This document describes the procedure for upgrading device firmware.
It explains how to check the device hardware and software versions, obtain the correct firmware file, and perform the upgrade via cloud platform or web interface.
Check Device Hardware Version
Before upgrading, confirm the device hardware version. Different versions require different firmware files.
Devices that have two hardware versions include:
E12
E16
R28
X915
C313
Devices that have three hardware versions include:
R20 Series
R27
E21
Take R20K as an example in this part.
Label
Check the hardware version on the device's back label.
"V2.0" on the back label represents hardware version 2, and "V3.0" represents hardware version 3.

Exception
R20A V3.0 represents hardware version 2.
R20A V5.0 represents hardware version 3.
Product Information
Check the device hardware on the device web interface.
Log in to the device web interface. The default username and password are admin.
Navigate to Status > Basic > Product Information interface.

Hardware Version:
20.X is hardware version 1.
220.X is hardware version 2.
320.X is hardware version 3.
Identify Device Firmware Version
When upgrading devices, confirm that the firmware version complies with the device model.
Take the R29 version, for example:
We can divide the firmware version number into four parts: A, B, C, and D.

A
A represents different models.
Door Phone:
Model | R29 | X915 | R20 | R20V3 | R20V5 | R25 Series | X912 | S539 | E12 | E13 | E16V2 | E16 |
|---|---|---|---|---|---|---|---|---|---|---|---|---|
Version Number | 29 | 915 | 20 | 220 | 320 | 25 | 912 | 539 | 12 | 13 | 216 | 116 |
Model | R27 | R28 | E18 | E21V2 | E20 | X916 | X910 | E11 | S532 | S535 |
|---|---|---|---|---|---|---|---|---|---|---|
Version Number | 27 | 28 | 18 | 221 | 120 | 916 | 2910 | 111 | 532 | 535 |
Indoor Monitor:
Model | C310 | C313 | C313V2 | C313V3 | C316 | C319 | S567 | S565 | S563 | S562 | IT88 | X933 | X937 | IT83 | C315 |
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
Version Number | 310 | 113 | 213 | 313 | 316 | 119 | 567 | 565 | 563 | 562 | 88 | 933 | 937 | 83 | 115 |
Access Control:
Model | A01/A02 | A03 | A05 | A08 | A092/A094 | A095 |
|---|---|---|---|---|---|---|
Version number | 101 | 103 | 105 | 108 | 92 | 95 |
B
B represents different OEMs.
30 means that the version with the Akuvox logo supports cloud, SDMC, and discovery mode at the same time.
31 means that the version without any logo supports cloud, SDMC, and discovery mode at the same time.
The other value is to distinguish custom-made devices.
C
C represents different branches. If the number is 10 or larger, the device is in the firmware version with high security mode. It is designed to enhance security. It employs encryption across various facets, including the communication process, door-opening commands, password storage methods, and more.
D
The higher the value is, the newer the version is when devices have the same model, OEM, and branch.
