Its a shame a competent community never adopted this phone. The specs and price were amazing, but it seems like no group of devs could settle down and focus on working on a bullet proof rom. AICP 12.1 was amazing for a few months, but then they started intentionally putting out updates that removed features and basic functions, and were reliant on you to flash another groups kernel. Then someone locked the entire thread which i assume is their way of saying they were done with nougat.

Either way, its enough to teach a person that they're better off saving another $100 and getting a Motorola G5 with a proper official rom, and a more mature professional group of fan developers. Even if the specs are less impressive, you dont have to worry about some pushed update killing your sim card, wifi, GPS, etc...

This is excellent, looking forward to seamless AICP support, Lets make AICP great again, one of the minimalist and battery efficient ROM ever. But we are seeing no progress in AICP 13.0, AEX has fixed Almost every major bug. But yes this post gave a hope to look forward.

Looking forward to a big update on this build.

Dirty Flashed the latest weekly over previous build with Nameless kernel.

Working fine, yes, there is bit of slowness, may be due to this diry flash method, but backup has increased. Previous build was heating the phone if wifi sharing was on, so used nameless kernel for relief but this new weekly build default kernel seems to be handling the task well, no such heating issue yet.

ROM is stable and works fluid as daily driver.

Haven't played any major game yet, so unable to comment on that.

SoT has increased a lot from previous build. Was getting 3h 30min, now that has increased over 5 hours and still increasing (as per AccuBattery app).

Idle drain as gone down as well.

Jio network fluctuation continues.

Over all a very satisfactory experience. So far, one of the best fluid performance from any treble ROM.

Thanks.

Which version of nameless kernel? As I'm facing lag while playing pubg
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] NaXal:
Latest version.

By the way, I "had" nameless with last build, but with present weekly release, I am with default kernel !!

Which weekly build of AiCP are you running? Was the installation clean flash ??

Edit 1:-

Played a 35mins match in PubG. As per AccuBattery app, default kernel of latest AiCP build is consuming close to 40% per hour. Really high consumption !!

There wasn't much of lag I faced. Yes, under medium settings there were occasional hiccups but that really rare, like a couple of times in whole 35 mins game. Over all device stayed cool and game running good.

I shall try with nameless kernel and update about performance plus battery consumption !!
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] !error!:
Just after flashing nameless r16 i saw major increase in performance. Played pubg for around 2 hours with a loss of 58% battery but the heat was too much and my device shuts itlself down and after leaving it for 1 hour to cool it down, now my headphone jack is not working. Tried 2 different earphones. Is there a solution or i have toclean flash the rom to fix it??
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] NaXal:
Not a good sign, specially after forced heat related shutdown.

Usually if there is some hardware related problems, it's best to switch to bone stock setup to see if it works.

If doesn't, try claiming warranty.
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] !error!:
Thanks for the advice. Tried restarting 3-4 times and it worked again. Thanks for replying fast i was pretty scared cuz I'm noob:p ...

Any solution for heat?
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] NaXal:
Have you tried the latest weekly built ??

Battery feedback is same with default kernel but heat is much less compare to your experience with nameless kernel.

I am running the present AiCP built with default AiCP kernel.

Regarding nameless, if you have root in your device, install a kernel editor and underclock the CPU/GPU. Refer to the Nameless kernel thread, the first post has those values for playing PubG with less heat !!

If i want to do fresh install(wipe all my data, totally clean phone so its just the aicp rom, gapps and Magisk) what are the steps i need to take?

I have so many minor problems i dont see other people dealing with that i figure the only way to sort them out is a fresh start.(pop ups about missing library files, EQ not working in blackplayer, long-press to turn on the LED, and downright awful battery life[lost 15% over night]). If theres a way to save app data for after i restart my phone, that would be cool to know too, since id really like to have my SMS messages and a few game saves. I have tried free titanium backup in the past, but it only seems to work 1/5 times.

edit- I should add that the reason my phone is probably messed up is from upgrading from AICP Nougat to oreo, and then doing dirty updates each time. Have not had a fresh install since about a year ago when i first put AICP(nougat) on.
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] godlikeu:

May be clean flash help, since I am running via dirty flash from last few build !!

Some AiCP 13.1 build with some version of nameless treble kernel (underclocked CPU/GPU) was the best I found.

Sorry, I have forgot which build exactly, I have wrote somewhere in XDA about that setup. Have to search from a desktop browser to find that post for exact build date and nameless kernel version. (Presently running XDA App so unable to search through all my previous posts).

That setup was cool enough for PubG along with around 11% drain per hour for battery.
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] Arecks27:
Can you please share that setup?
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] NaXal:
As I said, I have to search, not possible for me via mobile app at this time, you can search if you are on desktop browser via my previous posts.

As far I recall, it was may 11 build along with nameless kernel latest available at that date. That version of nameless had underclocked CPU/GPU as default value. Battery backup was great, like 7 hours SoT along with 12-15% drain per hour with PubG.

I'm assuming this is a fully treble supported ROM. so I

1. Flashed Vendor 2Factory_plus.zip

2. Flashed old TWRP

3. Reboot and flashed the rom. Ended up with error 7

I have installed the latest weekly.

