PROBLEM!!! my galaxy s6 is stuck in a boot loop. - Galaxy S6 Q&A, Help & Troubleshooting

i have not used my phone in any wrong way. i did not install a custom rom or anything. no root. randomly in my evedy day normal usage of my phone, it started to restart. and the the problem got worse and worse. for a few minutes, i will be able to use my phone but then my phone will restart and be stuck restarting. most of the times i cant even go into recovery mode. it restarts again when i get to that. i already reseted my phone, and i wiped the partition.
i have a samsung galaxy s6 SM-G920W8 telus/koodo 32 gb. i got the battery replaced by samsung but that didnt work. i noticed that after a few hours, my phone stops restarting when it reaches to 10% battery life.
WHAT DO I DO?? YOU GUYS ARE THE PHONE EXPERTS!!

You might want to try re-flashing the firmware. If that doesn't fix it, then you probably have a faulty device.

i tried reflashing but now i got "there has been an error updating the softawre. please use smart switch to recover" or something like that. and my phone is not supported by smart switch..... and when ever i try using odin, i always get NAND write error.i have a telus locked phone, 5.0.2 or 5.1.1 firmware. it is the latest odin and i have the drivers and i tried several solutions but that didnt help with the NAND write error.

Have you tried the original LATEST firmware from SamMobile? Using the original cable? The latest version of Odin?

latest telus/koodo version i can find for my galaxy s6 SM-G920w8 is 5.0.2. i only use my origional usb cable. i always get nand write error. my version is 3.10.7 of odin.
phone: SM-G920WZKATLS
locked to: telus/koodo
firmware: 5.0.2
i tried a 5.1.1 update too but that didnt work. i tried a rogers one but i still got nand write failure. on my s6, it says "
system rev. check fail device: 2 binary 1"

Ok...make sure you enable developer options...and enable OEM unlock....also go to security settings and make sure Reactivation lock is disabled or unchecked. ..then try flashing the firmware and it should go through just fine

i managed to flash a rogers firmware using the samfirm software but my phone is still restarting multiple times

My sister had a Galaxy S4 that would randomly reboot once in a while. Over time it became more frequent until it would barely finish booting before it would restart. Eventually it stopped turning on altogether.
Before it died completely, I tried different firmware versions and three different batteries and no change. I even took out the motherboard and put it in another S4 and it still wouldn't boot. Put the other S4's motherboard into the broken phone and it worked just fine. So it was something on the motherboard that died.
Sounds like a similar issue with your S6. Fact is, if a full wipe and firmware flash doesn't fix it, it's a hardware issue and there's nothing we can do.

Bricked galaxy s6

So I went to restart my rooted galaxy s6(pingpong root) and I ended up with a boot loop. Phone goes to black screen after the samsung logo and the blue light is solidly on. I was able to get into recovery, wipe the cache, factory restore, and it still failed to progress past boot screen followed by the black screen with blue led. It eventually started randomly one time out and I was able to set up the phone. Somehow I accidentally clicked the update to 5.1.1 and it went to restart and I think it said that the update failed presumably bc Im rooted and then went back into the same boot-loop only this time I cant no longer get to recovery. I used odin to flash my firmware (G920VVRU1AOE2) 5.0.2 as I have done successfully in the past and It went through all the steps successfully. When It went to restart the phone it continues to go to black screen with blue led. I tried 4 more times( all successful) to reflash the firmware with the same results. I can get to the screen before recovery with safe mode, pwr down, wipe data, etc. and all of the options produce the same results as above. I called verizon and acted completely oblivious and they are sending me a new phone but It still shows up as Custom with the unlocked icon on my boot screen. Does anyone have any ideas how to unbrick or relock the bootloader so I dont have to send my device in like this.
Also, when I plug in the phone my computer recognizes that a device is plugged in but it is not recognized and I cannot view the sd card, however it still connects to odin surprisingly
Sounds like you might have updated to of1 which there is not a 5.1.1 for a Verizon s6 by the way. If that was the case and it installed of1 firmware you will only be able to Odin of1 you won't be able to go back. Which leads me to believe why you are getting anywhere with the oe2 files.

Also try smart switch. It has recovery programs for if a phone is bricked.

The boot loop is leading me to believe there is a mismatch between stock rom and firmware, as MrWicked1 stated above. If you try re-flashing OE2 tar in the AP slot and OE2 firmware in the CSC slot of ODIN, you should be able to get back to the homescreen. Unless you mistakenly flashed OF1 as I did 2 weeks ago. I bricked my new phone today, after installing a wonky app, re-flashed the phone with OE2 and rooted. Afterwards, I deleted system/app/sdm.apk, system/app/securitylogagent.apk and system/priv-app/spdclient.apk to prevent the of1 OTA .
So should I try to OE2 first and if that doesn't work try flashing OF1 in the AP slot?
And of1 modem from of1, if oe2 doesn't work.
I got both the tar files for of1 and oe2, but the oe2 firmware file I downloaded is not an md5 its just a folder. Can you point me to the md5 for that. And where can I find the of1 modem file and where/how do I flash that in odin if need be.

