69xx Firmware Rollback on CME 9

Hi, I have hit a bug on 6941 phones on CME 9 load 9.2.1. Does anyone know how to rollback from 9.2.1 to 9.0.2 on CME?

I have tried the obivous, but 9.2.1 phones do not want to downgrade. 9.2.1 phones just boot up and register to CME.

In the settings, the phones show as

Active Load (9.2.1)

Inactive Load (9.0.2)

Here is my attempt to downgrade:

tftp-path flash:

tftp-server flash:BOOT69xx.0-0-0-14.zz.sgn

tftp-server flash:DSP69xx.0-0-0-3.zz.sgn

tftp-server flash:SCCP69xx.9-0-2-0.loads

tftp-server flash:SCCP69xx.9-0-2-0.zz.sgn

69xx Firmware Rollback on CME 9

Unlike other models, 69xx phones download firmware while being registered, then restart.

For this reason one  gets the impression they aren't doing it correctly.

- Firmware dowgraded automatically
