Can I backup my phone or install TWRP recovery while stuck in Lineage OS recovery?

Highly unfortunately for me, I had thought it was a great idea not to make any backups when going to test if I was properly able to upgrade/downgrade Lineage OS versions. I had replaced my TWRP recovery with Lineage OS’s recovery, and then I “upgraded” to the same Lineage OS version I had currently been running, and my phone ran into a boot loop (The never-ending Lineage OS bootup screen). I believe I ran into this boot loop because I might have previously accidentally installed TWRP’s “system” app, and this would have been a problem due to LineageOS’s enforcement of priv-app whitelisting rules.

My device is a: LG H830

What I do have: Root, an unlocked bootloader, ADB/Fastboot, the TWRP recovery file

I believe I am screwed and that there’s no way out of this except just factory resetting/formatting everything. If I was correct in my research, my phone model blocks all fastboot commands, excluding bootloader + “unlock” related commands, and as a result, I don’t believe I am able to do a backup using ADB (I tried adb backup -all and it didn’t work). Lineage OS recovery has no way of backing up files, and I don’t believe it is possible to use it to flash TWRP recovery. All I need to be able to do is to save/backup my photos (Which are located in my internal storage). I think it is highly probable that I have finally entered into a hole that I can’t get out of. However, if anyone has any ideas about what I could do to either back up what’s on my phone (Mainly photos/internal storage if possible) or to flash TWRP without resetting/formatting everything, it would be substantially appreciated. Thank you!

Sources I checked out:

Team Win Recovery Project for the LG G5 – Post indicates that LG G5 H830 has flashing locked

Backup & Restore Android with ADB – Backing up via ADB would have worked if I was able to successfully boot into Lineage OS and approve the backup operation, but I can’t because I am limited to being able to boot in everything except system

Does Lineage Recovery have backup? – This is a post with answer(s) that designate the fact that Lineage OS’s recovery isn’t able to backup

storage – Is it possible to backup data from a locked android phone?

is it possible to get files from a locked android phone with PC ? I searched the entire internet but couldn’t get any reliable source. Although i can simply hard reset the phone to bypass the lock, but the data inside is really important to me. I want to try adb command to remove the pin lock but unfortunately i didn’t turn on the usb debugging .. Anyone have any ideas on this?

Info
My phone model: Vivo 7 Plus
USB debugging: Not turned on

debian – What’s the easiest way to automate a mongodb backup?

So, I’m almost finished building my first major production web app, and am wondering how to manage backups.

Weekly cold snapshot backups via my vps online admin seem ideal – but daily downtime sounds awful for UX. Hot backups seem pointless as they cannot be trusted to not be corrupt

Perhaps I don’t need weekly snapshots – just a single one, when the server is fully set up? Of course the code will be versioned in the repo.

My server runs Debian.

Is there a way to SSH in and clone the filesystem on my local machine, before encrypting with Veracrypt, before mailing it off-site?

I suppose I don’t need to backup the entire fs on a daily basis, but definitely Mongodb.

rooting – Is there a way to backup Samsung’s OneUI configuration?

I recently set up the home screen and app drawer of my Samsung Galaxy A70. The apps in my app drawer are organised into folders, some apps are hidden and some default apps are disabled. My home screen is completely empty.
I would like to switch to a new Samsung phone and automate the process of setting up the home screen and app drawer. Is there a way to backup my OneUI configuration? Can I find the OneUI configuration files (or something similar) somewhere on my phone? I am open to rooting the phone.

backup – Is `SharedPrefs` saved when android:allowBackup=”false” ? How do we encrypt it?

I’m confused with the documentation whether the SharedPreferences are automatically created for an app, even when android:allowBackup is set to false.

Is it possible that they’re stored even when we explicitly disable the backup?
And if yes, is it possible somehow to encrypt these data?
