Hi, I have a Samsung S4 (i9500 International) on Android 5.0.1
I cannot get any logs, apologies.
Stuck in Boot loop, CAN'T even access Recovery. If there is another thread for this please kindly let me know, thanks.
I had CM12.1 on for a month (working perfectly) until my device started rebooting all the time.
I then wiped all cache and deleted all data, moved to Aurora N4/S6 Port Rom for 2 days, but same thing.
I have: Taken out the battery, sim card, memory card, drained all power, deleted apps (All together, combination of some, and separately).
I cannot boot into Recovery (TWRP) as it; reboots either on Recovery Loading screen, or while actually in Recovery.
It will sometimes completely reboot and I can use my device for different variants of time.
The battery has gotten really hot, when this started, but not a common occurrence.
Whenever the battery is inserted, and device is not charging, it will start the boot loop.
While the device is off & charging, the charging screen will flash.
What are the possible causes, AND / OR fixes?
Thanks in advance.
Could be something related to your power button.
Your power button is stuck and needs to be fixed by releasing or replacing it, happened to me once and solved by hitting the phone on the ground xD
But you can access the button if you are a handy guy.

Hi all, i installed the CM11 on my gf's Galaxy s3 (i9300 international version), the problem is that sometimes it randomly reboots and get stuck in an unusual bootloop. It reaches the bootsplash logo and it keeps rebooting, the only solution to get it back to work is to remove the battery for at least 30 seconds and try to turn it on, sometimes it works.
When the bootloop happens i'm not able to enter the recovery mode, because it just turns on and it keeps rebooting, same thing with download mode.
So, i'm new here, but i read about a common issue which is the sudden death syndrome and half-sds, it might be that? I checked and it has the insane chip.
Any advice/idea? It would be better to flash a stock ROM to be safe?
I would backup the whole device, recover initial firmware using kies emergency recovery mode and then start over again.
Had a similar problem but even worse: same bootloop, but no dice on recovery :\
Was unable to reflash or restore old firmware using Odin, Kies was the only thing that worked for me.

Do the reboots occure few seconds after pressing the power button?
I have exactly the same problem and I figured out that my power button is kinda stuck and thus permanently pressed.
This causes the permanent reboot, because holding the power button for a certain amount of time causes a reboot.
Try to push "Vol down"+"Homebutton" instantly after a reboot. If your galaxy enters the download mode (before rebooting again), you have the proof, that it's the fault of the power button due to the fact that pressing the power button would have been necessary.
I hope the fix will be for free under warranty.
At the first moment I also thought it would be the Sudden Death syndrom, but thankfully it's not the case and only the power button has to be fixed.

I don't know, i didn't paid attention to it. Anyway thanks to both of you for the replies, i'll check the power button as soon as possible since i don't have the phone with me right now. If that's not the cause, i think i'll do an emergency recover with kies as suggested by Cy4n1d3.
Now i still have a doubt, CM11 should have the fix for the sudden death syndrome merged into its code right? I'm asking this because if i'm right i could exclude sds as the cause of the problem...
Rebooting is not an SDS symptom, SDS is totally dead -suddenly.
Power button failure is diagnosed by inserting the battery, if it turns on by itself then button contacts are shorted out.
Your problem sounds more like corruption of the cache or dalvik, wipe and reflash your rom or go back to stock to test. Check MD5 of downloads and don't restore anything before you test.
I was checking Facebook when suddenly the phone restarted, but it got stuck at the first boot logo over and over...then i tried several steps to figure out what's going on.
*First I took the battery out, leaved the phone without it for about 5hrs, then I put it back and no luck... (The SD card was also removed.)
*Later I tried with a different battery and no luck, the phone keeps restarting over and over...
*Tried entering in Download mode and nothing works, the phone does not respond, and then it restarts...
*Tried doing a hard reset, but the phone does not respond to (vol up + home + power)
*Changed the SD card with a new one, nothing.
*The battery is not swallowed.
*The device was rooted and running Omega ROM V17 Android 4.3 (rooted it in December and had no problem).
WTH is going on?, if at least i could use download mode to fix it
(another thing that looks strange to me is that as soon as I put the battery on the phone, the device turns on intermediately and I think it's not normal because the device does nothing until the user turns it on.)
Please any help, this issue is over my head.
Thank you so much.
Download mode and recovery is available??
It can be 2 things:
- You have a faulty battery.
- You have damaged hardware.
No flash is going to help you. It's just bad luck.
Probably your power button was broken and stucked. If you still have warranty, send it to repair in samsung service center. This used to happen to my i9500 once.

Hi guys,
I have an issue with my phone:
Yesterday, tried to restore factory settings, since the phone was quite slow.
A second or so after I confirmed the reset, the phone turned off and wouldn't start.
I took out the battery and it was swollen.
I bought a new battery today, inserted and stated the phone.
What happens now, is that the phone boots, Samsung logo appears, then the TWRP logo appears, from this point, the phone stuck at this logo screen,
and flashes every few seconds (I can't post a video here, so I can share the link in private, if anyone can take a look).
I tried to leave the phone for about 20mins without battery at all, removed SD cards, removed SIM cards, no use.
Trying to boot to recovery or download mode gives the same result.
Tried today with an original battery of a friend's Galaxy S4 , same result.
Does anyone have an idea what I can do?
Thanks in advance for you help

Sound to me your power button is stuck/faulty. Does it reboot also when in download mode? If so, then it's your power button. Wiggle it loose or replace it.

