T38G transfer failed

[Barnabas]

Thanks Jasit. I tried the link but it asked for credentials. I used my yea-link forum credentials but couldn't get in. The firmware seems to be for 3CX systems.

Instead I downloaded the UK version and tested it on a T38G in a lab. I upgraded it using our provisioning server and it worked perfectly fine. Yet when I tried updating our customer's phones remotely (via auto-provisioning) it didn't work. Both configuration files and the firmware were downloaded but the firmware didn't get updated. Only changes in the config files got applied.

Earlier we upgraded the firmware on one of the phones in our customer,s office by logging remotely through a computer and manually resetting to factory defaults and then manually choosing the new firmware which was downloaded on the same computer. But that didn't fix the problem.

last night i tried upgrading the same phone and another phone to the new UK version but both downloaded the firmware but non of them applied the new firmware. Here is the log which shows the successful download code 200 and the file size:
(IP address) - - [27/Feb/2014:21:59:40 -0800] "GET /T38/38.70.23.9.rom HTTP/1.1" 200 24790096 "-" "Yealink SIP-T38G 38.70.0.125 00:15:65:45:f9:e1".

And the worst thing that happens is that the phones get in a loop trying to download those 3 files repeatedly. I had to stop the provisioning server each time to break the loop.
I believe that those batch of 4 phones have serious problems which need to be sent back.
