Fanvil X7A delivered with fw 2.6.0.1153. Downgrade to 613 leads to

[chrisbeam]

We recently got a new batch of Fanvil X7A delivered with Firmware Version 2.6.0.1153. 3CX displayed these phones as PNP Phone.

One couldn't properly asign the phones to an extention. It was not possible to upgrade/downgrade firmware via 3CX. So we had to try fix the FW conflict via uploading firmware from the phone webpage.

A downgrade to 2.6.0.613 or 2.6.0.1282 leads to the phones being unreachable via the phone page of the device. The Android software displays that the phone gets an IP address, but when you click on the Fanvil own part of the system, it displays 0.0.0.0.

A reset and clearing of all user/device settings with the android surface, is impossible. You can not even get it to reboot. You have to remove power supply to reboot.

We are now trying to hard reset the phone.

Hi Regarding resetting the device, we have a special method. After powering on the device, please try using four fingers to tap multiple times on the four corners of the screen. Please try this method to see if it can reset the device.

Thank you very much. That did the trick. Interesting enough, after resetting, the phone X7A displayed the desired firmware version 2.6.0.613. It looks like the phone tends to get stuck when we have to downgrade the firmware when delivered phones have afirmware abouve 1xxx
