Problems updating to 4 01
Unfortunately, when something goes wrong (as it often does), troubleshooting requires greater experience and effort than on an unmodified device.
The Google Play Store relies on other processes that run silently in the background.
We advise using Titanium Backup, or a similar backup solution, to restore apps with data.
Don’t get me wrong; there are a lot of reasons to install a custom ROM.
Whenever you wipe the Play Store, it’s also a good idea to do the same with Google Play services and Google Services Framework.
Optionally, you may also want to wipe data for Download Manager.
If there aren’t any suitable ones nearby, wait until you’re back on your home network.
Here’s a step-by-step rundown (the process may vary slightly depending on your device and Android version): First, go to Settings. (On Android 9 Pie, choose Apps & notifications Here, choose Google Play Store.
Select Force Stop, which will kill the app’s process. On the resulting screen, tap Clear Cache to remove temporary data and hopefully fix the problem. This also wipes the cache, but essentially resets the app to its original form.
These changes can stop the Play Store from functioning.
That’s a big reason why installing custom ROMs or restoring from a backup using a custom recovery sometimes prevents the Store from working.Once wiped, restart your device and then reattempt the installation or update.
