-12 Write failed on Shelly RGB2

[Diegocampy]

I'm back! After failing with a Shelly1 and then being able to flash other Shellys, I got stuck while flashing a shelly rgbw2

The operations carried out are:

1. flashed the minimal firmware tasmota ota mode http://ota.tasmota.com/tasmota/release/tasmota-minimal.bin
   Completed successfully

2. flashed 0x7000 firmware https://github.com/yaourdt/tasmota-to-mgos/raw/main/binaries/mgos512k-0x7.bin
   Completed successfully

3. connected to the mg wifi network - ????? and once connected:ù in prompt i type:

C:>curl -i -F filedata=@c:\SHRGBW2.zip http://10.42.42.44/update
HTTP/1.1 500 Internal Server Error
Server: Mongoose/6.18
Content-Type: text/plain
Connection: close

-12 Write failed

curl: (56) Recv failure: Connection was aborted

I am stuck here ... rgb2w.zip file is correct i am sure
If you have any suggestions for me, thank you

This is similar to #3 - none of the users there has provided me with logs, however, and I cannot reproduce the bug. If you can provide me with logs, that would be much appreciated. If not, please be patient, I'm trying to narrow down the issue

But imagine, don't worry, you're using your time to help people for free, I have nothing to blame you for. Unfortunately I'm not able to do any debugging, I don't know how to do it. I chose to try to convert the shelly with this guide precisely because it is done via OTA without having to connect anything, because I do not have the tools, and I would not be able

I'll just close this issue, as it the same as #3, we can continue discussion there
