Want to install custom ROM or a custom kernel on to your Samsung Galaxy A71? You will need to download and install custom recovery like TWRP onto your android phone.
Go to developer settings and enable [OEM Unlock] on your Samsung Galaxy A71
Reboot to download mode on Samsung Galaxy A71
When prompted, press and hold VOL + to enter bootloader unlock mode
Press VOL + to confirm you want to unlock bootloader, this will wipe your data
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.
Go through the initial setup. Skip through all the steps since data will be wiped again later when we flash OrangeFox and magisk
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
Your bootloader now accepts unofficial images in download mode.
Now, we will flash Orange Fox custom recovery onto your Samsung Galaxy A71.
Boot to download mode and load OrangeFox Recovery tar file and VBMeta disabler tar file in AP and BL of Odin, doesn’t matter which goes where
Disable [Auto Reboot] in Odin on your Samsung Galaxy A71
Flash the custom recovery.
Force a reboot by pressing VOL+, VOL >> and POWER buttons at the same time
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 OrangeFox Recovery
After booting to recovery successfully, go to WIPE in OrangeFox
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.
After formatting data, flash the Multidisabler zip with OrangeFox. This is done to avoid future bootloops.
Flash magisk.zip to root.
Reboot to system
Wait patiently for the Samsung Galaxy A71 to boot for the first time
