Huawei B593 firmware from 3 Denmark
Thursday, September 5. 2013
Sorin was kind enough to comment my article about Telia's firmware. He found a firmware from 3 Denmark for B593. Naturally I had to try that as soon as I could.
My previous articles about B593 are:
- Telia firmware not having SMS-functionality in it, Saunalahti firmware link
- DMZ-setting
- Dropping to 2G EDGE occasionally
The download link for 3's firmware is: http://www.3.dk/Privat/Kundeservice/Hjaelp-til-mobilt-bredbaand/Routere/Huawei-B593/#Firmware_opgradering
You will find a .zip-file, which will contain the firmware file with name hi3g_r+m+h+s.tar.bz2 in it. The file is dated 20th Nov 2012. After the firmware upgrade, a software version of V100R001C26SP054 will be installed:
The previously used Saunalahti firmware has software version of V100R001C260SP055, so the difference is C26 SP054 vs. C260 SP055. It is a known fact that telcos get a firmware modification kit from Huawei and can enable/disable features and add their own skins (see previous posts).
For all of us not fluent in Danish, there is a language selection in the login-screen. Beware: after the upgrade was done, I didn't have any connectivity. See:
The lack of connectivity was for the reason, that during update the APN-settings were set for 3 Denmark. Naturally they didn't work for me. This firmware has the VoIP-functionality enabled, thus, there is need for 2 separate APNs. Finnish telco's don't have the VoIP, so I cannot test that. But that does make the APN-setting -screen quirky. You cannot edit/delete an APN which is in use, either as data connection or VoIP-connection. There is no visual feedback about that, so I had to investigate the setting screen -logic for a while.
I did confirm that SMS-send/receive functionality is there and works. No issues on my tests. Also I confirmed my DMZ-forwarding, it still works as expected.
One fact that Sorin mentioned in his comment was, that he experienced lot of dropped connections with Saunalahti-firmware. His experience is that this firmware is more robust.
I'll update here if something surprising appears.
