No...

@all

This kernel (in this thread) is for stock Sony ROMs (or ROMs based on stock sony ROM)...

The kernel posted in the ZU_GPe thread is for GPe ROMs
[Sony Xperia Z Ultra] Feodorus 4PDA:
Dear DooMLoRD, tell please, you have version 22, and on phone shows v21.

TWRP version 2.7.0.0. CWM version 6.0.4.7

It will be corrected in upcoming version? Thanks.

I'd like to mention about the Intelliplug here.

I'm not able to turn it on, and define the no. Of cores to keep active.

The Intelliplug switch turns on, but for only as long as i stay at that screen.
[Sony Xperia Z Ultra] blazta:
Works for me

Anyone got this kernel running on GPe port for C6833 ?
[Sony Xperia Z Ultra] blueether:
use the GPe version, it's reported to work well
[Sony Xperia Z Ultra] diji1:
I don't know what the damn issue is but I'm assuming I'm the only one having it since searching this thread turned up nothing: when I flash the file in Team Win Recovery I get a zip verification error. Downloaded the file 3 times, did steps again to make sure I was replacing files and so on ...

... and ideas? This is odd.

[Edit: I flashed the file using CWM and it worked as per usual - I have no idea why it didn't work in TWRP.]

No Display after installing the Kernel

Need urgent assistance, after installing the kernel the phone booted but there is no display.

How do I get this working again. Please help :(

Am able to get into recovery bit once it restarts there is no display again.
[Sony Xperia Z Ultra] blueether:
Did you make a backup before flashing a new kernel? If so just restore that. If not then we need more info, Locked BL? ROM/firmware version? Model?
[Sony Xperia Z Ultra] kidrock23:
Good news V20 worked.

Same issue with V22. No Display. :(.
[Sony Xperia Z Ultra] ch3mn3y:
Are u using .757 or .631 4.4.2 fw? Coz v22 works only with .108 4.4.4 fw

Sent using C6833 - AICP/GreatDevs
[Sony Xperia Z Ultra] kidrock23:
4.4.2

Build: 14.3.A.0.757

It meets the requirements for installing v22 hopefully.
[Sony Xperia Z Ultra] ch3mn3y:
Quoting first post:

v22 is for .108/.118

for .757 it can work, but as u see it doesnt

Probably Sony (and Google) change something in 4.4.4 compared to 4.4.2, which make newer versions of doomkernel unusable on older fws
[Sony Xperia Z Ultra] kidrock23:
Am on 4.4.2 so it should work. Anyone else on the same version having no display with V22?
[Sony Xperia Z Ultra] Triflot:
No, ch3mn3y is right. The table states that v20 is the last to support firmware .757.

You'll have to either use v20 on .757, or update your firmware to .108/.118 to use v22. :good:
[Sony Xperia Z Ultra] kidrock23:
My wrong :) v20 it should be :)

Thanks for the help guys !

U can always update to newest fw

Just got the phone so still learning. Certainly not as easy as the Note :)

I don't think the 4.4.4 is available for India. So will wait.

ch3mn3y if you don't mind. I had a few queries on reverting back to stock if its fine with you.

It is faux clock.

Sent from my Nexus 7
[Sony Xperia Z Ultra] pride007.2012:
In faux setting I have over clocked GPU clock to 533 MHz but in monitor app 487 MHz is the max usable frequency. Which means the GPU can be only over clocked till 487 MHz not 533 MHz because on load it never goes more then 487.

This is a bug, just tried to point out.

I am trying to incease the mA when charging from AC through the battery controls sub menu in Faux123 kernel enchantment pro but no matter what i set there is no effect at all. My phone's max charge rate is 1250-1300 mA using a Samsung 2000mA travel charger (monitored with current widget). Is this normal???
[Sony Xperia Z Ultra] blueether:
Is that including the ~300 to 500mA for a running ZU with the screen on? If not then that that is about the max I've seen mine draw (1800mA on a 2000mA charger)

No wiping instructions in OP. Do U need to wipe System for some reason?

