I don't know man. Already tried so many things to recover my Lumia 1020. Ended up buying a replacement motherboard. JTAG shops couldn't repair it. I had Win10 in it and it just crashed with the "can't find bootable option" error.
So I need replace a new emmc, if I replaced then flash FFU use wdrt or writ something to emmc?
I have a Lumia 920 (RM-821) and it instantly connects as a USB Input device, VID 05C6 PID F006. I tried to restore with WDRT - it doesn't see it at all. Trying to use thor2 for emergency mode - just quits when i try to assign a port. If I don't assign a port it will error out with
Anyone knows what am I doing wrong? I did it as the tutorial said but no luck, I tried to install qcom drivers but windows says "drivers are up to date".
Initiating emergency download
Operation took about 20.00 seconds.

Thank you very much!! I was struggling with my lumia 920 for 3 months and couldn't fix it until i applied the instructions. But i have a question. Sould i reattach the shield i took off to reach the r3209 resistor? Because that part of the phone gets hot easily.
Would recommend doing that definitely, plus put the copper heatsink on too. Now imagine me struggling with my 920 about it since 2015 xD
My lumia bricked when flash FFU by WPInternal.
Currently, WDRT couldn't help because My phone did not response when Holding Power + Vol down,
It is completely unresponsive, just a black screen.
I think I should try your guideline to force it to QHSUSB_DLOAD mode.
However, what makes me feel afraid is removing the heat sink @@

Ah, make sure to be careful, use a heating plate or a help from a service assistant. Definitely do the short trick.My lumia bricked when flash FFU by WPInternal.

hey man! i have made video on how to create emergency files for lumia devices like 650 , 540 here is the link if any one wanna unbrick their dead lumia from qh usb bulk mode downlaoding link of emergency fies is in the description without using any jtag or any other flashing tool u can repair ur dead phone and get it back to life
After 4 months i decided to unlock the bootloader and bricked my phone again lol. Even though I used the right engineering sbl3 or hex files, I made the phone think it was a lumia 950 in a way I don't know how . Now it's in qhsusb_dload mode but WDRT is showing it as RM-1104 and i can't flash with thor2.exe. The phone is at 0% right now. Should i try to recover it or leave it bricked?

8Wondering where I was? me too.
Long time has passed since the start of this post (almost 4 years to be exact), so I decided to finalize this finally and release the fully fledged guide. Interesting how this all got here just because me, a dumbass, formatted his Lumia 920 in Mass-Storage Mode in 2016.
So let's start.
First of all, make sure your device isn't in QHSUSB_DLOAD. After all if it is, you can just flash with WDRT or Thor2, and not spend so much time on that (see my video on how to recover from QHSUSB_DLOAD).
Step 1
Disassemble your Lumia. You can use online video guides or just a service manual, doesn't really matter.
Step 2
Find the schematics of your device, most if not all are available online, afterwards, find R3209 resistor, yes, that legendary resistor which will force the device to QHSUSB_DLOAD.
Step 3
After finding it in schematics, find it on your device, approximately, since it is most likely under a metal shield, once found the approximate location, remove the shielding with heat, or if you are like me, start cutting it like death is coming.
Step 4
Now the interesting part, reconnect your phone's battery, this will ensure the phone isn't in any sort of state and is powered off. After, short the resistor to ground and connect your phone to PC while shorting, wait 2 seconds and remove the short.
Step 5
Voila!
Take a look at my video on how to recover from QHSUSB_DLOAD, and recover your Lumia using it.1
Right, I get that.
My question is more about if you understand what is happening when you trigger it to cycle on this way?1
When you make the edl cable and hold the button while turning the lumia on, the cable works like a short jig. As in every device, the CPU is "starting" first, there's command that is implemented in the CPU that switches the device to EDL mode but in this case, as the boot is dead, it switches to Qualcomm F006 Mode in other words, Qualcomm Modem Mode, which is normal for hard bricked devices.
I read a guide about unbricking a DragonBoard 410c but it's done using some base firmware files which we don't have.1
[emoji16]Ah, geez, man!.. No comment, heh; but, had to -just- comment!! Pfft.
Not anymore though. Sold every one of them . Except one. Even sold all my prototypes...1
The first thing you want to do is to rescue your phone, it won't be more broken if you flash another Lumia 1020's efiesp.bin, after rescuing the phone, you can fully wipe everything and start over...
