Hey team! I replaced my screen from a local vendor:crying:. my phone keeps on Restarting itself. After many Reboots it finally booted up. but whenever i pop in my sim card and turn on mobile data it keeps on rebooting. and whenever i go into security settings for setting fp this issue occurs again n again. even fp is not working
*Tried factory Reset
*wiped cache
*Tried custom Roms
The time i gave him phone was rooted. so i thought might be Root issue. so i flashed stock rom with build no. NPJ25.9-14. and Relocked the boot-loader. But the problem was not solved so i tried flashing customs Roms. but the problem wont solved!!
After many Reboots it works perfect till the time i switch on my mobile data and setup my fp.
Idk what is the problem but it is not a software issue. because i even tried flashing marshmallow. but same results
Help!!!!
Seems like your device is done. There might be some motherboard issue I guess. Visit authorised service center only.

r.i.p phone.
imo you should've repaired it yourself. Replacement LCDs are only $40, and repairing the phone isn't hard at all.
Sounds like your repair vendor ****ed up your motherboard.

Hello,
I have a problem with my i9505. The phone had been rooted with stock ROM. I've installed Avast Antivirus and decided to install Anti Theft feature. Installing it requires reboot. After confirming rebooting the phone beeped twice and rebooted. And this is where my problem begins.
After reboot the screen is black. It shows nothing. The phone boots, LED shows charging, connecting and disconnecting charger makes phone beep, but with few seconds delay. Connecting to PC shows content of phone memory.
I have managed to get to recovery. Odin had seen the phone so I've flashed official Samsung ROM. It didn't help.
Surprisingly after few hours with battery removed the phone started to work normally... until the next reboot.
And now it works until the reboot. After reboot the screen is black. After about 30 minutes without battery it works again.
The phone never got dropped or damaged in any way.
Before I get my phone to the service (hoping that they'll fix it under warranty) I'd like to ask you, if somebody had similar problem and knows how to fix it.
Thanks in advance.
Same problem on same phone
Hi,
I too had this problem, and fixing it wasn't difficult, however I used the TWRP recovery which @ingvarr_zaag probably doesn't have installed (seeing as they had stock firmware). Nevertheless I can confirm this identical problem on my own i9505.
I was using a CM10.1 nightly build for my i9505 and attempted to install the AVAST Anti-Theft feature using the root install method. On the first attempt at installation there was a free-space error, in which the amount of free space shown in the /system partition had overflowed and showed negative free space. To work around that error I filled up my /system partition until there was only 100mb free and then the install worked. All went well until I did a reboot; the phone hung at the i9505 screen.
I tried rebooting the phone and removing the battery for a short while, but nothing worked - the phone still hung at the i9505 screen. However, all other functions worked, so I just reflashed CM10.1 after wiping /cache, /data (but not /data/media), /system, and the Dalvik-cache (though that is in /cache AFAIK so pretty redundant). All was fine after that reflash, other than the annoyance of having to set everything up again (didn't make a backup recently).
Obviously the Anti-Theft wasn't very secure if it could be removed by a simple reflash. But to be fair, I highly doubt any software can protect itself from a format!
Anyway, just letting people know that I can confirm this this problem exists, and how I fixed it on my phone.

I had Clockwork Recovery installed but I couldn't use it, because after reboot the screen was black. I managed to get to android recovery and flashed stock Samsung ROM by Odin. It didn't help.
After 2 weeks in service it's possible that today I get my phone back. Finally, because two weeks with Samsung Galaxy Advance were miserable.
Actual status on service's page says, that they replaced main board in my phone.
BTW: no Avast Anti Theft ever again.
Hi guys, i'm having big issues with my phone.
I was on imperium lollipop Rom, everything went fine, and i began to have call issues (bad reception quality), so i decided to update my modem & bootloader to the last lollipop ones. Then i installed a S6 port rom (by albe95), and my phone became crazy.
I have random reboots, shutdowns, sometimes i can pass through the simcode and i use the phone normally, and then it restarts like infinite times, i have to remove the battery. I wiped data, cache, dalvik cache, system like 50 times, i flashed another roms, the problem still exists. Sometimes i can't even get through the boot, it just shuts down.
I even tried to downgrade to a kitkat firmware, and return to imperium rom still the same problem encountered.
I really don't know the problem, i can access download and recovery menus, i can flash with odin, but can't get the phone to work normally.
Has anyone had the same problem? I'm starting to think that the motherboard is bricked, but why is it so random?
Thanks for your responses.
Best regards.
Check all cables
I got the same Problem , so i checked my motherboard and ive Seen that a cable wasnt putted on

