Best ROM to flash on EVA-L09 ?

Hello guys, I bought my Huawei P9 back in December 2016 and since then I only used official EMUI 4.1, official EMUI 5.0 and I am currently using the NewWorld-7 by Tecalote, but I am now looking to change this.
I need you guys to suggest me the "best" if I can say ROM out there for the P9, kinda doesn't matter the version. Only a few notes: The ROM must have a working Camera, GPS, Fingerprint, Bluetooth, etc. (as much things working as possible).
Because I want the ROM to have as less bugs as possible I am thinking of installing the official ROM, probably B378 (or whatever the latest version was), but I want to keep my root access on the other hand, so I'm also thinking about dkionline's "mOOnlight ROM v1.0 B378 Stock", but the thing is that as far as I'm concerned, on Custom ROMs, the PlayStore isn't updating and this is important for me, because I am modding my games a lot and the latest version of the PlayStore is required.
One thing in EMUI 5 that I hate is the lockscreen when using Spotify. I have no problem about the thing being small (in EMUI 4 it takes the whole screen), but atleast the controls to be working properly (people who used Spotify and B362 or whatever the first official B3XX build was will undestand).
So well, suggest me what ROM to install

How to update a friend's P9 from 6.0 to 7.0 and root it

Hey all,
So my friend currently has a P9. He's wanting to update from 6.0 to 7.0 (or the latest available stock version for his phone) and then root it. I've no experience with Huawei phones, I'm an LG guy. What would be the best way for him to do this?
His device information is:
Region - Australia
Model - EVA-L09 Huawei P9
Build Number - EVA-L09C346B195
EMUI 4.1.3 on Android 6.0
September 5th security patch level, kernel built on Mon Sep 4
I've read about downloading the 7.0 update and putting it on his phone and doing the local update but I'm unsure where to get the update files needed or what version, etc. It's his work phone so he'd prefer the latest available stock 7.0 version. Then, how do we go about the best way to root it for him?
Thanks a ton to anyone able to help!

P9+Android6+EMUI 4.1+fRomFutureNewWorld V4 - upgrade to Android7/8

Hi guys
A year and the half or even better just after I purchased my P9 I unlocked bootloader, rooted and went for custom ROM (fRomFuture - NewWorld V4) the only one available and 100% working for P9 at that time as I remember. I got this system since then and I must admit it works pretty well surprisingly without any updates. However I just received work smartphone (Moto G5) which supports dual-sim and realize this is good moment for upgrade my P9. I just took read P9 7.x/8.x ROM's flashing installation descriptions and I feel dizzy....upgrading EMUI, changing partition type from FAT to encrypted ext4..... uff... I already flashed my P9 with custom ROM but back then it seems much much easy with Android 6.
First of all how could I check my firmware version ? With NewWorld ROM I don't see this kind of info.
Second - from what I read I need to update EMUI first from 4.1 to newest ,correct ? Do I need to know my firmware version for that or upgrade could be done (on already flashed system) via Huawei official software ?
I'd like to go for [ROM][8.1][OpenKirin's RROS Oreo v6.0.0 for instance. On Moto G5 I have to install 64bit TWRP and ARM64 Gapps as well - is this the same story with Huawei ?
Make this story short - what step should I take to upgrade my unlocked,rooted P9-EVA with Android 6,TWRP and NewWorld ROM to something newer like even Android 7.x but prefer 8.x because it seems to be working much faster than 7 on my Motorola.
Thanks for help and sorry for lame questions

Flash stock firmware using dload, update to the latest firmware then flash the custom rom you want.

thinking of buying p9, noob questions.

Hello I have been a lifelong xperia z compact fan, but due to the the awesome camera on the p9 and its similar screen size I am thinking of switching Have some questions that are not clear atm.
- I am used to rooting but it seems that on p9 rooting is only possible with android 6? if i buy a second hand phone with android 8 it is possible to downgrade and root? from what i have read about the p10 it is not possible.
- I noticed that the latest custom EMUI roms are android 7, Is there a big emui interface upgrade with android 8? I am primarly intersted in the camera, with the android 8 is there an improvement in camera quality/camera interface? Do people prefer older versions (6) for battery life or camera quality?
- Someone made the point that these days rooting is less usefull apart from tinkering, the only reason is a proper adblocker, do many users here decide that the latest 8.0 version is worth it over rooting?
- Do any lineage/aosp etc roms have huawei camera ported?
thank you

