Hello,
I want to update the firmware of handset w52h but if I download the firmware 26.30.0.50.rom of only 2MB from the official site when I try to upload the program to upgrade tells me "failed to open rom file" while if I use the rom 26.30.0.29.rom of 5MB i can upgrade the handset.
Where can I find the correct file of the last rom ?
Greetings Oberdan Albertoni.
Hi obeyealink,
It is indeed 2MB.
Could you download a new one?

I have tried it, and I succeed.
I upgrade from 26.30.0.40 to the new 26.30.0.50
These are my steps:
1.Open Update Tool,
2.Browse to load firmware,
3.Connect one side of USB cable to computer,
4.Press OK button of handset to activate it,
5.Connect other side of USB cable to handset,
6.Click upgrade.
I attached my updating picture.
Could you try again?
Thanks
