Did they release v2.0 for the v813 as well?Â
Just got an one in the mail today and one of your "ArcTablet Firmwares" would be awesome.
I haven't seen a 2.0 release for the V813, but we should be able to make a custom firmware once Onda published one, please let us know when you see itÂ
Cheers

Hi thanks for the rom used it on both my 812 and the version for the v972, sound appears to have improved the only problem I have on the V812 is now catch up tv has a black screen and only plays audio, same on the V972, also on the V812 kept getting goole play had stopped working until I did a factory reset appears to be ok now no error message but still only audio on catchup tv, may be something to do with flash as I believe catchup tv still uses this. nexflix, bbc iplayer and itv player all work,anyone els had these issues.

On my v812 v1, the new firmware lag and much much slower than the Kasty v1.35. Especially when running multiple applications at the same time (multitasking), my v812 make me feel like holding a single-core device. So, I have to go back to v1.35 and wait for a next better firmware version.

Can you give a a more detailed description so we can know what to look for?
Basically what applications are you launching, what was the previous behavior, and what is the behavior under the 2.0 firmware. That way we can try and replicate the bugs on our tablets. It helps with finding the problems.
For example if you are seeing scrolling problems in the browser, it may be graphics driver related or it may be just a bug in the browser. One would require fixing the kernel and drivers. The other would just be replacing the browser or using a different browser.
