Hmm seems a little odd.
Are you able to use SPFlashTool? If you are then I would advice you to flash the ROM in this post HERE.
I would also advice you to use SuperSU HERE to root the device if that's what you want to do. Reason is that Magisk seem's not to work too well with MM 6.0 ROM's. I have tried it on a couple of phones running MM and they both seem buggy when using the Later Magisk versions. I am not 100% certain but it seems things started going wrong from about V16.
I will be uploading a Custom Stock ROM (AOSP Look and Feel) soon which removes the unnecessary junk and add's app's that will get auto updated via the play store and keep the ROM looking fresh since Lumigon is not around to update the ROM anymore.
I have also ported over Sony's Music app and libs from my Sony XA (Also a MediaTek device) along with the Sony Launcher and others stuff too so I can hopefully Share a Sony Xperia(ance) ROM also. :fingers-crossed:
I strongly advice everyone who owns a MediaTek based device to learn to use SPFlashTool it really is a invaluable tool and will make life so much easier now and in the future :good: (Search Google and youtube for help with that )
I did not plan to root the phone, I wanted just stock rom so everything would work as from factory but if there is no other option I will do anything necesary to make it work without problems as sending it back to China where they will root it anyway is not really good option. Or I will sell it on Ebay for what it is worth with the bug and will buy another one.
Thank you very much for your help and advice, I really appreciate that and I will keep watching this thread, maby the T3 will be popular for customizations and we will see what will come out of it.
