Thingy:91 Bricked after following "Getting Started" guide video

[Pinestudio]

Hi!
I've recently received my Thingy:91 and wanted to get it up and running. I followed your video (https://www.youtube.com/watch?v=xQ7hDzRULJQ), although did not see the description before completing the steps. I updated the modem firmware (turning on thingy:91 while holding SW3 and flashing it with the modem zip file from precompiled downloads section), then with lte-m asset tracker, and then flashed nRF52840 with connectivity bridge hex (SW4 button held while turning power on). Now, I cannot do anything with the thingy. I can get it to boot to MCUBoot for nRF52840 (SW4), but no matter what I do, I cannot see the 9160 in nRF Connect Programmer tool. It's completely dead. No LED, no characteristic "device plugged in" sound on windows when i try to boot while holding SW3, nothing. Is there any way to un-brick it?

Hi Andrzej, sorry about the delay.

Could you tell me what version of the Thingy91 you are using?

Hi Elfving!
Do you have any information on how I could fix the issue? I'm really looking forward to prototyping my solution using nRF91, and would love to get started.

Hello Andrzej,

I wanted to reproduce this, but haven't managed to.

If you try to follow the instructions here, I assume then you would have trouble with step 4? Let me know at what point you are running into issues.

Working without an external debugger / programmer can be a bit troublesome at times. Do you happen to have a 9160DK on hand as well? With a 9160DK and a 10-pin SWD cable this could be easily fixed, otherwise I am not so sure.
