normal tactics for Chinese any decent company would give you a loan tool in the meantime and arrange for pickup and repair...

                  First of all you should be shipping it to one of their authorized distributors in your region not China,Second it seems like your just missing their maxisys apk file so that you can update normally and why not send it to your e-mail on the tablet an executable file for that maxisys apk. third if their is a problem with other files on the tablet they should be able to correct those using team viewer or whatever remote control that works with maxisys and last of all I'm going to mention if you didn't buy maxisys from one of their authorized retailers their probably going to say unit trashed no warranty must purchase again with updates seen it before on forum. I'd get something from them stating your under warranty first before shipping. Your decision but why am I paying $100.00 for shipping if under warranty. What's the estimated turn around time stated especially if no loaner you need to be able to work in the meantime.

 it shouldnt really matter where you bought it they produced it and warranty is warranty..

 I think anyone that knows their way around a MaxiSys and how to use Team Viewer could access another Maxi Sys if they exchange the required information between one another. I think Eddie 65 even offered remote access service for a fee to diagnose car problems via team viewer if someone needed help. Can't see why a copied and pasted missing file  using team viewer might not be able to repair someone elses Tablet remotely

 do you know exactly which file is missing

 whats your e-mail..

                        That's why I mentioned about authorized seller's I'm going to guess they aren't honoring warranty cause Matco currently isn't one which gives them an out to deny service in their minds. They never answered another post which I hounded them about total care protection where hardware gets fixed depending on model for a fixed price and what happens if vendor chooses no longer to carry their products like your situation. As far as other members of the community helping by giving files nothing against them but like they already tried to wiggle out by saying you rooted tablet which was BS what then if it doesn't work out. Looking like Autel  won't support their hardware right now so where are we all going? Please reply back why they said don't ship it now to confirm their position whatever it is. Lost sales is where their heading it seems both with updates and buying new units.
