Hello
Is it possible to turn on in the OS H3Droid resolution 720x480i?
Interested in the same resolu ...

480i mode has id 0, so it might work in theory, cant test at the moment. you would need to put into fex and build.prop, check what display mode script in h3resc is doing

from root shell (ssh/adb/uart):
rmmod usbtouchscreen; modprobe usbtouchscreen reverse_y=1 xscale=120 yscale=50 xoffset=20 yoffset=-30

of course you have to find correct values first. you can later att that line to /data/rc.local to have it executed on every boot

Hello everyone, I tried to install the new version of h3droid on orangepi pc, but every time I tried it, it was just a full color screen. I tried with old versions (1.3.3, 1.3.2 and 1.2.9) too, but they gave the same bug, I changed the memory card, but I could not make it work

I use ubuntu 18 to burn the image
I change the device in 00_conf and run the script
sudo bash 10_init_new_card.sh

am I doing something wrong at the installation?

Forgive my English (google translate)
