Core and firmware resources

Core resources

Necessary !!!

How to add init.d support
Two more ways to add support for init.d on the stock firmware:
The way to re-sign to tar.md5 on the phone in the terminal and the root is not needed for this.
Tools for creating CSC (WINDOWS)
fresh apktool 1.5.2
SuperSU-v1.30
SuperSU-v1.34
Option to reset the firmware counter (do not use for beginners, brick is possible)
Easy way to get the Russian language in firmware. If it is not by default (you need root)
How to dump bootloader

At the moment, all methods of rutting (except firmware, pre-rutted firmware) increase the counter of firmware. There is no safe way to reset the counter !!!

Cap on editing, wishes and suggestions write to me in QMS

Yesterday I tried to change anything in the sections related to data (system, ceche, hidden) during reverse assembly, the size is smaller by about 200 meters and an error pops up when flashing the modified partition.
So the matter is in some new way of encryption or protection for img from males.

Leonid53,
So it’s not difficult, just unpack the .tar.md5 firmware by removing md5 by simply renaming it to xxx.tar and unpack 7z, for example, with the archiver, or in the total commander. and neck.
In cache, there is no cache, there is no kernel there. The kernel is separately boot.img
To disassemble the firmware completely by linux (ubuntu)
Use this tool

This was written two weeks ago on xda, like AndreiLux was trying to sculpt something, but Samsy was coded and changed everything there, so unprovable containers were obtained.

I read about it, now I tried it myself, I want to solve the riddle.
The presence of the lost + found folder in each unpacked section is annoying. And the label for its creation is 01/01/70 3-00
Incredibly old 1970. As I wrote earlier, I met with this date in the firmware for the GT-9105 there is exactly the same timestamp for creating img files.

like AndreiLux tried to sculpt something, but Samsy was there all encoded and changed, so they were unshakeable tare

Because of this canoe from scratch, the kernel writes, half a way is passed ...

All our problems from ignorance - this folder is created automatically in the source code is written ...

Not only is it less, it generally has an incorrect format for the c4 sparse ...
I tried these tools:
make_ext4fs, mke2fs, e2image, img2simg, ext2simg
but to no avail, some of them are part of the Samsung source code for c4.
They say that you can create an image on the device itself, by
su
make_ext4fs -s -l 2764M -a system sdcard / system.img system
And it corresponds to the original, but for this you need a root, so the meaning is lost, the main task is to get root access to the firmware in the phone ...
In general, I see two ways, or find new dependencies to create make_ext4fs or how to emulate an ARM machine on pc and create binary images from a phone ..
By the way, with such tools as: img2simg, ext2simg you can not re-create the file system at all, they make sparse images from the usual ext4

And why is the time so old is on the date of creation, is not it just so from the bald? 1970)

I do not know

Guys, you're not looking there :)

Samsung made support sections>2GB per file
due to int64 (was 32) the file system has an additional 4 bytes in the block. Need to redo tulza and all. More precisely, they already exist. Look for better;)

Actually, I am. Alexeyuh is voiced. But apparently he did not believe me and decided to take out the branch: D

I made the block size when creating 4100, but this does not save, besides the block size, SELinux support is also needed, and in principle I also found
https://github.com/wonhongkwon/make_ext4fs/.../ext4_utils/log
, it also does little, and besides, I heard that in int64 systems the block size is 65536, but make_ext4fs cannot process a file with such parameters ...

Osolemio,
Duck tell me where to look, please.

Well, not so many places - everything is here:
https://android.googlesource.com/?format=HTML
You just need to know the dependencies for the Makefile when these or other tools are created ...
I advise you to look at tools such as simg2img, img2simg, simg2simg, ext2simg ...

Osolemio,
We can still try to stir up the command, I do not have much knowledge in linux but as they say I can.
Otherwise we will crawl around for a long time :-)

We ourselves have learned to use the utilities for pc platforms, it remains to find out the dependencies and parameters for creating the images themselves ...
I mean c4 (checout android-4.2.2_r1.2), because previous devices are already a completed step ..

[Osolemio]

There are many dependencies. Almost everything has already been collected, but has not yet compiled. Maybe a little bit later, if there is no need to transfer the half of the repository there. After this, everything should turn out, if you don’t forget to add something there: D I have these working days, so I don’t have much time to do.

And what parameters do you mean? physical block 512 length 2898264064

P.S. past devices in the past. Here among the dependencies and selinux.

in checkout android-4.2.2_r1.2 we need another folder system / core / libsparse

Thank you, I would have found it and added it a long time ago. And not only she.
