First I have a question: If I make a backup with TWRP beforehand, I can just back up everything but not "Super". What do I have to back up so that I can restore everything to 100%.

I inserted the SD card from my old Samsung into the A71. It works perfectly with all data, but the zip funktion is not ok and something is wrong with flashing. I have checked the card several times on the PC with test programs, everything OK, but I have ordered a new better one. I think that is where the fault is to be found. I'll be in touch when I have the new card and a result.

Greeting
Norbert

Try to redownload the ROM too, maybe the Zip file is corrupted.
About backup, well basicly Super partition (system partitions) and the Data partition. But i would backup EVERYTHING except cache

So, I inserted the new 64GB SD card. The first thing that strikes me, is that the device no longer demands formarting.
The zip file saved = works, flashed = works immediately the first time. Then Magisk-v22-1 (.zip) = does not work. Everything new again and flashed with Magisk-v22-0 (zip + apk) = works perfectly. Then the rest and then ....... ROOT RIGHTS !!! But you mustn't update to Magisk-v22-1 (.zip), then root is gone.
The original Samsung SD card from the Note4 still works in the Note4. But when I put it in the desktop PC, the error message "Zip archive incomplete" appears and the message "format SD card" appears in the A715F.
So ... I'm throwing these away.

I have created a detailed .pdf manual, but in "German". If after a few days everything still works and it's of interest, I can post them here.

Many, many thanks for all your support and I hope everything else works too.

In download mode you have to confirm the unlocking of the bootloader by long pressing the volume up button after you have activated the setting in the developer options. Then when you restart your phone, this setting should be gray and you can no longer change or tap it. Then the bootloader is unlocked

After confirming with volume up , I restart the phone and confirm that the OEM unlock cannot be changed and then I go to ODIN?

After install twrp by ODIN, and format data, i don't have anymore my internal storage then can't install multidisabler, guess should install by sd card correct? But, when i format data, i lose my TWRP, i can't open again TWRP after format data and reboot.

I'm stuck with my TWRP installed without format DATA, let alone with multidisabler installed, and everytime i try to install anything on TWRP i only see encrypted folders.

HELPPP WHAT DID I GO WRONG PLEASE ANSWER ME

When I flash and boot into TWRP, my internal storage appears to be encrypted (folders have random strings of characters as names) and I can't find and flash the multidisabler. After formatting data and rebooting I'm taken to the first-time android setup and if I reboot back into recovery mode TWRP has reverted back to the stock recovery. I've installed and reinstalled it like 10 times now and no dice. I assume multidisabler is what's supposed to stop it from reverting? Can anyone help me with this?

Yes, after formating you should flash multidisabler.

    Team Win Recovery Project is a custom recovery for Android devices.
    It allows you to back up and restore your data, flash custom ROMs to your device, repair broken file systems, root your device and more.

    Disclaimer:
    - I do not claim this work as my own, this thread was created to have an XDA thread for A71 TWRP. I will try my best to keep it up to date with Ian's work, but can't promise that will remain for ever. If you want the latest TWRP and to be notified as soon as its published, be sure to join the Telegram channel.

    - Please read the whole main post & related ones before proceed and follow the guide as it is wrote. I will not offer support for any issues that have been already stated.
    - Your Knox Warranty Bit will be blown once you flash this or others custom binaries, preventing you to use Knox Features. It can't be resetted in any way, so think twice before flashing this.
    - Bugs can be reported here in XDA or via our Telegram Group. Please be more clear as possible and make sure you provide detailed info when reporting bugs (device variant and logcat).

    How to Install:
    First, you need to unlock the bootloader. Here's how to do it:
    1. - Backup all media before proceeding, this will erase everything in your internal storage including music and photos
    2. - Go to developer settings and enable [OEM Unlock]
    3. - Reboot to download mode
    4. - When prompted, press and hold VOL + to enter bootloader unlock mode
    5. - Press VOL + to confirm you want to unlock bootloader, this will wipe your data
    6. - If you think the bootloader is fully unlocked, it is actually not! Samsung introduced VaultKeeper, meaning the bootloader will still reject any unofficial partitions before VaultKeeper explicitly allows it.
    7. - Go through the initial setup. Skip through all the steps since data will be wiped again later when we flash TWRP and magisk
    8. - Enable developer options, and confirm that the OEM unlocking option exists and is grayed out. This means the VaultKeeper service has unleashed the bootloader. This step is MANDATORY
    9. - Your bootloader now accepts unofficial images in download mode.

    After finally unlocking the bootloader, proceed with installing TWRP (tar) with Odin:
    1. - Boot to download mode and load TWRP tar file and VBMeta disabler tar file in AP and BL of Odin, doesn't matter which goes where
    2. - Disable [Auto Reboot] in Odin
    3. - Flash
    4. - Force a reboot by pressing VOL+, VOL - and POWER buttons at the same time
    5. - After the screen goes black, IMMEDIATELY let go of all buttons and IMMEDIATELY press and hold VOL+ and POWER button at the same time to boot to TWRP
    6. - After booting to TWRP successfully, go to WIPE in TWRP
    7. - At the bottom, you should see an option to FORMAT DATA. After you select it, you will be asked to type "yes" in your keyboard. If you do not see this, you probably selected the wrong option.
    8. - After formatting data, flash the Multidisabler zip with TWRP. This is done to avoid future bootloops.
    9. (Optional) Flash magisk.zip to root (google where to find it)
    10. - Reboot to system
    11. - Wait patiently for the device to boot for the first time


    How to flash TWRP (img):
    1. - Reboot to recovery
    2. - Select Install
    3. - Select Install Image and search for the TWRP img file
    4. - Flash as recovery
    5. - Reboot to recovery
    6. - Done
