My Tangara appears to have bricked :( - TheCraiggers - 2025-09-10

So I was hoping to upgrade to the latest firmware today. Here's a somewhat rough sequence of events:

1. Plugged device in, opened Tangara Companion app. The app couldn't find the device.
2. After trying a few things, I eventually reboot my computer. This seems to fix the connectivity issue, and the App can see the device now.
3. I click firmware update, select the new shiny 1.4.1 firmware file, and push the go button.
4. Update immediately fails with a connection error at 0% (I wish I had thought to grab a screenshot)
5. I try again, same outcome.
6. I click on the device tab and the companion app says it can't find the device.

At this point I begin the holy ritual of unplugging it, trying different USB ports, etc. I look up the hard reset sequence and try that many times. So far, nothing has worked. Screen is black, no vibration or the like when I turn it on.

That said, my computer does see something when I plug it in.

Code:
[ 6694.486628] usb 3-1: new full-speed USB device number 9 using xhci_hcd

[ 6694.605648] usb 3-1: device descriptor read/64, error -71

[ 6695.989690] sd 2:0:0:0: [sda] Attached SCSI removable disk

The companion app sees something, tries to communicate with it and then fails:

Code:
error opening tangara: Connection(Sync(Io(Custom { kind: TimedOut, error: "Operation timed out" })))

At this point, I'm wondering what I can do. Any esoteric tricks to try? I'm thinking of trying some of the more advanced flashing techniques listed on the website, but wanted to confer here before I muddied the water any more.

I bricked my Tangara going to 1.4.0. I think due to a cable related connection error. I was getting similar results to you and got it back following the guide for manual flashing.

Thanks, good to know I'm not alone and (probably) not about to make this worse!

Yay, all fixed. Thanks Habmala!
