afptool: can't unpack RK3188 update.img #10
Description
I don't know if this is expected with this kind of quite old RK3188 images, but I get:
$ afptool -unpack update.img tmp/
Invalid header magic
UnPack failed
The same img is correctly unpacked by @naobsd's rkunpack (https://github.com/naobsd/rkutils), which gives:
$ rkunpack input-update.img
