So I've reached out to this forum as I've tried a million and one things but can't seem to get my phone to boot.
Here's the situation:
I fell asleep watching a video on my phone and my phone died. I plugged it into the charger and it wouldn't boot, would just endlessly be stuck in a boot loop. Looked it up and saw this is a common issue. Went through the standard fixes:
Wiped the cache
Factory reset the phone.
Attempted to boot in safe mode. (Wouldn't work, still boot looped)
After all this failed I thought I would just flash it using Odin v3.14. T-Mobile is my carrier and I'm based in the US so I used this firmware: SM-N950U TMB, LINK(https://updato.com/download-samsung...sa/sm-n950u/B094B9DAF04A11EAB4A2FA163EE8F90B/)
It still didn't work after this. It booted up and the startup process began asking me to agree to the terms and conditions. Before even getting to agree, the phone crashed. I tried this again and it just kept failing and crashing. I did this all while plugged into a charger. What I did begin to notice is that the phone would get hot on the left side, where the battery sits. I'm not sure if this is related to the crash or just the fact that its been discharging and charging a lot while I troubleshoot it. I have tried different firmware as well just in case I had the wrong one, but nothing has been working. When I update the firmware I used the CSC file and not the HOME_CSC and I also use the USERDATA file since at this point I kind of accepted I'm not getting my pictures and files back and I'm just trying to get the phone to work once again, thus just trying to factory restore it. Also, when the phone does start booting it says optimizing apps on the bottom each time I boot it I feel this number is changing. I'm not sure what else to do or if anyone has any suggestions? Thank you in advance

My friend is having some problems charging his Atrix. Basically, the phone will not charge or recognize a charger at all except for under certain circumstances.
Some background info: I helped him unlock his bootloader and install 4.5.91 way back when it came out. No problems there, it went well. All was fine until the 4.5.141 OTA update came around. He got the OTA notification and clicked update because he didn't know anything bad would happen. Luckily it didn't brick him like it did a lot of people, but he said it gave him an error message during the install and it would not boot after that, stuck at the Motorola dual core screen. I took a look at it and managed to get into recovery and flash back to 4.5.91. All was fine until it was time to charge the phone. It wouldn't recognize any charger. I tried flashing to tons of different roms, wiping everything, even restored a full nandroid recovery from my working Atrix on it. His phone will charge and will be recognized by a computer immediately after we flash a new rom, and will continue to charge for as long as we leave it plugged in, but if we unplug it then after a short time (like under 30 mins) it will not recognize a charger if we plug it in again. Wiping data alone will not make it start charging again, only actually installing a new rom will. Deleting battery stats does nothing. The closest we have gotten to fixing it was when I made a nandroid on my Atrix and then restored it on his (my backup was from Joker's CM9); after the restore, it would charge for a while, and we unplugged it and waited to see if it would do the same thing as it always did and stop recognizing a charger after a few minutes. About 30 minutes later it stopped recognizing the charger as usual. We played with the USB debugging setting (enable, plug in, see if it recognized the charger, disable, plug in, see if it recognized it, etc) and after messing with that setting a lot it recognized the charger once, but then when we unplugged it the phone wouldn't recognize the charger again. We could not reproduce this again.
To summarize what we have tried and found to work:
-flashing a rom will let the phone charge/let a computer recognize it for as long as we leave it plugged in after the first boot (we have tried every rom under the sun, they all do the same thing)
-restoring from a nandroid backup will have the same effect as flashing a rom
What we have tried that didn't work:
-different cords; have tried them all, both OEM cord and third party, this is not the problem
-wiping all data/factory reset doesn't do anything
-cache wipe doesn't do anything
-wiping battery stats doesn't do anything
I have also tried fastboot flashing back to 4.5.91, CWMing back to 4.5.91, using the unbrick scripts and stock restore scripts people have made, nothing will fix it.
If anyone has any suggestions or can refer me to anywhere with more info on this I would appreciate it, I have searched high and low and can't find anyone with a problem quite like this one. I don't even know if it's a hardware or software problem, if you guys know a way to determine this it would be helpful.
Have you tried a wall charger?
Yeah, both the stock one and a different one I have, neither work.
No one has any advice or ideas on this? Does anyone know if Moto does repairs in this type of situation with a voided warranty because of an unlocked bootloader, or does anyone know who may be able to fix this if I can't get any help from the forums or figure it out on my own?
hello everyone, my stock s6 edge on rogers is stuck in a boot loop all of a sudden, fully stock and unmodded, running 5.0.2. i was just walking and listening to music through bluetooth headphones and all of a sudden it stopped, and i looked at my phone and it was rebooting. so i just waited and its still stuck in a boot loop after an hour. it gets to the lock screen sometimes, and then after like a second or 2 just reboots again. i have not tinkered or have done anything to my phone either, and had no issues with random reboots ever, so i have no idea what could have happened
some extra info, when it reboots it doesnt always go to the galaxy s6 edge screen, it sometimes just shows the samsung logo with the animation. i have also tried to wipe cache and that didnt work either. after a few reboots however the stock theme was applied at some point. also i tried booting into safe mode and that also didnt work.
i really dont want to wipe my phone, but i will if it is absolutely necessary. so if anyone has any other suggestions that i can try out it will be very much appreciated!
thanks!

