Flashed official rom for GT-i9505, cannot get past first time install

[Owain Esau]

Hi;

I recently flashed the stock rom back onto my phone (GT-i9505) using odin. Everything went well but when i start it up and the first time installation comes up i get all these errors saying "Unfortunately android.process.***** has stopped) the one that constantly pops up is android.process.acore. I am also unable to boot into recovery so cannot clear the cache.

Please help!

Regards
