Bit Banging Broken Cell
Brendan Clements wrote 03/13/2015 at 05:55 • 1 pointI have an HTC One M7 that died a while ago. During an update something happened and it will no longer boot. I have tried everything and after a lot of research have discovered that this is a frequent problem that can only be fixed if the phone had security disabled for root, which mine was not. I have seen people say that it can be fixed if you use JTAG to re-program the phone directly. I don't have much experience with this sort of thing and am wondering if it is possible for me to do. Can someone point me in the right direction? I love that phone and it's in perfect condition so I hate to waste it. Thank you for your time.

Thank you again for the replies. I will check to see what driver I need on my computer and give this another shot. I'll let you all know how it goes.

I tried going down this road before. Factory reset won't work and the computer won't recognize the phone :( The forums I read said that if I load the bootloader and it says S-ON it's impossible without bit banging it.
Again I appreciate the time and effort you all are taking to help me out. I should traverse down the rabbit hole again to try and find the exact forum strings to show you the conversation's I am referring to.

Yep, everything that Hisham Daou said, you just boot into bootloader and reset the factory image, that should fix things.
That said, DO NOTE THAT THIS WILL REMOVE ALL YOUR STUFF, so its advice-able to either share all your contacts with Google (so you can pull them from Google again after the reset) or use any of the dozens of backup applications 'out there'. (Titanium backup is one of the best rated ones, to my knowledge)
Then, for doing the update (the one that broke your phone this time around) make sure you use a decent wifi to download the file, else you may download a corrupt update, wich may be what caused the thing to break this time.
Also, if you do need to go beyond what Hisham just explained, by far your best bet is reading some guides on XDA-Developers, find them here: http://forum.xda-developers.com/htc-one and dont hesitate to register there and ask people, in general XDA'ers are very nice and informative.
Btw, sadly, theres a small chance you 'wasted your chances' on gaining root access, since some of the recent firmware's actually lock that ability (for whatever silly reason HTC likes to deny custom roms every once in a while, and apparently there are some official firmwares for the M7 floating around that do this 'locking', so take that into account, if you do wanna install custom firmware at one point, you may wanna omit the official updates)
But realistically, the factory reset option should suffice, again, just make sure you have a backup of at the least your contacts (but things like txt messages and email could be nice to backup too)

Thank you very much for the reply. I have never rooted the phone or anything, the issue was very specifically caused by one of the updates that was released to the android OS. I can get into the bootloader but beyond that nothing works,
