HP Prime Firmware Update Problem

[TaeML]

I just performed all the possible solutions of fixing the problem:

1. On-Symb ==> Didn't solve the problem
2. Holding C-F-O and pressing ON button to refresh the firmware ==> Didn't solve the problem
3. Holding C-F-O and pressing ON button to format Disk C ==> Didn't solve the problem
4. Re-doing the flash process by holding the SYMB and pressing the reset button and connecting it to the computer to update the firmware using connectivity kit ==> Didn't solve the problem

Note for #4: Connectivity asked me to update after connecting the calculator with the recovery mode screen and the update window flashed 3 times and updated successfully.

Not sure why this is happening, but is there any other solutions that I can perform to fix this issue?

-Thank You