I have had said problem before under the same circumstances (although it was with a different phone)
Try using Odin to install the stock Firmware.
A thread explaining how is right here.
http://forum.xda-developers.com/galaxy-s6-edge/general/sm-g925f-s6-firmware-thread-t3078841
If you don't want the firmware listed in that thread, download from Sammobile.
While some users say it does not wipe the phone, it wipes every time I use it
If this does not work, you should get a warranty replacement.

Thank you for the reply!
weird thing is it fixed itself .. few hours after it started it just booted back up and didnt reboot again, and has been running fine for the past couple hours. but if this happens again i will know what to try next time
Long story short, stock phone just randomly blew up and I'm trying to re-install its stock Android OS. Phone has never been rooted before, it just started to reboot on its own and now I'm in a position where I can only access download mode.
I'm in Odin, with what I believe is the correct firmware for my device (SM-N950U1) and I just keep getting a "Secure Check Fail: system" when trying to flash. it via Odin. The Odin log says "FAIL! (auth) right after trying to write system.img.ext4 for a few minutes. The "Secure Check Fail: system" is the printout on the phone screen itself.
Any clues?
Bump! Anyone?

I see that you have not received an answer. That is upsetting. I am also struggling with this exact same issue on a g955u1. Have not found a solution. Did you end up solving your problem? If so, what did you have to do?

Nope, I have not solved the problem. I've scoured the internet and other people asking the problem all have not had any answers either. My assumption is that the actual internal memory of the phone is corrupted and won't let me write past a certain point, or on certain sectors, or something and its not actually fixable via software. I think everyone else just stops at this point and its never resolved because there is no resolution hah.
Good luck, let me know if you ever figure it out...

This phone I am working on is for a customer of mine. Thankfully, they have given me an open ended time frame. I have been working on this for about a week trying to figure out whats going on.
The memory corruption thing you were talking about resonates with me, because prior to my customer bringing this in, they had attempted a couple factory resets trying to resolve the original issue which was all the system apps crashing. The phone would reboot like someone killed all the processes. Pretty much from the moment it reached the home screen, and it was not power related. The problem persisted after their factory resets within recovery mode. And then I hit the phone with Odin and ended up with a partial flash. Soft bricking the phone.
You saying that kinda reinforces what I was already thinking, that it might be a hardware issue. Im not sure.
5 minutes ago I was able to get odin to successfully flash BL, CP, and CSC. It even brought me back to the Samsung logo for a minute but hung there. That's the most success I have had with this thing. Ive flashed numerous firmwares and every single one of them fails on system.img.ext4. After it reboots, it boots directly into this altered version of download mode with an emergency recovery error.
I have flashed dozens of phones before without issue. This is the first time I have ever experienced this one. You could be right but I refuse to accept defeat in this case lol so im gonna keep trying and ill report back if I have success.

