Using v20 with stock 757 (c6683)working super since release
[Sony Xperia Z Ultra] gasland:
I am trying to find a live link
[Sony Xperia Z Ultra] :
I have installed xposed and few modules, but that doesn't make sense on stock kernel there is no reboots : (
[Sony Xperia Z Ultra] shaolin95:
First rule of troubleshooting is to get rid of any variables and extras and go back to the basic...does it run with stock rom (without any add on) without rebooting?
[Sony Xperia Z Ultra] Jokerank:
V20 random reboots :(
[Sony Xperia Z Ultra] pemell:
I didn't have a single random reboot.

Governor: on-demand

Dynamic fsync off
[Sony Xperia Z Ultra] arceles:
A hugely necessary feature....

Dear DoomLord, would you be so kind to port the Z2 feature to the xperia ultra? particularly, the one mentioned in the post http://xdaforums.com/showthread.php?t=2635196&page=2 ? It would be hugely appreciated! :D
[Sony Xperia Z Ultra] skarfreak:
hi, i'm a novice user of this gigantic awesome phone. It's just been a month since I purchased it. I got it rooted through EasyTool Root and has dual recovery working too. One quick question though... Is my device ready for unlocking the boot loader right? I need to unlock it before flashing this awesome kernel...?? Thanks kind people for understanding...
[Sony Xperia Z Ultra] dbolivar:
So if there is no DT2W you won't enjoy the kernel? :) Well the thing is that the touchscreen is one of the few differences between the Z1 and ZU hardware. I will try to merge what [MENTION=3223392]reaper61616[/MENTION] and [MENTION=3534362]blueether[/MENTION] have been working on, if it doesn't mean a huge change in the kernel code. But I will work on that only after if proves to be stable enough, i.e., after more comments for more days on their threads that it's reliable and don't have an impact on battery life.

BTW, what is the power drain you mentioned? I'm experiencing great battery life with this kernel. Or were you talking about the DT2W?
[Sony Xperia Z Ultra] MEGAX91:
Unfortunately CPU overclocking to 2.3 is not Available in original v11 kernel but you can overclock GPU to 533MHz using Pimp my z1 app.

also LCD Color Control is not Available in this port.

sound control is awesome also battery life is better than stock kernel.

Thanks dbolivar
[Sony Xperia Z Ultra] venorme:
I was talking about drain of stock after kitkat - hope yours will fix it.
[Sony Xperia Z Ultra] dbolivar:
You can indeed get more battery life with this kernel, by choosing a different CPU governor and tweaking its parameters. Try, for instance, wheatley or intellidemand. However it's more a workaround than a proper fix, which can only come from Sony with a newer version.
[Sony Xperia Z Ultra] cfbruck:
Mine with latest Monx gets soft-bricked (vibrates and black screen) with this, any idea why?
[Sony Xperia Z Ultra] blueether:
Well with a bit of quick testing DooMKerneL all seems good

[MENTION=4972043]dbolivar[/MENTION], the quick port of dt2w that I did lastnight didn't want to boot system but did boot into recovery OK, I guess I need to get the .config right :)
[Sony Xperia Z Ultra] joluke:
[MENTION=4972043]dbolivar[/MENTION]: add this to OP :) :good:

Flash the full 14.3.A.0.681 FTF > flash CWM kernel > wipe data, /cache and dalvik-cache > install Monx & update v03-03 > boot > reboot into recovery > flash doomkernel V11 > PROFIT!

I did this... no issues
[Sony Xperia Z Ultra] dbolivar:
Thanks a lot my friend! Added to the OP!
[Sony Xperia Z Ultra] dbolivar:
Weird, what is your model (C6833, C6802 etc.)? Is your bootloader unlocked?
[Sony Xperia Z Ultra] appleknight:
Been running it since therapy u released it, no problems here
[Sony Xperia Z Ultra] blueether:
Don't be so quick to say you have no problems especially if you are in therapy...

:silly:
[Sony Xperia Z Ultra] skylinestan:
Dev should inform others bout this kernel needs to be on unlocked bootloader to get it working..not for locked bootloader

Sent from my C6802 MONXdified ROM
[Sony Xperia Z Ultra] cfbruck:
Yes, stupid me, I haven't unlocked mine :) Yet...
[Sony Xperia Z Ultra] kipue:
Hi, came back to report that all is good.

