How To Guide Guide to remove bootloader warnings

[gav83collins]

Here is a detailed guide on how to remove the bootloader warnings that appear at boot after oem unlocking your bootloader

please be sure to go over to here and give juda iskariotsky a like

if you want to remove them your self you will need
(only tested on Exynos)

Modded 7zip = Gdrive - Mega - Dropbox
Odin 3.14.1.3b = Gdrive - Mega - Dropbox
your firmware extracted


to just remove them without doing it your self

flash the up_param.tar file in odin under the BL tab
get it here = Gdrive - Mega - Dropbox


to remove them yourself you will need to follow these steps
(there is a video below too)

1st - download and install 7zip standard , and download and unzip odin
2nd - navigate to the extracted firmware and right click on "BL_S908BXXS2AVDB_S908BXXS2AVDB_MQB51326408_REV01_user_low_ship_MULTI_CERT.tar.md5" {your firmware may be different}

3rd - select open archive with 7zip standard, once its open drag "up_param.bin.lz4" into the firmware folder window and drop

4th - right click "up_param.bin.lz4" and select "extract to "up_param.bin/"" using 7zip standard

5th - navigate into "up_param.bin" folder and right click "up_param.bin" and select open archive using 7zip standard
6th - select the two files "svb_orange.jpg" and "booting_warning.jpg" keeping your finger pressed on "ctrl"

7th - press the "red x" delete icon in the top bar to delete them

8th - close that window, and in windows explorer right click the "up_param.bin" inside the "up_param.bin" folder and select add to archive using 7zip standard

9th - in the archive format tab select "tar" and click ok, that file is now ready to be flashed in odin



10th - open odin, clicking "ok" to dismiss the warning, the press "bl" and navigate to "up_param.tar" inside the "up_param.bin" folder

done......

Do you recommend to keep the created up_param.tar to be used after each update?

 

[gav83collins]

i would like to say yes, but its possible samsung changes something and flashing the up_param conflicts with a change they make and causes an error, its unlikely, but never say never

Well detailed Guide, Thanks!

Wish there was something for Snapdragon users.

Nice

Does it work in snapdragon? Is it risky to test? Don't want to reflash and go through all the hassle of getting the phone exactly as it is now, since we don't have TWRP backups yet...

i wouldnt flash the file, but if you follow the guide, you can look in your directories for the same/similar files, its untested on sd variant

I have tried on snapdragon but there aren't such files there.

Its great. Thank you for your support.

Exynos has the param bin file, Snapdragon possibly has it somewhere else.
Firmware code is S908E.. Give it a try, and its lovely if you succeed !

Cheers!

ive had a prelimenary look around but, the file types are a lot different to mine, so im gonna have to get more software to be able to open and explore further

Yes sure. You are the person that can make it possible. Good luck.

I was going to post my print, but mrjoy posted before. Digging around, it seems that this is not possible for snapdragons, at least for previous devices. It seems that the boot file is mounted during the boot and images are loaded, there is no way to extract and replace the images there without Samsung's signature.
I'm just writting what I found in other threads, though.

If you want to dig, it seems it is part of abl.elf file. See if you can get this to work.

Maybe if we could do that by another mean?

 

[mrjoy]

Any updates for S908E?

 

[JazonX]

Any updates for S908E?

I wish for the same too. Guess no luck so far

 

[BrimoFan123]

I have followed your steps but it failed with my S22 Ultra Exynos :-(

Could it be because of "Universal Samsung PARAM Changer" Magisk's module?
Or "WETAmod" Magisk's module?

then there is no way to remove the bootloader warning in the snap version
