How to troubleshoot logs of a bootloop failure

I've had my Note 4 for a while and after a few Lollipop update incidents I finally after a lot of hesitation decided to root my phone (with the TWRP bootloader) and disable the update notifier. Since then, I've always stuck to the latest stock version of KitKat 4.4.4.
Since I've rooted my phone, I made the following modifications that require root priviliges: I installed XPrivacy mod, YouTube AdAway mod, NoSafeVolumeWarning mod, PlayPermissionsExposed mod, and CrappaLinks mod for the Xposed framework. I also installed Titanium backup to freeze/uninstall the updater and AdAway. After XPosed was installed I had to change a line in /system/build.prop to 'ro.securestorage.support=false' to make 'S Health' work again. I did that with the 'FX' app.
That's it, I had made no more modifications and the phone seemed to work quite well for a month or so.
Two days ago I decided to try out Instagram, I've been quite wary with social apps but figured Instagram shouldn't hurt and everything was fine. Then I installed a bunch of dating apps, I started with Match.com and Tinder. Tinder didn't work because it required FB and Match didn't work because it refused to, probably because of denied permissions with XPrivacy so I gave up on them and uninstalled them.
But I also installed OkCupid and Motesplatsen and enjoyed playing around with these apps. They didn't seem to interfere with XPrivacy and worked rather fine. Motesplatsen was rather intense with sending me notifications of girls who watched my profile and sent me (rather strange) messages whereas OkCupid was rather calm.
Then something strange happened.
Yesterday I started noticing that the battery was draining considerably faster than normal during normal day. It was almost empty whereas it usually is half full after a full day, I also noticed that the phone was unusually warm. I forgot to put it on the charger and woke up today with a dead phone. I put it on charge and after about an hour the battery was full again.
When I tried to turn on the phone it was stuck on boot loop. I first tried disabling XPosed by "touch /data/data/de.robv.android.xposed.installer/conf/disabled" using the 'terminal' tool in the TWRP bootloader. It didn't help. I tried flushing the cache/dalvik cache but it didn't work either. Then I did a total factory reset, but that didn't work. I noticed that during boot, the phone froze so hard that it doesn't even respond to button pushes. I had to take out the battery to reboot (that's one reason why I never will buy S6).
So then I decided to flash the phone with stock KitKat once again using Odin and that finally restored the phone.
Now, here's one of my questions, how can things go so bad with a phone that not even a factory reset will fix it? We're talking stock firmware here, albeit it is rooted.
What boot logs could be worth looking into when such a thing occurs and what is the easiest way to extract them? The terminal tool in the bootloader seems promising, plus I saw a 'copy log to SD' option which I neglected this time.
I'm puzzled, does anyone know what happened? I made no root modifications in the process of installing these apps and they don't advertise themselves as needing root privileges. How can a seemingly inconspicuous app directly from Google play **** a phone up like that?

Issues After Root - Rotation and Encryption

Howdy,
I got a new Note 4 from Bell Mobility about a month ago...
I updated the software, rooted it and installed the Wanam modified Xposed framework.
I have lost the automatic rotation, except for the built in camera software. Nothing else will auto-rotate. Checked the gyroscope and checked a few 'leveler' applications - all tests pass. Oddly I noticed the camera software still auto-rotates, no idea why it is special.
I tried the Wanam Xposed module to 'Enable all rotation angles' it has made no difference. With screen rotation software, currently have "Rotation - Orientation Manager by Pranav Pandey" installed. Auto-Rotate On and Forced Auto-Rotate neither option will rotate the screen when I turn my phone. If I choose Forced Landscape, it will go into Landscape mode. The only way to return to Portrait though is to use one of the Force Portrait options though.
My other issue is with turning on Device Encryption... Using SuperSU Pro for su..
If I just go through the prompts without changing anything, it reboots but doesn't encrypt.
First I tried installing as a system app so I could use the Disable function in the Android Application Manager, as I did with my Note 2, SuperSU tells me "Not (currently) available in system-less root mode".
If I turn off "Enable Superuser" in SuperSU, encryption enables properly, but I am unable to turn the "Enable Superuser" again, it says it has to update, but the fails. Suggests a reboot and try again. Sadly, this did not help.
I had success with one of the exploit root methods, KingRoot. While this worked when my phone was encrypted, it wasn't stable and kept popping up stuff. I tried to replace it with SuperSU, there are a few guides written to do just that, but they all indicate that it is very hard to get rid of, regardless, none of the guides worked for me. I ended up resetting the phone and starting over...
I tried the CLI command to start the device encryption from a # prompt..
vdc cryptfs enablecrypto inplace password 1234567890abcdef
The phone rebooted a couple times, but took a very long time (hour plus) to come back to the Android Lock-Screen.. But still a non-encrypted device. If I intrupted the process because I thought it had crashed, it started up and immediately told me something when wrong with the encryption and I need to use Recovery to reset the device..
As for root methods, I was using the CF-Auto-Root at first, trying to look for solutions to both issues, I tried a few ways of getting SuperSU installed.. The last time I reset I tried the "SkipSoft Unified Android Toolkit" method. 'Grasping at straws' to get SuperSU installed into /system so can use the Applicaiton Manager to disable and enable it...
My mobile's specifics, if it matters..
Samsung Galaxy Note 4
Model number - SM-N910W8
Android Version 5.1.1
Baseband version - N910W8VLU1COK3
Build number - LMY47X.N910W8VLU1COK3
Currently have the Team Win Recovery Project v2.8.7.0 recovery software installed.
I am looking for suggestions for both issues, but really want to avoid resetting the phone if I can at all possible... Yes, I have Titanium Backup Pro installed, but have never actually gotten a restore to properly restore all my applications and data... I rely on it now just for the Uninstall and Freeze features.

