Flashtool Xperia Driver Pack V19 New
The "new" pack uses a revised Android Debug Bridge (ADB) driver that reduces the "device offline" disconnections during long operations (e.g., dumping TA partitions or backing up DRM keys).
Many users on XDA Forums reported that older driver packs caused a looping "Unknown USB Device" error. Version 19 includes a revised android_winusb.inf file that fixes this conflict, particularly when switching between MTP and Flashmode. flashtool xperia driver pack v19 new
