OnePlus 7T bricked on Qualcomm Crashdump mode, unable to boot to fastboot - OnePlus 7T Questions & Answers

Hey everyone!
So, I've got a HD1903, 8GB RAM 128GB ROM. I updated to OxygenOS 11.0.02, but it was still buggy as hell, so I decided to downgrade. I also had rooted the phone, and decided to get rid of that too. I went to the stock fastboot roms page, downloaded the 10.0.13 ROM and used 'flash-all.bat' file to clear everything. But halfway, it reboots, goes into recovery, then goes to Qualcomm Crashdump mode. That's it. No code or anything, just Qualcomm Crashdump mode, in Blue and Red letters. I tried to hold vol-up, vol-down and power to get into fastboot, but it just loads the fastboot splash screen, then goes back to the same qualcomm crashdump mode screen. Even if i try to hard reset it, by holding vol-up and power, it still goes to the same screen.
Anyone know what to do? I have no idea how to use the 'MSM tool' that everyone talks about, so any guiding advice would be great!
Thanks!

DM me here - https://www.facebook.com/prantor.khan.16 I'll help

I didn't install TWRP, this was all on stock recovery. I also cannot get into fastboot mode.

Msmtool does not need twrp or fastboot--just the software, rom image, drivers, and button combo pushes and holding

OK, so I got it working again, thanks to the advice of reddit users, discord users and the latest msm tool and some googling. I held the vol-up and vol-down buttons for 30 seconds, then connected it to the laptop, with msm running, to a usb 2.0 port, and pressed start. hey presto, it worked. Thanks guys!!

Hello
Using the MSM tool is very simple, you just have to download it from this link.
https://drive.google.com/file/d/12y3lO0wIgb2_LSDeVw9x_2C_HjbgZlb_/view?usp=sharing
NOTE: only works on Windows PC
1. Unzip the contents of the RAR into a folder.
2. Run the MSM application
3. Click Start.
4. Connect the cell phone in EDL mode (volume up + down button)
5. Wait for the process to finish (it takes a long time, please be patient)
6. The phone will restart automatically and a message will appear informing you that the equipment is damaged (don't be careful).
Note: The phone should automatically boot into fastboot mode and display a menu, but if it doesn't and instead boots to the T-mobile screen, you need to force shutdown with the power button for several seconds and then manually start it in fastboot mode. (volume up + volume down + power button)
7. Now you need to unlock the bootloader with the command from a Windows CMD window, but you need to download this ADB tool first.
https://dl.google.com/android/repository/platform-tools-latest-windows.zip
-Unzip the tool into a folder
-Open a Windows command window, in administrator mode and direct it to the path where you unzipped the ADB tool.
8- Execute this command while the cell phone is connected in Fastboot mode.

9- A question will appear on the phone in which you must allow the unlocking.
-With the volume keys select the option to allow it and press the power button.
-At this time your bootloader will be unlocked.
10. Copy the ADB tool files into the folder where ROM 10.0.13 is and replace everything.
11. With the phone connected to the PC, on the command line, run the flash-all.bat file
12. When the phone restarts and the yellow and white letters appear informing that the phone is not safe because the bootloader is unlocked, repeatedly press the (volume down) button until a menu in Chinese appears.
-PC will detect the phone again in fastboot mode and continue to flash
-Leave the phone and PC still until the process is finished.
-In the command line it will indicate that it cannot find files or partitions (ignore it)
13. Finally, the computer will restart automatically and you will be able to use it normally.
Notes:
1. If the phone after the flashing process with MSM starts up and shows the T-mobile logo, don't worry, just turn it off with the power button and connect it in fastboot mode.
2. Do not try to use it with the firmware that I install with MSM, as it will not work properly.
3. Before locking the bootloader again (if you plan to do so) first update via OTA, to the most recent version of Oxygen, otherwise the system will crash again and you will have to repeat the whole process.

Oh wow that was a long and well defined post. Thank you for taking the time to type it out.
As it happens, I fixed my issue already (IDK if there's a solved flair for XDA or something?). I downloaded the latest (10.0.15) MSM Tool from the XDA page, held the vol-up and vol-down for 30 seconds this time (as per advice from discord users) got the phone into edl mode, connected to a usb 2.0 port and let msm tool do it's thing. Everything is working perfectly now.

