Hi good people at XDA. This is my first post on this website and I am absolutely hoping to receive help from you all to find a way out of the depressing and extremely anxious situation I'm in.

I was using my OP6 normally today and while I was typing something on Telegram the phone suddenly froze and after I re-booted it, it took me to the Qualcomm Crashdump screen.

My OP6 isn't tampered in any way (no bootloader unlocked, no TWRP recovery installed, nothing rooted).

At the moment, I can enter the fastboot mode while pressing volume up and power button.

The crucial thing is the data which I MUST RETRIEVE, can't afford to lose it.😭

Could y'all please suggest a way where the data can be retrieved or the phone can be revived without data loss?

I did read the forums on MSMDownload Tool but I believe it wipes off the phone, right?

PLEASE HELP!

If ADB ( read: USB Debugging ) got enabled on phone - what is the door to Android OS - then try this to pull out user-data stored on phone

Code:
adb devices
mkdir "C:\RECOVERED_DATA"
adb pull /sdcard   C:\RECOVERED_DATA

Thanks @jwoegerbauer for the prompt response. I can surely try that. Considering that I'm fairly a noob, could you please share in a bit detail, the steps I need to take before executing those commands?

Also, since there's a tiny chance that USB Debugging may not have been enabled, what's the alternative that I consider?

Thanks!

Since I must retrieve the data in internal SD, can this help me enter the OS?:

1. Extracting the boot.img of the latest version that's currency installed on my OP6, from payload.bin
2. Testing if this boot.img can revive me into the OS by fastboot boot boot.img.

Also, one pressing doubt: does a fastboot flash boot boot.img command erase internal SD contents??

Please help!

My friend has the same problems. Did you find any ways to retrive data? I found a way to use msm tool but it surely erases all data and its his college memories so I'm trying to find alternate ways. Does the msm tool work on bootloader locked phones?Sorry that I am of no help to you. I too am a novice
No man. Still looking for some solutions. Read umpteen threads only to see that MSMDownload Tool erases data because it first unlocks bootloader (which mandatorily wipes data), flashes system files and then relocks it.

But I'm pretty sure, there exists some way out to flash a OP 6 with locked bootloader but retaining userdata partition intact.

Hoping to receive some solution here from this community of Android geeks.

Hey man, were you able to do anything abut it? I'm in the exact same situation. Don't mind losing the phone if I'm able to save the data.

Hi. So, I gave my phone to a phone repair specialist. Apparently he changed some IC, which made the phone to boot up to the system. which is what allowed me to take the data backup of the phone.

Oh, that's awesome. I have some hope then. Do you mind telling me what your location is. I'm based out of bangalore and wondering I'll have to take it to your specialist incase I don't find any solution locally. All others have been saying they were asked to replace motherboard by Oneplus service centres. Please let me know of your repair centre as well. I'll try to atleast speak to them. Thank you so much

like many even i too ugraged my op6 to oo11.1.1.1, rooted was running well for a week till i encountred face crash dump mode error

Stupid thing i did was instead of flashing fastboot oos 10.3.8 i tried to flash msm 10.3.8 which didnt solve crash dum and also locked my BL.
now nonof the msm could solve crash dump nor we can unlock BL bz we cant toggle OEM in Dev option,

i discussed with @L0ND0NB0Y regarding this, his suggestion would be to take a backup of oos10.3.8 config partation of a working rom, then use edl to flash it on affected op6, by that way we can unlock bootloader and flash fastboot rom.
we need to fide a working op6 and back config which @L0ND0NB0Y can guide us. if it works he ll creat a post to solve crashbump and BL locked issue.

if this wont work, we may need to wait for msm oos11 file.

update : managed to solve crash dump by flashing msm international 5.1.5 but ended up getting black screen with white notification light, if my op6 had BL unlocked all i had to do is to boot stock/twrp recovery and factory wipe.
