Thanks David,
I looked up the thread where the DNX mode is explained (Guide Install Remix Stock). The guide is put up by User: Jt (thanks to him) for Hi8 but I guess it will also apply to Hi10 Plus as the partition resizing part I believe is device independent as the booting takes place from an USB but ofcourse the partition structure maybe slightly different to what is explained there, the idea remains the same. Only the stock ROM & drivers etc are device specific.
I have to study this procedure and will report back if I succeed in this.
Thanks for your quick response.
Sunny
