T-R42 2.0 Board Firmware by lewy20041

[picarddontoro]

This firmware is ok for my Android Box B351 V2.0

Hi lewy20041,

thanks for your work.

This firmware is the only one that works for my box (B351 V2.0).
There will be a future version with a kernel enabled to overclock the CPU / RAM / GPU?
Wasser kernels can work on my box?

Thank you

Update 1: lewy20041, I found in your first post the OC kernel, I'll try it. Thanks.

Update 2: I tried to flash your OC kernel but Rockchip Batch Tool 1.7 show "load firmware failed!". How I flash kernel?

I finally succeed.
Put device into flash mode, run RKAndroidTool v1.37 (not RKBatchTool v1.7) and enter as a only line:
[check on], 0x00004000 (Address column), kernel (Name column), kernel.img (Path column)
Where "kernel.img" is the kernel file to flash.
Finally, click on Run.

How did you do this ?

there are no instructions for RKandroidtool

Which kernel did use

Maybe post a tutorial

The kernels are in the first post (OC Kernel Pack).
I used 720p_cpu1.8_gpu798h_ddr800.img without proplems on my B351 V2.0 box.

The procedure I used is the one described in my previous post.

RKAndroidTool v1.37 is present in the wasser 's firmware in this post:

Wifi Problem

Hey Lewy, i'm having really bad wifi problems on the rom. Is there anything you can do? When my wifi works I get maybe .3 down and .3 up. The connection is to slow for anything especially streaming home videos. I've reinstalled twice, changed out kernels.

[stubuchy]

HI lewi,

I have one of these and on your rom it runs well, would it be possible to get the "hide home bar" working on this rom?

thanks for your help!

So is the wifi working well for you? How many times did you install or reinstall?

[timenewton]

Hey, Lewy, will there finally be an Update?

Rom

Lewy

Great Effort with the ROM , possibly the only custom made ROM available . I Have the 1.8 Ghz OC kernel @ 1080p , however this runs slower than my other Android devices ( Samsung Galaxy Tab 7") , despite the Device having better hardware spec

For all those having trouble with Wi-fi you need to configure your WIFI settings on the Router web interface and change the Spped settings from 300 Mps to 54 Mps

[ollie26]

Sup Lewy.
ROM works great. However.. Your OC 1080p kernels give me poor play back in xbmc like stuttering no h/w acceleration but my xbmc version has h/w. 720p HD works fine with your justxbmc just the 1080p kernels. Android UI is a little laggy v 720p when using the 1080p_cpu1.7_gpu798h_ddr720 kernel

None if the kernels at 1,8ghz work for me. Box gets stuck on boot logo

Xbmc crashes on 720p&1080p playback using 1.7,OC kernel.

Also if I use the switch resolution option in advanced settings I lose my 1.7ghz OC and it defaults back to 1080p @,1.6ghz

Appreciate your work
