OnePlus 6 crash dump - multiple users facing crashdump mode issue in past two months

[yawarkhalid]

So I've been using my OnePlus for about 2 years. The phone was kept in a rugged armor case, never dropped nor was it ever exposed to any sort of moisture. The device was never rooted nor was the bootloader ever unlocked.

At the end of August 2020 last month I was using maps when it suddenly crashed and went into Qualcomm Crashdump mode. I thought not a big deal, xda would have a fix to this.

I came home and for two weeks I tried different builds of the msmdownload tool with different methods to revive the phone. None of them worked. The 9.0 build did end up booting the phone but only for a short while before it got stuck, shut off and went into crash dump mode again. I can only boot into fastboot mode and that only sometimes (ofc EDL mode as well).

Fed up, I contacted OnePlus and scheduled a remote session with them. As was no surprise they used the msmdownload tool as well (build 10.3.0). And it obviously did not work and adviced me to visit the nearest support center. Unfortunately there is no service center nearby in my country so I dug deeper trying to find people with similar issue. Now this is the funny part.

On the brands own community app I found 5-6 other people who faced the exact same issue. They tried everything and when nothing worked they eventually went to the service center and were told that apparently the motherboard needs to be changed and it will cost as much as the phones value in today's date. Here's the interesting fact. All these 6 users were on the latest OOS 10.3.5 and faced this issue in the span of those 4 weeks. August to September of 2020.

The purpose of this thread:

1) To diagnose the issue with the help of the xda community as I believe that there is no way that the mobo could get fried this way.

2) To possibly find a solution as the phone is in absolute scratch less condition.

3) and most important, to find other people than those 6 who have faced this exact issue in the past couple of months so that it could be raised with OnePlus. Im hoping that OnePlus could at least diagnose it and release a tool for the fix if there are enough of us. Wishful thinking maybe but worth a shot.

Hoping for your support. Peace.

Guess what might be 7th person. My oneplus 6 keeps shutting down all of a sudden and some times even wont start or something might start but again goes off while booting. So, then i have to start it after 10 mins and so and start it again and that too wait for 5 to 10 mins after starting before start using it or else it goes off again. Cant use it for heavy usage any more like before. Sometimes even turns off all of sudden. i have used all msm tools to reinstall but no use. Funny thing is while evening setting up the phone after flashing it goes off. Dont no if its hardware problem or not. I also have not dropped my phone.. Can any one find whats the problem?

@ms2020 has the same exact problem as you describe here but on 6t. We did all we could. I even tagged osmosis and he said if msm tool won't work then unfortunately it's a no go...

Same problem here. I have two OnePlus 6. One has OOS 10.3.5 with a locked bootloader, the other one has a custom rom.
6 weeks ago I was using google chrome on the one with OOS and suddenly the phone froze for few seconds and went to crash dump mode. I tried every msm tools version and every suggestions I found, but none of them worked.
The one with custom rom hasn't had any problem so far.

@saban56

When did you lot face this issue? I'll be raising the issue with OnePlus. Hopefully they could diagnose this and release some tool to fix this if there are enough people out there.

I think it was around August 19th or 20th.

This leads me to believe perhaps the same will eventually happen to me. I've had my 6t go to crash dump mode several times. A few times when I wasn't using my device and went to use it it was on crash dump and some other random times on various custom roms.

Crazy thing is every time I have been able to boot back to system by holding power + my volume +&- untill I see fastboot screen then release and every time I could hit start from bootloader and phone would reboot back to system like nothing ever happened. However this seems to be happening more and more as time goes on. Seeing how it's happened with some of you guys and you weren't bootloader unlocked or rooted just like if happened with @ms2020 then I would lean towards thinking this is a hardware issue and man if it is ... I remember when my Nexus 6p bit it. By the time they gave people some sort of refund on that it was probably more than a year later. I hope for all of us that that's not the case but it sure seems that way to me. ?

Are you thinking it was something in an OOS update? Possibly?

