Boot loop - Samsung C9 Pro Questions & Answers

I tried to root my phone.. without installing any custom recovery i just installed magisk manager then the zip file and started recovery booting (by pressing home+power+vol up). First it showed installing system updates then its displayed that failed to open recovery cause no such file. Now i cant reboot my device. There is a boot loop. I have tried wiping cache partition, data factory reset but still it dosn't opens. its stuck in samsanug logo page and keeps on booting again and again.

[Solved] System cannot boot, stuck in recovery mode.

So I had a problem where TWRP counldn't mount system so I tried to format within twrp then I formatted in fastboot. TWRP can now mount it and write to it but when I try to boot to it, it won't load anything but the logo shows (not bootanimation) and shuts down. Then it reboots into recovery.
Edit: Fixed the problem, flashed another rom zip

Failed to mount any partition / Kernel Panic / boot loop / Galaxy S5 klte

Phone was running stock os. I rebooted my phone and it's now stuck in a boot loop. I tried to reinstall it through Smart Switch and it's still stuck in a boot loop.
After the reinstall it goes to "Installing system updates" and almost right after it stops and shows "Erasing" for a second. It then reboots a few times and it usually goes to the Kernel Panic error but it has also gone to Manual Mode once to try and install the updates but then it fails to mount any partition.
I've tried installing Lineage OS (I used it before I went back to stock os) through TWRP and I also got the same errors. I was unable to mount any partitions and left the phone without a battery for a few a day.
When I tried again just now I was able to mount the partitions but installing Lineage OS or stock OS was still not possible and it gave me the same errors again.
Is there anything I can do to fix this?

Another error: imgur.com/a/xPHdm
EDIT: After trying for three days, it suddenly booted. I can boot to the OS but the phone still crashes and boot loops every time. If I go to recovery and wipe cache it will boot again. What can I do to stop it from crashing and going back to boot loops?

[SOLVED] Unable to enter TWRP/Stock recovery and can't boot into system

Hi,
I have been using my P Smart (FIG-LX1) for a while with LineageOS 16 and decided to move on to Android 10. Installed LineageOS 17.1 (found it on this forum) and pph-Magisk 20.3 for root - it did work, but the system was unstable so i decided to try AOSP 10.0 instead. I entered TWRP, wiped cache,dalvik,system and data, flashed the ROM, gapps etc. It was advised to now flash stock recovery and use it to do a factory reset - and now i'm stuck here.
After flashing the recovery_ramdisk img the phone stopped being able to enter any recovery at all. The system itself does not boot (stuck on the "Your device has been unlocked (...) Your device is booting now..." screen forever), the recovery never appears (previously in the start screen with 'unlocked device' warning it used to suggest pressing volume UP to enter recovery, now it only shows "Your device is booting now"). As i can still access fastboot, I tried flashing TWRP again - the TWRP splash screen does appear, but the phone gets stuck on it. Also tried flashing another system's img - nothing changed.
Is there anything I can do or did i just brick it completely?
Thanks for help!
SOLVED:
Apparently running fastboot erase on system and userdata partitions made me able to boot into recovery/erecovery again. I do have another problem now, but it's not connected with this one so I will create another thread for that.
Could you try help me? I can't even get ADB to work anymore

[solved] stuck on bootloop after flashing los 17

steps i did:
installed twrp twrp-3.4.0-1-markw
flashed lineage-17.1-20200920-UNOFFICIAL-markw by shiabzzz
wiped data and cache, excluding internal storage
tried to flash gaps but failed due to error 20
flashed magisk
reboot.
now im stuck on bootloop. i know i should have deleted data before flashing the rom, not afterwards. when i press power+up it's not going to recovery.
how can i fix it?
are gaps mandatory for it to boot?
will my phone turn off when it runs out of battery, will i be able to go to recovery then?
update: i can access fastboot mode, but when connecting to pc and trying to boot to recovery it says "waiting for device".

Phone stuck in bootloop. Recovery says directories not found.

I performed a factory reset from within the OS and when it restarted it was stuck on the Samsung splash page. After this I performed a reset from the recovery menu. Now the phone was stuck in a boot loop. At this point I re-flashed the factory ROM from ODIN and it is again in a boot loop. Sometimes it makes it to setting up the apps but just resets again.
For some reason the phone attempts to install an update whenever I enter the recovery and once there it states that it cannot locate files. The location of these files is "E:". I have no idea why it cannot locate anything it looks for and why " E: " is not there if it needs that location as the phone is completely stock.
Did you flash the HOME-CSC or the normal CSC file? I too got into a bootloop after a factory reset from the recovery, so flashing with the CSC file could be useful I guess. Recovery checking for an update always happens for me and it goes to recovery normally after checking.
