It's much more practical this way...:) Thank you...:) Why is CWM on video is in Cyan color and ours is Red? Can you make it in Cyan too?

Thanks in advance...:)

---------- Post added 27th December 2011 at 12:52 AM ---------- Previous post was 26th December 2011 at 11:53 PM ----------

DooMLord, I just have one question...:) Did you make some changes in New Kernel .img file other then new CMW? I managed to change SPlash screen on Old Kernel .img but in new one when I replace .rle file and repack .img the file flashed but my phone don't boot...:( If I just remove original .rle file its OK but with the same edited .rle file (which I used in old kernel) it can't boot...:(

Thanks in advance...:)
[Xperia Arc Android Development] Jinx13:
Are the modules the same?
[Xperia Arc Android Development] kickerz14:
Noobie question, can I still use my pc companion even though I used this kernel? Thanks!
[Xperia Arc Android Development] adrianom:
I have this problem wan I use a image which have a very big file size, maybe the new ramdisk have a bigger size and your logo.rle have to be small.
[Xperia Arc Android Development] adamtan:
quick question. if i fastboot the img file, will i lose my stuff on my phone?
[Xperia Arc Android Development] Ninolina:
Thanks for the tip. I will try smaller .rle file. :-) Did you manage to change the splash screen in this newest version of DoomKernel? Thanks again...:-)
[Xperia Arc Android Development] adamtan:
ok i answered my own question. Cant wait to update this new version.

did a backup and fastboot the img, and glad to say that everything is intact without need to restore.

Thanks Doomlord!
[Xperia Arc Android Development] DooMLoRD:
the original CWM5 has cyan color... i dont like it at all... so changed it to RED :D

there are multiple reasons for that to not work... check ur setup and use LINUX...

wifi modules same as v15...

NO... u will need to RELOCK BOOTLOADER before using PC Companion..
[Xperia Arc Android Development] Jinx13:
Thankss :)

That depends what method was used to unlock the bootloader ;) If unlocked the official way then yes the bootloader will need to be relocked :)

[Xperia Arc Android Development] adrianom:
No, I still dont tried with the new version.

Hi,

My problem :

- Install of doomlord modules : WIFI is OK but GSM DATA KO

- Install of stock modules : WIFI is KO and GSM DATA OK

Have you any ideas ?

Best regards.
[Xperia Arc Android Development] ishishkin:
Hi, Doom... There is a thread where some guy said that he is using .62 firmware with -64 baseband as it is, but flashed .283 kernel... that way he managed awsome battery life...as he is saying... So maybe you could manage your kernel to these .283 basics if it is possible...for us to test it... It wold be awsome if we could have these battery life with your kernel...so if you got some time... Thx...
[Xperia Arc Android Development] Ninolina:
I did it with newest version too...:) It was the problem with the too big .rle file...:) Now its working after I make it a little smaller...:)

Thanks again...:)
[Xperia Arc Android Development] tRippinthehead:
I think that the situation would not change. But if the kernel will be made for testing, I'll be happy to test it.

Is there anyone can show me how to patch two way call recording for xperia neo? I can see DooMLoRD did on v15 arc. But I don't know how he could do it so that I can do the same on my xperia neo.

Will we also get to see a Kernel for the Xperia Pro? I love your work but got a Pro now even tho it's not that well supported yet by the xda community.
[Xperia Arc Android Development] grizzlyspid86:
So is the v09 kernel is the last kernel by you for Xperia neo? Or can I use this Arc kernel?

Edited: ok, never mine, i just found out that it wont work with Xperia neo.
[Xperia Arc Android Development] alfiemenace:
can we have a comprehensive description on governors and schedulers? :( google doesn't seem to have the answer to everything. :( really please? :(

nope i wont be developing kernels for that... and anyways one of the users had contacted me regarding that device... he was planning to use my kernel sources and get them compiled for PRO...

test atleast for 1-2 days

please test out if there are any improvements in battery life...

i have posted similar test kernels for PLAY too...

i hope everyone will be helping in testing... cause if everyone isnt helping out in testing then the next time i hear ppl complain abt battery drain i will just close this kernel thread...

before u report any battery drain issues please read this:

also while reporting ur battery test kindly post the following screenshots:

cool!

do tell me ur personal opinion about the next SE/Sony flagship device
[Xperia Arc Android Development] Ninolina:
Even that my ARC S is initially on 1,4GHz should I also put CPU frq max to 1GHz? It would be downclock or not?

I always use 1,4GHz so if I now put 1GHz then I will not be able to compare it with earlier standard use of my device...:(
[Xperia Arc Android Development] DooMLoRD:
ofcourse u use it at 1.4Ghz ;)

use the stock clock speeds for ur device :P

After 6 hours drain is @ 10% compared to normally 30% for same period.

I think I will just continue for now and change it tomorrow morning just to see have it behave as I normally also charge i the evening.

1,5% per hour without WiFi, Backgrounddata off, pushmail off

2-2,5% per hour with WiFi, BackgroundData and push mail on

hello everyone...

there will be BIG changes in the kernel from next release... basically all the extra stuff/features will be converted to modules... all the modules will be provided in kernel ramdisk so u dont need to separately download anything...

i will also provide an app to select the features (modules) u want to enable from next bootup... just select the features u want and from next boot only those features will be active...

because of these changes the next release will take time...

but till then u can kindly help out by testing the TEST kernels...

Thanks doom! A big help.

Just flashed test1.

Is it advisable to wipe battery stats on every test?

Will post screenshots and battery stat text file before my next charge cycle.

Thanks!!
[Xperia Arc Android Development] iridaki:
When you wipe batterystats, you might notice that the battery percentage decreases quicker and inconsistenly. So if you do, make sure you test the kernel for minimum 2 full battery cycles.

Personally, I do not wipe batterystats more than once per 2-3 months.

Make sure you wipe cache and dalvik though and give the device 10-15 minutes to regenerate them after first boot. ;)

Hi Doomlord

After installing kernel on .62 ftf, CPU is not stable on 1.6, 1.5, 1.4; the phone is restarting at those frequencies. Is it normal?
[Xperia Arc Android Development] DooMLoRD:
some devices cannot handle overclock...
[Xperia Arc Android Development] cx-11:
mabe a small bug ????

So I'm not sure, but if I use kernel with 4016 stand at a place with a weak wireless lan connection (display bar display about 2), and then connect with a network cpu-min/max134/1018 press is up to the connection the W-lan even weaker or falls with the connection to the router again from the wide receiver-no-connection-

after receiving the completed IP and connection to the router is the indicator bar back stronger (about 2 bar indicator display again)

Please check with your device but maybe every kernel version does it?

134 MHz with under volt but no problems with interactive governor from time to crash, but works well ineractiveX

Maybe I'm wrong with my remarks.

tonight will fully recharge kernel 4016 and to leave untouched on my alarm clock

tomorrow night with screenshots

sorry for the google translation;)
[Xperia Arc Android Development] DooMLoRD:
the governors havent been updated to support the modified frequencies...

thats why i requested everyone to test using stock settings :)
