Question [Q] Optus ROM on Tesltra SIII 4G?


It looks like Telstra are being arseholes and are dragging their heels with updating the ROM in the I9305T to 4.3. Can anyone see any issues in downloading and installing the Optus ROM for the my phone? Is the ROM compatible or will it brick the thing?

There is no problem BUT REMEMBER, dont flash the new modem. The S3 9305 and S3 9305T are almost the same except for the modem part. I have a S3 9305T just like you and decide not wait for the upgrade so, I used Mobile Odin to flash a 9305 firmware deleting the modem part to stay with the old one from 9305T (android 4.1.2). You will need to flash tha AGNi or the Boeffla Kernel too or you will not have the wifi working with the stock kernel.

Good luck!!!
