[Xperia Arc Android Development] shubu000:
just wondering if any arc s users had used the latest kernel...

is it stable? i'm just gonna be doing it for my mother before i move overseas, i want 100% stability guarantee,

any thoughts?
[Xperia Arc Android Development] vulkanxxv:
Here, in the old country (read Europe) the kernel stability is about at 90%.

But only pumping up the clock
[Xperia Arc Android Development] YouZi:
Thank you, DooMLoRD! Great job! =]

Now I have root and OC :D

But I kinda miss the boring SE TEXT logo, is there an easy way to get it back? If not then just ignore this :p

[Xperia Arc Android Development] Rycon33:
thanks for clarifying, now i understand
[Xperia Arc Android Development] ShyamSasi:
Flashed the new Kernel everything seems to work fine. :D
[Xperia Arc Android Development] SimonZ:
Hi Doom, i've unlocked bootloader (had to happen sooner or later) and now my Arc has your kernel on board! I tried to format successfully the SD in EXT3 but the Arc don't recognize the new partition. Your kernel should have native support for this file system, i'm doing something wrong? Thanks for your work!
[Xperia Arc Android Development] DooMLoRD:
yes native support is there in kernel but u might need to manually mount the partitions
[Xperia Arc Android Development] SimonZ:
mmm.... so whenever i turn on the phone i must to go in memory menu and mounting SD?
[Xperia Arc Android Development] X3R0:
v4: bootloop :(

v3: working
[Xperia Arc Android Development] NiMH_999:
I was just about to mention this problem too. But I thought it was just me.

My problem is that I always use link2sd which automatically put apps in sd but it requires another partition to be created in ext2

This time it tried to use this kernel but link2sd's script could not mount the ext2 partition I had to revert to stock kernel.

Thanks for mentioning that. Hopefully someone will help us to auto mount ext partitions

Regards
[Xperia Arc Android Development] DooMLoRD:
i dont really know much abt link2sd implementation... and i personally havent created any partitions on sdcard...

will need to do some testing...
[Xperia Arc Android Development] NiMH_999:
Cheers DoomLord

Sorry for long talking :)

I should have just put it simply saying: ext partitions are not recognised/mounted (in my phone) by the kernel you posted
[Xperia Arc Android Development] harfot:
After flashing (preserving user data) generic 4.0.A.2.368 followed by DooMKernel v02 the hole lot was working - not very well but working. Problem was I was not able to install neither BusyBox nor APP2SD.

This was followed by 2 more tries flashing but it never worked but I was shure it could work.

So I flashed the original 3.0.A.2.181, used GingerBreak to root and installed BusyBox. It worked.

Then I again flashed generic 4.0.A.2.368 followed by DooMKernel v02. It worked and BusyBox was still working. Then I installed APP2SD and on reboot that part worked also. At last I restored my user apps with Titanium and the were all moved to the new ext3 partion on the SD card.

Later I have flashed the latest two DooMKernels without any problems.
[Xperia Arc Android Development] Evil_Sephiroth:
V04-->all ok.

but

if I set 1.6 1.71.8 ghz Arc have very fast random crash.

If I use 1.5 all work fine.

Is there any app to increase Vcore of processor and achieve e better stability during higher OC?
[Xperia Arc Android Development] SimonZ:
Another request, is possible to add an intermediate frequency between 368Mhz and 768Mhz? The gap is little too. Hey the boot image is very cool!! Good intro with android logo and SE animation !
[Xperia Arc Android Development] SimonZ:
But don't you will fry your Arc? I stay with stock 1Ghz and max @1,2Ghz
[Xperia Arc Android Development] Evil_Sephiroth:
not really

of course my daily is 1.1 1.2

but i want conclude a bench @1.8 like other person with same device.

Probably my CPU sample in ARC is a little not lucky and request higher vVcore to operate at higher frequency.

after bench I use ARC around 1.2 ghz

BTW if Cell fry--->NP death for the OC sake XD (remember me how many PC processor I kill under nitrogen XD
[Xperia Arc Android Development] SimonZ:
But.. but W H Y ?