Thanks
[Sony Xperia Z Ultra] Triflot:
That's odd. Is your bootloader unlocked? And the system worked fine before flashing DooMKernel?
[Sony Xperia Z Ultra] rockky:
Thanks for the input.

My bad. I have 3 of these Ultra's and was damn sure I'd unlocked the BL. Not so. !
[Sony Xperia Z Ultra] pride007.2012:
If your boot loader is unlocked and flashing from cm and twrp is not working then use the flashtool. It will work fine.

can i flash this kernel with locked bootloader :confused:
[Sony Xperia Z Ultra] madsponge26:
Well wait to test the dt2w.. If they dont like the bootlogo, dont use this kernel as simple as that:D
[Sony Xperia Z Ultra] kipue:
Agreed, kernel is good, so what about that short logo?

Only thing I can think of is that it shows that the phone is not on stock software very obviously, can be a problem for resell value?

So how do you like it on .681 my friend? Any impressions from you are always valuable for my decisions :good:
[Sony Xperia Z Ultra] iBuzman:
I stand to be corrected, by surely a 4.4.2 kernel would fail to boot on 4.3(??????)
[Sony Xperia Z Ultra] LordManhattan:
It says that it should work on stock 4.2.2, 4.3 and 4.4.2 in DoomLord's thread, but I don't know how OP has built this one, so I have no idea if it works on pre-KitKat ROMs, but my guess is no.

I'm getting my Ultra back tomorrow with a new screen (woo!), so I haven't really used 681 that much, but it's not perfect. It's stable and a daily driver, but 4.3 seems a little smoother and faster. 4.4 has a few hickups and stuff like that. Also, my battery life was worse on 4.4.

An update is scheduled for release this week though, and it'll be a bugfix update according to Sony, so let's cross our fingers.
[Sony Xperia Z Ultra] LordManhattan:
Yeah, I read that wrong. The Z1 has three separated kernels, one for KK, one for 4.3 and one for 4.2, unless I'm reading it wrong. The Ultra has the KK version as far as I know.

Here's from the original thread.

Hi, are you trying to backup to external SD? Try to internal memory, just out of curiosity.

That's the error i got, when on stock sony 4.4. On that rom, the writting to external SD is disabled from within the phone. (not related to the kernel, I just made a test and no issue)

Install the ext sd fix, or maybe the monxdified rom?

Google it, there is even an app on the Playstore to fix this I think.

Then flash this Kernel in recovery.

Flashed in TWRP, now I can't get the phone to boot. Screen stays black, no recovery, no nothing. Any ideas? FTF time?
[Sony Xperia Z Ultra] dbolivar:
Is your bootloader unlocked? Custom kernels only work on unlocked bootloaders. If it's locked, unlock it (backup your TA partition first) and it should boot. If it's already unlocked, then it's a different issue, but you should get back where you were by just flashing the stock kernel back (putting your phone in fastboot mode). As a last resort reflash a whole stock FTF.
[Sony Xperia Z Ultra] jfsat:
My bootloader is unlocked, so it must be some other strange issue. I had a stripped FTF with just the stock kernel, so I flashed that, and I'm back in business. Do you think flashing this kernel in CWM would be better?
[Sony Xperia Z Ultra] dbolivar:
The correct procedure is to flash in CWM, since it includes some kernel modules. But even flashing just the boot.img, it should at least boot. What model is your phone? I think someone mentioned issues with the C6802.
[Sony Xperia Z Ultra] jfsat:
I've got the 6833. I'm flashing the latest "locked dual recovery" which is technically a triple recovery, and I'm thinking I'll try PhilZ.
[Sony Xperia Z Ultra] kipue:
I'm fine on 6802 so it's not a model issue.

And I have flashed using vanilla CWM :) I was running monxified rom before flashing this, if that helps to know.
[Sony Xperia Z Ultra] warfareonly:
Just tried installing the kernel on .757 via the fastboot method, and it works.

However, I would not advise using this method as DoomLord himself doesn't recommend it.
[Sony Xperia Z Ultra] blueether:
doing it this way you dont get the kernel modules included in the zip, although I guess you could always sideload/push them
