S6 Edge boot loop/now logo showing before shutting back off. - Android Q&A, Help & Troubleshooting

I rooted my S6 Edge a couple of days ago with no problems. I later added xposed and a couple of modules, no problem (apart from swipeback needing removed after it disabled my camera/gallery). Last night I shut my phone down and put it on the charge for the night. Today after turning it on it was stuck in a boot loop. I have been searching for fixes but there seem to be many different scenarios. I have tried to boot to recovery multiple times to do a wipe partition cache as that seems to the general fix. Problem is I am only able to get into TWRP. So I tried to do a default wipe with TWRP (Says wipes Data, Cache, and Delvik (not including internal storage) ). My phone now only boots to logo before shutting back off. I assume anyway because it isn't boot looping anymore and holding the power button gets the same result, logo then black screen again.
I am able to get into TWRP menu though I should add just about any option I choose, after it executes/completes the phone freezes and needs to be forced off/restarted. It has done this since TWRP was installed.
I am also able to get to ODIN mode.
If I remember correctly it is the G925F Global model. Running 6.0.1 stock, rooted using SpaceX kernal.
This is the process I used to root: edit: Seems I cannot link until I have at least 10 posts. How to Root Galaxy S6/S6 Edge on Android 6.0.1 Marshmallow!
BY MAX LEE google that and top result should be the site I used.
Any help would be greatly appreciated. If you would need anymore info I will gladly do my best to give it. I would like to fix this without losing all my data, apps pics music etc. But if all else fails I am prepared for that.

[Q] Random reboot then data wipe

Hi there,
So I was on Skype to my friend on my i9300, running stock 4.3, rooted, with yank555 kernel and with PhilZ 5 recovery. All these modifications were done about four weeks ago and the phone has served me perfectly well until today.
The flashing Samsung logo that comes up just before the phone boots appeared and the keys stayed lit, when nothing happened for a minute, I held the power button until it reset. Next, the phone took a good two or three minutes to boot and seemed to have forgotten all the information I inputted into it. I still had most of my apps but all the sign in information was gone and all the Google Apps had to reinstall themselves.
There seems to be no cause for the break down, and I don't have a recent backup as I haven't planned to flash anything until 4.4 is officially released. Does anybody know what could have caused this or if there is a way to recover my data?
Cheers.
Unplanned system shut down can partition corruption, reasons for it can be various -battery voltage suddenly dipped, kernel panic etc.
Data on your internal sd should still be there, as on the external sd. Anything else will be gone as it sounds like your data got wiped.

Automatic soft (re)boot issue

My i9300 seems to have lost control on (soft?) boot:
- I flashed a 5.1 omni ROM that made me very happy because really stable enough for me to use multiple apps at same time.
- One week after, I started getting unwanted soft reboots (skips Samsung boot screen), leaving me approx 40s of system use before 5s freeze followed by reboot.
- These soft reboots are weird: if I force shutdown (power menu OR removing battery), the phone boots anyway, by itself!! And I think this is still soft boot because it still skips Samsung boot screen.
Additional info:
- I wondered if my power button was messed up but I don't think so: I would not have this freeze before reboot, plus I have no reboot while in recovery.
- I saw some SMS problems: received one from my provider, and I kept receiving it again at each reboot (same one 50+ times). Any link possible?
What I tried without success:
- Remove SIM and SD card
- Remove battery for a day
- Change battery
- Re-flash recovery
- Wipe System + Data + Dalvik/Cache then install paranoid android (now I can't even boot in anything else than recovery btw)
I'm lacking android system knowledge but it looks like there is a location in "soft reboot zone" that is locked, and the phone keeps reading it and rebooting infinitely. Is there a way to clean this? To forbid soft reboot maybe? Note that I've been flashing various roms for 3 years on this phone and I never saw anything alike.
Any advice is welcome, thank you for caring !

That SMS thing is strange
Have you tried another recovery version? Or perhaps changing recovery? This isn't a normal issue, since you already tried installing another ROM.... You can try another Kernel either
If none of this works, consider flashing the original Samsung's ROM or some samsung-based ROM (they usually do a nice clean-up, at least for me these ROMs fixes the majority of my problems)
@blint6:
1. Maybe the hardware though. This you can test by flashing actual firmware and running it under normal conditions for 1d.
2. Reboot is a known reaction to RAM-lack on LP, too. Flash Omni cleanly and run it for 1d without GApps and bigger apps.

