Ah, you're right. Try Chrome, it should download there, but didn't on Firefox for me.

I'll go back and post a new link.

Tried Chrome first. It does try to download the zip, but it hangs at zero bytes every time. Tried Firefox too, but would not even try to download at all.

Is it possible that this Disbox expects a Discord account link?

Shouldn't, it's hosted on my server, but those links should work. In any event, I've updated with a new download link with BuzzHeavier.

Unfortunately, I was not able to download from the new link either. Tried both Firefox and Chrome. Some access authorization issue.

Hey everyone, its been a while since I've updated my MMI, and it randomly disconnects from carplay after around 30 minutes (or at random times.)


My HW Version is: BMW_NBT2_1_G

What is the latest software/MCU for my device?

Not enough information. Need complete firmware.

Sorry, Here you go

SDK Version: 25.0.0.7.0.0.2.0
CUST Version: B2_V1.5.10
MCU Version: 21.6.7.116
HW Version: BMW_NBT2_1_G

Based on the first page, looks like an Andream B2-Version [1] [NBT]
Model: EW-BMCP-NBT04X

There is a Version 2 that has the same firmware format but with an "n" at the end: B2_V1.X.XX_n

Maybe someone with an Andream MMI can tell you if both the "n" and without the "n" are the same firmware.

The latest firmware I am aware of is: Andream B2 NBT lcbmw2e_n客户版EW_B2_1.6.16_n

It was posted for download more than once in the last few pages. The first page explains the process and risks of installing.

Ur trying to install a Mercedes screen on a BMW? you could try 1005 things i highly doubt it will ever work....I could be wrong but thats a new one...

[augustomoro]

Could someone help me identify the model of my interface.

I think it's a RoadTop (B-Version [NBT EVO ID5/ID6]) but I contacted them and they said it's not theirs.

I would like to update the firmware, if anyone could pass it on I would be eternally grateful

Is it possible to have MCU 23.8.7.121 for a Roadtop B2?
I've already upgraded to sw B2R176R4 but MCU only 23.1.12.117
Thanks for your support

The MCU update is via a separate firmware file. Road Top says not to change.

I proceeded to update the MCU to 20.10.22.16 from 20.8.19.23.

Now I cannot control BMW iDrive and neither the Andream MMI box. Just a blank screen.

HELP!!!

SDK Version 25.0.0.5.6.0.0.0
Cust Version B_V1.6.2
MCU Version 20.8.19.23
HW Version BMW_NBT

If after power cycling nothing happens, reinstall previous version of the MCU.

I would reach out to the seller first if you bought it directly from them.

You should still see your OEM drive By pressing the Menu or the Back iDrive controller button for two or three seconds (depending on your settings). Unless, there is a connection issue.

There’s also a force install option. Search the thread for the procedure.

Also, I believe you can create a file that you place in the USB root and boot into it. Something like #recovery110#. But search for it.


https://f30.bimmerpost.com/forums/sh...675929&page=78


Edit: copied the force install instructions from a seller. I assume this is for the CUST Ver update and not the MCU ver. update, but the steps may be the same for both:

Force upgrade steps:
1. Download the 3 files
2. Format the USB flash drive, copy the two files to the root directory of the USB flash drive (FAT32, less than 16GB)
3. Plug USB flash drive into USB port
4.After the car is powered on for 10S, then plug in the USB flash drive, long press Back button to enter the upgrade mode
5.After finishing the upgrade, hold for about 10 seconds before unplugging the U disk


For recovery, try this:

1. Create a 0KB file named: recovery110#
2. Place it in the root of the USB along with the correct MCU file
3. Boot into it as outlined in the forced update
