Problems booting into recovery

Okay, to start with, I've read the other threads about this. I understand the process that *should* work:
1. Power off.
2. Then, press and hold both all Volume Down + Power buttons at the same time until the LG Logo is being displayed on your LG V20.
3. Now, release the keys and press the above combination again however, this time you should wait until recovery mode menu is displayed.
...and I've tried the version where you keep holding the Volume Down button the entire time.
So, yes, I've reached the white screen where it asks you if you want to do a factory reset. I've hit "Yes" to both questions. The problem is that it really does a factory reset then.
---
After unlocking the bootloader, I installed TWRP via fastboot:
adb reboot bootloader
fastboot flash recovery twrp.img
fastboot reboot
...everything went fine.
But I can't get into recovery. And since I'm waiting to have TWRP working so that I can flash root, I can't boot into recovery via an app.
What did I do wrong?
EDIT:
Okay, it looks like TWRP isn't working properly. I tried "adb reboot recovery" and that got me to a dead Android icon and a "No command" message. I have no idea why TWRP isn't working.

to confirm, have you verified you are using the correct TWRP version for your V20?
in this step "fastboot flash recovery twrp.img" is your twrp image that you saved, named twrp.img? If its not, that command won't work correctly.
usually after I flash recovery, when still in the recovery menu, i choose reboot recovery just to make sure it did stick. If it reboots back to itself, then try rebooting the device, and again confirm with manually entering recovery. Maybe overkill but it works for me LOL.
Good luck!

I am in need of big help! I made a critical error after days of trying to navigate the minefields of rooting my device. I have a LG V20 h910 and it is no one-click wonder root. It made me work for it and I finally got it. I loaded LineageOS 14.1 and all was good until the USB OTG cable from my PS4 controller did not register anymore. Damn, that was a let down, and probably led to my careless move of needing to downgrade my TWRP, saw the version I needed, forgot these are device specific, and now I'm stuck in a hard place.
Perhaps the fix is easy, but I have not found the answer after many, many searches...
I had TWRP 3.2.1-2 and needed to downgrade to 3.2.1-0 to try SuperRom (hoping it would have OTG ability). I hastily grabbed the first TWRP 3.2.1-0, threw it on the SD card, wiped everything except internal storage, and flashed the img, and did a reboot. Road block went up.
I tried getting back into recovery, did the PWR and DOWN pressing combo and got the Factory Reset screen, but after clicking "Yes" to both, instead of getting the TWRP screen, I got this error screen (attached).
I tried another idea - hooked it up USB to my PC and tried accessing it via adb/fastboot. I tried multiple drivers for my device, but no adb and no fastboot devices were ever found. The only thing that almost worked was booting phone into FASTBOOT mode by holding DOWN btn and plugging in a USB cable attached to PC. Once in FASTBOOT mode, My PC at least saw the ID for fastboot device. I tried to flash TWRP via fastboot, and it looked like it would happen, but in the end there was no phone screen response to my attempt, and the cmd window on my PC would get stuck and just hang.
Can someone please advise me on how I can fix this problem?

phone bricked? help!

I decided to update my old oneplus 2 to lineageos 15.1 with, but when I tried to flash the file with TWRP, it shows an error. Since the TWRP version I was using was old, I decided to update it first. Keep in mind at this point i had completely wiped my device. So, I downloaded the "twrp-3.2.1-0-kenzo.img" file, as per a youtube video where the dude managed to flash the update successfully, and gave it a go. It showed up as successful. Then i shut the whole device off, and tried to boot back in to recovery to flash the ROM again, but the thing won't boot. It's stuck on this boot screen (with the oneplus logo and 'powered by android' at the bottom), and refuses to go further. I'm stuck in a situation with the phone having no OS, no recovery and the thing won't show up when I connect it to the pc either. Well, the pc makes the 'device connected' notification sound when I plug it in, but nothing shows up on the file explorer or the device manager.
That's my dilemma, please i need help!
Thanks in advance.

