I've been using it for 3 days.

Amazing battery life!

bluetooth works, call work, camera works.

Its just quite perfect right now ^^ :-D

Good idea! This ROM definietly deserve separate thread :)
[Lenovo Zuk Z2 Pro ROMs, Kernels, Recoveries, & Oth] HikL:
Nice to see a separate thread!

I'm wondering, are any of you using encryption? Or just unencrypted partitions? Which recovery do you use? I'm still struggling with boot loops as soon as encryption comes into play.

Wifi hotspot works?
[Lenovo Zuk Z2 Pro ROMs, Kernels, Recoveries, & Oth] Borg666:
Yes, Wi-Fi hotspot works for me. :)

Btw, I'm running Radio 4.0.247_ST_Full on the Z2 Pro.

I did a "dirty flash" upgrading from 9.0, using TWRP-3.6.1_9-0 - and everything worked fine.

From my experience so far, the battery consumption is normal and temperature issue seems to be gone. I'm very happy with this ROM.

To answer my own question for future reference: Encryption does not work since our device doesn't support file based encryption. Only full disk encryption is supported but Android dropped support on that. Therefore the needed password screen at startup does not appear. More info at https://source.android.com/security/encryption
[Lenovo Zuk Z2 Pro ROMs, Kernels, Recoveries, & Oth] Borg666:
Btw, did anyone noticed this nice side effect, as our Z2 now is recognized as Google Pixel Phone?

Google Photos just informed me, that I have unlimited upload quota, as I'm using one of their Pixels. 😅😂👌🏽

"Unlimited photos and videos can be backed up on this pixel for free (original quality)".

It works to backup all my GoPro 4k@60fps footage using my Z2, without touching any of the Google quota, great! 😅👌🏽

Hello, I tried to install the latest version, but I can not pass the initial settings, I did by wifi and mobile data, in none of them I managed to connect to the internet and proceed. Is there any hint on how to resolve this issue?
[Lenovo Zuk Z2 Pro ROMs, Kernels, Recoveries, & Oth] Borg666:
Possibly your Radio might be outdated?

(I'm running Version 4.0.247ST)

Flashing the Radio can fix connection issues, but rately can lead to some as well.

Btw, flashing the radio won't change the displayed "Baseband" version number within the "about phone" settings.

[Lenovo Zuk Z2 Pro ROMs, Kernels, Recoveries, & Oth] Barkuti:
Hello fellows! 🙂

Is this ROM seriously working as it should? 🤔

A few months ago I downloaded the Android 12 AOSP ROM (I a see an AEX v9.0 version in the download page, must be it) and it basically was a mess, to put it clearly. This of course is not to blame dmd79 in any case, I am fairly grateful for what he has done ROM wise to the Zuk Z2 Pro or Z2121. Really! 🙏

But I have to ask, because things like the options in the Developer Options menu were basically not working, or at least there were many items which I just couldn't change, or they did not seem to work. There were many other problems with the Extensions menu in Settings.

Still, can't help to say that I found really annoying the way Android 12 manages notifications, as for example I use Power Toggles as quick application launcher which displays as a permanent notification in my status bar drop-down menu, and Android 12 displayed some annoying additional text ribbon above or below it for whatever stupid reason which I couldn't remove. I uninstalled that ROM version pretty quickly anyway. I also still think Oreo 8.1 AEX v5.7 is the best ROM you can use in this device anyway, but given that overall I really dislike all newer smartphones due to super disproportionate screen aspect ratios (I use landscape 99% of the time), ultra-high screen to body ratios which I simply dislike and have resulted in every manufacturer dismissing the presence of a super-practical navigation button and sensor like the one which the Zuk Z2 Pro has; aaand, well, the outright retarded HUGENESS of the majority of newer devices, I seriously think I'll keep my Zuk Z2 Pro for a few years more. I know how to replace batteries anyway, and I also know how to make them literally last for ages by limiting maximum amount of charge (65%) or voltage, esentially. Ultra-mega long life for the Zuk Z2 Pro! LoL! 🤣

Thanks a lot again master ROM creator Davide Della Maddalena! May the Light of True Source be with you, and may your life be prosperous and happy if so is your will! 🙏

Best regards and cheers everyone! 😇
[Lenovo Zuk Z2 Pro ROMs, Kernels, Recoveries, & Oth] Borg666:
I think it's a personal discision wheather someone likes the general Android 12 behaviour or not, imho?

Which Developer options are you missing in particular? i tried some, they all worked well for me (9.1).

Regarding gestures I switched to an external App since 8.x, pretty satisfied with it's functionality:

Edge Gestures - Apps on Google Play

Just swipe the edge to do something!

play.google.com

Regarding spares battery, could you please recommend a specific battery type or any additional tools needed, e.g. from AliExpress?

