What steps did you use to have it working on h96max2 ? I burned a lot of different images to SD card, changed to all possible g12 DTBs, but each time I go to the update section and select the aml_update.zip from the card, it reboots, tries to load it, and fails with a broken android robot and just "Error!". It then reboots again on the android.
Mine is flashed with android 9 (from https://mega.nz/#F!enh1kIYD!FdtiQoEO0V4awyrEZRwUew from https://www.h96tvbox.com/content/6-Firmware-upgrade ), could it be the issue ? I read that some were using ddr3 instead of ddr4, how could I check this ?
