[Guide/Workaround] Fingerprint Enrollment

** NOTE **
Files you are going to copy/create by this guide, contain your fingerprint. Do not share them with anyone, also keep them at safe place. No one will be responsible other than you!
What exactly this guide will do ?
It will copy FP data from previous working ROM and paste in current ROM where FP enrollment does not work. In short we are bypassing FP enrollment process to eliminate enrollment error.
We are going to backuo FP data, which is stored at /data/system/users.
Important News: Recently we found, FP Enrollment Error in "O" is ROM related and doesn't require O-Modem, it will get solved soon. Use this method until it get solved.
My little Assumption for not requirement of O-modem is: there is no big difference between N and O, N-modem is compatible with O and that's the reason we don't need O-modem for O-ROMs. Source: rovo89 said same for xposed.
I will keep this workaround here for future android updates with large change.
Let's start bypassing enrollment process...
** Requirements **
- Any N-ROM (Stock/Custom doesn't matter)
- Root Manager: SuperSU / Magisk (if ROM is not preRooted)
- ZipMe for creating flashable zip (take APK after installation), Play Store Link : ZipMe
** GUIDE **
- if O-ROM is installed (Take backup, in TWRP)
- Clean install N ROM (and ROOT it.) (Gapps not needed, if you got apk of ZipMe)
- boot it
- go to, > Settings > security > add security of your choice and add 5 FPs (choose 5 spots of your fingers carefully, once you installed them in O-ROM, you will not be able to edit them, only delete is possible)
- open ZipMe, tap "+" (at bottom) then select folder
- go to, > data > system > users [ tap select]
- you will see "users" folder is added to main screen, then tap "create" (bottom bar) (choose your preferred directory and zip name.)
Now you have successfully got backup zip of FPs.
Now, moving to O-ROM.
- Restore O-ROM backup if made otherwise flash ROM, Gapps and other Mods but don't flash FP zip now
- boot ROM
- go to, > Settings > security > add your preferred security lock (dont add FP, it will only give error)
- reboot to recovery
- flash FP zip
- reboot to system
- congratulations, now you can unlock with FP.
** Points to remember **
* Don't share FP zip / keep it private.
* Flashing in recovery is necessary, as we can't replace those files while system is running (TWRP recovery file manager works for copy&paste, but i haven't mentioned because it will be hard for many one)
* If you delete any FP accidentally, you can flash FP zip instantly, Clean flash or Restore of any backup is not needed.
* If you need to change FPs, then only you have to go through all steps.. otherwise for same FPs, you can use same FP zip for any O-ROM / Future updates / Clean Installation. (So, it is one time procedure to get FP zip, then forget everything )

I have no Idea what are you talking about!?!
what does it do?

The actual test builds of Oreo have problems with fp enrollment hence his workaround makes you able to use fp with Oreo by copying your registered fp with nougat over to Oreo.

I'm not very sure but normally yes...
I have try only in M3K1 but Is the same device generally (MT6797D 64 gb Internal 4gb ram android 8 + playstore)
better try via fastboot
the decision is yours

@jefferyli:
Did you try to install it on the M3K4 device? Was it successfull?
@daitalos:
In terms of stability do you recommend AOSP 8.1 over AOSP 9.0?

aosp 8.1 was more stable,but after the latest update (build v112) aosp 9 works very well
we are expecting and new update of aosp 9 these days....So,if you want to install it is better to wait for the newest build I think ...
LOL... There is new build aosp 9 V113 : https://github.com/phhusson/treble_experimentations/releases/tag/v113
aosp 8.1 build V31 : https://github.com/phhusson/treble_experimentations/releases/tag/v31

What is better about this ROM than the Stock ROM?

....this depends on what custom rom you are talking about & your device model - stock rom
some advantages of aosp phh 8.1 (or 9) from teclast M20_4G stock rom
stock rom on M20_4G is android oreo 8 - without updates & support anymore
this aosp phh is oreo 8.1 (or newer-latest android pie9)
security : stock firmware has sec patch 2018 - this 8.1 (or pie9) gets monthly updates (bug fixes + sec patch 2019)
features : this aosp phh is pure stock android
& more like as : root access,better performance,battery management etc...

Edit: It worked with Magisk 18.1

Please make it for realmeui too.

Can someone post some benchmarks from their devices pre and post successful transition to F2FS?

