[Sony Xperia Z Ultra] FiWi:
If you have the non GPE edition of the Z Ultra, use the regular Doomlord kernel. The GPE won't work for our version. I tried using it and the phone wouldn't boot.
[Sony Xperia Z Ultra] blueether:
I thought on 4.4.3 the GPe kernel was working? I didn't run the 4.4.3 version from here. I did have 4.4.3 GPe ROM that I was goint to release running on the GPe doomkernel - although it was unstable, but it was unstable on the stock kernel as well.
[Sony Xperia Z Ultra] FiWi:
I'm not sure about 4.4.3 because I never used that version, but for the 4.4.4 GPE port DoomLord v20 works flawlessly.
[Sony Xperia Z Ultra] ywliu:
Yeah. I have the same experience. It was said in 4.4.3 thread that the auto focus may be the problem.

Not every C6802 has this issue. Maybe just a tiny hardware difference varied among phones. I am stick to 4.4.2.

[Sony Xperia Z Ultra] Tundraswan:
Should I be worried that in "About phone" it shows "C6806" as the "Model"? This won't screw with my LTE/4G use (not in 4G area so can't test yet..)?

The only small problem I'm having so far is that wifi tethering stops working after a few hours, it still shows as active and running on the Z Ultra, but the devices that were connected to it cannot see the AndroidAP wifi network anymore... Anyone else seen/has this? Any fix? Could switching to DoomLord fix this?

EAP-SIM

Can anyone confirm if EAP-SIM is available as a Wi-Fi security method, in the GPe port? In stock ROMs, it is. To check:

1) Open Settings, and go to Wi-Fi.

2) Click the option to add a network.

3) Under Security, 802.1x EAP should be listed. Select it.

4) Under EAP method, you should see SIM as an option.

Thanks!

I have non GPE version of C6833 and Doomlord kernel modified by scrubber worked well on it, after I flashed scrubber 4.4.3 GPE ROM.

However, this kernel doesn't work well (unstable) with scrubber new GPE 4.4.4. ROM, as well as it doesn't work with scruber 4.4.4 InitD kernel (TWRP works but CWM doesn't). I returned to GPE 4.4.3 ROM.
[Sony Xperia Z Ultra] mcteague:
Hi guys does this ROM use GEL launcher now that its on 4.4.4.
[Sony Xperia Z Ultra] jutley:
i just did a dirty flash over the 4.4.3 rom via recovery and it worked fine no factory reset the only thing i had to reinstall was my xposed framework.

Flashed this rom with doomkernel and enabled ART. Oh lord. My phone runs faster than a koenigsegg :eek:

Sorry for the noob-ness of this question, But I just got my xperia z ultra, its currently on firmware 14.1b.2.257. i've successfully rooted it, an unlocked the bootloader, but I seen in the requirements you have to be running firmware 4.4.4? im confused I thought it didnt matter since your flashing a new firmware.. what all do I need to do from this point?
[Sony Xperia Z Ultra] SUPERUSER:
You need to flash stock .108 first before flashing this rom. Its because of the radio being upgraded all the time I think. If you don't flash .108 you not getting any radio to start.

I will put this in a hidden box so my post isn't that long

If you need help to learn how to use flashtool I would suggest reading the guides

http://xdaforums.com/showthread.php?p=45187944

When you done flashing the stock rom in the link above boot the phone up and move this rom .zip file found in OP post to the sdcard then you can reboot to recovery and flash this rom

But before you start you have to flash doomkernel just to install a recovery so you are able to flash this rom.

[Sony Xperia Z Ultra] mistororange:
okay so I need to use flashtool/quickimg, to flash the doomkernal, then after that I need to flash a custom recovery? and then I need to flash the stock rom you linked, an then from there I flash this one? ha.. man this has got to be the most complicated device I've purchased to root an install roms on :_D also I noticed this part on dooms kernal "newer kernels wont boot on older stock ROM or ROMs based on older FW, you will get bootloops!" does this apply to me? lol thanks for the help

[Sony Xperia Z Ultra] curiouso9:
Waiting for doomlord kernel to be compatible, now sticking with 4.4.3
[Sony Xperia Z Ultra] E90 Commie:
I use DoomKernel v20 with this ROM and it works perfectly.

Regarding baseband: I didn't flash .108 before I went from 4.4.3 to 4.4.4 and everything works. I am on the .757 C6802 baseband now and I haven't seen a FTF with the newer ones (I am not going to flash a C6833 bb to my C6802).

