I was trying to change the folder permissions to my Device>System>ETC>Permissions folder to replace the platform file. It would not allow me to replace the file with another one due to the permissions being read only. I had even tried removing the file and placing it in another folder (incase I needed thge 0riginal file again) and was going to then try inserting the new file...it of course wouldn't let me then I remembered when you change the permission settings you have to reboot for them to take affect. I rebooted without putting the 0riginal platform file back in the System>ETC>Permissions folder and now I'm stuck in what I am calling boot loop. It will boot up to the AT&T logo on the white screen and that is it. I'm hoping I can fix this with Odin or something b/c as of now I've gone from trying to install a customer recovery to flash a custom ROM to having a brick (or soft brick). Thanks in advance!
