Alright sure! but as you may know, i have an unusual hot device, and on stock configurations it reaches 60 degrees really quickly. and on stock config 60 degrees is the point when the device starts to throttle, and degrade performance. But thank you, i think ill try it out! :)
[Xperia Z4/Z3+ Original Android Development] Myself5:
Sure does. Just flash systemless SuperSU (last stable is always tested with the kernel).

Performance should technically be a tad worse than other kernels, caused by the underclock. HOWEVER, due to the S810s hot nature, it wont run very long on its highest clock, and will underclock (even under our underclock limit) rather fast. So after all, you probably wouldnt see MUCH degradation especially not in real life situations, if at all you'd see them in Benchmarks. Temperature, should be way better than on stock thanks to the underclock (my Z5 is IMO cooler than my Z3 on Carbon LP and a performance optimised Kernel (M5 Kernel).

Lags: Helll naaahhh.

Stability: Using the kernel since release (that is Z5 release ofc) +1 Month. Had 3 reboots I am aware of. All while playing Pokemon Go. So, not sure if kernel or Game related at this point.

And Such: You won't see as much features in OM5Z as other competitiors provide. Thats because we focus on having a simple, basic daily usage kernel, with small and sensible additions here and there (e.g. kexec).

Hope that clears some stuff up.

Testing it !

Hi,

12hr using, so far everything works well, no boot loop, no hangs, no lag,

For those who like me are not as expert as others a resume what i did:

* Download .253 from xperifirm (Custum DE)

* Remove fwinfo file from download

* Create flashable bundle (omit all .ta files) on flashtool (Answer no to script question)

* Backup (always backup )

* Flash bundle into the phone... I didn't wipe userdata but i can be done (Answer no to script question)

* Restart into system normally

* Flash vía terminal (cmd on windows) this kernel "boot_ivy_OM5Z_253.img" --- To get fastboot mode (Hold volume + while conecting usb cable until blue led flashes)

fastboot flash boot boot_ivy_OM5Z_253.img

* Flash twrp 3.0.2 for ivy

fastboot flash recovery twrp-3.0.2-0-ivy-20160606.img

* Restart on recovery twrp ( Power on phone, pres vol+ once while orange led flashes)

* Flash newest superSu stable (2.76 at this time) vía flash zip

* Wipe caches

* Restart to check root :good:

Enjoy this awesome work ... thaks :)
[Xperia Z4/Z3+ Original Android Development] Trilliard:
Your Kernel is working really good when using it as a "user" but something is a little bit wired with this Kernel. I dont get full access to the whole System. When using TWRP it doesnt show the temperature and it doesnt show severall partitions like oem an these small ones. When Android is booted i get access to all partitions using a root explorer, but cannot access all files on all partitions. All other Kernels have no problems with this, testet all there are for our device (stock,androplus,zach´s) and om5z is the only Kernel which produces this phenomenon. Would be wonderful if you can fix this, it´s a great kernel for daily usage.
[Xperia Z4/Z3+ Original Android Development] Deleted member 4819888:
other kernels have twrp embedded in the boot.img, using rootkernel script. That one is modified to fix the cpu temp issue you mentioned, and also offers the ability to mount the other partitions.

OM5Z boots recovery from the FOTA/recovery partition, so as to try and seperate boot and recovery as much as possible. Those issues are basically recovery issues, not so much kernel issues.

About access to partitions on android, did you install supersu?
[Xperia Z4/Z3+ Original Android Development] airlessproject:
did you actually use pure stock kernel from the firmware or you used the one repacked with the rootkernel script [MENTION=4819888]oshmoun[/MENTION] mentions?

also should be noted that you can use twrp with pure stock kernel only by fastboot boot, not by fastboot flash recovery because stock doesn't have init_sony and purple keycheck light

I think he meant he has access to partitions inside the ROM, only not in recovery..

PS I had only 2% overnight drain in almost 7 hrs with wifi on and being logged in on several huge drainers like Facebook, Messenger, Viber etc.. whereas before I had always >1% per hour

That should say enough about this kernel's power savings... Simple stuff but pretty effective
[Xperia Z4/Z3+ Original Android Development] Trilliard:
I used Stock Kernel with rootkernel mod. And yes your declaration that this is related to the recovery itself makes sense. The Problem with access to some files when android is booted could also be relatet to latest systemless root (2.76) i dont know. I had access to all partitions when android was booted but not the rights to access some of the files (copy or delete files).

Well cause of the limitations of twrp which could be used with your Kernel, i cant use it for the Rom i´m actually working on, need access to all partitions hehe. Is there a way to integrate modified twrp into your Kernel?

