hello dear xda,
today i have suddenly experienced my phone dying :
it is constantly trying to turn on, going to samsung logo and then turning off, as long as the battery is in it does this without me touching anything..
even if i try to boot into download mode it goes into it for 5-10 secs while i cant control volume buttons at all and reboots again, while i cannot boot at all into recovery
volume buttons seem to work because it lets me go into downloadmode confirmation screen ( to either reboot or continue )
im thinking battery might have died but im not sure.. because it might be the rom just bootlooping
i have searched the forums and internet for a solution but did not find any
i was on ressurection remix rom with GALAXY S 4 I9500 variant
please help and thanks in advance! :crying::crying:
What you're describing sounds a lot like your power button is stuck in the pressed position.

that does not seem to be the case sadly..
thanks for replying
Unfortunately, it seems to be a hardware issue, rather than software. I have installed tons of custom ROMS on my S4 so far, and I haven't had any issues of that kind. Something is wrong with the hardware I guess...
As I said, I'm pretty sure it is the power button. I've seen this behavior before.
When the battery is dead the phone won't even turn on.

Just had the same problem, re-soldering new power button fixed.

Definitely a power button issue. The giveaway is that you say the device starts this boot/restart cycle as soon as you put the battery in (without you pressing anything).
No two ways about it....
It *IS* a faulty power button.
I have seen this issue on other Samsung devices too, and every time it's been a faulty power button.
My last s4 seemed to have the power button problem too, would reboot, logo, reboot.
Could interrupt the rebooting by holding volume down to go into flash mode, would remain stable until battery eventually died.
Couldn't boot into custom recovery, with volume up, which almosts confirms the theory, because holding power button down may reboot it from recovery.
Occasionally, I could get it to completely bootup, use it for 3-20minutes before it would shutdown.
I used multimeter to confirm operation of the switch was correct. Seemed to work fine. But I never actually removed the switch.
Decided to just replace the logic board and deal with it at a later date.
Reading about this again, I might go ahead and desolder the button, this weekend, and check functionality.
My conclusion was that I had some degradation in the internal memory storage, that affected the recovery/bootup or some heat damage
My device first decided to shutdown and go into reboot loop whilst using it on a long journey, I was using Google navigation and youtube in multiwindow mode, and the device was toasty warm.
@reluctant_traveller your issue is probably not the power button unless you have a fault with the button that is intermittent (extremely unusual..but not unheard of). Faulty power buttons are *usually* in one of two states...either open circuit or closed circuit. In one state the faulty button will cause a continuous reboot/shutdown/reboot cycle every 10-15 seconds until the battery is removed, in the other state, you'll get no reaction at all from pressing the button. The fact that you say you had the device up and running for between 3 and 20 minutes points to it being something else.
Yep, I keep meaning to investigate further before binning the board, I will definately grab my hot air gun and try and see if I can get it to power cycle from adb mode.
It is possible that the thermal pads are not taking the heat away from the cpu, possibly due to movement or overstress.
The screen did used to get very hot around the position the cpu would of been.

Hi all, i have a ZTE blade which i have rooted and flashed CM 7.0 successfully without upgrading the radio to GEN2. I've done this and much more without problems, however today for some reason the phone isnt even powering on. The only thing i did before was installing theft aware 2.0. Note that i dont have a SIM card inserted so it's unlikely that someone have sent a command that turned the phone into a... vegetable.
I tried removing the battery and trying to turn it on, nothing. I tried connecting it to the USB power charger without a battery, still nothing. This phone is supposed to be a birthday gift for my friends 30th birthday, so i'd really appriciate help getting it back to life.
Thanks in advance
EDIT: I've tried the following: with ADB devices the phone dosen't show up.
Trying entering field test mode with VOLUME DOWN + POWER key does not do anything. same result with VOLUME UP + POWER.
Tried different USB cords without success.
Have you tried holding volume up & down together along with the power button. Make sure you have the usb cable connected from the phone to a pc. So long as you have the zte drivers, it should show up in DFU mode in device manager (from what I remember).
I think from there you can flash recovery using fastboot again.
I tried that, nothing happens. Thing is, the phone dosen't give any kind of life signal at all, not even the button backlights turns on during charging. Could it be that it suffers from a hardware defect? Or is there more things i can try?
Yeah sounds like you may have a hardware issue; especially if none of the LEDs flicker on when trying the above.
hmm, ....out of ideas for now fella.
Any news on this?
I am having the exact issue, phone is like a real brick:
- Won't do anything when trying to press power and/or any other buttons one by one or at the same time
- Won't do anything with or without battery
- Won't do anything when pluging it to the USB/Charger, not even a led response
- I've tried with and without sim, with and without sd card, trie everything and still nothing, seems complketely without any kind of life inside. The only thing it does is get heat when you put it to charge with battery
I had it with cyanogen 7, max overclock to 710mhz, min arround 200, and it happened (turned off) 5 minutes after I installed Launcher Pro...
Any ideas?

