Can't get into recovery mode,Phone stuck at oneplus logo-Help me please

I decided to reflash TWRP using Fastboot (Yes, it did show up in Fastboot), and I was able to flash it using:
fastboot flash recovery twrp.img
But when I tried to boot from it using: fastboot boot twrp.img
I get the following error:
C:\adb>fastboot flash recovery twrp.img

Hmmmm...i don't think you can't reboot into recovery using fastboot command...you need to use power button + volume down to reboot into recovery manually....

re-flash the recovery and don't forget to use this command after flashing recovery....
Code:
fastboot format cache
then reboot to recovery manually....

I have exactly the same problem except I still have a working OS.
After I couldn't boot into recovery I tried to flash a new recovery by using the TWRP app ("flashed successfully"), reboot to the recovery... same thing, it's stuck at the logo. I tried the flashify app as well (flashed successfully)... reboot... same thing.
I also tried to format the cache in fastboot after flashing the recovery which didn't help.
So either I am stuck with this ROM for the rest of my OPOs live or someone can help me.
I am by no means new to flashing. I flash new ROMs since my HTC Desire, I flashed my SGS3 on a weekly basis and I own my OPO since it came out and I never had any problems.

if you don't have ROM installed you can manually flash a a rom from fastboot.

Root: Stuck at "Your device is booting now"

Hello! I tried to root my Honor 6x (BLN-L21, EMUI 5.0) following the instructions there:
cyberkey.in/how-to-root-honor-6x-100-working/
The bootloader was successfully unlocked.
But when I tried to flash TWRP the process failed and now my phone is stuck on boot :
"Your device has been unlocked and can't be trusted [...] Your device is booting now."
I can get access to recovery and fastboot. I wiped the cache and tried a factory reset but nothing changed, my system won't start and I don't know what to do.
Please help!

if you have the boot backup then restore it.

I don't have any backup. Is there a way to just reset everything? Also I don't know how to connect to the phone anymore since adb won't find the device.

if you cannot find the boot.img
just do a rollback bro
here is the link
first dload this

I think that I flashed the wrong files in "boot" and "recovery". Please tell me which files I should flash there.
I used the commands:
.\fastboot flash boot twrp.img
.\fastboot flash recovery twrp.img

The guide from "cyberkey.in/how-to-root-honor-6x-100-working/" is simply wrong when it comes to flashing the twrp recovery. If you really followed this guide completely then you flashed the recovery to the boot partition.
Use "fastboot flash recovery twrp.img" to flash the recovery.
You will still have to flash the boot image to your boot partition then (fastboot flash boot boot.img).

Use fastboot flash recovery twrpname.img to flash the recovery

Ok so basically I need to flash the boot image. However I don't know where to find the stock boot image. I downloaded the so-called "full version" of the stock firmware that I found here: boycracked.com/2017/07/20/official-huawei-honor-6x-bln-l21-berlin-l21-stock-rom-firmware/
However there was no boot.img file inside.
If you could direct me to the proper stock boot.img or send me one, that would greatly help. I had EMUI 5.0 with Nougat 7.0 I believe, phone version BLN-L21.

Thanks. I successfully updated boot.img and and recovery.img, but system won't load, so I might have imported from the wrong STOCK version.
I tried to reinstall a stock ROM using:
fastboot flash system system.img
But I got this error message:
target reported max download size of 471859200 bytes
sending sparse 'system' (444686 KB)...
OKAY [ 12.901s]
writing 'system'...
FAILED (remote: sparse flash write failure)

Then I tried to erase the system file with "erase system" and got this error:
erasing 'system'...
FAILED (remote: Command not allowed)
finished. total time: 0.013s
I guess that the only option now is to install the files on an external SD card?

I recommend you to download firmware files only from the official honor website or by using the huawei firmware finder(https://forum.xda-developers.com/tools/general/huawei-firmware-finder-team-mt-t3469146)
In this case try to use huawei firmware finder to get the right stock version for your phone. Download these two files: e.g. update.zip & update_full_BLN-L21_hw_eu.zip.
Export the following image files: recovery, system, boot and cust.
The try to flash them:
fastboot flash boot boot.img
fastboot flash system system.img
fastboot flash cust cust.img
fastboot flash recovery recovery.img
If flashing a partition via fastboot fails then it is usually because it's the wrong image or just not made for your phone.

Thank you guys, you saved my phone! I eventually managed to flash the files from Nougat update for European Honor 6X BLN-L21C432B360 that I found there: stechguide.com/honor-6x-b360-nougat-update/
Now the phone is working fine.

Hello, could you be more specific about your problem? I'll be able to help you.
Brief Explanation:
From the screen on which you're stuck, press and hold power button for about 10 seconds to forcibly restart your device. when you see the same screen again, immediately press and hold volume up button(for about 3 seconds) to boot to eRecovery.
> Choose shut down option on eRecovery. press and hold vol down button and insert the charging cable to boot to fastboot.
> Press and hold power and volume up button to boot to recovery. (You could do this even from fastboot screen and the screen you're stuck at).

