So, got cracking on with this G11 to G13 conversion.
Usual disclaimers: Please don't try this at home unless you're sure it'll be ok, I can't be held responsible for others!
So the first order of business was to take the 128GB SD Card I used for the previous update and gave it a quick format with Rufus, followed by copying over the G13 AIO firmware.
The contents contains instructions to perform the G11 to G13 conversion, so I followed them to the letter, changing properties on the metainfo2 file from:
To:
So a couple of flags to disable version checking and what "train" the update supports. I note that for the Skoda ones, it has a wildcard MHI_ER_SKG11_* so I suppose anyone with a bit more bravery could try it with any version of the G11 "train", but I wouldn't recommend that at all.
It also mentions in the website guide to rename the _Swdlautorun.txt file to remove the underscore prefix, which should then mean the card insertion is enough to kick start the update process.
So a few deep breaths...
But before that, made sure the battery charger is in place and keeping the battery topped up (it was left on overnight, so I think it'll be good).
Then some preparatory stuff.
Firstly, for this particular display, remove the trim around the display:
I used fingers at first to get some purchase then a standard trim removal tool to slide around the rest, and it pops out:
This reveals the slots for the insertion of the keys, so inserting the keys and with a bit of wiggling in my case, it should come free:
I left the display hanging slightly, so that once the update reboots and then expects the newer screen, I can then swap them over with just the two cables to change.
I few more deep breaths, and the SD card is now inserted into the head unit, with the display immediately detecting the card and showing the same messages as yesterday with the normal firmware update procedure:
These photos are almost the same as yesterday:
However, once it rebooted, the display remained black, but I could hear what presumably was the head unit fan (or at least some fan around the glovebox), so decided this was the moment that the head unit was now only going to work with the new display.
So pull the old display out enough to get my fingers onto the connectors, and luckily they all came out without much drama. Inserting the connectors into the new display then revealed:
Did a little first bump as the display is on and working!
I then got a warning message, one which the guide explicitly mentions:
It stresses to just press skip, as cancelling could be a disaster! So once skipped, it pretty much finished:
Checking the version by holding down the home button:
Success!
It took pretty much the same time as yesterdays firmware update, so around 35-40 minutes.
Next step is to reinstall the maps, which I've decided to do with the SD card reformatted again, but this time to exFAT just to feed my curiosity.
The install process is then the same as a standard firmware update, going via the service menu to search for updates:
The install for this took longer primarily because of the huge size of the maps I presume. Took the opportunity to give the car a quick once over with a vacuum. It will need a few more goes by the looks of it, but it is what it is.
After a few more restarts:
Maps are on.
I also added POIs via another update, this time, via a microSD card with an adapter. This also worked, so the general advice of using a good normal sized SD card is more a wise precaution, if for whatever reason you don't want to spend the £8 or so for one.
