After flashing boot.img: (v01), I'm experiencing a noticeable lag with the build-in Chinese Input..

I reflash the 4.0 ttf and wipe data, everything works smooth again.

Can you take a look at this matter plz? Thanks.

And also do you mind if I ask, if there are other ways of rooting without changing kernel? It would be preferable because I really need the Chinese input to be working.

anw, thanks again for the hard work =]
[Xperia Arc Android Development] DooMLoRD:
hi... i dont think the Chinese input kb lag is directly related to kernel..

have u tried wiping cache/data via recovery when u were on the prerooted kernel?

currently there is no other solution for rooting... but there might be a solution which i am planning to test out soon... but thats for bootloader locked phones...
[Xperia Arc Android Development] YouZi:
Thanks for the quick reply :)

After I few times trying, I found that it is not just the Chinese input kb thats lagging.. in fact, the entire phone is noticeably slower compare to the before-fastboot-flashing...

I don't quite get how to "wiping cache/data via recovery".

What I did is:

1.flash LT15i_4.0.A.2.368_Generic Global using flashtool, with wipe data ticked.

2. follow the 1-6 installation steps in your post.

Did I meant to do something else before the 6-steps?

Cheers. =]
[Xperia Arc Android Development] ShyamSasi:
I noticed slight lags.. But after applying the SuperCharger Script now it's working great.
[Xperia Arc Android Development] bmwbasti:
Can you give us some more informations about that please ;) ?
[Xperia Arc Android Development] spida_singh:
+1 :-D

all in good time i guess. Thanks for the heads up.
[Xperia Arc Android Development] DooMLoRD:
just check if the lag is also there in the stock FW...
[Xperia Arc Android Development] YouZi:
No, it does not lag when I flash the stock FW using flashtool.

(I assume this action flash back the stock kernel then?)
[Xperia Arc Android Development] DooMLoRD:

will be posting new kernel soon (a day or two)...
[Xperia Arc Android Development] DooMLoRD:

also hold on... v13 is in the works :P
[Xperia Arc Android Development] rahul.pillai:
Noticed something weird, battery drains less when on 3G (Airtel B'lore) compared to 2G with FW .42

On a different note, SU binaries cannot be updated to the latest.

sorry,i hav some problems..

my fastboot can't detect my phone. it's still show "Waiting For Device" and i can't flash boot.img

how can i fix the problem. THX for help
[Xperia Arc Android Development] tRippinthehead:
possible rapid battery drain related with the loss of the network and the frequent search for it?
[Xperia Arc Android Development] Flo95:
Is your phone booting into fastboot?
[Xperia Arc Android Development] Deaw^^:
Yes,I press MENU Button and the light turns to blue..
[Xperia Arc Android Development] Flo95:
That's strange then.

Did you unlock your bootloader?

SE wrote on there unlocking site that your device's bl can't be unlocked if the LED doesn't turn blue OR it says just "waiting for device".

In the general section there's a thread for remote unlock, that's the way to go for you then
[Xperia Arc Android Development] Deaw^^:
thanks for help.i still hav a problem but i try this and it's works for me. :)
[Xperia Arc Android Development] chitose_ndy:
Testing the v12 cwm mod using .42 fw.

Will report back after sometime.

:)

Edit:

Okay it works well with no problem,

But the battery lives longer with the old v12..

Maybe because the old v12 has the undervolt feature..
[Xperia Arc Android Development] DooMLoRD:

As I know, flashing kernel do not clean your data, but it's a good habit to back-up your data before doing something new.

[Xperia Arc Android Development] Flo95:
Installed V13, works good and didn't wipe anything.

To the problem I have with my sd and recovery (sd can't be mounted):

Would formatting my sd help?

And if yes, how should I format it:

1. with my computer

2. with recovery

3. with the phone settings/storage/format sd card?

When I copy everything on my sd over to my computer the apps on the sd get backed up, too, don't they?

Starting to annoy me to not have the ability to make nandroids etc
[Xperia Arc Android Development] tRippinthehead:
thanks for update DoomLord, will test new version )
[Xperia Arc Android Development] DooMLoRD:
Best do it via android OS ... settings -> storage -> format sdcard

Waiting for 1.6ghz version ;)
[Xperia Arc Android Development] chitose_ndy:
Okay, have been using the v13 kernel for 24 hours.

No problems I guess,

But is it just me or the battery drains more than the old v12?

