Default Wanna be sure about ROM update.

Hi.
I've got Qtek 8500.
Radio is 4.1.13.17_02.32.31
ROM version is: 1.02.261.1

On xda ftp i've found this file: 'RUU_STAR100_3.6.251.0_02.67.30_QtekEUR_Ship.exe'. As far as i understand this is rom version 3.6.251.0 (vs my 1.02.261.1) and it's 'younger' than mine. Am i right?
Please, tell me, is this correct file to upgrade my ROM? And if it is not, that wich one is? I don't want to flash with rom from another vendor, just upgrade Qtek.
Thank's in advance.
I only say, suppose the supposition