:confused:
[Xperia Arc Android Development] shubu000:
Thanks for getting back to me. I saw that you have baseband. 36 files. I'd like to stick with. 58 :s

Also for stability sake would it be better to flash 17?
[Xperia Arc Android Development] imranaryan:
hi am new to SE i have unlocked my bootloader can any1 help me in flashing this kernel. am on stock 2.3.4 .42 and is 62 is root able if i install this kernel

please explain and tell me how

will wifi and everything works fine if i install V18-Fiz or do i need to install some moduls i read everything just few confusion
[Xperia Arc Android Development] dinesh690:
Yep, once this kernel is flashed your automatically rooted thanks to Doomlord and you flash via fastboot btw if you didnt know. And flash the wifi modules provided for v15 +

NOT STOCK MODULES :) And yes after modules everything will work :)

[Xperia Arc Android Development] imranaryan:
am going to flash v18-fix do i need to flash that module
[Xperia Arc Android Development] dinesh690:
Yep :) Flash the wifi modules that i provided the link to in the previous post to as it says in the installation guide by Doom :)
[Xperia Arc Android Development] imranaryan:
i flashed v18-fix high but am getting black screen only

will this work on neo v coz i see its written

ARC

-DooMKernel-v18-FIX1-lower_boot
[Xperia Arc Android Development] dinesh690:
No it won't work on Neo, Its specifically for Arc and, as DoomLord has said many times, can damage your device if you flash kernels across different phones.
[Xperia Arc Android Development] imranaryan:
where can i find doomkernel foor neo v
[Xperia Arc Android Development] dinesh690:
Not sure if it exists as hes very busy,but perhaps check the Neo forums.
[Xperia Arc Android Development] Flo95:
There isn't one for Neo V if I'm not mistaken
[Xperia Arc Android Development] GioBlacK92:
Hello! I've at home an icontrolpad very awesome.. but it doesn't work in gamepad mode because if i don't have a missunderstanding the stock kernel haven't the appropriate modules for game controllers and generally HID hardware... cyanogenmod's kernel had this ones, but I love stock UI.. I have only root my device, if I unlock the bootloader and flash this kernel, I will play with the icontrolpad?

PS: I'm Italian.. I'm sorry for my horrible post!
[Xperia Arc Android Development] Duvel999:
Tried v18-fix, but this drains my Battery alot when using wifi & etc.

Back to V18 normal..

V17 wasn't bad, believe V18 is also good..

If I'm not satisfied, Iḿ going Back to 6016..LOL

:cool:
[Xperia Arc Android Development] DooMLoRD:
battery drain will be same on #6016 / v17 (fix1/fix2) / v18 (fix1) the base for all these is #6016...

battery will always drain more when wifi is active...
[Xperia Arc Android Development] LongZheng:
Has CIFS support been removed from this kernel? Cifsmanager isn't working anymore.
[Xperia Arc Android Development] DooMLoRD:
yes... it had to be removed to avoid battery drain...

CIFS was responsible for the increased battery drain...

With v18fix1 I had bigger battery drain in sleep mode. Switched back to v18 without fix1, as it seems to be the best one for me.
[Xperia Arc Android Development] DooMLoRD:

I wish I could get 28% usage in 46 hours, but I use apps like mitalk messenger and a few wigdets and the best i can get is about 20% usage in 10 hours.
[Xperia Arc Android Development] rustynuts34:
Lol I love the battery life on v18 but I still manage to kill my battery every day, except with this I get a little extra :-) think maybe I use my phone too much ;-)
[Xperia Arc Android Development] im_iceman:
Anyone else having problems with occasional bootloop ?

I'm on v17 fix2 - and every now and again (say 2-3 times a week) my phone will just reboot itself and go into a boot loop - I have to rip the battery out to stop it.. I woke up to it happening this morning..
[Xperia Arc Android Development] shubu000:
Sorry guys quick question

So I just get phone to fastboot then flash the .img file? No need to rename?

After flashing the boot I install the module through recovery?
[Xperia Arc Android Development] dp94:
You don't have to rename it, afaik, but it's easier to type only boot.img into a command line. :D

Yes, enter CWM and flash modules.
[Xperia Arc Android Development] irononreverse:
Getting 1 day, 7 hours of life at 15% remaining on .36 baseband. 2 hours better than my previous best, but I'm trying it on .64 baseband now to see if it helps with my phone signal.

[Xperia Arc Android Development] DerEineDa:
I too had exactly this problem with all basebands before -64. Are you using an older baseband? This is a known problem mostly happening with the Neo V, but also with some other devices. I already mentioned it here.
[Xperia Arc Android Development] im_iceman:
using baseband -36 as recommended.. do you recommend changing to a later BB then?
[Xperia Arc Android Development] DooMLoRD:
upto u...

baseband -36 is recommended... if it isnt working well for u then u can use which ever baseband that suits ur region...
[Xperia Arc Android Development] im_iceman:
I'll give -64 a try with Iris's patches and v18-fix.. see how we get on!
[Xperia Arc Android Development] DerEineDa:
Absolutely. Of course it hurts because of a slightly worse battery life, but it's the only way I could fix exactly this issue. Just try it and see for yourself.

For me, ripping out the battery wasn't the only way to fix it temporarely. The device just had to power off. At first I ripped out the battery too, but you can also go into recovery and power off the device from there. This was my way to escape the reboot-loop before using -64.