Everything seems great so far with this version of DoomKernel even if it will be great when the 4.4.4 v21 arrives.

Edit: This ROM provides great battery life with DoomKernel v20 and intelliactive on all four cores: 1% battery consumed in... 4 hours. I am using Greenify and DS Battery Saver as well but I consider it really great still.

I also used slight UV, around 25 mA for each frequency step.
[Sony Xperia Z Ultra] dimex:
I'm a little confused. What does this mean in the instructions?

I'm currently on the 4.4.4 Sony .108 at the top of the Android Development page, but I want to give this a shot.
[Sony Xperia Z Ultra] iBuzman:
it probably should say "fastboot flash boot boot.img w/ cmd prompt / adb" seeing you are asking about this I suggest you google "quikimg" and use that (save you setting up ADB environment)
[Sony Xperia Z Ultra] dimex:
I have and understand how to use fastboot and adb. If you could please forgo the "you're stupid, look this up" jargon, I'm just wondering, do I extract just the boot.img from any CM ROM and flash that first? If I already am on .108 with TWRP can I just wipe and flash?

Just a quick set of instructions and explanation would be great. Feel free to PM me if you don't want this discussion to clutter the thread.

Thanks for your help.
[Sony Xperia Z Ultra] iBuzman:
deleted for being an unhelpful clown.. (evidence below) sry mate, crashed my database at work whilst answering posts and took it out on you..
[Sony Xperia Z Ultra] dimex:
Wow, you're just great.
[Sony Xperia Z Ultra] blueether:
It means what it says. fastboot flash a boot image with recovery (if you dont have one that will flash the rom)
[Sony Xperia Z Ultra] dimex:
Thanks blueether for answering. But I'm confused with where you get this boot.img; from a kernel?

So basically grab a kernel with recovery, extract the boot.img, flash that, then go into recovery and install the ROM?

I've just never done it this way, always used Flashtool with my ZU. If I'm already on rooted .108, can I just go into TWRP, wipe and flash?
[Sony Xperia Z Ultra] iBuzman:
^^ (post edited above) you need to flash kernel for this to work, if you just flash rom without doing this first you won't boot due to stock kernel still present.
[Sony Xperia Z Ultra] dimex:
So how about installing [NUT]'s ZU dual recovery through install.bat method with phone plugged in? That would be a working alternative?
[Sony Xperia Z Ultra] blueether:
nononononono

the post above your first one says they are using doomkernel - why not try that one

I may hav mislead you slightly I should have written "fastboot flash a boot image with recovery (if you dont have one that will flash and boot the rom)"
[Sony Xperia Z Ultra] maxld:
Guys, I am very tempted to install this ROM. Question is: how is real battery life? Much worse then stock?
[Sony Xperia Z Ultra] Jayz2K:
Just for information since there was no feedback ... This did not solve my camera problem. Autofocus still frozen. 4.4.2 backup restored.
[Sony Xperia Z Ultra] boyz1984:
Anyone have camera issues with native camera app? or the third party camera app?
[Sony Xperia Z Ultra] E90 Commie:
This ROM has excellent battery life with DoomKernel v20 and intelliactive governor. I lost 1% during five hours of sleep with WiFi on, i.e. a consumption of 0.2% per hour.

During use, I loose 1% every 7 minutes (took careful notice yesterday), approximately 8.5-10% during one hour with screen on, browsing the Internet.

I am also using Greenify and DS Battery Saver as replacements for Stamina Mode. Since I flashed the first 4.4.2 GPe ROM, I have not looked back to stock for a second. When I noticed that the notifications disappear with 240 DPI on stock ROM (4.4.2), I gave up on them completely.

You can use Sony apps on GPe such as Album, Movies, Notes, Sketch, Walkman and so on - and you have ClearAudio on this ROM since Sony included it as a small extra when they created the Z Ultra GPe.

In fact, I don't see any reason to stay with a Sony ROM any more, this ROM is simply superior and let you keep all great Sony additions through ported apps without having the bloat. It gives you the best of both worlds.

So go ahead and flash.:good:
[Sony Xperia Z Ultra] dimex:
Awesome ROM. No force closes and camera works perfectly with DoomKernel v20.

