Jason,<div><br></div><div>Thank you for this, the phone in question is indeed running the F.2 image and I was trying to go down to 1.4.1, it seems the newer firmware causes phone calls to cut out/have gaps so I wanted to stay with the safe release. </div>

<p>The F.2 image is equivalent to 1.4.3SR1.2 and any new hw revs that require this load or later can not be downgraded.<u></u><u></u></p><p>This is outlined in the 1.4(3)SR1 release notes.<u></u><u></u></p><p><a href="http://www.cisco.com/en/US/docs/voice_ip_comm/cuipph/7925g_7925gEX_7926/firmware/1_4_3SR1/P256_BK_WC0078A9_00_wireless-phone-release-notes-1_4_3sr1.html#P256_TP_W908AC8A_00" target="_blank">http://www.cisco.com/en/US/docs/voice_ip_comm/cuipph/7925g_7925gEX_7926/firmware/1_4_3SR1/P256_BK_WC0078A9_00_wireless-phone-release-notes-1_4_3sr1.html#P256_TP_W908AC8A_00</a><u></u><u></u></p>
<p style="min-height:8pt"> <u></u><u></u></p><p>Per the screenshot above, you can see this 7925 is hw rev 3.0, which is the latest rev that requires 1.4.3SR1.2 or later.<u></u><u></u></p><p style="min-height:8pt"> <u></u><u></u></p>
<p>New 792x phones pre-loaded wtih the F.2 mfg image will require 1.4.3SR1.2 or later as that release contains an updated LCM driver.<u></u><u></u></p><p>There are restrictions in place to prevent downgrading F.2 or 1.4.3SR1.2 to earlier builds; e.g. 1.4(2).<u></u><u></u></p>
<p>If you attempt to perform a phone recovery via the bootrom to load a non-supported firmware, then the phone may not boot properly.<u></u><u></u></p><p>So you would need to just perform this process again to recover the firmware by uploading 1.4.3SR1.2 using the TAR file.<u></u><u></u></p>
<p style="min-height:8pt"> <u></u><u></u></p><p>So in summary, the recovery process should only be used to recover a phone with a corrupt image and should NOT be used to force a downgrade.<u></u><u></u></p><p class="MsoNormal">