Is the exchange process also suitable for beginners as well?

Cheers, Borg
[Lenovo Zuk Z2 Pro ROMs, Kernels, Recoveries, & Oth] Borg666:
Hi Barkuti,

Thanks a lot for your extensive recommendations - a battery, tool set and some glue tape was ordered. Looking forward to get back on 100% battery capacity.

As my device isn't rooted, I was using "AccuBattery" for the past years, which does a pretty good job for nonroot Users:

[Lenovo Zuk Z2 Pro ROMs, Kernels, Recoveries, & Oth] Barkuti:
Oh! I found a seller (just one!) which still sells the specific adhesive of the Z2 Pro back cover here. It's not cheap (I see it for $3.91 + $1.88 S&H), but I refuse to pay too much for the stuff I buy and I wouldn't buy such a thing. The adhesive requires careful placement, so better don't miss. And a full, new back cover (which comes with integrated adhesive) costs just a few bucks more ($9.04), so I would personally not buy the specific adhesives. With the double adhesive tape you can cut a few pieces of it with the right lenght, and place it in the desired spots of the back cover until they all are properly covered. If you miss a placement, you quickly remove the adhesive with a spudger and start over. Takes some more work time, but it'̀s a lot cheaper in raw material cost. And on top of this you will also keep a nice roll of thin double sided tape for other purposes.

Tad off-topic, but for example look at this seller advertisement. I see it asks $10.81 + $4.47 for 2 pieces of the smaller Z2 back cover adhesive. Even if it is 2 pcs, I call that a rip-off! 🤦 Can buy a Lenovo logo Z2 new back cover for $5.38! I've personally bought these back covers, and they look pretty good!

P.S.: I do not mean to be judgmental, but if at this point you don't think I deserve at least a “like!”, I'll have to say shame on you. 😂
[Lenovo Zuk Z2 Pro ROMs, Kernels, Recoveries, & Oth] maekus69:
Hi,

Before I start from the scratch, I'd like to ask first.

Preinstalled GApps.

Btw, which GApps were used? Flame? MindTheGapps?

Preinstalled Play Store 28.xxx.

After updating -> 30.xxx.

But after restarting I'm back to 28.xxx and have to update again. Each time.

Anyone else having this behavior?

Some information:

Before I used AEX Pie for a long time without any problems.

Did a clean update, i.e. system, data, cache and dalvik wiped.

Thanks.
[Lenovo Zuk Z2 Pro ROMs, Kernels, Recoveries, & Oth] Borg666:
Hi Maekus,

My Play Store Version reads 30.0.20-21 [0] [PR] 439708378

Never experienced any forced downgrade ever. 🤷🏼‍♂️
[Lenovo Zuk Z2 Pro ROMs, Kernels, Recoveries, & Oth] emilic:
Personally, I find that the battery is really good, better than aex8 ^^

That said I do turn off my cell network at nights and I do try to optimize who gets or who doesn't gets internet access.

I have never tested the app ACCA from above to handle the battery charging... But I do use accubattery to always charge my battery to 80% max, I've found that this has helped my battery to live longest :-)

(I've had my zuk z2 pro since 2017 and I've only changed 2 times the battery...)
[Lenovo Zuk Z2 Pro ROMs, Kernels, Recoveries, & Oth] emilic:
Mine states 30.6.16xxxx

have not seen it moving.

Gut again no idea which GApps are being used... I just used the ones that came with.
[Lenovo Zuk Z2 Pro ROMs, Kernels, Recoveries, & Oth] maekus69:
Thank you Borg666 and emilic.

I will try to install GApps by TWRP.

Btw, I didn't flash GApps before.

Until now I used the preinstalled apps.

If that won't fix my problem, I guess I have to start from the scratch.

Picture 1 after update.

Picture 2 after restart.
[Lenovo Zuk Z2 Pro ROMs, Kernels, Recoveries, & Oth] Borg666:
Ooops, I have to admit that I'm affected of this topic as well. I didn't know that the PlayStore is updateable within it's settings, to be honest. ☺️🤷🏼‍♂️

This version is offered and was installed as an Update: 30.9.30-21 [0] [PR] 454218620

After reboot I'm ending up with 30.0.20-21 [0] [PR] 439708378, again. 🤷🏼‍♂️

But anyway, I never felt issues with my Version of PlayStore so far.
[Lenovo Zuk Z2 Pro ROMs, Kernels, Recoveries, & Oth] maekus69:
@Borg666

Thanks for the info.

