Ok so first make sure that you have JavaFX installed. For that just type sudo apt install openjfx in the terminal.(This might be optional for you, if you get an error containing JavaFX thats the command to fix it)
Since JOdin doesn't quite work when launched via the .jar file the only way to get it to run is to use the binary. Thats the file in the very first folder just called "JOdin3CASUAL".
But since we are not running the jar directly we cant add -Xmx2g as a launch option. In order to get the bigger heap size type export _JAVA_OPTIONS=-Xmx2g in the terminal. You have to run this everytime you close the terminal window. In order to keep this setting permanently add this line to the .profile file in your home directory.
After that go into the folder with app, runtime and JOdin3CASUAL and type: sudo ./JOdin3CASUAL
Hope this works for you.
I took all the steps you wrote down for me and I got JOdin working, finally..
But there goes something wrong still.
Because ... uploading the stock ROM (1,5GB) should take a while, is not done in just a few minutes.
Uploading all the files should take at least 10 minutes to complete.
Yet, in the end, it does say reset in green though.
And I'm quite sure that something is wrong, because I didn't see the blue status bar on the Samsung tablet during the upload process.
Uploading the extracted files seperately in Heimdall, 10 pieces out of the stock ROM, will take 10 - 15 minutes to complete and the largest of them all is the 'system.img' file which is 1,2 or 1,5GB in size.
With Heimdall I do see the status bar in both the program while uploading and in blue the same status bar on the Samsung tablet.
On the end of the day, I still have a rooted and faulty Android system running on that Samsung tablet.
Somehow the clean factory default is not loaded when the Samsung device reboot after all uploads with Heimdall.
Although the software uploaded is Android 4.4.2 for Tab3 7.0 8GB WiFi, with all the correct changes, date of build and country code.
Is there a final method to clean out the current faulty content of the Samsung Tab3 device?
