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
Hello! Okay so this is a weird issue with my phone. It started in November and i had to switch to an older galaxy s5 which is pretty slow for today's standards. Anyways one day while it was charging it started to reboot and didn't stop. I didn't think much of it. I took the phone apart to make sure it wasn't shorting out or anything. I reset everything on the phone. I replace about half the phone. I really need the phone to work because I need the speed. So the full problem the phone would turn on and boot but right when it going to the lock screen it would restart. Sometimes it boots all the way but it crashes and reboots about 1 minute of use. I cannot find a solution. I tried flashing a the original rom and it still didn't work. I put the boot loader back to stock. I tried to reflash the kernel, that also didn't work. If watched a ton of tutorials but no one seems to have the same problem.
Hello, so i've had this Note 4 for about 2 years, i had no problems with it thus far until recently ( 3 hours ago actually) i was just texting and browsing Instagram and out of no where the screen froze, it became unresponsive and the screen went black and started constantly vibrating so i quickly pulled the battery out and put it back in again, tried to start it again and it got stuck on the Samsung logo, i went for recovery mode and tried to look up latest cashe log and it froze right there too and restarted, pulled battery out and in again, tried to get into Recovery mode for a second time and a dm-verity verification failed error on the lower left corner popped up, i selected "Restart phone" and it got stuck on the Samsung logo again, battery in-out, tried to get into Recovery mode for a third time to do a factory reset but this time it got stuck whilst trying to boot onto recovery, and i had to out-in battery again, tried several times to get into recovery and it didn't work, i just gave up and started searching, then after 14 minutes i decide to give it another try and it normally booted up! i inserted in my PIN and browsed the apps for about 2mins but it froze, again, and the whole cycle kept repeating i let it cool down for 15mins and it boots up normally but freezes again after a few minutes of usage, i noticed that it insanely overheats before freezing (especially right above the SIM card area) and the four CPU cores are showing 2469MHz and on 100% (But that's also the case when the phone just boots up right?), Now i basically can't access recovery mode and i'm stuck with a Freeze-Reboot looped and i'm left with no other option but a full Stock ROM flash, the thing is i can't even get into recovery to do a full wipe before flashing in the ROM, can i just flash in again a TWRP recovery? and is there any way to fix this without having to do a full Stock ROM flash (i Tried the wake lock app it didn't work) and i'm on Android 5.0.1, this has JUST happened today and never before. i'm hoping this isn't a hardware issue.
UPDATE: i have just noticed something rather interesting, the phone immediately freezes and goes nuts with the reboots and failed recovery modes instantly after i connect it to a wifi network, and exactly when it's attempting to "send report", a sending report sign shows up in the notification bar and it immediately screws up the phone until i do another Factory reset, i just did another one without connecting to a wifi network and i've already gone 40mins with it without any issues but perhaps it's just because it's not on heavy usage?
Sounds like you have the eMMC issue.
You can try and reflash with Odin. Get the right version from Sammobile.
Do yu get to download mode in any of the scenarios you describe?
Try WakeLock again and select the level to 4

If you have the Snapdragon version - it's highly possible to have the emmc problem. Which is a bummer and the phone is like dead.
Unless you can buy another 910C motherboard and swap it.
Sorry.
What is short name for emmc?

Just been having a very similar problem. I posted this elsewhere, but it may be helpful:
"My issue was that I needed to recover data, docs, photos, phone numbers etc. When boot looping the note 4 got very hot . In particular around and to the left of the camera (looking at the rear). Thinking it could possibly be the dreaded eMMC problem which also manifests itself by creating heat, I thought cooling the device might help. I placed the Note on a cooler box freezing block and voilà! No boot loop. I was able to remove all, but necessary apps and do a full copy to my PC. Storage was reduced from around 90% to 50% and memory 80% to 60%. It's now been stable for 12 hours, but the jury is still out. Next will be full reset with he latest available firmware 6.0.1 as mine was still on 5.1.1."
Also now downloaded a eMMC bug check that says my eMMC chip is 'sane'. Guess we'll see
This is a Nexus 6P (32GB) I rooted shortly after getting it (new) in September 2016, and updated to stock 7.1.2 in August 2017, but I otherwise haven't modified it from its out-of-the-box state.
Until recently, I'd never experienced any issues - no random reboots, battery was still pretty good, etc. Then last week, the phone rebooted suddenly, and appeared to "boot loop". I hadn't yet heard about the issues the 6P has with this so I powered it down, left it alone for a while, then turned it back on later, booted without incident, and forgot about it.
Last night it happened again, at which point I searched and learned of the dreaded "boot loop of death" the 6P specifically has had issues with. Hoping that wasn't the issue, I again powered down and tried it this morning, and it only stayed awake for about 5 minutes before going into boot loop. At this point I looked up and applied the fix described in this thread, but to my dismay it had no (visible) effect - I still see the initial "bootloader is unlocked" screen, then the google + open lock icon, repeat ad nauseum.
About all I can do with the phone right now is load into fastboot. The phone has data on it I'd really like to recover, is there a way I can do that from there? If not, is there any way to connect with ADB without getting through a full boot? Are there alternative boot loop fixes, alternative steps to the fix described? I've read several threads here and can't tell if any apply to me, and can't find any answers to the above.
I've accepted that the phone is probably never going to be the same again but I need to get my data off there and do a few quick things before I consign this one to paperweight duty. Thanks in advance

I have the exact same issue. I run the same version operating system as you have an unlocked bootloader otherwise have not modified the typical system install. I did already have the fix applied from an earlier incident but now it is boot looping and won't stop. I have red threads here and there that have advised to apply heat to the phone and that might get it to boot at least to get your data off. Myself I have had no such luck with this technique but perhaps it will work for you otherwise I have since moved on to the OnePlus 6t. A very awesome replacement not to mention at a decent price for more horsepower and storage

Just in case it helps anyone with this phone and issue, I was able to get a couple more boots out of it, enough to rescue some data, by doing the "15 minutes in the freezer in a ziploc bag" trick.
RIP Nexus 6P, shame about the BLOD!
it has been giving me small issues like wifi not wanting to connect, radio app missing all numbers on startup and volume taking forever to respond on first boot. Ive had this unit a couple of years and contacted eonon support for answers. They led me to download update.zip and update the unit with it. I attempted it yesterday and it loaded the update about 75% and paused for a few minutes. It finally completed relativly quickly and rebooted...It hung on the android screen(loading) for 15 mins and rebooted...same hangup then it shut down and wouldnt restart. folks...I think I killed it. It did try to start the next morning but with the same hangup-reboot-hangup-shutdown rince repeat game. any advice on it its saveable let me know please I have no idea how to enter recovery mode on this unit but i can reboot it while its trying to unsuck-sessfully load android...lol
Pull the power completely from the device, by pulling the fuse or pulling the ground from the battery. Just for some seconds.... and remove the update sd card/USB
