I want to install the Resurrection Remix custom ROM on my SM-G920I (Australian Version). Before I start doing anything, I need to make sure that the bootloader is unlocked, so I don't brick my phone.
To find out the state of my bootloader, I tried doing a few things that I read online. First, having a look at download mode, by holding home, power and volume down on startup. It instead goes to "Odin Mode" and lists these items.
ODIN MODE PRODUCT NAME: SM-G920I CURRENT BINARY: Samsung Official SYSTEM STATUS: Official REACTIVATION LOCK: OFF SECURE DOWNLOAD: Enabled KNOX WARRANTY VOID: 0 (0x0000) RP SWREV: B:4 K:2 S:2
Do any of these items tell me about the bootloader?
I then tried using the ADB and fastboot method. Fastboot refused to work for me, saying no devices found. I later found out that Samsung devices do not have a fastboot mode at all.
Lastly, I tried just going to Developer Options and enabling "Allow OEM Unlock", but this feature was nowhere to be found on my device.
How am I able to check if my bootloader is unlocked, so I can root and flash a custom ROM on my device?
