I don't think he's used the tool box yet. I suggest via swdl install a non modded version of the firmware then mod it with the toolbox. It's the modded version of 1447AIO that has failed. Probably someone has loaded up a poor version onto mibsolution.one where there was one that was fine before. That's what I suspect happened. Swdl on the mib2 high will allow you to re install firmware whilst the normal front screen won't.
I believe that map memory will be empty after 1447AIO so you have to load up the maps. N/A may just be saying the memory map
store is empty. That's where I load the maps in via swdl with the door open to keep the power on. It will moan fairly quickly if it's not taking the maps. That's worth checking if that hasn't been done. Assuming the maps are presented correctly. 7zip unzipped, no mac involved etc.
Failing that try an unmodded version of the firmware and the mib2 high Mr bonk toolkit. 1447 original. Unfortunately I think the mib2 high firmware experts have flown. I use swdl on the map updates since I like to see the maps being read in and progress. But that back end tool covers all aspects of how the mib2 high units assorted memory areas are accessed for updates. The hackers have bypassed the signature protection which is how 1447aio was constructed which is fine if they got it right. But will trip out if they haven't. Mr bonk toolkit is the alternative to mod the unit from an original firmware.
I do have a link when I used the tool which gets a bit heady.
Bones of using mib2 tool is here:
Working towards it... more of a cloudy day tomorrow so good for sitting in the car on it ;). It was Chillout's bragging on Drive and Jose on the Spanish board that alerted me to the 192 solution. Jose says MIB Tools wasn't used. Used a retro-fitter. Taking the DIY route but @jpmedia has offered...

Basically it's menu driven from the green menu. It's preset up with all the FeCs you need but you can add extra if required. It's one of these things you only use once and when it works. Job done.
