Good morning FAME, welcome back to the Forum. Your REMIX OS11 roms post caught my attention. I have a functional Teclast X10HD 3G tablet with a corrupt Android O/S but it was running Android kit kat 4 point something or other. Did your ROM versions apply to this series of Tablet successfully ? I have not reformatted or re partitioned , reflashed an Android device before. I have 3 different android KitKat 4 devices and frankly I found that version quite unappealing but warnings of upgrading failures put me off trying. It was a dual boot Windows/Android device but whatever crashed it, I believe damaged the O/S partition so I will probably have to begin from scratch.
Regards from Rod