Hi, do u solved it? had the same issue but cellphones was running 5.1.1

s6 restarting/freezing all the time

Hi,
i got my s6 about a month or two ago, became it from a friend so it was not new and it already had stock 6.0.1 installed.
It worked fine till a week ago or something, then it suddenly started freezing (till either the battery goes out, or i put it out manually with lower+power button) or directly restarting.
At first it happened about one time a day and i din't really wonder, it was rooted, had xposed, u know the instability...
But from day to day it became more frequent until it was about every 10 minutes.
so what troubleshooting have i done till now:
factory reset. It got better and less frequent, but it still happened. After about one day it was at the 10 Minute frequency back.
completely wiped it (twrp) flashed stock 6.0.1 w/ odin. Same result as factory reset
installed xtrestolite. Same result.
Looked if the Problem was a Hardware fault. tried stress testing the GPU the CPU and the RAM. None of these freezed/resarted the phone.
installed another Kernel. Same result
tried to flash stock 5.1.1 w/ odin. Odin gave me an sboot.bin error, excluded the sbin from rom. Odin gave me an CM.bin error., excluded Cm.bin from ROM. Odin gave me no Error, Phone bootlooped at Samsung Galaxy s6 screen.
Tried various variations of 5.1.1 and 6.01 stock roms mixed up. (CM.bin and sboot.bin from 6.0.1, rest from 5.1.1,...) always leading to either bootloop at Samsung screen or Phone force crashing.
I do believe it's a Software fault, as it does work normally for a day or something when factory reset, but as I tried about 1000 things, i'm not sure anymore.
By now I really don't have any more ideas but some questions:
Why can't i flash stock 5.1.1? I'm 100% sure i tried the right csc and BTU.
Is there any custom ROM i could try? The next thing i'll try is flashing CM13, just to try if it force crashes. If it does not it still sucks cos its unstable af.
Are there other non-touchwiz-based ROMs?
Biiig thanks in advance, any help is appreciated. :angel:
Edit: when I try to flash 5.1.1 it also gives me an error on the phone in Download Mode: SW REV. CHECK FAIL. DEVICE: 4 BINARY: 1
Anyone has an Idea what that means?
Edit2: Sometimes when it freezes, the red led is lighting (also till no battery or i manually put it out), By now i'm not sure if it just freezes too (already lighting when the freeze happens) or if it is additional to the freeze.

Yea man I would assume this is the only quick fix for this issue tbh.
I'm on cm13 and it's definitely gotta be an issue in Xposed hooks and power switches, because I've seen it happen with Kernel Auditor the cores just FLY thru the roof at bootup, full on max mode, then it reboots lol, and every single time, I was just done either
1; rebooting thru my xposed power menu,
2; rebooting thru the "reboot to system" option thru TWRP,
But man I got SeLinux Enforcing on an AOSP build right now, + other craziness, and my knox counter still tells me im on official binaries haha!
Hi guys,
I got exactly the same problem on an SM-G920F, i already try what @jaannnis do even re-partition on ODIN, im not rooted, not xposed all stock firmeware, i tried 7.0 and 6.0.1 over odin and over smart switch, that work for 12 hours and back to freeze every 10mn.
Im wondering its a batterie problem, or charging circuit issue...
Someone got a solution
Thx in advance

Samsung Galaxy Note Edge N915G, non rooted phone is stuck in boot loop!!!PLEASE HELP

Hello All,
This may seem like a regular problem but it's not.
I own a Galaxy note edge N915G - Indian model. not rooted even once.
This morning when I reset my phone and I was reinstalling the apps, my phone was working fine, but when I initialized WhatsApp my phone went into BOOTLOOP.
I tried installing the official latest firmware from sam mobile N915GXXU1DPK6_N915GODD1DPK3_INS for my phone using Odin 3.10.6.
Also, factory reset and cache cleared after flashing the stock rom,
But I still don't have any luck in clearing the boot loop.
As my phone is not rooted I don't know what else to do.
I tried with Odin 3.12.5 too. but no luck.
I also tried the firmware N915GXXU1DPK6_N915GODD1DPK3_INU from sam mobile but it is still stuck in the bootloop.
I can go in the recovery and the download mode but cannot get it fired up.
I have nowhere to go as the phone is out of warranty just this month.
Is there any other solution for this or something I have to do differently?
Please help me as I am out of my country now and I have no phone to use other than this.

Galaxy S6 - freezing and rebooting 50+ times a day

I've got a Vodafone UK version SM-G920F that has recently started to freeze, crash and reboot constantly.
I managed to back up my data and perform a factory reset from the Setting page, but it crashed 10+ times during the install process (would freeze at various different stages, either rebooting on its own, or requiring a Vol Down+Power reset)
I'm now on a fresh install, but it's still rebooting constantly. I managed to use it like normal for an hour today, but right now it's just rebooted 3 times and won't even get past the Samsung loading screen without several Vol Down+Power resets.
What other options do I have? And is anyone aware of a known hardware issue that could cause this?
I was considering flashing a different ROM, but I'm scared it would reboot during the process and corrupt something...

