The Evervolv Android 4.4.2 ROM for the CDMA HTC EVO 3D hit the ground today in an early testing release version.
As with any early release ROM, there are problems, and with this one those are the camera, a routing issue with the speaker (audio goes to the wrong place occasionally), and potentially mobile data. Unfortunately, we don’t know whether this works or not as the developer doesn’t have an activated device and there has been no feedback as of yet.
Android 4.4.2 features, which Evervolv for the EVO 3D may not fully support, include the ART runtime (a Dalvik replacement), the support of Bluetooth Message Access Profile, all sorts of enhancements that messed up third-party text messaging clients but were probably needed, optimizations for low RAM devices including zRAM support, and support for version numbers higher than 4.4.1.
It’s been a while since I flashed anything on my EVO 3D, but when I get home I’m going to experiment with this.
My guess is as with the EVO 4G LTE and original EVO 4G that a newer version of recovery supporting SELinux will be required; however, I’ve not kept up to date enough in the EVO 3D world to know. TWRP 22.214.171.124 appears to be the latest officially maintained on Team Win’s website for the EVO 3D, and that’s also where SELinux support started, so probably would do you well to grab a recovery update.
Beyond that, grab it and flash the thing and report back to the developer so he can get the thing up and running properly if it’s got more than just a speaker and camera issue.
