Locking down the Clear iSpot

If you’ve rooted your iSpot you’ll want to make sure you lock it down. If you used a pre-made configuration, make sure it disable OTA updates.

UPDATE: I’ve removed my original instructions that said to set the ENABLE_INB_* settings to YES. That was incorrect, sorry! The title in nat.conf was misleading and I jumped the gun. Revert those changes if you already set them to YES.

Also, it may also be possible to prevent or alter how the factory reset is done. This could help protect from inadvertent resets while in a bag, for example.

There’s a lot of interesting binaries and scripts on the devices, such as /bin/fota (Firmware Over The Air flashing I think), a serial console that dumps you into a shell without any login (see the inittab), flashing programs, the two management apps launched via inetd, etc. Lots going on.

Cracking open the case reveals what could be a serial/JTAG port, two unused antenna ports, and some other goodies.

But back to the point… can anyone else see another way for updates to be pushed down?