Well.. need more opinion..

Maybe its just me..
[Xperia Arc Android Development] Flo95:

That finally fixed it. I could access the sd card with CWM :)

So everything works fine. The only issue is that CPUSpy reports deep sleep as an unused frequency. This is for version 12 and 13. I'm using 42 firmware. Any ideas? Is this a bug with CPUSpy?
[Xperia Arc Android Development] Flo95:
Works for me. Using .42 with V13 :)
[Xperia Arc Android Development] megacrazy:
Hmmm ok so version 12 never showed deep sleep. Version 13 went into deep sleep (albeit for 8 seconds but it did). Hmmm maybe some background app keeps doing stuff even when off. Ok...so it works great in that case :)
[Xperia Arc Android Development] chitose_ndy:
What is a deep sleep?

Sorry for a noob question..
[Xperia Arc Android Development] Flo95:
When the CPU is almost off and doesn't consum much battery.
[Xperia Arc Android Development] chitose_ndy:
I see..
[Xperia Arc Android Development] tw1tterik:

[Xperia Arc Android Development] birdcut:
LT18i is Arc S. So don't flash that firmware to your phone.
[Xperia Arc Android Development] le_manhpro:
Hi Doom !

Allmost everything works untill the stock se photo viewing app in camera so the loss of DRM isn't that bad ;)
[Xperia Arc Android Development] DooMLoRD:
ah i dont really care abt drm stuff... as long as i can flash kernels happily :P
[Xperia Arc Android Development] JasonStein:
Hi DooM,#13 is quite good to use and also powersaving but can you make default governor in config file before you compile the kernel?Since you set default governor and other settings in your ramdisk so I can not use script to change the settings including governor.At first I don't know what's going on but finally I found you have set it in your ramdisk init.semc.rc file.I delete it then my script works.

:D I forgot to tell you the official kernel can not boot MIUI,you need to use the sources from FXP and also the ramdisk and you'd better do some tweaks.I can send you my config file today.

Best regards,

JasonStein

P.S. I love your ramdisk.:cool:
[Xperia Arc Android Development] DooMLoRD:
yes i know abt the diff kernel part...

but u can always override ramdisk default governor... just have a init.d script which will take care of that
[Xperia Arc Android Development] JasonStein:
Init.d script won't change the governor because you just put those settings after the loader running init.d scripts.After my script works,your ramdisk rewrite it again.:D
[Xperia Arc Android Development] DooMLoRD:
no thats wrong...

init.d scripts are executed at last... so they will work...

btw those are not my changes... thats how the original se ramdisk is:

https://github.com/DooMLoRD/Xperia-2011-Official-Ramdisks/tree/master/ARC
[Xperia Arc Android Development] JasonStein:
Ok,I got it,but before I delete the default setting in the ramdisk, the script didn't work which makes me confused but I will check it again when I get home.

Thx for your reply.;)
[Xperia Arc Android Development] DooMLoRD:
no problem... it would only bother rom cooks/devs as they may want to select a governor of their choice...
[Xperia Arc Android Development] JasonStein:
Yes,you are right.

I have learned a lot from your kernel sources and ramdisk.

Let's have a bottle of coke.:rolleyes:
[Xperia Arc Android Development] chitose_ndy:
Can't agree more about that :p

I think its worthed to lose drm but having doomkernel.

Being able to OC is better than stay stock.

:p
[Xperia Arc Android Development] DemonicHawk:
Flashed v13 just a little while ago, it definitely fixed the battery drain that was present in v12. Very happy now and the changes in CWM (especially not having a million "no" options) are very much appreciated!
[Xperia Arc Android Development] zohaib0001:
Still using so much Battery in deep sleep

Hy i am on 2.3.4 _ 42 firmware having Xperia Arc

I flash kernel 13

i did not increase the cpu speed just set it on original 1Ghz

But it still using 5% battery in every Four hours when phone in deep sleep

this ratio is to much high

please can you make a kernel that is based on original one and just add the CWM recovery in it nothing more

i think the over clocking mod in your kernel is the main reason of battery drain quickly either we using over clocking or not battery still drain quickly.

now i return back in stock kernel its use 1% battery in every four hours in deep sleep.......
[Xperia Arc Android Development] cezarL:
Just curious... is that low drain with the phone in airplane mode? This is a question for everyone that has reported great battery management, actually.

