I live in Latin America and I found out here governements dont require Samsung to OEM lock bootloader for Samsung phones, so thecnically im able to boot a custom rom unto my phone. But Im curious if this still enables us Samsung users from Latin America to boot any privacy respecting android rom, since most of them doesnt support Samsung devices at least that’s what they say on their web pages. So, do you guys think there’s a solution for us?
If you are able to OEM unlock, you probably can flash a ROM of your choosing. Now find a rom that is compatible with your device.
As other have said, calyx, or lineage are good options. but if there are unofficial they are likely to have security vulnerabilities. If thats not a deal breaker for you than try it out.
Ps make sure you have a usb 2.0 or newer. a cheap usb 1.0 will not work.
Get adb and fastboot.
Let me know how it goes!
