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

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
