOOM, I made another test by assuming that the cause of the freezes were Undervolt .... Well it is so, the following happens:

- TEST 1 - Voltages default:

no problem at all frequencies and all the governors!

- TEST-2 - 100 mA Undervolt freq. 134400 to 1516800 (included); standard volts freq 1612800 to 2016000 - governor SmartassV2:

all right up to 1500MHz, when I set the frequency to 1600MHz .... CRASH ..... but this is as the standard voltage and lower frequencies until recently worked fine

Another strange thing, when I use the governor "performance", each single frequency allows very massive undervolts (on the order of 150-200 mV) with no crash, when i change governor with smartass V2 and choose a frequency of 1500 or higher ..... CRASH! ...

I hope I was clear, my English is a real crap and I'm leaning to google translator
[Xperia Arc Android Development] DooMLoRD:
the reason for the crashes during undervolting and governor change is that there is an issue of crashes when there is a jump in the voltages...
[Xperia Arc Android Development] bmwbasti:
Hi Doom,

first of all: Many many thanks for your time and energy you spend for our phones :)

Doomkernel is still the kernel of my choice and i think this won't change until i get a Xperia S quiet accidentally (oh god, i love this piece of technique only form looking at pictures :eek:) :D

No two questions regarding recovery:

Can it be that it's not possible to choose a .zip (not called update.zip) to be flashed within the noe touch recovery? I didn't get them displayed :(

A question about cwm in general: If i make a backup with cwm and afterwards i totally reset the phone (exept the backup on sd card) and i flash the kernel afterwards again, can i restore the complete phone again?

So does a cmw backup really save all data (Apps, settings, etc.) or only system data?

Kind regards

Basti
[Xperia Arc Android Development] Finalfour:
I can't understand, where full touch recovery? I flashed you kernel, and may touch has gone! Noe i see only blue meniu and i can move only with volume up/down buttons. With you previous versions all was ok...
[Xperia Arc Android Development] harfot:
Try details of boot manager from this entry.
[Xperia Arc Android Development] DooMLoRD:
just select the ZIP file... full name will be displayed in title...

CWM backups save the complete system, data state... so when u restore all ur files are restored...
[Xperia Arc Android Development] bmwbasti:
Hi Doom,

thanks for your answer.

I can't select the zip because it doesn't show up in touch recovery. I copy the zip to the root of the so and when I navigate to the s in recovery only the folders are displayed but no files.

Kind regards

Basti

EDIT: Oh dear, i just recognized that i can scroll in the recovery sidewards, sorry :(

Are the backups compatible made by one of the cwm versions compatible to the other versions?

Can a bakcup made e.g. with your custom cwm be restored with the touch one?
[Xperia Arc Android Development] DooMLoRD:
yes backups are compatible with older CWM :)
[Xperia Arc Android Development] hootnath:
so what are the benefits and drawbacks of using the doom kernel over the stock kernel? my priorities are battery life, multi tasking, smoothness and 3g performance.
[Xperia Arc Android Development] hootnath:
how do I install this anyway. I am on stock kernel n .58 ROM with locked bootloader. I guess I know how to get it unlocked, but how do I know if I have a working fastboot n even then how do I install this? can I use the recovery available for stock ROM with the locked bootloader? otherwise how else.
[Xperia Arc Android Development] Jinx13:
To check if fastboot is working go to service menu *#*#service#*#*

Then service info

Then config and if it says "Bootloader unlock allowed: Yes"

Then you have fastboot.

Or turn off phone hold menu button and connect cable see if you have a blue light

[Xperia Arc Android Development] swavab:
Hi dear doom,me changed to xperia pro mk16,and really missing enthusiastic arcy goodies..and as a request-any chance of one kernel for this device in future,,it wil b very helpful because there is no special forum for the same in xda..thats y requesting here-sorry for that..
[Xperia Arc Android Development] DooMLoRD:
I only develop for the devices which I have and the ones that I am personally interested in...

