Finally, all working. Use the build v1.1 from post #1 and change kernel/resource shuai #10 in folder rockdev/Image before flash.

Thanks for the hard work OMA!!

I finally managed to install the ROM. It feels smooth and looks cool. But it has some issues, like some random music reproduction,  google search box starts up whenever he wants, audio doesnt works with headphones (just with the speakers), battery life is really short (it lasts like 3 hours, , after fully charging). And by the way, why 3D graphics have come down so drasticly? In antutu benchmark shows a loss of 2000 points, and in 3d mark 3000 points.

So my question is if this last version 1.1 with that kernel fixes all those problems.

Thanks oma!

PD: Whats the battery capacity of this tablet? 6700 mah or 8200mah?

And another issue is the one of brightness, when is low brightness you can't see the screen at all. This is specially annoying when activating power saving mode.

Does this last version solves that too?

Thanks in advanced OMA!

Hi krash!

As you said, most of them are fixed in the new version 1.1 (with the new kernel), and all I can say is that its quite surprising the great effort developers have made in this second built, its much more stable.

Almost everything works, but we still have the problem of the 3D graphics performance, as well as another bug while listening music with headphones; it seems like the speakers activate at the same time too, so I really can't use them as I annoy other people.

I hope it will get fixed soon, this is the best ROM I've ever seen on android.

Cheers and congrats to the developers!

Thank you guys for feedback!

We do still not have the kernel sources ... re-enginiering a kernel is an exhausting job.

However, when we can force ifive and other companies to bring their LP builds into the field this is an benefit for all users.

Air battery has 8.200 mAh (as advertised). Confirm that with latest kernel the headphone bug is back. Brightness works now.

In LP there is a new mali driver, which is btw one of the reasons why we can't make the KK kernel work. So, no influence on that.

As for google framework crash, pls make sure that you do a clean install.

Thanks for the response OMA!

I have to recognize I've never expected to have Lollipop in such a cheap (and at the same time powerful) tablet. The bug of the headphone is the only real bug, the rest of fails (as you said) can't be saved as your team can't handle it without the official drivers and help from the manufacturer.

And by the way, why did the kernel maximum speed is up to 1.6ghz instead 1.8?

Thanks in advance!

 

PD: I asked about the batteries capacity because it shows in the stats of battery use that its capacity is 6700 may (I guess its a bug)

Android does not really help showing stuff provided by the kernel. Especially for the Ricoh619 PMU. Additionally LP needs a few cycles to learn the stats.

Typical limitation for the kernel is 1.6 GHz. Above the tab may no be stable enough.

Installed the update but... The only bug left is the one of the audio and headphones (they work simultaneously when plugging any kind of headphones). For the rest the ROM is simply the best, fast, stable and beautiful.

 

Let's see if it can be fixed in the next few days...

Thanks for the hard work!!!

Headphone mute works well. You need to use the kernel coming with the v1.1 build.

What i have right now is the v1.1 with the kernel called "heshuai five". And after it I installed the update of the Bluetooth. So, do I have to reinstall the whole ROM (with the new v1.1) and after it install the Bluetooth fix?

Thanks again OMA!
