Infinite boot / slow boot - LG V10 Q&A, Help & Troubleshooting

The phone is rooted and has a few Xposed modules installed; stock ROM.
I shut the phone down every night. When I wake up and turn it on, every now and again it gets into an infinite boot - not a bootloop (at least not in my understanding). It either stays on the LG logo or the Tmobile logo. Sometimes it boots just fine and quick, sometimes takes a minute longer. Other times I have to hold the Power + Volume Down for a few seconds to reboot it, and it boots fine after that. Yet other times, I have to get into the Factory Reset mode and rebuild the Dalvik cache form within TWRP, after which it boots fine.
The weird thing is that when nothing is changed from the moment it loops to the moment it boots fine; it may only be a reboot away. Granted, I do have (quite) a few things frozen and/or removed in Titanium Backup, but should it affect the boot?
Has anyone experienced anything like that?

Attached are the warnings and errors captured while LiveBoot was running. The lines go really fast, and Nexus 5 shutter isn't capable of going that quick (that's why you can see double lines in certain places). The phone booted after I switched to my swap battery.

Just an update, I restored the earliest Nandroid backup and instead of uninstalling these apps, I froze them in TB. No boot issues so far.

Another update. This morning the problem seems to be back, it was stuck on the T-Mobile logo. Although I can rebuild the cache, it's worse now, because I haven't disabled any LG or system apps since the last restore.
Update to this update: after the T-Mobile logo reboot, it now stuck again on the LG logo and took two 5-minute waits before reboots; it booted fine on the third (essentially, the fourth) reboot upon swapping the battery.
Does anyone else experience this?

[Q] gt-i9100g freezing during boot or a few seconds later

About 3-4 months ago I flashed stock ICS into my Galaxy S2 (I did not wipe the cache, which I discover today was a mistake). I noticed a few weeks later that it was a bit unstable, crashing, restarting, etc. I did not care much and just kept using it.
Today it just would not boot, so after 1 hour trying, I managed to keep it alive (using safe mode) long enough to go to setting and have a factory reset.
Then it would not boot again.
From there, I tried several times the factory reset and wipe cache (using volume up + home + power menu). It would sometimes hang on the "installing applications" until several restarts it would eventually go. Then it would hang randomly on startup "s" video, until I managed to get to the welcome screen - which freezes pretty much on the first or second screen (choosing language and date/time).
I flashed I9100GXXLPY_I9100GDBTLP3_DBT and got the same result.
The phone is not rooted, there is no clockwork and I can't even access the phone to put it into debug mode.
Anyone has any more idea of what can be done besides throwing it on the trash? :/

[Q] Boot loops, CWM crashing. Stuck

First of all, I have the straight talk version of this phone. Second, here is everything I can do and what the phone does:
What I CAN do:
Enter CWM recovery (Though, sometimes it will crash instantly, the Power button will not work)
Enter download mode (Thanks to USB jig)
Use the phone (Max of 5 mins before the phone crashes.)
Fun information about the phone:
The Power button is a gamble. Sometimes it will work, sometimes it wont.
If I turn the phone on (Have to take battery out then put back in), and let it go to sleep. 9 times out of 10 the phone will crash.
CWM crashes...very often. Very often in this case can be defined as 'always'.
Here is what I HAVE done:
Attempted to flash the stock ROM
Factory reset
Wipe data and cache (Though, CWM crashed both times on these, don't know if it fully cleared them)
Here is what I attempted to do:
Perform a ROM wipe using a script from here: http://forum.xda-developers.com/showthread.php?p=38199542 (This was unsuccessful because everytime I try and do this, CWM crashes before I can start the process)
That ends that. I just want this boot loop to end...and restore functionality back to the power button (I'm thinking flashing back to the stock ROM will solve this). I have done nothing to cause this. The only thing that happened before the boot loop is the battery was low and when I turned the phone on (it was in sleep mode), I accidentally pressed the power button twice, which first froze the phone. Then, crashed the phone. Ever since then it was in a boot loop.

LG Volt Unresponsive Presses? Factory Reset Results In Talkback Screen & Long Reboots

