Rockbox Ports are now being developed for various digital audio players!
I tried for a search through this thread (i have read all of it, but some of it was quite a while ago)has anyone tried disasembling the actual firmware installer (regardless of what firmware is inside) in order to try and follow how the firmare makes its way to zen vision? it may reveal when and where the checksum is done,apologies if it has already been triedkeep up th good work too
Could the firmware be packed using a program like morphine, or some other file packer? As I understand it, these programs allow a file to be compressed/encrypted/obfuscated while leaving their ability to run unchanged. File packing is a common way to get malicious code past virus scanners, so could creative be using the same method to keep their firmware secure?
The show stopper is that the executable code within the ZVM firmware is encrypted/encoded.
Great work zook! Â
If you look at some strings in FRESC, you see that some files (devopen.c, devdraw.c, font_freetype2.c, fblin16.c, ...) are the same as in http://svn.neurostechnology.com/listing.php?repname=Nano-X&path=%2Ftrunk%2F&rev=4&sc=1So they are using the MicroWindows (Nano-X) engine.
According to 'Copyright MGC 2004 - Nucleus PLUS - ARM925 TI v. 1.14', Â 'Accelerated Technology Internal Use Only - Serial Number: NP0000' and 'Copyright(c) Founder Corporation.2005'; code from these 3 companies was used.And then you have these strange strings: 'CTL:N0MAD|PDE0.DPMP.' and '1sN0TM3D az u~may th1nk*Creative Zen Vision:M'.Could the last one be another encryption key, zook?
