you're right, i used testpoint method to have a connection, i update and re freezed the keys in the bootcore, it worked just 10-15 minutes, then it began to switch off suddenly again... the strange is that i could make a fubu without any error, i think a hw problem should have the same behaviour in normal mode and service mode...
anyway i saved all my data, and now i'm looking for a new phone. bye thx
