我从2018年开始使用 EVPAD,最近我发现这个电视盒设备似乎有很多问题,例如视频加载滞后,电视频道有时在中间停止,甚至更糟的是那些广告在短时间内不断出现(而我就被逼重新启动视频)!
如何解决?
a)。在电视盒主屏幕,选择 “设置”,然后选择重置 (reset) 电视盒。不用担心,这很安全。
b)。接下来,等待电视盒重启并自行返回主屏幕。它将要求您使用您的Google帐户登录。请选择登录。
c)。您会发现所有的 app 都已消失。不用担心,请立即返回主屏幕。
d)。在主屏幕上,按 EVPAD 遥控器上的6868。您应该能够看到安装一些默认 app 的选项。
e)。请不要安装EVPAD App Store,因为我怀疑这是广告弹出的根本原因。
f)。安装 Saturn Live 和 Saturn Video 的 app,之后您的电视盒应该会焕然一新了。
注意:这篇文章是在我完成电视盒重置 7天后发布的。目前为止都没有广告弹出,现在视频速度也比之前流畅。
I start using EVPAD since 2018 and recently that TV BOX device seems having a lot of problems, such as, video loading is lag, TV channel sometimes stopped in the middle, even worst is those advertisements keep on appearing within short time (and I have to restart the video)!
How to Fix it?
a). Go to Settings screen, and then proceed to Reset the TV Box. Don't worry, it's safe.
b). Next, wait until the TV BOX restart and back to Home screen by itself. It will ask you to sign in using your Google account. Yes, please sign in.
c). You will notice that all apps are gone. Don't worry, please go back to Home screen now.
d). At Home screen, press 6868 on your EVPAD remote control. You should be able to see the option to install some default apps.
e). Please DO NOT install EVPAD App Store as I suspect that is the root cause of advertisement popping up.
f). Install the Saturn Live and Saturn Video apps, enjoy your TV BOX like a brand new one.
Note: This article is posted after 7 days I've done the reset on my TV BOX, there is no advertisement popping up and the video speed now is smooth.
