After replacing the new memory IC, the memory contents are missing. The flashfile is not

Maybe this software update updates only a small part of your device
memory contents - I don't know.
In my repair I downloaded the offered file of the homepage
Seems to be a correct approach - maybe someone just made a dump of
complete memory contents and shared it. Have you flashed it already
and is it working?
Do you have a good buy recommendation for a good flash programmer that works well with
CH341A USB programmer - it works fine and also very cheap - about $2
or $3 with free shipping from China (e.g. AliExpress) or maybe
slightly more expensive to get it locally. Make sure to get a "green
PCB" version of it and also check that it outputs 3.3V instead of 5V
before using it: there was a small number of (mostly black PCB) CH341A
which gave 5V instead of 3.3V - although it's possible to fix them.
