[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] dwellexity:
Follow the installation instructions of r13 for people installing jaguar for the first time (even if you are on jaguar). You will have a clean installed ROM.

Here are the instructions as quoted from optimumpro's post.

August 12. Release 13:

1. August Security Patches

2. New Camera driver and blobs

3. EAS in kernel

4. Voltage control for CPU cores

5. More columns and rows in QS

6. All network choices in Cellular menu (like in testing) and your selection will hold

This build includes experimental EAS implementation in kernel, which needs adjustment. So, to have the best performance, do this in Kernel Adiutor:

1. Increase (+) overall CPU core voltages by 15 mv

2. Switch to Nightmare or Impulse (my choice) governor for Big and Little

3. Use Noop scheduler

Or if you don't want to deal with EAS, just flash the standard one without EAS and with updated camera driver: download link just above

Instructions:

if you are on r12.1, just flash dirty; flash Gapps; reboot and then Flash Magisk: that's all you need;

If you are coming fresh, you need to do this: AND THIS IS A REVISED PROCEDURE TO MAKE IT EASIER - You don't even need to deal with Gapps or Webview in release 11

1. Wipe system/data/cache/dalvik) and flash r11; reboot and let system run for a couple of minues; then back to TWRP and save Jaguar data (data only, untick everything else).

2. Clean flash r13 (again wiping system/data/cache/dalvik); restore saved in TWRP data (again data only), flash Gapps and reboot. If you use Magisk, then back to TWRP and flash Magisk

That's all

Maybe he knows that procedure but he is asking for standalone zip that can flashed once and that's it it's much more simpler than the existing procedure

how to delete crashdod???
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] the.D:
How to recreate this unexpected behavior:

First, connect USB and access the Developer options by tapping the "USB debugging connected" notification. Next, turn the Developer options off and exit the menu. Finally, reactivate it by becoming a developer through the Build number trick. At this point your device will never appear for the ADB server.
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] pipyakas:

Also, do you plan on keeping EAS, or would you rather revert everything back to normal? star_king12 still improving his EAS implementation with AEX

Guys why do you compare others ROMs here in the first place, this thread is for problems and solutions to Jaguar. Why fight other ROMs are better than this here? Please come to your senses and not hurt developers.
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] the.D:
Just clean flash Jaguar and don't turn off Developer options...

[MENTION=5075064]optimumpro[/MENTION] As a security focused ROM could we have USB debugging disabled by default in future releases?
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] optimumpro:
That's because you don't read instructions or can't comprehend them. But luckily, there are plenty of roms here. So, be a guest and use them. No one is forcing you to flash or use Jaguar. And watch your language. It is your use of it, which is disgusting...

Cheers...
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] Deva Kaushik:
This ROM focuses on Speed and Security. Updates will be monthly. That is what actually quoted by the developer several times, may be it has less customization but works very well for me and others who are using it.

Coming to the procedure it may be difficult but if anyone asked for clarification the developer here never failed to respond which I would like to appreciate anytime. Especially when we face problems while flashing we get to learn more about it (that's how I learnt at least).

For me a ROM with speed and security is always the best, for others like you it may not so go use other ROMs. Its no use fighting for someone here and disturbing new guys who are finding solutions to Jaguar here.
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] optimumpro:
F2fs is not supported. Read XDA interview with Franco, who knows more than a few things about kernels and OS. He is saying the same thing as me: there is no proof that f2fs is any better than ext4. But there is a lot of proof that f2fs is inferior in stability. It has taken 20 years (and continuing) to make ext4 shine. Plus, the only ones who know about file systems are Micrsoft, Linux and a few others, but certainly not Samsung. You can have good hardware, but that doesn't make you an expert in file systems.

Will do...

Will converting data,cache to ext4 work?
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] sotosgolf:
Yes, the flash was successful. While i was flashing, the charging symbol disappeared in TWRP. The phone eventually started charging in TWRP 5-10 minutes after i wiped everything. I will definitely avoid flash while Charging in the future.

[MENTION=5075064]optimumpro[/MENTION] i flashed r11.1 and i don't have internet. I searched for crashdod.sh in /system/etc but it's not there. Am I doing something wrong?
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] Mr. Clown:
Ok, I just cleaned tons and tons of unnecessary drama and bickering.

