Hello guys, sorry for writing here but i could not find the right category for my device. I got pioneer avic-vh09cs and i was trying to change the default language to english.I was trying different methods written in your forum (including Condi's hack and etc.) but i couldnt enter testmode with developer privileges so far (i cannot copy or paste files in the file explorer in the testmode menu).I can only enter testmode using the combination navi+(left+right)x10. I was wondering where i can get the right testmode.key for my device or create one. Thank you in advance if any of you got an idea how to get the work done.
