My OnePlus 8 Pro is stuck in a fastboot boot loop, can't even power the phone down at this point, fastboot just comes back up again. There is no ROM on the phone somehow (after attempting to downgrade from the beta program) The bootloader is also locked as well, and can't flash any fastboot images. I have attempted to use the MsmDownloadTool, but can't get out of fastboot to use it.
What can I do at this point?
UPDATE: After letting the phone sit and drain the battery completely, I was able to get it into EDL mode, and use the MSM tool, it flashed everything, but still no boot. Any suggestions?
Make sure that you are not connected to USB and select power off from the fastboot menu. You should be able to put it into EDL mode after that and connect back to USB so that you can use the msm tool.

Power off would immediately power back on and to fastboot. I let the phone die and was able to get it to go into EDL mode after, and was able to use the MSM tool, but still no boot.
Any suggestions?
Only time I have had that happen is when I still had the USB cable connected. If it let you use the msm tool and still no boot there may be something wrong with the phone and need an RMA.
Can you access fastboot from the command line? Try downloading the fastboot rom and flash it using the flash-all bat. I had an issue after doing an ota where it wouldn't boot anything but the bootloader. Had to manually change slots to B and then run flash-all and was good after that.

Fastboot does boot, but it is locked so there is no flashing anything through that.
Recovery can now boot as well, but still no boot to OS.

Cannot unlock as I can't boot into an OS to enable the unlock. Tried flashing through fastboot but gives error that it has to be unlocked. I have attempted unlocking it through fastboot but it gives an error that it can't be unlocked.

Rough. I was thinking since it didn't have a os loaded it would bypass that switch in dev options

Hey guys, I have a unlocked, rooted phone which i need to return to ZTE. I used miiflash to get back stock rom and recovery but need to lock the bootloader. Whenever I try to go into fastboot mode, the phone just sits in the "Please lock the bootloader" screen, but i can get into stock recvoery and the ROM starts.
Even using adb or stock recovery to go to fastboot doesnt work.
I used this package to flash stock:
ZTE_A2017UV1.1.0B32_FULL_EDL_PACKAGE_BY_TURKDEVS
Any ideas?

That's normal. I think there's a package called A2017U_FASTBOOT_UNLOCK_EDL somewhere over here (they got it from 4PDA). Flash it via MiFlash and it should slap a new bootloader there or something. After that you can lock it
Ok just to verify, i am on the B32 stock rom with the bootloader still unlocked using Miflash, i need to be very careful doing this as I have already bricked one phone this week (another thread is coming about that)
i should use this thread to go back to B29 then lock the bootloader?

I believe B32 doesn't let you access the Bootloader. You need to MiFlash B15 in edl. Then you'll be able to access the Bootloader and fastboot oem lock. But be patient it takes over 30 mins for it to completely flash the package. After you relock it then you can either ota back up, MiFlash B32 in edl, or install the official b32 zip from zte from the SD card.
Here's B15 edl package

Turn off your phone completely, then hold volume up, volume down and power at the same time. You'll see the LED flash red once and nothing on the screen. That means it's in EDL mode. Connect USB and your computer will recognize it and do as you wish

First time I downgrade from B35 to B29, then to B15. Took a while. 2nd time, I found a TWRP EDL file which gives you twrp and fastboot altogether. https://build.nethunter.com/misc/axon7/A2017U_B29_TWRP_EDL.zip
got an advanced replacement and I am unable to unlock the bootloader with the toolkit even after downgrading to B19.
OEM unlock is selected
I can't even get to recovery using vol+ and Power. it just vibrates and reboots when i try.
and i have an FTM mode i didn't have before.
EDIT:nevermind I did it manually.
Holy cow this thing came with TWRP on it?!?!?!?
OMG now it just sits at the linux penguin and I can't get to EDL only DFU
how can i flash the stock ROM in TWRP?
Edit:got it.
anybody know the command to run in twrp to make root settings stick?

No, you have to run the command through ADB. When your phone is on and unlocked, enable USB debugging, then:
'adb devices'
accept the connection (should prompt you)
'adb reboot disemmcwp'
Just remember: DISABLEEMMCWRITEPROTECTION
so now i got everything updated and back to "normal" but I can't enter fastboot so I can't flash twrp. If i go to the bootloader and choose fastboot it just reboots.
flashed twrp and now it s just the penguin
Back up and running

I used DrakenFX's guide to going to stock using TWRP.
One of my costumer V20 is now stuck in fastboot.
Whatever I do, it's keep coming back to fastboot mode.
I can enter download mode, and try flash , even using the costum LG up, with upgrade option, partition DL option.
I use Box ( octopus, Z3x ).
I don't know what is wrong with this phone.
it's only going back to fastboot.
Any help is really apreciated.
Thank You.

