Help needed for Energy Pro HD

[Avi Wadhwa]

Hello all! I just got a new Energy Pro HD (rebranded Boyue T64D, or T62D, I am not sure) about a few months ago, and wanted to experiment/improve it.

First question, is there any superior firmware I could flash on it? Currently my device doesn't support "A2", while those devices which do are based on a different device (T62) so I am stuck with the Energy ROM.

Next, can I make a normal app the "home" app? I found a simple EINK launcher for the Yotaphone, but I cannot make it the home app. I am root if it helps.

Lastly, does USB OTG work on this device?

Thank you all
