extract_firmware not working but can use unsquashfs-4.2
« on: April 02, 2015, 03:44:29 AM »
hi everyone

I have managed to unpack some my .bin file using binwalk and then unsquashfs 4.2 official from src/other/

The problem I have now is how to rebuild the squashfs-root into a workable Firmware? any help or straight up 'not possible' answer would be great :-)

Info:

Code: [Select]
binwalk -s miwifi_r1cm_firmware_4ee06_2.1.7.bin

I am sorry my friend, but as others will attest, I'm already over-committed, so won't be able to help you. To date, I've not seen anyone else around who can assist in these matters.