I actually gave up and sent it in for service which returned me a brand new one. I suspect that ZTE dosen't have much of quality controls since a friend also suffered a case of "true-death" on her unmodified ZTE blade...
Similar issue here. If I press the power button (with or without any combination of other buttons) it just vibrates - no lights, display or sound. Doesn't power on so no fastboot/adb etc. Same behaviour with battery, charger, or both. If I hold the power button the vibration sort of pulses, a vibration every 0.75 seconds or so. I recently opened it up to get dust out from behind the screen, so no warranty :-(
Will ask at the shop what the options are for maybe paying for a repair..

Your issue is different than the one i had, you phone is at least being powered on since its vibrating.
Most likely you broke when you opened it or you simply didn't reassemble it correctly - if i were you i'd do it again and check that all the connectors are connected.
If its a software issue, you can always try TPT - total phone transfer. google it, i read it but didnt try it myself so i cant vouch for how it works.
does anyone here encountered this kind of problem and fix it?
last night i turn off my phone and charge it. after an hour i notice that its very hot. in sim card tray area and in memory card tray area. even the front screen suffer from that over heating but the battery didn't heat at all. the first time i try to turn on the device the samsung logo appears but immediately shutdown. then i let the phone cooldown for 4-5 hrs thinking the problem will be fixed. but after i try to turn the phone again nothing really happening. no vibration, no samsung logo nothing at all. and when i try to charge again it via pc and via power plug it's not charging and after 2-3 minutes the my phone is starting to become extremely hot again.
i already tried to press and hold volume down + menu button + power button
volume up + menu button + power button
holding all buttons + power button
removing battery and hold power button for 1 min and put it back again and power button
all that nothings happen.
can anybody here thell whats the problem of my samsung galaxy s4 i9505? i will be extremely grateful for your help. thankyou

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.
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.

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 got a new update for my phone and after it finished applying, my phone won't turn on. The screen is black but when i plug it into my computer i can hear the usb jingle. I tried all the button combinations but its unresponsive.
Anyone know whats happening?

Did you take the phone in for service? What did they do to fix it, if they fixed it... I have a dead phone and need some answers if they are out there. I'm looking through every post that has anything to do with this subject and coming up blank - just like my phone's screen!
Part of my issue is that I had a shut down from out of nowhere on NYE. I was able to bring it back up with the power, volume up, and Bixby combo the next day. Foolishly I assumed it was a fluke and went right back to using my phone just as I had before. I saw an article about disabling the Bixby button, which seemed to be the thing to do... When the phone shut down the next day again, I couldn't bring it back because I no longer have a Bixby button for the combo. It's been down since Jan. 2, and I'm at my wit's end. Can you please update your phone status? I'd appreciate it if you can!

Lol disabling the bixby button in software does not mean you can't trigger download mode. That level of software has no idea what packages you disabled ?
Did you have Substratum themes applied before updating?

Happened with me last night, bunch of updates and then black. I was gonna send to warranty, then someone told me Power + Bixby + Vl down and it worked. How can I find out what did it
When I called Samsung, they were clueless how to get it started again as we walked through all the button combinations they had. It was fully charged when it stopped working, both times. The second time it took me a few days of trying on my own, calling, Samsung and then going into their repair store.
They took it back to work on it after I explained what was going on. He tried several things and came out and told me it may need a replacement but wanted to try one more thing. Hours later, he came back and said he hooked it up to a charger and it had been dead. Once it started charging, it showed the green battery, lightning bolt and blinking circle. It still didn't start normally, but the three button combo worked at around 20%. I'm not sure if he tried before that, but it came back on.
I've discovered that my handset is extremely sensitive to cold temperatures and shuts down. I'm in the Midwest and have been working outside in a tent like structure. I listen to music, books, or podcasts while I'm working. Many times, I will put my phone on a shelf while charging but still listening. The phone shuts off and first I have to wait for it to warm up, then it has to drain the fully charged battery, and then I start charging it again. After the first time on my own, I did the button combo right after it started taking a charge and it worked.
I'm not sure if a replacement phone is the way to go, because if this is common on the S8, I might end up with another dud that would just frustrate me more. I like the phone, but this quirk is annoying.
Last night my phone was charging and accessible fine. This morning I have a green light at the top showing I assume that it's charged but the screen is totaly black. nothing I do brings up any screen. I tried all the button combos I tried plugging it in to the charger and nothing shows any kind of reaction. I tried plugging it into my computer and the computer said it was setting up device QUSB_BULK. Then said it was set up but even after it supposedly complete I could not find the device. What the hell?
S8 Black Screen
Is the green light staying on? This happened to me on one of the many shut down times I experienced. I think I narrowed it down to my phone not liking cold temperatures, but I don't know if that is your phone's issue. It hasn't happened since last winter, so I haven't needed to do any of this for quite some time, but I'm trying to remember all of the steps I took.
I'm gonna suggest getting the battery drained back down to zero. In order to drain the battery when it's black screened, I kept trying all the button combos repeatedly for, it seems like, maybe three or more days... I couldn't tell if it was dead on several of the occasions, but when I had an indication light, it went off after days of doing any and all button combos, just to drain what battery I could.
Once you do that, while keeping it out of any extreme temps, (if there have been any) then plug in the adapter that came with it, using a good quality USB-C cord and charge it again and see if the charging screen comes up. (The Fast Adapter Charger that connects with USB 3.o is the best to use. Samsung wanted me to use the original cord, but I have no idea where that is! I just used a good quality cord.)
If that doesn't do the trick, then it's not the same issue I had, and I wish you luck on finding out and getting it fixed! Don't forget to update the site for others to find out if your tricks work... (You can still try this, but it may be just to rule it out as a possibility.) Try draining it more than you first did, and then plug it in again to see if it takes a change.
If it is taking a charge again after draining and plugging in your power cord, wait until you get back up to at least 20% and then try the three button start (Bixby / Power / Volume Up at the same time) and make sure you hold them for up to 30 seconds or until it kicks on. One time, I think I held it for almost a full minute. But it did take the change, restarted on the three button combo restart, and didn't have any new issues from its down time.
If this works for you, come back and tell us! If not, come back and report what you try and what the results are.
I really hope that helps! Good luck!

