Rooting Azpen A1050 - Android Q&A, Help & Troubleshooting

I recently purchased an Azpen A1050 tablet. It's a 10.1" screen model in 1280x800 resolution, with a quad-core Allwinner33 CPU (an ARM Cortex 7 design,) 1GB RAM, 16GB flash, and external storage via a MicroSD card. It runs Android 6.01 Marshmallow.
I've had several other Azpen models, including the A727, A741, A746 and A746g. I was able to root all of them, and Kingo Root worked on the the A741, 746, and 746g models.
Kingo bounces off, both when using the Windows host based version and the apk to root on device. (And when the Windows host program gives up, it leaves half a dozen shell instances active on the tablet and killing performance till the tablet is rebooted.)
King Root bounces off saying "tablet is not adaptive".
Framaroot's apk installer also fails.
The Towelroot apk I found fails to run. The device claims it's potentially harmful and refuses to execute it. (And there are a maze of sites claiming to offer Towelroot, but it's not clear which are legitimate. Attempts to download the apk fron developer Geohot's site fail, with a 0 byte file getting downloaded.)
Has anyone successfully rooted this device, and if so, how did you do it?
There's an option in Settings to unlock the boot loader, which means it might be possible to flash a custom ROM, but I'd prefer to avoid that unless there is no other option.
Thanks in advance.

i have 1058b 10inch azpen tablet and in developer options theres a allow the bootloader to be unlocked switch from there ive read that using adb and fastboot you can oem unlock the bootloader from a online pc with a couple of commands but i also have found no open source code for azpen so theres a few possibilities of the outcome first it should unlock then one of two things are said to happen either the system would reset to factory or it would delete the entire os so without anymore documentation i couldnt go any further as my tablet was gifted to me and still too new to take that risk but after the bootloader is unlocked kingo or king root should root the tablet if not sideloading super user apk could be possible after bootloader unlock but i havent tried any of this still debating

and i tried framaroot, towel root, kingo root, king root as well as others like you did with no results one other thing stopping me is i havent found any official azpen drivers so using above method may not work for my tablet as it may not connect to adb fastboot to run unlock commands

Thanks for the reply. As you mention, it might be possible to unlock the bootloader and proceed from there.
I'm not sure an Azpen driver would be needed for adb to work, but there's a limit to how much I want to experiment.
I bought the A1050 as a device that might replace a laptop with something smaller and lighter when traveling, My 7" models almost could, but the 7" screen size was a painful limitation.
The nice thing about the A1050 is a full sized USB port. It means I can plug in my Logitech portable keyboard without having to use an OTG adapter, or plug in a USB hub and use keyboard and mouse. (The full sized port can't be used for connecting external storage, but that's not a deal breaker. What it can do is a boon.)
I'm still working on it, but the device as stands can largely do what I want. Rooting is simply a convenience - it would let me remove some bloatware Azpen installed as system aps that can't be removed by the standard Add/Remove measures, and might let me correct a few annoyances in what Azpen did. It isn't necessary to be able to use the tablet for the intended purpose, and since it does basically work, I'm not going to try something that might break it.
I can wait to see if a rooting solution that can root without needing to unlock the bootloader appears. If I run across one, I'll post about it here. In the meantime, what I have works well enough.

lucky with the full size usb, mine just has micro, 2 sim card slots, sdcard slot of course, fm radio feature and 64gbs i like it, it could use some debloating as you say, ive been just disabling certain apps that have the option definatly needs more ram, hopefully i can use a swap file but its too new so im taking it slow and thanks for your reply im looking and will share any findings as well
much appreciation

I don't think you need a swap file, and I believe Android handles that internally. There's a Linux kernel the hood, and Android is essentially a Linux system. It just differs in the way things are set up from a desktop Linux distro.
The A1050 has 16GB of storage, of which 12 are available to the user. That gives me headroom, so I don't have to resort to something like Link2SD, which lets you carve out an ext4 slice on an external card and mount that as additional app storage. (And Link2SD requires a rooted device to work in any case.) It has a GB of RAM, and that's been adequate. While Android may have a number of processes running in the background, most of them don't take a lot of RAM. I've never seen an out-of-memory condition on my devices. The issue I ran into was not enough space in the part of the internal filesystem allocated to app storage to hold everything I wanted to install.
The full size USB port was a pleasant surprise. Dual SIM card slots sounds like yours has phone capability. That's not something I would want. It probably intended to allow connectivity when you don't have a Wifi hotspot nearby. My tablet is specifically set up to be used in local mode, working on locally stored data. It's online only to check for new versions of installed apps , and to check email on occasion when traveling. I wouldn't care about FM radio, either.
Another pleasant surprise was the microSD slot. Previous Azpen models maxed out at 32GB cards. This was a hardware thing - they used SDHC slot hardware, and that has a 32GB volume size limitation. To get higher capacity, the slot has to be SDXC.
The published specs indicated the same 32GB volume limit as other Azpen tablets. But I had a 64GB microSD card bought for another device that turned out not to support it. I popped it into the A1050, it saw if, and offered me the choice of importing it as internal storage or using it as external. Importing it would mean formatting it as ext4, the default Android filesystem, and it would be mounted by the tablet as additional internal storage. I wanted to be able to pop the card and read it in something else, and transfer files to/from it without using MTP. I chose External, it worked for a bit, and then told me a had a 64GB external card. I've seen Azpen's published specs being incorrect before, so I wasn't all that surprised they were wrong, but this was a pleasant surprise.
Front and rear facing cameras were also nice. The rear facing camera is "in a pinch", and not something I'd try to do serious photography with, but is works well enough if I just want a quick shot of something.
Azpen has a bewildering variety of models, and I do wonder who they think the audience is. Had I known going in I couldn't root the A150, I would have opted for the A1048. That has similar specs, but runs Lollipop instead of Marshmallow, and should be rootable.
The nice thing is that the tech gets steadily cheaper. The A1050 cost me $80, which is a decent price for a 10" tablet with the specs it has. A non-Azpen model would likely cost twice that. (And Azpen's list price for the A1050 is $299.95. I got mine from Micro Center who is an Azpen retail partner and apparently gets very good wholesale pricing from Azpen.)
