Rooted, modded, ROM'd the N9?

[Buschik]

I have just a few old(er) phones (S8+, Note 9) that I wondered if its worth/able to root/upgrade the OS .. from Android 10 to 11, 12, 13 .. only 4G, but thought of maybe using one as a music server to put in the car? Didnt know if this was better here or in the Android group .. Just wondering if rooting was easy enough to upgrade the OS?

US version were harder to Root because the bootloader but XDA forums can help probably have to look into old articles , I have made sticky here for flashing stock firmware incase u get into trouble lol, either way most likely going need to get familiar with Odin, don't put important data on this device because it's not as secure like current Samsung on stock firmware.

I'm just planning to use it as a BT Music server, platform for our tesla, cheaper than the $100/yr streaming, or slap a sim card in for 4G backup phone.

For that I don't see any issues but would have to scroll around XDA site for root

If you have the US version of the Note 9, the bootloader will need to be unlocked if you want to root your device, despite your intended usage.
I have the international snapdragon version of the device so I didn't have to deal with the issue of having to pay a 3rd party to unlock the bootloader.
This is the main problem with the US version.

Yup that's always been an issue for US Samsung devices.
