Installing cygwin:
2. Choose Install from Local Directory
3. Choose where to install cygwin, to make it easy for you then let it be installed on C-drive
4. Brows to the Local Package Directory, it's under cygwin packages in the extracted archive directory, as shown below
5. You will be greeted by warning, hit OK
6. Click on the arrows as shown below until all packages change status to Install and hit Next
7. Complete the installation, no more changes are required and you might get a Windows error when installation is complete, just hit Cancel
Re-packaging the firmware:
1. Make a and rename a folder/directory and extract the firmware tar package to that folder or simply open using a compression utility like 7zip or winrar then highlight and drag the files to the new folder. It's easier to make the directory on drive C if you are a windows user.
2. Extract the Empty_dbdata.rfs_file archive and copy the extracted dbdata.rfs to the same folder
Note:
All command for packaging and creating a single tar.md5 file(3 commands) can be executed as one single command as follows with PDA as example:
and so on..Code:[B]tar -c param.lfs zImage factoryfs.rfs dbdata.rfs >> PDA_JS5.tar ; md5sum -t PDA_JS5.tar >> PDA_JS5.tar ; mv PDA_JS5.tar PDA_JS5.tar.md5[/B]
We have by now repackaged a firmware of 1 tar file to 3 tar.md5 files, these files are now ready to be tested before flashing or sharing.
Testing the tar.md5 files (Windows):
Start Odin and load PDA, PHONE and the CSC files without connecting the phone to any USB port and hit Start and look at the massage panel of Odin and see if your packages are valid, if they are not then you haven't repackaged the files right, and you need to start over.
Sharing the repackaged firmware:
I have many times seen our members upload and share firmwares that are not compressed, this is not good for two reasons:
1. The file could be corrupt when downloaded, and there is no fun in flashing a corrupt firmware, this can be avoided when extracting a compressed firmware. A corrupt archive cannot be extracted, and thereby you will know that your downloaded firmware is corrupt.
2. A tar file is not a compressed file, it's only a package that contains file(s). Please take a look and see how all the extracted files are almost equal in size to the tar.md5 files
If you compress your files before uploading them, then file(s) size, upload time for you and the download time for them you are sharing your file(s) with will be cut in half, take a look to see what I mean
We have by now learned how to repackage firmware(s), use them and share them without worrying about re-partitioning.
We can now repackage and remove boot.bin and Sbl.bin in any leaked or official firmware that is already split in 3 files, that may disable Download and Recovery modes of our devices.
Good luck repackaging, flashing and sharing your firmwares..
