Trv,
You need 2 firmware a full version named "Full.bin" and a repaired dump file you want to merge named "Dump.bin".
Put them both in the s1fwx folder.

Open notepad and paste this:

@echo off
::make script from full.bin to recompile from
s1fwx s full.bin > merge.script
::extract files from the full.bin
s1fwx x full.bin
::extract files from dump.bin overwriting files extracted from full.bin
s1fwx x dump.bin
::rebuild full firmware with files from dump.bin included
s1fwx a merged.bin:afi < merge.script
::delete surplus files
for %%t in (dump full merged) do ren %%t.bin *.bak
for %%t in (script ap fw bin bi$) do del *.%%t
ren *.bak *.bin

Then save as Merge.txt.
Rename the file Merge.bat and place in the s1fwx folder along with the 2 .bin files.
When you run Merge.bat it will merge the 2 .bin files and create a new one called merge.bin.

Hope this helps.