Big thanks, you made it possible for me to enjoy my new phone :) the only phone I had with an equally bad battery life was the Nexus 4, and boy it's no fun :'(

I've put it today through a typical day for me and the difference with stock kernel is not placebo I would say.

(UC to 1800, intellidemand, could try to UV too)
[Sony Xperia Z Ultra] pemell:
Thanks [MENTION=4972043]dbolivar[/MENTION]

Finally my ultra feels completed. It's rock stable and everything is working excellent.
[Sony Xperia Z Ultra] godraxe:
plz leave stock bootlogo
[Sony Xperia Z Ultra] pemell:
First: dbolivar won't change anything else besides making it compatible with our device.

Second: if you're using doomkernel, it's doomkernel boot logo.

No offence though :)
[Sony Xperia Z Ultra] blueether:
How often do you see the bootlogo to be worried about it?
[Sony Xperia Z Ultra] dbolivar:
DT2W: so guys, I have made some tests with the DT2W code merged into the kernel. It's not reliable at all, sometimes it works, sometimes it doesn't, matching the reports I've read. So, I won't include it until it's working 100%. It's much more reliable to just press the power button, and honestly the DT2W seems more like something "cool" to show to your friends than a real feature (unless the power button is broken). But taste is taste, I won't judge it, will be included once reliable. :)

Boot logo: it's been asked to DooMLoRD himself before, and he doesn't want to change it. It's his kernel so I think it's fair, some like it, some doesn't.
[Sony Xperia Z Ultra] blueether:
Yes you will need to unlock the bootloader to flash this kernel. Read the stickies about TA backup

BEFORE

unlocking
[Sony Xperia Z Ultra] skarfreak:
thank you.. just did the back up TA Partition...

So when I will UNLOCK the BOATLOADER, my files and apps/data will all be wiped out right.? How about my sdcard? will it be affected too?

Will my ROOT and dual Recovery remains after unlocking then bootloader?
[Sony Xperia Z Ultra] blueether:
External will be fine, or you could remove it

I cant remember about root/recovery, I think it just formats /data?

It doesn't really matter anyway as you will be flashing this kernel with it's recoveries and if su has gone just flash supersu from recovery
[Sony Xperia Z Ultra] skarfreak:
thanks man... so this is what happened.. i backed up all my files/data using app2zip if im sayingit correctly.. Anyway, flashing the kernel is very successful. Checked my root and dual recovery, good God it's still there. Put back the mini sd card, hoping i could flash the .zip file of my back up files/data, alas, it won't read, resulting to damage to sd card. bummer... Anyway, I managed to reformat it, fresh light and clean. Back to zero... So I got the DoomKernel, what's next?
[Sony Xperia Z Ultra] blueether:
You may want to tweak the hell out of it ;)

Pimp my Z1 is a good free app, but there are others around as well
[Sony Xperia Z Ultra] Saatvik Shukla:
I have just one question.

Is it compatable with monxDIFIED.

P.S. I know its lame but i am very new to the device so please excuse my lameness for a moment.

I am already running monxDIFIED on stock kernel, if i flash the DooM Kernel now will it be fine? because i tried it once before and i was not able to get things as they should.
[Sony Xperia Z Ultra] iBuzman:
^^ short and sweet, yes.
[Sony Xperia Z Ultra] skarfreak:
Tap 2 wake is not supported ?
[Sony Xperia Z Ultra] blueether:
short: no
[Sony Xperia Z Ultra] skarfreak:
any other apps you can recommend besides PIMP MY Z1.? thanks in advance man...

and also one thing.. in pimp my z1, it says in TOUCH SCREEN section that our kernel doesnt support PEN MODE,.. tried the pencil, it never did... this is normal right...
[Sony Xperia Z Ultra] blueether:
Pen/pencil are supproted, it just uses a different touckscreen driver that pimp my Z1 knows nothing about. The pen pencil need to be quite thick tipped to work. ie not fine tipped pen or sharp pencils

As for apps, there were some others mentioned in the thread somewhere
[Sony Xperia Z Ultra] tr0teK:
Updated from v18 to v20 with recovery. Works fine
[Sony Xperia Z Ultra] iBuzman:
Hey [MENTION=2784807]DooMLoRD[/MENTION],

I have a 4.4.4 ftf and also a system dump - is there anything I can provide you with to help you update to 4.4.4?

