Can not get versions or connect to device

[boriskogan81]

I just got a T-Beam and am trying to flash it.

When I try to get the software versions, I get this:

start of get_versions
tag:v2.0.23.7bb281d populate in dropdown?:True
tag:v2.0.22.fbfd0f1 populate in dropdown?:True
Unzipping files now...

    raise BadZipFile("File is not a zip file")

got versions

When I try to detect the device, I get:

start of detect

    return codecs.charmap_decode(input,self.errors,decoding_table)[0]
UnicodeDecodeError: 'charmap' codec can't decode byte 0x8f in position 265134: character maps to <undefined>
```

I've tried different cables, none works. 

The device powers on and I can connect to it via Bluetooth.

Please help.
