Unclear exactly what you intend to do.
You can find firmware for your device at https://www.huaweiflashfiles.com/
Maybe a far better place to ask regarding router is Huawei or open wrt forums.
I hard bricked my TP Link router trying to install open firmware, that is supposedly
an easy job. be carefulHi, thx in advance for you time and help and sorry for mi bad english.
I install antix in virtualbox , I already soldered the cables and the connection is ok under W7,
but newby in linux
need make a backup firmware router with a CH341a black edition in TTL mode.
need check if ok the connection under antix 1A86:5523 [0304] ??
(in VirtualBox read QinHeng Electronics CH341 in Serial mode, usb to serial port)
need install driver to CH341a ??need instructions to run script rt63365tool.py, please any help is good for me…
Xecure
Please, link the tutorial you are trying to follow. We have no idea what you want to do and antiX is not a router OS, so we don’t have experience with what you are trying to do. There most be a set of instructions you are trying to follow, and decided to do this on a lightweight linux distro, but people who use linux don’t know everything, and we cannot understand what you are trying to do without context. Are you following a openwrt tutorial, as Moddit points out, to backup the router’s firmware? Cannot this be done in the Windows terminal? Why do you need to do it on linux, because it says so on the tutorial you are following?

General Live Boot Parameters for antiX.Please, link the tutorial you are trying to follow.
And exact make and model of router not just the usb to serial adapter..
What you gave HG532s points to a Huawei model for which firmware is available so I assumed
no need to backup.Maybe https://github.com/matthiasbock/linux-i2c-ch341 can help you to prepare a kernel module
for your USB to serial adapterI see no reason why linux should not be usable, may not be easy though as we have no equipment
to replicate your work and it is outside of anything most of us have tried. You really need to
ask some experts.Xecure
Thanks for the link.
Requirements mentioned in the tutorial:
Requisitos:
Adaptador de puerto serie TTL para conectar al router, y saber manejarlo mĂnimamente
Cliente TFTP en nuestro ordenador. En esta guĂa usamos un ordenador con sistema operativo GNU/Linux, aunque no es obligatorio, pero es más cĂłmodo para la guĂa.There is an extra requirement (to have python2 installed). python2 has been retired on most systems, replaced with python3, but you are in luck. antiX 19.4 still brings python2 installed.
I have no idea about the first requirement (minimal knowledge of using the adapter). If you know how this adapter works, then that is good.
On the second requirement, you should be able to run the python commands and use the programs in windows, but I will try to help out in Linux.
If running on Virtualbox, you will need to connect the USB device (Adaptador de puerto serie TTL) through Virtualbox to work on the antiX Linux guest. Try first with a storage device to see how it works (and if it works) and then you can try passing through the other USB device. You need to select something similar to “Dispositivos > USB > (whatever name the “Adaptador de puerto serie TTL” has)” in the top menus inside virtualbox.
Then, starting the instructions:
1. Hacemos un backup de la flash entera para lo cual ejecutamos este script de phyton rt63365tool.py con el siguiente comando:
python2 rt63365tool.py --read=hg532sfull.bin --addr=0xB0000000 --size=0x800000 --block=0x10000
encendemos el router con el puerto serie conectado, el backup deberĂa comenzar inmediatamente. Puede tardar bastante en completarloUse Spacefm (can be launched from App Select). Navigate to the folder containing the rt63365tool.py file. Press the key F4 to launch a terminal that will already have the folder’s path ready. In terminal, run the command the same as the post mentioned, and see if it works.
Follow the steps in the guide. Note: You need to check the correct MAC address for the router (should be in the sticker on the back of the router).

General Live Boot Parameters for antiX.Thx!!! 4 all

Traceback (most recent call last):
File “rt63365tool.py, line 27, in <module>

ImportError: No module named serialAttachments:
No module named serial
Did you prepare a kernel module for your USB to serial adapter
https://github.com/matthiasbock/linux-i2c-ch341 may help.
As far as I am aware the module is not included in a standard kernel.Xecure
File “rt63365tool.py, line 27, in <module>
import serial
ImportError: No module named serialThis is one of the reasons I dislike python. You need all kind of libraries and it is never clear which until you run the script-
In this case, you need to install python-serial
sudo apt update && sudo apt install python-serial
Probably more error messages will come asking for specific modules. We will have to go one by one until we have them all.antiX Live system enthusiast.
General Live Boot Parameters for antiX.mi good is a “nightmare”… no internet in Antix (wifi usb TL-WN823N ok in W7 same PC)
search “python-serial” and many result
https://packages.debian.org/stretch/python-serial
https://pkgs.org/search/?q=python-serial
many options…
which one I choose?
How do I install it without internet?
thx again for you patience…Xecure
antiX should connect automatically to the internet inside the Virtual Machine, (this is usually the default configuration). I would:
1. Connect to the internet on your W7 machine.
2. Start the antiX Virtual Machine (it shoudl connect to the internet automatically)
3. Update the system (sudo apt update) and see if it properly connects to the the antiX and debian servers. If it doesn’t, check the Virtual machine connection configuration, so that it shares your internet connection in W7 with the virtual machine.
4. Install python-serial. If you cannot download it from inside the Virtual machine, download it on W7 from the Debian website (you can select the mirror you want if you cannot find an easier way to download it).
4. Try the script again.antiX Live system enthusiast.
General Live Boot Parameters for antiX.Finally make backup! many thx 4all especially “Xecure” for you patience.
Confirm Antix work perfect with CH341a in TTL mode, no need driver (automatic detection and function; amazing OS),
open bin and dates see like my firmware router (take 40 minutes, maybe much time, need test with putty-0.73.tar.gz 0.76 fail install ).
Fix connection internet (simple by ethernet, no wifi adapter)Attachments:
Hi! sorry again need your help…
How install putty (0.73 and 0.76 same error)?
How install offline python-serial_3.4-4_all.deb?
How show VM folder in SpaceFM?
