Stuck in fastboot - LG G7 ThinQ Questions & Answers

Successfully unlocked bootloader, tried flashing a custom ROM (DanCS1995 Lineage 19.1), OFOX was successful, ROM would not load however, instead it booted to a decryption failed messaged. I followed the guide to the letter. So, I followed the unbrick guide (https://forum.xda-developers.com/t/...ewer-lg-phones-from-edl-or-9008-mode.4213851/), successfully flashed the latest stock KDZ via LGUP but nothing happens, it just boots right back into fastboot. I tried a couple different KDZ's. I tried switching between slot A and slot B and now I cant even boot into OFOX recovery as KDZ reflash overwrote it. I'm going in circles and looking for ideas.

Just to clarify,
Bootloader - Unlocked
Fastboot - Working?
DL mode - Working

Also if I try to fastboot boot into OFOX now the device just freezes at the LG G7 ThinQ splash screen.

Flashed KDZ, Stuck on LG Logo

Hi guys, earlier today my phone just decided to randomly reboot itself. Since then it was stuck in a boot loop. I couldn't get into recovery mode at all. So instead, I got into the firmware update mode, and flashed a Marshmallow KDZ using LGUP. First I did and update, but that didn't work. Then tried refurbish, and that failed too. It just doesn't want to reboot. Any ideas?
Any way to install TWRP from the firmware update (download mode) screen?
Does fastboot command work? If it does simply run fastboot boot yourtwrpimagename

Stuck in Fastboot bootloop

I fumbled trying to flash a custom rom. I forgot to do the step where I unlock the bootloader. Now my phone is currently stuck on fastboot. If I choose the option to boot normally, my phone retarts and I am again in fastboot mode.
My goal here is to flash CM 13. Is this still possible? How can I get my phone to at least boot properly into recovery mode (it is rooted).
Fastboot flash stock recovery.
It worked. Thank you! I also went through all the steps again and have successfully installed a custom rom.

Semi-bricked XA1, possible recovery?

So my phone has been lagging a whole lot using the stock rom and I have decided that I'll try a custom rom to see if that changes anything. So I came here and saw this forum:
"https://forum.xda-developers.com/xa1/development/half-gsi-oreo-8-1-t3902259"
I thought I'll try and so I unlocked my bootloader, only to have my phone be reset (not a problem, everything was backed up). It also boots with a warning "Device unlocked and can't be trusted".
Then I went on to download TWRP using this link in that post: "https://mega.nz/#!FQFXCYSY!DgxQRkaY1Eqq3B0fZLEQBNzUs0Zj80L6IzSHxdorQ3A" which is the TWRP 3.3.0.0 V2 IS FOR ALL USERS.
I didn't want to flash in the event it was the wrong recovery so I tried booting into it, fastboot boot recovery.img
It flashed, everything was ok and now the phone doesn't boot. It stayed in a boot loop. I went ahead and flashed recovery this time, no luck. Downloaded a recovery.img from another website and it didn't allow me to boot to android or recovery.
Is there a way to save my phone, I can't get another phone until August due to contract. It can still boot to fastboot and gets stuck when trying to boot to android. It being able to boot to fastboot makes me think theres a chance to flash a stock rom or any custom recovery and rom to get the phone working again. Any help? Thanks!

OK use the boot.img and recovery.img made by @janjan HERE. Under the heading ¨Downloads¨ see ¨Xperia XA1¨ and download the KERNEL + RECOVERY the boot.img and recovery.img are compatible with the G3121-G3112-G3125-G3116-G3123 devices on the applicable firmware.
Flash BOTH using fastboot. The boot.img is patched to allow TWRP to boot which it will never do using the stock boot.
If you wish to go back to stock then simply use FlashTool to flash the stock fotakernel.sin and boot.sin contained in the firmware for your device.
Does it works becouse I boot my g3116 from flashtool camand was
Fastboot boot boot.img and then also it's stuck into bootloader

Stucked at Fastboot Mode

I was in realme UI 2.0, I wanted to downgrade it into RUI 1.0.
So I downloaded rmx1931 c27.ofp fastboot rom and tried flashing it using realme flashtool.
it failed several time and sometime showed flashed successful but didn't bootup, keep booting into fastboot mode.
I tried to get into recovery but it also boot into flastboot mode again, then I tried flash twrp and orangefox using cmd menu. everything flashed successfully but doesn't work. I tried flashing vbmeta also, it doesn't work either.
How can I fix this now?
Someone help me Please.

Fastboot loop help... Sprint SOL?

I was doing the whole shebang, got my bootloader unlocked via QFIL and installed ArrowOS successfully, somewhere along the way I went wrong when flashing magisck, now I'm bootlooping in fastboot.
I can access Fastboot and flash the recovery that shows you which slot you're in via QFIL, but I can't go any further. I have backups of my abl and my boot, and my custom magisk IMG .
Can I fix this or do I throw it away?
