I decided to release a 7.0.1-based build before fixing the "not being able to power on by remote" issue for V3_1 board. This bug is related to broken u-boot and not easy to fix without breaking features for other boxes, like CEC wakeup. The bug is also present after upgrading to cyx_MXQ_8189etv_8g1g_kodi_16.0_160419.
kszaq do you have a link to that firmware? Since the latest I can find is the cyx_MXQ_8189etv_8g1g_kodi_addons_160116_SD update one...
Edit: nvm found it at geekbuing
Edit 2: Even with the new firmware bdinfo still shows only 512MB ram...
I did however got a responce that the factory still claims it's 1GB, but 16-bit instead of 32-bit...
While the info of the bootloader states that it's 32-bit, so still something is really screwed up...