I've got the same problem but even with holding vol up+down buttons for 30 seconds I can't get into edl mode. It boots into qualcomm crashdump mode. I don't have fastboot working, I only see fastboot splash screen for a sec and then qualcomm crashdump mode appears. Could someone help?! As soon as usb cable is connected phone boots into qualcomm crashdump mode. no matter what I do.

Also do service centers undertake servicing for such phones which bricked because of badly flashed roms.

If they're going to just change the motherboard, I wonder what the EDL mode is meant for. Anyways, I won't go for motherboard change one can buy a new and better phone at that kinda price.
Anyways, I Fixed it through EDL method, you have to hold vol up and down simultaneously and immediately connect to windows (while still holding both buttons) via original USB cable. Check with Device manager if your device shows up, it's easy enough but you might have to keep trying to you get it right. Thereafter, disable driver verification in windows and if Sahara communications failed message appears in msm tool, turn off phone and repeat the procedure again.

The repair peeps only fix hardware and not software. It's more cost effective for them to swap out hardware faster than messing with msmtool like us

OK, so you won't get any confirmation that you're in EDL modem you just have to wing it. What I did, I first opened the MSM tool on my laptop, connected the USB side to the laptop at a USB 2.0 port, and kept the USB-C side within easy reach. I held the buttons down with one thumb for 30-35 seconds, and while still holding them down with one hand, i connected the cable to the phone and clicked enum in MSM, it showed connected so I let the buttons go, and it didn't restart. I clicked start, and it worked for me.

You don't have to hold buttons for that long, you can immediately connect it to PC. There is usually a sound to indicate that a new device has been connected to windows, you can also keep device manager open for confirmation. This video really helped.

After receiving a " qualcomm crash dump" , I was able to boot into recovery. Then I had done a factory reset.
Phone turns on fine, charges as well.
Although, On my Laptop / Desktop it does not see the phone within MSM, ASs well as ADB, Fastbootd or device manager.
I have the correct drivers downloaded.
Ideas ?

Tried both, my desktop would always connect, adb, fastboot, etc.
I had just just freshly installed oneplus drivers including qualcomm on my laptop. Device was not recognized before driver installation or after.
Figure id try on my Mac, and linux laptop. no dice.
ADB is enabled.
Here are the drivers that are installed on my PC ( I enabled hidden devices, in order to see them ) These were recognizing prior to " qualcomm crash dump" . Not phone will not even be seen

Boot loop issue: cannot get into fastboot from "no command" screen

Hey everyone,
A2 lite phone is in bootloop - allegedly (not my phone) "out of nowhere". The user does not do any fancy things like flashing, and this has not been done either.
Phone is on continuous boot loop, and sometimes (really seems randomly), the device starts up in the "no command" mode and stays there for a while. I read that we could go into fastboot mode by pressing "power button and tapping volume up key", but this doesn't do anything.
I've tried this thread: https://www.the***********.com/boot-xiaomi-mi-a2-fastboot-mode-recovery-mode/
But I'm not even getting into fastboot.
I'm almost thinking that the volume buttons are just broken, though from the feedback of the buttons this doesn't seem realistic.
EDIT: ok, now I'm somehow able to get it into fastboot.... sometimes. Now I'm here:
I switched the partition from a to b, but it still goes into bootloop. Then I switched it back to a, still bootloop. Then back to b. Still bootloop! But at least now sometimes I'm able to get into fastboot. No matter what kind of commands I'm typing in the cmd console, after about 10 seconds on the fastboot screen, the phone just reboots.
idk, it looks almost as if both partitions have the bad android 10...
Do you guys have any idea? Please let me know if more info is helpful.
You go into fastboot mode by holding Vol Down + Power button. So try holding Vol Down and Power button at the same time to go into fastboot mode. (Don't tap it)
Go here and grab the image you prefer (latest should do the trick) : https://forum.xda-developers.com/mi-a2-lite/how-to/fastboot-xiaomi-mi-a2-fastboot-images-t3824871
Then go ahead and follow this guide here to flash the stock ROM : https://c.mi.com/oc/miuidownload/detail?guide=2
This will wipe the data on the device, but it seems like you have no other option at this point. Cheers.
Thanks! I've tried that now. It starts flashing the device until... after about 10 seconds, the phone reboots from Fastboot mode .
As per this page: https://twrp.me/xiaomi/xiaomimia2lite.html
I've tried to do a recovery via TWRP. If I execute `fastboot boot path/to/twrp.img` then I go from fastboot to TWRP (the teamwin logo), but right after that the phone already reboots.
https://www.xda-developers.com/how-to-install-twrp/ - I don't know if it means anything, but when I execute `adb reboot bootloader`, the console returns `error: no devices/emulators found. If I execute `adb devices`, it does not list my device. However, if I execute `fastboot devices`, my device is listed.
I installed ADB usb drivers, so when I get my phone connected in fastboot, it shows up as Android Bootloader Interfacee in device manager. So not sure what's going on here, but it's all weird.
What I'm facing is very, very similar to https://www.reddit.com/r/Xiaomi/comments/4ltzt9/xiaomi_mi_note_boot_loop_even_in_fastboot/ <-- but that thread is a bit of a dead end (and 3 y/o)...

