Neomode Custom Rom MK802IV / MK809III 2.1 BETA RK3188-T and RK3188

[babnik80]

Hi Neomode, any update on 3188t gpu overclocking; Is it possible;

[neomode]

It should Work. But you get not more Power with it. The Best Combo is Overclock DDR and CPU.

Default sound to mediatek

Hi all,

in my 802IV with 3188-t I have some flickering but the most annoying thing is that sound defaults not to HDMI but to Mediatek (it comes from my F-10 pro) so each time I power the thingie up I have to go to settings and change it.
Any chance to solve it?

Neomode: you suggested using DDR overclock, I tried to use sam overclocked with 1.7 but to no avail;should I try it with this 2.1 just putting the overclocked kernel in place of yours?

Thank you

Yes you can use a Kernel from Sam321.
I make this firmware to use old kernels with T CPU.

When i try gpu oc kernel, i get always the same antutu 3d score, at about 2050. And in dmesg i see mali freq at 446 top. That's why i think that gpu oc isn't possible. Have tried it yourself neomode with your mk802iv stick? Any results?

[Rkman]

Hi, you can partially resolve the blinking/flickering problem by connecting the tv stick directly to the hdmi tv port. (without using the cable)

For me the the screen now doesen't go on and off every 2 sec; but for every overclocked kernel I have an image distorting problem (lesser in 1080p and overclocking the gpu)...

Same problem of Gianca here (RKM 802IV with 3188-T), even with the stick directly connected to TV.
Neo 2.1 in combination with oc by Sam works really good but black screen coming and going every 2 sec.
Neo 1.9 with no overclock instead is very stable and with no lags: but I am sad without overclock..

P.S. Gianca stesso problema qui..con la Rikomagic 802IV e proc. 3188-T

[ggforce]

it is possible that on my mk809III with RK3188-T where there are problems with this NeoMode 2.1 for flicker problems, and where the clock does not exceed 1406 MHz, I can run "justXBMC_v1.1.1_x7" which is for Minix Neo X7? ?

[shyguy]

Would there be any reason why I can't flash my 16GB MK802IV to this old bootloader firmware? Attempting to flash bricks my device resulting in it being detected as Unknown Device.

[cledus]

Same here. Very stable but the screen goes black for a second from time to time.

Ok, after A LOT of tribulation, i had found a configuration that (probably) have stopped every major problem in video playback.

This is my config:

MK809III v2 (AP6210 and RK3188, not the "T" one)
Neomode Custom Rom 2.1
Kernel included in the NCR, overclocked with rkpatchomatic, with CPU freq steps, in GHz: 1.00,1.20,1.42,1.60,1.80,1.92 GPU freq set to 798 Mhz and DDR set to 800 Mhz (that with DDR, i guess, it's an effective 1600 MHz)

This is what i get in Antutu, but i had to clock the cpu to 1,2 Ghz min/1,8 Ghz max because at 1,92 was unstable...



Anyway, i can give you the modded kernel, or the rkpatchomatic source file i've changed.

I'm testing it now, with the largest 1080p movie i got, attached to the TV's usb, from a 3TB HDD... and so far it is going really nice!

Bye guys!

What kernel did you have? What is NCR?

[FrankieDedo]

What kernel did you have? What is NCR?

I have patched ,with rkpatchomatic, the base kernel included into the NCR = Neomode Custom Rom

[mymkv]

so anyone was able to find good working combination of rom and kernel without fleakaring and working bluetooth with wifi?

I've watched a whole Full HD movie without any blinking or choppiness, and wifi is good (but i have the antenna out of the case) i didn't tried bluetooth yet, but i think it should go well. I'll test some more and i'll post everything i find

I've noticed that the flickering was probably caused by an insufficient power source... i'm buying a 3A PSU then, just to be sure

nice. I assume you are using this rom 2.1 with which kernel ? can you please post download link?
