Help i9505 won´t boot (recovery, bootloader, normal boot)

Help please,
Today i was using may phone as torch for 10 second then suddenly the screen went black but the led light on the back kept lightning.
after 10 more seconds the phone showed the i9505 splash screen at boot but went off after one second. i pulled out the battery for 1 minute (it was fully charged) and did put it back in. then again the bootscreen saying i9505 for a sec and the screen went black again. i tried entering the recovery but the same fail. recovery booting message and after 1 second phone went off. i tried entering download mode (vol down) and the download mode starts but after 1 second the phone is off. i tried it several times, with the charger but the phone wont charge while its off. can please some one help me?
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!

[STRANGE!] Screen won't turn on at all. Can get into Download mode. Screen stays off.

As the title explains, I can get into Download mode but screen wont turn on. I flashed Prism Barebone KK ROM and it's been like that since that. Luckily I know how to get to Download mode without the screen being on. I am flashing stock KK I grabbed from Sammobile right now but what if it doesn't work? Prism ROM does have that no bootanimation bug.
It's not a battery issue, I have 3 stock and one extended battery thats fully charged. So def not battery.

Okay so it flashed the stock ROM through Odin. DIdn't restart on it's own. I let it be for a while, it was connected to laptop, assuming my screen may have died I thought when it gets into OS I'll hear a beep on computer or Odin would detect it, or device manager. Nothing.
So I hit power while USB was connected, the boot logo came on (the Galaxy S4 words) and it stayed there for about 2 mins and turned off i think. Now the power button is unresponsive. I am gonna keep it plugged to the wall.

For reference, I downloaded "I9500XXUGNH2_I9500OJVFNG1_LYS.zip" from Sammobile. [Yes I have the i9500]
Edit/Update: So the phones screen goes on and off with boot logo WITHOUT BATTERY INSERTED! How strange is that........

Out of curiosity, when you insert a charged battery in your S4. Does the device immediately vibrate? If you were having issues with your power button, you would feel the device constantly vibrating because when Samsung S2 S3 S4 power buttons go out, they are usually stuck in the on position. It is extremely rare to have a power button stuck in off.

Power button doesn't seem to be an issue but it's unresponsive. No the phone doesn't vibrate on battery plug.

samsung galaxy s4 gt-i9505 can't access recovery and download mode bricked

Hi,
I have a problem regarding my unit. I am not very good in this stuff because I just started. I had someone root my phone for me and I learned how to flash custom ROMS. I had a custom ROM flashed and my phone was working fine. then I got bored so I flashed a different ROM but then I noticed some annoying features of the ROM so I switched back to last custom ROM I had ( the first custom ROM I flashed). One night my phone got fully drained so it turned-off. When I plugged the charger in the phone showed a symbol of a battery charging for about 3 seconds then it turned off. It did not turn on again even after I pressed the power button. I took out the battery and plugged it in the phone and then the phone automatically turned on and showed the name of the unit only (white text on black background: "SAMSUNG GALAXY S4") and on the top left of the screen appeared some text ("kernel is not seandroid enforcing" and below it is " set warranty bit: kernel"). I cannot access recovery and download mode( in a way) because when I plug in the battery and hold power + home button + volume up, in the top left corner of the screen, it states that it is in recovery mode but even before the TWRP could start, the phone would turn off immediately. Same goes for the Download mode. I can reach up to the part where I would choose whether to continue or not to download mode but even before I could make a choice, the phone would shutdown immediately. I have been using custom ROMS for almost a year now and never had a serious problem (aside from the part where my phone at times suddenly reboots for no reason at all) until that night where my phone ran out of battery power. Now i tried charging the battery using a clip charger because I was thinking that maybe the charging port of my phone is defective, but as it turns out, I didn't have any luck at all. I tried to plug in the battery again and the phone turned on automatically (without pressing the power button) but the problem remains the same. can anyone please help me regarding my phone problem? it would be very much appreciated.
Thank you

Your power button is stuck/faulty.
It's common problem on the s4. Try to wiggle it loose or replace it.

It's the power button.
Your device will not turn on because the power button is stuck in the pressed position.
Replace or try to loosen it.

Boot Logo Repeating

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.
