After careful comparison, I found that there are 16 apk files missing from the new firmware with 8 missing from /system/app and another 8 missing from /system/priv-app:

Our main concern is regarding the Google Play Store which in turn it requires 3 more apps in order to subscribe to Google Play Service, namely:
1. GmsCore.apk
2. GoogleLoginService.apk
3. GoogleServicesFramework.apk
4. Phonesky.apk

If you are a survivor from this year update that still managed to retain the capability of app installation, either with file manager/remote control by phone/non-stock browser/other third party app store installed, you may proceed with KingRoot installation first.

You cannot simply install them through normal procedure as they will be installed under /data/app. You just need to copy them into /system/priv-app and set their permissions accordingly, i.e. 644 (rw-r--r--) using file manager with root access such as Root Explorer HD which accommodates to TV display and responsive to remote control. You need to reboot after completing that. Voila! You have your old faithful Google Play Store and Google Settings back in no time.

You may be tempted to restore all those apps in /system/app and /system/priv-app. But I advise you better leave them off as they are all outdated and eventually will get updated in /data/app which results in a lot of space being occupied, not to mention some of the stock apps like YouTube never seem to work.

In conclusion, this is not really a third method in restoring Google Play Store which requires you gained app installation capability in the first place and then root access. The well-known method is reverting to old firmware through recovery mode which is the easiest way but you risk of being updated again unless you wipe off the update server address in Settings or never connect using LAN cable which defeats the purpose of receiving HyppTV channels. Another method is using the Huawei STB Management hacking which originated from China and you need a PC to do that. With some luck you may be able getting them connected but most of the time you don’t.
