Google Play Error 963, Nothing Works!

[reflecta]

I try all solution for the google play Error 963 and nothing works. Delete cache and userdate from playstore app, deeinstall apks with root, install first stock rom and try the solution from papka__ ... but nothing works ... i have no idea how can i resolve this ... any other idea? is there another rom with working plays

Is it really written in my post to install stock rom? Did you do initial flash from fastboot? Did you leave system without wipe and wiped rest of?

Please, could someone with working Play Store (e.g. if using AOSP rom) paste the results of the "mount" and "blkid" (requires root) commands from the device.

This is most easily done via adb.

$ adb shell
$ su
$ mount
--
$ blkid

I want to confirm if your storage is using ext4 partition or not.

EDIT:

The error in logcat when downloading anything from Play store, is this for me:

W/FileUtils( 3002): Failed to chmod(/storage/emulated/0/Android/data/com.android.vending/files/1460047643440): android.system.ErrnoException: chmod failed: EPERM (Operation not permitted)

I've tried to fool around with permissions, but still no luck.
