Fastboot Flash Firmware?

[M3drvr]

I was curious, is there anyway to flash the firmware and modem through fastboot instead of TWRP? I accidentally downloaded the OP3 firmware instead of OP3T and then flashed it and well you know how that goes. Thankfully this phone almost impossible to brick even when doing the worst. It shows up in the computer and my bootloader is unlocked, and i was wondering, instead of losing everything and following the unbrick guide if there are actually commands or ways to flash it through fastboot so i don't have to fully wipe the phone? I have TWRP backups that are from yesterday on the phone, so if there was a way to restore that at the very least if i did have to do the full flash then thats fine too. I guess if the unbrick tool didn't wipe out internal storage or something thats fine. Any help is appreciated.

If you're experienced, you can actually flash each individual partition image file back to each partition on your phone using fastboot flash file partition. So yes, if you know what you're doing you could just restore the firmware partitions and you should be back on track. However if you accidentally flash to the wrong partitions you could potentially brick your phone. ?

I'm perfectly comfortable flashing partitions. Done it many times with old HTC's and Nexus's. I just need to know what the actual names of the files are that i'd need to extract from the zips is the other thing.

Well, I've never really had to do this on the 3t. Last was on an old Huawei mediapad, but you can Google all the partition dumps in the latest full OTA zip, some are self explaining.

With the unbrick tool in the general section.
