[Q] Stuck in bootloop even after battery change

Hi,
I am new to this forum and do not know much of the technical terms. So here is my problem as best as I could say...
I have a unlocked Samsung S4 purchased last Sept (Philippines/SE Asia version, I think). The phone worked fine until the latest upgrade to Kitkat 3 weeks ago.
A week after the upgrade, the phone started rebooting itself. After checking this forum, it looked like a battery problem. On checking, it did have a swollen battery. At the same time, the S4 stopped working as a phone - meaning I could browse, use apps, but could not make calls.
First changed the battery with an original from Samsung, hoping everything would sort out. Unfortunately, it did not. The phone still kept restarting and the network signal showed as not available. So I went to my provider and got a new SIM card and changed it.
Unfortunately, that has also not solved my problem.
Now, my phone keeps rebooting itself. If I connect it to the charger, then the phone starts successfully. At times, it behaves well, but suddenly/randomly, if I touch an app (any app, no pattern) it will reboot again. Once it starts rebooting, it keeps doing that in the screen which has the samsung music comes - it would turn off again and keep restarting until that screen reaches again. Only if I connect to the charger would it start. Again, there is signal at times and there is no signal most of the times. My area has good network signal, so that should not be the problem.
I tried clearing the cache and clear all data/apps, but still no luck. Also, my battery still has / holds charge - so that is not the problem.
Could somebody please help me!!! Please let me know if you need any other details regarding this.
TIA.
Baseband version: I9505XXUFNBE

1. Sig & log in Sammobile.com
2. Download ur firmware: HERE
3. Unzip it
4. Phone in DOWNLOAD MODE
5. Flash the firmware through ODIN like the pic attached

It has nothing to do with your battery...but yes a swollen battery can be dangerous. Follow the steps told by @Joku1981 and don't upgrade to kitkat. Wait for a stable release from samsung.

Hi,
I have already upgraded to kitkat, so cannot downgrade now.. . I had the request to upgrade to kitkat by the phone (Samsung).
As mentioned by Joku1981, I downloaded the Philippines firmware and did as mentioned. However, the phone was still randomly shutting down on opening some apps (esp Gallery, Playstore, Chrome) and failed to reboot.
I also tried to download the pit file and flash it again as mentioned in http://forum.xda-developers.com/showthread.php?t=2265477. Still no lock.
I tried with UK's version of firmware, still same problem.
The phone can be restarted only if connected to the usb cable.
The "No Signal" issue seems to have been solved, but the rebooting randomly seems to be a real pain now.
After my latest flash, while i was in the third screen setting up the phone for language/accessibility --> "wi-fi setup" --> "Accept Samsung t&c's", the phone shut down again...
Is there any counter to identify the number of times the phone is flashed? Would it cause any problem?
Thanks

Also No Service now!
Also noticed that after the last 2 restarts, the network signal shows full strength. However the default lock screen shows "No Service" (see picture). When I try to call when the phoneis in this status, the phone gets stuck in the dial screen and has to be rebooted...

Though you flashed, do a factory reset one more time to be on the safe side - make sure the phone is 100% charged, and given your case do NOT touch the phone until the reset has completed.
One more thing to try - from experience some batteries are bigger than others and you said your previous one became swollen. This may cause the power pins to become too compressed causing the new battery to lose contact. This manifests on the phone as rebooting at the slightest of movement/flexing, try this:
1. Remove the battery
2. GENTLY pull out slightly the power pins on the phone - don't pull too hard.
3. Put the battery back, put a piece of cardboard or something at the bottom of the battery to make sure there's good contact
Let us know of the results

Nothing seemed to work but only got worse. The phone could not stay on even for a few hours. Finally gave it to the Samsung Service centre yesterday. They sad it might take upto 3 weeks if there was a motherboard change needed.
Fingers crossed...:crying:

Note 4 rebooting almost every day randomly

This is my second Sprint Galaxy Note 4 (the one I had previously had issues reconnecting to WiFi networks after going out-of-range and switching to 4G, and even more annoyingly the battery would die even if fully charged if I took more than one picture at a time) and I haven't even fully set it up or installed that much on it and now it seems to be rebooting almost every day at random times. Some days it reboots several times in the day. I have no idea what is causing this, but is there any troubleshooting or diagnostic testing I can do to figure out why this is happening? Or does anyone have any suggestions for how I can either figure out what's causing this or fix it? The phone is running:
- Software version: N910PVPS4DPD1
- Hardware version: N910P.05
- Android version: 6.0.1
- Android security patch level: April 2, 2016
- Baseband version: N910PVPS4DPD1
- Not rooted or otherwise modified aside from settings changes and installed apps (and international unlock done by Sprint)
Thanks in advance for any help!!

Have you tried leaving it 1 day running in safe mode, to see if it also occurs there?

