Cannot rename system files after root

[dawids9]

Hi, I rooted my phone in order to change the shutdown.qmg and bootsamsung.qmg to an end with .bak or .old so to delete the logo from my carrier when starting up/restarting.
Yet, any app would not let me rename the files after a root. With this I mean root browser and other. The phone was set to factory settings before rooting. Thank you in advance!

Root would only give you the authority to change the r/w permissions on a file. I think you still need to change those file attributes in order to rename it. I think any root explorer would enable this.

Hi, thanks a lot. It worked and now when turning off it shows the original samsung logo Only thing which I can't figure out now is why the screen is just black (where the carrier's logo now disappeared) when turning on the device. Might you know a solution to this?

I'm sorry, you'll have to hope one of the more technical folks here knows. I get the basics and the concepts mostly.

Note that it's for a S3 but if you read through the comments others with different models have been successful at this so just be flexible to make it work for your S6.
