Cannot flash debian

I’ve followed the instructions accordingly by copying the qdl from

Qualcomm_Device_Loader.Core.2.3.4.All-AnyCPU-qdl_2.3.4/qdl_2.3.4/QDL_Linux_x64

but it exits immediately as below:

s0001734@u5cg4493h3v:~/Downloads/FlatBuild_RUBIKPi-3_xx.xx_Debian13.R.debug.ES.r000001/ufs$ sudo ./qdl --storage ufs prog_firehose_ddr.elf rawprogram*.xml patch*.xml --debug
USB: using out-chunk-size of 1048576

I’ve confirmed via lsusb that I can see the device correctly:

Bus 001 Device 010: ID 05c6:9008 Qualcomm, Inc. Gobi Wireless Modem (QDL mode)

Dear customer,
We are currently syncing this issue internally.

Dear customer,
Are you currently using Ubuntu 18.04?
Please run the following commands prior to initiating the flashing procedure.
sudo modprobe qcserial
sudo udevadm control --reload-rules

Dear customer,
If the aforementioned commands do not resolve your issue, please run the following command:
sudo systemctl stop ModemManager

I am on Ubuntu 24, and

sudo modprobe qcserial
sudo udevadm control --reload-rules

did the trick, thanks. Please consider updating the documents in Get Started | RUBIK Pi Documentation

Dear customer,
Okay, thank you for your response.
