Question about Sony Ericsson Z550i Cellular Phone
I currently have a Sony Ericsson z550i Mobile Phone and I want to update it's firmware. I already have the MBN File (Sony Ericsson Mainware File) but i don't know what to do next. I have already tried copying it to my phone but the file is useless. Any Ideas?
firstly: use the seus i.e the sony ericsson update service. its an online free update service by sony. its installation package comes with the phone, ona cd. connect your phone to the pc with the cable and run the soft after installing it. follow the instructions.
secondly: if u want to do it urself, then u ned some third party software like XS++, and some more files known as cust packs, main and fs. the mbn file is not the "firmware" but the "main " of the phone. so its not recommended to "flash" the software at home if u dont have the advanced knowledge about "flashing"... u may brick your phone. (make it permanentally damaged).
u may learn the flashing process from the site: mobilejunkies.net
hope this will help!
