[Q] Phone bricked, no download mode. Please help.

Hello,
I've looked for solutions everywhere and have spent the last days trying to fix my phone but i can't find a solution. Here is my problem:
I bought a second hand phone, it was working fine however it had been rooted and was running on Cyanogen.
I therefore tried to revert this to a stock EU ROM I downloaded. I was able to do this through the LGMobile Support Tool.
However when the process completed, my phone was stuck in a reboot loop on the LG logo. So I went back to the LGMobile Support Tool and selected 'Upgrade Recovery'.
After completing this, my phone was still stuck on the loop, but now I'm unable to access download mode, or recovery mode.
My phone is detected in device manager as LGE AndroidNet USB Serial Port (COM4) and LGE AndroidNet USB Modem when plugged in.
I don't know what to do? Please help.

This is now resolved thanks to bender_007

Try wiping through stock recovery mode (hold volume down and power, wait for lg logo then hold volume up and volume down-without power button)

Blackscreen / Qualcomm HS-USB QDLloader 9008

Hey guys,
finally i bricked my phone...
After a failed flash to TWRP recovery and a failed unbrick with fastboot, the phone won't start. Blackscreen. Only in device manager it show's "Qualcomm HS-USB QDLoader 9008". Is there any chance to unbrick or should i get a new mainboard?
PS: Sorry for my bad english, im from Germany
Thank you in advance
JaDa

@JaDaKiZz welcome to the party - read this http://www.reddit.com/r/lgg2/comments/2p5xei/the_lg_g2_is_unbrickable_a_story_of_death_and/ and let me know if you need any help. The MOST IMPORTANT thing you need to do is figure out the right KDZ for your phone.
Use http://csmg.lgmobile.com:9002/csmg/b2c/client/auth_model_check2.jsp?esn=xxxxxxxxxxxxxxx
replace xxxxxxxxxxxxxxx with your IMEI

Hey sandys,
the BoardDiag start but abort the test.
Linux don't show my G2 in devices. What can I do?

Same thing happened to my phone. Thats what it shows in windows and isnt picked up by ubuntu. When I tried to use the lg tool to recovery it fails and says phone isnt in dload mode trying flash programmer. Dont have the money currently for @tungkick and dont see any other way.

Chinese Axon 7 is not seen in ADB or MiFlash..Bricked??

After installing twrp on my chinese axon 7 latest B16 I rebooted accidentally and now my phone gets stuck on the the ZTE logo.
I cant enter recovery as when I press volume up + power, it reboots a couple of times with the zte logo and nothing else.
Also when entering EDL mode the only thing my PC is showing in device manager is "Handset Diagnostic Interface(DFU) (COM6)". Before it was showing as "Qualcomm HS-USB QDLoader 9008" but no more, even after multiple reboots and installing the qualcomm drivers again.
Before when running "adb devices" in the CLI I would see my device but now nothing. and running adb reboot edl shows error: no devices/emulators found.
Also tried MiFlash but when I hit refresh I dont even see COM in the list, its just blank.
Does anyone have any suggestions?
as I tried the below guide but get stuck as my device is never picked up by ADB or MiFlash

Yeah, DFU brick. You basically need to follow the 4th category brick repair guide. Good luck

wow damn..I found this guide: https://forum.xda-developers.com/axon-7/how-to/a2017-4th-category-brick-repair-manual-t3585898
But I see it involves me opening the device which I am trying to avoid as a last resort.
I just sent the seller from Ali-express to see if they will replace it.
Never actually told them that I was tinkering with it.
Fingers crossed on the reply, will update the thread once I receive a reply.

well that's the other way lol
I had to follow the guide, and it fixed my phone, so be assured that you can fix it if they send it back

It seems I got really luck as putting my phone in Factory test mode made device manager finally show "Qualcomm HS-USB QDLoader 9008" which I was then led MiFlash in detecting it.
I was then able to flash Stock B13 and from there unlock the bootloader, flash twrp and root.

Usually you can't enter Factory Test Mode when on a DFU brick. The known procedure to do that is to discharge the phone, then put it into FTM somehow and then using ADB to get to EDL. It's really weird that you've been able to pull that off that way
Could you tell us how you got into FTM? Just by vol down and power? It would be a nice addition to the brick guide, before attempting to take the phone apart

Yeah, it was just by power + volume down.

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...

You can restore you device using fastboot rom. Search for oos 6t fastboot rom.. There are guides for installation.
P.S. It will give a whole bunch of error in the cmd during installation but don't interrupt the process as your device will be restored in the end

Use Mnm tool to fix your phone. It can fix hard brick devices and guidance is there how to use .
PS: this is not right place post next time post on Q/A section.

Hold all the buttons down till it shuts off, almost a full minute. Then get it to boot to fastboot, power off. Then start up msm, then while phone is unplugged and off, hold both vol buttons for a 4 count, then plug it in. Msm will day connected, hit start. Let it finish and reboot. that's all

Qualcomm crashdump is not the same as download mode, and will not work with MSM. You still need to put your device manually into download mode.

Hold down every button till it shuts off, then force reboot to bootloader, then select power off to make sure it's off. Then do as I instructed above to fix it. Sometimes u can just run a fastboot rom to fix it, or boot twrp and flash a rom. I do this multiple times a day sometimes.

Thanks everyone who replied. The whole thing started when I tried to update my TWRP the wrong way and I got nothing better to do. I was on 3.2.3-1 and the newest on the website (TWRP) was 3.2.3-2, but I flashed the image instead, into vendor. This got me into the Qualcomm CrashDump Mode and it kept on rebooting to it as well. There was no way that I was be able to use the MSMDownload tool to recover my 6T as the tool couldn't detect my device as it was connected as Qualcomm HS-USB Diagnostics 900E not Qualcomm HS-USB QDloader 9008.
I pressed all the buttons and got into FASTBOOT mode! Then I booted TWRP, luckily all my stuff isn't corrupted and I did a Nandroid backup beforehand as well. So, I just restored my Nandroid backup and voila I got my 6T back. Thanks again everyone

Everybody, it's called the MSMDownload Tool. It cannot be used in Fastboot Mode or Qualcomm CrashDump Mode, it can only be used in EDL Mode (Emergency Download Mode).

If your using windows search for device manager to see what your device is being detected as. Try and reboot if your device isn't Qualcomm HS-USB QDloader 9008. Once it shows that try and update the driver, but you'll need to be a admin. Have you installed Oneplus USB Drivers?

Help I can not get in to fastboot mode. Im stuck in Crashdump mode. Even when i power off the phone holding powerbutton down for a while it will powerup again and the unlocked bootloader warning window with "press power key to pause boot" will not react to any presses.
Also booting and holding down power+down will result in the same and go to crashdump mode.
What do I do
