Dont know if any one is facing the same problem.
Installed Lollipop in my S4 over the air, 2 weeks ago.
A week back, my phone entered into BootLoop mode. Phone gets re-started. I can see Samsung logo and it gets restarted again. I tried removing the battery and kept it back. Started working fine then.
Since today after noon, my S4 is in complete boot loop. Tried removing the battery and kept it back. Yet it is in bootloop.
Unable to enter into Developer options also. Please help
I hit the Power Button against a Flat Surface. It Vibrates and shows the Samsung Logo. But then it turns off.
Is the battery empty maybe?
My guess is that your power button is faulty. Either try to wiggle it lose or replace it. It's really cheap
If it reboots in download mode and/or your recovery then it's your power button.

By the coincidence, is your batt serial no beginning with BD? If so, look on the battery. Is it swollen a bit? If so - call samsung, they will replace battery free of charge.
If not, try to connect phone to charger, insert battery, go to recovery and make full wipe.

it might be a power button issue
ok, this may be tricky.
while keeping volume down and home - slice battery in. If phone would boot in download mode (even just for a while) - then it will be power button issue.
it boots up on download mode for seconds and then powered off again....
Im digging up this post because this is the same problem i had.
I ended up removing the power button all together, carefully popped it off the motherboard. The phone no longer boots for a couple secs and powers off again so i think the power button was the issue. Now i have the problem of powering on the phone. I tried booting into download mode (to have the reboot option) by holding volume down+home while plugging it in but nothing happens, all i get is the battery charging icon. Ive been into download mode before i removed the button, but like the OP, it would only be a second or 2 before rebooting. Am i doing the correct procedure for download mode? Perhaps my timing is off? Any suggestions?
At least i do get the battery charge and it stays until i unplug the phone, no more boot loop!

Ok so i managed to get the phone to power up without going into download mode using this method i found on youtube. No boot loop and fully powered up now, the only thing is that im stuck on the lock screen. My friend cant remember his pin so i cant get in, the only option left now is to boot into recovery and do a factory reset yes? Well, how can i do that without a power button? Any suggestions?
I was running this custom rom beautifully fine for over a year now since I got my phone.
Recently I've had so many problems. My phone just randomly shutdowns down and it's very hard to get it to boot up again. If i hold down the power nothing happens or I just get 1 vibration. Taking the battery in and out doesn't do anything. I left it for 5 minutes out and put battery back in it just vibrates a little (samsung logo apepars for a second) and nothing happens, even when I hold power button. Can't get into download mode either.
I tried 2 different batteries too.
Really not sure what to do. I tried a factory reset a whilst back and i thought everything was okay but now it just won't even boot up.
Whenevr it does decide to turn on it just dies after a random period of time.

emm.. your description is confusing a bit... does your phone boots, or not?
If not, call the Samsung service centre (if I'm right, one is in Milton Keynes even, if not, there is another one in Derby).
If it does: try factory wipe and pure stock reflash.
I've looked online, especially on here, for solutions to my problem but they all seem to assume that I can access fastboot. Here is my specific problem:
I was using my phone and suddenly the screen went black. It rebooted once into the OS but immediately restarted and has been stuck in bootloop for 4.5hrs thus far. I have tried to wipe cache, enter fastboot, power down the phone but nothing worked and it kept looping. Even when I powered off. It's like the power button signal is malfunctioning because it doesn't always reboot at the same exact point in the boot cycle.
My phone is stock, no custom anything, and is encrypted. My only thought right now is to let the battery drain fully and try to boot again after that. I have not tried to enter fastboot while connected to a PC, but I have tried to do it just on the phone.
I have not been home yet so I do not have access to a PC I can actually do things with at the moment. Any help is much appreciated. Thanks!
EDIT: I am home now. Going on 6hrs of looping and nothing has changed.
EDIT 2: The battery was drained. It starts to charge but instantly tries to enter the boot loop again so the battery never gets enough charge to do anything; thus, I can do nothing to save the phone, I don't think.
If its some malfunction with power button, try to abuse the button gently. I used to do that with my Nexus 5 when its power button gets stuck inside causing bootloops.

