Thank you for your advice. So if I understand your message correctly, I should best downgrade to 2.53enable develeper, enter testmode , swdl , select all. unselect DUE405 or DUE406,DUE409,DUE410, DUW013, DUW014 is 8 inch.
all must selected on Y except monitor. start update using MST2_EU_SE_ZR_P0253T
My MIB2 is 6.5 inch, so which ones do I need to unselect?
