Help Phone keeps restarting at recovery screen

[webking]

Hi guys,

I have an issue with my phone:
Yesterday, tried to restore factory settings, since the phone was quite slow.
A second or so after I confirmed the reset, the phone turned off and wouldn't start.
I took out the battery and it was swollen.
I bought a new battery today, inserted and stated the phone.
What happens now, is that the phone boots, Samsung logo appears, then the TWRP logo appears, from this point, the phone stuck at this logo screen,
and flashes every few seconds (see here: https://db.tt/GxGyNPg4 ).
I tried to leave the phone for about 20mins without battery at all, removed SD cards, removed SIM cards, no use.
Trying to boot to recovery or download mode gives the same result.
Tried today with an original battery of a friend's Galaxy S4 , same result.

Does anyone have an idea what I can do?

Thanks in advance for you help

A swollen battery is evidence of overheating.
Your phone may be fried.
Also, that battery is damaged, unstable, and could burst int flames at any time.
It should be slowly discharged completely and properly recycled.
