Installed last OTA with AEX 4.5

-Thermal control seems to work better now, no more overheating problems, even after flashing the temperature of the device seems normal.

- Everything looks to work fine, GPS, Vibration, Wifi, 4G network, Camera, Fingerprint sensor.

Will be possible to port Uhealth from ZUI and be able to use the health sensor and the UV sensor?

Thank you again for your awesome work.

[MENTION=2823824]davidevinavil[/MENTION] Thanks a lot mate for this great update!

- fingerprint is working much faster now

- Antutu is working again, showing about 140k, but it may be higher later on.

- no noticeable heating anymore, thanks for this!

- scrolling is more smooth and fast now again, was laggy before.

Keep on going with your really good work! And thanks for fixing bugs fast so we dont have to wait months but just days, you are crazy great :)

[Lenovo Zuk Z2 Pro ROMs, Kernels, Recoveries, & Oth] greedy94:
Two questions : why full ZUI (for QFil method) takes 1,5Gb, it's three time the size of custom ROM ? Does it contains sensors updates ?

What is the ZUI pre-requisite to install AEX over ?

I mean it's better to have 2.5.335, 435 or 462 before a clean install of AEX 4.5 ?

[Lenovo Zuk Z2 Pro ROMs, Kernels, Recoveries, & Oth] Bryandu13:
Anyone else have this problem ? Gaming became laggy, when I back to 4.4 performance become great again, is there a correct method to update properly or the 4.5 is laggy for everyone ?
[Lenovo Zuk Z2 Pro ROMs, Kernels, Recoveries, & Oth] MRDA1981:
Haven't played any games , but Antutu scores are in the 11-12k range, lower than RR's 15k; otherwise, performance doesn't feel noticeably laggy, if at all.
[Lenovo Zuk Z2 Pro ROMs, Kernels, Recoveries, & Oth] Bryandu13:
Same Antutu score, I feel lags when I open Facebook, when I receive a messenger message on an heavy app/game, in multitask etc...

I mean it's not really "laggy" but I'm 100% sur that it's really slower than 4.4

[Lenovo Zuk Z2 Pro ROMs, Kernels, Recoveries, & Oth] jlpe12:
I noticed that using 3.1.1 version of TWRP for ZUK Z2 Pro the device is shown as "Z2 Plus" when you connect it to a laptop or PC to use it for MTP

Probably this change could involve problems while installing other ROMs due to wrong device (z2 row vs z2 plus)
[Lenovo Zuk Z2 Pro ROMs, Kernels, Recoveries, & Oth] yomama163:
Flashed AEX and tested it for a while. Great rom, fingerprint works like a charm and it looks stunning. Only problem right now is that I can't pass SafetyNet. I did a clean QFIL install from the beginning (1.9x) to relock my bootloader and updated it to the newest ZUI in existance (ZUI 2.5.462 ST) and then unlocked bootloader, flashed recovery, flashed the ROM. I didn't install any root, still CTS profile mismatching. Did I forget something?

EDIT: got SafetyNet working by changing the build.prop. Guide provided HERE in case someone doesn't have the Universal SafetyNet Fix module provided HERE (I can't get into the group because my phone number is invalid for some reason)

Requirements are a clean build.prop from a stock ZUI rom which passes SafetyNet, doesn't matter which Android version. I assume that you have to do this fix every time AEX updates their firmware, so keep your modified build.prop somewhere on your sdcard and replace it as soon as an update is being released
[Lenovo Zuk Z2 Pro ROMs, Kernels, Recoveries, & Oth] xaviermaluenda1:
Does this ROM do the same as OP3T? Overclocking for antutu? Because in AEX 4.4 I could score close to 135,000. And now I have a score of 143,000, but I can not compare with other cell phones. This happened to me when I overclocked him.Thank you, I just want to know. The ROM is great!

overclocking with Z2 Pro brings 156-158k with modified kernel in RR 5.8.3.

RR 5.8.3 unmodified brings 150k.

