Onda Z AIR - Custom Rom for Onda v989 AIR (1.06)

Recommended Posts

Hi,

Thanx very much.

but... It's rather alfa version.

Laggy only a little bit less.

Same games not run - for instance LEGO SAGA.

Troublesome wifi.

3dMark result is the same - about 4 700.

AnTuTu is unstrustworthy.

Will it be possible to exlude the A7 processor.

I want only 4 cores of the A15 processor to work.

No,but you can install a app (like setcpu) to control Cpu and select a governor like performance. 3dMark is more for graphics bench... Gpu is very bad... No miracles... Sorry

It is really not adpart fault it performs as shit in 3D... You can try to lower resolution to lowest acceptable setting, it could help with performance in games, but i'am not sure. It will not get better in the future as GPU is old one and any driver update will help it to perform better.

 

Only thing you should say to adpart is thank you..

 

Question: Is cell standby problem is removed in this update? It was discussed in other thread.

 

I will try out this update ASAP.

Thanks adrpat for your work and bigmoonface for the tests.

I will try it when i will have more time and give some backups.

Regarding hardware, ok it's not like the original V989 .

But i've done some search and this GPU is not so bad too. But like is it now it's impossible to play for example to play at asphalt8 : lattence, crash , etc ...

We can only hope that an angel will give the possibility to give more energy to this tablet

Seems better for me and less laggy, its true though AnTuTu is unreliable!!

I agree the hardware is far from terrible, its the software that's the problem. This tablet is never going to be as good as the A30T version but I think it can get a lot better. Hats off to Ardpat for making a great start. I'm hoping that a lollipop upgrade will appears and solve many of the tablets issues!!

ok people lets take some comparisons

​Onda V989
Power VR G6230 : 64-core GPU
​2014 architecture

Onda V989 Air
Power VR SGX544 : 4/2-core GPU , comparable to Mali-400 :o (this tablet don´t have the SGX554 MP4 that have 32 cores(4x8), like ipad 4 or iphone 5s...or a SGX544 MP3, like galaxy 4, 32 cores too)
2010 architecture

Imagination's PowerVR it´s no longer supporting this GPU (powerVR 5 series), so, i think there will be no update drivers, and no lollipop :( sorry it´s my opinion !
if you go to imagination´s site (http://www.imgtec.com/), they even make references to SGX544

I would never buy this tablet, It´s like buying a laptop with a i7 cpu and a intel gpu graphics ...

As the V989 has abandoned by Onda, the v989 Air will be to ... now it´s the Fk&%$ dual boot tablets fashion :mad:

Hi adrpat,

 

Thanks for your great contribution.

Onda had released 1.0.6 Office rom for V989 air. Could you please review and cook new custom Rom based on this new official rom?

Thanks

Just noticed after applying update the firmware version now shows as 1.05 and not 1.06 ?

just a build.prop detail. with a root explorer, find build.prop file in system and edit him to 1.06

 

ro.product.firmware=V1.0.5

 

to

 

ro.product.firmware=V1.0.6
