Hi. Sorry it took a long while. I tried to implement MangoOS mode since last few days and couldn’t get it to work. I managed to get to Mango option available but couldn’t change bootmode even with adb shell as root. I’ll settle without it for now.

After releasing DX150 Oreo ROM update in previous post, I started working on DX200 ROM update right after. It seems boot image in DX200 had some stability issues with modification so it took a while to fix it. Please always flash official version before Purist one.

Sorry it took a long while. I already sold my DX150 (that I bought for testing ROM alone) to my client’s friend. It took me a while to find unit to test and ended up doing it with testers instead. After confirming the Purist ROM works fine, I rushed and finished it today.
