Samsung Galaxy S4 — How to phyiscally Hard Reset a Galaxy S4?

Hey guys,

My phone is stuck in a boot loop... can't turn it on and I can't access the recovery mode. I went to a repair shop, and they said if they hard reset it, it should fix the problem... and I was like, well how are you gonna do that if the phone isn't switching on, and you can't access recovery mode? They said that there is a way they could do it physically or something, without needing actual software access, but that it's gonna cost me 45 Euros!

Now my question is, how could I do that my self and save 45 Euros... is it possible?

can you access the download mode ?
Vol down + power key + home button

if you can't buy a USB JIg ( 4-5 eur) they force a Samsung device into download mode so you can flash firmware over Odin and restore it to working order.

Thanks for the reply. I can access Download mode, however, as soon as I press Volume up or Down, the phone just simply restarts and the same problem repeats.

Did you try taking the battery out for a few seconds before doing it again?

Have you tried emergency firmware recovery from kies ?

Kies was unable to detect the phone, only Odin... I flashed the stock ROM on there, and apparently that was successful. I went to a phone repair ship, and they didn't really check the phone, but I told them everything I did, and they said it might be a boot loader problem, and they said, if that was the case, I might as well throw it in the trash... nothing to be done.

Haha of course! That was the first thing I did... I even left the battery out over night once... I also drained the battery all the way to 0, and then tried to start the phone all over again..
