Currently HTC has not yet released to us the Marshmallow update for the M8.
Updates should have gotten to us by the end of 2015 however still no word from HTC.

It's now March 22. HTC has shown your M8 to be in the "certification" stage of the Marshmallow/Sense 7 update for over a month. Several ATT M8 customers who have called customer care over the past month and a half also have, initially, been given the story by ATT customer care representatives that the software was having to be re-tested due to "bugs" in the original software. That, too, was over a month ago with no status report on the update having been given since. All HTC M8 customers want is an approximation of how much longer we can expect to wait for the update. Especially since ATT is, officially, the LAST to provide the Marshmallow/Sense 7 update to its HTC M8 AND M9 customers.

Finally just now received a reply from Mo Versi regarding status of the update. He says; "We're pushing the carrier as much as we can, but, right now, it's looking like the end of April." So. Seems like ATT is being the holdup, for whatever reason *coughs* bloatware *coughs.* 😒 On the bright side, at least we have some sort of time frame now.

Just a heads up everyone. HTC's Mo Versi just posted a status update for the Marshmallow update for the M8/M9 on ATT. He says they've run into some "slight delay(s)" and are now "looking at approval within the next couple weeks." No idea, at least at this point, what's been causing the delay(s).

I see that AT&T Marshmallow update is available now for my HTC one M8 phone. But the installation is not going through after downloading the update. I am getting the following error when it tries to install the update:
Opening update package...
E: failed to map file

Hmmm ... That's odd... Mine went through without an issue. Is the update still available for installation? Have you tried turning the phone off, back on, and then trying to install it again? If the update is still available for installation, but you haven't tried power cycling and attempting the install again, try that. If the update is still available for installation, you have tried the power cycle and the install still fails, the last resort would be a factory reset and try to download and install the update again. Failing that, I would take it into an ATT device service/support center, let them know what you've tried, and have them take a look at it.

I am having the very same problem with our two M8's as well. I called technical service and the guy on the chat line told me to power down and then remove the battery. I tried to tell him I was pretty sure you couldn't open the case but he insisted you could, so zero confidence there. I called support the next day and she said she would push the update out to both phones. So, something kind off odd there. I got an update notification and whatever it was loaded very quickly, and then got another notification that an update was available. I was hopeful thinking the first thing was some sort of patch, so I tried to download again, waited 1 1/2 hours again only to have the same fail. On both phones. And this was after I powered both phones down and cleared the partition cache. It is clear to me something is wrong with the update. I am not about to manually download and wipe the phone, so I suppose I'll have to do without until they fix this. On a related note, even though I have been with At&t from the beginning, through the Cingular years and still with them when they went back to At&t, I am seriously considering switching to T-Mobile chiefly because of the incomprehensible decision not to carry the 10. I know I can buy the unlocked version directly, but I really don't feel like shelling out 1400.00 for two phones that as I understand it don't really completely work with At&t. Yes, I realize that I will still pay that through the carrier, but somehow it just seems more palatable when it's part of the plan and not an additional bill or cash drain. All in all very disappointed with the update and even more so that they will not carry the phone I want.

Hmmmm... Starting sto seem like I'm the odd gal out 'cause my update worked fine the first time around. I feel you on the decision not to carry the 10. Good news is, HTC's got a financing program if you buy direct from them, but, bad news is, you're right, it won't completely work on ATT 😕 ... Looking like either Verizon or a Nexus phone for me. Wanting to see if the rumors of HTC building a Nexus phone... Or two... Is true or not though before I set any decision in stone.

Thank you so much for the great questions, and feedback regarding this update. It seems that many of you have been able to successfully download the newest Marshmallow OS for the M8 and M9, but if you are still having issues, please see the info below.
We have heard the feedback about the large requirement of free space needed for the install and have sent this to HTC. At this time, HTC has advised that the free space required to download M8 and M9 are 1212.5MB (M8) and 1552.88MB (M9).
Once the package is downloaded, the installation requires 150MB (which was already reserved during FOTA download).
Although not supported by AT&T, HTC has advised that customers can sideload the update to bypass the large storage requirement.
Here is the link for your information:
Please contact HTC if you have any questions regarding the below information. Sideloading will wipe your device and restore to factory settings.
If you have other Marshmallow related questions, please join the discussion. We will announce all future Marshmallow info here.