Shake it around in different orientations and see if it reboots. May be the battery is loose and momentarily loses its connection.

You'll have to forgive me - I'm not familiar with safe mode on the Note 4. Can you advise how to get into it, as well as what limitations there are with it (i.e. can I continue to actually use my phone to do things while it's in safe mode, since I heavily rely upon my phone every day)? Also, I'd probably have to leave it in safe mode for a few days, since it doesn't always reboot every day, and even if putting it in safe mode prevented it from rebooting randomly, can you advise how that would help diagnose the issue? Thanks, and sorry for all the follow-up questions!

I was actually thinking about that since I went to a wedding over the weekend and had the phone in my pocket while I was moving around a lot (i.e. attempting to dance...lol) and it did reboot several times that night alone. However, it has also rebooted while entirely stationary (such as overnight while it's resting on a flat non-moving surface next to my bed) so do you think a loose battery could still actually be a cause?

The software might be the cause, I can't say for sure since im running cm13.
Anyway, I believe you have to long press the either the power or reboot option to enter safe mode.

Safe mode disables all user installed apps to see if one of them is causing the issue. Just tried it and as soon as the first splash screen starts up hold volume down only all the way through boot up. It will say 'safe mode' in the bottom left corner.
From another site:
Safe Mode isn't meant to be accessed regularly, so it's understandable that the function is stuck behind a pretty convoluted method. If you want to access Safe Mode, power down your phone completely — hold the power button, then select Power off from the menu. Once the phone is off, press and hold the power button to turn the phone on, and as soon as the "Samsung" logo pops on screen, release the power button and then press and hold the volume down button until the phone boots up completely.

Have you tried doing a hard factory reset on your device but clear the cache in the hard factory reset menu first? That might fix your problem.

mmc_read failure Note 4 n910w8 Rogers!!

Here is the story,
I flashed Marshmallow on my note 4 n910w8 via odin (I had 5.1.1). After it was done I noticed that the phone got laggy and warm. It would sometimes not boot/restart or it would shut down after it freezes for sometime. I would get the download page with mmc_read failure in red, I would pull out the battery and try again.
What I did:
*Unrooted the phone through SuperSu and flashed Twrp throughout (because it gave other errors and I had to do it again and again after each attempt)
*I tried flashing through twrp but I got the "no md5" error
*Flashed the stock ROM 6.0.1 with PIT since it gave the PIT error on odin
*Wiped cache/data/factory reset multiple times.
*I used both Kies and Smartswitch and was not successful (either read or write failure)
*Flashed the stock 4.4.1 (the original, It could not boot up once) so I returned to the stock 6.0.1
*The phone boots up 3 out 5 times and I was able to watch a full movie on Netflix and browse the web and google maps. But as soon as I locked it, It shut off and did not power up (until i took out the battery and let it cool down).
Where I went:
*A Samsung repair agent here in Montreal said that most of the time it is the Mob and that it would cost 300-400$ CAD to replace
*I went to other repair shops, a few hinted that it might just a matter of reprogramming the Mob and that it involved a risk of bricking the phone for good.
N.B: It is not under warranty and I'm not on contract, It is my own phone.
My question(s): Is there something else I could try? Is there someone who fixed the issued (Assuming it is not hardware) maybe and unbrick fix or something? And also, it there anyway to thoroughly wipe out the old installations so I could start anew?
Also I consider myself pretty knowledgeable. Or I at least learn quick. Do not hesitate to suggest something coarse for me to try. Worse comes to worse, Ill sell it on eBay for part, since it it in mint condition.

It's definitely a hardware issue, trust me.
But all the problems can be bypassed by rooting your device and installing Wake Lock app from the playstore and activate PARTIAL_WAKE_LOCK, enable the notification and start on boot. This will fix all the lag and the crashes.
This will not, however, fix the boot problems. So if your device ever runs out of battery or turns off, booting it is gonna be a hassle still as before. If you ever get stuck trying to boot it properly to homescreen however, I discovered a foolproof method for that with 10/10 success rate.
I know it might sound weird, but I'm seriously not trolling you. Take out the battery and place the phone & the battery in your fridge for at least 5 minutes until your device gets cold. Put the battery back in and boot into 'download mode'. You'll notice that it'll goes into download mode perfectly. Take out the battery again and just boot normally. You'll be back into homescreen in no time. This is how I know it's a hardware problem, lol.
With these alternative fixes, I'm hoping that I can keep my phone alive for at least another 2 years. Better than forking out another $500~ for a new device imho.

Thank you very much for your reply, I take it you have the same problem? I will try Wake Lock. And also I'm way ahead of you in the freezing game. Leave for 10mins in the freezer and you can basically flash anything. Also, do you a custom ROM would help?

