Thanks for the information! I do not want to break anything so I would like to follow a more detailed 'tutorial'. I did search for some, but I am not sure which I can use to install this particular rom. Is there one you can recommend? Like somthing for beginners?

No flashing instructions for beginners are offered, sorry. If you're here in this section, you should know what you're doing. More detailed guide can be found here and here .
Read the instructions carefully and completely, check unfamiliar terminology by google or xda.
The instructions do not perform, if you do not know what you're doing.
P.S.: keep in mind, that this ROM is rooted with build-in SuperUser , and you cannot turn off SuperUser!

Okay thanks. I kinda know what I am doing, at least I know what I want. My last time is some years ago on samsung devices so I am not into the new phoes but I will read some and go for it.

Hi Alf! Is always me ahaha.
Anyway I wanted to ask you if it makes sense to switch from LineageOS 18.1 to this one here, or they are the same (especially in terms of stability). I also would like to know if there is a way to avoid loosing the unlocked bootloader when I have to switch to stock firmware. Thank you

is F21s Pro diffrent from F21 Pro? can you make TWRP flashable?

EDIT: I resolved this error by simply check a guide for SP Flash Tools. The required file was MTK_AllInOne_DA.bin
Thank you for the guide.
I'm stuck at point 3, when I try to flash the phone with SP Flash Tools, I need to add the Download-Agent file in order to proceed. I used all the .bin files in the rom folder but none of them work.
Could you please advise?
Thanks

Hi,
I successfully flashed the phone with the firmware LOS18.1-QJIN-F21PRO as the one attached failed during the flash process. My phone is the 3/32GB version.
I have two problems:
1) I tried to lock the bootloader (for security reason) but the phone never starter. (I imagine that cannot be possible)
2) The keypad light is always on, is there a way to turn it off while the screen is off? Which application/setting is controlling this function? I might be able to help
Overall the system is pretty stable, my next step is to install the MicroG. Any advice on this?
Thank you

f21s Pro is F21 Pro. it is the same thing.
TWRP brought in 4PDA (Thankful to @ Hagai that brought it in Mitamchim top - the Israeli forum). flash it as boot_a.
twrp.img
drive.google.com
What is LOS18.1-QJIN-F21PRO? This LOS for 32GB from 4PDA? It is based on my ROM.
You can not lock bootloader After Flashing ROM
Light in the keys? It's a well-known bug (number 4)
I now work on repairs, for example better support in hardware keypad.
​

Update: I managed to flash and access TWRP, but not able to find the MicroG zip file saved in the phone.
Hi,
Yes, I took the LOS18.1-QJIN-F21PRO from the 4PDA forum (I don't speak Russian).
I will try to flash microG through TWRP (thank you for providing it)
How would I access the TWRP on the F21pro? Is it sufficient to boot the phone with volume down (#/camera button) pressed?
Many thanks

is volte working in this rom? thanks a lot.

Instead of Gapps, MicroG would be awesome and less invasive (and easy to implement).
Please keep Lineageos clean and in the worst-case scenario, the user will install MicroG or Gapps separately.

ok.
i fix the bluetooth headset problem...
in the next version, w.g.h.

Can anyone confirm volte is working on v2? Thanks a lot

Code:
- Your warranty is now void.
- You have been warned.
- Use at your own risk.
Introduction:
This is the Official Lineage OS 18.1 thread for the Moto Z Play.
Downloads:
Please follow the install instructions in your device's Wiki page linked below exactly, and make sure your device's firmware matches the required firmware listed.
addison
If you don't follow these instructions, or use 3rd party add-ons (like Magisk) please don't expect support here.
Known Bugs:
The EQ Apps for Audio Mods (eg. JBL2 App) won't work, and will crash.
Audio Mods have no alarm or notification audio through them.
Camera Mods don't (and won't ever) work.
Volume may be lowered when locking and unlocking the device
Non-original touchscreens may fail to respond
Find any? Report them according to this guide.
Notes:
The only supported GApps package at the moment is MindTheGapps, linked on our Wiki page about gapps.
Official Lineage OS builds for addison ship with full Project Treble compatibility! Flash GSI's to your heart's content after flashing Lineage. Please don't report GSI bugs here, report them instead to the GSI's maker.
Code:
Technical details on our Treble implementation:
Treble is enabled with VNDK30, and VNDK runtime enforcement. VNDK runtime enforcement means that unlike most "ported treble" you'll see, ours is just as it would be from the OEM, and can run GSIs. without need for hacks or additional flashable zips. We relabeled /oem to /vendor (as /oem isn't wasn't used in custom ROMs anyway). To use a GSI, flash official Lineage, then flash your GSI, it's that simple! Flashing a factory image will likely write over /oem and remove the mock vendor image.

