broken tow-boot

[hashkeeper]

Hello everyone. I think I ran into an infinite loop with my device. I believe I installed towboot on my pro device (i have a normal pinephone too) years ago. It seems to be broken. When I turn it on I get a steady red light (good, it has power), then a yellow steady light, then red blinking lights (very bad). If I turn it on and into usb debugging/flashing mode by holding down the volume up button down while the phone boots up, I get red, blue, into yellow and red flashing lights. Luckily, I can still boot into jumpdrive and expose the eMMC.. it seems this is not the right way to flash images to this device however. This is an old pinephone pro, one that came out after the explorers edition. It doesn't have an RE button that you hold down to boot off the sd card first.
My question is: how can i reflash towboot to the phone either using telnet or jumdrive? the usb debug mode, as I've said, seems to be corrupted because towboot seems to be corrupted. If it's a matter of not being able to boot off the sd card into the towboot installation wizard because the phone is so old, does anyone know which contact pins i need to short out to boot off the sd card instead? I researched and could not find that information out.
Thank you in advance

To fix your PinePhone Pro, download the correct Tow-Boot image and reflash it to the eMMC using Jumpdrive and a flashing tool like `dd` or Balena Etcher. If SD card booting is required, you may need to short boot priority pins; check Pine64’s Wiki or forums for the exact process. Once Tow-Boot is restored, boot from an SD card to reinstall your OS.
