This "may" work, however I've never tried it
Thanks for the tip. BTW I notice you are a fellow aussie, what modem do you use in your phone?
My I9305 is apparently an international version and has HK firmware. Reception is terrible here in Brisbane yet my old S2 was great (but it had aussie firmware). That's why I thought maybe a different modem might help.
Sounds like you were with Telstra. I noticed on Sammobile that the 4.3 firmware put out by Optus has the XXUENA2 modem. I'm with Optus using 4.3 so thought that modem would be the best way to start. Will flashing the XXUENA2 modem on HK firmware work or do I need to flash the entire stock australian firmware?
I have extracted the latest baseband from Three (H3G) ROM (June 2014 from SamMobile) and flashed with Odin and t it is finally working perfectly on Three UK.
The baseband version is: I9305NEUEML2.
I've tried to upload but it's too big (45MB).
Let me know if you need the tar uploaded somewhere.
