Hi
facing some issues to firmwareupgrade/downgrade of several 7921G Phones via USB.
I can upgrade downgrade phone to different software versions (1.3.4, 1.3.4Sr1, 1.4.1). I have downloaded the 1.3.3.tar several times same error.
Only up/downgrade to 1.3.3 fails "error in browser" "error in uploaded image"!!
Does anybody know why und how to solve this problem?
regards Chris

7921 phones with Hardware Revision of 3.6 do not support firmware 1.3.3 and earlier.
You see the Hardware Revision of a 7921 through the usb cable upgrade process.
The big issue here is that firmwares from 1.3.4 to 1.4.1 (currently latest version) just suck.

What kind of phone load is that? What version? Would you be so kind as to share it with the community once you get it?
Thanks.

version is 1.4.1.0.5 wich is TAC release.
I don't know if i have the permission to share this Image!
After some test's i will ask the TAC engineer.

Well, it would be very appreciated if you could ask TAC permission after your tests, since the current firmware is really really bad.
Thanks in advance.

You will need to open a TAC case to get any ES load for the 792x phones.
