[HELP!] SGY GT-S5360 Fails to start

I'm really sorry if I asked this question again if it may have been asked earlier, but i really need to get answers ASAP because I could not use the internet all of the time.
Days after I rooted my SGY GT-S5360, it would no longer start and it would not charge either(both by charger method and PC method of charging) . I also tried going to Recovery Mode but then again it does not. So I tried charging my battery using a universal charger for a short while. After doing so, I placed again my battery to my device and tried turning it on. It would turn on but only until the "Samsung Galaxy Young GT-S5360" logo and then it would turn off again. I tried taking the battery out and then putting it in again, but the same scenario happens.
I am sure that I am not on a BOOTLOOP issue because it shows no symptoms of it. And I would not want to believe that I am Hard Bricked because my device still boots only until the "Samsung Galaxy Young GT-S5360" logo. PLEASE HELP ME WITH THIS PROBLEM
By the way, I have not flashed any ROMs or Tweaks or Updates on my device and I am still on my Stock ROM.]
Please do Help me with my problem

[Q] Bootloop

Hi guys, ive seen alot of boot looping posts, but this one is a normal GT-9500. I do have apps, all from the appstore, and my phone is under 1 year old. It has been working fine recently, and out of nowhere today, while using whatsapp, it began boot looping. So i tried using recovery mode with no luck. The icon appeared, only to quickly disappear as the bootlooping continued, and the same with Downloading mode. I have no idea where to go from here, and i really Hope that someone can help me restore my phone to working order.. Please and thanks​

I cant enter into recovery mode to do that, and i cant go into download mode. The phone just keeps restarting.. No matter what i do. Could it be the power button stuck? as soon as i put in the battery, the phone automatically tries to start itself.

[Q] i9500 rebooting into s4 logo even download mode is rebooting

my galaxy s4 is always boot looping into Samsung galaxy s4 screen. only the download mode screen appears but it reboots again after 5 seconds and keeps on rebooting . any help ?
Do you run with stock or custom recovery? Have you tried to (re-)flash a custom recovery (CWM highly recommended)?

Hm, if I understand you correctly, you can boot into download mode but it just lasts a couple of seconds before it reboots on its own, right? You cannot boot into recovery as the screen simply stays black. Can you boot successfully into /system or does it bootloop as well?
Sounds like a hardbrick to me, the only thing I can think of before sending your phone in for repair is to pull out the battery for 1 hour or so, reinsert it and boot directly into download mode and see if it stays there. If it does, flash a custom recovery using Odin and check whether you can boot into it afterwards.

Im also having the same problem as of this last night.
cannot boot into recovery.
boots to download mode first screen but when I attempt to press volume up to accept, it reboots.
as soon as i put the battery in it cycles through the samsung logo.
tried removing memory card but didnt help.
tried keeping battery out overnight, nothing.
last thing i changed was flashing --> http://forum.xda-developers.com/showthread.php?t=2201860. did this about 2 days ago.

I think it has nothing to do with it
I'm, I was actually, on stock everything, rom, kernel and recovery
30 68336826
OK so I left my phone without a battery in it for the afternoon, just got back home and gave it a try.
It booted. No idea why or what actually went wrong.
Lets hope it doesn't happen again!
OK, So the point that the phone just start booting just the moment the battery is inserted got me thinking
IS IT THE POWER SWITCH?
and indeed it's, the power switch is stuck on, although I can feel the click when I push, still, seems like something is wrong with it
so I tried to suck it out, hit the phone softly few times while the power switch is facing the ground
inserted the battery, aaaand, it didn't start booting, pressed the power softly, and horaaaaay, it's working
Had the same issue and indeed I knocked the power button several times and it worked very well. Thank you! You saved my day

I have similar problem... and identified its power button.
How i identified is as phone switched on i hold menu button and volume down button together and
it booted in download mode, for download mode you have to keep pressing power button, volume
down button and menu button but it went without pressing power button.. so i assume that its power
button.
Try it... hope will identify your problem
same Problem
Hello!
I have the same problem, and disassemble the cell and saw that the button will operate properly .
Someone has managed to get out of this problem?
thanks a lot... i was facing same problem... i hit ma phn near power switch...again n again... it worked... love u xda
whoa, I just got this problem recently, because some of bezel around my phone has cracked, then I try to glue it roughly.
at the other hand, I tried to install new kernel. I tought that kernel make my phone bricked. then I found this thread. so I open my case. and found my glue sticked to the power button, remove it and. voilaaaa~
thank you XDA. you never cease to amaze me. lol

[Q] S4 in bootloop after installing Lollipop over OTA

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

1- can you go to download mode?
2- can you go to recovery?
3- if you put the battery back, it starts by it self or not?

Hi RubbaBand,
1- No, I am unable to go into download mode.
2- No
3- When I keep the battery back, phone starts by itself. Samsung logo pops-up. Then it restarts again.

Hi Nikhil,
Can you try to get into recovery mode? You need to understand a few commands of ADB also. Don't worry. Your phone will be working again. Remove the battery for a few seconds and put it back. Don't start the phone. First hold the volume up button and then at the same time hold the volume down button. Keep pressed both the buttons and then press the ON button ( All three buttons at the same time ). After your device vibrates a little and sows the YU Logo, let go of all the buttons......you should get into the bootloader menu. Tell me if you can do that. Will explain the steps further after you reply.
Yes I can enter into the recovery mode, but when I try to enter into the bootloader it shows fastboot mode for a sec and then all black screen. I want to tell you that my phone is not rooted and neither i unlocked the bootloader nor installed twrp or cmw!! But still it is bricked without any reason. Is there any solution to recover my data??

Hello..watching my switched off yureka for over 3 days now. Tried flashing cwm recovery finding nothing else to do. Till that time I hadn't tried switching the phone on while plugged in. Don't know if the cwm recovery thing worked or not, but from then on I am unable to reach the recovery (vol up+vol down+power).
But then suddenly in the plugged in state my phone comes alive and boots completely!!!:cyclops::victory:. And then I get to know that while charging, the gandu phone is completing its boot process. But after a few minutes its blacking out and starting its on and off routine again. (minutes varying from 1 to 45 , not sure depending on what, because now I am running hotspot and LTE on the phone to write this on the laptop..and yet it is awake for more than 45 minutes now got a vibe that if the screen is turned off the phone will not shut down. ) ... guys please help. how to make it work without the usb pushed at its back...?
Edited a day later: went to the service centre.. They simply said the battery needs to be replaced. Yes it is all good now. Relieved.

yes it did stuck once or twice at the userdata erasing stage when I was putting up the new ROM but after some attempts,it never got stuck at any stage but even after successful installation, the problem existed...Now I have given my phone for repair and the store person said that there is some power issue in the board...its not an software isssue.
