So I've been having a bit of trouble with the US 4.4.2 rom freezing or stuttering & am losing signal too. I was just going to try a factory reset, but then i thought I might try the DE or FR version instead as this will essentially be what is pushed to the rest of europe.
Trouble is when I try to flash the 4.3 DE rom it fails with a downgrade error. I'm using the flashall.bat that is included in the download. I presume this is because im already on the newest version.
Just wondering what is the best proceure for doing this? Do I need to go to UK stock 4.3 first, then DE 4.3?
