T428 Study and Research on Experimental Firmwares

[Guest]

That kernel and boot.img are both from stock 5/21 4.2.2 t428 rom................. I am uploading a fixed version now with the same + your changes for wifi

You will have to upload actually, I made the changes to system.img but cant get mine to boot anymore after siwthcing out modules. I tried to re-dl stock p9 rom too to try with that boot.img but the link has gone to shit an download will take 14 hours. So i wont be able to help much

I will upload the pipo porting with the wifi working today

Just tested your changes manually though and the wifi is def working! Nice job

now we must engage on the bluetooth and hdmi screen settings (the bluetooth is working on cube experiment)

the bluetooth for me is not a big problems for now, i use DroidMote and i can have all external input devices simulated with my phone. (mouse, controller,multitouch etc. etc.) In this mode i can test all with different roms, devices and OS.

For the hdmi screen settings, if someone has already worked on this component is welcome.

On these android hdmi sticks, it takes grinding effort to test things. It is not as simple as for the standard android devices. The cause depends on the form factor, and for example, by the fact that I have to have a second monitor but the usb attached to the PC. is very uncomfortable to work on these devices.

i'm uploading the pipo rom for t428

The videos and all the rom of pipo work very well.

Now i have only problem on bluetooth and screen zoom functions.

Bob do you have a suggestion for screen zoom functions ? this is a feauture only of android hdmi sticks. Standard android devices don't have this usually.

And this is the problem with porting tablet ROMs.

To add zoom to settings much smali code in many places has to be edited
settings.apk
settingsprovider.apk
framework.jar
policy.jar
services.jar

NOT easy to do!

But I can tell you manually how to set scale and set HDMI resolution
You can write to these files

HDMI resolution:
/sys/devices/virtual/display/display0.HDMI/mode

Here is a script I made to on boot set HDMI resolution to 1920x1280.
Put it in init.d folder if ROM supports init.d
If no init.d then type this in Android terminal emulator:
echo 1920x1080p-60 > /sys/devices/virtual/display/display0.HDMI/mode

#!/system/bin/sh
# Set HDMI resolution
while [ ""`getprop dev.bootcomplete` != "1" ] ; do sleep 1; done
echo 1920x1080p-60 > /sys/devices/virtual/display/display0.HDMI/mode
# done

Screen Scale:
Same place but file is called scale
echo xscale=100 yscale=100 > /sys/devices/virtual/display/display0.HDMI/scale


Also as I recall there is a setprop command for scale you can add to build.prop. I never tried it but I know some of Lewy's ROM did that.

FYI if you get an error writing to these files then you must set permissions for all the folders in the chain to allow write.
Also note not all ROMs call the HDMI folder display0.HDMI. It could be called just HDMI etc. So you may have to go look with a root explorer.

Thanks bob your answer was very comprehensive.

I don't like patch standard framework.jar and services.jar for that reason i started with this rom. At this point we can make a little app or script that can change hdmi settings.

thanks thanks

my problem is that i don't speak english very well, but I want to make everyone understand that if we need other things that are not standard, we can make for all external scripts or apps uninstallable if we have problems. Android in some positions is untouchable at risk of ruining the performance and the normal operations.

I am good and we do have APP developers here that can help us. Just let me know what you need help on and if I can find a way to do it, I will try. As you know I am always super busy making new ROMs for devices that need them and are not rooted.

thanks BOB, I know that you're a great person. and for this reason I am working in this way in your forum.

let's see before how goes the basic tests on this rom by users and then together decide what to do

the videos for me in this rom are good.

[Finless]

If you PM me links to your ROMs when you put them out, I will host them here on freaktab for people to get fast download.

Bob

[Guest]

this rom is a porting from the pipo M9 05.16 4.2.2 rom

please test the video performances in all video player.

Have u been able to run antutu? I get restarts every time even with CPU limited to 800mhz. Have tried 4 differ power supplies

Have u been able to run antutu? I get restarts every time even with CPU limited to 800mhz. Have tried 4 differ power supplies

i run antutu only with the external power supplies like all the rom. Antutu work in all the roms only with the external power supplies.

my score is 17420

today i want repack the last 4.2.2 27.05 pipo as CWM zip. In this mode you can swap files easily

[Guest]

This rom is based on last 4.2.2 for Pipo 27.05.
the rom should be installed using CWM recovery.

copy the update-signed.zip to an external sd-card

Flash with the tool RKAndroidTool.exe only:

RK3188Loader(L)_V1.20.bin
parameter
misc
kernel
boot
recovery


Power on the T428 and in CWM recovery:
wipe/factory reset
install zip from external sd card
select update-signes.zip and install

Wouldnt all USB power adapters be considered external? What type are you using? I have tried From my t428, mk808, nexus 7 and nexus 4. Outisde of antutu restarting the rom hasnt given me one problem it seems stable but I feel like my t428 is either not getting enough power or its GPU cant handle the frequency that its running at (always crashing during the 3d scene in the field).

http://www.amazon.com/Genuine-Adapte.../dp/B00A72LC6C - Gonna order one of these I think
