Sorry, my boot loader write:
I can not update, stops at 0%. I did as the instructions say....
1- put your TP in bootloader mode (power button, camera and reset) then plug it on you pc.
2- Try again the RoomUpgradeUltility software, if no success go to next step!
3- With your device plugged on your pc, go to hardware management and remove the Microsoft USB Sync device. Make the hardware management to find new devices, they W'll find the Microsoft USB Sync device again. Try the updater again. If no success yet, try to change the usb port or: keep your device in bootloader mode when run the RoomUpgradeUltility plug your device.
