HP Tango stuck flashing yellow, cannot enter Wi-Fi setup mode (firmware lock)

[Swimmer18]

Moved to a new home and new WiFi network and HP Tango (circa 2020) cannot enter Wi-Fi setup mode.

I started an update via the HP app and everything was going well until the power hiccuped during setup. The test page failed to print and now I’m stuck with flashing yellow lights. The blue lights will not come on, even after multiple power resets.

This appears to be a firmware lock issue.

Requesting firmware recovery support!!

Hi @Swimmer18 

Welcome to the HP Support Community! We're here to help you get back up and running.

Not to worry, I'll do my best to reconnect the printer to your wireless network.

Let us try to restore the printer to the default network settings, and then use HP Smart to connect the printer to your Wi-Fi network.

Step 1:

Restore network default settings on the printer, to do that - Use the Wi-Fi button on the back of the printer to restore Wi-Fi setup mode.

On the back of the printer, press and hold the Wi-Fi button for five seconds.

Wait for the Status light to pulse blue.

Within two hours, return to the app or software to find and add your printer and complete the setup.

Step 2:

Uninstall and re-install the HP Smart app on your computer/mobile device.

Place the printer and the computer or mobile device near the Wi-Fi router.

Turn on Wi-Fi on your computer or mobile device and connect to your network. If the computer is connected to the network with an Ethernet cable, temporarily disconnect the cable and use the Wi-Fi connection during the setup.

Enable Bluetooth on the computer or mobile device so that HP Smart can detect the printer during the setup.

After installing HP Smart for iOS and Android, enable the mobile device location service and allow the app to use your location to detect the printer and offer solutions during setup.

Download the HP Smart app from 123.hp.com (Android, Apple iOS, iPadOS).

In HP Smart, click Add Printer or the plus sign to search for the printer, and then follow the instructions to complete the setup.

Let me know if this helps.

Hi Hawks_Eye,

As explained above I cannot get the printer to do anything besides a flashing yellow light. Pressing the WiFi button does not turn the light blue. Completing a hard reset does not turn the light blue.

The HP app recognizes my printer but cannot complete a test print. If I try to print from any other source it also fails.

All I have is blinking yellow lights which based on my research indicates that a firmware reset is required. Can you help with that?
