the charger works @5V, but I recall that a resistor is needed for the phone to detect the charger as an original charger
Hi,But well, that is not really true. There are 2 versions of the charger, the normal heavy one with transformer, and a light SMPS-one.

What voltage is written on the charger?

The first one delivers 5.94V without load, and the SMPS-version even 6.38V. The SMPS-one states "5.0V 350mA".
You need at least > 4.2V, since that's the voltage the battery is being charged to.
And of course the datasheet of the used charging regulator, Intersil ISL6292C states:
