Hanwang D20 upgrade crash, Hanwang e paper book D20 crash what s going on

I don't have the same situation, I upgrade normally. I'll estimate a few points to see if it's good for you.

1.There are upgrade files and update files, have you upgraded first and then updated? In order!

2.Are you sure you pressed the reset button accurately? Or the button is broken, if you press it accurately, the system will enter the upgrade again, and the picture at this time is a bit like a crash, so be patient and wait.

3.Make sure the power supply is sufficient and plugged in.

4.I don't understand which of your steps is wrong when you say this, in short, look at the explanation method, step by step.

Seriously, I don't understand the Hanwang D20 update manual, after all, the D20 is a bargain, Hanwang will not pay attention to these old goods, and will only produce some new products for us to buy. Even the instruction manual was written quickly.

Hanwang touchpad is generally okay, but considering professionalism, it feels like one person is slightly better. First of all, one book per person is lighter and more convenient to carry than Hanwang touchpad; Moreover, one person supports the original handwriting, which is currently unattainable by the Han Dynasty; Hanwang touchpad power consumption is also very fast, almost every day has to be charged, and the eyes are uncomfortable for a long time, and one person has a super long standby for 30 days, it can be used continuously for 10 hours, its 7-inch screen is just ergonomic, whether you are watching ** or watching a movie, the visual effect will be very realistic. In addition, you can automatically set the page size, font size, color, and brightness when you use it.

All fonts are in Yahei font, which is most suitable for human eye reading, and there is also a gravity sensor device (that is, it can automatically show the best display effect according to the horizontal position of the machine in your hand), which is very user-friendly.

If the error persists, we recommend that you use a card reader to copy all the resource files from the TF card to the computer for backup, and then "quickly format" the TF card, copy the upgrade package to the TF card again after the format is completed, and restart the upgrade again. After the upgrade is successful, copy the backed up resources to the TF card again.

I'm sure you're in a hurry.

1.You connect the e-paper book to the computer to see if the charging indicator can be displayed, if you can, see if it is connected to the U disk, that is, whether the U disk of the e-paper book has been detected in [My Computer]. If there is a display, please format the USB flash drive. If it doesn't appear, please follow the steps below.

2.Manually pull out the TF card on the e-paper book, connect it to the computer with a card reader, and see if there is a problem with the TF card, if the TF card can be used normally, you will destroy the files inside when you forget to safely delete the hardware, so it is best to format it to ensure that the TF card data memory is intact. Remember to copy and save the previous TF card data.

If that doesn't work, ask me and see if it needs to be repaired.

Later connected to the power reflected?
