Trying to flash upgrade my W550i is impossible, help? :(

[Mr Brownstone]

Right, to be quick my tit of a girlfriend dropped her W550i in the sink with water when she was pissed and it was completely ****ed.

I managed to run SUES and get it running! Then she doesnt want it, so I decided to keep it and flash it with W600 firmware,

It didnt update though to CID52 :S, it persists to stay at CID49, and when I try and update it through SUES it says it's already updated.

Although when I switch the phone on after updating it it says please wait, and the bar goes up about 10% then just displays the menu.

So I think that the files are corrupt on the phone so I have spent the last 3 days trying to flash it with XS++ and SETOOL2 Lite.

This is the specs of where I am so far:

Model:W550i
MAPP CXC article: R4CB020 prgCXC1250031_GENERIC_EL
MAPP CXC version: R4CB020
Language Package:EUROPE_2
Default version: R4CB020
Platform: DB2010
16:25:07| OTP CID: 49
16:25:07| EROM CID: 49
16:25:07| EROM Color: Red

I can't get anywhere with this. I tried flashing it with...
W550_R4CB020_MAIN_EU_EMEA.bin

and it goes so far but then complains:
SFA block not accepted.

Can anyone say what I can do now? And possibly supply me with the files needed to do this? It seems anything I try just ****s up.

Please help me

Thanks
