Geekmagic Ultra Bricked?

ESPHome

Hello,

I just bought a geekmagic ultra and may have already bricked it.
I followed this tutorial, but my guess is that the board may be slightly different.

I used this yaml code provided in the tutorial, just adjusted with my wifi secrets.
At first I could not create the bin file because Esphome said that the quotation marks are missing. (is this format correct?)

esphome:
  name: minitv
  friendly_name: GeekMagic Mini-TV

esp8266:
  board: d1_mini

wifi:
  ssid: "SSID"
  password: "Password"

#enable HA API
api:

ota:
  - platform: esphome

#enable logger
logger:

After flashing, the screen went off (expected) but the device never appeared on the network. It also doesn’t show in my router, lsusb, or ESPHome Web (no serial device detected).

How should I proceed?
Is there an easy way to revert to the original firmware?

If you don’t get an answer here…

You have d1_mini defined as board. It has 4mb flash. But in case yours has just 1mb, it would fail to run.

Thank you, will try

5

yeah could be, however at the moment I am just trying to get it running again. How can I get it into download mode to flash something else?

6

How you flashed it?

7

created the bin file with esphome and then flashed it via the webinterface that it comes with per default. (as shown in the tutorial) I don’t have that option anymore.

8

I don’t watch tutorials. So you flashed it using serial wiring?

9

are you joking :slight_smile: no like I said via the webinterface of the geekmagic ultra. now looking for a way to get it running again

10

No, I got confused with webinterface and earlier mentioned esphome web.
Nothing comes to my mind you could do over the air…

11

No worries!
no, but usually these boards have jumpers ors buttons to reset.

Hi @MrPopolino, I’m facing exactly the same issue. I’ve already bought a UART-Adapter aka “USB-TTL”, but I’m not quite sure how to cable it correctly and of course I don’t want to roast this thing at all :slight_smile:
Have you already made any progress to this?

Hi there sorry for the late reply.
I actually made the situation worse, I bought a Geekmagic Pro which has the esp32 in there because many reported that this allows for flashing via usb.
Had to order a USB TTL anyways because flashing via usb also did not work for the pro variant. So I still need to flash the ultra and the pro, let me know if you found a good guide as I also have no idea how to do it.
