Pinephone Pro wont boot to anything!

[Supervisor]

So i have a pinephone pro here and i tried turning it on after like a year of not using it. The battery was obviously drained so i charged it for 6 hours on maskrom mode to my mac. After trying to turn it on, the led turns red, then yellow, but then stay there. Ive tried flashing oses to the EMMC and a 16gb SD card and also tried reinstalling towboot using the exact instructions provided, ive tried both sp.installer.img and shared disk methods for that. Ive already followed these instructions:
