hello,
i hope anyone of you can help me, i dont know what to do :/
yesterday I was at a party and dancing, it was very hot there, and as I took pictures, the phone was very slow. That wasnt normal.
So I put the phone back in my trouser pocket, and some time later, I realised that the phone was shutting down, booting, shutting down... in an endless loop.
I tried a different battery, putting the battery in and out several times, putting the phone to the loading station ..nothing worked.
I cant start the phone anymore.
I know that "normal" bootloop issues (after rooting or flashing custom firmwares) were normally solved by flashing the stockrom again, but I really dont want to loose all my data!
so is there any option for me, instead of deleting everything and flash the rom again?
( I have a rooted Note4, but with the original 5.1.1. firmware. Its a german phone.)
If any of you has any ideas that I could try, I would be thankful.

Hi folks.
So after a sleepless night and a lot of guessing and clicking around with no luck, I finally decided to ask for help.
The story:
Yesterday, I decided to open up my lovely N4 to perform the thermal pad mod (that can be found on these forums), as it was going really hot around the CPU at time and it seemed like a good solution.
Now, I'm no stranger to disassembling microelectronics without breaking them (few weeks ago, I successfully resoldered a broken power button in my old T989 that I've been using before N4).
What couldn't let me sleep at night:
And here is where the problem emerged. After re-assembling my sweet little phone (yes, i did it perfectly right), I tried to boot up and all i could see was an endless and really annoying bootloop, but as the device booted up, I did not worry much. While doing some research, I read that there's people experiencing bootloops with 4.3, so I thought that after disconnecting the battery, it just might've had happened on its own (I was using stock 4.3 with faux kernel before the nightmare started)
At this point, I booted into recovery and tried to flash the rom over, but unfortunately nothing positive happened. Then I tried factory reset and flashing different roms, also with no luck. This is when things started to get really frustrating, as no matter what I flashed, the bootloop was (and is) still there. But then I tries to restore a backup that I did right after getting my N4, back in November, and it WORKED. Why do i still have a problem then? Because it was 4.1 and OTA was giving me error every time I wanted to flash the update, so I kept flashing till i get some results. And then one of the N4 toolkits wiped my entire internal memory and I ended up with only being able to use sideload. Then I tried ALL of the N4 toolkits that can be found in here, to wipe everything and bring my phone back to everything stock, but the bootloader is locked so it cant do it, and it cant unlock it because I cant boot into the system.
Conclusion:
The phone works fine, and it proved it. But no matter what I try to flash (other than the old backup), the persistent bootloop is still there smiling at me like an a****le.
Any ideas?
Hi,
I appear to have gotten my phone into a bootloop. Nothing I did should have caused this. It was working perfectly when I went to sleep last night and when I woke up the battery was really hot and it kept restarting. It boots to the lockscreen (note: not a black screen, i can see my homescreen), vibrates a couple times then restarts. I have tried safe mode which does not fix, reflashing my rom, wiping cache/dalvik, booting with simcard and sdcard out... I would love to avoid wiping data if possible (and I'm not even sure if that would help at this point). Is this a hardware issue?
I believe you did all you can possibily do. the last choice is to Odin back to stock. you will have to either stick with the bootloop or lose your data but save your phone. by the way, no one can really help you unless you tell us your phone's firmware version and you have to tell us whether your phone is canadian or ATT or whatever...
It sounds melodramatic but maybe someone else has encountered the same problem and can help.
I got my phone last week and used it for a couple hours before I decided to root and flash a custom ROM onto the phone. I didn't realize that the kernel had dmverity and proceeded to try and root my phone like any other phone.
I followed the usual steps in installing root for the first time. I used Odin to flash twrp onto the phone and proceeded to restart into recovery. I had forgotten to copy supersu to my phone before I restarted it and this is where my problems began. I swiped on the twrp page where it warns of dmverity but because I didn't transfer supersu I had to restart the phone and get it on. The problem being the phone was now stuck in a bootloop and I somehow managed to get supersu onto the memory and flashed it. I was able to boot into the rom but it was extremely unstable. I could work for maybe 5 minutes before the phone froze, got very hot, then shut down. It would go into a bootloop and succeed maybe 1/20 times, all the while the phone got very hot. I flashed a custom rom onto it and it kind of worked but would still freeze and restart every once in a while. I found the stock bootloader, rom, cp, csc, and flashed those. My phone is now stock everything but the crashes still occur frequently (basically every time I try to use it) and I'm at a total loss as to what to do.
I've rooted all of my phones since I got my S3 several years ago and I've never had a problem like this. Anyone know how I can fix this? My phone is model G935w8 so I know it has the exynos processor and rooting is possible, but I must've done something horribly wrong for it to be like this. Any help is appreciated.
Alright so a while back I created a post here about some problems I was having with the stock rom I was running back then. Got some answers (thanks btw) and after some more problems I finally was able to flash Alexndr rom, but the problems were still there (random reboots, battery was draining hard and died at 25%, slow). I was told that the reason for these problems were that I didn't install a different bootloader, which was mandatory. I have been busy the past few days so didn't really have any time. But this morning my phone suddenly had a random reboot and weirdly, when it rebooted a factory reset was done. So I decided that it was time to install the new BL, but ended up flashing the wrong one so got into a bootloop. Then i flashed it again with the right BL, first it seemed like there was no bootloop because i got into the regular screen (choosing language etc.) but suddenly it started rebooted, and it didn't stop. It always gets to the language screen, sometimes to the wifi screen but after that it still reboots. Because i really needed my phone to work i flashed the stock rom again, also a bootloop.
So i hope you guys have any ideas how to fix this, because i have no clue what to do. And i really need my phone because my sister is in the hospital and i need to be able to get calls.
Thanks in advance.
This is the stock ROM btw: N910FXXS1DPC2 (German, android 6)
AND BUMP!!
Really in need for some answers
Long story short, I'm trying to find a job. I am at my wits end with this phone and can't afford a new one. If anyone can PLEEEAASSE help me, you will literally be saving my life. Galaxy S5 G900V. I woke up one morning (2 months ago) and the phone was mysteriously off. I tried to start it but it bootlooped. I gave it up for dead, but turned in on the next day for giggles. It started up. Worked perfectly. Thought all was well.
Then mysteriously did it again. After re-partitioning and flashing the lastest Marshmallow QI2 firmware with Odin, it bootlooped for a day. I shut it off, let it sit, and then it worked again the next day. I did a full factory reset all was good for 3 weeks. Then it started bootlooping again.
The only thing that I've been able to flash that gets past bootloop is PB1 version of Lollipop. Which goes into recovery mode fine. I can wipe the cache etc. It boots up. But it runs VERY slow even after doing factory reset. (At least it makes calls.)
Next thing I tried was Over The Air update back to QI2 "Marshmallow". That started the bootloop issue again.
I flashed PB1 back. No bootloop. But slow performance.
Most of the threads mention things like "Safestrap" and "TWRP" but don't explain what they are or how to do it...
Can anyone please please please tell me, how to get to square 1, factory stock status? Or direct me to instructions/files to fix this issue?
