Firmware install too fast

[spentamanyu]

Hi!

I am new here and I am having some troubles.
my board is the KC868-A6-v1.3
the firmware I am trying to install is the KCS_KC868_A6_V2.2.8.bin
the flash tool version i s the 3.9.2

My problem is that it flashes it way too fast. In the youtube videos you can clearly see a progress bar and that it takes some time to upload the firmware.
Mine does not, it just go from START>SYNC>DOWNLOAD>FINISH  in two seconds. Meanwhile the background shell shows this


is stub and send flash finish
.
Uploading stub...
Running stub...
Stub running...
FLASH_CRYPT_CNT 0
ABS_DONE_0 False

is stub and send flash finish
  but no progressbar or uploaded byte info. How can I be sure that the version has been uploaded properly? Might it be the reason why I don't find any AP after reseting it?

thanks!

No luck with any firmware.
I started using the ESP_EASY_FLASHER and found this log

i think you can try to use another computer.
re download the ESP32 download tool: https://www.kincony.com/wp-content/uploa..._3.9.2.zip

I found it. I am very sorry for wasting your time. The problem is embarrasing, I forgot to click the checkbox of the bin file.
As soon as I selected, that row went green and it flashed properly.
Again, sorry for bothering you, and thanks a lot.

ok, good.