If any device community is interested in donating a device for development then I might develop/support that one too...

Xperia Play users donated a device to me and I am actively involved in development for that device (kernel, recoveries)... I also got a Samsung Galaxy SL from users of that community and I have created an awesome kernel for them which has sparked/inspired new kernel developers, currently my teammate , Napstar from my team Team UtterChaos, has that device and he is working on kernel & recovery...

As of now I am saving money for the Xperia S or ION and HTC Edge or One X...
[Xperia Arc Android Development] ChefChaudart:
Great

Good news :) I may replace my HD2 with a One X an my Xperia with a Xperia S :D
[Xperia Arc Android Development] ronyscomparim:

[Xperia Arc Android Development] Flo95:
My Arc restarts every 2-3 days @1.4GHz with low use and often with heavy use.

Any chance to have a kernel version with the old freq table?

Mine seems to hate the newer frequencies :(

Really hope you could do that, testing stability with 1209MHz now.
[Xperia Arc Android Development] DooMLoRD:
Why dont you provide exact error details?

Upload the /cache/recovery/recovery.log file

Seems u r the only one reporting this...
[Xperia Arc Android Development] Crocodile1973:
Doom can we have that nice silver/grey android man in CWM during a backup or recovery, the ics one is great and has the big buttons back.
[Xperia Arc Android Development] h.debnath:
thanks i installed the latest kernal v19 with BB -36 for the first time on my rooted stock .62 arc, but now it says i have no root access even though i have superuser.

titanium backup, busybox, script manager does not work anymore, is there any solution?

Edit: found the solution by applying superuser fix, thanks!
[Xperia Arc Android Development] Flo95:
Didn't more users report worse stability compared to older freq table?
[Xperia Arc Android Development] DooMLoRD:
The issues of other users are for stability at very high frequencies 1.7/1.8/1.9/2.0 GHz...

Ur issue is different "Reboots after two days"
[Xperia Arc Android Development] Flo95:
Oh, okay

Also happens after maybe an hour after reboot with heavy use.

Testing @ 1.2GHz now.

If it happens again I might try a new ROM, when it isn't the kernel
[Xperia Arc Android Development] harfot:
I had some strange issues with unstable performance, data transmitting working on internet but not able to syncronize mail. Neither could I flash another ROM or kernel without bootloop.

I thought it might be in cause of flashing too manu different units, så I decided to flash a .62 stock ROM, rebooted and installed it for use.

Then again flashed newest DooMKernel v19, rebooted and now everything is working OK again.

Btw I always use it @1.4GHZ.
[Xperia Arc Android Development] EvilEdenX:
i do apologise in advance but i cannot find the download to the kernel...? can someone upload the zip for me please. many thanks
[Xperia Arc Android Development] harfot:
It is in post #1 @ the text <NEW>
[Xperia Arc Android Development] Flo95:
Found something bad about your modded touch recovery, well not really-

I backed up my ROM to try ICS, then I wanted to turn on USB mass storage and while navigating my phone slipped out of my hand, I catched it and touched the screen somehow with my hand and did a factory reset :D

Thanks god I made a backup 2 mins before that happened :cool:
[Xperia Arc Android Development] rafu997:
Just a quick question. I read that we don't suppose to use usb stick for longer than 10 min (USB OTG). Is that true? And if it is how about other devices? Like keyboard or Xbox360 wireless reciver?

Don't know if it is right section and topic but I refer to "[USB-OTG] NTFS partitions in read/write mode" by DooM:)
[Xperia Arc Android Development] Flo95:
Came back from ICS and installed V15.

And suddenly it runs @ 1.6GHz. My Arc is strange

Freeses @ 1.6GHz on V19 after 0.5 seconds and on V15 it runs. Will test further.

EDIT:

Back to V19 and now it runs @ 1.6GHz.

Strange. And sorry for my complaint.

EDIT 2:

1.6 @ stock voltage, rest undervolted again and 1.6 crashes after 5-10 seconds and not instantly.

