I provide no warranty or guarantee with these files… if you brick your device its your own fault.
I need to save these somewhere. So I dumped them on google drive.
Using these files here will convert your dual booting Onda v820w v3 tablet back into a single booting Android table with a 32gig drive.
The files will allow you to root the device using TWRP. Leave a comment below if you need assistance.