Is there any way to get the small apps from Sony on this?
[Sony Xperia Z Ultra] Leechoonhwee:
The only reason I need to use stock rom is because the camera doesn't work on GPE for me. It used to work great on 4.4.2 but somehow 4.4.3 broke something and it's not working after that.
[Sony Xperia Z Ultra] hudsonhicks:
I had same problem.. massive lag with camera however last night i tried flashing doomkernel + this GPE and camera works great.
[Sony Xperia Z Ultra] dimex:
Anyone else notice a slight delay when initiating programs with ART enabled? It's like a minor lag, not bad but nnoticeable.

ART is indeed much snappier though, really nice.
[Sony Xperia Z Ultra] LordManhattan:
No issues like that here. ART is running like a king here, and all the micro lag is gone. It's easy to tell the difference between Dalvik and ART (for me at least).

Dalvik = You'll get some micro lag when you scroll etc.

ART = All (99%) micro lag is gone
[Sony Xperia Z Ultra] crodgers79:
Where can I find the default Sony Apps in a flash-able zip file?

Thanks for the insight.. do you know where I can find the default ZU Sony apps in a flash-able zip file??

Chris R.
[Sony Xperia Z Ultra] E90 Commie:
Sony apps can be found in both Android Apps and Games and the Cross-device development projects for Sony devices.

Most of them are regular .apk even if some of them are available as flash-able zips. I use the apk versions, though.

Album, Movies, Sketch, Podcast and Walkman etc works. The same applies to the Sony Alarm/Clock and so forth. Even Sony launchers are ported but I don't see the point of using them when there are better ones like Apex, Nova or ActionLauncher available.

There has been an "Advanced Xperia Launcher" with adjustable grid sizes etc as well but the development seems to have stopped last year (it was based on the Z launcher).
[Sony Xperia Z Ultra] zost:
I tried to switch to ART. I checked "Use ART" in Developer options, but after reboot my C6833 is still on "Use Dalvik". Do I miss something?
[Sony Xperia Z Ultra] maxld:
Do you use xposed? If yes, then uninstall it, because it is incompatible.
[Sony Xperia Z Ultra] LordManhattan:
Remember to not simply uninstall it like a regular app, but uninstall it by using the uninstall button in Xposed. It took me a while before I figured this out.
[Sony Xperia Z Ultra] adfurgerson:
Im guessing the app could stay as long as framework is uninstalled.
[Sony Xperia Z Ultra] LordManhattan:
I believe that's the case, yes.
[Sony Xperia Z Ultra] zost:
Many thanks for your reply. I will try without xposed, but I think that ART will wait until next version of xposed and its compatibility with ART. ):
[Sony Xperia Z Ultra] iBuzman:
^^ art compatible xposed not until android L then only maybe (sry OT)
[Sony Xperia Z Ultra] dimex:
haha I was under the assumption I was using ART this whole time and raving at the speed, yet, xposed kept me on Dalvik.

I'm like the guy who says "omg I'm soo wasted" after drinking a 12 pack of non-alcoholic beer.

Oh, also, is anyone using the optimized Dalvik/Bionic libraries? Notice a difference? I'm afraid to flash, this ROM is perfect and hasn't forced closed a single thing yet :P.
[Sony Xperia Z Ultra] E90 Commie:
I flashed those libraries and the initial impression is a noticeable performance boost and smoother operation. No FCs or anything abnormal noted.

It seems like ART won't be really interesting before L is out of the beta stage.
[Sony Xperia Z Ultra] blueether:
Be carefull about flashing those libs. Both [MENTION=655433]LordManhattan[/MENTION] and I have locked up the ZU with them. Do a search for them in the ZU section as I posted a comparison of benchmarks. If I remember correctly there is now very little difference in them to stock Sony libs - ie I think sony are using optimised libs
[Sony Xperia Z Ultra] dimex:
Same here. Antutu benchmark from old libs was 28,905. Immediately following flash it was 33,623; interesting. I'll take it! Let's see if I can notice any real world gains.

So far so good after flashing them. No FCs or bootloops here. I find it so strange that, while our phones were most likely made in the same factory and house the same components, mine seems to take the updated libs fine while yours is almost rendered dead. Doesn't make sense to me :silly:
[Sony Xperia Z Ultra] blueether:
Probably older libs and older firmware.

I cant remember the exact combination of libs that did it but I was playing with bionic and another one at the same time

[Sony Xperia Z Ultra] pTeronaut:
If your phone has the word 'xperia" on the bottom of the rear face, and you have unlocked your bootloader, flash away. You might have to fastboot flash the boot.img in the zip file.

If you don't have the word 'xperia' on your phone, then you have a bona-fide Google Play Experience device and will need to update via the ROM itself.
