SO SO LOST! I think i broke it

Hello all,
My name is Chris and I am very new to LoRa. I bought three devices off Amazon and some batteries. I was able to download the app on an Android device and on my iPhone. On the Android device, i connected one of the units and I get a popup that says, Firmware Update Required. So i click the UPDATE to 1.2.52 button and i get a message that says, FIRMWARE UPDATE ALREADY RUNNING.
The issue is, nothing ever changes. Its been in that state for about 3 days.
Since i was not able to update the Firmware over the air, i decided to try the Meshtastic Firmware Flash tool.
On one of the other units, I did my best to follow the steps on the Meshtasic site to Update the firmware. But I’m clearly an idiot and shouldn’t be allowed to touch anything electric. I followed the steps,

  1. i got a data cable, confirmed that i could see the device in the device manager "USB-Enhanced-Serial ch9102 (COM4)
  2. I chose to Use Meshtastic Flasher.
  3. I downloaded Python3 and run as administrator
  4. I install the, unzip and Run it
    Now, here is where i think i messed it up.
  5. after downloading the flasher, running as administrator i get this error.
    Step 1/4 esp32 full
    ESPTOOL Using command:–port COM4 erase_flash v3.3
    Serial port COM4
    Traceback (most recent call last):

    raise SerialException(“could not open port {!r}: {!r}”.format(self.portstr, ctypes.WinError()))
    could not open port ‘COM4’: PermissionError(13, ‘Access is denied.’, None, 5)

Any help would be great, on either issue, thanks everyone!!

I had a lot of issues when I first started. In regards to flashing the firmware, I had success using the manual update mode. You can verify each step as you go along. Just take it one step at a time and you’ll get there. Jim
