I put it on my T-Mobile 8800 a couple of weeks ago, and it works great. It looks like it even solved a few nuance issues I had. As mentioned, you have to delete the vendor.xml file or the Desktop Manager will not recognize that an update to the OS is available for install.

I have downloaded the os file... it says TIM Italy...?
Every time I click to install it gives me an error... trouble with initialization file?
Any suggestions?

error reading setup initialization file

Did you delete the vendor.xml files as instructed in the first post?

The TIM OS will work on any 8800 model, as long as the instructions above are strictly observed and performed.

yes I did but i will try again... thanks

the only xml file there is the device xml file

I would recommend downloading the OS fresh again, install it, and follow the instructions above.

I am downloading it for the third time... deleting the old one... is there another site to get it from?

i clicked run instead of save to disk... looks like it might work this time!

still didnt work... am redownloading it ... the other 4 times the file sizes did not match what the faq said... should be 88.8... but they were 50 to 60 meg... dont know what that is all about...

Are you running Windows Vista or XP?