Strange scenario, i changed the motherboard, still the same problem, removed the sd card, same problem, sim too, same problem, so i guess this comes from the battery
Hello everyone,
So here's my story: I got a 6P short after release and it's been amazing. After switching from a S6 I couldn't be happier until 3 days ago.
I was playing around with my phone (checking for updates on the play store if I recall correctly) and I was going to switch from 4g to wifi. I went ahead and pulled down my notification shade and went to press WiFi but misclicked and hit Hotspot which was below it. My phone suddenly froze big time and this is for the first time ever since purchase.
At first I thought I'd wait it out since the device was completely unresponsive, home button didn't work and neither did anything on screen. Buttons didn't make a difference either. 10 minutes went by and I ended up force restarting by holding down power + volume up. First part of my bootup went fine but when it got to the android boot animation after I put in my pin to allow the device to start it dropped from the smooth usual framerate down to 1 frame every 10-15 seconds and it slowed down further until it came to a complete halt around the time the android letters appear.
My first thought was corrupt rom so I went ahead and wiped data from the stock recovery. I was running completely stock with no modifications whatsoever. That didn't do anything. Phone still froze in the same boot phase. Desperate I unlocked bootloader to flash a clean fresh image to try to fix it and to my surprise that didn't change a thing.
As I was getting pretty desperate already I had one more idea and that was to flash up to the Dev preview. To my huge surprise it booted and I jumped from excitement. So I started setting up my phone again. I got past the prompt to insert sim card and I was now at the screen to choose a wifi network. As soon as I clicked into that the phone froze up again and at that point I lost all hope.
I wiped data in stock recovery and shut the phone down for the night. On day 3, today I woke up and tried starting the phone and it worked as if nothing had happened. I went through the setup and set up my phone on the N preview. At a certain point I was planning to go back to the latest official build but for now I was happy my phone was back from the dead. Later today I tried to restart my phone to clear all running apps etc and it froze up on boot.
I'm losing all hope that I'll be resolving this myself so I'm reaching out to the community to see if anyone's had this happen to them before and hopefuly for a solution. It's still under warranty so I can eventually send it back to the retailer but I'd rather not have a phone for 3 weeks.
Any and all help is appreciated.
Thank you for reading through my long and probably pretty boring story!
Have you tried flashing the factory image? If yes, did you made sure to wipe/erase the system, boot, vendor, and cache partition before flash the corresponding img files?
To the OP, is there any reason you did not flash to release version 6 instead of Dev preview ?
Also, any reason you can not simply do the "unenroll" from https://www.google.com/android/beta ?
It will require you to setup certain settings again as you will be back to a "factory reset".

DJBhardwaj, i haven't specifically erased those partitions. I was under the impression wipe userdata along with reflashing did that. I will try that tonight when I get home!
Xdafly, I only updated up to N as a last resort because at first I had a locked BL. I was planning to unenrol but that would've been too late as it self bricked after a restart.

Well I just did the erase thingy and my phone booted but wifi won't turn on. Enabling hotspot doesn't brick anymore but I now suspect WiFi might've been the issue. Any tips on how to find out what it could be and possibly fix it?
Edit: 2 restarts and a factory reset later I'm back to bricked same way as before.
try safe mode

That was my first thought, that was the restart that bricked it again. Safe mode shouldn't have made a difference since I hadn't even logged into Google account for apps.
After reading the very first post; sounds like bad WiFi hardware.
All the hanging has been related to WiFi or Hotspot.
I think you should get a replacement

