Hello there,

Recently I tried to install Java on my N900 and accidentally and because of my stupidity I deleted an /usr/bin file while being root. At that time I thought nothing of it and when I couldn't connect to WiFi I tried to restart my phone because in most of the cases that was a deal. Sadly after I turned it off N900 wouldn't turn on - there is just white background with NOKIA logo and it freezes.

I tried to fallow advices from this post http://talk.maemo.org/showthread.php?t=86547 as I really wouldn't like to erase all of the data stored on N900 because I've got a bank account passwords there and nowhere else... But my N900 can't be connected to my laptop when I tired to re-flash it. System doesn't recognize it and can't install drivers.

At this point I need to add that there have been a very long problem with charging my device when turned off. It started normally, but after a yellow light (meaning it was charging) appeared 4 times n900 kind of tried to turn itself on. There appeared this white background with nokia logo, after that a "loading" screen (moving dots) and then it always went off without charging at all. I became frustrated by that and after one time my battery was decharged I thought I lost my phone but I found a solution for that. After a phone wanted to boot up I disconnected a charger and when it was about to go off I plugged it in again and it was charging again.

Now the same thing happens when I try to maintain an usb connection with n900, but here a trick with pluggin on and off won't work. (now, when I deleted /usr/bin I can't even charge it at all, my trick isn't working anymore)

At this point I am desparate because if I lost all of my data from n900 I'm in really, really deep **** and it would take months and a lot of money to repair that damage. Any kind of advice will be more than welcome...

If your data is in MyDocs just reflash (not full flash, just the standard rootfs one). It will fix your /usr/bin and make the phone bootable again. If you kept that data on rootfs... not sure if there is a way to retrieve it unless you installed MyBackupMenu or similar

As above
http://wiki.maemo.org/Reflash
Follow instructions for COMBINED or FIASCO reflashing.

I have not worked out why people still don't store important things on the SD card.
I have everything (Music, Documents, Backups) on a 64GB card it just saves the hassle if a full reflash is required.
There not really expensive and definately worth it.

I kept all of my important information in wallet application :

And as I said in the first post: I can't maintain an usb connection with a PC. It just tries to boot itself up or if I hold an 'u' key while plugging a cable in there is just nothing, just a windows sound for plugged in and immediately after that plugged off sound...

Try flashing from a linux box, works pretty much always. If you're paranoid contact the app developer, he should give you hints which files to backup after reflash to copy over again after app reinstall on fresh device (assuming app during setup/pin definition generates different files). I highly doubt this app stores things on rootfs, you should be golden

64...gb...card...?

If you are using Windows 7 64-bit, try using the wiki, the USB fix works for all my reflashes.

thank you misterc and sixwheeledbeast. you taught me a valuable lesson i will never forget for the rest of my lives.

Just keep in mind highest GB out there is very often totally contrary to what one is looking for. No idea on this cards' random read/writes, but so far lesson has been: Biggest in HD camera recording is also slowest for anything else (10-20 times slower). For backup will be awesome, for storing data that needs quick access often, most likely worst (which is why for ubuntu booting class 2-4 are best)
