In the last few days I have had several V2.1 update failures with different devices. Here, too, I had a bad feeling from the start, which was ultimately confirmed.
OTA updater only shows me version e-1.19.1-s-20240109372023-stable-emerald, but no version V.20, no V1.21.1, no V2.0, no V2.1.
The manual download of V2.1 is slow, even though I have a very fast internet connection.
The following manual update attempt fails with the error messages:
E:footer is wrong
. . .
E:Signatur verification faild
E:error: 21
For safety’s sake, the only thing I can do now is a complete reinstallation
