hi all and happy new year. im having trouble getting my sisters phone to boot up it wont boot past htc one screen. I have tried wipping cache and factory reset in stock recovery it goes to android is upgrading but when it gets to finishing boot it hangs there constantly. I an a sony man so have no experiance with htc. I have read a few threads and am still unsure about the prosess of flashing stock. It is stocked and locked and a uk device any help would be apreciated thanks

You have to wait a long time for bootup. Even after white HTC screen which can take a few minutes, it will optimise 165 or so apps on MM 6.0, and 265 or so in Lollipop 5.0, depending what you have. Try going away for a half hour while it boots.

Another thing you might try is when it goes on hanging in the 'finishing boot' for a long time so that you think it has completed optimizing of the apps, (wait 20 minutes some apps take minutes to optimize, and there are as I said over 160 at least) , turn it off again by holding the power button for 15-30 seconds or however long it takes to get it to power off. Then restart again it may come on.

*if the power off alone doesnt shut it off, power off+vol down should.

Tried all that mate. When I hard reboot it (power vol+) it stays stuck at htc one screen left it for 30min or so and still no boot. I tried to logcat while its booting but it won't logcat either. I really need the stock rom but unable to find it I have tried a few zips but got error wrong footer

You need a ruu but unfortunately ruu is not available (afaik).

Worth a try ... flash htc signed firmware fw_6.13.206.5 that you can get from same link above on post #5.
Most important is too see whether the firmware can be successfully installed with no error. If there is error, I'm afraid that will be hardware.
