h60ga (deprecated)

As you can read here https://github.com/roleoroleo/yi-hack-Allwinner-v2/issues/270 there is a problem with the model h60ga with firmware release 9.0.27.20

This version writes 2 files to the "backup" file system which has very little free space. Any change to a file on this partition can break the boot of the cam.

So both the hack procedure and the unhack procedure (which write the init.sh file) can brick your camera. In this case, the solution is to use the unbrick procedure described in the wiki https://github.com/roleoroleo/yi-hack-Allwinner-v2/wiki/Unbrick-the-cam (the soft way).
