OnePlus 7T Qualcomm Crash Handler Fastboot Bootloop​

disclaimer - I am brand new to forum posting and etiquette. Bear with me I'm here to learn not to get burned. thanks! also, I posted this in the main general discussion thread by accident, not realizing that there was one specifically for one. plus I'm a noob so if anyone wants to report it as a duplicate that would be appreciated. I can't figure out how to delete it.

I've been trying to unbreak my OnePlus 7T. I probably put about 15-20 hours in the last 3 or 4 days into forum reading, running fast food commands and running my fingers through my hair and binge drinking..jk. But right now I'm at my wits end. here's where I stand. I've got into it to boot into twrp for about a day and then I flashed the wrong thing to the wrong place I believe and it give me this really scary black screen with Chinese and English on it saying that I destroyed my boot and recovery images. I was able to to get past that screen only to get it to be stuck in a permanent fastboot screen boot loop where it's not even giving me the OnePlus logo before it boots in the fastboot it just immediately boots back to the bootloader screen. I can still run fast food commands be my command prompt this is where I'm at with it.

through my grand deductions I figured I would run fastboot getvar all this was the response.

I'm hoping with this information somebody can tell me WTF I have done wrong and what I can do to fix it. here's what I think is going on is that I corrpletely destroyed the partitions. I noticed that under a lot of the partitions there's _raw. which makes me think that it needs to be formatted somehow or repartitioned. I have no idea. like I said I'm at my wits end here. I have flashed boot images and recovery images and I don't even think the phone knows it's a phone anymore lol. so I was actually in TWRP for a hot minute but in the process of trial and error got myself where I am now. I'm going nuts over here. running fastboot commands. hopefully someone can throw me a bone and give me some guidance on what I need to do to get it right. thanks y'all
