Unpacking, Modifying, and Repacking Rikomagic ROM - Android Q&A, Help & Troubleshooting

Hello,
I am having some serious trouble modifying a ROM. I download the entire ROM in the form of an .img, and thanks to a reRepacker am able to unpack the contents of the rom, each part into individual .img files. I then use file ext4 explorer to open system.img, then save as an ext4. I then use ext2 explorer to open the now ext4 system.img, and I save the contents in a file folder within the unpacked folder. I make all of the edits I need, and then use WinRar to "add to archive' the file folder as an .img. Note that it compresses the size of the file bu about 40%. I then throw the dump folder into the repacker and out spits the new "modified" rom ready to be flashed to the device. I then use the batch tool to "flash" the compute stick. Flash being a relative term because it does not get past the boot image. EVEN IF I EDIT NOTHING and just convert to ext4 to ext2 and then to .img it still won't boot. Maybe this is because I am going from an ext2 to an image? When the file is supposed to be ext4? I'm not quite sure, hence why I ask here. Anyone have any ideas?

Help Need Meta-inf

So, my phone recently got soft bricked....
I had the tar file of the XXELK4 leaked firmware and i extracted it, unpacked system.img.
Mounted it as ext4 and extracted the contents.
I want to make a flashable zip file from the system.img contents.
I made a folder called system. In which all app, bin, etc and other folders are.
Then i copied over the boot.img from the tar file...
Now, i need the meta-inf. I tried using some meta-inf from other roms, and removing the aroma functions from them.
Then trying to flash..
I get only a bootloop.
So, could someone provide a clean Meta-inf consisting of only the updater-script and update-binary??

[Q] Files in a nandroid back up

Ive done a backup on my phone and created a flashable zip (update.zip)
Now im playing around with dsixda's kitchen and trying to extract the system.tar, however it fails most likely due to fact the the system.tar is empty
the files in the archive are as follows
Meta-inf -- <folder>
boot.img -- <8192KB>
image-edify -- <1KB>
system.ext4.tar -- <0KB>
system.ext4.tar.a -- <976,563KB>
system.ext4.tar.b -- <68,151KB>
By the looks of things it has split the system.ext4.tar because its over a gig
How can i compile this into one file or one image so that the kitchen can read it, I'm on a windows 7 PC but i can run linux in a vbox if necessary.
Thanks
Try using the zip file in your input folder.
dsixda's kitchen should be able to extract from it

Click to expand...
Click to collapse
Already tried, it comes back saying its deleting the part a and part b files and then says the system.ext4.tar isnt a valid archive.
Is it a stock rom?
If so, download the firmware from sammobile and put the tar.md5 file into your input folder (after removing the .md5 suffix).
Thats worked for me in the past....
It is stock, but i have removed the bloatware, installed a few mods, i was hoping to use this particular one really as a base. Ive already played around with fully stock and i kind of broke the whole thing
I'm not too sure then unless theres some tool you can find to merge the 3 tar files into 1...
Never had to do it so I'm unable to suggest anything I'm afraid.