Hmm, it should never do that, maybe it's a hardware issue that we can not fix via Fastboot ?

When the device is in Fastboot mode, it will only be recognized as Fastboot. Only when it's properly booted, the device can be recognized in ADB, so no issues there.
I assume your bootloader is already unlocked as you have successfully booted into TWRP. You might try EDL (Emergency Download Mode) flash as a last resort :
Download MiFlash (20160401) from here : https://www.xiaomiflash.com/download/
You're downloading that particular version because it is able to EDL flash on your phone. Install the MiFlash you've downloaded and open it, then put the phone into fastboot mode. Connect it to your PC and use this code to take the phone into EDL mode:
Code:
fastboot oem edl
After you hit enter, you will see the screen turn off and notification LED blinking, this is normal. This means the phone is in EDL mode. Open the MiFlash you've installed (likely in C:\Program Files\Xiaomi\MiPhone) and browse to the ROM location and connect the phone. Choose "Flash All" and start flashing.
After the EDL flash is complete the phone will not reboot. It will stay in EDL mode. You need to disconnect the phone from PC and hold power button (about 10-15 seconds) to boot the phone. If the phone boots properly, you can go into fastboot and connect it to PC, then use:
Code:
fastboot oem lock
to relock your bootloader. Try it and let me know. :fingers-crossed:
Thanks for the continued help!
I've followed your steps - When I run fastboot oem edl, the console returns "... okay [ 0.0202s] finished. total time: 0.022s" and the phone turns to a black screen (no notification led blinking). Then... after a couple of seconds, goes back into the boot loop .
Something maybe to note: every time that my phone starts up, it (1) shows a screen saying "Your device software can'tbe checked for corruption.Please lock the bootloader.", and then slides down to the typical "androidone" white screen before it reboots again.

The screen with the ugly text is normal, since you have an unlocked bootloader, it's there to warn you that the device's software might've been tampered with. On the main subject though, I'm out of ideas. You might try booting the phone by holding Power + Vol Up, which should normally boot into stock recovery or wipe the data on the device. But I'm slowly beginning to think that this might be a hardware issue rather than a software issue that I can help you to fix.
Under normal circumstances, EDL flash is the way to fix any problems you might encounter with the software, that's why it's called the Emergency Download mode. But since we're past that stage, I believe I will not be able to assist you further. Hope you can fix your device my dude/dudette!
If the phone gets out of fastboot mode your phone does not get recognized from your computer. Try to delete fastboot and minimal adb and download the latest version. [https://forum.xda-developers.com/android/general/tool-adb-fastboot-installer-tool-windows-t3999445]
Open MiFlash, click Driver left on the top and install them.
Set path to the downloaded firmware. Now boot into fastboot, once that is done connect your USB cable to both, computer and phone. If this doesn't work try different USB-Ports and USB-cables. Some work, some don't. This might be the reason for leaving the fastboot mode.
Click refresh and see if your device appears

