Flashed wrong recovery on a QTAB with no bootloader or fastboot. What can I do? Hey guys I was just tinkering, and it was stupid of me not to take a backup of any kind. Anyway, QTAB doesn't have a bootloader or fastboot menu. When I try adb reboot bootloader or fastboot, it goes to back to recovery. Now the problem with recovery is I cant use it. Home button makes selection go up and power key does nothing.. and cwm is not touch supported.

I have the stock system.img but no stock recovery. I could try another twrp recovery. But that's what i want to know how to do it.

I've googled and tried various stuff. no luck
Without knowing the exact device model you have I can only tell you to go to the website and download the appropriate firmware. Get the right file depending on your model number and read the instructions for flashing the stock firmware. This will give you a complete stock tablet back (system.img / recovery.img / boot.img etc). 

The instructions seem pretty straight forward even though the procedure is a little bit weird...anyway:

Software needed: PhoenixSuit 


  Step 1 :Open PhoenixSuit application
  
  Step 2: Choose firmware tab
  
  Step 3: Select the image file from your computer 
  
  Step 4:Unplug the qtab + Click upgrade 
  
  You  will see this message : "Upgrade Firmware to Device?" Press Yes
  
  Then you will see this message "No Device attached!" - Press Ok
  
  And press ok for the third message also
  
  
  Now long press your power button for atleast 10 seconds
  Press one hardware key except the power button and do not release
  Connect the device to the computer
  Click power key for about 10 times
  Release all keys and the device will upgrade
  
  
  If it didn't work, repeat these 5 steps
