Method 1: Fix Missing OEM Unlock on Samsung using Day/Date Tweak
I have just checked the only way I can get oem unlocking is by downgrading to one ui 7 which somewhat isnt a problem since my tab a9+ has the same binary number as a version of one ui 7
i managed to downgrade to oneui 7, unlock the bootloader tomorrow ill install /e/ os using Colors recovery
also where do i get the recovery.img from i cant find it?
Read before making any action!
look like Heimdall is missing in your collection..
custom android builds - Browse /tools/heimdall at SourceForge.net
waht does heimdall do?
flashing .IMG files to target partition.
it is THE Open Sources Flash-Tool for Samsung devices since 2010
how do i use it after installing it?
as usualā¦

most used command are
heimdall flash --RECOVERY recovery.img --no-reboot
heimdall flash --VBMETA vbmeta.img --RECOVERY recovery.img --no-reboot
heimdall -h

[--usb-log-level <none/error/warning/debug>]
Description: Attempts to get rid off the "connect phone to PC" screen.

[HOWTO] (Needs expert review) Flash Galaxy s9+ to Stock Android 10 using heimdall-gui
the file im suppose to flash is called fastbootd-recovery.tar.md5
for that Odin4 will be easier,
about flashing custom recovery, be aware that Odin4 linux donāt have any no-reboot option. (unlike Heimdall or Odin3 windows)
i extracted it and theres a recovery.img in it can i use that?
EDIT: Why would i need a no reboot option?
as usualā¦
it can help you to be able to reboot into recovery immediately after installing the custom recovery. If you donāt, the custom recovery will be overwritten by the previous stock recovery on boot. and you will have to retry the flash.
ohhh never knew it would just overwrite it i tried using odin on linux and it keeps outputing āno devices foundā even though my tablet is plugged into my laptop (Im using a usb c to c cable that came with my phone in the box) and heimdall keeps outputing
./heimdall-frontend: error while loading shared libraries: libQt6Widgets.so.6: cannot open shared object file: No such file or directory
look like your Linux distribution need the libqt6widgets6t64 package (part of qt6-gui)
exemple for debian based (ubuntu) :
sudo apt install libqt6widgets6t64
anyway, heimdall-frontend is not very usefull
but heimdall is