 @Cappucinto, thanks for chiming in! What do you mean with this: "Open MiFlash, click Driver left on the top and install them." <-- in MiFlash, I do not see an option to select driver...
What did change now after installing these drivers: https://forum.xda-developers.com/android/general/tool-adb-fastboot-installer-tool-windows-t3999445]
I did try some other USB cables. The one I've been trying triggers the windows sound for "new device successfully connected" when I boot the phone up in fastboot, and then of course gives the "device disconnected" sound when the phone then reboots. With another USB cable in this case, windows just states: "USB device not recognized". So it seems like the cable I haven't been using is defect .
I'm unable to use MiFlash at the moment so I can't explain the whole procedure with installing the drivers in MiFlash. But there has to be something like "Install > Drivers" or something. Maybe someone else can help out.
Try to use the working cable again, open a command prompt and type: fastboot devices
Then wait for an answer, post it here and see if the phone reboots again or if it stays in fastboot

Follow the instructions, as dat was how i revived mine. Hopefully it may help u.
Note; wen using twrp, preferably use " twrp - offain "
Miflash tool:
Link 1: https://www.xiaomiflash.com/download/
Preferably use Link 1 & choose either 2016, 2017 or 2018 versions. They come preloaded with the drivers u need
Link2: https://xiaomibuzz.com/downloads/download-xiaomi-mi-firmware-flash-tool-latest-version-2018.html

remember to use "twrp offain for daisy". It works better than the regular twrp for daisy
It my take and procedure that worked for me at the time. Good luck tho
Thanks! Sadly, when I get to the `fastboot oem edl` step, it fails. I get into fastboot, I quickly enter `fastboot oem edl`. CMD says finished, the screen turns off. I immediately refresh in MiFlash (COM3 is the device), I start flashing. After 4 seconds, the device turns off (windows sound "device disconnected"). The flashing runs for a total of 7-9s says "the operation completed successfully.(0x000000000: cmd <?xml version="1.0" ?><data .. etc etc
So I don't really know what to do if I can't get into EDL mode .

Try getting another chord and try again.
Tried some other cables. Every time I run fastboot oem edl, it keeps saying "finished", and then reboots the phone in about 5 seconds. One time, it said "Catastrophic failure" as "status" for the flashing.
Otherwise, it most often says "The operation completed successfully.(0x00000000: cmd <?xml version="1.0"?><data><patch SECTOR_SIZE_IN_BYTES="512" byte_offset="16" filename="DISK" physical_partition_number="0" size_in_bytes="4" start_sector="NUM_DISC_SECTORS-1." value="CRC32(NM_DISK_SECTORS-1.,92)" what="Update"/></data>)
But then still continues in the bootloop...

Question Oneplus 9 pro bricked, impossible to get to EDL

Hey all,
So i've unlocked by bootloader, flashed a custom recovery to then proceed with LineageOS flashing. However it went completely wrong as on reboot i'm stuck with the bootloader unlocked warning and then a blackscreen.
I still have access to fastboot mode however it's impossible to flash a customer recovery ("No Such Partition") and also impossible to directly "fastboot boot recovery.img" as the phone simply reboots on the warning and then blackscreen.
The only solution seems to get the device to qualcomm EDL mode and reflash all with the MSM tool (which I have as well as all the drivers) however I cannot get my Oneplus 9 pro to EDL mode...
I've tried all the fastboot commands (fastboot oem EDL, fastboot reboot EDL, none of them work) as well as the combination volume UP + volume DOWN + plugging the cable (it just boots the fastboot mode.
Honestly would greatly appreciate any help as it is the first time in a decade I hard bricked a phone like this as it seems all the partitions are broken.
Make sure you have it unplugged when you do the button combos, as it will just start to boot while it's plugged in. Also, if you can reach fastboot, you can almost definitely reach EDL. Try unplugging and holding power+vol up for a bit which forces it to completely power off. Then try getting into EDL through the normal button combo/plugging. This is what I had to do since once it got into the booting/no-booting cycle I couldn't get to EDL.
1] Make sure you have it connected directly to your computer via USB port rather than via a USB Hub, I've seen that cause the device not to show up in the device manager.
2] You might have to restart your computer with driver signing disabled, check here for instructions for that
3] I've uploaded the Qualcomm drivers here
4] Make sure you use POWER + VOL DOWN + VOL UP and watch your device manager to see if the device is there
5] Make sure you choose the correct MSM tool from here for your region/provider
6] Remember to use MsmDownloadTool V4.0.exe, choose "User type : Others" and choose the correct device/region under the top "Target" dropdown.
7] If you don't see any COM device showing connected then try changing USB port or rebooting the device back into EDL mode.
Good advice above.
Last time I couldn't reach EDL with my previous phone, it turned out to be an issue with the drivers I had installed. I uninstalled all Android-related drivers including some generic thing that showed up in device manager when plugging in the phone, then reinstalled the latest Qualcomm drivers.
Also possibly try a different USB cable if you have one. My OP9P didn't show up when the cable it came with was plugged into my USB-C port for some reason, but it worked fine with a generic Type-A to C cable I had sitting around.
Thanks a lot for the different guidelines !
i'm 100% sure the drivers are working. I have another oneplus 9 pro that is detected when booted on EDL mode on the PC. The faulty one however cannot reach it. Also it cannot get any charge as whenever I plug it on it just goes on a boot loop. Tried to leave it to charge for a full night but still shows the "out of battery logo" with the red cable.
When plugged to the PC while pressing VOLUME UP + VOLUME DOWN I keep getting the windows sound of device plugged/unpluged, etc etc...
To be honest I think the flashing messed up the partitions as it is now hard to do anything with this device...