I've tried stock, custom (stock-based) and CM7 ROMs on my Arc S, with botj stock and custom kernels, and with every one of them I always lose around 1.5-2% per hour in DeepSleep (data connection off, WiFi on)...
[Xperia Arc Android Development] hygge:
I have a battery drain of 1% per 2-3 hours in deepsleep. That is with data, wifi, bluetooth and gps off and running doom v10.

My battery drain has increased to 1-2% per hour on v11, v12 and v13. Currently running on v13 but will probably go back to v10 for the low battery drain.

I am running the same scripts setting voltage, scheduler and clock speed. Only difference is the kernel version.
[Xperia Arc Android Development] DooMLoRD:
not immediately... but it will be fixed in next release
[Xperia Arc Android Development] le_manhpro:
Hi DooM!

I see this version v13 drain the battery fully charged so much that I use in 3 hours, the battery is 15% hixx I have a 2.0GHz overclock using my xperia Arc S sr my english so bad:mad:
[Xperia Arc Android Development] cezarL:
Trouble is... you guys with Arc devices can always go back to v10 (or BlendKernel v2), but for us Arc S owners that's not an option, v10 is not compatible :(

But at least this confirms (sort of) that it's not a problem with my device, it has to do with the software (recent firmwares, since the newer kernels are based on those).
[Xperia Arc Android Development] ShyamSasi:
Since your working a tweaking Recovery I had a small suggestion, When I was using HTC we used to have this option in Recovery "Wipe All"

Is it possible to do the same in ours? It's comes handy when we are switching between ROMs
[Xperia Arc Android Development] DooMLoRD:
factory reset is ment specifically for this... it wipes /cache and /data... why do u need to wipe /system, /data, /cache at a go? all this should be handled by updater-script (format system) command for ROM installation...

and specifically for semc devices its VERY dangerous as offline charging depends on correct files in /system... if u wipe /system and flashing of ROM fails (and if u are on low battery) u will be in BIG trouble...
[Xperia Arc Android Development] Flo95:
You used it 3 hours long or was it 3 hours in idle?

Do you use undervolting?

If not, 2GHz will drain the battery quite a lot.
[Xperia Arc Android Development] ShyamSasi:
Oh ok. If it's too dangerous lets stay away from it ;)
[Xperia Arc Android Development] erwin929:
Are you saying tht we can actualy use v-10 kernel with the last 402. firmware???

I think that the newer firmwares are incompatible with the older kernels

And also if I may add that the v-10 is based on 301. firmware with android 2.3.3
[Xperia Arc Android Development] le_manhpro:
I use it in 3 hours and not undervolting:mad:, so there is less demand on the batteries?? / sr my english is not good
[Xperia Arc Android Development] tRippinthehead:
new kernel shows better battery life time ;)
[Xperia Arc Android Development] hygge:
Yes, v10 is also working on the new firmware releases except for two functions. Vibration is not working and usb to pc is somewhat limited. You can with "multi mount" from the marked browse your sd card on you Arc running v10 on newer firmware.

You are unable to mount the sd card in windows/mac without multi mount installed.
[Xperia Arc Android Development] erwin929:
well, no so in muy case

full discharge in les than 20 hours

using latest 402. firmware overclocked to 1.2Ghz (nofrills>>ondemand-noop)

all sinconizations are in automatic

3G, WiFi and BT are all on. GPS off

I've calculated about 3%+ batery consuption per hour in standbuy mode (I don't use deep sleep)
[Xperia Arc Android Development] chitose_ndy:

And i'm also having sometimes random reboots while listening to music...
[Xperia Arc Android Development] Flo95:
Random reboots can be caused by too much overclock or too much undervolt. Check for that

@ Doom:

Thanks for the new version. Gonna flash it later when I'm done with studying for today.
[Xperia Arc Android Development] Flo95:
I found a bug:

The backlight of the 3 hardware buttons doesn't go on anymore, just to show when you have to press the back button for recovery, but not when you use the phone/when it's turned on.

Hopefully you can fix that asap

And after the first boot I got Xperia Hot Shots, UEFA and McFee Security back... Just deleted them again and they didn't appear after another reboot anymore.

Should we reflash the kernel? Or how can we fix it, if it works for you?

Might it because of the new busybox version, as SuperCharger V6 requires 1.18.2 or lower?

Will it cause problems if I install it in another direction?