It never gets to download (or recovery) mode...
It keeps flashing at the logo of the TWRP
Trying to boot to download or recovery modes, gives the same results
I don't think it's the power button. Otherwise it would turn off if it is stuck or not turn on at all if it's faulty.
Still, I wouldn't exclude it.
The screen flashing might related to a GPU problem. I don't think it is a problem you can fix yourself.
Im so lost with this, im all stock but one day my phone just freezes then bootloop, I would be able to get it work by just leaving it and let it drain itself since it will be boot looping and lock me out completely, like the power button + low volume button would not work even after 10 minutes of holding it, would not boot to download or recovery mode, just the soft touch keys light on and the blue LED.
I reflashed my ROM from sammobile yesterday but did it half-effort, just dirty flashed it but it seemed to reformatted my phone anyway, after reflashing it, everything seemed to work properly for 20 hours and then now im back to this piece of ********* boot looping...
S7 Edge
running the Australia unbranded XSA-G935FXXS1DQG4 from the branded G935FXXS1DQG5,
would flashing de-branded affect this? or this is hardware?, one thing I did that I think was a mistake is that I chose to restore from old device, can apps cause this?
the very first time this happened, I plugged it in to charge then crash and bootloop.
UPDATE:
Things I've tried,
-Booting with NO sim card and SD Card
-Wiping cache and partition then reflashing stock XSA and OPS firmwares
im convinced that this is a hardware issue and will go to Samsung.
mine does this too. crashes then gets into a bootloop at the Samsung logo. I usually try holding the lock and volume down button. I factory reset the phone once but it still keeps happening, this started happening around 4 weeks ago
Guys your Main/Mother-boards are broken.. u need to replace it, or send back to Samsung..
Damn! Crash reboot samsung logo
Damn you say broken mother board...
did this. Press vol down, power button and home key...hmmm... i think...pressed so many combos hard to tell themapart
Hi
I am stuck with Pulsing blue LED and the "Powered by Android" screen,
have access to both the recovery and the download Mode,
I also have Odin (version 3.13) on my computer along with TWRP (3.1.1 trlte and 3.2.1 version)
My device is a Samsung Galaxy Note 4 N910F bought in shop, no special carrier. It was bought in the Netherlands.
I have tried everything that I have read. The furthest that I can go is the Second Samsung Logo with the Flashing Light
Whenever I try to Flash the stock Firmware for my N910F, everything goes well in Odin but then when the phone reboots, it (sometimes) install the system update until 30% then shows erasing then either crashes right there and then or load the system update bar, completes it then shuts down.
I have tried multiple firmwares, even recovery firmwares. All the same problem. I can see the firmware is flashed, because when I enter recovery mode after I flashed a different ROM, it shows the version I flashed.
I cannot seem to install TWRP because it was never rooted.
Whatever I do, at some point, my phone either gets stuck in a bootloop, freezes with the LED light or shuts down.
And I have also proceeded to use different batteries.
Do you have any options?
Thank you
Heat????
I'm far from an expert here, but I've just experienced a similar problem where my N910F started boot looping / freezing within 15s to 2 min after unlocking. Unfortunately my micro Sd (SanDisk 256GB) was corrupted a week ago, so before doing anything else I did some research (XDA/YouTube) and probably found pretty much what you've found. I frequently change batteries so I could discount that as an issue. Someone suggested using the Samsung Smart switch here https://www.samsung.com/uk/getting-started/smart-switch/, but I haven't used it (yet) so I can't tell. I presume you had the latest firmware from Sams https://www.sammobile.com/firmwares/galaxy-note4/SM-N910F/.
My issue was that I needed to recover data, docs, photos, phone numbers etc. When boot looping the note 4 got very hot . In particular around and to the left of the camera (looking at the rear). Thinking it could possibly be the dreaded eMMC problem which also manifests itself by creating heat, I thought cooling the device might help. I placed the Note on a cooler box freezing block and voilà! No boot loop. I was able to remove all, but necessary apps and do a full copy to my PC. Storage was reduced from around 90% to 50% and memory 80% to 60%. It's now been stable for 12 hours, but the jury is still out. Next will be full reset with he latest available firmware 6.0.1 as mine was still on 5.1.1.
Good luck and hope this may be of some help.
I've got this problem, too, when using the unofficial Lineage 15.1 rom. SIM death and boot loop. After flashing the latest stock rom through odin, it passed but the screen was black and no system was installed. The blue notification light was constantly stuttering, though. And I couldn't even go to recovery!
When flashing, a 910F can get hot - use a cool temperature room and/or a fan blowing onto the device.
If it's not too late...
