how does some snapdragon have a unlocked bootloader but not usa lol

In the folders where you downloaded the rom, there is bootloader files that do the same thing.
[Samsung Galaxy Note 10+ Themes, Apps, and Mods] Eagle 3:
I flashed Dr. Ketan's bootloader but the Boot Warning was still there. Odin said that the flash was successful so either it doesn't have the Boot Warning removed or I can't flash it after rooting and flashing the ROM.

[Samsung Galaxy Note 10+ Themes, Apps, and Mods] asafegous:
I'm finding it difficult to explain myself here, but I'm trying to figure out if anyone can help me figure out at what pixel coordinates the boot warning message covers the larger image.
[Samsung Galaxy Note 10+ Themes, Apps, and Mods] Dante63:
The warning is written directly on the boot image, there are 2 boot images, normal state boots normal Boot, modified boots the warning, the next step is related to press key to continue which basically I'd drawn as top 0 and center...

What I do is basically maintain the names and simply use the same image of the normal boot and as for the warning, I completely make it black...
[Samsung Galaxy Note 10+ Themes, Apps, and Mods] asafegous:
If I want to use a custom image, I need to know what points to crop out to fit the original image. What are those pixel coordinates to make this happen?
[Samsung Galaxy Note 10+ Themes, Apps, and Mods] Dante63:
The boot image size, is the size of the screen pixels 3040 x 1440, that's for note 10+, not sure about the small ones, just extract and see it yourself...
[Samsung Galaxy Note 10+ Themes, Apps, and Mods] asafegous:
Again, that's the size of the original logo, not the pixel points at which the smaller booting_warning comes into it
[Samsung Galaxy Note 10+ Themes, Apps, and Mods] Dante63:
If I recall correctly, 200 x 400, that comes after the main bootload image...

In the s5e tab firmware I found the images in the abl.elf file which has an LZMA archive and in it there are a bunch of JPEGs that have the various warning messages and screens.

Yep, now extract the LinuxLoader.efi and run binwalk on it and you should see the images. Problem is that they are part of an actual UEFI application that is a PE64 binary. It would be much more difficult to replace them since they are probably not exposed on any file mount.

Deleted
[Samsung Galaxy Note 10+ Themes, Apps, and Mods] gcrutchr:
Thanks for the info.

There were 43 75 images in the file - see attached.

It really stupid how they are doing the images we see on our phones. The images we see are constructed in pieces, except for the download screen and the unlock bootloader screen. The samsung logo images are not in this file. Those are the ones I wanted to modify. That is why I think there is a hidden 'splash' partition.

Update: Re-extracted images using [MENTION=848727]weasal[/MENTION]'s suggestion. There are 75 images. I still think a single image is put together with image pieces.

It's a 37MB file.

SM-N9700 Boot Images
[Samsung Galaxy Note 10+ Themes, Apps, and Mods] weasal:
Your zip has 6 images that did not extract correctly and some that seem to be duplicates, did you use binwalk -D "jpeg:jpg" to extract the images?

The s5s linuxloader has 46 images including the ugly warning ones (see attached). I doubt they would split out 3 images just for fun.
[Samsung Galaxy Note 10+ Themes, Apps, and Mods] gcrutchr:
Ah! Okay. I wrote a 'C' program to extract the images. Should have used binwalk.

I will replace above imges.zip with new one.

Thanks for letting me know about the extract image command.

The big question is how to get any modified images back in the abl file so it can be flashed without bricking the phone?

If I extract the files from the LZWA file in abl.elf, I get 'Cryptest', 'LinuxLoader', and 'Odin'.

The images are in the LinuxLoader file. Does the order of items in the LinuxLoader file matter? If not, then I can just extract the images, modify them and replace them. Then repack the 3 files into an LZWA file, and replace it with the one in the abl.elf file. Yes?....Food for thought.
[Samsung Galaxy Note 10+ Themes, Apps, and Mods] EMSpilot:
Here is my abl.elf file. I have a SM-N9750. Can you check and see if it is the same as yours?

Cheers

[Samsung Galaxy Note 10+ Themes, Apps, and Mods] gcrutchr:
Hi Bill,

The contents are the same except for a few images.

Attached are all the images in your LinuxLoader file.

N9750 LinuxLoader Images
[Samsung Galaxy Note 10+ Themes, Apps, and Mods] EMSpilot:
I tried to extract the images myself with binwalk but couldn't get it to work. What command did you use?

Bill
[Samsung Galaxy Note 10+ Themes, Apps, and Mods] gcrutchr:
First, you need to extract the LZWA contents using imgtool (see attached) - 'imgtool abl.elf extract'

imgtool will create an 'extracted' folder. In the extracted folder, there will be 3 files. One of the files is LinuxLoader. Use binwalk to extract the images from this file: binwalk -D "jpeg:jpg" LinuxLoader
[Samsung Galaxy Note 10+ Themes, Apps, and Mods] EMSpilot:
Got it Thanks

Bill
[Samsung Galaxy Note 10+ Themes, Apps, and Mods] gcrutchr:
I am running all commands (apps) in Linux (Fedora).
[Samsung Galaxy Note 10+ Themes, Apps, and Mods] EMSpilot:
I have modified the 2 images and saved LinuxLoader. Now just need to know how to build abl.elf with Cryptest, LinuxLoader and Odin files extracted with imgtool.

