Hello there!

I have a S9+ Live Demo Unit and I want to remove the retail mode.

I made it with a Note 8 (N950X). It was easy, I installed Odin in my PC, and I installed the non-retail firmware.

Can I do the same in my S9+?

HELP PLEASE!

Starting with the S8/Note8, Samsung has removed the baseband chips (actually has never included it in the factory) so even if you manage to flash it with stock firmware, it will never pick up a signal no matter what you do. And no, you can't solder in the baseband chips, they are custom chips and extremely difficult to solder being fine pitched surface mounts.
You best option is to try to flash it with the latest stock firmware, disable the MDM security, and use it on WiFi only.
By the way, the N950"X" version is not even a US Qualcomm model, but an international Exynos based main board, so don't waste your time trying to flash the "U/U1" firmware. Try the international "F" version, but most likely it will only accept the specially modified "X" firmware.

You are wrong. I made It by myself.
I'm Spanish, so I have the Exynos model.
I installed the F Firmware And everything OK.

In the US we have the "X" model which I have physically opened up and the baseband chips are missing, while on other models they removed the sim card contacts completely and it's not resolderable. Look they are not dummies, they know exactly what they're doing.
You can clearly see the empty solder pads which normally are populated with chips. So please don't jump to conclusions so fast before checking the facts.

Thanks for your experience. I am stuck with same case. I have been trying to install the F version on the US Galaxy S9+. The greater problem my LDU has is that the date is incorrect and no settings is enabled to allow me make any adjustment. Every necessary settings greyed out. Odin flash attempts all failed and Samsung Kies will always say I should enable USB debugging to even see and recognize my device but that option in developers mode is all greyed out and not allowing enabling. Same thing with factory reset not allowed. What can I do to at least use the Wifi because now it cannot connect due to incorrect date setting still whowing March 2018?

If you want to factory reset but cannot enter recovery for whatever reason, set up security to wipe your device if the wrong code has been entered 10 times, then enter the wrong code 10 times

My problem is that those security settings are not enabled for change as they are greyed out. So I wouldn't even know where to go to set up security to wipe off device. Moreover, I don't usually log on to the phone with code. Are you suggesting I set up code to open the phone screen so that I can enter wrong one or which other code are you referring to? Thank you Sir.
