Hardware Ps vita slim 2016 safe/recovery mode?

[Ninoh-FOX]

Does anyone know how to enter the recovery mode on a PS Vita slim 3.55 firmware?

no matter the fw, turn the vita off and you hold the power button until you see it - i think

OK, thanks, finally i can entry in recovery mode, first power off the ps vita, then push button power + button PS and when the led Green is light then push button R too.