Sounds like a system problem, you can try to use the button to force a reboot, if there is no response, you can try to reinstall the system, if this still can not be solved, then you may need to replace the new screen, you can go to Witrigs to see Note 8 screen, they There is an original Note 8 Super AMoled screen for sale. The price is also relatively low.
The device will not boot up. Every 15 seconds, the device vibrates once and the notification light flashes once. Only holding all three buttons stops the vibrate/flash cycle. Holding any other combination of buttons does nothing. Nothing shows up on the screen during the vibrate/flash cycle. My computer also does not recognize the device when I plug it in, whether in its vibrate/flash cycle or after I hold all three buttons. I would very much appreciate anyone's troubleshooting ideas on this, and thanks for your time.
Had a similar issue after my phone started to reboot itself numerous times a day. What worked for me was pressing the power button for about 45 seconds. That stopped the vibration loop and powered the phone back on.
Maybe you need to let your battery run empty if the power button trick does not help. Also worth checking the USB-C port for any dust or other ingressed matter that might cause some pins to conduct and confuse the phone.
Good luck

Thank you for the reply. I don't think what my device is experiencing is really a restart, though I could be wrong. Nothing shows up on the phone's screen, and it does this repeatedly every 15 seconds until I hold all three buttons.
Is there anything that I could check internally if I took the phone apart? Maybe a connection worked itself loose?

Holding the power button for over a minute doesn't do anything either. I used a can of compressed air to gently clean out the USB-C port, but nothing was obviously bent or deformed. I'm not sure if it's charging, because after pressing all three buttons to stop the vibrate/flash cycle, the notification light doesn't stay lit red or green while plugged in.
I understand that many things could likely cause this, but I'd really appreciate some troubleshooting ideas here. I'll be taking the phone apart this weekend to inspect all the connections. I have experience building desktop computers and laptops, but other than that, I won't be able to spot, for example, a gpu or processor that isn't set correctly. Any tips for what else to look for would be extremely helpful.
Battery health? Last ROM? Nougat/Oreo? Stock or Custom ROM?
Does ZTE splash screen appear on boot? - Could be lcd connector.
Does something change in hardware manager?
Tried different usb-c cable?
Does device is in EDL/DFU mode when 3 button are pressed?
Had a bootloop similar to yours, but it was on stock nougat rom and screen worked. It was long time ago. Fixed by grounding test point and flashing edl package.

I recall that the charge was reading approximately 70%, but I can't speak to health. It typically wasn't draining quickly for no reason and would hold a charge.
I believe it was running Android 7.1.1, kernel version 3.18.31, build number A2017UV1.1.0B35, from a previous post of mine when I included this information.
Stock ROM, and nothing custom about this setup.
No splash screen appears on boot. No image appears on the screen.
I'm not sure what you mean by "hardware manager". How can I check that?
I can try a different USB-C cable tonight.
I believe the device enters EDL/DFU mode when the three buttons are pressed, but I don't know how to confirm that. It just stops the 15 second vibration/flash loop.
Could you provide a little more information on how I can flash the EDL package? I plan to do more research and disassemble the phone this weekend.

I've tried all the chargers I own, which include different USB to wall plug adapters, and the phone doesn't appear to be charging (red/green notification light doesn't illuminate). Though, when it's plugged in, the vibrate/flash cycle starts again.

Hello, my zte axon 7 fell from my lap face flat on a tile while I was using it, and ever since then it won't come up, no notification light, no logo, just nothing, when I charge it, it just warms up a little and my power bank indicates it charges. I used the video to disassemble the phone today and I still couldn't find anything disconnected. Does it mean the phone is dead. Any advice please
