I have an HTC one with a booting problem. When I power up I get to the bootloader screen and none of the options work, I.e. reboot, reboot to bootloader bring me back to the bootloader screen teen. Reboot to download mode just gives me essentially the same options but with the addition of System Info and Show Barcode. I cannot get past the bootloader screen. Any help would appreciated. I have data on the phone that I need so I cannot do a factory reset.
