how to disable the annoying bad checksum message?
jessy:
i tried to edit the rockbox.sansa , i put the file in the clip zip, and now it bother me with bad checksum...i know that the file is different, let me load it!!!
Why it blocks me? How can i disable this check?
saratoga:
My guess is that you would need to edit the bootloader and then flash it to your device.
Why are you even having this problem though? Generally one edits the source code so that any edits happen before the checksum is computed.
jessy:
i'm just exploring what i can do, i'm not a developer.
So, if i try to change something in the code, and i want to try it, i have to reinstall the bootloader every time...
There is somewhere a bootloader that doesn't block the system if the checksum is different? Or a step by step guide to remove this check?

No, if you edit the source code the checksum will be correct and thus you will not have this problem. You probably never need to edit the bootloader unless you're doing something strange or actively working on porting to a new device.

No, and no. If you want to do this, then you'll have to dig into the code.
But again, why do you want to do this? I can't think of a reason why you would want to.
wodz:
Do you edit *BINARY* rockbox.sansa (in hex editor or something)? If so it is no surprise that chacksum is incorrect. This check is exactly to prevent such situation. Properly compiled binary (with source changed or not) will have proper checksum.
