Fastboot loop help... Sprint SOL? - LG G8 Questions & Answers

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?

Flashing OTA failed. I need help to restore my phone.

Hi,
My phone is rooted and the DPI was customized. I tried to manually flash the OTA but the installation got stuck so I cannot boot into Android anymore. I tried those restore tutorials but when I try to flash using fastboot I get a "FAILED (remote: Permission denied). I tried to clear the cache in the recovery and then it got also stuck and now I can't access recovery.
This is what I can read in the bootloader
---------------------------
FASTBOOT MODE
PRODUCT_NAME - Z00A
VARIANT - ASUS_Z00A
HW_VERSION -
BOOTLOADER VERSION - unknown
IFWI - 0094.0177
SERIAL NUMBER - Xxxxx....
SIGNING - ?
SECURE_BOOT - ?
continue fastboot process

I just been successful in installing TWRP recovery using the toolkit.
Edit: I installed the latest CM 13 build and it can't boot to Android. It goes straight to TWRP recovery no matter how I turn on the phone. My bootloader still looks the same.
Edit: I tried flashing a prerooted .img and stock recovery and I can go back to recovery but I still can't boot into Android or factory reset or nothing.... I'm desperate!

You may need to flash boot.img and droidboot.img for the same version of rom you flashed, ie. if you flashed 139 then you must flash the recovery, boot and droidboot images for 139...
As you found the pre-root rom files, download the whole file and flash these image files too making sure you use the right commands or you will brick your phone...
fastboot flash recovery recovery.img
fastboot flash boot boot.img
fastboot flash fastboot droidboot.img
fastboot flash system system.img
Just remember, flashing these partitions can, potentially, brick your phone. You do this at your own risk...
Happy flashing....

Thanks for your help. I did that earlier with the latest pre-rooted OTA and now it gets stuck on the splashscreen. I tried going to recovery (stock now) and doing a factory reset after flashing system.img and it still the splashscreen after I reboot. I know the 1st boot after flahing a ROM can be long, but now it's been an hour and I'm still on the splash screen...
The only other thing I can recommend is to flash a RAW rom image. As I have never needed to do this I can't say how this works but if you do a search you should find out the procedure...
This may relock your bootloader so just be aware....

Phone can boot into fastboot, and system but wont go into recovery

Hi guys i flashed the 3.5.3 CM today but i decided to go back with 3.26 again, so i followed a guide that tells me to install stock recovery over twrp before i install the rom but after i fastboot flash the recovery i cannot go into the recovery anymore.
i tried to flashed the modified twrp and then boot to recovery but still wont open it.
the phone works and can go into fastboot still but it just wont access recovery
anyway to fix it? sorry if this has been discussed before. im on a mac for more info
TIA

Is your OS booting?
yea
Got the same problem here. Can boot into system and fastboot but if boot to recovery i get the oneplus logo and the bootloaderscreen and then i get a black screen where i should get my recovery. And if wanna Force shutdown my oneplus it freezes somehow. I tried everything to fix this with no result. Stock recovery doesnt work too.
Hi I just had the same problem, I have sent it back to Oneplus for repair. According to the ticket, I had a faulty motherboard, which has been replaced. If you can, do it. I only had to wait for a week before it was sent back.
Had the same problem last night. Following method nr 2 in thos thread solved it.
http://forum.xda-developers.com/showthread.php?t=3405700
Sent from my ONEPLUS A3003 using XDA-Developers mobile app
using fastboot to wipe the recovery partition then fastboot flashing modified twrp twice worked for me, i think the oneplus recovery image thats doing the rounds doesn't want to play nice lol
If youre phone boots in to system, download Flashify from play, flash recovery.img (you need to extract .img file). Go to recovery to check if it works. If not try other recovery.
after flashing the community build i cant boot my device in fastboot mode, it wont start the recovery or boot the system sucessfully.

If your device is unlocked, flash the recovery.img from fastboot.
You can download TWRP for oneplus 3 from their site.
Rename the downloaded recovery to recovery.img.
And open fastboot in the path of the recovery image.
Use the command:
Code:
fastboot flash recovery recovery.img
Hopefully this helps

managed to fix it the other day, by flashing the modded twrp.. somehow that one worked after that i flashed the 3.26 plus the 3.26 modem ones because if i didnt, my touch screen wont work...
For me, I flashed the twrp from fastboot.
But still the 1+ logo shows when I try to boot in to recovery for 5 sec and shuts down with 2 dots of lights in the navigation button area
The normal boot is working fine. Did flash the recovery using apps like TWRP Manager, Flashify etc. It will show successfulll. But when I try to boot in to recovery, same result.
Please help

Unable to boot into TWRP

So, I successfully unlocked the bootloader, then followed the instructions to install TWRP (which worked initially because I was able to access TWRP immediately after flashing). But how to I access it again once I'm back in the OS? When I click reboot to recovery it always reverts back to the stock recovery. I'm still on the stock OS, but I just assumed once TWRP was installed I could boot into it from there. What am I missing?
Solved the problem by getting Magisk installed and using Flashify app to flash the downloaded TWRP img.
@brGabriel just use the fastboot commands as mentioned by manojpawarsj12;
fastboot flash recovery twrp.img
Don't mess around with Flashify, it's dated and a good way to brick your phone...

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

Stuck in fastboot

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.