Hi there, just tried this new ROM and it is pretty nice that most functions are working well, really appreciate your maintainance!
However, this ROM has the same bugs as the previous AICP one does, like touching the fingerprint sensor would lead to immediate lock screens (could be fixed when deleted the fpc1020.kl file in vendor), and failing to read an adaptive Type C headphones bugs, hope they could be fixed later.

Yes, it does as it's based on the same trees
Also don't report the fact that pressing the fp will lock the screen as a bug, it's an intended feature, what's not intended is the fact that for some reason it can't be disabled right now

Sorry friend I posted here but I got very impatient and re-applied the rom and the front flash is ok. The only downside is that NFC is not working in practice, despite being available in the settings menu. Does anyone know or have the same bug?

First, thank you very much for the ROM @marcost22
I think it's amazing to bring an "updated" android to an old smartphone
Here I had the same problem with NFC (my variant is XT1635-03)
How I "solved":
restart in twrp (use latest that can mount vendor folder)
mount the vendor partition
Go to /vendor/etc folder
delete the file libnfc-nxp.conf
rename the file libnfc-nxp_retcn.conf to libnfc-nxp.conf
If you have magisk, it won't work.
You have to do this configuration before installing magisk.

Doogee N20 - Some phones are just hard to modify

After finally unlocking the bootloader, installed TWRP 3.6.0 and rotted with Magisk v23.0. Lets find a custom ROM that suits this phone - WRONG!
I have tried many types of ROM and so far it ends in soft brick. Need advise if you have any. My aim is to install a basic custom ROM , install pico or nano GAPP, and only install like 4 apps on it. phone, sms, navigation, music player etc.
I have tried the following ROM:
Phhusson-treble AOSP andriod version 9, 11 & 12.
GSI arm64 ab ROM
a so call stock ROM
I also tried installing the vendor.img as described here
I would like to use LineageOS but there doesn't seem to be one for this phone
I am now resorting to installing the stock firmware to make the phone work again, instruction here
If anyone has sucessfully rooted this phone using a basic ROM and GAPP please share how you did it and where your download was.

Why did phhuson fail ? That's the basic gsi, every other gsi are build on top of that. If that doesn't work, nothing will.

I install - system-arm64 –ab
I did some research that the Doogee n20 is a arm64 and a+b .... Unless I got the wrong information.
I suspect there maybe some stock firmware files that needs to be installed as well to make it work properly.
A post said it needs vendor.img, I might try sourcing another copy.
Follow up - I got it un-bricked with the stock firmware (android 9) (link in my original post) .... Back to square one .

Hey man, did you get it fixed?
Actually this device is A-only, but you should use Gsis A/B.
Most Phh based Gsi works almost perfectly for me.
You can try this:
- Download and install Twrp 3.6.1 here
- Download LineageOS 18.1 (lir) here Choose "arm64 bvZ" version
- Download stock rom here or Y9Plus variant here
- Extract the Gsi, and the vendor image from the stock rom
- I restarted in Twrp, go to wipe and select system, data, cache...
- Go install and flash the Gsi as system image, and vendor as vendor image
-reboot

With emui8 use only Netflix 6.26
With emui9 with safetynet ok, you can use the last version of Netflix 8

Now, Netflix 6.26 works.

Wow this worked! Thank you so much!!! It's breathed life into this older, but perfectly functional, tablet.
Does anyone have a guidance then can give me on how to set the kernel to 'permissive'?

PHH Treble settings >>Huawei Features >> Enable fingerprint gestures. this function doesnt work. turning it on or off doesnt allow using the implemented fingerprint gesture

Will this ROM work if I format data as f2fs?

Yes