The power savings are awsome, no other Kernel has such a good batery life.
[Xperia Z4/Z3+ Original Android Development] Myself5:
Use the boot image and run it trough rootkernel like you'd do with stock itself. You might need to change the the modules folder name to what OM5Z does display.
[Xperia Z4/Z3+ Original Android Development] airlessproject:
I think you can try repacking this kernel with rootkernel and add twrp to it, but when I tried it gave me some assertion error, so you may have to change something in the script to make it add twrp to this kernel.

Edit: Myself5 already answered this in a similar way :)

About the system files, apologies, I didn't read correctly, well it may be the supersu version, try with others and also you can try another root explorer or adb shell with su if you have a PC connection (or in Terminal Emulator), to check whether you'll have that access..
[Xperia Z4/Z3+ Original Android Development] At7ada El3alam:
first thanks for your effort

i'm new on sony phone so i don't know so much on how to root them or flash a kernal i used to do it on samsung

OM5Z-Kernel-V2.0-M-ivy_dsds.zip

tell me what i can do :D
[Xperia Z4/Z3+ Original Android Development] sinuhedl:
Hi,

If you haven't, you start at:

- Have an unlocket bootloader to perform this tasks..

- Update phone to this version of the fw .253 wich match this great kernel..

-Once that flashing it's easy,

Look at my previos post here:

[Xperia Z4/Z3+ Original Android Development] sinuhedl:
Info...

That's correct,

In order to keep some key functionality, is highly recommended to backup your TA partition, that has DRM keys to access things like improved camera processing...., before Unlock Bootloader, because this process delete it permanently.... to do this look into the forum for the guide, i give you a hint... look at this link

To UB, just follow the instructions on the sony website, it's straight forward ( careful this will do a complete clean on the phone, backup anything important to you) look at this link for this

In general use the search box, you will find almost everything you need in the forums, read the post's carefully and be sure to understand the steps before proceeding.

Cheers

Is there any sound enchantment in this kernel? I find when I turn my volume up it stops playing or switches between my headphones and phone speaker in second intervals. Only happens when I'm two click away from max volume.
[Xperia Z4/Z3+ Original Android Development] krusir:
This kernel works great for the temp reduction and normal power consumption.

We know it does not include TWRP. I know I can use "fastboot boot twrp1.img" to get into twrp directly. However, this require doing it with PC. This is how I can get SuperSu and Xposed installation done.

I tried key combination. PWR UP, push VOL+ when see LED lits. This works with other kernel which include TWRP. I got boot loop if I tried that. I have to hold PWR+both VOL+- until feel three vibs ... then I can boot it up again. I tried reflash recovery image by "fastboot flash recovery twrp1.img". Still the same results.

I can live this this since we don't get to TWRP that often. Any way to address this?

On charging complete, there is already cyan LED color. Other events depend on the particular app that causes them (e.g. Facebook notifications are blue, FB Messenger's are green and so on, some apps allow changing of this, most not)
[Xperia Z4/Z3+ Original Android Development] airlessproject:
Btw unrelated to the kernel, on .253 I had some issues with connecting, or more accurately disconnections of phone function (I was unavailable for brief periods when people called me and the phone was asleep in a spot where there is good reception)

I seem to have fixed this by flashing only the modem related firmware files (amss_fsg.sin, amss_fs_1.sin, amss_fs_2.sin and modem.sin - exclude everything else) from .224, so anyone having such problems can try this.
[Xperia Z4/Z3+ Original Android Development] :

kinda weird since modem updates are mostly to add/update providor data (I think)
[Xperia Z4/Z3+ Original Android Development] airlessproject:
I think my problem was exactly my provider :) or better said, using .253 on it

In my country, on older Sony (sometimes others too) phones folks would be unavailable for long periods and even when screen is on and full reception shown in status bar.. Operators wouldn't raise an eyebrow.. :/

My main point is, I can't complain to them cause they don't sell Z3+ and they'll just say they don't offer full support for phones they don't sell.. We're talking about T-Mobile here, not some virtual unknown operator.. So I have to fix my own stuff :)

Hey there

I flashed everything after unlocking the phone using iovyroot_v0.4 following the post by najoor

I made a backup of the TA partition and unlocked the phone. I went on by restoring the TA-partition and updating OTA to MM .253. Then I re-unlocked the phone using the key I received from the official sony site.

After that I flashed the Kernel and TWRP. Then using TWRP: SuperSU and Xposed framework.

A mistake I made which caused a bootloop, was that I flashed using the wrong commands (I know... it's should be kinda self-explanatory). So make sure you use the fastboot flash boot for the kernel and the fastboot flash recovery for the TWRP.

I can't quite remember if I used the TWRP by olivier or MotexT, but one of them works just fine.

Hope this works for you =)

and btw, please don't re-post the whole original post... it's kinda annoying to scroll through it... just use an @ sign if you want to mention somebody...
