Android installer broken

Hi,
I think I broke my apk installer...sort of.
Since a few days I can't install any apks that are from Google Play, so I think the whole installer for external apps is broken.
Ok, I use Lucky Patcher and I think it has broken it, but only to use the pro features of Titanium and Poweramp...they don't want to recognize their keys from PlayStore for some reason or recheck them and won't find them even after reinstallation of both, app and key. I already tried it with XInstaller and with formating /system and reinstalling the OS via TWRP (running latest PA 5 legacy alpha for LG G2, but there seem to be no such issue known) but both have not helped. I only can install apps by coppying the apk manually to /data/app or /system/priv-app and restart the device. I also made a logcat log while trying to install LMT Launcher so I hope this can help to identify the problem.
If anybody knows a solution, please help, installing apps and updates the manual way is quite annoying.
EDIT: It looks like the Package Manager is trying to install apps on a non existing SD-Card. There is no possibility for an SD-Card on my G2 (only on Korean models) without USB-OTG but the ROM has the buttons in App Overview to move Apps to an SD-Card, so I think the installer tries the same. Is there a way to find out the path where it wants to install apps and Link this (with XPosed) to the real installation folder?

Latest whatsapp apk for htc explorer a310

Hi,
I am using htc explorer a310 and due to limited space i am unable to download whatsapp by upgrading play store and therefore i have tried to directly download the apk file to my phone from several websites including the whatsapp website but it didn't work. Every time i install an .apk file it either says "Application not installed" or it gets installed and when i open the app it says the version is old and an upgrade is required which is also not practicable as it would require an upgraded play store.
Please help me with a latest working apk file for htc explorer a310.
Thanks

Try apkmirror.com
If you still get the "Application not installed" message, backup your Whatsapp data by copying the Whatsapp folder (can be found on your internal storage) to either your SD card or your PC, then uninstall Whatsapp. Afterwards, install the latest version either from Play Store or apkmirror and copy the Whatsapp folder back to your internal storage. Afterwards, start Whatsapp. That's it.

How to install modded system app?

Hello,
I am trying to install a lite mod of the apps Gmail and Google. I got an apk from a trusted site (but I cannot link because the site contains copyrighted content) but when I tried to install as an apk I got a problem parsing error. I am rooted on Android 5.0.1 if that helps. I then tried to make the preinstalled Gmail and Google system apps (the Google one was under the codename velvet folder) convert to user apps, but the apps corrupted. Then, after that failed, I tried to place the apks with correct permissions in the system/priv-app folder but they both did not appear on reboot.
Please help thanks!
