I figured out how to hack the EBR1 on mediatek MTK6572 to increase userdata by merging the fat and userdata partitions. Unfortunatly, this mod does not change the blocks maps, even when editing the scatter text to match the EBR1 hack mod. Here is the post on how it is done.

After much searching, finally found out that the blocks maps are probably setup via preloader.bin, which tells /proc/dumchar_info what the blocks are and sizes. Well now I would like to figure out how to hack the preloader, either the bin or preloader_and_dsp, to edit that sections that it matches up with the modded EBR1. Just can't find any information, looked at the preloader.bin and preloader_and_dsp in hex editor and emacs, but that doesn't help me much, am able to see the section where it tells EBR1, preloader, userdata, android, etc... but can't make out how to change those hex values.
