All the "design for nand storage", "better performance" etc... hype just keeps on coming. My z2 suffered tons of freeze, lag and generally stability issues with f2fs on /data, but had it on /cache all the time without major issues. Benchmarks result do say there are no performance benefits with sequential speed, but I personally dont know about latency, response time or random r/w performance so people can still throw hype at me about f2fs

AKT as a seperate app eats up to 100mb of ram, and stay in the background as well, which Im not a fan of. AKT also doesnt scale well with the OC frequencies that ZUK made for the phone. If anything, I want to know your view on Energy Aware Scheduling (EAS) - one balanced all-roundner is generally more suitable for most users.

Finding functions is not big of an issue when you can search in the settings app now, but the number of features that I want is rather limited, and jaguar provided most of them so far (aside from those I mentioned that are missing)
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] optimumpro:
EAS is promising, but still experimental.

And by the way next releases could be flashed on top of r12 or each other without any additional steps (except for Gapps and Magisk). If you jump to another rom, just save Jaguar data. This way, if you come back, you could easily restore it...

[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] optimumpro:
You have been using Jaguar for a while and you didn't have any unusual battery drain before. So, if you didn't jump to other roms, then trace back what you did with settings or which new app was recently installed and you will find the cause.

If the problem is root, you must actually hide it in Magisk...

It is not the procedure to follow. You should read the OP before flashing a rom it is 5min to avoid having to take an hour to solve the problems

After a day of using the phone I want to add something to the "wishlist":

- A button to toggle auto brightness next to the brightness slider in the notification panel would be nice. Why? Because fine tuning the brightness near the minimum is very difficult for this phone

- Holding power button when screen is off to turn on torch (because why not?)

- Default cpu scaling is "okay", performance in games is fine but in ppsspp is below average by a long shot. The phone doesnt heat up much and no serious battery drain overnight

Should I mount /firmware in TWRP before flashing??
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] optimumpro:
The point is: you need to save data partition while on r11 and then restore that data on 12.1.
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] optimumpro:
You don't need any extra steps that are not included in instrucrions.
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] optimumpro:
It is not tuning brightness in of itself, but rather that going down below a certain minimum is not allowed: tuning will stop at 13%.

Default cpu scaling/performance: that's why you have additional settings/options in Kernel Adiutor.

Well I got that working now the problem is Chrome and Facebook app are crashing on particular instances.

Facebook app is crashing while long pressing the like button for reaction.

Chrome is crashing whenever i open any link. The loading bar simply reaches ¼ and then app crashes. Gmail also crashes. I have Android webview installed (from playstore) but having app crashes.

On r12.1 now.

Edit: Got everything working after installing Chrome beta. Chrome stable app wouldn't let you chose the aosp webview. Now using Chrome beta with aosp webview. Not yet checked Facebook app.
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] greatcoder:
You should try the following steps:

1) First clean and install the r11 and then in the TWRP backup the data partition.

2) Then do a clean install of r12. Restore the data partition which you saved earlier.

I think this should solve your issues. I followed above steps and I did not face any issue.

Hope it helps.

Lenovo Z2 plus is a great phone but most of the people on amazon dont seem to like it

The rating is 3.3/5

They hav issue with faulty product n battery backup that sucks (they say) They also think its worst product

I belive the spec are very high as per the price

Its like 12k Rupees (60% less the MRP)

The amazon has also provided 1 extra year warranty (from Lenovo's service center probably)

So total 2 year warranty

Just..

Its hard to believe as The phones spec are really high and 2 year warranty (technical only) just for around 12k Rupees

Should i consider buying it ?
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] greatcoder:
You should go for it if you would be installing custom ROM on it. The stock ROM is very bad. I bought it for 11k. It is definitely a total value for money. However if you would install custom ROM you would need to unlock the boot loader and this would void lenovo warranty. I bought this phone knowing beforehand that I would install a custom ROM and unlocked it on day 1 itself.

Hope it helps. Please let me know if you have more queries.
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] Danny94:
Im sorry asking again, but the only one important thing missing for me in this rom - because it's samsung exclusive is a way to optimize games.

Would there be a way to port samsungs game tuner incl service on our phone ? This would improve gaming a lot (overheating, high battery drain etc) for bad developed games like pogo and other.

Edit: Game tuner allows you to change for every game:

- resolution

- texture quality

- framerate
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] optimumpro:
It may not be possible, as the app hooks to framework...

/system/app/webview. But you will have to do it every time you upgrade. Also, in developers settings you can choose between Google and AOSP webview...

I don't know much about that stuff, but would it be a lot of work to implement some selfmade small setting to change resolution, texture details, framerate values for each app ?

[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] optimumpro:

Copy rom and gapps and other needed files as mentioned to internal storage and wipe except internal storage in recovery before installing. (dont wipe internal storage)

Read previous posts as some extra steps needed before installing latest rom.
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] optimumpro:
I don't. Any app I need I get either from F-Droid or Apkmirror, which has almost everything that Playstore does.. And guess what: I have over 8 hours of SOT with wifi/data/email syncing 24/7. Plus, all that SOT time is on a web browser. So, if I had just the screen on without any other activity, I would probably have close to 10 hours...

