Good morning, I have an Q79 or H82 (both names are accepted) tablet and I'm unable to recover it after a reset, then, following the excellent tutorial found in this post:

I get the following answers:

When I search for the fastboot devices, I see this:

C:\Users\vramirez\Desktop\Adb-fastboot>fastboot devices
mt6582_phone    fastboot
When I look for the getvar all command, I see this:

all: Done!!
finished. total time: 0.164s
When I look for the mid and cid variables that doesn't appear in the getvar all command, I see this:

C:\Users\vramirez\Desktop\Adb-fastboot>fastboot getvar mid
finished. total time: 0.003s

C:\Users\vramirez\Desktop\Adb-fastboot>fastboot getvar cid
finished. total time: 0.003s
But, unforntunately when I look for and check the emmc, or try to erase the boot partition (the only commands that I tryed which has to be with modifying or looking for the OS and hardware)the command line puts tree suspensive dots "..." bellow the command it gets a lot of time stuck in the response of that command (until the battery of the tablet gets drained ) ant after that I get the error "unable to read...(too many links)". I've been rading and some people says that it has something to do with the cable (bad quality) but this is my second cable, and of course, when I try to recovery mode on the tablet it only shows the logo and after that the menu to select the boot mode desappears.

I'll be very grateful if any of you can help me, I'm new to develop android and I want to know as much as I can about it, and of course, to recover my tablet to use it in some projects.
