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.
