Hi! I installed 3.5.0.0 twrp recovery with odin. My phone is SM-A705FN. It has SEK CSC coded firmware with OneUI 2.5. When the phone restarts, it warns you that it has modified software, press the power key. After a red message bets that the firmware is not genuine.
Can you get rid of these warnings?
After installing the recovery, Samsung Health does not start saying the device is rooted even though it is not rooted.

I opened the bootloader, restarted the phone in (OEM unlock) download mode, browsed the twrp recovery img.tar file with Odin. I flashed it into the phone. I restarted. That's all I did.

According to these, I have to do the following:
1. I enable developer mode on my phone.
2 . In developer mode, I turn on OEM unlock, then the phone restarts and does a factory reset.
3. I restart the phone in download mode, hold down the volume up button, then the OEM unlock will be complete, the phone will restart and format the / data partition
4. I restart the phone in download mode again, in ODIN on the AP tab I browse to the twrp.img.tar file. I remove the check mark from the restart option. I press and hold the volume down button for 7 seconds, restart the phone in recovery mode.
5. In TWRP I make the system partition writable and then reboot in download mode, with ODIN on the AP tab I browse the vbmeta.tar file and start flashing. In principle, TWRP is now permanently left in the phone.

It works like this? Will Samsung apps not see the phone as rooted?

no, after step 4, you need to reboot back to download mode- DO NOT reboot to recovery, flash vbmeta and in step 5, in twrp you need to flash disable force encryption then format data. use magisk hide to hide root from apps. you can also pack twrp and vbmeta together so youll only have to flash once in download mode.

edit: after more review of these steps, its missing a lot so here this should help:

Do I understand correctly? Should I compress TWRP recovery.img and vbmeta.img into a single .tar file, say, with PeaZip and ODIN browsing the AP tab, and flash it to my phone?

Yes because it saves you from having to reboot to download mode and flash twice and to ensure that vbmeta is flashed to the device but either way will work. Name the tar file Recovery.tar

Everything worked, recovery and rooting as well. But sjanos encountered a very unpleasant problem. After rotation, the phone will randomly restart. The magisk hide option is enabled, safety net is fixed, installed.

Yeah from my understanding, safety net wont pass due to selinux, bootloader unlock and root. So any modifications to safety net would trigger issues. The only way around it that i have found is to register your devices google framework id with google, here is the link, make sure your signed into your google account. You can also get your id easier by using the app "device info" from the play store.

This might sound a little off-topic, but im assured it's not.

Working Android Q With TWRP & Safteynet pass , also nandroid backups fully decryption (yes nandroid backups are working) Magisk and modules attached.
2 Satynet checks. I had to flash vbmeta used in android pie. (successful backup)
I'm using Magisk as per view..

Now, the importance is DO NOT USE "BASIC* attesst module or change prop values, although the current device is sn old A70 , will be getting Ultra 2morrow before going to Pixel.

Be inspired, but most of all, get that darn thing fixed.

    The CPU temp path on the A70 should be /sys/devices/virtual/thermal/thermal_zone18/temp.
