the lifting of the front assembly from the silver bezel would be easier if you are heating the silver bezel with an hair dryer carefully.
because at older IPhones some mess will stuck between the bezel and the gasket AND if glas would be broken it will be a little bigger as the unbroken glas.
And heating the front assembly carefully makes it easier to peel of the glas from the assembly
