is it right ?

Solution​

Please download firmware [here](https://chiplesssolutions.com/download/WFC5710_FWG239TL_ZZ99Z9.zip)
Upload firmware to printer in normal mode - dont put printer in Program Update mode.
The uploading process will stuck at 70-80% - it is ok!
Printer will blink for about 5-15 minutes - then will power OFF.
Now power on the printer and run License utility and use your Activation Key you have used first time.
Please reply about results.

My friend
the printer restarts at 71%
and then the rest of the update from 71% to 100% is continuing and after that it says update is failed
Ok Now use License and Activation Key