How to control voltage from init.d？

I use the code that work for X10 but not work for ARC
[Xperia Arc Android Development] DooMLoRD:
hi mate!

when did u get the ARC? glad to see u here :)

i use the same sysfs interface in ARC which i used for X10 so the same commands will work here too...

the freq-voltage table has recently been changed...

regarding voltage setting using init.d scripts...

just make sure ur init.d script is correctly formed... with correct permissions (777)...

[Xperia Arc Android Development] doomed151:
Somehow, with v18-FIX1, it's not as stable as your previous ones (v15 and below). 1.8 GHz always result in a freeze whereas 1.9 GHz works flawlessly with the older ones. Stock voltages, tried both smartassV2 and interactive.

More testing:

v16-test6: 1.8 GHz, interactive - freezes on Quadrant run.

v15: 1.9 GHz, interactive - went through 2 runs without any problems.
[Xperia Arc Android Development] iridaki:
I had some problems with bootloops since V17 and up,

I tried a lot of things and I ended up fixing it but because of the massive trials, now I don't know how! :D

Anyway, I am running V18 (not the Fix 1) because I never use Image Stabilisation in Camera, so I appreciate the extra MB of RAM and my camera works perfectly for my needs.

Quadrant scores are impressive with Smartass V2 and SIO scheduler.

V18: 134Hz-1.6GHz, Quadrant=2390, Linpack=55

Phone is smoother than ever and battery life is comparable to stock kernel.

Not as good, but then again I have tuned my device to achieve performance rather than standby time.

[Xperia Arc Android Development] Kuroyukii:
Since v17 sometimes when I'm on my mobile data and go to facebook my phone crashes and I can't restart it if I don't connect it to the charger.

If I want to start it again the red LED flashes 3 times.

(The battery isn't damaged or empty, cuz I borrowed it as test my buddy and it works well for him, and it mostly happens in the bus to school, it's like 20min after the phone got disconnected from the charger[I let it charge 4-8hours])

I don't know if it has something to do with the baseband 36 which i'm using, but around 8 friends have told me they try calling me and it goes right to the voicemail.

Edit: I switched back to baseband 64 and is the same :( do you know which is the right baseband for Movilnet/Venezuela?

i have added ZRAM & CLEANCACHE to the kernel in v18/v18-FIX1... from my testing atleast this hasnt affected the battery drain... still if u guys want... u can do a comparison between v17-FIX2 & v18-FIX1 specifically with respect to battery draining...

[USB-OTG] NTFS partitions in read/write mode

[ info ]

ok so some of u must have run into this issue that the NTFS driver in the current kernel doesnt support R/W mode correctly...

i was finally able to find a solution to get NTFS drive connected in read/write mode, based on some threads here on XDA...

[ requirements ]

USB-OTG cable

my latest kernel

attached update.zip package

GScript app (free)

LiveWare Manager (it is a default SE app but some ppl/ROMs remove it)

[ how to ]

Following steps are to be done only ONCE (or for the first time to setup everything correctly)

download the attached update.zip and flash via it recovery

reboot the device and start GScript app

now add the connect script:

Menu -> Add Script -> Load File -> select "ntfs-connect.sh" -> save

now add the disconnect script:

Menu -> Add Script -> Load File -> select "ntfs-disconnect.sh" -> save

now close GScript app

attach ur NTFS formated usb device to USB-OTG cable and now connect it to ur ARC/ARC S

u will get a notification saying that "new accessory is connected" (screenshot)

click on that notification and it will start LiveWare Manager (screenshot)

now click on "Assign & Search" and select GScipt app (screenshot)

once this is setup close the app and disconnect the USB-OTG cable with the usb-storage device attached to it

Following steps are to be done everytime the usb-storage device is connected

connect the USB-OTG cable with the usb-storage device attached to it to ur ARC/ARC S

if everything was setup correctly (using above instructions) then GScript app will autostart (screenshot)

wait for a few seconds and then select "ntfs-connect", this will start execution of the script, if u havent used GScript before u might get a "Superuser Prompt" asking you for permissions, select yes/ok/allow... this will give u some output (screenshot) which basically will tell u that the usb storage device has been mounted to /sdcard/usbStorage

now just use any of ur favorite file manager apps and access that usb-storage device in read/write mode at the /sdcard/usbStorage folder (u dont need to create that folder urself the script will make the required folder) (screenshot)

to disconnect device properly

launch GScript app and select "ntfs-disconnect", this will execute the script and give u some output (screenshot)

now just verify that the device is no longer mounted at /sdcard/usbStorage folder

finally disconnect the USB-OTG cable
