HTC One M8 Android 8.1 Oreo Review![Lineage OS 15.1]

If you are still stuck on older Android OS such as Android 6.0 Marshmallow or even Android 7.1.2 Nougat, you may want to upgrade your OS to the latest Android 8.1 Oreo by using the Lineage OS 15.1 custom ROM for the HTC One M8.  This is a full-feature packed custom ROM that will get your aging HTC One M8 to the greatest and latest Android OS.  You will get ALL of new Android 8.1 standard features plus couple customization that Lineage OS brings.

This Android 8.1 Oreo custom ROM has everything working out of the box, for video recording you will have to use the Footej camera from the Play Store but otherwise works 100% flawless including WiFi, bluetooth, calls, 4G LTE, etc…etc…  Installation is also easy if you have rooted your HTC One M8 with TWRP recovery installed, no need to install newer HBOOT/TWRP or anything like that.  I’ve also modified the original files to work on older TWRP versions, so use the modified version below along with the Gapps.  Also, for Gapps, DO NOT USE OPENGAPPS as they don’t work with this ROM!

Overall, this is a great way to increase performance on your HTC One M8 and get all the best features from latest Android 8.1 so if you have an HTC One M8, give it a try and do let me know what you think!

NOTE: You WILL need a rooted HTC One M8 w/ TWRP recovery installed.  If you have older Android version, follow this root guide.  Otherwise check out XDA forums for latest root method.


Download Lineage OS 15.1 ROM for HTC One M8 (modified to work with older TWRP)

Download Android 8.1 Gapps (Use these Gapps!!!)

Download Magisk (If you want root + hide root and use apps like Android Pay)

Installation instructions:

Reboot into TWRP recovery, do a factory reset, install ROM, install Gapps, (optional) install Magisk, then reboot.  That’s it!

    Hi i just installed this rom on my m8 from sprint but i’m having a problem, if i just install the rom alone it boots fine, but when i install the gapps and the magisk i get stuck on the lineage screen in an endless loop, t just shows the lineage logo “loading”. i have twrp installed. Any ideas? Thanks man and great work!

    Good day! Installed the application of Google Pay. But unfortunately it does not work. The NFS module is all right.