Everybody should use that energy towards development. If someone is not happy with the ROM -just don't flash it and move on. If anyone has a problem with the OP for not complying with XDA rules - report him (that goes for the OP as well, to report any user when off topic and derailing of this thread).

There is constructive criticism toward development and I think any developer on this site is completely open to it, for the sake of improving development experience. However, disrespect and insults will not be tolerated on XDA grounds coming from anyone.

Back on topic please, I don't want to come back here and deal with this nonsense again.
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] optimumpro:
Well, if by converting you mean formatting data and cache as ext4, that would work. But really preserving files? You really don't need that, especially if you are coming from a different rom: data partition from another rom is not really useful.

It is in /system/etc/. You need to enable show hidden files, but you really don't need the internet on r11: just flash it, boot and save data after a few minutes. That's all. Then clean flash r13; restore data; flash Gapps and you are done. If you want root, just flash Magisk or Supersu, but after one reboot.

So even with EAS reverted it's still recommended to use impulse governor and noop scheduler?

Not a requirement, but I do use both and I like them...
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] pipyakas:
Do you plan on using them as default kernel options? Im a fan of "if it's recommended it should be default"

Same goes for intellithermal as default, also that -15mv undervolt currently in used as well
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] optimumpro:
Not sure about this. Interactive is a pretty good default governor. But you can choose impulse and other options in Kernel Adiutor. Undervoltage: I never recommended -15mv on standard kernel. Only +15mv on EAS version. In fact, when I tried global -15mv on non-EAS kernel, I got random reboot, as soon as the phone went to deep sleep, which means not enough juice on lower frequencies . So, what I do now is reduce current voltage by -15mv on 2 top frequencies and it works. But Z2s have different CPU variants and what works for mine may not work for you...
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] luws:
Is intellithermal recommended? Should I turn it on and The other options off?

My opinion is that it's good in one way that USB Debugging is on by default. It helps if we get into boktloop or for the people who flash without reading the instructions. It actually helped me once. :)

Try Open Camera.

Rootless OMS isn't coming. You know why it is called rootless? Because it has total root rights without notifying the user. In order to accomodate "rootless" oms, developers must force authorise all substratum packages in frameworks, which they all do: I call it headless copy & paste. So, if you have rootless substratum package, you have mother of all Trojan horse: it has total root that can't be controlled by Magisk or Supersu; it has unlimited internet access; and it compiles on device, which means the theme can inject whatever it wants. In my view, anyone who would continue to use rootless oms after knowing the above, should be in school together with rocks (dumber than a rock).

So, you pay money for these? I was right. I have had a horrible experience with some of the devs, when it was Layers. As*holes, especially themers, who usually know very little about development. All of them went to Substratum and now, they are writing commits that go to frameworks, which is the center of Android. Those commits go around Android security for substratum to work. In Layers, the changes were only to color exposures. In substratum your device's security has a huge hole. Think about it, which other operating system allows an app to change and compile internals of your OS? None. Forget about smart phones: think Windows, Apple, Linux? None. And there is a good reason for it. And why do you think substratum is done this way? Money! I don't mind people getting money for their work, but to compromise device security?! Pure (and stupid) As*holes!!!

If it was up to me, I would have banned the entire substratum development from XDA forever...

[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] optimumpro:
I have looked at the source. The module is pretty good. You would need terminal to pick options and you need to be careful, especially with the options: 'interpret-only' and 'verify none'. Anyway, the difference you might notice is in milliseconds. When this module's dev talks about compilation, he means runtime compilation: things the system does during boot to get the apps ready. Once the apps are 'compiled', there is no difference in speed.

I can't agree with you more. That's one of reasons why I got interests in your rom.

I spent a few $ for themes for other rom, realize that making themes is easy and some devs is charging more than they should for probably “design” which is often just changing colors.

In general, I use this smartphone for a limited use, no sns, no game, etc, and my main phone is iPhone. My concern may be only about Google and Apple.

You may be able to put a simple theme changer like “light-dark” in, but necessary, and I would be happy to keep your rom as long as I own Z2.

First of all, thank you for your magnificent ROM. I would like to report you a bug: this is, I use 2G, when I reboot the smartphone the network does not change to 2G, it stays in 3G. It is only changed when I go back again to the network configuration (without touching anything), it automatically reconnects to the 2G network. I could see it on the information of the SIM, from "About Phone" that stayed in HSPA + if it did not go back to the configuration of the network. You can check it for yourself. Thank you. I expect some response from you.
