EHS36 Downgrade

[Waztrix]

I used to buy EHS36 that were Firmware version 1.16.0.0 and that was fine.

Then I started getting them with Firmware version 3.16.0.0 and I had to use a phone with the custom firmware to downgrade the EHS and get them to work properly. But when I did that everything was fine and working.

But just now I have received a completely new batch of EHS36 (30 of them) with 3.16.0.0 firmware, and I can't downgrade a single one of them. Every time I connect them to my "Firmware downgrade T26P Phone" it fails right away.

The hardware version is the same as the old ones (48.0.0.0) but I can still upgrade and downgrade any old EHS36 I have in stock - just not the new ones.

What can I do?

Hi,

Generally, the new EHS36 firmware has better compatibility. May I know what's the problem when you use new EHS36 firmware?

In what phone and headset model you encounter a problem?
If the problem is that call can't be picked up with headset can you please get a pcap trace, level 6 syslog and config.bin file? Our R&D will analyze it.

The post guide you have to get them:

Hey

We use Plantronics Savi 700 series (the W710, W720 and W740).

It happens on both Yealink T41P, Yealink T42G, Yealink T46G and Yealink T48G.

I have made a demonstration video on Youtube where I can show you how it works with a 1.16.0.0 EHS box and a 3.16.0.0
