Firmware updates and down...dates

Am I missing something?

Seems to me it used to be that if you put a firmware update in the /tftpboot directory the phone would only update when the firmware was newer than what is already on the phone.

I use my 57i to connect to a bunch of different servers. For various reasons I do not have control of the what is in the /tftpboot. I just point my phone at the IP and use a reserved MAC.cfg file which I change to my MAC. The problem is if my phone has a newer firmware it ends up getting down-dated. Then when I log back into my server with the new firmware the firmware gets update. So my phone is often changing it's firmware which is not a desireable situation.

Is that supposed to happen? Is there a way to turn that ability off on the phone and lock it so that that config files and factory resets and "erase local config" don't remove that lock out?

Again, in my particular case I don't have control of what is in the /tftpboot of various IP's I point my phone to and it's a hassle to remember to rename the firmware file before I point my phone to an IP and then changing it back to the original name after I am finished.

I am doing this for legitimate testing btw.

Unfortunately it works as designed...

This is the expected behavior, if during the boot sequence the phone finds a different firmware than the one currently running, the phone will download it and reboot with this firmware.

This up/down grade mechanism was designed to allow to automatically downgrade to an "older" but certified firmware so the factory firmware does not need to be controled.

Sorry!
