[Q] How do you fix/solutions QHSUSB_BULK similar to the LG G2?

Sorry to be an annoyance to make another post about my hard bricked LG D851. I was wondering if there is the solution similar to the LG G2 that can unbrick my phone. Attempted:LGflashtools, download mode, powering on the device, etc. ALL FAILED. So if there is any solutions or links to download, I will be very thankful for your kindness

Lg G3 Bricked, no recovery, no download mode

hi guys, flashed the rom stock bumped v20i, I received an error in flash with wipe, I rebooted into recovery but does not go. i lost recovery and download mode (volume up and connected usb to pc does not turn on the device).
any solutions?

Same here, any on f460k korean version =/.

I am getting stuck oin bootloop so had to downgrade. Why can't you get to recovery with battery pull and volume down?

always boot certification security, on download mode and recovery =/ even when connect the usb cable.

Is your phone in Qualcomm QHSUSB__BULK mode?
If yes I recently got this problem on my D855 after getting an OTA update, it hardbricked, it will need to be boot repaired, the owner of the board diagnostics software is in the thread you got your software from, he restricted his software so that it will give the said error.
He charges 50 USD for repairing boot, I returned my phone to the seller, you should try the software in offline mode, i-e disconnect from the internet before launching the application, if it works then tell us, if not then probably the best option will be to ask the owner of this software for access.

The com port as in my thread just wanted to check in this post if anyone has any updates too as this one sounds very similar

I totally messed everything up (stuck with brick)

I am an idiot..
Long story short my LG-D852 RGS is showing as an LG-D857 in LG FlashTool and I am unable to flash the correct rom as I keep getting an error message:
"Download fail!! Device model is different"
I somehow flashed my D852 to a D857 while messing around, and now I can not find any way to recover to factory.
Anyone have any solutions that can rescue me from this bricked phone?! PLEASE

If you want some good help to recover your phone go to this thread and ask for help or ask even if it is possible since you flashed the wrong ROM.

Only way you can fix it is probably kick it into Qualcomm USB Loader 9008 mode

Yes I actually agree with that.
Here is the link to that thread which is actually closed but the OP of this thread here can have a good read and perhaps Google for the software to download.

I actually fixed it using a modified .DLL file that bypassed the model mismatch so I used it with the stock bell 5.0.1 and LG flash tool and it finally worked

Very glad you got it sorted. Another success story!

I am confident this phone is basically unbrickable, much like other LG devices I've had in the past

D851 converted to D850 looking for a way back

Hi guys;
So i bought a second hand unlocked D851 ( TMOBILE) with kitkat (cloudy rom) wanted to upgrade it to lolipop but i hard bricked it then used board diag program to bring it back to life but i extracted a d850 rom TOT since the d851 didnt work so now my lg g3 is at&t and permenantly locked ,been trying for a week now to unlocked it for nothing then I read somewhere in this forum that its easy to unlock the d851 using the tmobile app. so is there any way to change it back to D851.

Anyone has any idea?!!

1)What do you mean permanently locked...carrier/sim, mcafee security, something else? If it's carrier you can order a sim unlock code off of ebay for @$4.00 us, or use any other sim unlock services out there.
2)If you changed a d851 to a d850 using board diag and manually loading the partitions - then why not extract a d851 tot and do the same thing?

thank you for the reply.
1- its carrier unlock + i have no online wallet and i cant get one
2- thats what im looking for is there a way to manually load d851 partitions i mean when i loaded d850 partitions my phone was in dload mode ( hard bricked) do i have to hard unbrick now again?
by the way i can search for other carriers and i find mine under rat:GSM but i m unable to connect to it .

1) I don't know of a free way to get an unlock code, so if you can't order one you're probably stuck. Pay a friend who can order one for you?
2) If we're on the same page here and you previously used the board diag tool then that should work again. Hard brick usually shows up in your device manager as qualcomm 9008 instead of an lg device, so to get back to that condition you would have to open the phone up and short a pin -
follow the guide in the link I posted before and you should be good to go. I don't have links for any d851 tot files though...sorry, not my variant.

Unfortunately...I think so. If you were to try and use the lg flash tool and try and tot a d851 file into a d850 it'll probably throw some errors - model check, for ex - and won't flash. You can try and see for yourself if you'd like...here's a link for a couple tools; the 1st is kdz method, second is tot: https://forum.xda-developers.com/showthread.php?t=2785089
To brick it again follow guide I linked( https://forum.xda-developers.com/sprint-lg-g3/general/guide-fix-hard-brick-recovery-guide-t3132359), short that 2nd jtag pin in the pic for @5 seconds, plug in the usb, and it should go to qualcomm 9008. You already know how to do the rest as far as loading partitions and such, and if you don't the guide will tell you what to do.
Good luck :good:

Yeah....and?
Re-read your previous post where you asked if you'll have to brick it again.
I said yes, and gave you a link on how to do it. Did you read the link? My guess would be no, since the 1st 4 steps tell you how to brick it and enter qualcomm9008 mode.
You're on your own now. Good luck. And you're welcome for the time I spent trying to help you.

It's cool. Yes the guide is for already bricked phones, but what I was trying to say is since you have a functional phone rt now you're gonna have to brick it, and by brick it I mean qualcomm9008 mode, and that's what the 1st part of the guide shows you how to do by shorting out the pin. Once you get to Qualcomm mode you can then use the board diag tool and load your partitions that you extracted from the tot and hopefully get back to your original d851 phone and get back up and running. Does that make more sense?
Again...good luck

I hard bricked it again and then extracted another D851 tot and then loaded all the necessary partitions but the phone still on qload mode i copied the sbl1.mbm of the D850 and tried them with D851 partitions the phone revived but not in download mode.
I managed tp recover all partitions and the phone is on dowloading mode but still detected as d850 so i have the dll cross error everytime i try to flash a rom even with using the custon dll file.

Help [hardbricked device] urgent need of help asap

Ok so i was just rooting when my phone decides to die during so commands in adb. :crying:
Now i cant turn on the phone or boot into fastboot or bootloader. everytime i plug it in the charging light just flashes. Also my computer recognises the device as qualcomm hs-usb qdloader 9008 . ive read around the internet and ive found two methods. blank flash and qfil. issue is those tutorials were made for the moto g5 plus. I have searched around the internet and im beginnign to lose hope now. Can someone tell me how to fix this or give me the right blankflash version.
much appreciated

Im sorry that i cant post a useful reply for your problem that you cant even boot into fastboot / hardbricked phone.
The following link is for all those that are stuck in fastboot mode / boot loop.

if you cant access bootloader take it to a repair shop - you need specialist software and hardware to re-image your phone
how on earth did you do that - you do know to root this device its just a simple zip flashing in recovery mode - no fancy commands or anything required once you have unlocked the bootloader via the very easy to follow guide on the moto unlock bootloader website

If you are using LineageOS all you had to do was just go into dev settings switch root to disable & restart the phone
If you used magisk just use the magisk uninstaller then reflash the kernel
I don't understand why you touched the bootloader partition

I dunno y either. Luckily I had insurance on it so now I got a new device

Although even though I'm sorted it think we need a way to fix hardbricked devices because the Moto g5plus and g4s have fixes but I haven't found any that work for Cedric devices