thanks mate :)
[Sony Xperia Z Ultra] DooMLoRD:
just the kernel sources thank you!
[Sony Xperia Z Ultra] WildBit:
Excellent and just in time since the v20 kernel is not working with the new 444 update, or at least "out of the box". I will run some tests in the meantime with the new release
[Sony Xperia Z Ultra] tr0teK:
After some time using v20 still getting random reboots. I am using it with monxdified rom. 757
[Sony Xperia Z Ultra] joluke:
Change your governor to interactive. And POST LOGS
[Sony Xperia Z Ultra] tr0teK:
Nevermind changed my rom and kernel already. Anyways thanks for trying to help
[Sony Xperia Z Ultra] WildBit:
It's got nothing to do with the ROM and/or Kernel but you will have to use a standard governor like the Interactive
[Sony Xperia Z Ultra] joluke:
That's what I told him, to change governor only. It would solve it.
[Sony Xperia Z Ultra] dbolivar:
14.4.A.0.108 sources available

[MENTION=2784807]DooMLoRD[/MENTION] , Sony released the kernel source for version 14.4.A.0.108 at Developer World website:

14.4.A.0.108
[Sony Xperia Z Ultra] tr0teK:
Thanks for the info guys. Well it works now without problems
[Sony Xperia Z Ultra] maxld:
Guys, just to make sure: is this kernel working with .108 or do we have to wait for the Doomlord to update it?
[Sony Xperia Z Ultra] samorgs:
Wait, does not work with 108.
[Sony Xperia Z Ultra] asj2583:
If i'm running Gpe rom on my Xperia Z Ultra do i use this kernal or the one for Gpe Z Ultra? Thanks in advance.

There is no source on github yet, but the next one (133) is on the sony dev site: http://developer.sonymobile.com/dow...s/open-source-archive-for-build-14-4-a-0-133/

https://mega.co.nz/#!chcV3TzS!VVexOGnZFUhmyvjTXGg7CZjzNWnJISRUQW84yyA_Rew

I suspect that is is a vodafone only bump so is the same kernel as 108?
[Sony Xperia Z Ultra] Saatvik Shukla:
As of now what we use as the latest stock is .108 on international zu

On 4.4.4 none. Wait for next release...
[Sony Xperia Z Ultra] nedooo:
What is:

added and enabled LCD Color Control

We have in stock ROM inbuilt white balance in display settings, does this adds higher level of screen adjustment?
[Sony Xperia Z Ultra] blueether:
white balance came after [MENTION=2784807]DooMLoRD[/MENTION] first made the kernel

[MENTION=2784807]DooMLoRD[/MENTION], please please please find a way to install this on a carrier locked bootloader. I.e bootloader unlock allowed :no. I really want this kernel but my z ultra is carrier is locked. Is there a way, if not, can I humbly request you for one ?

The latest GPe DoomKernel works great on Scrubber's GPe Port. I am using it right now.

On the other hand, this kernel doesn't work. The device can't boot the GPe ROM with it, which worked on the old v20.

So for now, use DoomKernel v02 for the GPe ROM.

you make a nandroid backup before you flash the kernel, then you can just restore that...

You can just flash the kernel from a FTF with flashtool

[Sony Xperia Z Ultra] adfurgerson:
Give me a couple minutes to test and I will get back to you.

Okay if you want to stay with this kernel there is xperia reboot app for purchase, or you could flash the XZDualRecovery zip from CWM. Here is link select locked or not depending on your bootloader status, I tested on unlocked and it worked fine.

http://nut.xperia-files.com/

You can also download zip and find boot image in temp folder of zip using flashtool.
[Sony Xperia Z Ultra] nedooo:
Thanks, but I tried this before still reboots first to CWM, never mind wil try to flash stock kernel with flashtool, and that new Chinese ROM 1.4

Thanks a lot again :)
[Sony Xperia Z Ultra] adfurgerson:
How are you booting to recovery?
[Sony Xperia Z Ultra] nedooo:
With NDR utils that are included in NUT's zip and with advanced power menu within gravity box module in xposed framework...
[Sony Xperia Z Ultra] adfurgerson:
NDR utils is for nuts kernel which you can go back to, or use this app https://play.google.com/store/apps/details?id=com.doomlord.xperiareboot&hl=en for DooMKernel.
[Sony Xperia Z Ultra] blueether:
or just use the volume rocker during boot
