Volte status: I am closer to resolving this. I think this has to do with camera.

Indian Jio users should try this: flash June 9 release, but before rebooting, delete camera app in TWRP; then reboot and check volte after another reboot. Also, on first boot, when volte works, make one call and then reboot.

Camera permission is needed for ViLTE which [MENTION=5075064]optimumpro[/MENTION] was trying to fix.. Volte only stopped working when he tried to fix ViLTE.. So I guess that's why VoLTE is not working and somewhat related to camera like he said..

@optimumpro i really liked your hotplug implementation.

Earlier i was trying to configure autosmp for my use - which i did and cores were shutting off after 3 second delay so that i dont feel performance hiccups.

But your implementation is really great. A lot can be achieved with a perfect hotplug with performance profile.

I´ve solved the issue by reinstalling the ROM clean! Not sure what caused this, but everything is fine now and the folder stays upon reboots. Odd...
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] optimumpro:
Another point about security:

Starting with Nougat, Google has changed the way blobs are accessed, namely, blobs located in system cannot be executed by 3rd party apps. Blobs in vendor and other partitions could be. In treble roms, there is a separate vendor partition, and the recent tendency has been: to move as many blobs as possible to vendor, where they are open to all apps. Why? Let's keep it in one place. This coupled with ro.secure=0 is a recipe for disaster.

[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] Andro Enthusiast:
Dear Developer !

I highly value your work for our device and you are the one who responds to majority of user queries and doubts in XDA and implement features requested by users more often. Thanks for your work !

But I feel the above statement of yours is kind of misleading (based on very little knowledge of mine in Android).

The core concept of Treble lies in the fact that a separate vendor partition is created and all the device specific blobs are placed in that partition and this helps in faster updates once aosp sources are available for forthcoming android releases.

Developers don't have the need to do a lot of work to change things in ROMs which are related to specific devices as they are all present in vendor partition.

This is what google has brought in Treble and the Treble ROM developers just follow that principle and work on it.

And regarding ro.secure part, my understanding is that one can gain root access through adb with it set to 0. If you mention it as a bug and for this bug to be exploited, one needs physical access to the device.

Yes, it is better to have it set to 1. But its not a big security risk to have it set to 0 also. I doubt if the installed apps has anything to do with it.

Dev. I am not against you nor I am a fanboy to any particular dev. I respect all the devs who work to make our device better. Just posting what I felt.

Thanks again for your work :)
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] optimumpro:
I have no problem with your post, but you are wrong: ro.adb.secure is for adb; ro.secure is for system. Having ro.secure=0 makes system fully writeable without any prompt. Even for sd card access you get a prompt for permission on first use. Having system open for writing is the ultimate goal of virtually every exploit. In secure roms, they must hijack an app or process that can write to system. In roms with ro.secure=0, your device is already wide open.

Also, project treble is not about the location of the blobs, but rather about a new interface (hidl) that allows newer android frameworks to communicate with hardware. In other words, blobs could still be in system/vendor, as opposed to a separate vendor partition.

Project treble has a future, but the way it is done in our device makes it wide open for any exploit. It is like having a house with a hole, instead of a door.
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] optimumpro:
Are you sure? Because others are saying that volte stops working after reboot.

Nothing, other than your system becomes inaccessible without a special permission. The irony is: you just need a 'ro.secure=1' entry in build.prop.

With treble, it is different, because you need an additional permission interface, which is broken in our Zuk.

@ optimumpro. The notification text not being visible still exists in themes.

But the main problem I faced is on installing the latest kernel, the phone didn't boot up and It was stuck with boot animation..

Tried clean install, but phone refuses to boot.

This problem is occurring only on installation of new kernel.
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] optimumpro:
Notification text - already discussed. Longpress that notification in QS, and when you get to additional settings, set importance level to medium.

Kernel: have you unzipped the file? If yes and still no boot, then maybe this is because kernel was built with another release, which hasn't been posted yet. But I think other users were able to boot fine.

Just plz tell me this I can't wait to install !
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] Elton889:
well this is series of event that happen if you flash jaguar oreo zip and gapps

1st you will get stuck in boot logo, wait for a min or 2 then force restart.

Next time it will boot up quickly to google setup in which you select restore through cloud backup.

