wifi and bluetooth problem

asus36

\n\nhi,
since yesterday, I have a problem with wifi and bluetooth that I can not activate
Also I have a problem with recovery where when I try to install the stock rom I get this error:
"installing ..............
checking for file MD5 ...
Skipping MD5 check: no MD5 files found
check_cu () falied, ......... did not match cu modified system: Unknown
error executing  updater binary in zip ............
error flashing zip ...............

these days I have tried to make porting from miui xiaomi mi4i and I think that the kernel has been damaged after the last test.

any idea on how to solve?
EDIT:
fortunately I restored a backup but I still can not turn on WiFi and bluetooth

Maybe try the eMax Mini Unbrick kit ?

Save your QCN (just in case of)
Send the new image

=> You are now with factory settings

thanks for the advice but I was able to reset the phone with the Flashtool posted in this forum
