trying to force a firmware update on a mhi2 but it refuses to install all modules it only updates one module to look like firmware has installed correctly but it is not how can i force to do a full install tried swdl select all but does not switch to Y
That's going to be the boot loader only wanting to load up Skoda firmware ?. Wonder what happens if you open it up and do that pin short trick whether that's helpful or whether it reverts back to Skoda only. Don't take my word for it.
i actually got some seat firmware on it but it does not work properly, i think i stupidly jumped the wrong train also the unit is h42 0318 firmware
i managed to get in to the emergency flash tool but it will not accept any firmware on sd card or usb. complains about train info variant mismatch when trying from the update method. i wonder if the metainfo needs to be edited so it does a full install of the original firmware.
now the issue is i have given up on converting fully to seat and now trying to restore it back to skoda but as it has updated the variant info now it keeps asking for seat LOL. the mib2 std was so much easier
You could try the main mib2 firmware thread there were some experts about on there. Naughtly we could pick @East Yorkshire Retrofits brains, the reliable experts in retrofit. How to convert a Skoda mib2 high to a Seat mib2 high.
Little offtop but does anybody know how much amperage could usb deliver in leon 3?
Mine can't even maintain phone %; its slowly dropping; not sure exact number maybe ill check tomorrow. The one that support carplay have more output?
I'm looking for wireless AA box and I don't even know if usb will have enough power to run it..

I can answer a bit of that. The mib2 high units divide into two or whatever. Pre smartphones 1amp was all you needed. Those early version mib2 high set ups only put 1amp out. You know this since on an Android smartphone it will tell you it's not taking the full charge and that % battery falls.
2018 or so they changed things around and 2amps is output. This might be where I call @East Yorkshire Retrofits for the knowledge. It could be the usb socket unit that needs changing to get the higher amps. Either way this changed as VAG realised that earlier systems designed for non smartphone were no good enough for running the smartphone with AA or Carplay enabled.
I'm a Luddite about AA / Car Play I don't use it on my Ateca that puts out 1amp on that socket. I do have a 2amp 12 voltage adapter but that doesn't pipe the data just keeps the phone / tablet running and fully charged. The Arona with mib2 standard which we have also have (2019 model) does output 2amps so I plug it in up the front.
It's wireless charging that you may want. I don't think you'll get AAW as it's called (pretty definite think its missing the chipset on older models). That uses a dual band wifi 2.4/5 ghz. Your old unit won't support that. You need to stick to USB for the data link. Now whether you can change the USB socket to give you that at ~ 2amps. One for our retrofitter friends ditto a charging pad ?. You do see threads about on the board discussing wireless charging and solutions.
By wireless aa i have on mind boxes that plugs into usb (you connect to them wirelessly and it gives data thru usb to car)
If port is creating 5v it could be it But as it's connected to unit and getting 5v from it I'm not sure...
so if anyone could tell something on that subject I will be grateful.
With wireless aa box I'm going to use 12v adapter; later maybe fitting usb in center console(if it will be 2A)
I can't image good spot for wireless charger

There are some photographs on the board of people's solutions. I've seen them. Cables and boxes tucked in. It gets round that the car can't get 2amps out of the USB socket of those early units since they were not designed for power hungry smartphones that need 2amps. As said VAG fixed it but we're a bit late to the party.
I use to say in the early days of the Ateca it won't support a smartphone. People were not best pleased with my observations with their brand new car that they wanted to use AA / Car Play on. Even mib3s don't always get the level of charge into Smartphones... then we have the overheating problem with wireless charging. Newer cars have cooling under the phones
. All a bit Heathrobinson. I'm relaxed about it since I use the built in maps.

Wireless charging retrofit - done
After the passenger seat belt warning retrofit, my next project was installing the wireless charging using original parts. I bought a new deeper storage box with an opening for the charger, a rubber mat to fit into it, charger retainer bracket, charger itself and a connector, all from my local...

SW update for MIB2 infotainment system?
Yes the mib2 standard firmware isn't the bees knees it allows memory mismanagement we did get it once in the Arona. I pinned it down. That was due to embedded JPEGs in the music file being played in the unit. They are suppose to be circa 512x512. You would not expect a large jpeg breaking that...

cheers think i have mostly cracked it now, kept saying navigation database not available but there is a tool in toolbox to format the partition for the map dataThis thread

i should have used the AIO version to begin with
both the aio has its own but the separate one has more options to change variant etc
Must be new having its own. Busy programmers.
These things you only use once unless running a business.
First time i have played around with a harman unit, not sure really. Not sure if the conversion is correct or not as i can't connect to it with vcds CAN is no longer live but neverything else works apart from full link. I do wonder if there are more brand changes needed as the part number still a skoda one.
