actually, the conclusion is "From 20 June 2025, manufacturers, importers or authorized representatives shall ensure that the process for replacement of parts referred to in point 1(c), meets the following criteria: the process for replacement shall be able to be carried out by a layman."
and the 1(c) is
"From 20 June 2025 or from one month after the date of placement on the market, whichever is later:
(i) manufacturers, importers or authorised representatives shall make available to professional repairers and end-users at least the following spare parts, including required fasteners, if not reusable, until at least 7 years after the date of end of placement on the market:
(a) battery or batteries;
(b) back cover or back cover assembly, if to be fully removed for replacement of the battery;
(c) protective foil for foldable displays;
(d) display assembly;
(e) charger, unless the device complies with Article 3(4) of Directive 2014/53/EU;
(f) SIM tray and memory card tray, if there is an external slot for a SIM tray or memory card tray."
i think, that scope of repair is enough for end user. cause the mainboard repair requires more tools like hot air and soldering station.
maintenance information also at least include electronic board diagrams. and i think it good enough to help diagnose and repair process. even though it need registration which i think will be hard and manufacturers may charge reasonable and proportionate fees.
but i think at least manufacturer forced to make diagram exist. it better than nothing.
also it stated in the regulations that
In order to ensure that devices are able to be effectively repaired, the price of spare parts should be reasonable and should not discourage repair.
