Add -e ./unpackhere to extract the files.

Write

Make a firmware patch containing 2 files:

patchv380 write stuff/exshell_bfu.sh /path/to/IMG_RFS_stuff.sq4

You need to then move the ???.patch file to /sdcard/updatepatch/???.patch and put in /sdcard/localupdate.conf:

[PATCH]
patchmd5=???

If you've already applied a patch, you might need -h V380E2_CA or whatever the ipcam's logs say you need.

Hints

exshell_bfu.sh is run as root at the very start of the update process.