Failed to load/authenticate boot image:

Need some help here as I am in a bit of a bind. Was on 5.1.11 and attempted to update to stable Pie. Used Blu_Spark TWRP v2 and upon rebooting got the error about device being corrupted. Continued booting but was stuck on boot animation. Rebooted to TWRP and attempted to restore nandroid. Upon restoring and reboot, boots immediately to TWRP. Attempt to change slots (which might have been an error on my part) and rebooted. Now stuck in fastboot! I attempt to flash TWRP.img via fastboot and get the following error:
Code:
PS D:\OnePlus 6\adb> fastboot boot twrp-3.2.1-0-enchilada_official.img
downloading 'boot.img'...
OKAY [ 0.628s]
booting...
FAILED (remote: Failed to load/authenticate boot image: Load Error)

If I try and switch to slot _b, I get the following error:
Code:
PS D:\OnePlus 6\adb> fastboot --set-active=_b
C:\Android\fastboot.exe: unknown option -- set-active=_b
PS D:\OnePlus 6\adb>
At the moment, my phone is bricked, so any help is GREATLY appreciated.
Thanks!!!!

I had the same, fixed it using this: https://forum.xda-developers.com/oneplus-6/how-to/rom-stock-fastboot-roms-oneplus-6-t3796665
Choose the Andriod PIE fastboot rom.
After that you can boot into PIE again, and if you want to go back to Oreo, use this Rollback procedure

Stuck in fastboot after using fastboot rom

One plus 7 pro, European version
So i was running Lineage OS on my phone for some time now (latest base update i did was to ob1 as far as i am aware), when there was an update lately
I installed it as normal, but the phone would not get past the boot animation and kept restarting, so i went back to the other slot to see if that still worked, but it only had a laggy boot animation, which never booted
I then installed the previous version that i was running before the update back to the other slot, hoping it would solve the problem of not booting (that worked before already) but it still did not boot
I saw someone post they had 10.3 installed as base so i restored the ob1 installation with a fastboot rom i still had on my hard drive, but upon finishing the phone just went into crash dump mode showing
dm-verity device corrupted force dump
kernel_restart
I tried another install just to be sure, but same result
I then tried flashing twrp to the boot partition to at least get there, but the phone just went straight to fastboot upon doing that
Fastboot boot still seems broken and just shows
D:\Minimal ADB and Fastboot>fastboot boot tw.img
downloading 'boot.img'...
OKAY [ 1.228s]
booting...
FAILED (remote: Failed to load/authenticate boot image: Load Error)
finished. total time: 1.346s
I searched around if there were other ways to install twrp from fastboot, and found this tool (https://forum.xda-developers.com/an...g/apk-img-dat-br-one-click-decompile-t3886057) that promises to unpack and repack the boot.img, so i hoped i could use that to manually add twrp to it, but it failed to unpack the file
Next thing i found was this MSM tool post (https://forum.xda-developers.com/oneplus-7-pro/how-to/msm-tool-guac-t3934691) instructed to hold volume up and down for 5 seconds before connecting the phone to a pc, and the program actually picked it up, however the phone started itself after a few seconds and went back to crashdump mode
At this point i'm seriously out of ideas, does anyone else have other ideas that i missed?
Does anyone have a boot img with twrp?

keep trying the MSM tool. it WILL work.
if you can get into fastboot again, type in fastboot reboot edl in ADB

This is indeed what typically shows for an error when fastboot boot isn't working. Probably due to using an older fastboot ROM. I'd try to use a newer fastboot ROM, or you can flash a patched boot image, which is how the phone was being rooted before fastboot boot was fixed:
https://forum.xda-developers.com/on...isk-patched-boot-image-oneplus-7-pro-t3964345

If I recall correctly, you can't fastboot boot with android 10.

Wiped OS, cannot process past bootloader

I wiped my OS and was having issues installing a custom ROM through TWRP. My phone rebooted and now I'm stuck in the bootloader and unable to get back into TWRP. I've tried using fastboot, but that also fails:
Code:
~\Downloads\TWRP>fastboot boot twrp-3.5.2_9-0-enchilada.img
Sending 'boot.img' (32604 KB) OKAY [ 0.823s]
Booting FAILED (remote: 'Failed to load/authenticate boot image: Load Error')
fastboot: error: Command failed
Is there some way I can recover (even if back to stock), or am I screwed?
Thanks

You can revive any ROM mate. All you need is patience and a small knowledge in debugging the error.
If you are stuck on Bootloader. Try flashing rom on both slots from bootloader directly
Below link has process to do so
[ROM][STOCK][FASTBOOT][OP6] Stock Fastboot ROMs for OnePlus 6
Things are changing with the advent of project treble and seamless updates. OnePlus will no longer release ROMs flashable via stock recovery (with twrp is possible but not recommended). The updates will be done on the slot not used for example...
forum.xda-developers.com
If you can boot to recovery, try flashing roms directly by downloading stock roms. If you get stuck, try postng error message with screenshot using another mobile.
