I clean flashed and dirty flashed both but Volte is crashing after 3rd/4th reboot. I was busy with work so couldn't test the ROM thoroughly. And using it without volte is pretty tough during work. So I am waiting for stable volte build. I hope it is soon. . Fingers crossed ?

May 8 release (and before) never had any volte problems. So, if you don't have volte there, it is not the rom.

For June release: check your apn settings, as those might have been updated. One wrong entry may screw volte. Get settings from your carrier.

Thank you for the amazing work so far, I just had few questions.

1. Did you re-upload on the same link after fixing camera delay? I downloaded in morning so do I have to download again to get it fixed?

2. Not sure if its just me but phone battery works fine throughout day but when I wake up after sleep at night, I find it drained quite alot than usual, Works fine during day in single charge.

3. How do you take screenshots? xD

Also, My power profiles shows error, is it because I didn't flash magisk?

Thank You.
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] UzE ™:
The link for latest build should be in third post

Check which apps are causing idle drain or if it is due to mobile standby

To take screenshots either long press the screenshot qs tile from QS menu or long press power + volume down button.

The best way to fix that is just wait for the next build.
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] optimumpro:
All rom updates are in post #3 in this thread. The latest one is on top, and it does have camera fixed. Volte is the only problem. So, if you need it, stay on May 8 release.

Profiles require root. Install Magisk. Go into profiles, pick one, click OK and grant root when prompted. No reboot is necessary.

Edit: to take screenshots, either use QS tile or 'power' button plus 'volume' down. Volume up is for screen recording, or the other way around.
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] optimumpro:
Post #3 in this thread has the link. As I have already said, the only problem with June 9 release is Volte (camera has been fixed). If you require volte, stay on May 8.

I would flash clean.

On my previous device I couldn't do both . if volte wasn't present.
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] adil786ali63:
SMS are not dependent on Volte functionality bro... text messages can be easily transfered over normal network coverage without volte :)

Oh i see my bad.. Thx for heads up.:good:
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] UzE ™:
Nope , SMS needs functional VOLTE with a VOLTE sim card .

So maybe VOLTE is half broken , and most probably the ims isn't working which disappeared after reboots.

You can verify this by disabling VOLTE and see if you receive any SMS .
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] GopalKaul:
Nope. On my nexus 5 which is 4g non volte you can get SMS of missed call and all. You can't send but. Verified by me!

Hi, and thanks [MENTION=5075064]optimumpro[/MENTION],

Different rom tested, Jaguar is the best (Nougat and now Oreo), managing 4 Zuk Z2 Plus. It is fast and stable, good battery, encryption, two sims, no gapps (microG), magisk, and for sound AML, Ainur Sauron and JamesDSP. Bluetooth sound is good...

- aren't sound modules useless with Jaguar basic sound features ?

- Should I remove KA power settings with AKT ?

- April and 8 may releases break SSHelper ("server initialization problem" -was fine before-). It works with 28th may release and june 9 break it again. I don't know what to do, an idea ?

- Airplane mode is required to register second sim (all releases), keyboard "disappear" too quickly when booting phone.

Thanks again

[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] optimumpro:
Try to flash that older zip that fixed volte on early Oreo. The problem is android is set up in a way that blobs are not cleaned out on change. So, blobs with different names stay in system. What I did was a clean build and those blobs are now gone. This happens when people introduce new blobs and things seem OK, but they are not, since old blobs are still working, but when you do a clean build, those old blobs disappear and things get broken.

If you have 'apply on boot' settings in KA, they will override AKT, because KA comes in later. So, untick 'apply on boot' and profiles will hold.

[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] UzE ™:
Yes LTE is working but VOLTE is not, so you will be able to access Internet but won't be about to call anyone even though you can receive SMS .Also jio 4g voice app won't work as it show that the device supports VOLTE.

I m not on jio, I use Airtel which doesn't have VOLTE (Voice Over LTE) so I m asking for me it's like everything is working right?

And LTE for data (internet 4G) only and normal calls will also work ?

I m confused a little if anyone can explain pls... because In my knowledge Airtel never used VOLTE so I didn't have any issues until now but last 3 release everyone is just VOlte and all...if m right about Airtel that it doesn't use voice over LTE than this rom doesn't have any problem for me and many other Indian users who don't Jio VoLTE right?

