Team Win Recovery Project 3.x, or twrp3 for short, is a custom recovery built with ease of use and customization in mind. Its a fully touch driven user interface no more volume rocker or power buttons to mash. The GUI is also fully XML driven and completely theme-able. You can change just about every aspect of the look and feel.

Code:
 * Your warranty is now void.
* I am not responsible for bricked devices, dead SD cards,
* thermonuclear war, or your getting fired because the alarm app failed. Please
* do some research if you have any concerns about features included in this ROM
* before flashing it! YOU are choosing to make these modifications, and if
* you point the finger at me for messing up your device, I will laugh at you.

Supported Models:
Galaxy A71 SM-A715F, SM-A715U, SM-A715U1, SM-A715V and SM-A715W.

US/Canada bootloader unlock thread:

Download & Guide:
1. Unlock your bootloader.
2. Download A71: a71.
3. Reboot to download mode and flash vbmeta_disabled.tar in AP slot and reboot. Device will reboot to stock recovery mode prompting you to wipe data so wipe data and reboot to download mode again.
4. Put the TWRP tar for your device with Odin in the AP slot and click start.
5. Reboot to recovery via recovery key combo.
6. Disable encryption:
Or:
- Go to Advanced > Terminal, type: multidisabler.​
If vendor complain about free space left on device, will attempt to resize vendor. and it ask to - Run multidisabler again!.​
- Type: multidisabler again. will see - Finished. when done.​
7. Go back to Wipe > Format Data > type yes.
8. Reboot to recovery.
9. Flash magisk apk in twrp.
10. Reboot to system, Enjoy.

Note:
To disable encryption manually:
You need to replace fileencryption=ice with encryptable=ice only in userdata line (maybe rest lines) in vendor/etc/fstab.qcom
To avoid stock recovery restoration manually:
Rename system/recovery-from-boot.p to recovery-from-boot.p.bak

I bought another a71 mainboard and the problem is still same. finger print need calibration. is that software or hardware problem ? finger print work well before unlock bootloader
I think disabling encryption broke it. This doesn't effect US devices only international variants on specific models.

I cant help you now, as I said above still working on it. dont spam the thread.
Can you help me with something?
I have the TWRP 3.5.1 [ianmacd] recovery installed and a custom Samsung ROM (NcX 3.1.2).
I want to flash the stock firmware via odin to keep the ROM up to date (though without losing data, by flashing the HOME_CSC file).
I'll need to flash TWRP again to install Magisk and Root later via Odin as even though it wont format my data, it will flash on top of my current TWRP.

To install yours, what steps should i follow after i flash the Stock ROM again? (Remember that i wont lose data/need to encrypt the phone again)?

There is 90% chance to lose data, make data backup move it to PC then try.
Note1: changing vbmeta will lose data so must flash same file.
Note2: if you disabled encryption need to do again.
Ignoring note 1&2 then rebooting to system will lose data
