What's knox ? : https://www.google.com/search?q=samsung+knox+explained

-Download the latest stock firmware for your Samsung Galaxy A70 with Samfirm/Frija app (faster) or Samfrew/Sammobile website (way slower).


https://samfrew.com/model/SM-A705FN/
https://samfrew.com/model/SM-A705F/
https://samfrew.com/model/SM-A705GM
https://samfrew.com/model/SM-A705MN
https://samfrew.com/model/SM-A705YN
https://samfrew.com/model/SM-A705U
https://samfrew.com/model/SM-A7050
https://samfrew.com/model/SM-A705W


-Extract the SM-A705XX_1_EXAMPLE_0000000000_fac.zip file with 7zip or any other unzipper.

-Copy the (AP_A705XXXXU5XXXX_CL00000000_QB00000000_REV00_user_low_ship_MULTI_CERT_meta_OS10.tar.md5) file and transfer it to your internal storage.

-Download and install Magisk Manager APK https://github.com/topjohnwu/Magisk/releases/download/manager-v7.5.1/MagiskManager-v7.5.1.apk

-Open Magisk Manager and go to Install > Install > Select and Patch a file.

-Navigate through the storage and select the extracted AP file.
The firmware will be patched and will be found in Internal Storage/Download/magisk_patched.tar.

-Transfer the patched file to your PC.

-Turn OFF your device and boot into DOWNLOAD MODE.

-In Odin, click on AP and select the patched tar file, Uncheck “Auto Reboot” and click on Install.

The tool will flash Magisk V21 on your Samsung Galaxy A70.

-To fix your internal storage showing 32GB you need to use pit file or select all slots in Odin so internal storage won't be resized:

To boot in recovery or boot the system with Magisk installed:

1. Powering up normally → System without Magisk
2. Power + Volume Up → Bootloader warning → Release all buttons → System with Magisk
3. Power + Volume Up → Bootloader warning → Keep holding volume up → Actual recovery


(TWRP is now compatible with android 10.)

To fix your internal storage showing 32GB left instead of 108 (128GB) you need to:
-Resize data partition in twrp.
-or Format data in twrp.
-or select all files in odin so it won't resize your partition
-or use pit file so your device will know each partition size and won't resize internal storage

Can I ask some more info. You had flashed VDF over your old OVF right ? And after that what is your current CSC code ? Does it affect your SIM signal and KNOX ?
Yes i flashed VDF over my old OVF (SIM). My CSC code is the same like it was before and there is no affect on my SIM and Knox.
You'll have to download the complete firmware you want (I used Frija for this).
After downloading and unzipping the file you can flash the firmware using Odin (version 3.13.1) by loading the different files in the right slots.
(CAUTION: If you don't want to wipe your phone use the HOME_CSC-file, not the normal CSC-file!)

Netherlands Vodafone h1 is the newest firmware right? And the next new one will be called I* right?

I am just trying to understand the firmware numbers.

I heard that using Odin to flash something to your phone can make KNOX trigger. So if I want to update rom using Odin, does it trigger KNOX status ?

I'm having a look at the A70 I've got and it's showing up as an A705X variant, It's an Australian version which is not on your list.

Yep , theses are variants modified by ISP provider , here in Belgium we have a SM-A705FZKULUX (SM-A705FN/DS) and also A705XX , sadly the firmwares are not released by ISPs...
