Hi, I have tested the image:
MXIII Plus (S812, 2GB RAM, Gigabit LAN, AP6234 WiFi):
Index of /3rdParty/S8X2-LE-9.2.6/MXIII-Plus-S812_2G-AP6234/
On my Android Tv Box device MXIII-G (6 years old), and I am very happy:
MXIII - G 4K x 2K TV Box EU Plug 2GB+8GB TV Box Sale, Price & Reviews | Gearbest
Everything works perfectly, there are no freezes in the device, Wi-Fi works at upload / download speeds of 21/15 mb, with cable 160/60 mb. Bluetooth is also functional and all the functions of Kodi 18.9 at 100%
And I was able to install in nand through Putty.
Thanks for your work from Spain.
