here you can find another rom not belong to Yoigo... but it is fomr Australia Operator...
Ouch, I meant that the rom you linked is stock (no brand) and I was going to flash it, but as I can see the yoigo one is newer.
Maybe the Australian one is rootable with classic root tools, but I wouldn't flash with the AU rom if I don't have the Yoigo one to come back...
Is there a way to save the Yoigo rom from the phone?
