My friend there's volume buttons, but there not solder in. I had one in California, but I couldn't get the buttons to work, your better off putting a sd card slot n solder it, n watch movies and pictures, through the document app. Just gotta create a jpeg file, n it will direct you to the photo program, once there go through storage files n movie's will pop out. Good luck, in California prisons those tablets, are obsolete and no longer available for sale either. The music can be played as well too. Ok then much luck.
The tablet has areas were the volume buttons would go, just need someone to solder it for him. Tell him to talk to, the clerk for electronics class, see what he says.
There made by union supply, which is a vending company for inmates, try that.
I remember in prison someone had that same problem, the tablet won't charge, like a certain capacitor of some sort went out n can't charge through the charging slot, does anyone know about power banks that, transfer charge to battery, or know how to read the blue prints to the tablets mother board schematics. That's what this person is asking for. Like I said, when I was in prison I encountered this problem n I couldn't fix it the only way for it to work is by, charging the battery to another tablet, n once charge put it back. If anyone knows tell me I would like to know how to fix that.
The hitecker tablet from walkenherst, won't let you reset tablet, without entering password that the company put. Now there are volume buttons, like there, their u just need to look by the HDMI input area they should be next to it. If you find a way to scratch the surface, n touch it with a piece of metal, (paper clip) or bread tie, you'll activate the volume buttons. Now once you get the hang of pressing the volume buttons, go ahead n hold down n power to enter that hidden menu. Once there it will ask you to factory reset, the problem is that it won't work anyways, it's still going to be locked, but if you can figure out how to use that secret menu to mess with the Android kiosk, you might just have a chance to get somewere. Other than that, that's how far I got. Someone told me to try installing a king's Root type of program n see if that works other than that you'll need to learn how to use that Odin program. Well good luck.
It's hard to be on your phone in prison, gotta watch out for people walking n seing you using the phone, n know when the gaurds walk, which gaurds, are working today. It's a risk you take with a phone, but with a tablet it isn't because, it's legal in a way.
