Downgrading IP5000 from 3.3.2 to 3.2.x

[Anonymous]

I have pretty much the same behaviour as mentioned in => here <=

After downgrading from 4.0.x to 3.3.2 using the Downgrader 4.5.0B as per instructions on the EA64731 page 8, I tried to downgrade to a 3.2.7. I put the file on my server and always got the "incompatible image" message on screen.

 Tried also to downgrade the BootROM to 4.3.1 always got the "incompatible image" when the phone tries to load the 3.2.7 firmware. I used the http://voipt2.polycom.com/327 provisioning URL for the phone.

At the moment, I have the phone with BootROM 4.3.1.0440 and Firmware 3.3.2.0413.

Attached the boot.log at my provisioning server. 

What else should I be looking at?

Resolution: Please check => here <=

Based on your post and this post => here <= I tested this in my Lab and successfully downgraded a SoundStation Duo from UCS 4.0.3 Rev F to UCS 3.3.2 and then to SIP 3.2.7 and back up to UCS 4.1.0 Rev B without any issues.
