While not yet listed on the supported devices page, the HTC EVO 4G LTE is being served nightly builds of CyanogenMod 10 by the official CM repository. CyanogenMod is a custom replacement ROM for many Android devices that offers speed, stability, and a continuing upgrade and development path after carriers have abandoned a device.
The current CyanogenMod nightlies are based off of Deck’s CMX that we did a hands-on with a few days ago, although they might be a bit behind what is in the development threads.
If you’re S-ON and interested in trying this out, you might have to flash using the latest TWRP with Dumlock enabled. You could use Flash Image GUI, but if something goes wrong, you’ll be stuck with a phone that has an incorrect kernel and no easy way to restore the stock kernel. Dumlock can be enabled under Advanced Options in TWRP and allows for installs to S-ON/HTCDev unlocked devices.
The remaining bugs appear to be as follows: some issues when switching between 4G and 3G/WiFi; an issue where the proximity sensor is wonky in artificial lighting; and a phone process that crashes once or twice after bootup. However, it’s reported that Netflix is now working, Google Wallet is a go, and video recording works on the regular camera.
If you’re flashing it, let us know how it’s working for you.