So please tell me, is it best to flash 8th may release? If yes, should I flash clean or dirty.

Please also tell, in TWRP, what all I need to clear, like dalvik cache, data or what. And also do i need to flash gapps and magisk again?

Seriously your work has made my Zuk Z2 from being a regret purchase to the most fun phone I've even owned. Especially after coming from Galaxy S5 whose software really bothered me daily.

Hey guys.

I am having a problem.

This year, my rear camera and flashlight stopped working on my Jaguar Nougat r15 rom. Only the front camera worked. There was no option to toggle to the back camera. I thought maybe it was a software issue.

Today I clean flashed the Oreo May8 rom.

Everything's working well, except the camera. It crashes every time. I even tried Gcam but to no avail. I still can't use my flashlight. The icon is greyed out.

I am very worried.

Is this a hardware issue? Please advice.

I am having a very strange issue with this ROM. I am a (legal) owner of Sygic Aura, which stores data (maps, etc.) in ..../Android/data/com.sygic.aura after each reboot, this folder is completely empty! I don´t even need to launch the Sygic App, I can just put a dummy file in ..../Android/data/com.sygic.aura, reboot and the folder will be completely empty again. The same (of course) happens if I start the Sygic app, let it download some maps, etc., the folder gets filled with many different files. Restarting the app without a reboot works fine, everything is still there, but as soon as I reboot, the ..../Android/data/com.sygic.aura is completely empty again. What the heck is this? I can´t make any sense of this problem and it only happens for this app, all other apps keep their user-data in the subfolders of ..../Android/data/, just Sygic directory, even though the app is not even started, loses everything as soon as the system is rebooted. If I rename the "com.sygic.aura" directory to something else like "com.test.aura" and put files into it, then reboot, the files are still there after that reboot. But as soon as I rename it to "com.sygic.aura" again and reboot, the directory is empty again. This ALSO happens after I´ve completed deinstalled the whole Sygic app and all of it´s traces. It´s like Android is deleting everything in the directory on each reboot as soon as it´s named "com.sygic.aura". Going back to Mokee 7.1 ROM and this problem goes away too, so it must have something to do with this ROM. ANY ideas guys? This one is driving me crazy diagnosing...
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] crazyguns:
Settings, Developer options, enable camera+ hdr hal, reboot.

Weird that its happening on this rom. Might be something to do with the way sygic detects security? It could see selinux is permissive and wipe its app data as an anti piracy measure or something. The os definitely wouldn't wipe app data like that though, it must be something in the os that sygic doesnt like and refuses to work normally.. Maybe if you're rooted try converting it into a system app using titanium backup, so that it cant wipe itself.

I've had no issues with the latest build, rock solid stable! Thank you Dev!
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] dabugen:
Thanks for your reply, however, as I mentioned, this happens even though Sygic is completely uninstalled at this moment. And even if I delete and recreate that directory on my own. As long as it´s name is "com.sygic.aura" in /Android/data, any content gets deleted after a reboot, but stays just fine without any reboot - even if the actual Sygic app is not installed anymore. This all makes no sense...

Is there a way to trace which program is deleting the files upon reboot?
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] udeshvirk:
Thanks bro, I am facing one more strange issue.. I am not receiving any call... I am on Airtel and VoLTE is not required for this... anybody else facing this issue?? Will clean flash fix this??? I did dirty flash from May 8 build

I think its not a general issue, as my sygic stays in place after reboot(made a fresh install). Any changes you made after flashing which may cause it?

Edit- yep my file is still there, hasn't been deleted. What else do you have on your phone, any ccleaner type apps? Try using a logcat to see if some app is deleting it... Ohh maybe the Google backup and free space option is ticked, realising the app no longer exists and is deleting it?
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] dabugen:
Thanks for that test, much appreciated! I am short on time right now, but I will try to catch what´s causing this. No cleaners, nothing, app installed / not installed makes no difference (hence can exclude Googles App syncing too).

[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] optimumpro:
That may be due to an AKT profile you are using. If you pick 'jaguar performance', you will have no lag whatsoever.

Check for access storage permissions in Settings/Security/Privacy and in Settings/Apps. Remove any such permission from apps you don't need. If that doesn't help, format your SD card space, as there might be some leftovers from other roms.
