currently using updated version of this kernel and i must say its a killer one..

smooth with my current rom Jellysandwich 8.5..

i will still continue monitoring the performance..

keep up the great work..:D:good:

I can't beleive there's so much people, who still ask where the wifi modules for the Vengeance kernel to me / someone else, but they're already have the kernel.

So, I post this :

[Xperia Arc Android Development] :
yes you can
[Xperia Arc Android Development] rusher01:
does this kernel recommend any baseband or it just concern ROM?:confused:
[Xperia Arc Android Development] sony xperia fan:
Sorry, if my question is stupid.

Where is the kernel in the download link?

There are lot of files and I do not know which one to download, I downloaded some of them but I see a file with .elf extension.
[Xperia Arc Android Development] vashta:
Nah.. ur not stupid, just got seriously eye problem :D.

Check again Post 2 .

Wich part of Arc = Anzu, Arc S = Ayame , etc you don't understand ? :)

There are 3 kernel file i know.. *.img / *.elf / *.sin . Just instal like you usually do, using flashtool, etc.
[Xperia Arc Android Development] thelast3lack:
thanks for kernel,

but where is modules? i cant find it ...

OMG, are you can read people ??
[Xperia Arc Android Development] fireillusion:
Re: [KERNEL][ICS] Vengeance [ARC/S/PRO][1.32][18/02/13]

I want to ask something even if it its stupid:

I have an arc. If I flash original ftf for arc s for more memory which kernel should I flash? For anzu or ayame?

Thanks on advance
[Xperia Arc Android Development] vashta:
Actually, this kinda new one i read about this type question :D

Better keep flash it with Anzu mate.

I never have problems with that, idk what trouble you may encounter if using ayame, as i never try that.

Edit : Curious about that, i try to flash with ayame. And the result is my phone kinda heat. And the default proc speed is 1,4 ghz.

So basically, ur arc device, will be automatically overclocked not by your own will.
[Xperia Arc Android Development] murerlars:
This worked for me, thank you.

And thanks to Rachit Rawat for a super kernel... :)
[Xperia Arc Android Development] bobgeneric:
For best stability, use same baseband both ROM and kernel.

The UHD 3.0.1 ROM is working smooth and flawless with Vengeance kernel.
[Xperia Arc Android Development] TopperBG:
Correct is Anzu for LT15i for flash. Simply because ftf extend only /system partition. But kernel is not there. It and booloader are before whole ROM.
[Xperia Arc Android Development] r_southampton:
I'm a bit confused...

The last time I upgraded my rom (about a year ago) I had to install the basebands separately.

Are you saying that if I install vengance kernel and UHD 3.0.2 ROM then the baseband will be updated correctly?

Edit: on further reading, I think that if I install

LT18i_4.1.B.0.587_(1254-2716).zip

first

then it writes in a compatible baseband?

Thanks.

R
[Xperia Arc Android Development] Ritmasz:
Flash 587.ftf and it will give you the latest bb.
[Xperia Arc Android Development] r_southampton:
Thanks.

think I'm good to go then.

It is just me or the otg modules don´t work?

Anybody has the same problem?
[Xperia Arc Android Development] gu5t3r:
Some sticks drain too much power (especially mSD adapters), so it seems then that OTG isn't working...assuming that you have proper OTG cable...

Try another USB stick...
[Xperia Arc Android Development] TinoZgb:
which is the best governor for battery life?
[Xperia Arc Android Development] TopperBG:
For me (till now, but I've tested only 3 of them) it's Smartassv2/sio.
[Xperia Arc Android Development] blakstar:
this kernel is the best for ultimate HD 3.0.2, but can you "stabilize" the wifi in the next update. I also noticed the size of the modules is large (5.12 MB) compared to advanced stock kernel (1.5 MB) which i think has better wifi. Hope you take my advice into consideration
[Xperia Arc Android Development] bobgeneric:
Working for me.
[Xperia Arc Android Development] TopperBG:
Try then to flash modules from ASK ;)
[Xperia Arc Android Development] blakstar:
i think it works now, after wiping dalvik cache, i don't know how is it related, but it worked
[Xperia Arc Android Development] TinoZgb:
anyone else? best governor for battery life?
[Xperia Arc Android Development] gu5t3r:
Re: [KERNEL][ICS] Vengeance [ARC/S/PRO][1.32][18/02/13]

smartassV2 / sio
[Xperia Arc Android Development] :
Re: [KERNEL][ICS] Vengeance [ARC/S/PRO][1.32][18/02/13]

If I'm not wrong, ASK kernel uses stock zimage. Sony compiles it's kernels through coresourcery gcc ( as they mention in their website ) .

I compiled my kernel with latest linaro gcc 4.7.3 . Since each gcc has its own algorithm to compile code, this causes some difference in size of compiled modules ( although negligible ) .

And size shouldn't be a yardstick to categorize which module fares better? Don't you think?

Re: [KERNEL][ICS] Vengeance [ARC/S/PRO][1.32][18/02/13]

Ill take it your using the 4.7.3 toolchains from my github?? Anyway doesnt matter wether u use 4.4.3, 4.6.2, 4.7.3 whatever the toolchain is wifi modules will always end up that size. Simple reason, you are not stripping the modules after compilation.

