afptool: can't unpack RK3188 update.img #10

Open sphakka opened 6 years ago

sphakka commented 6 years ago

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
VERSION:4.0.2

Please note that your rkunpack from https://github.com/neo-technologies/rkflashtool does something different (only the BOOT section is extracted):

$ /home/utilz/android/tools/rkflashtool/rkunpack input-update.img 
rkunpack: info: RKFW signature detected
rkunpack: info: version: 4.4.2
rkunpack: info: date: 2016-03-29 20:03:07
rkunpack: info: family: rk31xx
rkunpack: info: 00000066-000311b3 BOOT                       (size: 201038)
rkunpack: info: 000311b4-2ade49b7 embedded-update.img        (size: 719009796)
unpacked

I'm confused ^-^

If I remember correctly, you have to run rkunpack again on the newly created embedded-update.img

$ /home/utilz/android/tools/rkflashtool/rkunpack embedded-update.img
