Unpack-pack firmware, possible?

yeah that's a good reason. IF someone can unpack it. But wanna ask. How do the vkp patch like sysgfx patch do? CMIIW when we apply that patch we add some byte to the end of our main firmware, right? why with that we still can flash it to the phone?

i'm with you guys, i am determined to write my own main. i agree that if you can patch a main firmware then you should be able to write one. i mean if the manufacturer ,or whomever does it, can write a firmware that works regardless of what the checksum is when they create it; so can we? i am willing to waste away all my free time with this ... fall into disrepair, etc. etc. so on and so forth :D there has to be someone who knows how 'they' compile the main files, and therefore how to decompile/recompile them. any takers?
