split_updata.pl.txt 3.39KB 1700 downloads The webserver wouldn't allow me to upload a .pl script so I've given it a .txt file extension. You'll have to rename it to just split_updata.pl
Useage: perl split_updata.pl updata.app
It will extract 25 files. Some of them are obvious, like the boot and system images, but there are many I don't recognise. For the time-being I've used a .mbn file extension for the unknown files because I think they might be appsboot.mbn, oemspl.mbn, amss.mbn and such-like. If you compile the CodeAurora AOSP code you'll notice it produces appsboot.mbn and appsboothd.mbn alongside the boot and system images. I don't know what they are but they have similarities with some of the files in the UPDATA.APP package.
I don't often use Perl so I'm sure there are better ways to script this. You are more than welcome to make improvements. And it would be great if we can identify what each file does.
Note: This script will only unpack the file. Repackaging it would be very tricky because it contains checksums that would have to match.
*** UPDATE ***
There is now a much improved version of this script over in this thread. Please use that version as it's far more stable and robust. Full kudos to ZeBadger and all those involved in enhancing it.
