(I have a Gabb Z1 Phone) Is there any way for me to transfer files to it? It has a Micro SD slot, but it doesn't work for some reason. I can take screenshots with it, and I tried connecting it to the computer. If I connect it to the computer, it reads out as a camera.
. If it showed MTP, then I could transfer files, but it doesn't. I also entered it in recovery mode, and connected it to my Windows 10 desktop computer. It didn't show up, so I clicked on "Apply Update from ADB".
When I did that, it showed up as" {serial number} sideload". If there is any way that you can help me, let me know.
