Boot-Looped device. I'm willing to try anything at this point.

So before I get linked to a bunch of solutions, here's what I've tried so far as I do have fastboot access:
I've tried flashing the latest factory image from Google. Both manually from fastboot and with NRT, all to no avail. It shows the Google logo then reboots repeatedly. I've tried entering recovery to factory reset there after flashing, but the device won't get into recovery.
I've also tried this method, but I can't get the device to enter download mode. It shows that it's entering it for a moment when I plug it into my computer while holding volume up, but then reboots into the bootloop again.
There's one weird thing that should be noted that makes me think this is some weird software issue, and not a hardware failure. I let the device bootloop all night last night until the battery died. When I powered it on this morning it went all the way to the Android setup page where you select wifi, etc and go from there. However, when I plugged it in and kept going through setup, it rebooted and has been looping since. I've contacted Google and they're supposed to conference call me with LG to see what we can do. Do I have any options other than that? Thanks for any help.

From bootloader
fastboot erase cache
fastboot format cache
fastboot erase user
fastboot format user
BTW what exactly is happening when you say it doesn't enter recovery?

I choose reboot recovery from the fastboot menu and it just boot loops. It won't enter recovery.

what if you try
fastboot boot twrp.img

I've bootlooped so many times I don't know where to start.
So you flashed the factory IMG from your bootloader correct.
Fastboot -w will wipe without wiping system.
Then reflash your whole system. I would redownload from the Google site through Skipsoft...the easiest way. When it asks to keep or flash new recovery you want to flash the stock recovery.

You'll have to reroot afterwards which you can also do through skipsoft.
Profit... Thank me if I helped.

It's a Hardware issue. Installing system again will not fix it. Send it to LG for a repair. My phone had the same issue.

Phone unconsciously bricked

Hi,
A few days ago I woke up with battery at 1% asking to enter extreme mode and after I did some charging I noticed my battery is draining fast. Then I decided to restart my phone and it went into a bootloop.
I restarted this phone previously without any problems.
Now I can't enter download or recovery mode. I can only use fastboot on bootloader menu but not adb cause I can't enter download mode (adb shows no devices but fastboot shows).
My phone bootloader is locked, S-oFF production. Everything is stock, never changed anything.
Tried fastboot oem rebootRUU didnt work.
Tried fastboot boot recovery.img and failed as I need unlocked bootloader
fastboot oem unlock/lock shows unknown command
fastboot flash hosp hosp.img also didn't work
fastboot flash boot recovery.img didn't work.
All of them lead to a small HTC logo in the middle but then return to the bootloop.
I also tried removing SD card and rebooting but didn't work.
Is there any solution to this problem? Thanks.

A wild shot..

Have you tried a "Power Off" ... wait 10 to 20 secs ... then hold "vol down" and "power" at same time. See the little "HTC" twice before you release the buttons. That should put you in boot loader mode. Then we can go from there. If it doesn't then I don't know what to do. It is how I have recovered from my catastrophes... and I have had similar instances like yours.

In need of some backup

Problem:
Unlocked phone is seemingly stuck in bootloop. Need guidance fixing it.
Explanation:
Hey guys,
I bought a used Nokia 6 (2018) and want to install a custom ROM on it. Last year, I used the paid service to have it unlocked - worked like a charm! So thanks again for that! After reading up on the topic, I set up drivers, adb and fastboot on my PC (Win10). I used
fastboot erase cache
fastboot erase userdata
fastboot erase boot
fastboot erase system​to prepare the phone and then
fastboot boot twrp-3.3.1-1-PL2.img​to get into TWRP. Next is where I ****ed up I think.
I followed a guide and moved twrp-installer-3.3.1-0-PL2.zip on to my SD card. In TWRP, I chose "install" and then picked said installer. After that, I chose the option to reboot.
That must have been the wrong thing to do, because now the phone only boots into download mode. When I hold the power button it does not shut down, but instead instantly reboots into download mode.
When I type
fastboot devices​I still get
PL2GAR9811701240 fastboot​and Windows plays the "connect" sound, when I plug it in. Yet all fastboot commands (boot, flash, reboot) now return
FAILED (Write to device failed (Unknown error))​What can I do at this point? Can I somehow revert to stock? How is that done? Can I use this guide and the linked stock ROM?
If you'd like more information, just ask away. I'm glad for any guidance at this point, so thanks in advance for your help!

Stuck in Fastboot

Hi all,
I'm a bit stuck. Went to sleep last night with a working phone. Woke up this morning with the device turned off, and trying to turn it on always bumps me into Fastboot. I'm guessing my custom ROM tried and failed to update overnight...?
I can run fastboot commands, but trying to boot using a boot.img from a downloaded ROM (fastboot boot boot.img) still kicks me into Fastboot. Tried installing a Stock ROM, and the full install goes through, but still reboots to Fastboot.
I've downloaded the MSM tool and EDL package to see if I can get that to work, but you guessed it, I can't get into EDF mode (holding both vol buttons and connectting the phone sends me to Fastboot).
Anyone any ideas
Arran

In my case I fixed it by swapping to the other slot...
getvar current-slot to see the active partition
fastboot --set-active=a to set partition a instead.
Rebooted - all OK

Can I recover data from a Oneplus 7t phone with locked bootloader?

I restarted my phone after being prompted to by a recent update. For a while the phone was stuck in a loop of booting to the android screen followed by the magenta tmobile screen before starting the process again over the course of 5 min.
Now the phone only boots into the recovery mode menu(?). The black screen with the oneplus logo that prompts you to pick a language before giving you the options of "view boot reason", "wipe data and cache", "advanced", and "exit" on the next screen.
View boot reason just says init_user0 failed.
I have wiped the cache and restarted, still boots into the recovery menu regardless.
I can boot into fastboot, but I do not have the bootloader unlocked. With the bootloader locked that means I cannot boot twrp recovery image from what I understand? And then unlocking the bootloader wipes the data.
I have managed to boot into EDL mode as well and the phone will show up as connected in the MSMDownload tool.
ADB does not work as far as I know since my phone no longer boots into android. (It displays the qualcomm snapdragon logo briefly before showing the aforementioned recovery menu).
Is there anything I can do recover my data given the above information? I have reached out to oneplus support as well and they said they'd get a more specialized person to reply to my case in 6-7 hours. Thanks for any help.

Correct.
Also from what I understand, you cannot 'pull' files from internal storage from Fastboot mode, contrary to ADB mode (unless I am wrong).
Maybe you could try switching 'Active Slots' in Fastboot mode? With a little luck the other slot may still be bootable. It is not clear if this command will be permitted with stock ROM. You can do a little research but the fastboot commands should be:
fastboot getvar current-slot
fastboot set_active a (or b depending)
fastboot reboot

Thanks for the info. I gave that a shot after and unfortunately it said Slot change is not allowed in lock state. Oneplus support did get back to me and said I'd have to send the phone in for repair. They said the device data is likely lost though so I'm not sure if it's worth sending it in vs just wiping and all that myself.
