If it does we can probably hack this to death without ever opening it up.
Well what might be cool would be if the running android could be rooted (remotely, over network connection). And then install net boot loader / uBoot whatever for this ARM soc that supports iPXE / tftp network LAN booting. Then you could reboot into a network served image (like a liveCD disk, so RO filesystem, loaded into a ramdisk)...
From that point it would then be possible to totally reflash the SD Card without it being mounted or anything. And without opening the device and voiding the warranty sticker. However to get back to factory status would then need to reflash again the bootloader image for the SoC (whether it's uBoot, coreboot or something else more proprietary based android bootloaders, IDK).
It is something to consider for those people wishing to preserve warranty options / restore to factory / resale value on these device.
However another ancilliary benefit might be a capability to instead just boot straight off USB connected disk. Since you are replacing the bootloader anyhow. This would then also be another way not to need to touch the build in SD card whatsoever. And preserve it as a fallback legacy boot option. This sort of approach probably needs more experience hacking about. And to ensure that the bootloader is providing necessary pre-boot hardware functionality 'alive' for the later stages. Not to break necessary hardware support(s).
