Mate 8 stock on emui 4 with no updates !

Hi there ,
I`m new in on this kind of stuff and i have 1 problem.
My device is Huawei mate 8 , and last week i unlock bootloader and rooted with magisk.
After that i flash the Kangvip [Custom Rom] Huawei Mate 8 - NXT-L29C432B582 -Custom System Update - ("V.6"), but did not have google play,when i try to unnistall some apps the settings close,fingerprint not working so i decide to send my device to service .
Before flashing the Kangvip i have Android 7 with emui 5.0.1.
When i pick up my device from service it came with android 6 and emui 4 and some bugs,themes dont work and i`m missing emui 5 with android 7.
I try to update via settings/update but no updates there, try with hicare but no rezults there .
So i`m stuck on emui 4.
Is there any way to go back on emui 5 ?

Its okayyy! My issue has been resolved lol i just had to dload a b330 firmware then the rest of the ota came flooding in ??
And I'm back again! Now with the aged old emui 5 problem, anyone found a way to disable auto dimming on chrome? Or forced it to run on Performance mode like we could back in emui 4? The chrome dimming doesn't really bother me too much but it happens in the middle of my Rules Of Survivor matches and starts lagging while dimmed. That's hella annoying ? really dont want all these effort of updating to emui 5 to go a waste n end up going back go 4.1 ??

How to get from nougat/Emui 5 to Pi?

So my phone is downloading L09C34B171, I just got it 2nd hand and unlocked the bootloader.
I've seen some conflicting things on using emui 8 or 9, I want to install a rom like lineage or RRv7 with magisk but apparently i need to flash everything from emui 8, so will my phone be updated to this before going to the emui 9.1?
thanks for any advice, keen to get some sweet custom OS so emui can go away.
I believe you need to have a phone on PIE to use RRv7. I flashed RRv7 to my Xiaomi Mi 8 lite and it's so much better than what was on it before. I just flashed PIE on my mate 9 yesterday and it's great. Read the thread below and you'll see how me and another guy did it. My bootloader is still unlocked so I imagine I can just flash twrp for PIE and then flash RRv7 which I'm thinking about doing. Not sure that I see that much difference is 8.0 and 9.0 but it runs fine.

Huawei 30p lite - Revert to EMUI 11 from EMUI 12

I searched a few hours in the internet to find a finite answer but there are so many old threads and old Youtube videos with dead links so I'm not really sure if there is a way or not.
A friend of mine has an Huawei p30 lite and wants to revert the last update back to the previous version of EMUI 11 instead of EMUI 12.
The phone is still on stock - no open bootloader, no root, nothing.
Is there any way to revert the last update back to Version 12 - best case without bootloader unlocking tools just be placing an older version of the firmware somewhere?
Sorry if this has been asked countless times but as I said I always only found dead links.
Thank you very much.
