Pinephone pro stuck while booting

[Supervisor]

So i have a pinephone pro and i have tried every thing provided here https://forum.pine64.org/showthread.php?tid=18216 and gotten assistanve on discord which still did not help. Ive charged for approximately 10 hours on Maskrom, tried using a sd card, flashed directly to EMMC, attempted to reinstall Towboot, Used a gui tool and dd, and still it will not work. Whenever i turn it on with a working os installed it will flash red then yellow then stay stuck, the screen wont even show anything. If i try without an os on the phone it reboots as the it knows there no os installed. Sometimes too when i turn it on it will stay red and just vibrate as soon as it is turned on. It will not even boot to an SD card if i use either the RE button or the volume down button. I can however boot into mass storage mode by holding volume up and connect it to the computer, im not sure how much this can help but if anyone can help pls do.
