[Please help] Hard Bricked B3-A20 Acer Tablet No Recovery
(27-10-2017, 07:34 PM)TLKiller I flashed the wrong ROM to my Acer Iconia B3-A20 tablet and now it has no recovery menu and when I plug it to charge it shows the charge icon but then it automatically switches on (without me pressing the button) then it shutdowns then restarts again and again, I tried SP flash tool but I don't have a "scatter file". Any idea of what I can do? Because In the Acer support webpage they don't give any tool to flash this tablet via USB . Thanks for your interest and sorry if my English is bad

We'll list the firmware for your device @ https:/www.hovatek.com/forum/thread-15631.html once available.
Do you have access with a working device of the same model?

First of all, thanks for your reply. And yes, I also have access to another device and it is the exact same model, my mother owns it but I can use it if necessary. So what I need to do now? Again, thanks for your help!
(28-10-2017, 01:54 PM)innageeI followed your steps but miracle box is not working with my tablet, it says none usbport. Do I need a scatter file? I've seen on youtube I can create it with MTK droid tools, should I try that?(28-10-2017, 01:08 PM)TLKiller(28-10-2017, 11:28 AM)innagee(27-10-2017, 07:34 PM)TLKiller I flashed the wrong ROM to my Acer Iconia B3-A20 tablet and now it has no recovery menu and when I plug it to charge it shows the charge icon but then it automatically switches on (without me pressing the button) then it shutdowns then restarts again and again, I tried SP flash tool but I don't have a "scatter file".

Not sure whether miracle (loader version) will detect your device, but try dumping ROM from the working Acer with it, see guide @ https:/www.hovatek.com/forum/thread-13347.html

What's the exact chipset and Android version of this tab?

Miracle Box + loader might not support that chip, neither would MTK Droid tools. Only the box version or CM II MTK would .
another option is to find an MT8163 scatter file and use it to dump the firmware of the working phone using Sp Flash tool @ https:/www.hovatek.com/forum/thread-526.html although this would require caution
