I have made A new install of emuelec 4.2 on a 32 gb card But now I have the same problem as my old 3.x install Screen overscan. When I try the same method i used on the 3.x version by modifying setres.sh, I get the error the file is unwritable. Copy the file to another location as suggested by ShantyGilbert make the file editable. But when i try to copy it back to the original location i cannot overwrite the original setres.sh I have set the file attibutes to 777 I am hoping somebody can give me a tip how the overswite the original file with the new file ---

Do not copy it to the original location, edit and leave it in `/emuelec/bin` ---

When i reset the device the overscan is back ---

Hmmm yeah you might need v4.3 for this: But try this, put your commands on the `custom_start.sh` file and try if it works like that ---

Hello emuelec, This works. But can you tell me why the file system is read only? So I cannot edit any of the files there It even is inpossible to set attributes for the files there. But anyway thanks for the help Greetings Herman ---

> [@ducdreamer](#): > > But can you tell me why the file system is read only? Because people kept screwing things up and I am tired of answering the same question 1000 times. People just change stuff that they don’t even know what it does because they read half of a post somewhere, then come to us for support and it gets tiresome and time consuming. ---
