I did use this command 'rm rt*' (whats that exactly? dont wanna remeber again!) while installing NITDroid.
And I ended up with NO BOOT at all! so I flashed N900 but only could flash by using 'combine.bin'
I wanted to delete '/and' folder but I used this command for '/home/user'.
I know I have done a BIG mistake but do me a favor and for God's sake give me a solution for this.

ow I have all my Data with me.Contacts and everything.but can not use N900 as I used to

Problems I face :
1) My legend phone can not read SIM card.
2)It does not connect through USB so no chance to update its software through NOKIA Software Updater.

Its just a media player now,it kills me!!
I can connect to my WiFi,is there any chance I can fix things up using X-terminal or Apps Manager?

So please,please and please REPLY asap if you have any suggestion in your mind.

I wanna see my N900 working as it used to!

Please guys help me out,please asap!!
