Hello guys, Ive searched this forum but i didnt come across my problem. I am unable to connect my n900 as mass storage or pc suite.

let me explain a bit of history:

I accidentially deleted some system files after which the fone couldnt boot up.

I reflashed it using the latest firmware (not the eMMC as i have alot of data on the Mass Storage) (i flashed it on a windows 7)

After the reflash everything was fine and i could connect via USB to any pc and my n900 got easily detected.

Then all of a sudden I am unable to connect at all. All the windows 7 ive tried when i connected the pop up menu which asks u to connect as mass storage or pc suite doesnt shows up and on windows it shows "the device you have attached has malfunctioned"

After sever attempts of changin usb wire and trying to connect it on a Mac did not work out as the option never popped up on the fone and it did not even charge when the fone was on but it charged normally when i attached it with usb when turned off.

I then using the application manager updated to Power kernel then for once it started showing the the pop up menu on the phone but when i selected mass storage then nothing happened at all. i tried dis connecting and connectiong again but still the same but it some how started charging but still no connection to the USB.

Please help me as to what i am doing wrong or what is wrong with my phone.

I would really appreciate that. And I am not an advance user so please a complete guide would be greatly appreciated.

Thank YOU in advance...