But after flashing Flame GApps

FlameGApps-12.1-full-arm64-20220612.zip

Play Store seems to be OK. Other apps, too.

Waiting for the next Store update to test.

But my biggest problem was no LTE/4G (Germany Telefónica o2).

I flashed Z2Pro_Radio_Modem_4.0.247_ST_Full.zip again and again but no chance.

I knew there was a problem, I fixed before (years ago)...

And found the thread I used:

https://xdaforums.com/t/radio-modem-basebands-for-zuk-z2-pro-only.3715835/

After fastboot fixing everything was OK.

So far the ROM is OK.

I can reproduce some errors if I go deeper but these are things I do not really have to change.

Magisk/root working well.

I like this ROM.

I really appreciate what dmd79 did for the ZUK Z2 Pro.

Great job. I hope he will go on. Really.

And I hope minor bugs will be fixed in future.
[Lenovo Zuk Z2 Pro ROMs, Kernels, Recoveries, & Oth] Giogts:
What minor bug?
[Lenovo Zuk Z2 Pro ROMs, Kernels, Recoveries, & Oth] maekus69:
Hi, I will try again when i made a backup but when activating "Scramble PIN Layout" there was no layout anymore.

I had to delete locksettings with TWRP to bypass lockscreen.
[Lenovo Zuk Z2 Pro ROMs, Kernels, Recoveries, & Oth] Borg666:
Does the version of FlameGApps support auto update, or do I have to download this manually from SourceForge and update manually each time?

https://sourceforge.net/projects/flamegapps/files/arm64/android-12.1/2022-06-12/FlameGApps-12.1-full-arm64-20220612.zip/
[Lenovo Zuk Z2 Pro ROMs, Kernels, Recoveries, & Oth] maekus69:
Apps were updated by Play Store. So I'm quite sure you don't have to update manually. Working like the preinstalled apps.
[Lenovo Zuk Z2 Pro ROMs, Kernels, Recoveries, & Oth] maekus69:
What's working?

Magisk tested. Stable and canary without problems (emilic confirmed that before so it's for sure).

SafetyNet -> Basic integrity + CTS profile match = pass (Magisk + Universal SafetyNet Fix).

Play Store -> Device is certified by Google.

GCam tested. I use old version (6.1) I used for years. No problems. Much better quality (HDR+) and night vision + slow motion OK. But will test newer version later.

Borg666 -> "Unlimited photos and videos can be backed up on this pixel for free (original quality)" -> confirmed

yes, I can set it to automatic but it doesn't work I have to do it manually I don't know why. I put the ROM clean so no idea..

edit:It works now after reboot a couple of times
[Lenovo Zuk Z2 Pro ROMs, Kernels, Recoveries, & Oth] maekus69:
Hi xino22, it

could

be your sensor drivers.

They are part of the persist partition.

Do you have a TWRP backup of your persist partion?

Then flash it again.

If not or if that won't help you could try to flash a newer persist partition.

You find flashable persist.zip here at XDA.

Latest version there is 4.0.233 but there should exist 4.0.247.

ZUK Z2 Pro persist.img files flashable by twrp / adb

Question:

Do you know which ZUI Stock ROM was installed before you started to install a custom ROM?

Did you ever update your ZUK to the latest ZUI ROM before?

Custom ROM installation does not update all partitions.

The best would be to install Stock ROM and update to the last one step by step.

Then unlock bootloader and install your ROM.

Good guide here.

[HOWTO] Flash a Stock ZUI ROM (ZUK Z2 Pro Z2121 only!)

But that would be the last step I would try. Takes some time...

IMPORTANT:

ALWAYS MAKE A BACKUP OF

ALL

PARTITIONS BEFORE FLASHING ANYTHING.
[Lenovo Zuk Z2 Pro ROMs, Kernels, Recoveries, & Oth] emilic:
Well after now 1 month of using this ROM

I am still quite happy with it.

BUT I've found out recently that my phone is heating up a LOT and that my battery is also not lasting as much... And even charging was taking longer than usual...

And actually when charging and just turning on the device I found out (for the first time, had not seen this in other roms) that the battery was charging at voltages going up to 9v and high Amps too. I used to only have 4.5v charging and then higher amps.. so I am wondering if this rom is correctly regulating the charging...

I will look into using the app that someone mentioned above to regulate charging, as this may be the issue that is getting my phone warmer and "damaging" my battery.