For an update,
I also noticed that rotation works on the Lock Screen and in the camera applicaiton.
If I rotate my screen on the Lock Screen, the red handset picture and camera icons rotate.
If I rotate in the camera application, nothing changes position, but all the icons rotate as well.
I'm still completely stuck though, open to suggestions...

For rotation, it is likely caused because you removed the com.thingy.facebook system app. I tried removing it because I thought is was bloatware but read somewhere that messing around with it cause the auto rotate and pedometer to fail. I fixed it by reflashing the rom without data wipe then never removed it again. Page Manager is safe to remove though.

Thank you,
I had it frozen for a while, completely uninstalled it, trying to see if lack of space was why I couldnt' get SuperSu to become a System App..
I will try to put the facebook app back to see if that helps. Hoping I don't need to do a ROM reset, but if that is what it takes.

I tried installing FaceBook from the PlayStore, no change.. So I uninstalled it again.
Took a backup in Titanium Backup and in TWRP.
From the stock image, I extracted system.img.ext4 and used SkipSoft's application to make just this file Odin flashable..
Flashed it.. When I got back to Android, my phone hadn't reset (what I was going for ), rotation is working, SuperSU still giving root access
I went back into Titanium Backup, the freshly installed apps were listed on top, because there was no backup of them.
Froze each, one at a time and checked the rotation after each.. Froze all the apps with no backups, and rotation stayed working, which I thought was odd for what fixed it.
So.. The Facebook applications are all frozen, as they were before I erased them the first time, and rotation still works. Hurray..
Now for the device encryption, I will keep messing with it.. Trying FlashFire to mount System as RW and to write the newest version of SuperSU, hopefully it will install to System this time.
Thank you again.

This is amazing, can you please post the odin flashable file? I am having this exact problem right now because I removed it in TB. Is it just the facebook file that are flashed? Thanks so much in advance, you're saving my life here

Help! I killed the second screen!

I removed some stock apps using adb, and something broke my second screen. Everything seemed benign, but I jacked up something. Now my phone keeps displaying "Unfortunately, second screen has stopped." Thanks!

Do you have a Nandroid of your install or backups of any of your apps through TiBackup?

Non rooted with no backup
No.

What model do you have?
Just use one of the unbricking methods here on xda to reflash stock rom and you should be fine. Use LG UP to flash the latest kdz.

In had this happen many times tweaking things through adb. Never did figure out what I did to disable the screen. I found a simple factory reset fixed it. Assuming your are not rooted and just forced an uninstall of apps via Adb.

I had this happen (on VS995 i.e. Verizon non-rooted on Oreo) after I used adb to uninstall the 3 weather packages (com.lge.sizechangable.weather, platform & theme.optimus) since I don't use the weather widget. Reinstalling from the original apk files fixed the problem; they were listed as Weather, Weather Service (this one fixed it) and Weather Theme. So my guess is one of the packages you uninstalled. I tried disabling them first but couldn't, thus the uninstall. Couldn't reinstall through adb but just running the apk install once I found where they were hiding in the file system fixed me up. Argh!

