I've already tried using it without success because it didn't detect my device, but luckily i managed to repair my phone by changing the slots with fastboot command line tools where i still had oxygenos running.
Thanks though, how do i mark the thread as solved?

The MSM tool requires special drivers and your phone to be in a special boot mode, something like holding volume up while plugging it in or something.
Glad you got it fixed without the MSM tool though!
As for marking the thread solved I can't help with that unfortunately, sorry .

Greetings, I tried flashing my LG H440F to its original state via LG Flash Tool.
At the time being it was stuck on 1% and after several errors I desisted and tried another KDZ to flash with same result (stuck at 1%)
Now the phone is stuck in fastboot, I can't boot it to Download mode neither do a Hard Reset as it does nothing.
Adb does not recognize the device and fastboot always throws a FAILED (remote: unknown command) when trying to do anything.
Did I just entirely brick my phone?
Best regards.
No one?

Try to post it in general thread. Maybe someone there will look into it. Btw, fastboot is disabled on lg spirit, so any fastboot command won't work on it.

I have now spent the entire day trying to get this thing to work, and having used up all the help from xda, I am asking you guys for help. Here's my situation:
I am trying to install TWRP on my Zenfone Max Pro M1. So I followed all the guides available, and downloaded the drivers, unlock.bat, TWRP img etc and did what I have always done on all my phones.
My computer also recognizes the device when I try fastboot devices. But the second I try to fastboot flash recovery twrp.img, the phone goes onto a black screen with "Press any key to shut down" written on it. I have tried every combination out there, and I don't know what to do now.
Please help.
Did you unlock boot loader? After that press volume up and power button,then you can enter fastboot screen. After that use fastboot flash recovery twrp.img
I have same problem plz help
1. boot into fastboot.
2. make sure fastboot can see the device 'fastboot devices'
3. fastboot flash recovery twrp-xxx.img
4. boot into twrp.
Did that work?

No, you must have done something else too. I'm trying to use fastboot mode to flash the fastboot firmware using Asus Flash Tool but as soon as AFT detects the device, it goes all black with the screen saying" press any key to shut down". Did you installed any other drivers or used any other system to do it?

Nope. Just used Powershell to execute the bat file and then push TWRP.
CMD wasn't working for me.
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
If fastboot commands work, type in " fastboot reboot EDL "
then run the msm tool

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.......

Hello everyone. Today, I was updating the edxposed magisk module, then rebooted the device and now I cannot use it because it asks for a password. I am on Lineage OS 17, using latest Predator Kernel with latest magisk. I have Orange Fox recovery installed, but the thing is that I cannot boot into recovery mode to format data. I powered off the device, pushed volume up and power button but it was booting in the os, again asking for a password. I tried booting an image of twrp from fastboot and it didn't work, the phone either booted into the os asking for password or just powered off. Now I am trying to flash stock miui latest global with miflash tool and when i click the refresh button a box appears saying "Invalid class". I have all the necessary drivers installed. This error does not make sense to me since I have flashed stock firmware in the past on lavender using miflash tool. I searched on the internet and found no solution and very little information about this error. I cannot believe it, all of that because of a freaking magisk module update, I regret so much the moment I tried to update that edxposed module!
Anyway, I really am desperate at this point, I don't have much experience and I have no idea what to do. If anybody knows of a way to fix these problems, please reply as soon as you can, as this is my main device! Any help will be greatly appreciated.
If you have a backup of the boot partition, you can simply install the image via fastboot using "fastboot flash boot boot.img" and that should fix it.

