Thanks. I have no idea what the ultra is.
I have LVGL working on these 
only have to replace the ESP32 WROOM with the new version that includes 2MB PSRAM 
Full YAML at this link:
LCD works with default display drivers now:
display:
- platform: ili9xxx
id: lcd_display
model: st7789v
spi_id: spihwd
#data_rate: 20MHz #oringal device uses 20mhz - 40 is default and works - does not work at 80mhz
#cs_pin: GPIO03 #CS pin is connected to gnd I believe
dc_pin: GPIO02
reset_pin: GPIO04
spi_mode: MODE3 #since no cs pin default is mode0
dimensions:
width: 240
height: 240
offset_height: 0
offset_width: 0
invert_colors: true

The ultra is also an esp8226 (esp-12f) , only the pro is an esp32 i think.

Hi, I tryed with esp-prog (uart side: gnd,tx,rx,vcc,io0,reset) but not worksā¦ What are your Arduino configuration board ? ( generic esp8266 or other like NodeXXX?) what are the flashing parameters configuration ? Why the Serial monitoring not works ?
The GeekMagic+esp-prog get power supply and run its weather firmware well, also works the boot and reset button on the esp-progā¦ I can swith the Geek to āupload modeā but the flashing procedure from the Arduino IDE not worksā¦ The logs shows āSerial COM11 Conectingā¦ā¦ā¦ā until the timeout !
Please help me!
Thanks.

A little off-topic but if anyone sees this post and has one of these that is asking for an activation code, PM me your MAC address and I should be able to generate one for you after I spent a good amount of time reverse engineering the process!

Can we admire your work at github or somewhere else in the interwebs?
Hello,
Can anybody send dump file of small-tv ultra or normal?
I cant scrollback firmware and I haveāt got backup
You can find them on their github.

How did you manage to upload a new firmware on this device? There is no /upload URL in this clone version, at least the one I got.
I had to go to settings and at the bottom there was a button that would allow me to upload new firmware. I use HomeAssistantās ESPHome interface and used the following code. Note that I am using an SmallTV Ultra, which seems to be based on the d1_mini platform.
Note2: I do not yet have the screen working. At all. If I can get this monkey business to do its job, I will update here. Until then I have a magic black screen that displaysā¦ NOTHING! ABSOLUTELY NOTHING! 
Note3- with my esp8266 I was able to get it working with @ra.javeenās code above. Now to play with getting what I want on the screen.

This is what got me going today! You are awesome!
Make sure the backlight is on.
Hey this helped me in reverse engineering it. I installed the WLED projectās latest binary and it works out of the box after changing the GPIO pin to 12 within the embedded web server.
Hi,
did you make a backup of your clone before you flashed it? Can you make it available to me? Unfortunately, I accidentally flashed a different firmware onto it and now nothing works. I would like to have the original firmware back on it.
Many thx!
Geekmagic now has a S3 version with USB to serial adapter on the USB C port so no need to ever open it up if you get it flashed bad.
It has the PSRAM so LVGL will have no issues. I wish price was a little lower though.

I emailed the developer and they confirmed:
Hi pro with esp32, ultra with esp8266
I was playing with the custom ESPhome firmware, but want to go back to the factory firmware. It keeps on asking for an activation code for my mac address. Does anyone know how to bypass this ?
TIA.
Could you please share more details as to how did you do it? I have the same clock but Iām struggling with it
Could you write documentation or share a video tutorial on how to install custom firmware on the SmallTV-Pro, just like youāre doing? Iāve never dealt with electronics, so I donāt understand how this works, and Iād like to know if itās possible to easily revert to the original firmware in case I mess up
Have you used esphome at all? I suggest getting familiar with it, and then reading this thread in full.
