[Nokia 7.1 Questions & Answers] weslowsk:
interesting ... thanks @mortemonline

I'm going to walk through the steps you did and compare them to what I did or what I will do and see if I've got things straight...

1) Install QDL

- I've already done this.

2) CD to firmware folder

- No problem.

3) Run QDL

- From my earlier post

I think I have the syntax right and it's similar to what you have:

sudo /home/kevin/HDD1/git/android/Qualcomm/qdl/qdl --debug --include '/mnt/HDD1/temp/FIHSW_CTL-415C-0-00WW-B03_600WW_10_20200501.full.lzma2.786e65af1f0e0b8bb0077f8de8e2b3ed8190435e0f8c1b0031b7ec90abd5785c' '/mnt/HDD1/temp/FIHSW_CTL-415C-0-00WW-B03_600WW_10_20200501.full.lzma2.786e65af1f0e0b8bb0077f8de8e2b3ed8190435e0f8c1b0031b7ec90abd5785c/B2N-0-415C-prog_emmc_ufs_firehose_Sdm660_ddr.elf' '/mnt/HDD1/temp/FIHSW_CTL-415C-0-00WW-B03_600WW_10_20200501.full.lzma2.786e65af1f0e0b8bb0077f8de8e2b3ed8190435e0f8c1b0031b7ec90abd5785c/B2N-1-415C-rawprogram0.xml' '/mnt/HDD1/temp/FIHSW_CTL-415C-0-00WW-B03_600WW_10_20200501.full.lzma2.786e65af1f0e0b8bb0077f8de8e2b3ed8190435e0f8c1b0031b7ec90abd5785c/B2N-1-415C-patch0.xml'

The first parameter is the prog/emmc/firehose/ddr file. As I noted in my post, I don't have a .mbn file that looks like that in my firmware folder and the closest one is a .elf file. So, that's why I have that. Or, should I be reverting to the original .mbn file I tried that didn't give me much response earlier?

I also have the rawprogram and patch xml files as the second and third parameters.

So, I assume I run it at this point? You didn't say so but I assume I need to have the phone plugged into the computer via the USB cable, right? And the battery is connected at this point?

4) Unplug battery

- Ok, I can do this again. It's a hassle but if it's necessary, no problem.

- So, I have to unplug the battery while it's connected to the computer? That doesn't seem right, easy, or safe. Please advise.

5) Short circuit / USB cable

- I don't have an edl cable.

- So, at this point the battery is unplugged, as indicated in the previous step.

- I also assume it's not connected to the computer at this point. Please confirm.

- Short circuit. I need some guidance here ... I've never done this before. The red circle on your post/image https://xdaforums.com/t/nokia-7-1-bricked-advice.4221393/post-84888087

is a square metal contact point. What do I do to it?

I found a conflicting article about the test point for a Nokia 7.1, though:

{Mod edit: Link to paid services website removed. Oswald Boelcke, Senior Moderator}

The arrows in that diagram show it's the third and fourth circle metal contact points way to the left of the square metal contact point you're referring to in your diagram. Which is it?

Do I just touch both points simultaneously with a pair of tweezers or 2 ends of a paper clip or something like that?

Then, I connect the phone to the computer via a USB cable? Do I do that while I'm doing the short circuiting and then stop short circuiting after the USB connection is made?

Sorry, but I'm not quite following all the advice/steps so far...I'll need some more handholding.
