Ok, you removed it maybe with the wrong archiver hence the file gets corrupted. Please use 7zip, mixplorer or totalcommander and try again(first you need a new rom file which isn't corrupted).
I removed it with WinRar from PC. Now I'll try with 7...
Works with Vodafone Turkey
Edit: Used Telifonica-UK btw
This is my dream app, thank you so much for making it come true.
