More information is required to this request, as you failed to mention the "Brand" or "Model" of the device you are referring to and which is dedicated to a certain range, however please note the following. - AN IMPORTANT POINT CONCERNING THE MODIFICATION - The instructions given are really aimed at technically minded people of a "practical" nature who are acquaint at working on smaller electro-mechanical devices of a precision nature, or who have a flair for this sort of thing, and so in the interests of not making the situation any worse I would strongly advise anyone who does not really come into that category "NOT" to attempt this work, as it involves separating the case and the unscrewing the main circuit board to gain access to the board below it, this requiring the disconnection of ribbon cables etc, it is also necessary to carry out the precision soldering of two "very" narrowly spaced PCB pins, so the possession of a fine tipped (pencil pointed) soldering iron is also absolutely essential! So taking the above into consideration the qualification mentioned is really a MUST!! It should be emphasised that there are NO shortcuts into getting over this problem other than what's been aforementioned, and even if the memory reset does affect a cure it can only be adopted as a stop gap measure as the CPU could lock up again at some point in time, and unfortunately in many instances does!!
