Rooted phone bootlooping, clearing cache and factory reset not helping whatsoever. - Samsung Galaxy S5 Neo Questions & Answers

My phone is doing this weird bootloop where it loops 3-4 times, boots up, and starts looping again after 30 or so seconds. So I rooted my phone with Odin and CF Auto Root, and it worked fine. I tinkered around a bit, tried to get my games on my sd card with gl to sd and FolderMount [Root]. I had no success, so I uninstalled them. Everything was fine until then. When I tried to open one of my games(one I didn't tinker around with), I got a pop-up saying something like "reboot to recieve benefits", my phone resetted and started bootlooping. I have no idea what caused it. Everything was working fine until that moment. I've wiped cache, factory resetted(when it boots, I get an error saying the UI is disabled and it reboots). I can't afford Reiboot, and i'm going to try to flash stock firmware/ROM with Odin, but I don't know if it will help.

SBF'd yesterday, now it boot loops

So like the title says, I SBF'd my phone yesterday to start from scratch, and now the damn thing is boot looping. I was running LB .5 on .595, and flashed the VRZ_MB810_2.3.34_1FF_01.sbf file using RDLite 4.8 (same thing I've done before, just not while on GB).
I've tried SBF'ing it a few more times, and I've let it sit, trying to boot, for 20+ minutes. The SBF seems to go through successfully. The result says PASS, so then I reboot the phone, and then boot loop.
Anyone have any suggestions?
Well, nevermind...instead of doing those multiple SBF's, I should have just looked around. Found this on droidxforums.com, and it's going through the activation now.

You always need to wipe data and cache a few times before SBF'ing or installing any new ROM from scratch. Only with incremental upgrades to existing ROMs where the ROM chef says you don't have to wipe, can you avoid doing so.
Well, I didn't think I needed to specify, but yes, I wiped data/cache/dalvik when I flashed the ROM. So I don't really know why I then had to boot into stock recovery and do it again.
How many times did you wipe them? It doesn't work like deleting regular files on a computer, you need to clear them at least 3 times each. I don't know the details as to why, but never clear data/cache fewer than 3x. I do 5x.
weird.... mine usually works and on the pc just stops on 99% eventhough it's done and working. And once it bootlooped after installing a custom ropm and coudn't access both clockwork or original recovery so sometimes it may work, sometimes it may not work.

apps crash, phone reboots

I had been using rooted kitat for sometime. Everything was great. Then I installed a 5.0.2 Russian stock ROM and that ran fine too. But after a few weeks, I have been getting this problem. It seems the phone doesnt load apps and/or they keep crashing. The phone eventually hangs and reboots, and even gets stuck in a bootloop at times..I have tried flashing alternative roms through odin, i cleared the cache and wiped data through recovery but the problem persists...most of the apps that are glitching are google apps and sometimes systemui and phone....What else can I do?

im having the same problem on my G530H. does anybody know how to fix this???? its really annoying
Maybe you didn't factory reset before update to 5.0.2

ATT S5 Active (SM-G870A) bootloop issue...

The phone hasn't been rooted or otherwise tinkered with and is currently on android 5.0,.
Recently the phone has started boot-looping (never gets past the black S5-Active screen), though it strangely works fine while on the charger. This seems to have started when it tried to download an ota update from att a few days ago and the install failed.
I've tried using odin to flash it back to stock and start over, but odin seems to always fail, i can boot into stock recovery just fine and it will stay there once you get there.
Any help would be greatly appreciated.
Thanks in advance.
Tried clearing the caches from recovery?
yes, have cleared caches, and wiped data/Factory reset. neither seemed to have any effect.

[Android 8.1 Oreo] Random reboots in my second time install

I installed 8.1 last week. Everything was working smoothly. Was trying magisk youtube mod. Screwed something up. Phone went into bootloops. Reinstalled everything .Wiped data. Now my phone reboots randomly. Everything stock .Rooted with Magisk. Mainly it happens whenever i launch a new app(An app which was not launched before). After few tries, the app opens up and doesnt' result in reboot.
Any ideas what could it be ?
You should of wiped system and cache also might be your problem. Also if you where using any substratum themes remove then manually as well. Not sure if they would cause reboots.

FC's are one thing but random reboots are a completely different animal. I would completely wipe the phone and apply the latest factory image using flash-all.bat. If that doesn't fix it you may have a hardware issue (eg. degraded battery).
Wiping caches helped
I'm running SUPERXE-8.1.0-OPP5.005_v1.5.1.
My 6P was going crazy, restarting every 5 minutes or so. It rebooted so quickly it felt like a soft restart, so I thought powering off and rebooting to recovery using the power + down volume to clear the cache in TWRP would help.
Cleared system and Dalvik and powered down. Full reboot and (for now) it feels much happier and hasn't spontaneously restarted yet. That was about 15 hours ago.
Hope I didn't just Jynx myself, but I think it helped...
I've flashed the final 8.1 images to upgrade my 8.0 unmodified system. Now I've random reboots, usually when I've leave home to go to work or vice versa. Something related to wifi, that I'm connecto on both my work and home?
Same here I had to factory reset I'm having a feeling it's going to happen again. I am on factory, rooted with magisk. I always use SuperSU not saying that is what it is however it did happen when I got home from work and just kept rebooting before I could unlock.

XT907 bricked (probably partitions in read-only)

Good morning.
After almost 3 years with no problems with a XT907, I have again an issue with it (this time, my father's one). Again, I come to you requesting help.
It all started with all apps crashing over and over. With an old XT907 I have for emergencies, the common fix method is flashing VZW_XT907_4.4.2-KDA20.62-15.1_1FF.xml.zip with RSD Lite v6.1.5 and all solved.
I tried that method with my father unit, and when it started again, all process were still crashing. I thought it was still nothing (just a harder issue), and tried flashing VZW_XT907_4.4.2-KDA20.62-15.1_CFC_1FF_SVC.xml.zip, just deleting all his data, to fix it.
When the process ended, it turned on and it had still the same problem. In this point, I got worried the /system and /data partitions got locked
I re-started, went to stock Recovery, and wiped system and cache. Then, went to Fastboot a third time and tried again flashing VZW_XT907_4.4.2-KDA20.62-15.1_CFC_1FF_SVC.xml.zip. Guess what? Still the same problem
The phone turns on, but ALL apps keep crashing over and over. I can't even take an screenshot, as it immediately reboots.
Someone know what happened with it? And... how to fix this issue?