So everything up to 150k seems not oberclocked to me ;)

[Lenovo Zuk Z2 Pro ROMs, Kernels, Recoveries, & Oth] void23:
Quite true, but only with a modified thermal-engine.conf. Default is just too low I'd say. Phone barely gets warm....

Anyway, it's a pitty there's not more overclocking headroom on this device.

EDIT: With attached thermal-engine.conf (which is still conservative!) I get close to 155k in AEX 4.5, no overclocking. Just replace in /system/etc and reboot.
[Lenovo Zuk Z2 Pro ROMs, Kernels, Recoveries, & Oth] weimerd:
I just answered to the overclocking question right before my answer. However you are right: I dont want to discuss difderent roms here as well so lets stay at AEX here ;)

Is it possible to implement the uhealth app, so we can use the sensors of the phone?
[Lenovo Zuk Z2 Pro ROMs, Kernels, Recoveries, & Oth] weimerd:
several problems:

- Uhealth is not open source

- Uhealth needs ZUI framework to work properly

- Uhealth is not multilanguage which would be against the idea of AEX to be a multilanguage system

If someone would do a port of Uhealth app to be installed on various roms: That would make sense :) Like an optional addon, flashable by twrp.

But I think integrating it to a rom is the wrong way.

Hi guys quick question since I am interested in buying a Z2 Pro (living in germany atm): Does Pokemon Go work flawlessly on the Zuk Z2 Pro (6/128gb version)? Would it work on Stock, too, or is it necessary to install a custom rom to enjoy that phone? Thanks for helping guys! :)

[Lenovo Zuk Z2 Pro ROMs, Kernels, Recoveries, & Oth] Terminator.J:
I have a Z2121 6gb/128gb back Z2 Pro, and it works great for me.

While I've not tried it on stock with a locked bootloader, I've run it just fine on all of ZUI 2.5 releases so far with unlocked bootloader using Magisk 12 & 13 to hide root and adjust props to pass SafetyNet.

I gave up on ZUI for being a colossal pain, was on RR for a while but I'm not a fan of having no idea what the status of development is, and AEX seems great, is under active development, and hasn't crashed to blue LED yet trying to have the alarm go off, so I'm staying with that.

It's something I enjoy playing it with my wife, so I go to some lengths to make it work on whatever phones we're using.

[Lenovo Zuk Z2 Pro ROMs, Kernels, Recoveries, & Oth] weimerd:
really weird. I came from 2.5.435, then deleted system, data, dalvik, cache and then installed AEX.

As we have the same otg adapter it must be some other differences between our installations.

I want to come back to the Camera-app issue. Has anyone tried to get the stock ZUI camera working on the latest build? Because in the latest kernel sources on Github, I can see that some ZUK blobs and other stuff in this regard was integrated. I don't know if the full build of the ROM was changed however. Maybe flashing of stock camera would work now? I have not tried yet...

Camera is really the only issue I'm still leaning towards ZUI. Would be fantastic if we could have the stock camera on AEX!
[Lenovo Zuk Z2 Pro ROMs, Kernels, Recoveries, & Oth] greedy94:
Not working today. The ZUK Camera is using a ZUI framework and it's not as simple as installing an app.

I'm back to ZUI for the ZUK camera and because I've found that 2.5.462 is also more consistent on the 4G/Wifi side for me than AEX last built I have tried (clean install for both).

No 4G drop in subway/train, no Wifi loss at home without reasons... Maybe the 462 build update some drivers and correct some flaws.
[Lenovo Zuk Z2 Pro ROMs, Kernels, Recoveries, & Oth] void23:
I know it's not a simple app to install, but there's a TWRP flashable zip (ZUI.Camera.test1.zip) floating around, which should include necessary framwork components. At least I thought it would.