1.4 seems good :)

Also it ran hotter @ 1.6 than on 1.4 and I don't want to kill it ^^
[Xperia Arc Android Development] DooMLoRD:
i need some testers...

those of you whose devices dont boot/get stuck at bootlogo using the 2.0 Ghz kernel and then only the 1.6GHz kernel works for u, kindly reply to/quote this post so that i know whom to send the test kernel....

What am I doing wrong? I flashed the kernel(using the guide obv), but now it is just stuck in the bootlogo, and it won't boot, and I cannot enter the recovery!(what is the button to enter recovery? Vol-?)
[Xperia Arc Android Development] redstorml:
back bbbbbb
[Xperia Arc Android Development] DooMLoRD:
Kindly give complete details...

Which Rom u on? Which fw? Which kernel did you flash, file name?

How did u flash kernel?
[Xperia Arc Android Development] ArmorD:
Arconium 7.2, 402A30.58, I flashed the latest kernel, seems to be v19, ARC-DooMKernel-v19-BM-v2-high-boot. I was just wondering do I need to install the recovery manually, but after reading the article with time, it is pre-installed.

I'll give it a try again, with fresh-downloaded files.

EDIT! Oh yeah! It does work! The files I downloaded were corrupt(odd, I tried to download it two times :confused: ), but I downloaded 'em again(3rd try), and it's working! Great, love it.

I build your kernel and do follow test：

memory increase only

GPU OC only

Both two

and memory increase is good in some game

But GPU OC make the 3D more performance lower the before
[Xperia Arc Android Development] DooMLoRD:
thanks for testing...

as i said before if i get reports that GPU OC is having a -ve effect i will remove it! but its not then i will keep it in future kernels...

[Xperia Arc Android Development] DooMLoRD:
so guys just wanted to let u all know that i will soon be upgrading to the Xperia S (in a few weeks time)... unfortunately i will be selling my ARC as i cannot afford to outright buy the Xperia S, its expected to cost 650$-700$ (USD) here in India... hopefully i will be atleast able to raise around 350-400$ by selling the ARC...

i will continue to develop and support the Xperia PLAY as the PLAY user community had donated that device (a few months back)...

so i will be stopping all development for this device once i sell it...

if the users of this community (ARC/ARC S) are willing and interested in donating some money so that i may be able to keep the ARC, do let me/other know... BUT this has to be community's decision... u guys are already well aware what i am capable of [development wise ;) ] and i am sure u will appreciate the level of support i provide for my projects; so if u guys are interested do let me know so that we can openly work this out, may be start a donation thread/etc... also if most of the community is not interested its fine, we had a great run and i am sure many users benefited from the developments which i have made for this device...

PLEASE DO NOT THINK THAT THIS AS A SCHEME TO EXTORT MONEY...

most of u have known me since the Xperia X10 days so u know what kind of a person i am... but try and understand i want to buy the shiny new devices :D and i wont be able to afford them unless i can sell some of my older devices... BTW i am also selling my HTC Flyer... so if anyone, who is in Pune/Mumbai, Maharashtra, India; is interested in buying these second hand devices (Xperia ARC, HTC Flyer) from me do let me know via p.m., price is negotiable...

P.S.: i dont get devices from SE/Sony to develop :p

so no further interest from u guys about this? :

anyways i am working on a new version of the kernel which has tons of upstream patches, i dont really know if those are helping out (performance/stability wise) but i think its worth testing out... and since there is low user interest for the above that will most probably be the FINAL version of my kernel for ARC/ARC S...

3) Baseband version: 56

4) kernel version: doomlord 19

5) build number 4.0.2.A.0.62

Kindly help, pls..............

Thank for your reply. Actually I try to flash the new ics rom recently, but after factory reset become like this.

And, while I want to use fastboot to flash chaos's Rom mooded Rom v5.5, the screen show "xxxxxx partition too small, failed" something like that. Even I flash back the .62 also something.

Could you recommend any link for solve this problem? Thats will be great.

Thanks!
