Weird problem which fixed itself (halt during boot)

Hi All!
I have P8 Lite running B564 EMUI 4.0 (no root, no TWRP, no other mods)
Over the weekend I had the problem like below:
1. Device rebooted itself
2. Device started to boot but hanged during boot (animation stopped at one of the frames)
3. I've manually forced reboot
4. Device started and yet again hanged during boot (same step).
5. I've left it for 30 minutes but nothing changed so I've manually rebooted it.
6. The same... again... again again...
7. After 1 hour or so the device suddenly booted up properly.
Later on that day I had some problems and it forced me to wipe the device clean... (I was unable to get logcat before the wipe so don't have any logs)
Once I set up everything - it is working so far but...
Question is....
Did anyone have the same (or similar) problem?
If yes - please share some info as I would like to do some troubleshooting.

A5 (2016) Stuck on Boot-screen (Samsung Logo) after Software Upgrade

Hi guys I kindly require your assistance concerning my Samsung A5 2016 A510F, device was running android 5.1.1 before I updated to android 7.0. Here's the reason why I updated, device was acting shaggy it would suddenly close apps during operation. for an example with error "messaging has stopped working" would close most of the apps with the same error or suddenly restarts itself especially when the battery is less than 50%.
So I then attempted to do OTA update but failed to install "error, invalid file" so I went the Odin way, Downloaded stock firmware and flashed via Odin, everything went smooth until reached the "apps optimization 40 of 40" stacked there for about 30 minutes until i decided to restart the device, upon restart the device no longer went pass the Samsung logo stacked there.
Here's what I tried to resolve the issue:
- Cleared cache
- Factory reset
On recovery screen i noticed an error about "e: failed to mount partition" I tried almost every solution I came across to on Google with no luck. I then tried flashing to this custom rom https://forum.xda-developers.com/samsung-a-series/development/rom-resurrection-remix-rr-v6-unofficial-t3765542
Installed successfully but gets stuck on "checking for software update" I reinstalled the custom ROM again but this time without the GAPPS device booted successfully to home screen, went back to TRWP this time installed the GAPPS rebooted, it went successful, however device is unusable it keeps popping error "google play services closed" every 2 seconds.
Please help, is my phone officially dead I need clarity. Your assistance will be highly appreciated thanks in advance

'System UI isn't responding' and 'Process system isn't responding' w/ restarts

(Moved from general discussion)
Hey all,
I've run into a bit of a pickle..
I replaced the screen on my S8 (SM-G950U) and after booting, it immediately gives 'System UI isn't responding' and/or 'Process system isn't responding'.
Shortly after (1-3 minutes) the phone will reboot. The errors may appear 1-2 more times before rebooting.
A bit of info:
Model: SM-G950U
OS: G950USQU4CRE9
Steps taken:
Clearing cache does nothing.
Factory reset via recovery mode has no change.
Flashing stock ROM (same version) with ODIN does nothing either.
Before restoring I was able to go in and see the RAM was reporting what I assume is normal (~30% usage)
Also the front camera was no longer working, but I've replaced that as well and haven't had the phone on for long enough to get through the initial setup to test.
Anyone have a potential solution / suggestion? Any and all help is appreciated. Thanks!
Edit:
It might also be worth noting that the shutdowns only happen after booting. There's no issue when entering recovery / download mode.

Havr you tried safe mode?

I know this is an old thread but hoping to get some guidance. I am facing the exact same issue on my at&t s8+ snapdragon as mentioned above. The device is unrooted and was with stock oreo rom. suddenly started showing either "system iu isn't responding" or "process system isn't responding". Later the device started hanging and kept restarting. It restarts from samsung logo instead of the device model name unless force restarted. This cycle keeps happening. I am able to access download mode and recovery without any problem. recovery initially shows "installing update" followed by "no command" but then works normally. The device doesn't power off even from recovery, it keeps rebooting. I have tried (1) cache wipe (2) factory reset from recovery (3) safe mode (4) installed stock rom without problem (5) installed latest stock s8+ unlocked xas pie rom without problem (6) installed latest stock s8+ sprint version pie rom without problem but i am unable to even end the initial device setup as the device keeps hanging with these errors and restarts. Any ideas would be appreciated.

