Bricked phone/Crashdump Mode - OnePlus 6T Questions & Answers

EDIT - I finally got it to connect!
I assume that I bricked my phone today. I've been trying to use the msm recovery tool and the program is not even recognizing my phone. When I plug in my phone to the pc you can hear the connection. I also tested it by trying to fastboot. Which once it is done fastbooting I get the crashdump mode. Can someone please help.

That's good news!

How did you do it? Please explain here stepwise bro so that it can help others.

LG E617G Will not turn on.

Hello everyone. Recently, I used this tutorial: http://forum.xda-developers.com/showthread.php?t=2392762 to obtain Cm11. What happened was when I tried to unlock the bootloader, and used adb commands to execute the files on my root. After I did reboot, the phone wouldn't turn on. No signs of life, can't boot into recovery mode. I've done the tutorial before on this phone, and I reverted back to stock. Now that I'm doing it again it won't work. I think it may be hardbricked. When I plug it into my PC, I can go to device manager and the PC will recognize it as a Qualcomm driver. I really want to fix this problem without needing to call LG or get repair for it. I looked at some tutorials and found this one: http://forum.cyanogenmod.org/topic/71825-hard-brick-to-hell-and-back-guide-to-recovery/ I'm not sure if this'll work for me. Can someone please provide me with some help with this situation.

You have to send your Lenovo K6 Power to Lenovo Service Centre and get your Motherboard replaced.
If your phone is in guarantee then you will get free replacement no matter if your phone is rooted but please don't tell about root to them otherwise they will charge money for your small mistake.
what happened?
Do a new install

Boss it seems that you have hard bricked your phone so it means it's first boot has been corrupted there is no chance as first boot is mandatory to flash any file, there are some tools like octopus, or Medusa box, they can repair your boot then the phone can be used its just an outside chance 5o get it in workable condition look for some person or Repairing person have this boot repairing gadget,
If this fails too or you have messed up very badly then, last option is mother board replacement, there is no software option to repair by yourself
Help please..!!!!
:crying:
Even I face the same problem...

Bricked A2017G

Hey Folks, i just bricked My Axon 7 some Days ago. It started randomly a reboot which i can't abort anymore. Everytime the Device get's a Charge does it start again. I can't enter TWRP or Fastboot (Reboots after a few Seconds). Same for the Flash Mode. It is now completely discharged and i don't know how to recover it. Any Ideas?
Think i can't fix this, but asking here don't hurts... :angel:
4th grade unbrick guide here in the Forums. That helped me after i cannot access any Mode. No Flash Mode, No EDL, No USB, No Qualcomm Loader. Axon 7 too.

Lol. I made a guide based on that one but updated, called DFU unbrick, because everybody had to read my comments there anyways to be able to do it. Not sure why everyone still uses the old one ?
@Miustone: If you want, you can try an EDL cable first. A lot of people say that they could get out of DFU that way. (assuming that you can get into EDL/DFU that is). Google my guide, it's called "DFU unbrick", if the EDL cable doesn't work
Thanks Guys! I will take a look on the DFU unbrick and the EDL Cable. At least a blink of Hope for this great Device... Still good as new, would be sad to use it just as a golden Sculpture lol

Hey, sorry for asking but how did you brick it? I am thinking about installing a custom ROM, rooting etc and I would just like to know if it was something in specific so I can stay away from it. Cheers.

after rooting and unlocking bootloader my PC won't recognize my phone through ADB

TWRP is still installed and magisk as well, but now it's not rooted and the bootloader is still locked. I am so confused about how this happened, does anyone have any ideas why this happened, or what I can do to repair it? The phone still works but it won't update and it's a little wonky. msm download tool doesn't even recognize it. thank you for any help!
EDIT: now it won't boot up to anything, only boots into the bootloader, won't go into recovery or anything. please help! haha
msmdownload tool, grab the one fitting to your phone, see in Guide News section
The msmtool won't even recognize it, that was the first thing I tried
RMA
I faced a similar issue but I was able to get it working through the MSM tool. Make sure you are holding the volume up and volume down for 15 seconds before connecting it to MSM. It should work if you follow the guide.

Hardbricked to Qualcomm USB 9008

Really hoping someone can help me out here. I have a Nexus 6P, Non-BLOD. Yesterday, after clean flashing the latest version of EvoX, while setting some things up, device randomly crashed. No Shut down animation or anything. Just black screen. Tried turning it on via Power Button and then Power And Volume Buttons but nothing works. Connected it to PC and see it's Detected as Qualcomm USB Bulk (9008) in Coms and Ports. Did some research and found out I have to flash via QFIL. And this is where I am stuck. I tried several versions, but it doesn't flash/gives Shara error. I tried reinstalling driver. I also read a guide here. But the Firmware link is dead and it says to flash via MiFlash, something I can't even try since the Link in the OP is dead. I tried some different versions of QFIL but all of them give a Sahara Communication error. Now I'm pretty much at a loss on what to do. I'd really like to fix my 6P. And I would appreciate anyone taking the time to point me in the right direction, or help me fix it. Thanks in Advance.

Same thing happened to me in the same ROM (Weird) .. but i managed to flash the qfil successfully .. but still phone doesnt boot up .. here's what you should do ... try to hard reset the phone until you hear the disconnecting sound from pc . Ready all the necessary flash in the qfil and as soon as u hear the device connected hit the download button .. it will flash without the sahara protocol error . Be quick ! tell me if that fixed ur problem . Peace

Thanks. Can you share the files you used please? I can't for the life of me, find the correct download files. There was a Nexus6P_Unbrick by TenFar but all the links are down.

I used another qfil firmware
https://drive.google.com/file/d/1PixuumVVzxBKUsQ88X3AJ21Hsi2mV3Zq/view
Here is the link .. you can find the firehose and all files in the firmare folder . Best of Luck
I have a similar situation where I am unable to power on the phone in any way, and I am only able to communicate with the qualcom USB 9008 driver.
I am following your instructions using the firmware files you provided (thank you!) and I can see an attempt is being made to download the files before sahara error occurs.
I don't think I enabled developer options when my Nexus 6P was working and wondered if sahara error is due to that.
I was wondering if you had previously enabled developer options by tapping on the build number several times, once the operating system booted and if that is a critical step in being able to recover the Nexus 6p from this hard bricked state where I am stuck in EDL 9008 mode, and unable to access bootloader, and volume+power keys do not do anything...I feel like I'm screwed (and already moved on) but using time these days to learn about android devices!
thanks!
