you can fix it by magic .

Hint : You have to edit something in the header

interseting : )

I was really struggling with hexedit ... If you think you've done everything like it's supposed to be done but the gif still cannot be open - I really recommend bless instead of hexedit!

Anyway, great challenge :D

Should be easy.

you can also use bless command to edit the header or hexeditor

check the header format has the hint says and edit the header format After that try to open the file and see what goes on, After that you can use the gif speed control online and slow the speed of the encoded message and finally your get the message but being encoded

I'd say it is not hard

Actually a really cool challenge!

Nice one! hexed.it helps a whole lot. Thank you javier!

File header missed a few characters.

too simple!
