i have run into some more problems. i totally reflashed and started again and this time when i follow all instructions i get up to (mkdir ~/bin) it says cannot create directory already exists. this is when doing it for the first time. i carried on and when i get up to (cd ~/bin) it says cant do cd to home/user/bin when i do (chmod +x nupgrade.sh tar) it says no such file directory. after typing becomeroot and i type (./nupgrade.sh wipe) it says ./nupgrade.sh: not found. please can someone help i do not have a clue what i should do. i am still currently in x terminal and it says/bin #. where should i go from here? (i am doing this on the internal memory card on my N810)
