I am new to the android programming world. I own an iQR70 device from MLS that is using -if I read well- the kiosk mode for its own application called MAIC (something like Amazon's Alexa a virtual assistant).

The real pain with this device is that the application is buggy does not get any updates and overall does not work properly.

So, my questions are, a) is there any way to disable the kiosk mode and work with it as a normal tablet? or desperately b) Can I install a compatible firmware? I don't care for the data inside.

**EDT : I tried to install a stock firmware "Version: MLS iQR70 – 7.0_MT8167_V1.0_20180111-B1" from https://firmware247.com/mls-iqr70-firmware/ using "Format all + Download" using MediaTek SP Flash Tool v5.2052.00 and now does not powerup. It doesn't even connect anymore with the SP Flash Tool. Is the device completely dead? Is there any way to revive it? I have two of them, can I download/upload the firmware from the good one to the bad one?

  • unfortunately "format all + download" will erase secro persist and other important partitions. but the issue is probably flashed wrong preloader which bricked it completely (not sure about, preloader is for iqr-70 and should still work). disconnect battery and try again

  • @alecxs thank you, I will give it a try. Can you tell me please if I can quit/exit from the "kiosk mode" of the virtual assistant that comes with this tablet? In the other one I own, I have no access to anything but the virtual assistant. I can get in ADB mode but the device is not listed and I can use the fast mode which OEM unlock is not allowed. What are my options?

  • @alecxs This device does not have a battery at all but I formated also the preloader.... which as far as I understand is the connection with the hardware itself. The problem where is that SP Flash tool can not see the device anymore!!!

I think the only way is to see whether there is a code or secret tap to the android device, so see whether there is a chance of entering the back end- there must be a way, or else it would be difficult found an article that teaches how to revert back to the original firmware- but I guess need the people to send you the firmware inorder to have access to it. https://support.glorystartouch.com/portal/en/kb/articles/firmware-update-to-revert-to-android-default-launcher
