I know. Jio is in SIM one only !!

It was working fine since last few months.

Today morning I swapped out Jio SIM card to put it in another phone. Later in evening in hurry I made a mistake and did hot swap to put the sim back again. And that it's, VoLTE is gone.

Tried everything from settings to reflashing the ROM it self. But no help.

I did make all preps for ZUI route but before proceeding, thought no harm in doing a full wipe and trying clean flash the ROM to check VoLTE !!

It worked !!

So here is what I did, wiped everything, including internal storage format. Pushed the ROM file and GApps in phone while in TWRP. Flashed them both and reboot !!

Update on latest weekly with PubG. Default kernel no other mod, no root either.

I heat is really low. No doubt, one of the lowest I have seen so far. However having a lot of stuttering and lags. Difficult to aim a moving enemy due to this stuttering and lagging.

Game settings are as determined by game itself, medium. Didn't fiddle with them yet.

If you are in higher league of PubG, you may face great trouble with skilled enemies.

Battery consumption is around 30% per hour with LTE data connection.

I shall try nameless R17 to check if any improvement.

Thanks.

Update 1 :- Player a couple of match with Nameless R17. Device is still running much cooler when playing this heavy game. So far still the coolest (same as default AiCP kernel). Lag is almost gone with Nameless R17 (under medium settings). I shall update after few days of use about battery with Nameless R17

has anyone managed to get custom ringtones to work? I have them in a root folder called "notifications" but i cant see them in my "media storage"(default app) list and if i scroll all the way down to "+ add ringtone" and navigate to them in the notifications folder, it still shows "none" as selected. The files are .mp3, .wav, and .ogg and WERE working fine before i did a clean install of the newest rom. If i used a different file managed to select them(Solid explorer) i get the same results.

Hi there folks i have some questions if possible can someone help out?

1) Looking around i found some people talking about audio being to weak and some changes in the file mixer_paths.xml, well my audio is very weak and for some reason i cannot find this file.

2) DivineBeats doesn't work with it even disabling linux enforce...

3) The Magisk version pointed to use with this rom for me always give errors and some apps that i want to have root access are giving some errors...

Any idea guys, anyways sorry about the questions but other than that this rom is freaking smooth with Nameless+Kernel R17 and i changed my partitions to F2FS (is this a good idea?) so far no problems, othen than those 3 above.

Off late I am facing a wired issue.

I am losing partial internet access. Problem is very much similar like, if you have some issue with your DNS. Certain part of the internet becomes dark. However, rebooting the device solves the issue.

I often use my Z2 Plus hotpot feature, so there too, clients would have this issue. Rebooting the device resolve the issue both at device and clients level.

And no, putting the flight mode on and off doesn't solve the issue. I would need to reboot.

Thanks.

Hi Team,

I've tried installing AICP 13.1 in my z2 plus, but it failed with an error message

Yes, performance has taken a hit for last few weekly builds. UI lags occasionally, so are in apps performance. For gaming, PubG lags badly.

Switched to Nameless R17, lag is some what removed, but I am forced to stay in low settings.

Battery consumption is also high, overnight discharge is like 2.2-2.5% an hour. While PubG, it's around 35-40% per hour.

Only bright sight is the heat management, really good, never seen any ROM running as cool as this while playing PubG.

Bit disappointed since AiCP earlier 13.1 builds delivered some awesome performance previously

Hey any Update when will Android 9.0 comes to AICP ??
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] scott86:
Hopefully not for a long time. The aicp version of nougat was considerably more stable and better optimized when it switched to Oreo than the Oreo version is today. The dev should focus more on getting this one rock solid before moving to pie. To be honest I'd have prefered he stayed on nougat since none of the new features of Oreo(or pie, I presume) were worth the huge hit to stability, ui or battery life that we are currently dealing with on 13.1.

Hi I have been facing download issues lately with this rom.

Whenever I try to download a big file(500mb+) from browser or from playstore, more often then not, the download cancels out at after 85-90% download.

Any suggestions/fix?

This ROM isn't actually Weekly. I think the Developer or Saurce should make a Stable update once in a Month.

Team never Upload the Packages on time. :(

Ice cold project. <3
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] NaXal:
Well update history does show release more often than monthly for sure. They may be bit late, but usually update does arrive 10/12 days basis !!

At times it may be delayed due to devs own personal work but I think, that is fair enough.

However, I am 100% with you for the idea of stability over rushed update.

I used to have AiCP as my daily driver, ROM was smoothest, fastest, and trouble free when compared to other treble ROMs, but unfortunately with last few weekly, performance took a bit hit.

Keeping my fingers crossed that Dev may release next update, be it weekly or monthly and take back AiCP to its original glory !!

Yes it's slow. But after 2-3 charge may be it will starts charging fast.
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] NaXal:
It takes me around 35-40 mins for 20 to 80%. So that is around or just shy of 1.5% per min. This is via default given box charger. I have a QC 3.0 car charger in my car. That does 20-80% even faster (Haven't got the chance to time it yet). This is with AiCP default kernel or with nameless kernel, result is more or less similar.

I am not sure if this charging performance slow or fast but compare to other devices which my friends are using, I find this personally sufficient !!

Thanks.

[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] Shivamk845:
You should wait for future releases as you want Good Battery backup and High lag free Performance.

You may not get satisfaction with current builds there are lags because of newly added features which will surely get fixed after 2-3 builds. :)
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] priyanshu16:
Thanks for the suggestions :)

So in the future, I can download treble rom from this link right http://dwnld.aicp-rom.com/?device=z2_plus&type=WEEKLY

And is there any way of backing up aicp settings like you can in the Nova launcher and later loading it on in a new built?
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] Shivamk845:
Yes, if you have Rooted Phone then you can backup AICP launcher APK and it's data using titanium backup app. So you can restore the same.

But wait, if you backup the AICP Launcher and it's data on AICP February update and Restore it on August update then it will create Problems and may be get crashed.

In this case you can try restoring data only so it will get merged with Newest version too. ;)

TWRP ERROR 7 in this week's update

hi i am facing issue installing this weekly version. while flashing the rom with TWRP,which i downloaded form http://dwnld.aicp-rom.com/?device=z2_plus&type=WEEKLY , i am getting :

E1001 failed to update system image

Updater process ended with ERROR:7

Error installing zip file '/sdcard/aicp_z2_plus_o-13.1-WEEKLY-20180810.zip'

i googled the problem and found that deleting some 'assert' line form the updater script in META-com-google-android folder form rom fixes the issue.

but in the latest rom, there is no 'assert' line in updater file.

i tried wiping data cache and system through advance wipe and was able fix the unable to mount storage which i was previously getting, but not anymore(read it somewhere in forums).

what should i do to fix this assert issue/which line should i delete for the updater script.

halp :(
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] NaXal:
Error 7 I guess is due to Treble ROM setup issue.

Are you running a non treble ROM presently ??

Have a read here, you may need to prep the phone for treble ROMs before trying to install this version since AiCP 13.1 is a full treble ROM.
