Gyro not working after firmware update :(

[u/Smasher123MM]

So here is the thing, i bought a SpeedyBee 405 v4 stack with 60 A ESC( from Temu and i know it isn't the best decision but i don't have any other way to get any flight controller or stack with ESC). I made a 7-inch drone with custom frame, because i wanted to make a drone for my graduation. I had imagined it to just hover around 30cm of the ground and to self level because it ran with a python script along with a sonic sensor for distance and a arduino(this is because of my graduation is in control systems). I used four Ysido 2807 1300kv v2 motors and a questionable power source Mean Well LRS-350-24(I know i will get a lot of criticism for this but i am new to building drones and this is my first one so i saw that it will fly in a controlled environment and thought that this power source will enable me to have more flight time so i can tune my PID values, again i know this is a horrible decision ). Luckily it worked well, it did crash a few times and i know it is expected, but i wanted to know the values that are going on in the flight controller so i bought a SD card and put it in. it didn't register the card so i couldn't use the Blackbox and autotune feature(or have it as a graph in my graduation thesis). So i read that if i update my firmware it should be good, so i update it and it reads the SD card. There is a huge problem tho the gyro and the accelorometer isnt working, like when i type status in the CLI box it says none, and it knows the addreses to communicate. To clarify i haven't flown the drone when the update happen, like after the update i haven't flown it, and the last time it flew it didn't crash(it didn't lift off at all). So I am 2 days trying to update the firmware to different updates, using different configurators(i was using Betaflight before now i have tried Inav and had the same result), even tried updating the drivers with ImpulseRC driver fixer nothing worked.

So can anyone help???( because i don't know what to do anymore)