It goes back straight to fastboot after LG logo
If you can get into download mode try the 'upgrade' option in lgup
It is stuck in fastboot because your customer tried to root it with lafsploit without unlocking the bootloader.
They have two choices:
1 - Send it to LG to have it repaired.
2 - Wait for me to finish lafsploit 2.0 which will unlock their bootloader, and their phone will just start working.
The partitions that hold the unlock information are not touched when you flash a KDZ, so no amount of flashing is going to fix it.

If you cant get into download mode by powering off, holding vol up and then plugging into a pc (no power button needed) then you dont have a phone anymore. Unless rooted via dirtysanta which replaces aboot (which provides fastboot), the stock fastboot mode of the h918 can't actually flash anything to the phone which means no unbricking with it; TWRP and download mode are only ways to restore firmware.
I know this is an old thread but my gf has the h918 which is unlocked with twrp Installed, she tried updating magisk from inside magisk and now she's stuck in fastboot mode .The fastboot reboot command does not reboot the phone I even booted into twrp and wiped cache any ideas?

Can you use fastboot (volume down+power)? If you don't have Android SDK, then install Minimal ADB and Fastboot, open cmd in that directory and type "fastboot device" (or "fastboot devices"?) while phone is connected via USB in fastboot mode. If it displays your phone's serial number, then you can use fastboot. If it doesn't show you anything, then I think wiping your phone in recovery or performing a clean flash through Mi Flash is the only way. However, if you can use fastboot, then the next step would be booting into TWRP... but we'll get to that once you confirm if it's working or not.

Hi,
i have checked by typing command---fastboot reboot and my phone reboots and hangs at android one screen so that means i can use fastboot but strangely didnt see in fastboot devices but i found output for fastboot oem device-info where device unlocked shows false and other status.
If this is enough for using fastboot to boot into TWRP?

Actually bad news is that to boot into TWRP you need to unlock your bootloader first (fastboot oem unlock), but to do that I think you need to have enabled "OEM unlocking" in developer settings (though strangely I am unlocked, but for me this option is disabled). Try unlocking anyway. If it doesn't work, then I would follow this guide to clean flash official firmware with Mi Flash Tool. Be warned, you will lose all your data if you manage to unlock your device.

Hi,
Is that mean i will still loose all data even if i unlock bootloader?
And i am unable to unlock bootloader by command. So only option i have now to do factoryreset/wipe data?
So after factory reset again i need to flash the ROM ? Because if again i need to flash ROM, i understand the prerequisite is Bootloader unlock which will create issue again.
Please suggest.

No, if you wipe your phone through recovery you won't need to flash anything. It just deletes all your stuff without touching the system.

I'm in the same boat. Unable to access developer options as phone won't boot and its stuck at the android one logo.
Fastboot oem unlock gives error Flashing Unlock is not allowed.
Is there anyway around this?
I'm still stuck with my Mi A2. I didn't enable OEM unlock or USB debugging and now i'm stuck on android one logo with only option is to boot into fast-boot mode. All commands and tools i try I get error stating unlock is not allowed in Lock State.
I bit the bullet and ordered an EDL cable so we'll see if i get anywhere with that. I've read that newer Xiaomi devices wont work with EDL cable and only option is to use the test point method....not sure how accurate that is but guess i'll find out whenever the cable gets here.

You can try fastboot oem edl
To put the phone in EDL mode without specific cable
However why not wipe data from the recovery?
Just use fastboot reboot recovery

Hi I bricked my 6T. I tried to flash HavocOS ROM. But it wasn't installed properly where the systemUI wasn't working properly and I should've wiped my phone beforehand. I rebooted back into recovery and the internal storage was corrupted. I wipe data, but that didn't work and I wiped the system to get into a mode where the MSMDownload Tool can access it. But instead I'm stuck in Fastboot mode, but I could boot into TWRP.
But I followed this thread to recover my 6T through Fastboot, most of the commands worked not the system 'fastboot flash system_a system.img' this was the same for '_b' as well. It kept on saying 'error: cannot load 'system.img'' and now I can't boot into TWRP. Every option in fastboot mode just reboots to fastboot. I tried to get my situation across in each thread (Havocos and Fastboot rom thread) But no reply, I am running out of options and losing hope

You found the fastboot ROM thread, did you try flashing everything again from fast boot? Don't just flash what you think you need, reflash all of them. I got stuck in this loop recently and after flashing everything my phone booted as normal, and then I just started over, installing TWRP and rooting etc. Reloading AOSP.
Kept me from having to use the MSM Tool.

Is very simple to fix this....
Unplug... Hold power plus volume up till the device shuts off
Now with the device turned off and unplugged still.....
Hold both volume buttons for about five seconds and while continuing to hold plug in the USB..... Screen will stay black that's normal cause because the device is now in edl and the msmtool should be detecting it.......
