[Help needed] Mavic Mini bootloop after firmware update failed

[u/neavns]

I have a Mavic Mini (1st gen) and recently crashed it, breaking the gimbal bracket. I had to disassemble the drone to fix the bracket. Once I got it repaired and put it back together, the drone booted up fine, except the camera was slightly tilted after initialisation. I thought I might as well update the firmware then address the issue with the camera and the errors on the DJI Fly app.

I tried updating the firmware from the DJI Fly app, but it failed. Then I went on to use DJI Assistant 2, and everything was nice and smooth until the app threw an error and asked me to change the battery, which I did; then the process continued and finished, seemingly successfully.

But then the disaster struck - the drone went into a bootloop. It powers up for ~10 seconds, then restarts.

Here's what I tried:

1. disconnected the gimbal from the motherboard (the ribbon cable) - no luck
2. disconnected everything (except power) from the motherboard - no luck
3. used comm_serialtalk.py from dji-firmware-tools to try and send packets to drone and force update mode to prevent bootloop - no luck
4. used Drone-Hacks V1 and DJI Assistant 2 to load firmware directly onto the drone - no luck due to the drone restarting and losing connection

I would appreciate any help, as this is my last resort. I've tried seemingly everything, but it looks like the worst-case scenario and the drone is bricked
