[XDA Assist] :
Where to begin? Logic would dictate, the beginning.

I'll do my best to be brief with the backstory.

Months ago I ordered a Jide Ultratablet to use as my portable workhorse. At first things were peachy until a rather monumental lag began to manifest every 15-45 seconds. It made the device impossible to utilize in any productive fashion, so I contacted Jide and opened up a support ticket. After months (in no way an exaggeration) of barely responsive correspondence, during which I sent them a video to demonstrate the problem, they finally came back to me with an email containing a link to a compressed folder containing the Remix 2.0 images, and also a link to a rather vague and complicated tutorial on how to flash Remix 1.5 manually to a device. (In fact, I tried to include a link to the tutorial, but I am unable to since I haven't posted to the forum enough. I am happy to PM it or email it to anyone who might like to help) I can only assume I am meant to apply the same logic to the Remix 2.0 files they sent me. Seemed a bit dicey at first glance, but while I'm by no means an expert, I'm no slouch in this arena and I'm a very quick study.

Now, on to the proverbial meat and potatoes:

If you were able to contact me for a link to the tutorial in question, you will have undoubtedly seen that they indicate one should use ADB-Fastboot as a means to flash the recovery image. No real surprises there. I have ADB and Fastboot installed on my PC (Windows 10). I also have the ADB drivers installed and have confirmed the addition to my PATH. (eg: ;C:\ADB) I can also confirm that it is working fine since I am able to pull up a terminal and issue the ADB command and it gives me the usual wall of commands. The problem is that my device (Ultratablet) is not being seen by ADB. I have checked my USB drivers and they are all up to date and installed properly. My PC sees the device no problem and there is no indication of any sort of connection error. I've also tried different cables and ports. Yet, I can't access it via ADB and thus am unable to issue commands to my device such as "adb reboot bootloader" or "fastboot reboot-bootloader".

My next logical approach was to attempt forcing the device into fastboot mode using the hardware button combination, which is not listed specifically for the Ultratablet anywhere, I might add. (Power key + Volume up) It brings me to a boot options menu with the selections "Continue/Fastboot Protocol/Recovery Kernel/Reboot/Poweroff/Forced Recovery". Ateempting to select Fastboot Protocol causes the display to shut off for a moment, the device to vibrate once, and then the display to turn back on back at the same menu full of selections.

So, in summary, I am expected to flash the device using fastboot and yet I can't even get the device into fastboot mode, let alone issue commands from my PC terminal. As I highlighted near the beginning, teh Jide support team is incredibly unresponsive and not overly helpful. I have notified them of this same set of issues, but I don't expect to hear back in any expedient fashion and I thought one of the mighty members here on XDA might be able to help me come up with a next step in the meantime. I'd cerainly love to be able to use my shiny new tablet.

In any case, thank you for your time.

Kind regards.
