I've just installed it on my V812 V4 no problem.

 

Very smooth, no real noticeable difference with previous 3.3.1 version except for the lower antutu  score (around 12400) which in fact is not lower, it's accurate, previous version score was due to a tweak with the GPU that made it score much higher on antutu, but general performance were the same.

 

No noticeable problem with wifi, all my favorite apps were downloaded fast.

 

Camera is ok, no force close on gallery, or I haven't been able to reproduce it.

 

So far so good.

Thanks for the great update, I'm got very fond of the Google now launcher on my Samsung Galaxy S2 so this is the icing on the cake.  Did have some issues so re-flashed my V812 (v4) and that cured the problems now having similar buttery smooth experiences as lolxdptrd.

Haven't been running WiFi during standby but I will give it a go see if it acts up. What I will report is an incredible increase in game and video applications. 

I stream with Xbmc Frodo on my last ROM 4.22 Kasty Xbmc didn't run so good lagging badly during menu transitions now it's a speed demon. In gaming I'll refer to two games I've played 

Shine runners and Dead Trigger.  Shine runners runs great but hard to see any improvement it's a different story with DT it's incredibly fast at low settings so fast in fact that I thought I was playing a different game. The real improvement was evident when pushed the quality settings to max the game was still very playable which wasn't the case before with 4.22. 

The last thing of note is Chrome browser I had gave up on it because it was terribly slow though that may have been dev issues. For now with this KK ROM it's going great. Happy days on my Onda v812 v4

Muchas gracias por tu trabajo. 

After upgrade the firmware I have an issue, after a quick boot the menu is clean and the applications list is clean too, there aren't any access to the applications. 

If I change to onda boot loader or I make a normal boot the applications icons reappear and all works OK. 

Another question. There aren't widgets in this firmware? I can't use, for example, the calendar widget because don't appear in the widget list. 

Thanks for your attention and sorry for my English.

This only happened when I had made a system change the device needs a full re-boot for changes to take :-)

 

A update on the wi-fi sleep issue which I appear to not to be effected by. My device has went to sleep four times in the past 40 hours and I've no problem with getting wi-fi access when coming out of sleep.

Teoc20:
Push the power button twelve or more seconds to ensure the tablet is off
push and hold the home button and push the power button. Hold the two buttons about twenty or thirty seconds and the tablet must start in recovery mode.
Select reboot and... We see

Definitively tested. I have two onda v812 and after install this firmware I have the same problem: after a quick boot, when I used the google launcher, the screen is clean, all the icons disappear, and in the application list the icons disappear too and can't launch any application. I need make a normal boot and the icons reappear and all work OK. 

I haven't any problem with the Wi-Fi in the two tablets

My best regards

Installed this firmware last Friday and I'd like to say that I am falling in love with my v812 for the second time.  It is in the best state since I bought it.  Speed is very good and wifi is stable.  No improvement is the battery utilization but I'm OK with that.  No issues encountered so far.

Thank you very much for preparing and sharing the firmware.

i justd installed 4.4 kitkat and it runs great very smooth, thank you for this.  i only have one issue and was wondering if anyone else has experienced any issues with adding or finding widgets.  i know it kitkat you have to go into settings and security and check of enable widgets, but even after that i do not see the widgets list.  on 4.3 i had no problems but with the same widgets i had then i cannot find them on kitkat.  has anyone had this problem?

thanks again for a great rom!
