Hello friends, I'm in ViperOS Viper-z2_plus-20181118-v5.0-OFFICIAL which is No Treble. I want to update to Android 9, flashing ViperOS v6.3, someone can tell me a brief tutorial to do it, since I did the following thing:
1. Wipe data, system, dalvik and cache
2. flash factory to vendor of this thread: https://forum.xda-developers.com/lenovo-zuk-z2/how-to/z2plus-treble-roms-flashing-reverting-t3778287
3. With the official twrp flash image (selecting recovery) recovery treble of this thread: https://forum.xda-developers.com/lenovo-zuk-z2/how-to/z2plus-treble-roms-flashing-reverting- t3778287
(z2_plus_treble-TWRP-3.2.2_kubersharma_v2.img)
3. Flash rom and at the end I get this error: updater process ended with error 7. and above this puts E2001: failed to update vendor image
Here,
First you need a vendor mounted as factory.
Find required files here https://forum.xda-developers.com/lenovo-zuk-z2/how-to/z2plus-treble-roms-flashing-reverting-t3778287

Flash latest twrp from above thread and you're good to go! :)

Dev, rom is good, thank you. I saw some small glitches with default launcher, when swiping left to right and vice versa sometimes notification (qs) pannel comes down, and search in app drawer doesnt find any app. First thing I solved by disableing swype down for qs pannel in launcher settings. Second one is not so important, just wanted to give my feedback.

Still have to test battery etc...

Thanks

Not sure if you figured this out yet, but if you did not, here is what you need to do.

Most of the roms today are changing back to /factory instead of /vendor. Since it looks like you flashed factory2vendor, you are going to have to undo that by flashing vendor2factory.

Here are the steps:

1. Flash Vendor2factory zip
( https://www.androidfilehost.com/?fid=962187416754475514 )
2. Flash new TWRP with /factory support
It will work for both non treble roms like zui , and treble roms having /factory instead of vendor. You can flash the one from the link below or go flash the newest 3.3.0 version from here https://dl.twrp.me/z2_plus/
( https://www.androidfilehost.com/?fid...63190603913223 )
3. IMPORTANT STEP : Reboot to new TWRP
4 Flash rom
5. Flash gapps
6. Reboot system

Has anyone tried running 'PhonePe'? Currently I'm on AEX 6, 'GPay' is working fine but phone pe shows security error.

Thanks
You are asking AEX related question in Viper thread !

Anyways, Install magisk and then hide phone pe and Google pay in magisk. Then disable telephone permission of Google Play services.
Both will work.

Are you still using this ROM? If yes please provide me a review. About performance, gaming, thermal, battery backt etc :). Also, battery usage stats would be nice

Yes still using Viper rom, I haven't upgrade GPU drivers u mentioned, still performance is good.only heating issue,I'm playing pubg smooth medium settings game laggs after 10minutes bcz of heat (45+ in low 53+ medium/high settings).battery drains fast when phone heats.
Browsing, watching YouTube temps goes around 40-45 like normal usage.battery backup is good for daily apps like fb,YouTube, browsing.ram management is good also (u get 2 GB free ram) SOT 3 hrs.
This is my 1st custom rom I'm using and I'm happy with it.hope devs fix heat issue soon.
I told what I know hope it helps :)

I see, I'd really suggest you to try those GPU driver's. One thing they surely do is reduce heat during games. my device used to past 53° on my smooth/extreme settings in pubg. Post flashing these drivers, it was 47-49.
Thanks for the review anyway :)

I flashed latest version today. I was impressed. Boot time is so much less now and heating is negligible to what I've faced on other treble and non treble roms during initial Boot. Performance and app launch times are great so far as expected. I'll test fo few days and report Dev.
Thanks for work and time man :)

Dev, I'm facing very weird issue. At times multi touch gets registered, but often my other fingers don't get registered until I take off my first finger away. Is anyone else facing this? Is this kernel specific? Cuz I've got my front glass replaced.