Again this is just a feeling, I am not sure of what exactly is going on.
[Lenovo Zuk Z2 Pro ROMs, Kernels, Recoveries, & Oth] maekus69:
I can confirm heating up mobile but it's not the battery. Cores are running quite high. Especially after system start the board is getting hot. I thought it were my apps or root I installed later. What I did was using AccuBattery (will test ACC/ACCA later) and stopping apps running in the background. Better now and I can use the mobile a day but it really seems to drain the battery faster.
[Lenovo Zuk Z2 Pro ROMs, Kernels, Recoveries, & Oth] emilic:
I've installed the beta version of Better Battery Stats to see if I can see what's going on. And I confirm that the CPU is running at max most of the time... Still waiting for more stats
[Lenovo Zuk Z2 Pro ROMs, Kernels, Recoveries, & Oth] maekus69:
I'm guessing a Google app. :)

I did some tests with Governors tweaking.

I used "3C CPU Manager (root)" and it seems that only powersave can slow down cores.

But then system gets laggy. But I will test on.
[Lenovo Zuk Z2 Pro ROMs, Kernels, Recoveries, & Oth] splitterfaenger:
I also have heat issues. The Phone heats up to the point were it is barely touchable. CPU seems to be running on full power, although there is no major app running. ACCU Battery does not give an indication if any process is consuming a lot of power.

I'll try power safe mode next. Does anyone have a solution yet? Could a fresh install of the ROM help?

EDIT: The Displayed Values for my CPU seem static, when using the "normal" mode. In power safe mode the CPU seem to change dynamically. Also, in the power settings I can see that "media storage" (or "Medienspeicher" in german) is used the most, even after restricting the usage in the background.
[Lenovo Zuk Z2 Pro ROMs, Kernels, Recoveries, & Oth] Borg666:
Do you know if there's an certain advantage of "your" Flame GApps over the well known OpenGApps on our device?

The Open GApps Project

OpenGApps.org offers information and pre-built packages of The Open GApps Project. The Open GApps Project is an open-source effort to script the automatic generation of up-to-date Google Apps packages. All Android versions and platforms supported.

Thanks! :)
[Lenovo Zuk Z2 Pro ROMs, Kernels, Recoveries, & Oth] Borg666:
in my point of view, any App which causes larger data usage could be the culprit for this behavior. In my case it was Google Chrome - in special, the synchronisation of Google Chrome, which led to high battery usage of Google Play services... 🤷🏼‍♂️

Maybe it could be something similar in your case, so that the media storage is only the effect, but the cause could be somewhere else?

A possible work around could be, just stop the app/service, and delete all app data.

After that restart the app - this could solve such kind of issues. 🤷🏼‍♂️
[Lenovo Zuk Z2 Pro ROMs, Kernels, Recoveries, & Oth] maekus69:
Take whatever you like more but until now there's no stable OpenGApps for Android 12 as far as I know.

;)
[Lenovo Zuk Z2 Pro ROMs, Kernels, Recoveries, & Oth] maekus69:
I can confirm that it's hard to find the real cause of battery drain.

But i see heavy battery drain and heat with Torque and Google Maps.

Both use location and Torque needs bluetooth in addition.

The behavior is reproducible.

I will test a few days with GPS and bluetooth turned off.
[Lenovo Zuk Z2 Pro ROMs, Kernels, Recoveries, & Oth] Borg666:
Oops, I guess that point goes to you. 😉

Do you know if it is possible to flash the GApps versions back and forth between the different versions (e.g. FlameG->openG->whateverG?), in order to be able to switch to open-g-apps later on, when they're available then?

My intention is to flash newer GApps in order to get rid of my temperature/battery issue with regards to Google Play services (in my case Google Chrome synchronisation)
[Lenovo Zuk Z2 Pro ROMs, Kernels, Recoveries, & Oth] maekus69:
Should be working but a clean installation should be prefered.

If you want to you could take the OpenGApps 12L test version.

[Lenovo Zuk Z2 Pro ROMs, Kernels, Recoveries, & Oth] Barkuti:
Yes Borg666, I know these adhesives very well. In my experience with the stuff, I can say that there are a few brands and a bunch of denominations being used. Zhanlida is a very well known brand, with B6000, T8000 and T7000 among its adhesive denominations. These adhesives are basically the same, with only small variations in formulation like slight density changes and different adhesive color tone (T7000 is dark color). In my experience, they all work well and are a must for smartphone repairs, being slow to cure adhesives which work well for lots of things. For example, it is common to use battery adhesive tabs and other commercial gimmicks, but in practice a bit of these glues is all you need to properly fix a battery without problems, saving some money.

Money is precious to me. I spend with great care. My latest adhesive buy was a pair of 110 ml tubes of Bulaien B-7000 adhesive from here. Paid less than $7 for them, and of course my adhesive is sleeping in a drawer at home since some weeks ago.

For genuine Zhanlida T-7000 to Germany, grab some here and save money. 😉
