My G2H PRO is bricked

[Guizzan]

I had firmware 3.34 on my Aqara G2H PRO out of the box and I enabled telnet using this guide: https://github.com/Wh1terat/aQRootG3
After that I used this guide: https://github.com/niceboygithub/AqaraGateway to connect my camera to Home assistant and also enable rtsp.

I edited post_init.sh script like this:

#!/bin/bash
fw_manager.sh -r
fw_manager.sh -t -k
killall -9 mosquitto; /data/bin/mosquitto -d
pkill rtsp
rtsp &

Using this configuration one of my camera works perfectly but another one doesn't boot up (stuck on yellow light after powering up).
How can I recover my camera?
I tried to flash firmware (https://github.com/niceboygithub/AqaraCameraHubfw/tree/main/stock/G2HPro) using the guide provided here: https://github.com/wizardofozzie/aqara_g2hpro_hack but no luck...
