Are you high?
(adsbygoogle = window.adsbygoogle || []).push({}); Ok so my inbox is being filled with "how to you get past the checksum"

Written Tut


1. Calculate the original PKG's checksum in HxD


Analysis>checksums...>checksum-8

you should get F9


2. Go to your modified pkg


Calculate you checksum the same way(if your lucky you will get F9)



3. now what do you have, is it higher or lower than F9

Lower- would be a number like 0A or 09(any number)

Higher- F8-A1


4. Now u need to add FF in the place of any 00 you can find(to find some search for 00 with hex selected, not text string)


if its Lower u need to add a little until it goes over into letters again which the first one would be F9


if it is Higher than you need to keep adding FF's until you get to numbers, then follow the steps for a lower Checksum

No need to flame.... nor act immature. For the sake of things and not to start a "Shit-Storm" you guys are all sucking up to Shane, if this is the only way to stop complaining and flaming, we all are suck ups and will ditch Shane if he fails Winky Winky

And Shane no offense, just to end the flaming lol.

To bad none of you have realised that just fixing the checksum is not the only thing.

There are many of us on here that have fixed the checksums, guess what...Don't work...

It is a Signature not a checksum or header stopping you from copying it.

And NO before anyone ask, I don't know the signature...
