I've a W550i that had the WSOD, I downloaded what I THOUGHT were the right firmwares to flash it and restore it, but it didn't work. Now, it connects to the Phone XS, but can't flash it. I know that I have to make a FULL FLASH, but I don't know what FILES I need to do it. Also, I wan't to activate the flash menus and stuff, but make it work most of all.

Can you tell me what firmwares to download? I couldn't find the specific thread about it, I mean, what files I need for full flash.

Thanks!
