How to extract and repack S8 system.img? - Samsung Galaxy S8 Questions and Answers

Hello,
I tried to extract the system.img of my S8 but it didn't work.
I tried the Auto Tool and several different tools but none of them worked for me.
How are the devs doing their roms with extracting and repacking?
I want to customize my system but none of the roms fitting to me.
Please give me an introduction how to customize /system/app /system/priv-app and how to repack it.
Thanks

system.img from ROM zip files?

Hi,
I was wondering if there was a way to convert .zip files of ROMs/themes into system.img files so that they can be booted up via the android sdk emulator?
I've seen that it's possible to launch system.img files in the sdk emulator, but after searching for quite some time I wasn't able to pinpoint a method for creating system.img from update-cm-4.2.12.2-signed.zip (for example).
Thanks.

i made a post about those system.img files earlier here: http://forum.xda-developers.com/showthread.php?t=609090
in theory it's possible using the mkfs.yaffs2 tool, but i'm not sure whether the emulator supports danger SPL roms, because the system image file size is limited in the emulator as well...

it's the mkfs.yaffs2 tool
see usage here:

Hi,
Thanks for the link, but I'm quite a newbie in these things, so could someone please walk me through process? I've downloaded the archive in the link.
How many times do I unzip it (I can unzip it up to three times and then I get 5 files numbered 1 through 5)? Where do I paste it? How do I use it? The explanation in the other thread was slightly too complicated for me sorry
Thanks

Get someone to Nandroid backup the ROM.
It creates a system.img, recovery.img, data.img, cache.img and boot.img.
Not the easiest method but it works

There are ways to repack it (I've never done it myself, but if you search, you'll probably find some tools), but there is an easier way to just install a font: package it up in a recovery-flashable zip. A guide on how to create recover-flashable zips can be found here.

[Q] Understanding Meta-Inf folder

So i pulled stock system folder and deodexed, zipaligned and signed.
Wanted to try flash it by twrp. So i copied one of custom roms meta inf folder but i get sysmapfile error.
Created certificates with signapk but there is no update-binary and update-script file. So i searched and learnt sth about update-script but what is exactly update-binary do? How can i edit for my rom or create one? can i use one of them with all devices rom?
Btw editing update-script didnt solve my sysmapfile error. Can someone guide me about meta-inf folder? All other articles just tells using another roms meta inf but it simply didnt work for me.
The update-binary file is different from one ROM to the next. For example, a CyanogenMod binary will be different from one in a custom ROM based off stock. In general, look at http://wiki.cyanogenmod.org/w/Doc:_About_Edify for an explanation of what the binary is. You will need to pull a binary from a custom ROM based off stock, preferably from the same version of Android.

Stock Boot Animations Needed

Working on something and I'm in need of a few files.
I've searched around and havnt been able to find them so I came here. This way I won't have to download the entire firmware and extract it.
I'm in need of these files:
bootsamsung.qmg
bootsamsungloop.qmg
shutdown.qmg
I need all 3 of those from Sprint and T-Mobile.
If you are on one of these firmwares, could you please copy them from /system/media and upload them please
Links to some really cool custom animations (qmg only) would be awesome too
Thanks

How to extract system.img from Android 8?

Hi there, I tried to extract system.img with ImgExtractor and all tools that based on that program, but I had no luck extracting it.
It always only extracts 226mb of /system/app folder and then quits with
Exception EListError in module ImgExtractor.exe at 000164F6.
List index out of bounds (48136).

There are custom roms available, how do the developers extract and repack the images/zips?
