Accessibility in mk818B ROM

Hello.I am blind and am trying to use an MK818B device. This device identifies itself as being an MK818B both in connection to the PC and on its own screen, identifies itself as having JB 4.2.2, and seems to work fine except for the fact that the accessibility app in settings is missing. That is, on all the Android devices I have worked with, I have gone to settings, then to accessibility, to turn on the screen reader, Talkback, and the braille display program, Brailleback. I am unable to find accessibility in this device's ROM.First, I'd like to know what has been done to this ROM as to the removal of accessibility. Is the icon hidden or is it the entire service which has been chopped out? Secondly, I have an update.img file for the unit. How difficult would it be to extract this image, bake in the accessibility service, and then put the ROM on the device again? Could anyone be good enough to point me to a place where instructions for this are available focussed on the RK3066 devices?Thanks.

Accessibility in mk818B ROM

Hi horsefly,

I've come across this issue on RK3066 Sumvision Tablets. The accessibility services are there it's just that settings.apk is missing the right section. I installed a different settings.apk (sideloaded as a user app) borrowed from a PIPO tablet firmware (another RK3066 device) to enable the accessibility services I wanted. The settings.apk I used I posted on XDA - linky - Once enabled the settings.apk can be removed and the accessibility service remains active.

I can't guarantee this will work OK on your device (the apk is from a 4.1.1 firmware) so use at your own risk!. Good luck.

Thanks very much, Smurph. I eventually solved the problem I posted about by downloading quick shortcut manager (Google Store) and having a sighted person create a shortcut to accessibility services. This shortcut, from the home screen, now lets me into accessibility services from which I can turn TalkBack and BrailleBack on.Thanks again.