Can you help me too, I have exactly the same problem…
If you use Windows, you need to see "QDLOADER 9008" in Device Manager > Portable Devices.
When you got this it will work, 100% .
It worked for me a few days ago. My laptop runs on Windows 11 x64. And only have usb 3.0. NO usb 2.0.
was having the hardest time as well, it's not that the device wasn't going to EDL mode, it was but it had the wrong driver installed, thus making MSM tool not detect it in time, it is a very small window that you have where the device goes into EDL mode and the MSM tool detects it, makes a handshake with it and starts the process, but if you have the wrong driver, MSM tool will not detect the device and the device will just turn back into fastboot mode, I'm attaching a picture of the device manager where the said driver is under "Ports" ( COM & LTP ) make sure you download the above mentioned drivers, if there is any other driver under Ports, uninstall it and whenever you plug in your phone with the VOL + VOL - combo, you will see the device appear under PORTS, upgrade the currently installed driver for the one called qcmdm.inf which you'll find after you extract the .cab file that you downloaded previously, after that open MSM Tool and hit start, the port number should match the one on the device manager, now unplug the cable from your phone, power it off and do the button combination and then plug in the cable, MSM should instantly recognize the device and start the restoration.

Yeah make sure it's exactly the same name of that driver - worked for me on oneplus 9
If you have access to fastboot still. Try switching slots. Then going into EDL
For anyone looking for help, please DM me.

1] Make sure you have it connected directly to your computer via USB port rather than via a USB Hub, I've seen that cause the device not to show up in the device manager.
2] You might have to restart your computer with driver signing disabled, check here for instructions for that
3] I've uploaded the Qualcomm drivers here
4] Make sure you use POWER + VOL DOWN + VOL UP and watch your device manager to see if the device is there
5] Make sure you choose the correct MSM tool from here for your region/provider
6] Remember to use MsmDownloadTool V4.0.exe, choose "User type : Others" and choose the correct device/region under the top "Target" dropdown.
7] If you don't see any COM device showing connected then try changing USB port or rebooting the device back into EDL mode.

