How do you switch off the HTC one?
Press the button at the top for a moment and the device will be switched off.
after entering the second command it says
“FAILED (remote: 99 unknown fail)”
What did I do wrong?
follow this steps that i take from xda-developers wich helped me with the same problem
How to flash?
(bootloader needs to be relocked)
Re-lock your bootloader (this will most probably wipe content of your device)
Copy downloaded .zip to fastboot.exe location (e.g. c:/SDK/platform-tools/fastboot.exe)
Re-name .zip file to firmware.zip
Open command prompt
Boot your device in fastboot mode (vol down + power ===> fastboot)
Connect device to the PC
In command prompt cd to fastboot.exe location
Make sure you have correct modeid and cidnum (type: fastboot getvar all)
Type: fastboot oem lock (if your device is not relocked yet)
Type: fastboot oem rebootRUU and wait for device to reboot
Type: fastboot flash zip firmware.zip and wait for process to complete
Sometimes flashing for the first time doesn’t work, so flash firmware.zip again just to make sure.
Type: fastboot flash zip firmware.zip and wait for process to complete
Type: fastboot reboot
Unlock your bootloader and flash custom recovery if you are going to use custom ROM.
