W810 Version Numbers

So, I'm not a pure noob... as I've debranded about 4 phones so far... but while cleaning up all the firmwares I've massed I noticed that there are no FS files to go with the W810_R4EA031_MAIN series.... and no MAIN files to go with the W810_R4ED001_FS series..... which gets me thinking...

Can different firmware versions be used with different file system versions or do they always have to match?

Thanks all
Kam


-btw... can a mod take a look at getting me into the downloads section.... I still can't download, but have been active... for quite a while....

R4ED001 is the suitable FS for the R4EA031 MAIN, don't worry about that ;)

Those two go toghether, it is perfectly fine, Don't mix other versions, those were designed like that, don't know why. :)

are you examin it ?
why it dont work?

Thanks to all who answered my question, but... concerning access to the downloads section... I've submitted several times to that "request for access" forum.... with no results... I dont want to flood it with requests and tick anybody off... nor am I in an extreme hurry to get the firmwares... but I feel alot safer getting them here then those Russian sites.... ><
