I like my T7 as long as it works. Light weight, nice screen and performance good.

After couple of days I own it, it starts to annoy me with wake-up issue. Tablet won't wake up after long night charging. It happens a lot, and apparently it is a common issue reported on Chinese website.

Normally you can just poke the reset hole to reboot it, but sometime that won't work either. You have to hold the reset hole longer, then long press Power button to restart machine.

But my T7 had locked at T7 logo once, won't boot up, always went into dead l, I have to go into Recovery mode to reboot the machine.

If that happened to you, here is the steps:

1. Long press the reset hole for over 5 sec at least (Tablet should not reboot when release, otherwise T7 will loop into boot logo again)
2. Hold VolumeUP and Power button together till you see the Android avatar
3. Release buttons, system will boot into Recovery mode
you will see the menu:
- reboot system now
- install zip from sdcard
- wipe data/factory reset
- wipe cache partition
- apply update from cache
4. Use VolumeUp/VolumeDown to navigate the menu, double press Power to execute selected item
5. Do wipe data and wipe Chechen (double-wipe), then reboot
6. T7 should be reset to factory status but boot in Chinese by default (take longer than normal, about 90 sec first time).
You need be able to read Chinese or with your Chinese friend's help to change default language to English or others you can understand. Or you can guess - the language setting is in Settings UI, look at the left side menu, you will see "A.." like icon, touch it then at the very top button on the right side (语言), touch it you will see English in the list.
7. Optionally, download and install ExynosAbuse and root the T7
