Blob tools is nice and simple to use
To extract a blob:
1. Download the ROM.zip or other multiple partition blob file and extract the file called 'blob' (Or 'recoveryblob' or whatever..) out of it.
2. Place the 'blob' in the same folder as 'blobunpack.exe' (You can rename it if you have multiple blobs and need to distinguish them)
3. Open up cmd.
blobunpack blob (Or the name of the blob, no extension required)
Let it do it's thing for a moment...
5. You will now have many blobs with different file extensions, each of these file extensions is a different partition of the TF.
EBT is the bootloader
SOS is the recovery
APP is the os, and etc...
