Why did you choose to leave the message of the "svb_orange"? We all know bootloader is unlocked, message is useless and undesirable since boot continues anyway after a few secs (no need to press power).

Anyway, that's what I've done on mine, replaced it with a nice screen, acting as second (boot)logo.

That message doesn't really bother me so I just kept it.
We could have used full screen, but it would have looked like this cause the image is still there, just blacked out.

Yes, of course, I forgot that it just gets overlayed on top of logo image, because my logo is mainly black and booting_warning is black too, it's there but invisible.

A quick how-to using Windows:

You know the drill, if you manage to damage your device when doing this, it's your own fault!

1. Download the firmware for your device from your preferred server (samfrew updato , select region, version), alternatively jump to the end for faster approach, but you may need knowledge described in next steps anyway

2. Have installed 7zs

3. Right-click the firmware file > 7Zip ZS > Open Archive > then double-click (dc) file that starts "BL.." > again dc param.bin.lz4 > again dc param.bin > extract all files

4. Files to customize are:
booting_warning.jpg
logo.jpg
svb_orange.jpg

Use favorite image editor (Paint works!)
Make sure you keep the default resolution and do not create much bigger files than the originals, a little bit smaller or bigger it's okay, but not too much.

5. Again using 7zs create a tar archive format with the files you edited and the rest you have extracted before, name the archive param.bin (literal, NOT param.bin.tar)
(7Zip ZS > Add to Archive > Archive Format: tar > Archive (name): param.bin)

6. And then again, create another tar file with the param.bin in it (archive name may be anything)

7. Using Odin, load the tar file you created on the previous step to the AP slot, connect the phone in download mode and flash

Alternatively, to save data and time download bootlogo mod from first post, just extract files, edit and repack again using similar manner as described above
(in the end you should have a file with tar extension instead of MD5 because archive does not have MD5 checksum attached, so Odin will not check data integrity)

Thank you Bro !!

It works like a charm.
Very happy with this mod

Fred.

i know how to make it work with Odin but i was wondering if with the stock recovery it's possible to sign an update.zip containing this mod....
i tried an old zip signer with no luck ( probably it was with an old Android version).

This blacked out so that it won't show on the black logo background.

Unzip Attachment 4790675 and put the tar.md5 in AP slot in Odin. Connect phone in download mode and start flash.

Hello. I installed this patch last july (release without leaves):
- is that version (no-leaves) still available / usable with ASJ firmware ?
- in general, how could I revert mod to the original ? Flashing full stock firmware doesn't affect bootloader area, it seems

I don't have TWRP so I'm talking about Odin releases
Thanks a lot for your work

Twrp with an update.zip style
Or flash with Odin
Perhaps files and directories are différents...
