Hp prime - bricked -stuck at the Hp logo

[Matheus Hermes]

Hello,

I need help, My hp prime is stuck at the Hp logo during the initialization process.

I tried to update the firmware to the last version using the Connectivity Kit, but didn't solve the problem, I used the symb key and the reset enter the recovery mode (V16).. and I did the downgrade of the firmware the versions 2015, 2016 and 2017, but not work too.

I also use the F,O,C keys to go to diagnostic mode and did the format of "C" unit , but didn't work too.

Besides that, I can only turn off the calculator when I remove the battery. Putting the battery
again the calculator automatic turn on, but stick at hp logo.
