MHI2 US 2 EU Update to lower software

[Libargo]

Hi! I need install EU software MHI2_ER_AU43x_P5098_MU1339, now is installed MHI2 US AU43x P5124, in green menu I activated user defined and region ignoe but in red menu still not active user defined. When I try standart mode I see that not all software will be update so how it will work after standart update? In the folder IOC are different files. May be there is another method to upate this software?

I tried before eeprom correct and after is the same - user defined mode not active. And I cant change one bite in eep.

Please need any help!!!

Downgrade is not so easy. You have to reflash manually RCC, IOC, MMX. Then run FULL update process. RCC can be done in emergency, IOC and MMX only manual.

How about emergency update from green menu? It should delete all flash and write it back from sd?

Some FW version doesn’t allow to make User Defined mode when flashing device.
