thingy:53 I have damage to the sw2 pin and I am unable to enter the DFU

[neuberfran]

Hi,

I have thingy:53 and I have damage to the sw2 pin and I am unable to enter the DFU. I lost two tiny pieces that go just above the one in the photo and not even using a needle, it seems to me that the button (which was not working before) now doesn't work anymore

My question is: What would be another way in the circuit to put sw2 under pressure (while I throw sw1 to ON) other than pressing this "button"

I stay trying this: https://academy.nordicsemi.com/flash-instructions-for-the-thingy53/  (USB-C Mode)

Note01: I still have the two tiny pieces that came off the top of the sw2, but I don't know how to solder them back and I don't even know if that would solve the problem.

Hi,

So the button push doesn't out the device back into DFU mode at all? I thought you meant that with the button broken it was now difficult or not possible to put the thingy into DFU mode, but it sound now that maybe something else might be wrong in addition and that the DFU functionality isn't possible to recover anymore for some reason? Have you connected a programmer to the thingy in some way? What was the last FW update you did across DFU and was it successful?

Best regards

" maybe something else might be wrong in addition and that the DFU functionality isn't possible to recover anymore for some reason? " Maybe.

" Have you connected a programmer to the thingy in some way? " I have mini edu debugger segger from adafruit and I have access in thingy53 from it (mini edu jlink). 

From Year Ago I used thingy53 with segger mini edu

Do you still have the Segger device? That could be used for programming the thingy. If not, then if for some reason you have one of our development kits, they could also be used to program the Thingy if for some reason the bootload is erased or not recoverable.

I need video or something else that shows this: steps: 1) I press the sw2 button, 2) with sw2 pressed I change the switch from Off to On, 3) Always with the nrf connect desktop open, but I never see the Bootloader_thingy53, Working. Excuse my incredulity

[Asbjørn]

Hello,

It seems like you've had your attempt at replacing the button, but if the device isn't going into bootloader mode it could be that the bootload is lost or damaged as well as part of all of this. I'd encourage you to find a programmer and connect it to the thingy53 and reprogram the bootload if that's the preferred way to interact with it or use the Segger programmer to just program it all in all.

As you can see in the video above, I have some news.

I followed this video and made the blink led(using JLink Mini Edu):

https://www.youtube.com/watch?v=qNQ7tH7vga0&t=567s

Next, I changed PC, removed the JLink mini edu connections and connected the USB cable (without even pressing sw2) and thingy53 finally appeared on that screen (nrf connect for desktop -> Programmer) 

Then I uploaded and wrote the dfu_application.zip(blink led app) and the rest is in the video I posted at the beginning of this answer.

The questions that remain are:

1) What if I had bought the thingy53 today and didn't have the JLink Mini Edu?

2) Why didn't I have to press sw2 when I changed sw1 from off to on?

note-01:

I need to rectify this post above (as per photo below) since I had to press sw2 to burn the firmware (Phew! I entered Bootloader mode) on the nordic thingy53 for edge impulse and now I have a new problem (both using USB-C and using JLing Mini Edu) the firmware for thingy53 for edge impulse is outdated for zephyr 3.7.99)
