done na po sir na iedit, may additional methods pa po bang gagawin? i.e. reflash po? biktima kasi ako nung wrong code sa zt. baka reflash nalang pag-asa. kahit sana di 2.1 or 2.0 basta mapagana lang ulitSome vim keys po: press 'i' to enter insert mode, do your edits # to comment out a line.
Then press ESC to enter normal mode again, then ":wq" to save and exit. If you made some mistakes you press ":q!" to quickly exit without saving, ":q" to also exit a file.
Also in normal mode you can press "dd" if you want to delete a line rather than commenting it out; keys h,j,k,l also acts as navigation keys in normal mode.
