You were able to upgrade to firmware 24.5 on your Spark EV? Is the firmware file the same as the one the Russians used for the Cruze? Any gotchas?
Same here. I think if we flash the new firmware we will lose the energy screen but the rest should work fine to chicken to try though until I get some confirmation.
I'd rather not give up the energy screen(s) if it means we lose the ability to change the amperage setting for 120V charging.
Having said that, I've been perusing the sites for firmware upgrade/hacking. Started a dialogue with Youtube user wbif88. He seems to be the most prolific poster of guides to hacking MyLink/MirrorLink (https://www.youtube.com/channel/UCbnTt4 ... nDKZ8SrFpQ
He's not seen firmware 15.x or 16.x. His list of firmwares goes from 10.x to 13.x to 20.x to 23.x to 24.x.
So, we'll see what comes of this. I've asked him about upgrading and the possibility of downgrading if 24.x doesn't work. He says to downgrade if 24.x doesn't work, but nobody has the 15.x or 16.x firmwares available...yet. (My 2014 Spark EV has 15.41-95281509).
There's quite a bit of talk about reversing camera and video-in-motion; interesting stuff, for sure. I can't play with a firmware upgrade until I source a camera (any suggestions are most welcome!).
It seems that the camera functions are encased within /Storage card/system/MgrMcm.exe; this file should be copied to a flash drive for backup and replaced with one that includes camera functionality.
I've entered "Developer Mode" according to the instructions. No big deal. You can't hurt anything by doing that. Just don't change anything. You can surf to your heart's content. It's "only Windows CE". <cough><gag>. I'm in the process of backing up everything from the head unit to a flash drive.
After that, I'll see if replacing MgrMcm.exe (and perhaps ClientAppInfo.bin (located in storagecard/system and storagecard2/system/) do no harm.
ClientAppInfo.bin is where the information for BringGo, Pandora, TuneIn and Stitcher are located. I believe this is also where MirrorLink info is stored; it appears that MirrorLink is included with firmwares 23.x onward. Something to think about...
I use BringGo; it works, imperfectly, but it works (paired with a Nexus 5). I've used Stitcher whilst sitting and charging at L2 charging station with free WiFi. It works. I've not tried Pandora or TuneIn, although I have accounts for them. I tend not to use my cell minutes for music streaming.