Hello, thanks for the reply. I tried flashing my boot image but it didn't work, it was still asking for password. I also tried "fastboot boot boot.img" and same result. What I want to do at this point is to make MiFlash tool work so that I can flash the stock rom. For some odd reason on my computer it showed that "Invalid class" error. But now I tried using MiFlash tool on my dad's old laptop, and everything seems to be working here, no errors. At the moment of writing this the stock rom is being flashed. Let's hope I will be able to boot into it.
Good luck

Hello, I never found a solution to this weird error, but I didn't need to because I now use a different computer. I don't really know how to help you. I remember that back then it used to work fine but suddenly one day this error showed up out of nowhere. I don't know what caused it and there isn't much information about it on the internet. Maybe try putting the mi flash tool folder to different directories on your computer and see if that helps, try deleting it and redownloading it or check the log on the mi flash tool log folder. I remember that it didn't help me back then but maybe it helps you.
Elaborate a bit on the issue. What is your device? What did you do before the error started showing up? Try being a bit more specific and maybe someone else will help you.
If you have access to another computer, use that one as a temporary solution to flash your device.
Hi, thanks for the reply
I tried everything: Update windows, reinstall Net Framework, Reinstall MiFlash, use older or newer versions, Reinstall Drivers, use in different locations
I'm 99% sure the problem is not MiFlash but any component in Windows 10
Because I had other problems with other application with similar error
I have no idea, I don't want to format my computer...
My device is Dell E7240

Hello, sorry for the late reply. Unfortunately, I don't know how to help you. If you find a solution, please post it so that people who might have the same issue in the future know how to solve it.
Please, I also found this kind of problem on my desktop, invalid class when refreshing in the miflash tool. I am very sad
I have been on a journey trying to go back to my T-Mobile OnePlus 6T back as my daily driver but the official updates killed the device for me. I have been successful in flashing it to the international version and now the device is on A9. I am trying to get it updated to A10 but in order do that (does not take OTA updates or can not flash within the updates app) I have to flash in recovery. Right now it is on stock recovery so I am trying to flash TWRP.
The problem is now that everytime I run the command " fastboot boot IMAGENAME.img" the phone restarts (as expected) and boots into fastboot but stays stuck in the Fastboot Mode screen.
I tried different TWRP images (older and the most current version per https://dl.twrp.me/fajita/ ) but I keep getting stuck in the Fastboot Mode screen. The last thing I was able to do without issues was unlock bootloader using fastboot.
I just need to be able to flash TWRP on the phone so I can still the final stock image so I can go back to using it as my DD.
EDIT: Disregard everything I fixed it. mods, please delete thread.
EDITR 2: Disregard that last edit lol Yeah I still need help. I am now tryingto flash twrp on a second 6T and the issue described above still applies.
You can try this version. Also try unplugging the USB after it reboots. You aren't getting any crash dump screen? So it should be working.

Tried your image and still same result. I am running following command
Code:
fastboot boot TWRP-3.6.1_11-OP6xT.img
The command window outputs the following
Code:
Sending 'boot.img' (34964 KB) OKAY [ 0.747s]
Booting OKAY [ 0.092s]
Finished. Total time: 0.860s
The phone then reboots into Fastboot Mode logo and stays stuck there. I even tried unplugging the USB after it reboots as well.
I even tried using the flash command instead of boot but no success.
How about fastboot boot recovery? Should be able to get into recovery somehow. Doing fastboot flash of twrp will mess up your boot partition but either way you still should be able to get into recovery somehow. There is the msm recovery tool you can use as last resort but it will relock your bootloader
Actually fastboot doesn't let you use boot recovery command I don't think. Only adb. But once you are in fastboot can't you choose to reboot recovery with volume keys?

When I am in fastboot mode, yes I can choose recovery but it takes me to the stock recovery. I do not have a option to flash any zip files there
Maybe you need a twrp for Android 9 since that's what you are on. But fastboot boot twrp should just take you there. Either have to find one that works or go msm route. Maybe windows not reading it correctly also. You using CMD or PowerShell?

I tried both CMD and PowerShell. I am going to try a A9 version of twrp
EDIT: I am using twrp-3.6.1_9-0-fajita.img (which I assume is for A9) and still get the same result. Even tried a different usb port.. not sure what i could be missing. I also did the instructions as advised straight from twrp's website.

I don't know bud. I guess msm tool is the way to go then
Curious did you have the twrp file in same folder as adb and fastboot?
