Hi @bornagainpenguin welcome to the /e/ forum.
So https://doc.e.foundation/devices/channel does say
Models Supported
XT1952-2
XT1952-3
Other models are not supported
It is not a good idea to flash a non supported model. The phone might even have a different device codename.
I found this, which talks about the difference between XT1952-4 and the others.
