Hi there,
what has been your original OS, prior you carried out the update attempt?
In case your OS was1.17 or lower, you need to update the bootloader
first in order to read the compressed OS2.0 file. I updated from OS1.3
to OS2.0 with no problems at all.
I searched the net and the EMU manuals, but couldn't find a way to reset
your MP-7.

Instructions:
1 - reboot XL-7/MP-7/P2500 holding down Home/Enter
2 - if you already have 1.17, skip to step 6
3 - using E-loader, download commandprep10.dli
4 - when asked to "Replace bootloader?" press enter
5 - when instructed, reboot XL-7/MP-7/P2500, again holding down Home/Enter
6 - using E-loader, download command118.dli
7 - follow prompts
