I've got an issue where I think my OP6 is done, but better to ask here. Using latest lineage os 19.1 with mcd R16 kernel.
Today morning I was using my Oneplus 6 as usual, but later on it freezes then qualcomm crashdump mode appears. Well, not a single hardware combo keys recover the phone and didn't force it to reboot normally.. So I decided to do MSM tool with 10.3.8 firmware. Well, it has completed the process without issues. Phone was booting but in the middle of the booting logo animation it just freezes, did it four times or so and then crashdump again. So I did the whole MSM tool process again, now when the process was done, it want to reboot, oneplus logo appears with the powered by android then crashdump again.
Does it mean my OP6 is completly dead (like motheboard issue etc.) or is there any way to recover it?
I've sent it to the service center then: :/
Repair for 313 €, rejected, they will send it back.
Device returned unrepaired, I will sell it on parts
You can buy a whole motherboard on aliexpress and replace yours

Hello everyone,
I am brand new here and I have been searching for a solution to my current problem for over half a day now with no luck, and I'm hoping you guys could give me a definitive solution.
I am currently using a LGL22C (LG Power) Tracfone and I've come across a boot loop problem.
During the boot screen with the LG logo, I am presented with the following at the top left of the screen:
ERROR : boot certification verify
[450] ---------------------------------------------------------------
[450]
[450] Secure boot Error!
[450] Cause : boot certification verify
[450]
[450] ---------------------------------------------------------------
(Note: The boot loop continously restarts my phone while having 450 changing into 440 and vice-versa from time to time)
My phone was rooted via Kingroot and I've had it rooted for a little over 2 months. My phone is now in a bootloop due to the installation of Magisk v9. I accidentally installed it using Magisk Manager v2.1, which updated and installed everything that is "Magisk", which then prompt me to restart (which I did), and I'm now in this dilemma.
Again, I have searched for a solution for half a day and I did find some solutions that I thought would work, but unfortunately my phone can't:
1. Connect to my PC (No matter what I do, like update drivers)
2. LG Mobile Support Tool cannot detect nor support L22C model in its listing.
3. Doesn't have Emergency Mode, Download Mode, or Recovery Mode.
My phone CAN in fact go to Factory Reset, but that doesn't do anything in terms of solving my problem.
PLEASE I hope you can assist me. I am truly in a desperate situation.
Thank you!
UPDATE: I just tried to move my number to a different phone (LG Optimus Fuel) which I know that works for the time being. I deactivated it, added my other phone to the plan, but now it's affecting my other phone! I can somehow manage to get it to the Main Screen, but I can't uninstall anything, nor can I use the Phone app, because it states that my Contacts have stopped working (along with several other applications). My other phone has never done this before, nor did it have issues, but it started as soon as I tried to reactivate my number from my LG Power.
Sorry, this phone does not have any sort of recovery options if you trash the firmware. I am also the proud owner of a brick. I've ordered a replacement motherboard from eBay ($15) to perform a brain transplant, and then I'll have to start over.
I have this problem where phone randomly shuts down. It was fine until phone also stopped booting and getting stuck into fastboot mode. After this happened i had to visit repair shop. It works for few days and suddenly it again crashes and get stuck in fastboot mode.
I tried flashing with msm tool. it worked but after i updated to 9.0.5 and restarted it didn't boot again. Now flashing with msm tool isn't working as well but earlier it did.
So my two questions are:
1. why my phones keep crashing and stops booting?
2. Why msm tool is not working again when earlier it did?
Hello everyone,
I have a European H870 and unlocked the bootloader, used ADB/FASTBOOT to install TWRP but could never get to start in recovery because of a warning screen that shows up because it is unlocked.
Couldn't get into recovery from both ADB or by utilizing the keypress method. Vol-down+power --> logo --> release power for 1 sec then back on it. I even tried with other variants of that but could never get into recovery or DL mode. What's the point of unlocking the bootloader if you can't do anything afterwards because of a stoopid warning screen?
I never had that issue with my Samsung Mini S3. But with the LG's that I have, since the bootloaders were locked, the phones display this warning screen upon powering up. I can't be the only one with this issue unless I was doing it wrong. But I wasn't. So...anyway.
So with my G5 H850 I got around this problem by using FASTBOOT FLASH RECOVERY TWRP*.IMG and then FASTBOOT REBOOT before using ADB REBOOT RECOVERY during the boot process to get into recovery before the phone had fully booted.
So I tried the same with the G6 H870, of which I also cannot get into DL mode or recovery because of this screen. The only difference was that there is something different about how the H870 loads the system so that I could not run ADB commands until the phone was already 100% booted and thus rendering my recovery flash useless.
I ended up doing something that caused my phone to always boot into fastboot so I downloaded what I thought at the time was the correct boot.img and flashed it. And now I'm at the current situation where the phone boots past the warning screen and into the logo screen but then stops for a few minutes before rebooting. This process endlessly repeating. It is obvious to me that the boot.img was incorrect.
So what I have done so far is loading all Qualcomm drivers, LG drivers, QFIL and QPST (drivers being installed or uninstalled for each instance that requires them). The problem now is that the phone shows up on a COM port but is is unrecognized to all the different software and thus can I not communicate or flash anything to it.
A couple of unbricking procedures that I tried are:
https://forum.xda-developers.com/lg-g6/how-to/lg-g6-unbrick-method-t3935924
https://androidmtk.com/use-qpst-flash-tool
There were more but I cleared my browser's memory.
So, do I need to invest in an Octoplus device to get past this or is there another way?
Thank you.
Hi guys,
Hope someone can give me some light about diagnosing flash memo device hardware damage.
I have an OnePlus 6 A6003 that entered for sudden in CrashDump Mode. It stopped to run the OS, although the bootloader mode still worked.
Guided by some tutorials I tried to unlock trough fastboot and adb in CMD panel without success in unlocking the device.
After that, I started trying Msm Downloading tool to flash a Oxygen firmware and make it brand new. I couldn't.
The process stopped somehow in the middle of downloading to system_a. I lost hope big time here and went to SMT flashing. The tutorial advised that i could lose IMEI if i did not backed up my EFS. I didn't, but i figured i could use some downloaded backup and change my IMEI back to original, as I have the original box and data of the phone. I did it and the process of flashing the device stopped the same spot it did before.
From there I repeated the process in loop until finally I got it done. Once the original oxygen firmware was succefully flashed I was happy, till i discovered the phone still doesn't turn on. it always blurs the initial logo screen after some seconds and freezes.
At this point I think there is some hardware problem at the flashdrive device. Anyone have any idea if this still can be a software problem or can assure me how i could definitly diagnose it?
I 'd be thankful with any help.
Hi,
My oneplus 6 appears to have either died or bricked itself during the night, I got the qualcomm crash dump mode screen on my device when I woke up this morning. My device isn't Rooted or flashed. I have since discovering this this morning I have been panic trying to sort out a solution I have tried MSM that gets to the download complete status. I remove the cable the device displays a splash screen and the screen stays black. Going into fast boot the bootloader and baseband are blank. Hoping someone would have a solution.
Thanks in advance.
I have the exact same issue, I've tried multiple MSM tools without any luck. Sometimes I can reach Fastboot mode, but most of the time it seems to be stuck in EDL mode. My phone was unrooted and stock.
Yep, happened for me too.. Still figuring out to fix this issue.