System lags and crashes, makes impossible the use

Hi. I have a Xiaomi MiA1, Lineage 16.0 (I try to update it two or three times per week). It is rooted. I use openGapps.
I have a problem since yesterday: suddenly, my phone got a lot of lag that makes impossible the use. KLWP got closed (it stopped being the default background), Nova Launcher was lagging and restarting several times. Openning any app was impossible, including the settings and system, it freezes and closes, returning to the launcher home screen... I tried to stop, clean data and delete klwp, nova, but i got the same result. The minutes passed and it got worse. Finally, the phone freezed, the clock wasn't working, so the only solution was doing a manual soft reset.
So, yesterday I did a dirty flash, because I didn't have a recent backup. I used SDMaid database feature in the morning so I tought maybe it was bad executed and was the origin of the issue. I tried to rescue some information (to backup some app data) with oandbackups. I cleaned caché and did a Factory reset. It seem to work. and do a clean installation. at first, it seem like it worked. I installed the apps I had by my Google account, and went to sleep. Today, it was ready, I turned it off and charged it, and in the morning: again the crash. So I did a clean installation. Again, it seemed to work. It installed all my apps and... crash again. I fear it could be some launcher issue? any prob with lineage? Any app? How can I know whats happening?
Sorry for my bad english. Any help would be apreciated.

Keeping in mind the kind of apps you mentioned, I'd go with an app+data backup of those apps you installed and uninstall them completely, check if problem is still there.
I suspect you're facing a compatibility or configuration issue, since both apps are related to home screen.
If problem is solved, first read if those apps are actually compatible with ROM and OS version, then you could try to install just one app, without data, and check if things go well (give it a day), same with the rest until you can confirm OS is working well with apps just installed, no changes made in them yet... In other words, were trying to confirm that problem comes from apps and/or their configurations, so you could somehow report those issues to apps developers. You can use Catalog or other apps to record System logs until app crashes.
On the other hand, if problem is still there, even before you started to reinstall apps, then Dirty flashing isn't a good choice in that case, since it preserves System configurations, no mention your device is rooted, were user changes are present... you are opened to different problems, worse if you use an old Magisk version, or installed modules there, or apps that force your OS to do things it doesn't do in it's original state.
So, as you were so dare to go with a dirty flash, you could better go with a clean flash instead.
Erase any system lock protection (fingerprint, pattern, etc), do a ROM Backup from TWRP, flash latest firmware and make a clean install of the latest version of the ROM of your choice, keeping in mind their own flashing procedure.

As with above reply, if a completely clean install doesnt work, consider going back to a previous lineage release. If it still doesnt work, consider a full EDL stock rom reflash using MiFlash -- then flash your custom rom.

I made a clean flash in the morning, with the same results, so there's when I thought it could be an app the main problem. It worked with Nova a few hours.
I just followed your instructions, I installed the last firmware (the jan one) and the last rom of lineage. I didn't installed the apps in my google backup so I can install them and check how is the behaviour. I will install CatLog so I can check the logs too! I really hope installing the firmware was enough. Thank you very much!

I was planning to reflash the custom ROM but I couln't find the latest one that's compatible with MiFlash. I really hope the clean install is enought... thank you

I was planning to reflash the custom ROM but I couln't find the latest one that's compatible with MiFlash. I really hope the clean install is enought... thank you[/QUOTE]What our partner said was flashing stock (original) ROM.
In any case, if you went with a clean flash, try to leave your system free of user installed apps for a few and check how it goes.

Youtube not loading - possibly uninstalled required app to operate

Hello
(device Samsung Galaxy Tab A 10.1 2016)
Today i have downloaded Titanium Backup Pro and wanted to freeze knox to get rid of the annoying security notification. I had freeze some associated apps which contained "knox" in the name but did not help.
After then i uninstalled a few apps even system apps which i was sure i dont need (there was not many i have uninstalled, really i was sure i can without problem. one of them was youtube). after filtering out frozen apps i noticed that there is also system webview frozen and smart things which i am sure i did not freeze. i believe that titanium backup was bugged. I tried to defrost but it kept remaining frozen. so unfreeze does not work
I dont know if this caused issues with youtube vanced but before i could watch youtube vanced but now it was loading forever right after opening.
I decided to perform factory reset but not through system settings but booting into twrp recovery and ticking dalvik, data, cache and internal storage. After factory reset i realized that the previously uninstalled (debloated) apps through titanium backup arent restored back. I have read on the forum that by performing factory reset the uninstaled aps should be back. but they are not. why? even installing through adb back it gives "package installed" in the adb terminal but the app is nowhere.
And after clean reset and installing youtube from google play it keeps loading. I see only the bottom menu (Home, exlore, subscriptions,library), at upper part search bar and i can enter settings but the screen is white and is circling/loading forever.
I am afraid that i had accidentally uninstalled some important app through the bugged titanium backup and after factory reset i did not get it back so i cannot browse youtube and even youtube vanced (any of them)
What do they have in common?
(i have tried to reinstall back google packages all at once through newest adb and fastboot toolkit, it gave message "package installed to user 0" but nothing seems to happen on my tablet)
Please recommend me some solutions to solve my issue.
Thank you