Thanks a lot man. Saved my Day. First 9Pro successfully restored ;-) Thank you and merry Christmas to all.
Guys I do not need to use the MSM Tool Anywhere until I reach the step where my device is being successfully detected as "QDLOADER 9008" in my windows device manager correct?
Or does the MSM Application need to be running when I reboot to EDL mode?
I am following this guide.
Please help
I always have phone powered off, and while holding both volume keys I plug it into USB cord(that is already plugged to pc) and then click on enum(button in msm screen) until it says connected then hurry and click start. Once it starts I can let go of volume keys.. Also more than likely u will need to click the box to "use lite firehose" or "Sahara communicaion" will keep failing.
make sure you have oneplus 9 pro drivers and " qaulcomm incorporated - Ports" Driver) and ("qaulcomm communications inc-Net" Driver) so your phone in edl which will be already most likely be running before you plug it in. just hold down both volume buttons and plug in to the usb port to your pc and release once plugged in and start the msm tool and hit enum it should say connect provided that you have all the necessary drivers above so the pc usb port will be able to communicate/recognize you device. its never usually A 1 and done type of thing. everytime i brick my phone its always the 100th try before i get a com port connected and the software communicating successfully, so just be patient and take your time. you will get it back up and running,
Hey, I wanted to ask in here instead of starting a new thread.
Right now I have an OP9p that wont boot to EDL (Only fastboot or Corrupt page)
I tried the fastboot commands but it won't work and it won't shut down, I have fixed multiple phones using MSM and know all the small issues and how to get around them but it's the first time finding a device that won't shut down and will keep rebooting tried volume up + Power for several seconds tried holding only power or the three.
Nothing it keeps rebooting and won't shut down for me to get into EDL.
Any ideas?
Thanks

Well you have a corrupted boot.img or you would not be trying to edl. Also you probably are holding down multiple buttons to power off to your phone and your either not remembering or forgot that these combination of buttons are booting you into other modes fastboot, recovery or system.

Nord N100 EDL Mode - Dead / Gone

I flashed the 11.0.1 global boot image to my BE82CB to attempt root via these instructions: https://forum.xda-developers.com/t/...eplus-nord-with-magisk-and-temp-root.4340113/
Unfortunately, it bricked my device. It boots to a T-Mobile loading screen but feezes there.
I'd like to use the MSM for 10.5.8.BE82CB to unbrick this, but I can't enter EDL mode. These are the ways I've tried:
a) hold down vol up / down for 10 seconds - attach USB
a result) device boots to fastboot
b) fastboot reboot emergency
b result) device boots to fastboot
note: even just plugging in a charging USB boots the device to fastboot
Any ideas on how to get my phone into EDL mode, or did I kill it and permanently brick my phone?
let me help you here. if youre in fastboot you still have flashing access. do you remember your old version number?
I have exactly the same problem, after installing twrp I accidently formatted some partitions including system, and they aren't mounted, because of this I can't use edl and i can't decrypt data to get access to system partition. I can use only fastboot.
does fastboot reboot edl work? if not you might have to buy a deep flash cable off amazon to get it into edl, only about $10-15
You have to enter recovery mode and make windows look for the Qualcomm driver first. May take a few reboots of the phone in recover to trigger windows but you'll see optional link inwindows update when it does find something. Click and download the comm driver. mine was "Qualcomm HS-USB QDLoader 9008 (COM3)" your COM may not be COM3.
Reboot PC and turn off phone.
Open the msm downloader and click start
hold UP and DOWN only - plug in phone -> phone will seem like nothing happens but you should see a COM pop up in the software
then continue with the download, it take some mins.
hope it helps some. I have N100 sprint/t-mobile
i can say that the software saved me for sure. it took me back to android 10 but im ok with it.
Possibly unrelated, I was testing different GSI images accidentally wiped system. wouldn't turn off just rebooted. I was able to get into EDL mode I just had to hold down volume up & down just after selecting power off in fastboot menu. maybe this will help, but no guarantee.

I had to use a cable, but it worked well. Make sure the drivers are installed before. It took a few tries and I had to rotate the cable, but it worked eventually. Install the drivers, reboot, make sure phone is off, plug in cable and press the button. Qualcomm should show up under ports in device manager and you should be all set.

Question I am stuck in fastboot and can only boot into fastboot please help??