[GSI][PHH][Q][R][S] GSI flashing for Realme C12

Before doing anything to device, keep a copy of Stock ROM from here in your PC or SD Card.
Installing GSI ROMs
Tutorial:
If you don't know what a GSI is or want to know more about it, see this, this and this
Don't try to flash GSI in custom recovery.​
Note:- We can only flash GSIs having android version higher than or equal to stock rom android version. That is if your StockROM Android version is 10, then you can only flash GSIs of Android 10 or higher.
If you are flashing GSI with custom ROM installed, then flash stock ROM before flashing GSI. Since boot and vendor(may), get modified with custom ROM.
Step 1 - Pick your poison in the Treble Forums or from here!
Check below of this thread if you want to see my recommendations with links to them.
Step 2 - Download the chosen ROM, A/B ARM64 version (usually nicknamed (b), with (g) or without GApps (v), rooted (S) or not (N), that's entirely up to you.
It should be an .img.xz file, extract it and you'll get an .img file.​
For example, I am downloading this​
You're ready to flash. Make sure to backup your phone's data before continuing on with this tutorial, as wiping it is required for installation!
Step 3 - Put your phone into fastboot mode (Power + Volume Down) and link it to your PC.
Step 4 - Move the .img file and vbmeta.img you downloaded to your ADB & Fastboot (Platform Tools) folder, and rename it to system.img.
Step 5 - Shift + Right click in an empty space inside the folder, and click Open Command window here.
Inside the Command window, input the following commands line by line, in order.​
Code:
fastboot reboot fastboot // Recovery will appear with fastbootd mode
fastboot flash system system.img
fastboot reboot bootloader
fastboot --disable-verity --disable-verification flash vbmeta vbmeta.img
fastboot -w // Skip this if you are updating GSI
fastboot reboot
Your phone will now reboot on its own, using the new ROM you picked earlier, set it all up and enjoy!
GSI bugs without having any possible fixes
These bugs are there in my device and I can't able to fix them
DoubleTapToWake with Q vendor
Lift to wake with R vendor
Fingerpirnt(egis) with R vendor
GSI bugs and possible fixes
VoLTE is fixed in Android 11(R) GSIs which are based on AOSP v300j for Q vendor and AOSP v312 for R vendor
we can get VoLTE working by following below
- Goto Settings => Phh Treble Settings => IMS features
- Now Select both Request IMS network && Force the presence of 4G Calling
- Now click Install IMS APK for Mediatek Q vendor.
- Let it complete download (check your notification panel).
It will show IMS installed You may now reboot! as a toast message
- Now click Create IMS APN (Nothing will happen)
- Reboot and Enjoy!

Fix wired ear phones not working
- Go to Settings => Phh Treble Settings => Misc features
- Check Use alternative way to detect headsets
- Reboot
Fix Bluetooth speakers/earphones not working (not tested because I don't have these)

- Check Force-disable A2DP offload
- Reboot
Enable USB OTG
- Go to Settings => Phh Treble Settings => Oppo features

If there is no Oppo features in settings then simply run below command in Termux
Code:
su -c "setprop persist.sys.phh.oppo.usbotg 1"
/system partition is read-only
this is the default behaviour of non-vndklite GSIs from v300.j onwards, to get R/W access for /system use vndklite variant.

FAQ
I can't able to use Magisk because of inbuilt phh SuperUser
- To use Magisk, we have to remove inbuilt phh SuperUser first, to do so boot to TWRP and run below commands in PC
Code:
adb shell
mount /system_root
mount -o rw,remount /system_root
rm -rf /system_root/system/app/me.phh.superuser
rm -f /system_root/system/bin/phh-su
rm -f /system_root/system/etc/init/su.rc
rm -f /system_root/system/xbin/su
exit
Now you can able to use Magisk
I can't able to install GApps in vanilla variant
- Simple thing we have to do is to use GApps variant of GSI. If you don't want to use GApps variant for some reason or there is no such thing at all, we need to resize system to increase free space in /system partition. For this we need to use fastbootd mode
Code:
adb reboot fastboot // or fastboot reboot fastboot if your are in fastboot mode
fastboot resize-logical-partition system 4294967296 // 4 GiB
fastboot reboot recovery
Now you can flash GApps package
If your are using UI 2.0 (means R vendor), then you may can't resize system 4 GiB as shown above, to do so we have to remove some unnecessary partitions first, run these commands in PC
Code:
adb reboot fastboot // or fastboot reboot fastboot if your are in fastboot mode
fastboot erase my_heytap
fastboot resize-logical-partition my_heytap 4096
fastboot erase my_stock
fastboot resize-logical-partition my_stock 4096
fastboot erase my_preload
fastboot resize-logical-partition my_preload 4096
Note that instead of deleting those partitions I erased and resized to 4KiB because deleting will cause longer booting time.

I am just testing AOSP v313 vndklite vanilla to create an overlay for fixing battery stats, status bar height and to set notch cutout.
Overlay made so far is attached below.
To make the overlay work, just place it in /system/product/overlay/and reboot. See if status bar height is increased or not and after some usage battery stats will appear (Setting -> Battery -> 3-dot -> Battery usage). We can check if overlay is applied or not using below commands in Termux su -c "lsof | grep treble-overlay-realme-c12" it will output some lines if successfully applied.