Advanced Stock Kernel.

Any way, you can flash stock first, then try two reboots, and try again.

But with modules for Vengeance I've got times better coverage !

Dear Dev(s),

Could I ask some question about integrated CWM?

How can I change TIMEZONE in CWM backup?

Or CWM which integrated in kernel can only use GMT timezone only?

Thanks for your help and great kernel.
[Xperia Arc Android Development] El_Crosso:
Check version CWM?

Which version is included in this Kernel?
[Xperia Arc Android Development] kemoba:
Any chance for a TWRP version ?
[Xperia Arc Android Development] TopperBG:
CWM?

[Xperia Arc Android Development] dagustl:
TWRP Recovery

Hi Rachit Rawat. I´m back at your Kernel. Had 1.28 which was really good, but 1.30 drained a lot of battery.

1.32 is again amazing!

What you think about integrate TWRP in a possible new version?

Its really cool.

It also could help many people to prevent bootloops when flashing new Roms.

Thanks for your support for our ArcS. :good:

EDIT:

Ooops, have read the last 4 pages, but don´t know why i didn´t recognize that kemoba 2 posts above already asked about TWRP.

So, sorry if i annoyed you with my question.

Best Regards.
[Xperia Arc Android Development] optiplus:
Hi,

Sorry to ask but I'm a noob in Android, ehehheheheeh

1 - I made a nandroid backup of my stock rom and stock kernel, my device is unlocked Bootloader and root.

2 - After I install for example this kernel.

3 - Supose that I don´t like and want to go back and made a nandroid restore of my previous settings.

4 - Witch kernel I have after that, the stock or the new one?

Regards

Joao
[Xperia Arc Android Development] dagustl:
With a Nandroid you only backup your Android-ROM, not also the Kernel.

So your existing Kernel stays installed after the restore.

[Xperia Arc Android Development] :
I not able to test advanced stock kernel!

But on my device is this kernel fastest in all the tests than the all others kernels?

- many many faster

- everything working fine, no others kernels have CWM as this kernel

- old device from 2010- 2011 with slow processor, feels like galaxy III

- no glitches etc

This is the reason!
[Xperia Arc Android Development] kimbaduds:

[Xperia Arc Android Development] bluxe:
wait too much at sony logo so takes a long time to boot. can you reduce boot time in future releases ?

srry for my little english..
[Xperia Arc Android Development] TopperBG:
This is true, but I thought we have phones for usage, not for rebooting :)
[Xperia Arc Android Development] dagustl:
Well, it´s just a suggestion from gu5t3r, if this kernel does not work well for you. ;)
[Xperia Arc Android Development] gu5t3r:
This is because Vengeance has proper init.d implementation for Mounts2SD to work, and it's not because of kernel it's because of your init.d scripts....

If it's taking long at Kernel Boot Logo it means you have some stupid scripts in init.d like zipalign and sqlite3...

As I wrote on LuPuS thread, you need to make them relaunch in background by adding this IF line like this:

#!/system/bin/sh
if [ "$1" != "BG" ]; then $0 BG & exit 0; fi

If it's not important for phone to wait for script to finish (like mounts2sd and other a2sd scripts), add this if line and script will relaunch itself in background, phone will continue booting and script will continue executing...

If you add this in zipalign script, zipaligning will continue executing in background and phone will not wait it to finish....

It's even better to remove these scripts and use zeppelinrox's from latest SuperCharger FAST tease because he implemented checksum so if apps are already zipaligned it takes few seconds to finish, not minutes...

And his Detailing sqlite3 script can be configured to run every 10th boot and zepp run's it when phone is already booted so it does not impact boot speed....
[Xperia Arc Android Development] nokiagye:

[Xperia Arc Android Development] vashta:

[Xperia Arc Android Development] optiplus:
Hi,

Thank you for your testimony.

Can someone tell me, after install this if I return to stock I will have root or loose root, since I have stock rom with stock kernel but with root.

Regards

And sorry for noob questions, but I need to learn, eheheheheheh

Joao
[Xperia Arc Android Development] dagustl:
If you return to Sony original firmware by flashing stock with SUS or PC Companion you will loose root.

If you stay on this kernel and flash stock-firmware from Sony with Flashtool then you can select "Exclude Kernel" in Flashtool and you will not loose root, iirc.

In this case you also have to select on flashtool "No final verification".

Maybe you have to install SuperSU or Superuser again, but it depends on the kernel. Some kernels do this automatically because they have it integrated.

No problem about n00b questions, everyone has started at Zero :)

But if you have more questions about root etc then please go to the Root-thread or maybe ask gu5t3r or me with Private Messages,

cause this is a thread for the Vengeance Kernel. ;)
[Xperia Arc Android Development] ChungHung.Chen:
Sorry for popup this post.

Does anyone know how to?
[Xperia Arc Android Development] dagustl:
@ ChungHung.Chen

Don´t understand what you mean or why you want change timezone in CWM.

