[Q] I9500 stuck in reboot loop, can't even do a hard reset

Hi guys,
i was just using my I9500, and out of nowhere it just turned off and keeps on turning off the screen then lighting up to the galaxy logo then off again
tried to hard reset the phone (vol up, home and power) and to enter download mode (it does enter download mode for just a sec then restarts again.
when i connect the charger it keeps on displaying the empty battery pic and tries to stuck again and repeat (starting from the empty battery image), although its at least 30% charged
help guys .. thanks in advance

Have you tried removing battery?
Sent from my GT-I9505 using XDA Free mobile app

Oh my this problem seems to be very popular. Anyway, it's happened to me before. Leave the battery out for like a day or two and then try it again.

@myawan
Yea, but just as soon as I insert it again it starts on its own and keeps doing this loop
 @MacSual
a day or two ! I already left it for a few hours it didn't change a thing !

You have a faulty power button, a damaged battery or some other hardware damage. My guess would be number 1 or 2.

I was guessing number 1 too, but have no experience with the hardware what so ever :S, I guess I'm taking it to a shop tonight I guess :S

i use latest cm11 kt all in one recovery latest bootloader and googy max kernel. and i cant use odin because the bootloader(download mode) is only present for 1 second.:crying:

Take out your battery and check serial number if it starts with BD it's a bad battery.
If it's BD you now need to get in touch with Samsung official and you are eligible for free replacement.

some say the power button is stuck while it was pressed
some say the battery is defected

I fixed it my self the power button wasnt defect. i dont even know what it was i just tapped hard with my nail around the back camera and it booted succesfully after i pressed the power button. can anybody imagine what it was

OMG I had the exact same issue! I was searching for my soccer ball and used the torch for around 30sec and suddenly the phone went blank. I thought it was a dead battery but it turnt out it wasnt! I cant fix it now:crying: Using Dans GPE5 ROM with googy kernel. I know neither of them are to blame, but seeing that the torch could be a suspect
EDIT: LOLOL I tapped the phone just like you did and it was fixed! What a mystery!

Did you used Original Samsung charger? if not that might be the problem.
Your phone is probably damaged internally since you said it overheated.
Go to your nearest samsung store or carrier and ask there. hope your warranty isnt voided yet.
Good luck.

i borrow charger and im not sure if its original or not. im not sure if this still has warranty.
what might be the problem? how much will i pay if they fix my phone?

depends on samsung maybe its for free.
The charger isnt compatible with your device and maybe it overcharged and overheated the device.

Is my phone done for? (Cant bot/charge/enter download mode/no response)

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.

if you did factory reset and problem is still there, there is probably hardware fault, go to repair shop

hi
i have this issue since this morning. maybe 3 or 4 freezes.
do you use edge screen features? i have enabled them yesterday and today have this problem. i think that could be a reason.
to fast restart your phone you have to hold down + home + power buttons and then click down button for reset.

No Im not using the edge screen and this method not work to restart the pbone even if I hold it to hours it can be restarted only when battery drained and the blue light stops linking which mean battery drained then I pluged it to charger then I can press power button and start it.

Wait for the battery to get fully discharged and then again charge it. It will start again. I am facing the same problem since some days and didnt get any solution for it. Does your phone heat up too?