Maybe a battery issue?
a friend just gave me his very same model phone with the very same issues.. if I find out anything I'll tell you here, or if you solve it first please write down what you did.
Thanks Vibbuz.
I've been trying to download a stock firmware to flash via Odin, but download speeds from Updato are really bad.
So I managed to flash a firmware after installing Odin on a Windows laptop (painful trying to get it to work on my Mac)
Firmware installed OK, but after boot I was getting a constant "com.sec.epdg" pop-up box that wouldn't let me use the phone at all. Not sure if that's due to the tsar3000 firmware?
Wiped the cache and did a factory reset after booting into recovery, and now it's stuck in a boot-loop again (95% of the time it hangs at the Samsung logo animation)
Just tried using SamFirm v0.3.6 to find the correct file. Downloaded a 4gb file, but several attempts to extract only gives BL, CP, CSC files but no AP (throws up an Unknown Error during process).
So still stumped!
Yet another update. Left Updato running overnight and downloaded a firmware.
Flashed it with Odin, claims to have succeeded but phone then reboots and hangs at "Erasing" stage (Android logo is spinning, then stops)
I'm starting to think it's pretty broken...
I've been having this exact same issue since June. If your phone happens to boot try activating power saving mode (to reduce cpu speed) as soon as possible.
It seems that doing that diminished the frequency in which my phone rebooted. If it also helps you it might be a faulty battery that can't provide enough voltage. (I'm not 100% sure on this part though, just thought of it because of the apple batteries drama)
Please post your results! Looks like a lot of people are affected by this and it would be great if we could find the cause of the problem.
I just read your thread actually! Sounds very similar to mine.
I've got nowhere. I don't think it's hard-bricked as I can still access Odin mode on the phone, and sometimes boots to Recovery, but it freezes and various different points and is currently unusable (either freezes at Samsung logo, "Erasing" part after installing firmware, or once it started to run though new device setup then froze).
Went ahead and bought an S8, but still want to fix the S6!

Hi I have same Problem I send the my s6 for repairmen that Saied me this problem related to mobile Hard drive.
I didn't believe it and try some official rom and a rom from Philippine GLB solve my problem for 3 M/o but now developed as same problem whitout any successful rom installation.
I think this problem from incompatibility google play store version to my rom. please flash a custom rom without google apps and immediately after installation turned off data and Wi-Fi internet after 2 day whit sim card whit out any change in setting can use it.
Hello,
anyone found some kind of solution? Happened to me also - freezing, restarts and then my S6 stopped working.. Sometimes I can boot to recovery menu, sometimes it boots up to android (and then freezes again), but the chances are almost non existing. Service man told me the same thing as @ghasemzm - eMMC failure. Yes, it is completely possible, but i don't wanna believe it, because they only tried to reflash the rom. I've made some "google research" and found that there were some issues in power IC on S6/S6E. Could this be related to it?

Will test the theory and let the group know.
So i have installed philipines latest update 6.0.1 i think with PIT file provided on Sammobile.
I have tested it for a day with normal ussage like i set up every other phone and it still continued restarting.
Figured out let me test with no google account signed in and the phone is working perfectly. For a full day.
So i dont know what the problem is but i will try again with google account tomorrow for a day see what happens.
After that will install 7.0.1 uk update with PIT file for it and test with that.
I have the same problem and I am quite sure that it is the mobile hard drive.
I tried to use F2FS but didn't find a working rom for that.
Samsung refused repair because of root.... Never Samsung again!
same issues here - any solutions found? My best guess is hardware fault...

Possibly bricked galaxy tab A? flickering screen, won't flash anything

Hi all! I have been trying to fix this tablet for weeks. It's an SM-T580 Galaxy Tab A 10.1 tablet. It's actually my girlfriend's tablet and she tried to root it first and she royally screwed it up and I am having a lot of trouble cleaning it up.
So, when I got to it, she already had it stuck on the downloader mode and if you tried to boot it, it went to the blue screen that says "An error has occurred while updating the device software. Use the Emergency recovery function in the smart switch PC software."
So here is everything I did as well as I can remember it:
1. Tried every version of smart switch and KIES software. It does not recognize it ever.
2. Tried to flash custom recovery, but FRP lock is still enabled. She must not have correctly changed the settings in the tablet before beginning the root.
3. Tried to flash stock firmware, but it says it needs to be repartitioned. I downloaded what I thought was the pit file, and repartitioned the chip, but it still won't successfully boot. I tried several different cables and ports.
4. Tried to flash probably 10 different firmwares to see if anything would stick. Used several different versions of Odin all the way from 1.3 up to 13.5. Nothing will successfully boot.
5. Found stock recovery (I believe) and got stock recovery on there but when i get to recovery it says it can't mount anything. It gets a huge list of errors like "can't mount E..." I am able to ADB sideload, but so far nothing I try to sideload works because it says it has the wrong footer and the wrong signature.
Am I boned? She left it plugged in for like a week at least, so my assumption is the emmc chip burned out. Any and all help massively appreciated!