Is your phone rooted and did you install Xposed?
Over the weekend I shutdown my 6p (stock rooted with April security patch, Xposed v80) and charged it. When it turned it back up I kept getting "Unfortunately, nfc service has stopped". Long story short: I ended up factory reset my phone and reinstalled EVERYTHING and I still got into bootloop. Then I came across
https://github.com/rovo89/Xposed/issues/113
https://github.com/rovo89/android_art/issues/28
At the end of the second post rovo89 (developer of Xposed) fixed the bug in V83. I wiped my 6p once more and installed everything with v83. Problem solved.
Good luck!
Classic "my phone keeps freezing and rebooting". I am quite in the know about flashing roms and such.
It started on the stock firmware 6.1.1 (i think it was). I dd factory resets, cache wipes the lot. It would still randomly reboot.
So i flashed Telstra version of 7.0. Still froze every now and then. Did the same things as above.
Flashed TWRP and wiped everything, flashed Renovate Rom and the bootloader for it, Still did it. Numerus factory resets and wipes of everything. It would freeze at any point from startup, to having setup the phone and making phone calls or on facebook or whatever. It would even freeze in twrp, or loading twrp.
I found that the data partition was corrupt so i re partitioned to ext4. Still nothing. I reformatted every partition so the phone was a complete brick with nothing on it and after flashing clean again it would still do it.
Whats the issue that I'm missing, or is there a way to log so i can find where it keeps getting stuck? It gets hot and blue light flashes and i have to hard reset it or sometimes i have to let the battery drain so i can turn it back on again.
pls help?
Hmm i will give you an advice so you dont have to wait for your battery to drain...just press volume down and power button for like 5 secs and phone will force boot. Anyway back to your problem...did you tried flashing latest stock samsung firmware?

This advice doesn't work with my phone even with holding the buttons for 30 secs and more. For rebooting I can only wait until the battery is completely drained. With little hope for another way shortening time to the next reboot any help is appreciated.
Same here...experiencing the same prob...
Same problem.

Sounds like you need your motherboard replaced i had the same issues on marshmallow thought the nougat update would fix it but realized it was a hardware fault not software..left it in store to get fixed and on repair sheet it said faulty motherboard..

As i know some S7 have motherboard hardware problem, mine has too, what help? warranty and they replaced motherboard. But if you root, you can say good bye to warranty, they look at knox first with this problem.
Hi all,
My wife's S7 Edge (SM-G935F) was updated a couple of days ago, and now the phone constantly reboots (not sure if related).
I have tried factory resetting, wiping cache in recovery, and still the same thing. I have managed to get it to turn on, but it still reboots shortly after. Mostly it doesn't even start, just goes into boot-loop
Not rooted, and in great condition.
Any ideas what to try?
Thanks

Have you tried booting into safe mode?
It's strange that an update would cause this however you could try flashing the update manually again or downgrading to what it had before using Odin

Thanks, yes tried safe mode, still the reboots... Ill maybe try flashing like you suggest

Install Smart Switch on PC.
Connect to PC and perform recovery install.
Still no luck , return your phone to Samsung service center for repair under warranty.

Unfortunately Smart Switch said unable to do on my phone
I do have insurance, but it's the last time I can claim for a year, and it costs the excess, or I have to wait several weeks if I send to Samsung
Any other ideas?

Even on emergency recovery mode?
If not, I would call Samsung and/or you carrier tech support and see if they have any suggestions.

Same issue right here, i tried almost everything... Flashed the new BRO firmware, and i still getting random resets.
i can't even get pass the first Google config in safe mode.
Same problem. Constant re-booting. Impossible to unlock, as no keyboard appears with the unlock screen. Impossible to turn off.
Try to downgrade firmware using odin to stock marshmallow , but first remember to have usb debugging checked in developer options , if they can't be accessed, the only option remains is smart switch , if that too couldn't help , then send it back for repairs.
have also got the same problem since the last OTA update from Samsung. My current version is G935FXXU1DQD7. I'm just downloading the later version DQHF to see if that resolves the issue.
A short term fix is to delete the cache from the system menu (when powering on with power button, home button and volume up button). It sometimes takes me 3 attempts to get into this menu to do the cache delete. After I have deleted the cache I can use the phone again, but it sometimes crashes and starts the boot loop when using certain apps.
I had this once even after fresh flash.
I deleted the cache when booting up.
Then factory reset when booting up..
Then when done i could flash it and solved it for me.