You downloaded the KENZO (this is not oneplus2! ) TWRP and flashed it on another phone (oneplus2), just normal that it doesn't work and your phone is messed up.
If you can enter fastboot (vol up and power button to boot) you can rescue your phone:
-enter fastboot (vol up + power, while phone is completely off, u can also hold it until you can see "fastboot" written on the screen)
-connect device to a computer with fastboot installed
-type "fastboot oem unlock" into a terminal/cmd window if there is no error, you are good to go, otherwise your bootloader relocked, use this thread to recover
-if your bootloader is still unlocked, download the ONEPLUS2 TWRP IMG, ALWAYS make sure to only flash the roms, kernels, recoveries or zips for YOUR phone otherwise you can really DESTROY your phone!
-now type into terminal/cmd: "fastboot flash recovery *drag the oneplus2 twrp image into terminal/cmd window* and hit enter
-use vol down + power to reboot phone into recovery and wipe all partitions
-Install a ONEPLUS2 ROM of your choice
If something is not clear, use google, because this is most likely basic stuff you have to know when flashing your phone

I can in fact go to fastboot mode by holding the power+volume up keys. When I the phone to my pc it does show a fastboot device (9597b869 fastboot). What do i do from here?

i tried to follow the guide. but the bootloader, as per you description is relocked. the download link for the driver you provided shows up as empty/no longer available. that's where i'm getting stuck.
P.S, i can enter fastboot mode on the phone via power+volume up.
thanks for the help so far, i can't seem to find much help other than from you so far

Oh, the link is dead, sry for that. try this one (GDrive links are up and working).

so i managed to get into qualcomm mode, updated the drivers, and ran "MSM8994DownloadTool.exe" in administrator mode. it went as it's outlined in your guide. however, at the end of that process, the phone got stuck in a bootloop (the oneplus logo flashes for a moment and restarts). and can't get into qualcomm mode now, since when i connect the usb to the pc while the phone off, it lights the display (to show that it's charging, i think). any way back from this?
(i can still get into fastboot mode)

Do you still have TWRP? If yes go to TWRP and shut down the phone there, afterwards you should be able to enter qualcomm mode again.
otherwise you have to try (i think 10s power button will shut the device completely down). You should be able to enter qualcomm mode if the device is fully shut off (your scenario sounds as if the device is not fully shut off when u connect it to the pc).
Just to go sure: You are absolutely sure to have a oneplus2, are you?

Stuck with no ROM

Uninstalled magisk and the screen is black, only vibrates when pressing power button or the right side of the screen. I don't even know how to turn off the phone. I was able to do it because the warning of the bootloader being unlocked appears. How I can flash stock rom? abd won't recognize the phone.
I saw https://forum.xda-developers.com/oneplus-6t/how-to/tool-6t-msmdownloadtool-v4-0-oos-9-0-5-t3867448 this while searching but I'm scared since it locks the bootloader after.
Thank you

Can you get into fastboot? Hold down both volume buttons together and see if you can force your device into fastboot mode. Then from there, get the TWRP img file and use fastboot to boot the image, then flash the stock OOS rom, either from TWRP install option or with adb sideload of you're comfortable doing that.

I can, could you link me to a tutorial how to boot the image? I got it already, but unsure of how to proceed. Many thanks!
edit: now when I connect it to the PC it stays on the warning that the boot loader is unlocked

Now I was able to start TWRP but I still don't know how to send the file to the phone;
ADB recognizes the phone when TWRP is running
I think it's solved, thanks a bunch!

Oneplus 8 pro bricked sort of but can't seem to find an option to revert it

I was having issues with the android 11 so thought to downgrade. Since the system wouldn't allow me to do it from the local storage, I thought I will just install TWRP and then flash the OS that way but in the process, I don't know what went wrong but fastboot will flash the recovery but when I tried to boot to it with the command it put me to Qualcomm crash dump mode. I downloaded the MSM Tool as I have gone through this process before but for the millionth time, I just can't put my phone to EDL mode. Every time I try with the volume up+volume down, keep pressing it until I plug the cable into it, the phone just goes to fastboot mode.
TL;DR - only have access to fastboot, no recovery, can't even install recovery because of crashdump issue. Phone not entering into EDL mode tried pushing it from fastboot to EDL using commands but doesn't work. Since it is at fastboot every time, device manager sees it as android bootloader platform. Device manager sees it as Qualcomm HS-USB Diagnostics 900E.
I've almost tried everything and I know device manager is supposed to see the device as 9008 for the MSM tool to work but it is NOT GOING INTO EDL MODE!!!!!
*sigh* any help will be really appreciated guys. Thank you.

ok but how do I flash my stock recovery back?
since the only thing I can access is fastboot mode, I tried flashing a stock fastboot rom but that clearly states that it cant be used to downgrade and currently there are no android 11 fastboot rom available so now what am I supposed to do wait?

