Allview V-Bass Firmware Update

Introduction

The Allview V-Bass speaker is a Bluetooth and WiFi compatible speaker (LinkPlay Module A31) with a power of 3 W Compatible with the Amazon Alexa service.

Since the commercial release of this speaker, Allview has not updated the firmware and application allowing the control of this speaker; thus making it inoperative for the use of Alexa online services.

The original firmware also contains a large number of security vulnerabilities (CVE-2019-15310) making their use vulnerable to attacks.

This tutorial will explain how to update the original firmware with an alternative firmware.

Disassembly of the device is not required.

What you need

Step 1 Connection to the speaker

Allview V-Bass Firmware Update, Connection to the speaker: step 1, image 1 of 1

If your speaker is already connected to your Wifi network, from a web browser connect to it: http://<adresseip>/
If your speaker is not yet connected to your wifi network, look for the speaker's access point (by default V-Bass_xxxx) and connect to it. Once connected, the web interface will be http://10.10.10.254/

Step 2 Download a compatible firmware

This speaker is powered by an A31 rev 04 module built by Linkplay. The UUID number of the speaker is FF310022. Another product powered by Linkplay to the same UUID, so it is at all points identical at the material level. This is the Meet Riff marketed by theFABRIQ (ref: WB 22)
The firmware was pulbiased on 04/12/2018 and is powered by version WiiMu.4.0.6404 instead of version 3.6.4324 published on 24/04/2017
Downloaded the firmware from the linkplay update site: Fimware

Step 4 Download a compatible application

Many applications are compatible with this speaker (more than 200) (because all based on linkplay)
I have referenced the one that should work on Android here.
The most up-to-date (when writing this article) is Audio Pro Contol available for Android and Iphone

Step 5 (Optional) Updated with Curl or the official tool

Once the update is done, the new firmware versions no longer have a WEB interface to perform a new update.
To make a new update, you must therefore go through the command line:
Retrieve the curl tool
Started a command prompt and then type the following command after having customised it (IP of the speaker, and file)
Curl -H 'Upgrade-Insecure-Requests: 0' -F 'filename=@file_du_firmware' http://<IP_DE_ENCEINTE>/cgi-bin/upload.cgi
You can also use the update tool distributed by Linkplay downloadable here (a tutorial is available in the archive file)