Timezone is not a thing about kernel.
[Xperia Arc Android Development] ChungHung.Chen:
Dear dagustl,

I know it's not in kernel, but CWM use "time stamp" for backup folder's name.

My timezone is GMT+8 (Asia/Taipei), so CWM's folder name always late for 8 hours.

In TWRP with my Nexus 7 I can set Timezone.

But I don't know how in Arc S with "in kernel CWM".

Sorry for my English and thanks for your answer.
[Xperia Arc Android Development] divest:
I have another issue:

anyone noticed arc s getting high temperature while using gps on this kernel?
[Xperia Arc Android Development] El_Crosso:
Just a question

Great kernel deserves a great logo or signature :D

Anyone coming soon? :good:
[Xperia Arc Android Development] dagustl:
Oh i understand.

Well, you can try Lupus Kernel V10. Wedgess has integrated TWRP in his Arc/S-Kernel.

But maybe also Rachit will bring it with a new version of Vengeance. :fingers-crossed:

No problem here. Which settings do you have in CPU Control?
[Xperia Arc Android Development] kAcA.:
The boot of the kernel is really slow...

Other than that, great performance and battery life! :good:
[Xperia Arc Android Development] dagustl:
@ kAcA.

Yes thats a known issue.

What i noticed is that it is different what ROM i have.

On UHD 2.0.3 its very long, but i have tested Viper Xperia 3.5 a few days ago and there the kernel screen was not visible that long.

Really strange. Anyone also noticed that ?

[Xperia Arc Android Development] gu5t3r:
It is because of proper init.d implementation and because of that Phone will stay on kernel boot logo until all init.d scripts finish executing...

In the link below I explained how to make script relaunch itself in background and allow phone to continue booting while simultaneously executing scripts.

Scripts that are probably slowing boot are zipaligning and sqlite3 db optimizing... You can make them relaunch in bg...

A2SD scripts like Mounts2SD you should not modify.

Its best to delete zipalign and sqlite3 scripts and use zeppelinrox's from SuperCharger because zepp executes them when phone is already booted thus not slowing boot...

Re: [KERNEL][ICS] Vengeance [ARC/S/PRO][1.32][18/02/13]

Right!

But while using zep's supercharger...launcher supercharge needs to be activated...which slows down my launcher...coz...scripts chash..

Any way i would i wound use only zipalign and sqlite 3..only from that script?

Copying zipalign and sqlite and pasting them in xbit would be enought to execute them on boot or using cmd?

Typed from my Iyokan!

And...Be the smart Geek! :cool:
[Xperia Arc Android Development] gu5t3r:
I'm using latest V6_SuperCharger-U9_FAST (FatAssSuperTease) tease, zepp is using some check (date think) while zipalignig so if apps are already zipaligned, script finishes in few seconds...

If raising oom priority makes your launcher slow, you should change your launcher...Because I supercharged many phones of my friends and they all said it works better after supercharging...Even SGS3...

You don't need to patch services for using the script, you can just decline all optimizations and use zipalign and sqlite3 detailing only...

Copying anything to /system/xbin does not make anything run on boot... It just makes that you can run stuff with filename only, without full path...

Copying stuff to /system/etc/init.d makes stuff run on boot...

and

99hd

which is 40+10=50 seconds of unnecessary waiting at boot logo...

Re: [KERNEL][ICS] Vengeance [ARC/S/PRO][1.32][18/02/13]

This would be to avoid waiting for some time at the Sony logo right? If that's the case, just replased the 98tweaks and the 99hd with what you said and in my mk16 it continues to take the same time.

I've supercharged the services.jar but haven't applied V6 Supercharger yet so I have no idea on what might be failing.
[Xperia Arc Android Development] knightthgink:
should it install busybox?
[Xperia Arc Android Development] TopperBG:
Not need to (but there is already inside)
[Xperia Arc Android Development] gu5t3r:
Yes, Vengeance kernel has Sony logo. Maybe you didn't add IF line right, did you try reopening the file to see if changes are saved? That can be problem on some file managers...And every space is important in:

if [ "$1" != "BG" ]; then $0 BG & exit 0; fi

...if its not entered correctly shell will just skip it as error and it would be as it is not there...what I suspect is happening to you...

On my Arc S, init.d scripts start executing when Sony logo becomes brighter, and with SuperCharger and KAK it only takes 2-3 seconds...After I turned sd-ext file system check on boot in Mounts2SD it takes me 5-6 seconds to boot now...

And this method works for sure, because I have script for setting cpu governor that waits for property sys.boot_completed to be set before setting governor, and if I remove IF line script does not get relaunched in background, and Phone is waiting for script to finish and script is waiting for Phone to boot which never happens and phone gets stuck at boot logo... With IF line script gets relaunched in background, phone continues booting, when phone is booted (property is set) script sets cpu governor and governor options...

---------- Post added at 04:08 PM ---------- Previous post was at 03:48 PM ----------

This should have same effect but works in slightly different way:

if [ "0$BG" -eq 0 ]; then export BG=1; $0 & exit 0; else unset BG; fi
