RIP my STB. It's hard bricked now due to eMMC changes as standard partition. I am not planning to buy again, because their ecosystem is really limited. I am looking for a vintage computer instead under $70.
@jimedrand RIP. ig it should still be flashable as long as your STBs emmc health are still at safe level. though you may need to having a UFI box (for flashing directly through emmc) which you sure it won't afford to buy that tools, you can ask it for help flash instead at the nearest service centre if you intent to recover these stbs.
@kitsune Hard brick means there’s a short circuit happens in the eMMC modules. So, unbricking it requires effort and method, but somehow it’s closed (I mean, not much information about that, even though there’s a bunch, some of them are outdated).
