Ive nuked CrowPanel 3.5 HMI Please help need default firmware and bootloader

Bart_SwiatlLnuksa

Hi. I don't know if I'm in the right section - if so, I apologize for the mistake.
I have CrowPanel HMI 3.5'' rp2040. I'm just entering the world of pico and I broke the board... I uploaded various programs, finally I inserted some "loop" and to exit it I used the nuke all.udf I found... it deleted everything, including the factory demo and probably the boot loader. Full hard reset i think
Now my TFT lessons don't work:
lesson 3 - the screen lights up gray and that's it...
lesson 4 - there is an image but the stylus coordinates are wrong - I touch the left and draw somewhere to the right (
lesson 5 - shows the title business card - touch doesn't work (
How to upload the original firmware and from where to download it? I need to make a promotional video on YT for Elecrow and I'm grounded (((
I use Linux Open Suse Leap 15.6, I also have Mint 22, if anything I can install a different one - Windows is not available. Using Arduino IDE v2.
Thank you very much for all your help - I'm very new to the subject

Bart look at this post

ES32-wroom 2.8 in display will not program again

GPIO 12 is causing the problem and this post shows how to fix it setting esp32 fuses to permanently power the flash with 3.3 volts

It sounds like you’ve wiped the CrowPanel, including its demo and possibly the bootloader. Don’t worry, you can recover it.

1. Re-flash the Bootloader: Download the RP2040 UF2 bootloader from the CrowPanel or Raspberry Pi website.
2. Put the Board into Bootloader Mode: Hold down the BOOTSEL button on the CrowPanel while connecting it to your PC via USB. Release the button once connected.
3. Re-upload the Factory Demo: If available, download the demo file from the CrowPanel support page and load it onto the device as you did with the bootloader.

Check CrowPanel’s documentation or support for exact recovery steps tailored to your board.> @Bart_SwiatlLnuksa said:

If you've erased the firmware and bootloader on your CrowPanel 3.5 HMI, check the manufacturer's website or support forums for recovery files. You may also need to contact their customer support for official firmware restoration. Let me know if you need help finding resources!