Finally at the end of setup you will get stuck again at "adding final touches", just force restart and do

the setup again where it exit properly.

Then you reboot to recovery and flash magisk(for root).

this method worked for me, till now no issues for me.

One reboot and volte gone again. The new zip is working just the same as other recent updates with no stable volte. Tried disabling camera but didn't help. Please elaborate ur concern.

Clean flash and report. It is some settings issue.take titanium/nandroid backup and clean flash

The stock kernel is fine. Use akt profiles in the settings section, under which u can chose project xana or jaguar battery both are great battery savers with basic performance. If u want more battery than under clock cores to 1Ghz. 6hrs + sot is considered great

Latest build quick review -

ROCK SOLID STABLE.

Rom is butter smooth. This one is actually smoother than recently ported oxygen os ( no offense to anyone - i understand how much pain and hard work it is to do this for free)

AKT has been implemented flawlessly ( i will love to see some new profiles created by one and only optimumpro).

For now i stay on jaguar performance for most of the time.

I have created three basic profiles in kernel auditor clean.

OC, no oc, and 1ghz ( thanks to guyz_ahead for underckocking suggestion). So basically i only changed pu maximum in these profiles. Reason i have created these is that I want to switch cpu clocks with a widget.

Oc-2.3ghz and 1.766ghz

No oc- 2.1 and 1.59

1ghz - both little and big max set to 1036 mhz.

I use combo of akt profile and these ka profiles. I stay on jaguar performance profile along with 1ghz constraint for day to day scrolling and have not faced any lags whatsoever.

I use ghostpepper along with oc or no oc while gaming.

Fairpark along with 1ghz for extreme saving situations.

All these with optimumpro's active hotplug stands out really well on our sd 820. I am able to juice out 6-7 hours while maintaining jaguar level performance. I don't want more SOT. Literally how much more will anyone look into a 5 inch screen in one day, there is more to the world around us.

Camera is working for me - no delay.

If you've problems accessing your camera try enabling/disabling camera hal hdr+ setting in developer settings and reboot.

Heat management is same as previous builds.

My advise would be use intellithermal when using for day to day operations and turn on core control when you play pubg or any other heavy game.

I am not a Jio user ( rather airtel one) so am logically not concerned about volte and vilte. But i do realise that for people out there, volte is the only way to use their device to be able to make calls so it is pretty must for them. I believe dev will cater to them too ( as you see he is trying hard already).

All in all kudos to optimumpro. I am forced to return to his awesome work again and again.

PS : i would really love to see some more of your created interactive profiles [MENTION=5075064]optimumpro[/MENTION]. Cheers mate

[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] Andro Enthusiast:
Dear dev,

1. Regarding ro.secure part,

"ADB allows a PC or a Mac to connect to an Android device and perform certain operations. One such operation is to launch a simple shell on the device, using the command adb shell. The real question is what user do the commands executed by that shell process run as. It turns out that it depends on the value of an Android system property, named ro.secure. (You can view the value of this property by typing getprop ro.secure either through an ADB shell or on a terminal emulator on the device.) If ro.secure=0, an ADB shell will run commands as the root user on the device. But if ro.secure=1, an ADB shell will run commands as an unprivileged user on the device. Guess what ro.secure is set to on almost every stock OEM Android build. But can we change the value of ro.secure on a system? The answer is no, as implied by the ro in the name of the property. The value of this property is set at boot time from the default.prop file in the root directory. The contents of the root directory are essentially copied from a partition in the internal storage on boot, but you cannot write to the partition if you are not already root. In other words, this property denies root access via ADB, and the only way you could change it is by gaining root access in the first place. Thus, it is secure."

https://seasonofcode.com/posts/how-...planation-of-the-android-rooting-process.html

"ro.secure=0 will result in adbd running as root by default"

https://bclary.com/blog/2014/04/14/splitting-and-packing-android-boot-images/

The above articles also say after gaining root access through this way, one can mount system as read/write. And for this to happen, one needs physical access to the phone as I mentioned in my previous post. I don't see anywhere being this related to apps accessing system and exploiting it.

2. Regarding vendor partition in treble part,

Yes, blobs can be stored in system partition. But as per my understanding of the below linked article, GSIs can't be flashed in those types of trebled phones.
