got a question on my i9505. i have installed this rom I9505XXUFNA1_I9505OXAFNA1_I9505XXUFNA1_OXA.zip for a while and due to my local telco running only 4.3, they mention that my phone is grey unit and they do not want to warranty it.
i'm wondering if i can re-flash back to its original 4.3 (telco) rom using odin without issue so that i can bring have it repair under warranty.
any gotchas should i look out for?
thank in advance.
