Try to boot in Safe Mode by pressing Vol Down button AFTER the "Samsung Galaxy S4 GT-I9500" boot logo. If that problem persist, try to factory reset your phone. Most likely it is a hardware problem, the display has probably worn out

[Q] S4 stuck on boot, How to install Jellybean

My samsung galaxy s4 (GT-I9500) does not go past the samsong logo with the i9500 and the samsong name.
I put a new simcard in my phone, and after my phone started it asked me to update the phone to a new release. I obviusly clicked OK.
my phone started updating, just like it normally updates, but this time the screen goes black in the middle of the update. I turn on my phone, and it starts installing, then suddenly it turns off again.
when i turn it on it loads the first boot logo, then i get a black screen like the phone was never on.
i tried everything:
- battery of and on
- wipe data/factory reset (from - volume up, home button, and power button)
- wipe cache partition
- and apply update from cache has an empty recovery folder.
- i tried to boot in safe mode.
and nothing worked
I want to reinstall jellybean(or any os that works) on the phone, but since i can go to settings and allow usb debbuging, my computer does not recognize it even when it is on doenloading mode (volume down, home, and power button) from my ubuntu turmenal.
I am willing to root my phone or anything to get it working without paying money.
How do i fix this? please help!

Why do you even give him this advice? It will do absolutly nothing that will help him.
If his device even reboots in download mode, then doing a factory reset will be completely useless.

my S4 gt-i9515 is stuck on boot loop

my galaxy s4 gt-i9515 is stuck on boot loop. This is despite numerous efforts of flashing stock lollipop 5.0 rom into it and when it eventually boots up the phone heats up and the screen turns bright white. I've even checked on the power key and its okay.
Potential hardware issue. Meaning, get a new phone or an S4 with a broken screen and replace the motherboard.
Can you access download mode or recovery?
Clearing Cache
Remove the battery then place it in and press the volume up home and power button at the same time hope it helps:

When it goes to the samsung screen, quickly hold either the top or bottom volume button and the home button until the screens goes into a blue screen that says recovery mode, and then flash stock firmware. If you have twrp installed, try wipe dalvik, cache and do a dirty wipe of the current rom you have. hmu if you need anymore help.
I have the same problem but it did not fix.
Also when i tried to charge it, the charge icon appeared, dissapeared and shut down with the same timing that logo Samsung appear and dissapear when i try to turn on. But after different tries the charge icon dissapeared replacing it with the Samsung logo, keeping the problem.

You can't flash stock firmware in recovery
Can you recover it with smart switch to stock? If not do it via odin
