MSM tool can get you back to stock. I've had to use it several times. It can be flashed from Qualcomm crashdump mode. It will wipe your phone and relock your bootloader (not optional) but you can unlock it again (another wipe).

i try write system again with msm flash tool but stock on oneplus logo ? what can i do ?
Sounds like it could be a motherboard issue
Are you wiping the system and data after using the MSM??!! Don't wipe after using MSM
MSM wipes everything for you. There's zero reason to be wiping anything.

guys i do msm flash tool and stock on oneplus logo looooooong time and i just wipe system sometimes to and its stock on bootloader and try msm again still on logo
Do not wipe system after msm, if you wipe it, there will be no system to boot on, wait after msm firstblot may take a long time
This made me laugh.

Did you fix the issue ?
Oneplus repair center in us are the fakest people I've ever felt with. Of coarse gutting out the motherboard will fix any previous issues but I've experienced my phone bootlooping then be perfectly fine after I flash firmware in fastboot. Now that peoples op6 are out of warranty won't even bother to do repairs on international phones they just want 6o sell you a new phone.

If I wipe the system after MSM flashing, will the reflashing with MSM fix the issue of not booting to OS? My 7T isn't booting to OS after this just shows a black screen.
Also the MSM tool shows 'Download Complete' in green colored text, I waited for half an hour too after seeing this, though when I'm trying to close the MSM Download Tool window it saying something like 'Downloading not completed'.
Also a few times the MSM flashing was doing the download process again and again endlessly and the phone was also (maybe) booting to this EDL mode repeatedly. I could also hear the hardware remove/plugging-in sound too from the PC.
Do you know what could be the issue with my phone?

Accidentally flashed a fastboot rom to recovey and boot.

A few days ago I bought a new oneplus 8t 5g from Tmobile. great phone. I unlocked the bootloader just fine. Going back into android, I noticed that there were no sounds at all, it wouldn't connect to wifi and was really slow. I had not rooted at this point. I tried a factory reset and this did not help. I tried to relock the bootloader when the phone said it was corrupt and would not boot. Edl mode was available so I flashed lineageOS. it never booted up after 2 days. Then I flashed a fastboot ROM. Now the phone will only boot to the bootloader, and flashing does nothing. I would like to restore the phone to its complete original state. The model is KB2007. Any help at all would be appreciated.
Maybe you should try Msm Tool .

You get 'remote: flashing is not allowed', because you have 'Oem unlock allowed' toggle unchecked in Settings/Developer, and since you can't boot your device to allow unlock, your only option is flashing with MSM tool.
But msm also I have tried, it's getting completed but device hangs again in black screen in logo mode, I have tried 3 different msm tools too

You can only successfully restore your phone with an EDL mode (where you turn your phone off, press and hold volume up and connect it to a computer with already started MSM tool). If the process completes, the phone should start. As a matter of fact, it should restart while the MSM tool is still working. Perhaps, it doesn't complete fully, because of a missing WIndows driver.
What did you do that has caused the problem?

It was sudden by itself, it was on stock os and setting never even tried root or unlocking anything extra, I think hardware is gone bad may be storage as me and 2 more technician have used all methods but failed, now they also said hardware change required some 3500 bucks cost, I have now purchased Realme GT 5g ... Now using this from yesterday it's amazing

Bricked OP7 Pro

Hello everyone.
I need some help i think. I bought a used OP7 Pro to try my hands at installing crDroid and changing this over to my work phone without any Google installed. I have successfully flashed ROM's on about 6-7 different phones successfully before - but not this time it seems.
I think I have introduced corrupted boot partitions (both a and b) and the phone is now barely alive.
I have it plugged in on the charger, but when trying to turn it on (using volume up and power) it says that power is low and that I should leave it plugged inn a while before booting up. Doing so leaves the phone to boot, but after the initial "warning" screen about the unlocked bootloader the phone dies and I have to try to turn it on again.
To make matters worse - i do not have a Windows machine to use to try to fix it. My personal one is Linux based (I used this for the failed flash attampt). I planned on following this guide:
How to Unbrick or Restore Back to Stock ROM on all OnePlus using this Tool
From this comprehensive post, you could unbrick your OnePlus device and restore it to the Stock ROM. We will be using the MSM Download Tool for the said
www.getdroidtips.com
This required a Windows machine in Test mode.
Any other tips or guide for me to follow that you recommened?
Thank you very much!

You don't have bootloader unlocked? You might need to find your correct msm tool for your device, depending on if you got your phone from OnePlus or T-Mobile, or send it in for repair? A few people on here, including me, also was able to send it to OnePlus via 1 day airmail and have it shipped back the same way and repaired all for free. That might not be an option for you though, I don't know how much you need your phone but if it's bricked either way it might be the best option. Try the msm tool first though instead of using fastboot to flash stock.

A phone wouldnt have an unlocked bootloader from the start right? I've never been this deep in **** with my android so this is all really out of my depth. Ill send a message to the oneplus support while the file from the other post downloads, maybe it'll work after all

My bad, didn't see that he changed op. I mean if he could not connect through msm, there are a few options to try, including installing a driver manually for the qcom device. I had to fiddle with drivers and whatnot for about an hour or so before flashing was able to successfully commence. msm should help but scheduling a remote repair might take a day or so from oneplus so might as well try you know?

No it would not, however msm tool does not use unlocked bootloader. I was informed that you tried it and it did not work and removed it from your op, but what would not work? was the device not seen on com port?

i havent used an msm? i couldnt get the com port to show up, or It was like showing up for short periods while i was doing certain inputs, but not long enough to get anything done

So you tried it though it sounds like. It requires specific steps to work. You need drivers to be installed, go into EDL mode by having the device off and holding volume up while plugging the device into your computer, and then you have to start it when the device is enumerated. Are you willing to try msm again? The only other options really are to have a remote session with oneplus, which might take a day or so to get done, or send it for free for repair?

its the holding buttons part thats a little weird but im definitely ready to try it again. The problem occurs with how my phone is powercycling by itself whatever I do while its not in fast boot mode. This makes the MSM stop detecting the phone and I have to start over.

Yeah, I have bricked my op9 so many times I know what you are talking about. With the power cycling thing I have no idea why that happens, but sometimes if I start the msm tool while it is detected, it will stay in EDL mode and stop cycling. Other times I realized that it was not really in EDL mode to begin with. Make sure that the device is completely off. Open up msmtool and get it ready. Hold volume down and up, without holding the power button, and then connect it to your pc. Once it shows up just click start. You might need to try different usb ports, and/or make sure that your drivers are installed for qcom device in edl mode.

Thank you! i think im ready to start this hell, the "qualcom something 8001ish" driver showing up(while the phone shows up in msmtool) would mean the drivers are correctly installed right?

I believe so? in device manager you should see the device and then COM... like COM4 or COM3 or something, as long as it is COM and then a number, and if it shows up in msmtool then the drivers are probably installed. The process won't work if you dont have drivers set right, so try it and if it fails make sure that it is the right msmtool and that you have drivers installed. Do not touch it while it is doing its thing, lay it down on a surface or something just to be safe. Also you might not have to do this but I have found success with msmtool by going offline like disconnecting ethernet and turning off wifi, and setting my date back to december of 2018 in windows before starting the tool, I do not know why but if it fails try that first above all else.

how do i make sure the phone is turned off, just when it goes black? and when I hold the volume buttons it goes into fast boot, does this mean I was too slow?

Yeah it should just be black screen. It goes into fastboot? You sure you aren't hitting the power button as well? In fastboot select power off. When it's off, hold only the volume buttons, and then plug it in.