Android heavy lagging/freezing/desktopscreen moving left<->right [HELP]

Hello guys,
So, i have rooted my Device (BQ M5) 1 Month ago and installed Xposed on it. Everything was fine until yesterday, where i was underway and streaming via Chrome a video. I didn't close Chrome and simply locked my phone. Several minutes later, when I tried to unlock my phone, i directly noticed heavy lag (response 2seconds - 2min - locks device). I thought a reboot might solve this issue, but i was wrong. I started to uninstall several previously installed apps and tweaks (where the newest App/Tweak was 8 days "young".
After a reboot, still heavy lagging. I opened TWRP and Cleared Dalvik and Cache, did a reboot in System, Recovery and Bootloader. I even flashed the device with a complete fresh OS. The problem still remains. After several re-flashings, some cache clear, factory resets and SuperSu unrootement i somehow managed to get it to work again. So I started from 0 again, and installed all previous apps, and root apps. Everything was fine for several hours (connected to Wi-Fi), so i was installing Xposed again, with 2 apps/tweaks: Flat Style bar, youtube adaway. Everything was still allright untill i left the house. I unlocked my device 50min later (for the first time when i left my house) and boom, the lagging was back. (Don't have internet outside my house).
As soon as i came back, i retried everything to remove the lag, however I did now several things in addition for over 3h and the lagging sill remains. I down and upgraded the OS, formatted the data, did every clear in TWRP and Bootloaded that i could find. I reset it via Settings and flashing. I installed SuperSu and de-installed it.
I don't know what else i could do, to solve this issue. The lag remains when using TWRP, Bootloader, using the Device, or when the Booting animation of android appears (slow animation or with a "fps of 0,05").
Please help me!
Device: BQ M5
Had Android 5.1.1. on it and Installed xposed sdk22 arm, and installed SuperSu via TWRP.
All files were downloaded from official posts here on xda, or from the brands website.
p.s. Even the littlest information which could help, please share!
p.p.s Here's a video that shows whats going wrong. After the reboot the booting animation continues like this around 1-3min. and then at the unlock screen, the "lag" still remains. What i noticed too, is that the charging animation in the top right is running flawlessly, however opening apps and all the rest is really slow!

[Q] Encryption unsuccessful on LG G3 D855 Stock Android 6 Marshmallow

Hi!
I got some major problems with my G3. I was on stock Android 6 (rooted). Worked fine for some months. Then I decided to encrypt the phone and activated this option in the normal android settings. After some time the phone restarted and I got the "Encryption unsucccessful" page and cannot do anything anymore.
After reading through the help forums I tried the following steps to solve it:
- factory reset
- wipe eveything in twrp and flashed system, boot, modem manually to Android 6 again
- repaired all filesystem partitions in twrp
- many many more factory resets
All didn't help. The only thing that changed is that when coming to the "Encryption unsucccessful" page now the phone hangs up after the next option I choose (shut down or restart or factory reset) so I have to take out the battery to restart or shut down.
Any suggestions how to solve it and maybe also any suggestions what might have gone wrong? Don't want to kill the next phone the same way by just enabling encryption!?

Phone soft bricked, factory reset / loading new ROM doesn't help

My phone (Nexus 4) appears to be soft-bricked, and will not boot up. When I turn on the device, it appears to get part way through the boot process but it never completes, and the bootsplash just keeps spinning forever. The top of the phone where the radios/gps/etc are gets very hot during this time.
I've tried: clearing caches within TWRP, factory reset, loading a couple new ROMs, wiping all partitions and reformatting, updating TWRP. Nothing seems to help.
I'm starting to think it's a hardware problem, but I'm hoping that someone might be able to give me some ideas that I haven't tried yet. I can get into TWRP and can load ROMs.
Some background: My phone is a Nexus 4 (mako) and had Cyanogenmod 13.1 prior to the issues, which has been running fine since last year. Recently my phone was acting glitchy/slow, so I decided to clear the cache and dalvik cache a couple weeks ago. This worked great and got things working well again. When I set things up again I also decided to start using DroidWall, which was the only app on my phone using root. About a week ago I also replaced the battery inside the phone since my old battery was shot and could barely keep a charge. The new battery has been working well, and does not appear to be the part of the phone heating up when the phone is stuck booting.
An update. I found that with the Slim ROM loaded, I can run `adb logcat` while the phone is booting to see what's happening. Lineage OS does not seem to ever get far enough to be seen by adb.
When viewing the Slim logcat, there are a lot of logs generated. Within, there are some DEBUG and backtraces displayed. And, I think the phone may be stuck trying the same thing over and over again as I've seen a section appear about the camera several times.
Earlier today I opened up my phone again, and noticed some pressure contacts on the back cover of the case. I cleaned them all to make sure they were making good contact, but it hasn't helped.
