For some reason I can't see the pictures. Maybe blocked by the hackathon network I'm currently on.

Someone posted a very useful how-to SOMEwhere in this thread that should help. It's a pain to find but a joy to behold.

In a nutshell, you want a tiny drop of epoxy under the bottom of the connector. Make sure the PCB and connector are clean. As for solder, you need to solder the usb contacts to the corresponding pads on the PCB. This will not be easy (I failed on one device). You'll need to mask off the PCB real estate between the pads to prevent creating a short-circuit. This is precision work not for the faint of heart.

i bought N900 from my friend.
after some days accidentally, the Charging port broken.
i will try to fix it. but it break with the board prints.
i checked it to mechanic but he also told me that it is not able to fix.
it is very difficult to charge it.
i want to copy of my all data i.e. photos and vdoz of my daughter.
the memory fill upto 25 GB almost.

it has also an error when i save or shoot photos:
"Memory not accessible. Unable to save content".

my Question:
1- can i use it without battery.
because when i use PC suit to copy all data, the battery will fun down during synchronized period.
2- how i can fix the memory error/or update it.

The way I read it is that you can still copy data with the USB cable, but not charge.

I do not know your exact situation so I cannot tell you exactly what to do.
With some assumptions based on your description, I would:
  1. Charge the battery outside the phone. You can use a universal charger like this. (There are hundreds of similar or better ones, this was just the first hit I found.)
  2. Get an SD card and copy your data onto it. Use the built-in File Manager. I had bad experience copying large amount of data with anything else - the watchdog timer can kick in and reboot the phone. File Manager avoids that problem. Then get the SD card out and copy your data from it using an SD card reader.
  3. OR, if copying through USB works, use USB.
  4. Whether you use an SD card or USB, I would watch the battery status and when it gets too low, stop the copying and go back to step 1.
  5. Once all the data is safely copied, format the internal memory. A long press in File Manager offers the "Format" option.
