Just want to report that the firmware update fails on P370 & 330 phones, using slot 1 (0.00) with customized firmware. I have to restart the phones and press the “Erneut” button (translates to “repeat”) 3 times…then it works.
The firmware I use is the original file from Sangoma…just the newest, which is usually not available in freePBX.
P370 4_23_2 is latest in EPM>Firmware Mgmt and I had the exact issue you describe updating via EPM Firmware Slot 1 v 1.76 on FreePBX 17 the other day and opened a ticket for it but no response on it…
It would fail multiple times then finally updated on the 3rd or 4th time…
