[Galaxy Note5 Q&A, Help & Troubleshooting] maskimmortalsucks:
Hello! My Galaxy note 5 (SM-920G) has been stuck on a boot loop for a week now, I've tried everything. I've used "wipe cache partition", "Wipe data/factory reset", even flashed stock firmware from sammobile using odin. I'm still stuck on a bootloop. I am gonna proceed to explain the events that occurred before and after the bootloop in a level of detail that I'm capable of, also one that I think should be sufficient.

Events before the bootloop:

So here's what happened. I was using my phone as usual when I noticed that I couldn't play any music. Spotify, which I was using at the time, refused to play any song. So, I checked out Phonograph(music app that uses local library) and I couldn't seem to play anything from my local library either. I then proceeded to go ahead and open YouTube only to realize that I couldn't play a video on YouTube either. After much fiddling (I don't remember what exactly I did that caused it) but a YouTube video played, but I heard no sound. From here on out, I could PLAY/VIEW any media related file and such but I heard no sound. I searched it up and apparently a cache partition wipe seemed to do the trick (I should have dug deeper into this but this is what I found). I proceeded to the recovery menu and selected "Wipe Cache Partition" (Forgive me, memories a little fuzzy from here on), If I recall correctly, I got into a bootloop and I wiped the cache partition again and it booted up fine. However, there was still no sound, since it was late at night I decided to give up and go ahead and sleep for now.

The next day, when I woke up, everything was working perfectly. I had no idea why.. but hey, I wasn't about to complain. Fast forward a few days, the sound issue popped up again, so I proceeded to wipe the cache partition again. I repeated this a few times but it didn't work, so I gave up. My phone was booting perfectly fine then. During the course of a week or so (maybe less) I had done quite a few cache partition wipes hoping that it would fix the sound issue. I also tried calling someone, only to figure out that person on the other end couldn't hear me and I couldn't hear them. So, one of these days when I did the whole cache partition wipe, my phone wouldn't boot up. This is where it got stuck in a bootloop.

Events before the bootloop:

So yeah, my phone was stuck in a bootloop. If I remember correctly I used the "cache partition wipe" a lot and even opted for the factory reset option. Which didn't work out either. I finally opted to flash stock rom today but over the course of some days I have been trying a combination of "cache partition" wipe and factory resets. Of course, my attempts were in vain. SO, I decided to flash stock rom today. I found the firmware I needed and used Odin to flash it on my phone and that didn't work either, still stuck on the bootloop. I tried a factory reset and cache wipe after the flash as well.

1- Screen I'm stuck on

2- When I go to recovery mode, first screen that pops up.

3- The so called update fails, second screen that pops up

4- and finally the recovery menu pops up

So yeah, that's it. I'm currently in the midst of my A level's, so my days are pretty hectic and stressful. I apologize for the long post, first time making a thread on XDA. Please help ;-;
