hi please am in Ghana i have galaxy s5 sprint (sm g900p) which is unlocked but am having boot loop issues,ive used odin to flash a few samsung devices perfectly, and i know sprint is a US network which mean any sprint phone needed to be unlocked to be used here in Ghana,what happens if i flashed my unlocked sprint s5 with any other sprint s5 firmeware? will i still need to unlock my phone before using? thanks
