Ok man,
I did try this but no luck. I also tried many other images than SifTeam and still have the same problem.
On a brighter note, NOT all folders are read only. I also found from other forums that the majority of Enigma based images have the same restriction when you try to modify the contents of specific folders such as the /share folder. In other words, the creators of Enigma based images deliberately compile those images and add the read only restriction to some sensitive folders such as the /share folder.
I will be grateful if you can post a link to an Enigma based image for relook 200s and doesn't have this silly limitation.
As a Linux fan, I will also try to look around for a way to remove this terrible attribute from the required folders. Or if you know how, then you will save my life

.
Cheers,
