[Tutorial] How to change kernel logo (1st boot srceen) [COMPLETED]

We have 3 major works here... So I gonna to make it seperated
-1st post is HOW TO EXTRACT kernel.img (boot.img)
-2nd post is HOW TO CONVERT PICTURE FILE to BOOT.RLE
-3rd post is HOW TO REPACK THE KERNEL PAKAGE into boot.img
Requiredment
-Window machine
-installed cygwin
-the full boot.img/kernel (some kernel won't work because there is no full pakage/ i mean we can't)
-bootimg.zip (tool for UNPACK and REPACK kernel)
-boot_screen_logo_creation_package.rar
Thank and Credit
i- Credit to DooMLoRD Recognized Developer over most of XPERIA devices for his own tool and tutor that I learned before
ii- Credit to jimbo77 Senior Member for his tutorial that I used and learned and tool for unpack and repack
ii- Don't forget to give them a thanks meter
=============================================================================
Here we go
1-This section I will show u how to unpack and repack the boot.img
just see from original thread by jimbo77 from here and download the UNPACK and REPACK tool by him HERE
this is a fast guide from me:-
1-extract the bootimg-tools.zip into new folder (name it 'boot' folder)
2-move it into cygwin directory (cygwin/boot)
3- move your fav kernel into same directory
4-run cygwin.bat
cd /boot

}
5-Now, unpack your boot.img by running the following command:
./extractboot boot.img
Click to expand...
Click to collapse
If your output looks like this, then the extraction has worked correctly! Note that the Command Line string has also been read from the source file, this will be used later when you go to re-pack your file.
Your script folder should now look like this:
boot.img-kernel is the compiled kernel blob that was inside the source boot.img, if you want to replace the kernel with another compiled kernel image, you can replace this file with another one (but leave the file name the same)
boot.img-ramdisk.gz is the gzipped ramdisk image which has been split from the boot.img, you should leave this file alone.
The “out” folder contains the EXTRACTED ramdisk, and this is where you should make your changes to the ramdisk.
Important Note!
Remember, when editing files in the ramdisk through Windows, such as init.rc, Windows notepad will not format the files correctly, making them almost impossible to read, wheras Wordpad will LOOK like it is formatting the files correctly, if you save one of these files from the Wordpad application it will BREAK the file and it will no longer be able to be read correctly by Android. To edit these files you MUST use an editor such as Notepad++ which you can download for free.
AGAIN...
Special thanks/credit to jimbo77 for his excellent guide

So.. NEXT step to change a kernel logo is here
Requiredment
1-a picture what are u like to look into the 1st boot screen (kernel logo) (make sure it size/resolution same your device resolution)
2-boot_screen_logo_creation_package.rar
3-some infos and knowledges here
4-window machine like i explained on 1st post
My quick guide
-extract the tool.rar
-move extracted files into new folder (name it 'rle' folder without quote)
-move into cygwin folder (to make it easy to follow my simple guide)
-copy your own logo.png (a picture u want to use on a kernel) into same rle folder
(for 4 steps above it shold look like tis)
-now launch cygwin.bat
cd /rle
Click to expand...
Click to collapse
./convert_image_to_rle.bat logo.png
Click to expand...
Click to collapse
Ah...my mistake..don't forget to move/copy/replace new logo.rle into
C/cygwin/boot/out/ramdisk/here
if you done good...follow next step on next post (to repack your moded kernel)

Last step before you flash a new look kernel (boot.img) is
Repack your moded kernel
./packboot
Click to expand...
Click to collapse
One thing to note that people may mention in other guides, is that when packing boot.img files, you will usually have to declare a base address, and a command line to the packaging tool. This set of scripts reads the existing command line and base address from the boot.img file you originally provided at the time of repacking, so always make sure you leave your original source boot.img file in the folder and do not re-name it after extraction, your newly created boot.img file will be named boot_new.img and will NOT overwrite the original.
Done! If your screen looks like the image above, then you should now have a freshly created boot_new.img file, ready to be flashed to Android for testing, you can now go ahead and flash it through FASTBOOT one thing I'll recommend though is to first do

I need this for extra (extra thanks..)

[Stock Apps] Samsung A03s Stock Apps Extracted from stock ROM

Hello Samsuns A02s users,
I know this forum section is for Samsung A02s but I did not found Samsung A03s forum here on XDA. But you can still try installing this apps on your A02s.
Here are the Stock Apps extracted from Samsung A03s stock firmware SM-A037F_INS_A037FXXU1AUJ2_fac.zip. (SM-A037F)

Google banned the access to files due to abusive downloads and removed the files.
To prevent unnecessary downloads I have restricted downloads. Please request for download if you want it.
If anyone want I will upload it to Mega as well.

Hi!
I hope not to bother you, I'm new here and since there isn't a A03s specific forum, maybe I could find some help here.
I have an A03s (SM-A037M) and I want to root it, but as far I know there isn't a TWRP for this model yet and I have never tried other ways. Surfing Google, I have found some tutorials, but I'm not sure how trustworthy they are.
Do you have this device too? If so, have you root it? Hope you can point me on the right direction.
Thank you in advance!

URI summary : Support for installing different ROM versions will be implemented, additional support for reading installation files. "First install - then patch" mode - a function that first installs the ROM using the means that the developers put in the installation package, and only then everything else will be patched based on the already installed firmware, as well as support for factory fastboot ROM formats that manufacturers provide for Miflash, for example, and etc
Summary of DFE-NEO. I'm going to study the wonderful script Zackptg5 Universal DM-Verity, ForceEncrypt, Disk Quota Disabler, which I used before the implementation of my project, in some cases my script does not work properly on some, those problems that are in DFE-NEO have already been studied and understood because for which it does not work properly, but to implement a set of problems, some parts of the code need to be rewritten, and this is not subject to manual correction by the end user.

Because the first alpha version does not provide for the reassembly of super, and re-partitioning. if you install fastboot firmware with super included. then this will cause problems, since the system partitions are located in slot _a and everything else will be installed in slot _b

No problem on Android 12 Motorola Qualcomm XT2215-4 SM6375.. For either. Dfe-neo I use every flash to kill decryption at first before I put my custom fstab.qcom in vendor after getting RW thanks to you guys. But I didn't know about the ROM flash tool. Two-part question number one what's going on with the source forge website all the files are missing? And part two, I've got a friend that has a arm7 device and the 64 binaries aren't working any clues there? arm7 binaries?

You're going to want that partition if you've got it on your device. As there's a lot of important white list xmls and some of the most important system apps they've got tucked away on that little system partition there. @LeeGarChat tool here is one of the few, in the case of his RO2RW that manages to see the almost non-existent system slot b that even imjtool says is not part of the "Motorola Group" or something that affect. I've noticed you don't need that one it's only 32 KB or something ridiculous you would think and you can live without it but I also believe it's what handles at least the touch on our virtual devices on slot b or possibly even the binary for switching the slots because I have had trouble without it. And that's a 32 KB m possibly unnecessary image now yours is part of the super block and housing important stuff, I'm sure he will work it out in the meantime you might want to just manually flash, then run his others such as RO2RW

Hi, If I flashed it through Odin, do I still need to supply the BL, CP, CSC? Thanks in advance.

A10 -> A9 9 on SD S10: the flashing itself works but device's now stuck on booting - cannot get to A9 recovery

Android 10 -> Android 9 on snapdragon S10: the flashing itself appeared to work but device's now stuck on booting - cannot get to Android 9's recovery for some reason which I suspect is due to a different partition layout (device's shipped with Android 9); tried to erase userdata with Android 10's recovery but still can't get it to finish booting. Any ideas?
