But nothing else, though

//Edit: Just noticed that Bimmertech changes the '20...' in the MCU version to '10...' automatically. Weird.

Probably because of this:

nand erase.chip
nand bad

The original one has

setenv isp_block_size 0x${nand_erasesize}
nand erase 0 0x8a00000
nand bad

I still have access to Sunplus' original git (not Github, it's privately hosted) and can see the full commit history of the isp.c flash script.
I tried 5 different versions and none of them produce the same output as the original script. There are 2 that come really close and one of them turned my box into a blackscreen. So not that close apparently. ^^

ouch! That sucks.

That mcu date bug has always been there with bimmertech updates.

Previously when I soft bricked my unit with the later bimmertech updates, I could not get into the settings screen, the unit just would not respond.

Usual message is Invalid Update, so you have changed something

I hope the latter, if it was really bricked you overwritten your uboot partition and can only restore by directly writing the nand using hardware

What i have ready so far you can safely experiment and it will only corrupt but not brick the device. If it was bricked people should be very cautious with the experimental updates

Yeah soft brick, i could restore original andream version.

The freelance developer i spoke to said that the bimmertech version writes something to memory and this bit is checked when the devices boots up. If this bit is there it boots normally, if not you get invalid update.

"This latest BIN is justified from another binary pushed into your ARM nand memory. If I remove anything from this BIN will make the device bricked if flashed."

Or something like that at least....

Here's to hoping carlinkit can get the fix too

Did he mention the name of that bin that pushes the code to nand?

Okay, so I just installed the Andream box. Everything works good except the audio doesn't play on all of the speakers. I don't hear anything on the driver's side speakers. (Only passenger side speakers are working).
When I switch to BMW Idrive, then all of the speakers are working just fine.
Not sure what could be wrong...

I bet I know. Did you shove the un used aux cable somewhere that it could be grounding out? This happened to me and I pulled it out and re packed it. Fixed my issue.

That gives me an idea. So clearly my .bin was executed until some point where it didn't work anymore.
We could just add our own script at the beginning and terminate ('exit 0') before anything is written or destroyed.

That way we could dump the whole partitions from nand.

Getting all environment variables, 'nand dump' and even 'dd' is available, and then write that to the USB drive for further analysis.

If that works, then we should be able to "clone" another unit to our units.

Thus turning Andream units into Carlinkit or Bimmertech units and vice versa.

I actually thought that you were trying to insert a modded version of the Andream firmware with the corrected dpi value back into your Andream unit. Working with the Bimmertech ispbooot seems to add to the complexity.

Hi everyone, I've read the post and I can't see the solution to my problem. Firstly apologies for posting in this forum as I have a 2013 F06 not an F30.

I purchased the Andream mmi interface and fitted it, however the idrive doesn't control the unit. The car has a CIC stereo, however Andream advised to use the F30 loom that came with the unit. Everything else works, and I can toggle between the unit and the stereo using the 8 button, or use the phone to control CarPlay.

Andream suggested using the CIC wiring loom when I approached them with the problem with the idrive however the car doesn't like it when the idrive T wire is installed and it gives loads of errors in the car.

I hoping someone on here will have some ideas.

Thanks

I know this thread has gone down the software development rabbit hole but....

Does anyone know if these units have a GPS antenna in them? Does CarPlay use it or always the phone GPS? Sometimes Google maps gets a bit behind and the accuracy circle around the pointer grows.

It seems to get better if I move my phone, but that might just be coincidence.

If the unit has GPS in it then I might try and move it, it’s currently shoved in a slot behind the dash with quite a lot of metal around it.

it uses your phone's GPS.

Cheers, I’ll keep playing about with phone location. It lives in the arm rest, might have to see where else I can put it.

I was and I am. I just tried the Bimmertech update once I realized that I wiped the 'key' off my device to see if it would work.
It doesn't :/

i just brought a Andream CIC. i installed everything and it works great!

However i have no skip forward or back buttons on either the steering wheel or idrive. i press them and NOTHING happends

The other buttons like Call and Siri on the steering wheel work fine!

i have tried the following:
Checked all wiring
tried fitting the optional idrive loom that bypasses the idrive (No difference)
checked jumper switches.
the buttons work fine operating the orginal idrive system

its running the following:

SDK: 25.0.0.5.6.0.0.0
CUST: v2.1.0.5.1.gpe.c
MCU: 20.5.18.17

Please help

thank you friends!

Did you resolve problems with steering wheel buttons? I have same issue. Carplay CIC

Got it. At least now we know that it is possible to flash a modded bin.

Volume and back/forward on the steering wheel don't work on my AA CIC either.

How did you get the missing partitions to create the IPBOOOT.BIN?

I am trying to recreate the bin with the correct isp script.

I suppose you are talking about xboot and uboot?
Took them from the original .bin.

You have to look for start and end of each partition and extract them with dd.

//Edit: Only xboot.
Uboot2 comes from the extract function and is identical with uboot0 and uboot1, so just make copies.
xboot1 and xboot2 are also identical, so just extract that with dd from the original .bin and you should be fine.

Just installed my box, so far everything is working well. But I still have to test phone calls.

Does anybody know if the sequence of the apps in CarPlay can be changed?