Whaaat, my OP 6 also went to crashdump mode like 2 or 3 times but got rebooted automatically soon after, never happened since.This was also around the time of August. man the part where you told abt your nexus 6p, it hit me. I also had the 6p and it suffered the same fate, sadly there was no support for the phone where i live and it's just lying dead in my drawer ever since. Just hope this doesn't happen again...

It's obviously a software issue after the latest update. My phone was never once dropped or exposed to moisture or charged with anything except the in box charger in the one year. There is no possiblity that mine was a hardware issue as OP suggests.

Sidenote: was any of your phones at less than 10% of storage remaining? My phone was below 10% odlf storage.

Also confirm your storage? 6/64 or 6/128? Mine was 6/64.

I have a similar problem, my OnePlus 6 is sometimes just freezing in the system, then shuts down and goes to CrashDump mode. I have this problem since half a year. Sometimes it just reboots normally.
What I also notices: When my phone shuts down because of low battery and I plug it in, it should enter the charging mode, where it shows the battery percentage and some animation, but mine goes into CrashDump Mode.

I had my 6t do same thing! Low battery, plugged it in and went to crash dump. When I get low battery again I'm going to see if I can make it do it again. I hope OnePlus can hook us up with a fix before more of our devices end up needing work done on them and are not able to be used because of it. So far I've been lucky enough to always get out of crash dump my holding volume +&- button and power down until I see fastboot screen and releasing then at bootloader screen just hit power and I reboot back in to system.

Op has gotta be right about this being software issue. I'm going to roll back on msm tool to a previous OOS. When I update from 9xx I'll stop a few OOS's before 10.3.5 and see if any of this occurs while on an earlier version of OOS. Worth a shot. I'll report back in this same post in a few days as to what OOS I'm on and if I have this low battery plug in crash dump or crash dump any other way.

Any update??

Just had another crash dump and "Attecomp" below where it said crash dump. My device is a T-Mobile model that's been converted to Global. Since I started flashing roms back in the Nexus S days I've always kept dev options on and usb debugging checked... Currently flashing OOS in twrp. Will report back if I boot up to system or whatever happens. I do know I had 65-70% battery when this happened. I was on Pixen Android 11 with no extra mods or anything installed at the time.

Six or seven times previous I've always been able to manually do the button press , enter fastboot mode, hit power and I would boot system. This time when I did that and it looped around back to crash dump mode again. So I manually booted twrp and waiting for it to finish flashing now... Fingers crossed. ?

I'm good. I did a clean twrp install of latest OOS 10.3.6, Corvus and finalize, formatted data and im back booted up now and setting up phone.

So this is the update. A person in my town had the same issue. Went to a local repair shop. They informed that its an issue of the IC. I think its jargon for the mobo in the local market. So they repaired his "IC" and apparently his phone is running fine now. Costed about 40USD. Will take it to them in a few days and report back. Still cant understand how its a hardware issue though.

Just read that crash dump happens due to a kernel issue on OnePlus 6/6t. Read that on a telegram group.

Also see this for details: https://github.com/Ashutosh-s-Test-...mmit/a7611e75d6b4262b22475e0e12a9ecf84cf5e443

This must mean that this is one way that crash dump occurs. Because not all crash dumps are the same. If so then how come I've been there 7-8 times and always gotten back to a working device by going to fastboot mode manually and rebooting system.

And some people are stuck in crash dump and cannot do anything about it.

Every time I've been to crash dump mode I could always do the manual button press to enter fastboot mode and then hot exit that and reboot system by selecting "start " using power button when it's at the bootloader mode. Except yesterday...

Yesterday I had just installed OOS and Pixen 11 and booted system and setup my phone. All was good and my battery was at 55%. Then I booted twrp to flash magisk debug for root and instead of rebooting system like I selected from twrp it went to crash dump and when I tried the usual solution instead of rebooting to system it looped around right back to crash dump again. I booted twrp and installed OOS + Corvus and formatted data and booted fine. ?