Cheers
[Samsung Galaxy Note 10+ Themes, Apps, and Mods] gcrutchr:
Great news!

The 3 files are in an LZWA file in abl.elf. Can you send me your LinuxLoader file? I would like to do an analysis on your repack of the file.
[Samsung Galaxy Note 10+ Themes, Apps, and Mods] EMSpilot:
https://www.dropbox.com/s/kvc8nyj256vbvs4/LinuxLoader?dl=0

Here you go
[Samsung Galaxy Note 10+ Themes, Apps, and Mods] gcrutchr:
So, basically, you just blacked out the warning message.

How did you replace the images?
[Samsung Galaxy Note 10+ Themes, Apps, and Mods] EMSpilot:
Hex Editor

I used a hex editor to replace the images. You have to search the LinuxLoader with the hex editor to find the images. They all begin with ÿØÿà. Once you find them you put the image you want in the hex editor and copy it. Then replace it in LinuxLoader.

Here is the LinuxLoader that should work the best. https://www.dropbox.com/s/yqzapvrskuld6uj/LinuxLoader?dl=0. I replaced the images as follows in my attachment.

Now how do I build abl.elf
[Samsung Galaxy Note 10+ Themes, Apps, and Mods] gcrutchr:
Okay...found a way to do this whole process (except replacing images) a little more elegantly.

I found a tool - UEFITool - that will allow you to view, extract, replace and delete parts of the abl.elf file.

You should rename the abl.elf file to abl.rom.

After opening the abl.rom file, expand the sections until you get to the LinuxLoader.

Extract the LinuxLoader (Right mouse click on it. Select 'Extract as is...' ) as a .ffs file (LinuxLoader.ffs). Otherwise, the app will reload the file without any information displayed.

To actually extract the file, you need to click File/Save image file. Also, when re-inserting or replacing the LinuxLoader, you need to click File/Save image file. The File/Save image file is where all the work happens.

You can also just replace the LinuxLoader file. Highlight the LinuxLoader file. Right mouse click on it. Select 'Replace as is...'

This will replace the entire section for the LinuxLoader.
[Samsung Galaxy Note 10+ Themes, Apps, and Mods] gcrutchr:
I have rebuilt my abl.elf file with modified boot images (see images below).

Rename abl.elf to abl.rom.

I used UEFITool to extract the LinuxLoader as 'LinuxLoader.ffs'

Then used binwalk to extract the images from LinuxLoader.ffs (binwalk -D "jpeg:jpg" LinuxLoader.ffs)

I modified the images as shown below.

I used hex editor neo to overwrite the old images with the new images (new image files were smaller).

I used UEFITool to replace the LinuxLoader.ffs file.

Then I saved the abl.rom file.

I renamed the abl.rom file to abl.elf.

NOTE: the new image file cannot be bigger than the original image file. Just look at the difference between the image you are modifying and the adjacent image. Image names are locations in the LinuxLoader.ffs file.

Now I just need to figure out what to do if I flash the new abl.elf file, and it causes my phone to not boot. :eek:

N9750 Remove Boot Warning

Well gents. I finished the first test zip. Do not know if it works or will even boot. Hope to test soon.

Download the SM-N9750 link

Turn off your phone and then go into the download mode (vol up + vol down and connect USB)

Start Odin

Place the file "abl.elf.tar" in the BL section

Make sure auto-reboot is off in Odin if you want to reboot it yourself.

Once the flashing is complete, disconnect and exit the download mode.

Make sure you have a backup and are able to restore your phone before flashing as this has not been tested yet. Flash at your own risk.

Cheers

[Samsung Galaxy Note 10+ Themes, Apps, and Mods] gcrutchr:
Uh...you do realize the N9750 is the Note 10+ ?

EMS Pilot's abl file is for snapdragon phones, NOT exynos.
[Samsung Galaxy Note 10+ Themes, Apps, and Mods] gcrutchr:
So, I tried my version of the abl.elf file for the Note 10. I loaded it in ODIN 3.14. But, it failed. I think there is a CRC that needs to be regenerated. I think the problem is because of the data checksum. The data has changed, so the checksum has to change.
[Samsung Galaxy Note 10+ Themes, Apps, and Mods] EMSpilot:
Hmmm hopefully we can find a solution soon.

What we really need is a LinuxLoader editor of some sort.

Manually editing with a hex editor is 1) not very elegant, and 2) a little dangerous
[Samsung Galaxy Note 10+ Themes, Apps, and Mods] weasal:
I did some more digging and it seems this is a dead-end. The abl is the last stage of the bootloader itself and if it is not signed correctly then the previous stage (XBL) won't execute it. You can get a lot more details here: https://lineageos.org/engineering/Qualcomm-Firmware/. Even when you unlock the bootloader, the bootloder signatures are not ignored, the unlock configures the aboot to allow any ROM without checking signatures but not mess with the bootloader itself. And, as you can imagine, only Samsung has the keys to sign the bootloader and they won't be giving those away :)

You can see some work was done before (https://xdaforums.com/showpost.php?p=78473368&postcount=68) and they got to the same stage - if you manage to write a modified abl that the phone cannot verify you are going to brick your device. The One Plus seems to go into some special mode that allows you to somehow flash the original bootloader and recover but I don't know what the Samsungs do. The abl does have the recovery and download modes logic so if that doesn't boot then you get no recovery or download mode.
