'Not enough space' error when flashing receiver with new firmware about expresslrs

[Zlyden3D]

I met the same issue.
The reason was the firmware version 1.0 on the receiver, and I couldn't flash firmware 3.0.1
After several tries with the same result (Not Enough Space) I flashed RX to ERLS 2.0 version, after that successfully flashed ERLS 3.0.1 version.

first of all: the easiest solution to the "not enough space" problem is to flash the receiver using betaflight passthrough instead of wifi.

second: the "wrong target" message is expected if you flash a receiver for the first time, as all the receivers use some other software from the factory as, at the point they were flashed, there was no official target for a specific receiver yet.
-> in that case you can just press the "flash anyway" button in the web ui.

third: yes, the 10.0.0.1 page also works with windows 11, but remember that you need to be connected to the wifi created by the receiver for that to work.
If you specified your home wifi name + password, it will connect to that, and the way to access the web UI in that case is to go to https://elrs_rx.local, or check the IP from your routers interface.

Even though my firmware claimed 2.0 I had first to update to 2.5.1 and then use the repartition hack and then was finally able to flash 3.0.1. Even then the uploader claimed failure but seems ok

I'm also having issues with the receiver setup. What a palava that so many of us have to go through.
A lot of people suggesting the 'partition' faff as a solution, but I believe that is only for TX updating issues,

You are correct. Repartitioner firmware is only for transmitters. I found out the hard way and bricked a receiver trying to do that but managed to unbrick it with a USB-TTL adapter. What seems to be the issue with your receiver?

I seem to have spontaneously successfully updated my receiver now.
I was making moves to update with an much older version of the firmware when I changed the settings that became available on the 10.0.0.1 screen. I then clicked the 'reboot' button near the bottom of that screen and now I seem to have a steady green light on the RX and the TX screen is saying full signal. Happy days. Palava though.
