Post #1 gives the changelog from the manufacturer, translated from Chinese.
I haven't tested the firmware enough to report changes, but it seems stable so far.

Thanks a lot!..there seems an issue when I try to flash unrooted fw v1.32(i have only the unrooted fw v1.2 the pop up window won't show up when  I try to fllash it. What I did was to reset it to factory settings and directly flash the rooted fw v1.33 and it works.

Hi All,
Did anyone noticed/encounter after installing rooted fw v1.33, It's very difficult to turn it on the V812 tablet(after shutting it down) I have to press several times until the CPU logo appears. I dont think my tablet's power button has an issue because when the unit is turned on the power button works perfectly. Is there anyone encountering like this?

I installed v1.33 and v1.32 I have no more than the problem of wifi and space devoted to the app has returned to 2 GB,
everything works fine and no problem.
If someone has installed the v1.33 could postarmi the app "update.apk"?
restoring an old backup I have overwritten the application with that of v1.32.
thank you very much
I've rebuilt the custom firmware (see post #1) now including latest SuperSU 1.20 and added ArcTools for easy CWM Recovery installation, please check details here.

After installing this ROM i get the message to update the superuser in the play store. I update it and i notice that the superuser icon changes and then when opening it, says i need to update the binaries. Says that it fails to update. Tried to use other su update apps and there all a no go. Also cant write to the internal sd or mount the internal sd with es file explorer.Â