- Rooting by SuperSU is possible also with Nougat - but SuperSU is no more updated and bacame obsolete nowadays.
Rooting by Magisk is possible with Nougat and Oreo.
Not sure about Marshmallow but Nougat and Oreo definitely cannot be rooted by King(o)Root or so
- If not stuck with the wrong cust, your P9 should be already updated to Nougat (EMUI 5) - even if stuck with, you can rebrand and then upgrade by OTA to the latest stock Nougat.
Only for Chinese cust, P9 will be updated to Oreo (EMUI 8) - but you can also rebrand to and enjoy AL10 c00 Oreo (latest b540 OTA Patch02), with easy modifications it becomes fully 'internetional' (with all languages, Playstore, ready for Google Assistant, international 3G/4G bands, etc) and you can additionally patch Face Unlock (not supported by stock Chinese Oreo, neither by OpenKirin custom ROMs - see further below):
https://forum.xda-developers.com/p9/development/rebrand-update-tool-hwota7-p9-eva-t3820849
- For rebranding and/or rooting you must unlock Bootloader. Code cannot be obtained (and for free) from Huawei anymore, but can be purchased for 4-5 Euros from Ministry of Solutions or DC Unlocker:
https://ministryofsolutions.com/paid-services/amp
https://www.dc-unlocker.com/DC-Phoenix-flash-repair-tutorial
- There are OpenKirin Treble ROMs based on LineageOS, ResurrectionRemix and Omni Oreo or even Pie - installation requires first to (rebrand and) update to stock Oreo:
https://forum.xda-developers.com/p9/development/roms-openkirin-aosp-collection-t3828806
- Besides the AdAway root app and e.g. Magisk module YouTube Vanced, Magisk might be needed or useful if you rebrand and update to Chinese Oreo.
Namely, you must keep the Bootloader unlocked which blocks SafetyNet (and consequently e.g. GPay - not sure if GPay and NFC are supported and by which OpenKirin ROM, it also changes with their updates).
Hence, Magisk hides the unlocked Bootloader, device shows as certified and passes SafetyNet, and you can use GPay on the rebranded and patched EMUI Oreo.
- With (rebranded) stock Oreo, battery is actually better than with stock Nougat.
Cannot tell you about Marshmallow (used ir only short and long ago).
AFAIK, stock Camera with all its features is not (fully) supported by OpenKirin ROMs (used and tested only one of them for a day or two, and few months ago)
PS: If buying a new P9, you can think of dual SIM L19/L29 - but be aware, unlike single SIM L09, dual SIM lacks NFC reader.
Or even about bigger display P9 Plus - all about rebranding, patched Chinese Oreo, OpenKirin ROMs, etc, also applies to:
https://forum.xda-developers.com/p9-plus/development/rebrand-update-tool-hwota7-p9-plus-vie-t3843930

I recommend getting a P10 instead. But if you can get it for really cheap, the P9 is a very high value phone. Buy phone. Buy DC Unlocker credits. Unlock. Rebrand. Update. Patch. Enjoy Treble and Android O/P.

Thank you so much for the replies guys, yes after doing some more research will buy a p10 second hand, it has a headphone jack, compact screen and great camera very hard to find! unf i read that after a recent firmware update it is now impossible to unlock bootloader from unlockbootloader site .

Be careful (if you plan to do rooting/modding), for some newer Huawei phones, already coming with Android 8 or 9, it is no more possible to unlock Bootloader for free or for 4-5 Euros but only for 30 Euros
And this is not about 'missing that phone from the bootloader codes site, but due to the fact that Huawei switched for them (during the last 6-9 months) to the new and different Bootloader
It might be also questionable what kind of modding is possible at the moment on some of the newest phones with newest firmwares
Not sure does this new Bootloader apply to P10, and does that new Bootloader come by OTA to old P10 phones (better check here on XDA but on the P10 forum)
However, P9 phones do not come and do not get OTA updated with that new Bootloader (even if you rebrand to Chinese Oreo and get its OTA updates), Bootloader code can be bought for 4-5 Euros and modding (incl. rebranding, rooting, etc is possible)

Custom Rom on Huawei p9 EVA-L09

Hello everyone, I have a huawei p9 EVA-L09 branded (TIM, I come from Italy).. Is it possible to install a custom ROM, better if pixel experience? has android 7.0 and EMUI 5.0.3. Thank you!

First of all, to flash anything (root,TWRP, custom ROMs) you must unlock Bootloader
Second, check the threads in ROMs section but if I recall correctly for P9, EMUI 5, there were only two or three custom ROMs based on stock and one or two (LOS and maybe RR) based on AOSP - developed (and stopped) back in 2017
EMUI 5 was not ready for GSI ROMs, and every custom ROM must have been adapted and ported to P9
You probably think about new, GSI based Pixel Experience or similar ROMs - for that you would first need to update to EMUI 8, Oreo (and rebrand from your Italian to Chinese EMUI because EMUI 8 was only released for China)
All together not impossible but not as easy and friendly as if you would have a new (Android 9 or 10) Xiaomi, One Plus or a similar phone where you just unlock Bootloader and start experimenting with GSI ROMs
Last but not the least, specially if you are a newbie, think about the community regarding help, learning from, sharing experience - there are only two or three users who are still actively experimenting with GSI/AOSP custom ROMs on P9, posting only something from month to month here, hence you will mostly need to go alone

If your device is unlocked, rebranded and updated to EMUI 8.0, you can install GSI ROMs with some issues. You're better off installing OpenKirin ROMs or sticking to EMUI 8.0. This device isn't very active in development, but we will try to help. You can install phh-based Android O/P ROMs. Android Q GSIs don't work because of this device's VNDK 26.
