G30 - Is it possible to downgrade NBT2 EVO I-Step from 19-11 to 18-03

[Alec01]

Hello all,

My car is a G30 with production date 03/2018 and all units flashed with I-Step 18-03-541.
Recently, in order to remove my existing FSC codes, I had to virginized my NBT EVO.
I mistakenly performed  a clear SWT and a clear V850.
I think that clear SWT would have been sufficient to erase the FSC codes.

Anyhow, after clearing SWT and clearing V850, I had to flash my EVO with full Psdzdata & E-sys.
I only could find at that time a full Psdzdata 19-11.
Flashed operation terminated successufully, and now my EVO has I-step 19-11, while others remains with 18-03.

Everything is working fine, it's just that I don't like that an ECU has a different i-step than the others.
Also, now that my EVO was upgraded to 19-11, I can't anymore apply bin from usb. I need to do it thru ENET cable.

My question: is it possible (theorically) to downgrade my NBT EVO from 19-11 to 18.03 just by flashing with E-sys & full Psdzdata 18-03, without the need to clear V850 ?

No, full clear v850 but in ENET now is necessary and reflash.

Thanks @Scorpium59 ,

Is there a difference between full clear v850 and clear v850 ?
What I did before was just clear v850.

Is full clear v850 a deeper operation than clear v850?

[Scorpium59]

v850 full is full virginize so reflash necessary, v850 is just for swt/fsc. Not flash necessary.

@Scorpium59 Thanks, it is much clearer now to me.

Hi Dengus , Yes , just flashed and Now there is no text on idrive menu......every voice in menu is without text . Do you know what is wrong?? Thanks.

Hi nyuly,

To what I-Step did you flash the Evo ?
Can you run Ista-d, and check for HU faults ?
Can you post some pictures of the idrive menu without text ?