G950F (Austria) - not able to boot up: 'Installing system update' leads to error

Hi all, maybe there is someone active here who can help me bringing my SM-G950F back to life without losing my app / user data.
Last thing I did was installing an App called 'Airwatch Intelligent Hub' in the Google Play Store. This for some reason caused a reboot and this is where trouble started.
Here's what happens:
My phone is shut down - I'm turning it on.
'Installing system update' message shows up
'No command' error message shows up
After some time, an additional error message in the stock recovery shows up -
I am selecting 'Reboot System now' - I have Secure boot enabled, entering PIN
Loading animation shows up
The phone reboots during loading animation
I have to enter the PIN for secure boot the 2nd time
Loading animation shows up
Phone seems to start - 'optimizing app m of n'
Loading animation shows up for some time
Back to the 'installing system update' screen
Error message in Android recovery
After shutting down the phone, I am able to repeat the whole process
Photo story of the boot process:
Here's what I have tried:
Cleared cache out of the recovery
Did a full power circle
Tried safe boot, but without any success
...
Downloaded the stock ROM (Andriod 9) for Austria (A1)
Flashed the stock ROM via Odin 3, but with the CSC_home to avoid a loss of user data
The process finishes successfully, but after starting the phone, the process described above starts...

Hey. First of all they app you tried is the reason of this (maybe) so you need to wipe it . Don't worry it be fine but you have to loose your data in order to use it . Open recovery somehow and then wipe data then try restart may it work if not then flash stock rom its not compulsory to flash Austria ROM i mean you can flash other versions just the file should be for sm g950f. I hope may it helps you just give it a try. Data is not going to be usable unless your phone is.
StayBlessed.?

Pixel 4 stuck in bootloop after last automatic attempt to update | Updating manually through ADB does not work

Hello,
Looked into the boot loop issue quite heavily over last couple of days after facing it myself and it seems for majority manually pushing the update via ADB would solve it, but not in my case unfortunately.
As mentioned in the title, boot loop began after I rebooted the phone and it had a pending update to 12.1.0 (SQ3A.220605.009.A1, Jun 2022), however it did not complete. It displays Google upon start, shows the animation, then onto G logo, progress bar comes up below it and freezes in couple of seconds. Then it restarts and does this all over again. Left it charging and in this loop overnight, for at least 12h, but there was no change.
Details:
It's a stock build, bootloader is locked
Bootloader version: c2f2-0.4-8048765
Current version: 12/SP2A.220505.002/8353555
What I tried so far:
Various reboot attempts in different intervals e.g. manual reboots while holding power button ; Manual reboots through recovery mode (some have reported positive outcomes when doing it this way couple of times in a row)
Applied updates from ADB:
12.1.0 (SP2A.220505.002, May 2022)
12.1.0 (SQ3A.220605.009.A1, Jun 2022)
flame-ota-tpb3.220513.017.b1-853b2f95.zip (The Android 13 beta, tried it as a last resort)
All updates are verified and get installed successfully according to output on the phone and ADB (complete with status 0), however version displayed in recovery mode never changes, it always remains as 12/SP2A.220505.002/8353555, hence I am assuming, that update gets stuck/corrupted
Tried flash.android[.]com - would not work as device bootloader is locked, but as per above, pushed update manually from ADB with little luck
Tried pixelrepair.withgoogle[.]com, but it throws an error, that device version is newer than that of the tool
As bootloader is locked, don't have the option to try some custom recovery tools out there, e.g. TWRP
Has anyone come across with such or similar issue in the past, where update cannot be pushed manually from ADB, accompanied with a boot loop? Any thoughts on how to resolve this? Would it be possible to at least clone the device into emulator and accessing it that way to get to non-backed up pieces of data I need?
I have not tried factory reset, as I am trying to avoid it and have it as a last resort, since while majority of data is backed up, there are some critical items and apps which are not, such as Google Authenticator, which would get me into a tricky situation with some of the 2FA services, so I am trying to resolve this without factory reset for now.
Thanks!