I can only accsess fastboot and cannot reboot into anything except fastboot.... I tried extracting the payload bin but can only flash a few lines then I am told to reboot into fastbootd but cannot access that either... I cannot access recoveries either and I have tried to flash them but still wont budge... any ideas??
Use MSM tool
I also have this problem and I can't get it to EDL mode nothing happens stuck in fastboot.
I just typed a whole guide on how I managed to solve this in detail and the tab got closed out... in short then, download Qualcomm drivers and not oneplus's. There are many drivers in the file, just extract the whole thing and point to the file on device manager and include subfolders. It should find which I think was the HS-USB QDloader 9008 driver then install. Make sure you download the correct MSM for your version. The latest for global (or O2) is only hosted on one server and was going to take 12 hours to download on highspeed internet so I used lemonadep_22_O.05_210324 being 11.2.2.2. Use the Win7 version. Even though you cannot use EDL, you can reference these key combinations to get it recognized. If you're having a completely black screen, use the all button press hold until it vibrates. Make sure you are shutdown all the way and if needed use fastboot to. With MSM opened, drivers installed, and phone off, hold both vol keys and connect to PC. Hit Enum to refresh connections and hopefully it shows up and you can get a successful download complete. I found that the black screen was actually the device being in recovery mode. It was possible to successfully enter recovery using boot with power and volume down at times, although all sideload OTA's (along with prior fastboot flash boot *.img, fastboot -w, fastboot update, fastboot reboot-edl, ect.) failed. There was a lot of trial and error where just repeating some things after they had failed almost magically started working or stopped however this process is what worked in my case.

Yeah but that was a hassle should've been easier to reach that interface. I was almost sending it to service for nothing but a stupid unreachable interface nonsense.
Also to note when I tried with original cable from the box was successful the other usb cable gave me problems.

Question Need help unbricking -> EDL not accessible for MSM

[SOLVED see post below]
Hi all,
Just bricked my Phone and can't access MSM. Hope you can help me. I will try to be very clear on the steps I took to get to this point.
Device: EU OnePlus 9 Pro
What is was trying to do: Go from rooted C.47 to Pixel Entended ROM
What I did:
Code:
Unrooted using Magisk uninstall option
Updated to c.48 through OTA
Go to lineageOS page on how to ensure all firmware partitions are consistent
very stupidly did not flash dtbo and vendor boot partition
did adb reboot fastboot in stead of abd reboot bootloader
Download the "lineage-19.1-20220701-recovery-lemonadep.img" and tried to temporaryly flash it by
fastboot flash boot <recovery_filename>.img
This resulted in the device getting stuck on the 1+ boot logo.
I can still force turn it off by holding Volume Up + Power.
When I try to access EDL by turned off and Vol UP + Vol Down + Plug and release, My PC makes a connection sound and the screen stay black for a while. After +- 10 seconds, the PC makes a disconnection sound and the phone boots up and gets stuck again on the 1+ bootup icon.
Also my phone won't stay turned off when plugged in the charger or pc
Yes, but what is it presenting as (i.e. EDL, fastboot, ADB, UMS...) when it connects?
If this is Windows, UsbLog.exe is handy to identify things popping up (as long as they have drivers installed).
For a list of devices that have ever tried to connect, try "enumusb.exe /l".
Both available here: https://www.temblast.com/windows.htm

I will try this
I found the issue:
> EDL exits after 10 seconds if it is not captured by the MSM tool.
> The MSM tool only monitored 4 of my 10 USB ports
> So it was not captured because I was plugged in to an unmonitored USB port and rebooted after 10 seconds
> I have successfully used the MSM tool now
Oh! A bit off-topic, but I have never understood why EDL is commonly used over a "serial" port.
The interface that EDL presents is a generic USB bulk interface with two endpoints. You can use it just like that.
But no. They have to use a Qualcomm driver that makes it look like a "serial" port and then you can connect to that.
Me? I use a generic "WinUSB" Zadig driver. I have an EDL client that just connects to that fine.
So does the Python client implementation.
Also, I've never run into that 10 second timeout.

Your phone needs to be in OFF state mode when you're using EDL.
So, very simple:
Enter bootloader mode by holding both volume buttons with the power button together till your phone restarts and enters the bootloader.
From the bootloader screen you can use the volume buttons to navigate through the choices and you can select "Switch off".
When you complete this, you need to hold both volume buttons, and while holding them connect the cable (PC).
If you don't have or you don't have the correct Qualcomm EDL drivers installed, your phone will reboot or start to boot, it won't stay in EDL mode for longer than 10 seconds.
I also got the correct drivers for you, but you need to install the drivers manually while your device is in "EDL" mode, so, you need to be a bit "fast".
I have even a video for you, but need to upload it to YouTube so you can watch it.
I'll share you here the drivers just in case if you're familiar with a manual installation of the drivers.
