which c905 firmware to use

I debranding her c905 last night using 042 firmware, all went well using a2uploader, but i was wondering.....

I assumed this was the latest fw due to the higher number, but is it?

Should i have used something else, and if so, is it now possible to uodate via seus?

TIA

you can use seus program to check your phone,if you r not sure.
