Hello everyone,
After several hours of contemplation, googling and trail and error, experiments etc.,. I could finally get the .ipa file for the ACTON app to control the BLINK QU4TRO app.
I had to dig up my old iTunes backups, restore it on to the old iPhone using the iTunes app, connect the phone back again and use the iMazing tool to extract the .ipa file. You can also extract the .ipa file from iTunes but i haven't explored it. Here's the download link for the iMazing tools:
Windows version: https://imazing.com/download/windows
Mac version: https://imazing.com/download/macos
IMazing tool website: https://imazing.com/
Here's the YouTube video on my channel where I had shown how to extract the .ipa file from an IOS app that is installed on an iPhone. Process of installing is also shown in the video.
Here's the download link for the ACTON iOS app that has "Express connect" where you don't need to login to your ACTON account(which doesn't work anyways as ACTON servers are out of business) and yet you can control your Skateboards like BLINK S1, BLINK S2, BLINK QU4TRO etc.,
Please note that i have only tested this ACTON app with BLINK QU4TRO skateboard(world's first all wheel drive skate board). You may try with the BLINK skateboards that you have. I believe this express method doesn't connect to the BLINK LITE skateboard as it came up on the message.
I hope you find this blog post helpful! if yes, stay tuned by subscribing to my YouTube channel & the blog.
