N2 - Resistance versus temperature dependence in several sets of 2DTI samples fabricated on the basis of 8.3 nm HgTe quantum well using the same technological procedure has been investigated both in the presence of weak perpendicular magnetic field and at B=0. The obtained results do not confirm the universality of the behavior previously interpreted as the Anderson localization of the edge states of a 2DTI induced by a weak magnetic field (Piatrusha et al., 2019). Some samples are found to be insensitive to weak magnetic field and show clear signs of localization even at B=0. In diffusive mode and at B=0 the variation of the edge states resistance with temperature depends on the initial resistance level and can be both weak and exponentially large.
