Geeetech

I had the same issue when my A30 arrived (bought used one with this particular "issue" - blank screen). I just installed the latest version available for download from Geeetech website (A30_V1.38.59) and in addition uploaded to the screen's SD card the system folder, A30_S01_V1_38.bin file and the ...