Help with troubleshooting - bootloop, calls restarting phone, wifi won't turn on

I've been having some problems with my Galaxy S5 recently after ~2 years and some change of owning it. I'm stock rooted on the original ANCG KitKat version.
The problem: If I power off my phone, it will cause it to go into a bootloop, not going past the first screen (Samsung Galaxy S5, powered by android). I haven't found a reliable way to fix it from the loop, but I usually just remove the battery, wait, and try again until somehow it just works and boots up. This is extremely problematic because sometimes my battery runs out and after charging I'll have to go through this game of chance again until my phone works.
The next problem also adds to this frustration as well. When I attempt to pick up a call, my phone will sometimes just not work and restart itself. This leads to lots of confusion and I can't call them back for some time because the phone is stuck in a bootloop.
In the few times that I do get my phone to actually boot up, everything works fine except sometimes my Wifi just doesn't work. It gets stuck on "turning on" where the notification drawer quick setting icon is dim green and never gets to the turned on full green state, eventually just turning itself off (no green color).
I haven't done a factory reset or any real troubleshooting yet, as I'm a bit worried I won't even be able to boot up the phone and I don't have the time yet to spend a full day fixing it. Any help would be appreciated, thanks!

The calling problem may be caused by the google dialer app not being set as the the default phone app but as for the other issues i have no idea a factory reset is a good start though

unfortunately I had the same problem but I have marshmallow but the factory reset helped with the not booting up and see a big difference with the battery

Trusty Note 4 Booting Issue!!

Hey guys, I have had my Note 4 for about 3 years now and it has never done me wrong. However, things have taken a turn for the worse... I started noticing a few days ago that it was slowing down on me, I mean, really slowing down. Big lag times when it comes to swiping to open the screen, or changing between apps, and the occasional self-shut down when the battery got down to about 15-20%. I had been putting off doing a self-update for a while, and when I finally had time to do one tonight, in hopes of cleaning it up, it is now lying on its death bed
I do not think the update ever finished (my phone is not rooted) but I was desperate enough to even do a factory reset and that has not fixed the issue.
Here are the symptoms:
As I go to boot the phone, I get past the Samsung Note logo and it looks like it is about to load properly, but then I get a popup that says "Unfortunately, the process com.android.phone has stopped" I hit ok and it keeps popping up again. I can't bypass it.. Then after I get passed that for a split second, another popup comes up that says "unfortunately system UI has stopped" It prevents me from getting to the home screen, in fact the screen behind it is black.
I have tried the following:
Clearing the cache partition from the recovery screen
I have done numerous hard restarts
I have gone through with a factory restart
That is where I have left off, and lost most hope, was with the factory restart. Now when I turn it on, I get past the logos and I can see in the background the page you would get as if it was a brand new phone (it says "Welcome! Preparing you device for first time use.." etc. But I can't do anything about it because I am still getting the same two popups that prevent me from doing absolutely everything!!!)
I have read about this happening and people seem to be able to fix this by accessing certain app setting and either resetting them, or clearing their cache. However, that is not an option for me because I can't get that far. I think something must have went wrong during the update...
Please help with any advice you can think of. I have been putting off rooting this phone pretty much because I was afraid of royally f****** it up, but at this point I am willing to try anything.
Thanks,
Eric

Hey guys, does anyone have any suggestions for my issue?? I am about to go out and buy a new phone, I have no idea what I can do to fix this. I have rooted it using Odin, but the popups are still occurring. I can't get the popups to stop, and they are preventing me from doing absolutely everything.
Is there anyway I can get it to go back to complete scratch? Again, I have done a factory reset, cleared the cache, rooted using Odin. I have done everything I can think of/what I have read I can do. I am willing to try anything at this point.
UPDATE: At this point my phone is on, and the only error message/popup I am getting is "Unfortunately, System UI has stopped." Behind that popup is a blank, black screen. The only option I have is to click ok, and the screen remains black.

Temporary solution that might work- Try logging in safe mode: Switch off the phone. Power it on and as soon as Samsung logo appears, release the power button and press and hold the volume down button. Release button when you see Safe Mode on the lower left corner of the screen. Try uninstalling all user apps in safe mode. To get back to the normal mode you can drag down from notification and disable safe mode.
You could also download the latest software for your model from samfirm and flash it via odin after factory reset. Could be a permanent solution.

why you just flash last frimware from sammobile,it will solve all your problems

SOLVED!!!
Alright guys, I was able to solve my problem, all thanks to this thread:
https://forum.xda-developers.com/note-4-sprint/general/stock-tar-odin-flashable-t3250864
I had already tried flashing a fresh stock rom, but to no prevail. I saw this thread and thought, hey why not give it a shot, and bingo! After downloading the .tar file for marshmellow and launching it through odin, she was good as new! So if anyone seems to have a problem with the system ui or the process phone.android popup, I suggest that thread.
