Hi ironass, thank for answer.
I try to root it but I can't, nothing work.
Do you know a root method?
I not living in usa, for that reason I can't register on a AT&T network
It's the only way to use OTA?
Is on any place a OEM Firmware? (no AT%T firmware) .
Thank you
Is it possible to upgrade the sm900f to 5.1.1 and if so how?
Unrooted users must be registered on the AT&T network to receive their OTA updates.
Thanks so I'm in the UK on EE, so as long as I root the phone then I can manually install the update?
Can I flash through recovery or odin
As per the first sentence of the link for the 5.1.1 ROM in post #2...
"**You can begin the following process from any Build/ROM but you must already have Root Access**"
As per the installation instructions contained in the ROM link... Flashfire and Odin are required.
