Another option is to spend the night reading SINET to find the wording you seek

It's not in there. The quotes I gave earlier are all there is.

I suspect this is one of those areas that cannot be clarified without a test case.

however, its likely that such a thing would never have got that far. as you are the customer.

In most instances, if a piece of kit stopped working, they would just give you a new one. and if it is their kit, then they would HAVE to.

Its probably not in any T&C's .. simply because they see no reason to put it in black and white.

Can I draw a parallel?

The question you are asking, and the points you make is response to all the replies you have received, are that nothing in any ISP T & Cs that you have seen cover this.

I have bought many cars in my life. I have never found any that provide either the detail of, or links to, the Vehicle Construction and Use Regulations to which I must adhere.

For example, Para 3 in:-

Schedule 4 - relating to dipped obligatory and optional front lamps. This says that only 1 pair of dipped beam lamps can be illuminated at any one time. It also says that the lamps are not to be lower than 500mm and not higher than 1200mm and not more than 400mm from the side of the vehicle.

1) If the extra lights come on with the main beam, then Schedule 5 applies and relates to obligatory main-beams and optional main-beams (i.e. front driving / fogs). Have to be no closer to the side of the vehicle than the outer edges of the illuminated areas of the obligatory dipped-beam headlamps (i.e. the pop ups). There is no requirement on separation of the additional lamps or the vertical position.

2) If they come on in conjunction with obligatory dipped headlights they have to also be dipped or extinguished.

3) If they are on without the headlights (dipped or main beam) then they are fog lights. They should only be used in "conditions of seriously reduced visibility IN PLACE OF the obligatory dipped-beam headlamps". So as long as the obligatory headlamps are lit (either main or dipped-beam) then there is no requirement for the horizontal position of the lamps only that they must be up to a maximum height of 1200mm.

In what you are given you will only find the position of the switch, and how to change the bulb.

It may only answer half the original Q, the hacking part, but not the replacing Q.

There is no rule/law/contract term to stop you hiring a car but using another, maybe also hired, car for the hire duration. Other than wasting money . You could hire a Rolls-Royce to attend your Palace Garden Party, but use your own Mini to pop down the shops to buy H.M. a prezzy the same day.

I think the underlying situation could be that he wants to hack the modem and is worried about the possible consequences.

He possibly hasn't picked up on the fact that the hacked version simply removes the locking down, and the place we get the hacked version also provides the unhacked. So reverting to the original is easy.

I think the question is this: Where does it say you can't use your own modem or load different firmware onto the OR modem?

I think the answer is: Nowhere.

To revert, I think all you have to do is to go back to factory settings by a hard reset.

Factory Settings are not the same as Factory Firmware! The former is data and the latter code, which nowadays are kept physically separated.

Well I remember the days when I modified machine code as data ; now frowned upon.

I know the original Q is:

People often comment that you can't touch the Openreach modem (to hack it or replace it), what's the official position on this does anyone know?

Either way will work.