Follow the following steps if you want to install the latest version r12.1:

1) Download r11 ROM zip file.

2) Download r12.1 ROM zip file.

3) wipe dalvik, cache, data partitions. DO NOT wipe the internal storage partition.

4) Install r11 first and take backup of data partition.

5) Now clean install r12.1 and restore the data partition you backed up in step 4.

Hope it will help you!!

Using 12.1, follows the instruction to install it and all is great no issue, except one:

** Accessibility Settings bug **

My LastPass does not work. I can open the LastPass app, but it needs Accessibility settings so it can fill in username/password on other apps.

Installed Google Chrome and enable accessibility settings for LastPass. Then open Chrome and start browsing, immediately force close for Chrome. I tried to use Google Webview and Chrome Stable in Webview Implementation (Dev mode), both does not work, always crash. But if I disable the accessibility settings for LastPass, browsing via Chrome is fine.

Trying another browser (Firefox Focus) also result in the same thing.

So I disabled accessibility settings for LastPass.

Here's the kicker. So I am using Nova Launcher, and I notice that there also accessibility settings for Nova Launcher, I enabled that, and the Chrome also got force closed whenever I start browsing.

The same thing also happened with Firefox Focus.

So it seems there might be some issue with Accessibility Settings.

I came from other ROM and it was fine.
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] optimumpro:
What are you doing anyway in Accessibility settings. Other than Wakelock blocker, there is nothing there to play with.

Other users noted that Chrome beta works fine. I use Fennec firefox and I really don't remember when I had any f/c last time...

Well, accessibility is a requirement for many apps. Hope the issue is solved with the FCs... I myself had such issues. Now I didn't install last pass till now(otherwise I also use it). It is one of the important apps I use.

Great ROM though by the way. AEX used to heat significantly while watching even videos in Facebook... And the things that are in place for security it's pretty much awesome too.

---------- Post added at 01:55 AM ---------- Previous post was at 01:43 AM ----------

Now I understand why Facebook fc occurs when I long press the like button for reactions and gmail also FCs! There's nothing wrong with my procedure for flashing. It's the accessibility bug.

Your logcat shows a crash for terminal app by jackpal, which hasn't been updated since 2015. Get rid of it, as it probably causing problems with accessibility service.

First, you need to reboot the phone to have more free ram. Second, kill non-essential apps by using kill button. Disable any power saving feature. Disable data, wifi, bluetooth, gps and even radio. Don't charge the phone, while doing the test.

Hey [MENTION=5075064]optimumpro[/MENTION] or someone please help me

After installation , just in 1 hour

These are the things I've noticed

1.I'm noticing small glitches here and there like opening any app ,it give some glitch like some sort of little hang of animation?(As far as I can explain)

I've seen this on both animation speeds of 0.5,0,and 1.0 speeds

3. Multitasking seems to be okeyish

Like eg. I've opened play store and switched to another app, play store clears off from the memory, I've not installed any battery saver or using it

2.Also, Are there any settings to edit number of tiles and Add auto brightness icon to the brightness adjustment bar?

3.And in theme engine,swift black theme is not working, it applies reboots and nothing applies

I tried pure z theme,Everything applied but Navy. Bar icons are not changing!

3.Are there any settings for lock screen settings like to customise quick pull setting/apps on bottom most corners, Change the font of clock, show charging info. Or quick kill app with back soft nav. Button?

Idk what's going on?

4.Sound output is too low as compared to aex rom 4.4(still don't know why it is so, is it me only or all user has this problem)?

5.Don't you think there are less extra customization settings in this jaguar ROM ,like add one on aex 4.4 and various customisations on rr(I know most of them are never used but ...... You may have your reasons to not to add them) neither I'm scolding you nor I'm pointing your work, it is possible that I might not be able to find these settings

If they are not present , please it is a humble request , in next update, please add some type of additional settings if possible

I've installed this ROM due to its praise I've seen

There is nothing wrong with rom's accessibility. All problems are related to webview and gapps. You do know that after flashing Gapps and before flashing Magisk, you must reboot once, so that Gapps could acquire appropriate permissions. Then you can flash Magisk. Also, if you install Google webview, as opposed to AOSP webview included with the rom, make sure Google webview is chosen in Developer settings.

So, if you didn't follow directions re Gapps, then reflash the latest release dirty, then flash Gapps, then reboot. Then back to TWRP and flash Magisk...

Take your time and get to know which feature you have and its location. Most of what you listed is there plus more. Read the OP and do a search on the phone. You'll find charging info on screen, wakelock blocker etc. For example, in Navigation, you will find over 20 options for virtual buttons and hardware button and they don't interfere with each other. Please name any other rom that has that.

Jaguar has absolutely no slowdown. Period. Nothing you can notice with an eye. In fact, the interface is faster, than on other roms. You also have more ram available. Just don't install any modes, as I am yet to see one that offers something usefull, except for screwing the phone. And never restore system partition via TWRP.