LG Volt Unresponsive Presses? Factory Reset Results In Talkback Screen & Long Reboots
I'm not even sure how to title this thread. It all got nasty.
The most I've done so far is root my LG Volt.
I was just recently pursuing building an AOSP ROM and even used "dd" to back up EVERY partition to my computer.
Then, I also had wiped the laf partition to get to fastboot rather than "recovery" (download mode (volume-up&power)). THEN, I fastboot restored the backed up laf partition.
This was all probably 2-3 weeks ago.
Now last night, my phone became more and more unresponsive, to where I just had to reboot and the unresponsiveness didn't get better AND the script used for mounts to my sdcard didn't work and when I even tried to "su" while in adb, I never was able to get root for some reason (which likely explains the permitted root apps to fail to run).
And it only gets worse. One of the times I rebooted, the keypad didn't come up to decrypt the drive. Eventually I gave it time and it came up. But even BEFORE decrypting, I'd get notices of apps failing like Settings (and I hadn't even booted yet).
At this point, I didn't have many (any?) options left. I can't adb/fastboot with Volume-Up/Down & Power (lg nerfed it?)
I mean, I can boot to those (screens?), but can't use the programs on my computer (no device is found in those modes, unlike when I could adb while fully into android).
So, I have been able to get to the fastboot screen and wipe cache and also factory reset (wipe data).
When I reboot from fastboot, boot takes about 6-7 minutes and android starts with the Talkback screen.
But again, the screen presses are nearly unresponsive. When pressing "Next" finally registers, my phone ends up rebooting and NEVER boots up.
It starts with the LG boot logo and the smooth "glimmer" animation. After maybe 15 minutes, it seems like it reboots again (or maybe a 2nd stage of boot or something?) and that "smooth" animation now becomes "jittery", like the cpu is really being taxed.
Again, I hadn't flashed any ROMs with this phone yet, so surely the factory reset would've brought it all back to a clean state.
Also, I DID remove my old swollen battery (gassed-up for maybe 2 years now (yes, I know I'm practically playing with fire)) too, and put it back in.
I would always have my phone plugged into my computer so it would always be charged.
What are my options at this point for my 3+ year old phone? Is there a way to get to adb/fastboot so I can restore what I backed up before? Can I sideload a ROM from my sdcard? ...?
What I'd like to do is fsck the data partition and maybe even run badblocks on it.
While typing all this out and reviewing it, that part of the boot with the jittery logo disappeared, so it may now be onto the stage of getting back into the main android start screen. Ouch, that boot audio really struggled, again like the cpu is really being hammered.
Nope, the logo is coming back up again and really struggling to even display the logo. The G and "Life's Good" is still fading in VERY slowly.
Well, luckily I was still able to use the old flash method https://androidforums.com/threads/guide-brick-recovery.893332/
Now I look to restore the partitions I had previously backed up with dd.
The problem is, I never backed up the decrypted dm-0, but rather the encrypted userdata mmcblk partition.
Does twrp or something have the ability to restore the encrypted mmcblk partition and what I guess is the small "encrypt" partition that I assume contains the encryption key?

Honor 8 stuck on boot (no fastboot, no recovery, stock rom)

Hi guys,
first of all thank you for taking your time and reading through this. I'm not completely new to android, nor using fastboot and recovery. I flashed a few phones over the past years I even resurrected bricked ones. However I have no idea what is happening to my Honor 8. One thing to mention, it's the latest Nougat update, and a STOCK ROM.
It all started this afternoon. The phone suddenly reboot while using it. After that, the android screen came on, then Honor animation and.. freeze. Completely. I had to reboot using the long press method since it was stuck between the bootloader and the rom itself. It started up ok after that.
An hour passed, and while I was typing a message, it froze again. I could go back to home but the phone was really slow. After opening up Messenger again, it froze completely. Had to restart again with the long-press reboot method. It started up ok, entered the sim pin and upon entering the screenlock code it froze again, completely. Long-press reboot, again.
Since then, the phone won't boot. It gets stuck every time on "Honor powered by Android" for about a minute, then it reboots itself. I even got some weird green screen with a blue and a red rectangle, but that just stopped after a few reboots.
I mentioned that I know how to recover and fix stuff when something acts weirdly, but that's not the case, I can't do ANYTHING. No fastboot, no recovery, no button combinations, I can't even turn off the phone. It just keeps rebooting on and on, and yes, the battery will eventually die, but I have no access to any recovery options. I even tried dload but no luck.
It's still under warranty so I can send it back but I just rather fix it at home (without taking it apart), because I don't want to wait 3 weeks to get fixed. But it seems like that is the only option right now, I have never ever seen anything like this happen.
Any help or comment is appreciated. Even if it's not possible to do it at home (hardware issues?), I am really curious what can be the cause of this issue (damaged rom, filesystem permission issues?).
Thanks.

sm-t820 freezes after boot.

Hello,
maybe someone has suggestions on what to look next or how to determine where the problem actually is.
My Galaxy S3 Tab 10 has suddenly started to freeze after boot + ~1-2min. Even if I wipe everything it freezes even during the initial setup. It is possible to complete the initial setup in minute increments.
When it freezes there is nothing I can do, only Power+vol down for reset. Even to power off I need to press Pwer+vol- then boot it in recovery and then choose power off.
But if it's booted in recovery it can be on for a while and nothing bad happens. That let me think it is more software than a hardware issue.
Have tried to reinstall stock ROM, a few custom ROMs, all the same.
It has not been dropped or "watered" or some other abuse.
Any help?
Thanks!
