Endless Boot Cycle for Pineapple Tetra


Recommended Posts

I have followed the steps from https://docs.hak5.org/hc/en-us/articles/360010471774-Firmware-Recovery.

I am able to access to upload "tetra_factory.bin" .

After doing so, the pineapple gets into a loop of no LED light, followed by blinking blue light for approximately 1 minute, followed by approximately 20 seconds of a solid yellow light before starting over.

Could this be a power issue? I seem to have lost the original ac adapter over the years and have ordered a new one. So it is only powered via the micro USB cable connected via eth1 port.

Any suggestions appreciated.

What is in the other end of the Micro USB cable that powers your Tetra? A USB charger of some kind? If so, how many amps is that charger able to produce? The only guaranteed power method for the Tetra is using the original 12V DC adapter, so I would wait for the new one to arrive before proceeding searching for possible sources to the problem. You could of course make absolutely sure that you supply enough power via USB (I wouldn't go with USB ports from a PC though, even with a Y cable). It needs 24 watts for normal stable operation, i.e. 5 A at 5 volt. On the other hand, you seem to have been successful in supplying enough power when upgrading/recovering the firmware, so the problem might be something else than a power issue.

Well on the doc's page Power Considerations.

It says.


The 12V DC port accepts a standard IEC 60130-10:1971 type A connector with 5.5 mm OD, 2.1 mm ID (center positive)


I just got lucky one of my ac power adapters form an old modem combo unit had the right type.