Performance is considerably bad compare to earlier builds. It seems with every new weekly the performance is going down.

Touch issue is still present. UI is lagging/stuttering randomly. It wasn't present at this rate in previous build. With every new weekly things are slowing down !!
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] scott86:
Issues: Like others have pointed out, the keyboard lags every now and then(acts as though I am holding onto the letter too long, so I'll get accented letters) and MUCH more annoyingly, my media files are ignored by my media app. I use Blackplayer(cause poweramp is a mess on oreo) and today when i opened it up, all my files were gone. If i navigate to the folder using solidexplorer, i can see they're still there and playable(even through blackplayer) but blackplayer does not see the library in its own library player. If i go to:

settings > storage > Music & Audio > Audio files

its also empty, so the android OS is not see the files as audio. Not sure why/what triggered this, but i think it all happened after i plugged an OTG cable with a flash drive into the USB C port.

I'm so frustrated with it and was already kinda due for a fresh install anyway that i'm about to go through with that. I asked before but didnt get a proper answer, so again, what type of wipe do i need to do? In teamwin recovery, the wipe page has a bunch of options. Cache, Dalvik, System, Data, Internal Storage, Vendor, USB-OTG. If i wipe everything, will that brick my phone(Like, is the 'vendor' part for teamwins partition?)
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] NaXal:
[MENTION=6314516]scott86[/MENTION]

For fresh install wipe everything. Including your internal storage.

Push the AiCP and Gapps Zip file via PC while you are in TWRP after wipe !!

I have done the fresh installation this time around but keyboard issue plus occasional performance lagging issue continue

One thing has improved a bit, that is battery backup !!
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] priorphilip:

[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] scott86:
Did a fresh clean install. Still getting keyboard stutter. Also, the native app library warning for aldiko still pops up when I open the app.

Most annoying is I guess the gapps I installed has a Google app that opens up a search page when I click the home button on the primary homescreen. Really annoying.
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] NaXal:
Home (centre) button Google Assistant activation is due to the touch issue plus some time I too get that while I carelessly touch the home button and end up sliding my finger rather tapping it.

I guess this can be turned off, Google Assistant Home button long press action can be turned off as far as I know.
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] scott86:
I was able to disable it in nova settings through gestures.

Another thing that i figured the clean wipe would fix, but didnt: cant use blackplayers equalizer. Seems the AudioFX gets in the way. I tried forcefully removing it(root app uninstaller), and i no longer get the warning about a conflict with apps, but i also dont get any equalizer effects at all(it just all sounds flat, compared to AudioFX not being great, but atleast having some impact on the music)
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] NaXal:
[MENTION=6314516]scott86[/MENTION]

I am not that into music, so unable to comment on this issue. I do stream music occasionally while I drive via car music system (Bluetooth).

Issue with the typing. Lags like hell
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] godlikeu:
I found those issues appear from build -15, June to lasted build.
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] NaXal:
Thanks for taking the time to dig deep into this.

Another thing that I have noticed is the gradual decrease in performance. Earlier I thought may be due to OTA or dirty flash I am facing this but with last two weekly, I have done clean installation.

Clean installation is always painful since one has to do all the app installation manually, further before installation taking manual file backup and so on.

However, it is clear to me that this performance issue wasn't related to dirty flash.

AiCP was the smoothest treble but not anymore. There are in app slowness, stuttering, UI slow down, stuttering, random lags all around. And rate of this is increasing with every new weekly for some reason.

The worst effected is the touch. Really evident while typing but really painful while gaming or using some high importance app like financial apps. Typing still is something I can go back and rectify !!
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] scott86:
Yup, After a few days of testing stuff out after a clean install(my first one in over a year. I did a dirty update from AICP's nougat build to give you an idea of just how fragmented my stuff was. It was a complete wipe and install too) i can definitely see just about all my issues were more related to rom inefficiencies and not dirty updates. Infact i think my battery life is even worse now than before.

The keyboard lag is the most irritating one though. Every few sentences you can feel it lag and suggest an accented letter(since the lag occurs as you press, so the phone thinks its a long press).

The torch function(long press when screen off to turn on LED) also isnt working anymore, even when enabled in the AICP settings.
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] godlikeu:

Just completed the update via dirty flash from previous weekly running with Nameless R16 kernel.

Update / dirty flashing went fine nothing broke. Just have started using the device for past 15 mins or so with its default kernel !!

Till now haven't encountered the touch screen issue while typing at present !!

Too early to comment on other things. I shall update about my experience after couple of charge cycle !!

Thanks.

Update 1:- idle screen off drain is 1% an hour. Would have liked it to be below .5% !!

UI and in app Performance is okish, nothing great as earlier 13.1 builds not slow or lagging either. But certainly not blazing fast. May be clean installation would give better results over this dirty flash.

Just one charge cycle, battery holding good enough for SOT, over 6 hours !!

Network fluctuation continues, pushed my Jio sim to another handset (Mi Note 5 Pro) and using AirTel with Z2 Plus, even with AirTel as primary SIM, same, if not worst signal fluctuation I am observing as used to be with Jio 4G
