iPhone 4S stuck on Apple logo with loading bar, DFU non reacting

Hello,
my iPhone 4S after update stuck on Apple logo with loading bar.After a while, the phone restarts and the whole procedure is repeated. iTunes phone will not load. When I try to put the phone into DFU mode, the phone displays only the message about connecting to iTunes, and then the phone restarts. Today I discovered that the battery is faulty for this reason I tried the functional battery. With functional battery the phone stuck on the Apple logo and continued with no restart. I tried put the phone into DFU mode the phone displays again only the message about connecting to iTunes, and then the phone restarts. This problem start after updating my iPhone. I would like to ask if there is someone with the experience with it and would consult this problem with me. Unfortunately I did not have a functional battery enough time, I could leave the process to let the Apple logo for more than 15 minutes, because I had borrowed that battery.

For better image of my problem I uploaded a video on YT: [redacted] (In video is a phone with a dead battery, because I had tthe borrowed functional battery return and I did not have enough time to tried it with functional battery.

Thanks for your responses.

It is possible that your device has become defective, and therefore, I recommend you make a genius bar appointment with the nearest Apple Store to have them diagnose and attempt to fix the problem for you. Thanks.
