IMPORTANT: Switching back to Jellybean from KitKat
The first thing to try is to press the reset button with a paper clip to turn off the tablet. You can get the tablet into flash mode manually by holding esc and pressing the power button. The tablet should show up in the flash tool if you can restore your USB connection.
Make sure you are using the original USB cable provided with the tablet. The Pipo cable has a longer micro USB port to make the best possible connection. You can't just use any USB cable.
If that doesn't work, you've possibly bricked your tablet. You can refer to this thread on how to unbrick your M6 Pro:

So I pressed the reset button and followed your instructions.
Windows makes the noise like usb device is connected but doesn't recognize the pipo.
Device Manager shows - "Unknown USB Device (Device Descriptor Request Failed)" so I tried to re-install your drivers but windows said most upto date driver is installed.
The Rockchip drivers aren't compatible with 8.1 or 10. They were designed for XP, but worked in Windows 7 and 8.
You might try a PC with an older version of Windows.

Yes, that is the reason why you can't flash...it seems that your tablet should be OK. Just try Win7.

I was wondering what tool we needed to use because I have no idea what tool you're talking about😂. Sorry. Do we also have to backup everything to switch?
I'm trying to go from your KK build to your JB build.
I've tried your procedure for my M6 pro. Erased succesfully from KK tool, close it, run JB tool... then tick loader, then run (until now all ok, loader RKAndroid found, etc.) Then it changes! "no found rkandroid rock usb" and then....no way to found it again! I cant boot and cant enter loader mode!
I've tried the manual way to enter bootloader, normal boot, recovery boot, but always black screen (the tablet was 100 charged before procedure). It does not respond....
Could you please tell me a procedure to unbrick the tablet???
Pipo Tablets can be unbricked in different ways.First try "USB Deview" on PC uninstall all RK USB Entries , uninstall Driver , reinstall , reboot and try again.
What do you call the manual Way ??? , connecting to PC and pressing the Power and Volume Button at least 45 seconds to see if the Device shows up in Tool ???
If nothing really helps you have to shorten the Nandflash ,to bring it back to life. (USB Deview run as Admin otherwise you cant uninstall the Entries)
Well, I've USB deview all ADB, RK, or rockchip related, and the device manager nor rktool are able to see nothing when I connect the M6 Pro, or try the manual (yes for me is the key combitanion you said) mode to enter bootloader mode.
After this, I've tried another RK device, a Pipo P7, and windows 7 reinstalls drivers as usually, and the tool can see it, in mass storage and in loader mode.
So, how to short the nandflash or what to do now??