I just did this. So what I did was since there were fastboot stock roms available but not for android 11, I downloaded one...ran it through payload dumper and copied these files to overwrite the one from 10.5.13. But when I did that and everything went 100% as it should. My phone was not turning on now...no response on button presses and no sound when connected to computer...I thought did I really became the first one to hardbrick a oneplus....then I just checked in device manager and it was showing as 9008 at the end..which meant it is EDL mode...that was exactly what I wanted. I immediately started MSM Tool and there it was then I just started and now my phone is back to normal along woth having OOS 10.5.13 exactly what I wanted so thank you for pointing my foolish mistake.

Just replying here because this was the only google result when searching the error messages. I could only get into fastboot, no edl, and recovery gave the error message about download mode. I noticed when holding both buttons down and plugging in it would come up as the Qualcomm USB thing 9008, but every 10s it would reboot again and if I wasn't holding the keys go into fastboot. The solution was...
Have the MSM tool started and ready
In the 5-10s you have while the device shows as Qualcomm USB (QUSB 9008 something) hit the start button
This kept it in that mode and although the screen never showed anything it went through the 300s restore and I was back to stock.

Bare in mind that EDL mode doesn't last very long (least it didn't for me)
So make sure you're ready to press start on MSM, once the process has initialized it'll keep it in that mode.
Found it out by trial and error. I too thought I couldn't get into EDL but it's probably the last thing that would fail on the phone, if fast boot is working then EDL almost certainly is too.

Unable to boot into newly-flashed recovery from fastboot (LineageOS 18.1)

Recently got a hold on the T-Mobile version of the OnePlus 6T. Already have a OnePlus5 running LineageOS as well and thought the installation would go as smooth.
Following these directions, I got through unlocking the bootloader (with the unlock_code.bin from OnePlus) and I thought I'd gone through flashing a custom recovery. I was able to boot into fastboot, ran # fastboot flash boot lineage-18.1-20210506-recovery-fajita.img, and shutoff the device. Now I'm stuck in a bootloop at the screen indicating that the device has been unlocked and data can't be verified.
While still connected to my PC, any combination of Power + Volume keys will flash the display and instantly go back to the bootload screen. The only way to shut-off the phone is to disconnect it and do either Power + Volume Up or Power + Volume Up + Volume Down; Power + Volume Down to try and boot into recovery does nothing. Plugging in the phone while off auto-starts it back to the bootload loop.
I can turn on the phone while disconnected, but the only way to escape the bootload loop is to boot straight into fastboot with Power + Volume Up + Volume Down. From here I can connect it to the computer and it's seen as a fastboot device. From here, however, any of the options will reboot into the bootloop.
Is there anything I can do from here? It's not a hard-brick, but I'm not sure why I'm stuck in a loop. The flashing of the recovery seems to have worked, no issues with A/B as stated could happen in the docs. I'm at a loss.
Code:
Sending 'boot_a' (65536 KB) OKAY [ 1.573s]
Writing 'boot_a' OKAY [ 0.365s]
Finished. Total time: 1.947s

Data can't be verified? It does let you run fastboot commands, just not send files?
Most people on this device use TWRP. I have a guide here.

Yes, I can get the fastboot menu, but trying to boot from the lineage recovery image would take me straight to the warning page indicating the device is unlocked and to not store confidential data.
I just tried using the guide you posted to go with TWRP, but I'm having issues again with booting the recovery. Followed every step: downloaded the ROMs, flashed them all to the phone as per your script, was able to boot, chose the language and wiped, and once in the phone rebooted into the bootloader. But similar to before, I run # fastboot boot twrp-3.5.2_9-0-fajita.img, but now the phone seems to be stuck on the OnePlus logo with the words Fastboot Mode underneath.

You may need to start over. I the unfortunate part here is the TMobile 6T is a bit different and complicates things. Recent TMobile MSM Tools have been posted in the TMobile thread, they just aren't in the OP. I'll be honest I don't follow the TMobile devices, so I don't know much about what's best to use between versions and international tools and what not. There are a few TMobile users that posted in my Guide thread that you may want to tag and see if they can help?