Man, that sounds very very familiar to mine. I don't know if you found my other threads where I was asking for help, but I woke up with a phone that wouldn't turn on. Finally found the key button combo to get it to soft reboot, then it would turn on and just crash in the middle of using it after anywhere from 30 seconds to 5 minutes. If i started to use the phone heavily it would just shut off instantly and reboot back up on its own.
After clearing the boot cache, then doing a factory reset, it finally just stopped turning on at all (just samsung boot logo loop)
So I hit it with odin, unsuccessfully for 2-3 days, and then out of nowhere it just finally took a successful flash. However, it still just bootlooped, so I did a factory reset again and it put it back to being toast.
Since then, not a single successful complete flash from odin. I too can do the BL, CSC and CP files but I can't flash the AP file as it is writing the most data and finally fails about 3-4 minutes into to writing the system image file.
Again...good luck, ha!
Hey, so I woke up today to my phone at a recovery screen (I'm not very familiar with any of this stuff) and it said to reboot, so I did. Since then, it has been stuck in a never ending loop of restarting. I was able to turn the phone completely off, but since starting to tinker in it within the past few hours it won't stay off. Currently I am at some screen where I attempted to follow this video to load some firmware, but I couldn't find the firmware I needed to download as I have no clue what model number or current software version I need. Is this the right step to take to get access back into my phone? I just wanted to save some of my pictures and videos that I don't have saved elsewhere and then factory reset my phone. basically, I've only felt comfortable clearing the cache partition to see if that would work. My problems seem almost the exact same as this thread on this forum. Any help is greatly appreciated. Is there any way to access these files? I looked it up and it said to use Samsung Smart Switch, but I didn't have that on my phone and there is not enough time I have in my phone to download or uninstall any app before it enters the restart loop.
Hello XDA community,
I have a G965F that is permanently stuck on the first boot screen (Samsung Galaxy S9+ secured by Knox powered by Android) and it will not progress past this point. I have left it on for hours, and it just stays on that screen. Recovery mode does not work; if I try the button combination for it, it just stays on the same screen as mentioned before. However, I am able to get it into download mode. From here, I have tried flashing every firmware I possibly could, of course with the correct region and version, but nothing works, and the situation stays the same as mentioned before. Odin usually finishes up with no problems and reboots the phone, in which case the bootloop happens once again. On the rare occasion that Odin does fail, it will not boot even to the first splash screen but rather to the blue screen with the triangle, telling me to connect it to SmartSwitch and go from there. I have attempted this also, but SmartSwitch only gives some errors, and it fails.
The phone was on the stock firmware for a few years and even updated through Odin when OTA didn't work. It is a UK-unlocked Exynos device. About 2 years ago, I decided to switch to lineageOS using Neuroticals ROM, and that worked flawlessly, OTA updates and everything, 0 problems. I even went back to stock at some point and reinstalled Lineage shortly after because of how much it improved the device. About 9 months since I last did any type of flashing, the phone randomly froze while I was using it (I think the bottom half of the screen went black) and was totally unresponsive until I forced shut it down. This is where the aforementioned problem began.
I thought letting the battery run out would help, but it hasn't. One thing I have noticed is that it either charges very slowly or doesn't at all; it will only stay on for a maximum of a minute after it is unplugged. I left it for a few months, hoping to discharge it completely, but the problem persists.
Apologies for the lengthy post; I've used this site for about a decade for mods on various devices and it has solved all of my problems, but this is the first one that has really stumped me. For the past few months I've spent tens of hours searching various forums and webpages but can find very little about my specific problem. Thank you for any help in advance.
I will include pictures of the codes that download mode shows, and hopefully someone has some answers.
PS. For some reason current binary says "Custom (0x8)" after successfully flashing the stock firmware many times with Odin, but when Odin does fail it will show "Samsung Official". This I cant make heads or tails of.
