Fix Google Nexus 7 Deny Charging problem

If you are ready to buy and enjoy Google’s Nexus 7, we first have to warn you about something very important: the device is known to come with a bug that is known as Deny Charging. This problem is caused by the tablet’s operating system, namely its Android 4.2 Jelly Bean version.

So this is how the problem cause by this bug works: you are going to see the touchscreen of your Nexus 7 starting to flash whenever you want to charge the gadget’s pre-installed battery unit. But, after we did some research and some testing on our own a couple of days ago, we found a way to get this device rid of the pesky problem we mentioned. Read more on how to help the tablet eliminate its bug below.

Important instructions

  1. The first step of this tutorial prepared for today should go like this: take the Asus Nexus 7 and connect it to a compatible wall charger. Then proceed to the next step.
  2. Step number two looks like this: you should make sure to simultaneously press these two keys: Volume Down and Power. Now wait till the touchscreen of the tablet in your hand makes way to the bootloader menu so that you can perform the following step.
  3. For the third step you will need to play around with each of the chargers you will see appear there.
  4. Then, for step number four, you will be asked to perform the following task: tap on Volume Down; an option called Power off device will then come on the display. You will need to click on Power to have it chosen, then move on to the following step.
  5. Step five: the Nexus 7 will need to be switched off shortly after you perform the previous action.
  6. What you have to do afterwards for the sixth step is very easy: disconnect the wall charger then connect it once again for this to work.
  7. Finally, the last step is this one: wait until you spot the default battery widget. When you see it in front of your eyes at last, this will mean that the bug is no longer there and also that you can safely plug your Google Nexus 7 tablet without having to deal with any more annoying issues from this moment

Your Google Nexus 7 should now run as greatly as when you first bought it. And the Deny Charging bug should no longer bother its integrated battery. If it still does, though, then you will have to repeat the above tutorial one more time; or as many times as you need to get rid of this kind of problem.

We hope our guide offered all the necessary tips to make the battery of your Nexus 7 function optimally once more.

    Followed till step no 2 bootloader menu did not appear. In the tutorial you have not mentioned if the tablet needs to be in powers off state or sleep state or should be turned on while connecting to compatible wall charger. My nexus 7 stopped charging after 83%. I switched the tablet on to see charge status then disconnected the cable from nexus 7 and the tablet died. I could not even turn it on. This has happened before and it takes a few days to turn on. Please help
