How to unpack and repack system.sin?

[sourabh]

Hello Friends,

I downloaded 4.1.B.1.13.ftf file and extracted using winrar. I got .sin files.

Then using flashtool sin editor I dumped the data in system.sin file to get the system.yaffs2 file. Then I extracted system.yaffs2 file to get the inbuilt apps folder and removed some apks from it.

Now, Is it possible to repack the system.sin file after removing the unnecessary apps from system.yaffs2 file?

Please help.
