Okey! One thing I found curious is that SW2 switch was in ON position when I opened it to follow the tutorial (the drone was brand new) (the switch to force the RB5 Flight into EDL mode). Do you think that could have caused some of the issues I reported in the beginning?

Is there any way to force into fastboot mode without the button? (through adb or some another option?) I am able to have wifi in the board in this mode (before flashing)

Also I tried to follow this page https://docs.modalai.com/Qualcomm-Flight-RB5-QDL/ I have a couple of questions: I found that the SW2 switch was already in ON position below the Quectel, and I think it should be off seeing this tutorial? by doing this tutorial I was able to see the board in ADB devices, but I cannot force into fastboot even with the button; when I try to install the image, the ./install.sh stops here:

marta@marta:~/Downloads/rb5_platform_0.9$ ./install.sh
[INFO] adb installed
[INFO] fastboot installed
----Starting System Image Flash----
Detected OS: Linux

Installer Version: 0.8
Image Version: 1.4.1
[INFO] Found adb device, rebooting to fastboot

here stops and keeps here forever

for the fastboot I followed this tutorial: https://docs.modalai.com/Qualcomm-Flight-RB5-system-image/

yes, seems like a power issue, but I just plugged/unplugged the USB to connect to the drone. I tried also with a different wire and different power and keeps happening the same. I tried to reflash the image to see if I could connect to ADB but it does not get into fastboot mode (I tried to force into fastboot) but it does not appear neither in ADB or fastboot

I cannot access through ADB or Fastboot to the RB5. I was able to do so, suddenly the Spektrum RC receiver and the GPS do not power on and also I cannot access through ADB. The RC receiver tries to power on at first but after 1s the blue LED's stops doing lights. I tried to power the RB5 with a fully charged battery and trhough the AC power adapter also. Sometimes it lets me open with ADB but it loses connection after 3 min.