The button itself is fine, it works as it should and is not pressed down; however, there might be some sort of internal problem causing the phone to think that it's being pressed.
So few days ago my phone suddenly turned off and kept rebotting itself (It would reach the samsung galaxy logo and then turn off). I thought it was a battery issue so I removed it for 30mins and tried again, worked fine for an hour then problem started again. I left it over night to charge in the wall socket incase.
Same issue next morning and no solution.
I replaced the battery with a friends and the same issue happened on my phone (i used my battery on his and it works fine on his) so I removed the issue of battery itself.
That evening the phone then just stopped responding at all. It would not respond to pressing the power button (no load, no vibration).
Tried entering download mode using vol down + home + power. Nothing. (So cant use Odin)
Tried entering recovery mode using vol up + power. Nothing
Tried hard reset using vol up + power + home. Nothing.
(All the steps I used a fully charged battery from another s4 phone and removed/re-entered before trying again)
So I check online and notice some people having issues with power button, but even if that is the case - wouldn't my phone still charge? I dont even get the battery chargning icon on the screen when plugged in either PC or wall socket.
I opened it up and changed the motherboard with another samsung s4 and my original problem mobo still does not load on the new s4. (My new mobo worked on the old device though).
The ONLY response I got was when I used my original mobo on new s4 device and plugged it into PC, it popped connect and then disconnect sound and thats it (doesnt recognize usb port).
What are my options apart from getting another motherboard or going to a shop for a JTAG repair? I was contemplating just removing the power button and seeing if that helps in getting a charge response lol
Well your power button is broken for sure. Replace it and then test it.

Wouldn't the phone still recognize charging even if the power button is faulty?

It always takes a few seconds before it starts to charge. So maybe the device reboots before reaching the charging phase. I'm guessing though. But since your problems started with power button issues it would be the logic place to start.
The part only costs a few dollars.
Well I'm exactly in the same situation as you, since this morning on a i9505 running JFLTPE-GPE 5.0 ROM. The screen appears for 1 second or 2 (Samsung logo) then it powers off . I need to remove the battery to try something else.
Same behaviour, even for recovery mode, so Odin is not an option.
I thought that changing some kernel settings have caused that, but as I just put them back to default values, it should not happen.
I didn't have some power button issues, it was just powered off at my wake up this morning. In your case, does your phone vibrate and power up instantly when you put the battery ? That's the case for me, but it should not be the normal.
My problem is actually solved : indeed, it was the power button. I removed all the screws and played a little with this power button (air dust, etc...), enough to make it start correctly !
I managed to do some backups, and now I hope that it won't break again.

Yeah, that happened before (automatically powering up, vibrating, going to samsung logo and then shutting down and doing it again until I removed battery - putting the battery back in with start it up without pressing the power button).
When it was in that phase, the one thing that did work was doing a soft reset (home+power+down vol, and then holding just power) - however that only worked for like an hour before it went back to the restart phase.
However now it doesn't respond to anything at all. (Any kind of response I got was when I put that mobo in another s4 and plugged in usb, which just gave a connected/disconnect sound on w7, no life on the phone itself).
Be very careful as to what you do, I suggest you do NOT leave the battery on it and charge it (which was the last thing I did before it went unresponsive) - my guess is phone went haywire trying to turn on/off continously.
I have a galaxy s4 (i9500) and got it in used condition, a year ago. Never suspected a single problem in it.
Today I powered off my mobile for charging then after 25 minutes I took it off. I held the power button then I saw my boot logo(Where there is written Samsung Galaxy S4 GT-i9500). That logo kept showing as usual for 2 seconds and screen went black and again that logo appeared for 2 seconds and screen gone black and again it appeared, so, I'm stuck in kinda loop not a bootlooop exactly(maybe because bootloop refers to being stuck on boot screen while in my case its boot logo). I then removed the battery and inserted it back after an hour and as soon as I inserted it back the mobile itself turned on as if I held power button but this time again I was stuck in that loop. Moreover when I tried going into download mode, I didn't even need to hold the power button along with the volume down and home, it itself proceeded to confirmation screen of odin mode. And after that confirmation screen appeared saying that whether I really want to boot into download mode, disappeared itself after like 3 or 4 seconds even though I didn't press any key. And in case I press vol up key confirming to boot to download mode, then it again takes me to that loop. I'm too much confused . I can't even flash the firmware as it won;t boot to download mode neither am I able to boot into recovery.
Now do u really think the problem might be the power button(Which is maybe stuck in the state of pressed).
Or else it can be the battery coz my battery is also just average not too good?
I also inserted the command( in build.prop file) for enabling nav. bar and the code was correct but I never rebooted after inserting that. this was the first time I rebooted after that.
SOrry for some bad English.
Do you have something like this? I'm now having problem with getting my phone back to work...

From what you say it seams like power button problem, try to start the phone and connect it to the charger. When it start take out the battery, it will be powered by charger and you will eliminate battery problem.
