[MEGATHREAD] Hiteker, UTab, Score, and other prison devices

[Scott Westen]

Can I use an external SD Card reader on my moto g? It is the prepaid Verizon edition?

I would like to transfer files to a tablet.

My friend is getting out of the big house in a couple of weeks. He has a u-tab7 from union supply, which is a locked down tablet. He said once he gets out he can't put more stuff on it.

I bet him I could do it using my phone.

Then he tells me that the tablet is locked down and he can only access it through their menu and that only allows songs etc from that company.

I am on a quest to hack that tablet. Any thoughts?

Re: Hack a u-tab7 prison edition

Did you have any luck with this in the end? My boyfriend is coming home with one soon and we're having the same problem. But I guess now they made them all get updated operating systems with a security feature that we've heard erases data from sd cards inserted with data that didn't come directly from Union Supply. Any advice?

Re: Hack a u-tab7 prison edition

Here's what I can tell you about the utab7. It has a mini USB port (not micro) and comes with a small non proprietary sdcard reader that hooks to that port. There is no on board SD card reader. There are no external buttons besides power. Union ships a 4GB SD card to the prison. On that card is a fat 32 partition with the file system offset by 4096 bytes. It appears wiped. Using an unformat utility, files show up. The two biggest files are the apk installers and music. They are sha1 aes encrypted. When the apks listed in a separate text file match, the tablet performs what I call an unwipe, then it unencrypts the files, installs them, and rewipes the card. I have the raw 200 Meg image of an unmolested 4GB card straight from Union. If anyone wants to play with the unencryption game. It's over my head, I'm at my limits here. If there's still interest, let me know.

Press send me a copy of your raw image. (Google drive link) I'd like to play around with it. Thanks.

How do you reset a u-tab7 prison tablet?

He is in Colorado. When you hit the on button the utab logo comes on the screen but then does nothing further. Can the utab be reset or rebooted to make it work once again?

Wait, how do you know this is a prison tablet? is he in prison, or did he buy it from someone in prison?

You asked about that recently I believe. If the normal methods don't work, you might try contacting the supplier for advice:

Prison? If it is prison issued, I'm sure that the prison would require that they service the device themselves.

Welcome to the forums. What do you mean by developers password?

Re: Hack a u-tab7 prison edition

Great info. Thank you. Is there a way to upload videos to this Tablet from a different sd card, without an SD card reader, that you know of?

[MEGATHREAD] Hiteker prison devices

I bought hiteker u704rc while I was incarcerated. Is there a way to open the device setting if this model don't have any volume buttons?

 

[B. Diddy]

Welcome to Android Central! What do you mean by opening the device settings? Are you talking about the system settings? The volume buttons wouldn't have anything to do with that. Is this a device that gives restricted access to the user, since it was intended for inmates?

Welcome.

What do you mean by 'unblocked'?