Anyway, I've just tried it and it didn't work. Probably needs more messing around and/or further AEX modifications. After manually copying and overwriting the files on /system, the stock camera app would open without FC, but black screen and syslog messages like "Cannot connect to service media.camera." Tried restarting cameraserver, but no, black screen and app hanging. Then I tried a reboot and the device got stuck during boot. Had to restore from backup... :o

[MENTION=2823824]davidevinavil[/MENTION] said that there's a "big, big change" coming with the camera, so the blob-importation may be just the first step in implementing that. Personally, I think he should team up with *PRATHAMESH* to tweak Camera Next Mod v7 to full functionality with this phone (or at least steal whatever blobs he's using! :P); I always get much clearer, more solid-looking pics with that than ZUI stock cam, which always gives me noisy and smeared results: https://xdaforums.com/oneplus-one/themes-apps/mod-cameranextmoddenoise-feature-t3393254

(I will say I dig the interface of the ZUI Cam more than the Cyanogen Cam's; why do so many apps have the cam-flip button at the top of the screen?)

Anyone got AndroidAuto to work?

Hi All,

It is my first post here after deciding to flash this rom about a month ago. Currently at the build of August 10th after clean install.

I'm really happy with this rom and would like to thank [MENTION=288244]daviden[/MENTION]avil for his great efforts.:good::good:

My biggest gripe so far is that I can't get AndroidAuto to work in combination with nav system of my car (VW discovery pro). When plugging into the USB port, my nav system recognizes the phone (device name as something like "Shenqi Z2"). But when trying to connect, it reports the connection is refused. I've tried all different usb setings on the phone. Anyone succesfull in connecting androidauto? And if so, how did you do it?

[Lenovo Zuk Z2 Pro ROMs, Kernels, Recoveries, & Oth] BuMa67:
AA not working

Hi aauer4man,

Good question. Actually, I don't know. My ZZ2Pro came with a global ZUI rom flashed on it by a reseller. Being wary of malware some resellers implant, decided after a few days to flash AEX rom. And it was before I tried connecting it to my nav system with AA. So if anyone was succesfull using AA on ZUI rom, I'd be interested to know.

Was fiddling with it yesterday once again. On one occaision (which I wasn't able to replicate therafter) I got an error message on my phone screen telling me the Google Play framework on the nav system was outdated, as well as wrong time & date. I can't actually believe the google play framework is outdated; I've installedthe latest OTA update on the nav system. And obviously, date & time aree' set correctly.

Will try to replicate the rrror message and make a logcat; I wasnt successfull yesterday when I tried to.

Cheers BuMa.
[Lenovo Zuk Z2 Pro ROMs, Kernels, Recoveries, & Oth] aaur4man:
I have difficulties to get AA as well. Bought new cables as what AA discussion had recommended , but could only get it to work for 5mins uninterrupted at best.

Another z2 pro owner gave up and bought an old Nexus instead.

I have 2 other phones that can work with my unit with no problems.

Tried zui 1.9, 2.5 , RR 5.8.3, AICP but to no avail.
[Lenovo Zuk Z2 Pro ROMs, Kernels, Recoveries, & Oth] BuMa67:
On one hand happy to hear it's not just me struggling. But your feedback gives me only little hope connecting to AA will work at all with our ZZ2 pro.

Can you eleborate a little more how you got your device to connect at least for 5 minutes?

And referring to the post by Tikilou in this thread(August 11, 2017 | 6:15am, sorry can't quote him as I am a new member) he refers to the latest ZUI build (2.5.462 ST) to have new firmware updates included.

I come from ZUI_2.5.335_ST_170116 and did not return to ZUI 2.5.462 ST before flashing the latest AEX 4.5 build.

Tikilou stated the latest ZUI build have firmware updates included. And just my speculation, but these updates may solve AA connectivity errors we are facing. What was your latest ZUI version before flashing AEX v4.5? En was it a cleanflash or a dirty flash?

As AA connectivity errors apears to be more generic to ZZ2-Pro and not limited to AEX ROM, it seems more opportune to find (or open new) thread where we can further discuss. As you seem to be struggling with this issue for a longer period already; any recommendation for an existing thread?
[Lenovo Zuk Z2 Pro ROMs, Kernels, Recoveries, & Oth] aaur4man:
