no problem at all.

my name sounds like spanish for a good reason. my english looks like spanish too

This forum is a bit too tought (even rude), there are an english-only implicit rule, but whatever, its ok for me.

Please take your time and read the forum. Not everything because this week everyone is running with 1.2 and its crazy, but there are a info by tons.

Also, i have not experience with NSU. I know only OTA and Flash.

for OTA, you need 50+ mb of free rootfs space and several applications are known to be blocking the update.

for FLASH, you only need to mess a bit with the command line and several persons has reported problems with x64 os, and you need to reinstall your apps but its a safe way (with the proper backup, of course)

here is an useful link: http://wiki.maemo.org/Updating_the_f...ndows_7_32-bit

thats for flashing.

keep asking and have fun!
