JJOS2 UPDATE: PRESS ERASE BUTTON FIRST?

hi folks,

searched the forum yet, but haven´t found any answer.

running JJOS1 5.56 on my 2500 and would like to check out JJOS2.

read many times how to upgrade, but on the JJ OS website, i found this note:


When you change OS, please switch on a power supply, pressing the ERASE button first.
Please press the ERASE button until a main screen is displayed.
If this operation is not performed, MPC may freeze or it may crash.


further on in the explananation from JJ it is said that when changing from JJ OS2 to JJOS1 a "STOP" key should be press while powering up


i´m confused what when and why to do...


please help


thanks to everybody for your help

Do both just to be shure

Holding the erase button during power up after any time you change OS's is a good practice, otherwise you may get odd and inconsistent behavior.
