RE: Yealink T28P Firmware Upgrade Fails
Similar problem here. Also from the Netherlands.
I just have a nasty feeling about this now.
Happened with 2 clients

We have been given a batch of 12 Tiptel VP28 (KPN)...of which 3 pieces were defective out of the box. And 3 other showed defects within 48 hours. I found out the older hardware versions are just faulty.
50% failure rate is a bit high. I've convinced them to buy Cisco.

Another client had something similar. They had some Tiptels of which 4 out of 6 broke down within a week. So they opted to buy something else.
This customer was aware Tiptel and Yealink are similare hardware.

As the customer insisted on Yealink I let them buy a pair.
They got the T28P...Did a straight from the box firmware upgrade and..nothin'

It stinks the advice is to contact the dealer for firmware (although forum says to contact Tiptell...who in turn says to contact the dealer.)

I'm tempted to tell them I refuse to service any Tiptel, Yealink, Innovaphone. This is not the service level I expect from a German Company.


So what happened:

After an upgrade...no change in firmware.
I tried different versions of firmware even downgrading.
Even tried a stepwise upgrade (like mandatory with Cisco phones) but nothin' succeeded in reality.

Firmware Version 2.70.188.13
Hardware Version 1.0.0.53

During upgrade is mentions:
__Firmware updating ...
__Please do not power off!
__The operation is done!


Well no change after the upgrade at all...

Edit:
Well found this post, gonna give it a shot....Dodgy...and that also didn't work out...
