[ Q ] Play Store Error 491 - Shield Tablet Q&A, Help & Troubleshooting

Greetings devs and users,
I would like to request your help on fixing an issue i have been dealing with for the past week or so, my google play store seems to always give the infamous error 491 every time i want to update or install something, this rendered my play store useless and i haven't been able to fix via anything.
I have tried:
1 - wiping play's data and cache, then rebooting
2 - wiping google services framework's data, then rebooting
3 - Removing my account, rebooting and then re adding it
4 - doing the same above but wiping dalvik-cache
5 - uninstalling and then re installing the Play Store apk
All without even temporary success.
What i have observed during the fixes is that something always happens, which is that as soon as i re add my account and the play store fires up again the 32+ needed updates i have flash on the status bar and then vanish without leaving any trace, not even an error message, then when i try to update them manually they give error 491.

I had the same error for a while on my previous tablet (GT-P3113, CyanogenMod 10). Fixed it by totally reinstalling GAPPS

Craziest Google Play / Google + / Google Now Problem! Please help!

Okay... had problems with my phone and had to totally wipe and start over (lost my IMEI and ERI). Anyway I finally got that all figured out and working and then I used ODIN to flash a factory stock image (MB1). Booted up phone and tried to login to Google Play - I get "No Connection". I decided to update to MF1 and let that process go. Still - no connection. I factory reset, cleared cache & data and still get same result.
Tried almost everything I can think of and get get logged into Google play and a few other Google services. I've searched the internet up and down and have no other options I can think of!
Google Play Store says - No Connetion
Google Now say - Network Error - Check your network connection and try again
Google Plus says No Connection Couldn't connect to the server
Google Maps works fine and has all my starred locations no problem
Here are all the steps I've taken:
1) Flashed totaly different MF1 ROM through recovery after clearing & formating every folder (system/cache/data) - same problem
2) Verified date & time is CORRECT
3) Cleared Google play and services cache and data and forced closed
4) Reset phone tons of times and powered completed down for 5-10 minutes
5) Removed google account and then re-added it
6) Deleted HOSTS file in system/etc
7) Downloaded latest Google Play and Google Services and installed manually
8) Tried WIFI & 4G - no difference in errors
Maybe Google is just down right now and everyone is having a problem? I highly doubt that! Maybe google is just blocking my account?
This is the craziest problem I have ever heard of. Any help would be greatly appreciated!

Google Play 489 error

After doing all of these:
*delete all account
*cleared playstore, google services, framework cache and data
*disabling and force stop this 3
*full clean restore(after performing this, I can download all my and new apps, but when update comes and try to install it, it gives me 489 error also)
still having this annoying 489 error even I did the steps above specially on updating apps because "sometimes" downloading new app is possible without error and sometimes it does 489 error.
I have 3 gmail accounts on my G2. When I tried downloading on my account 'A' and it gives me 489 error, I switched to my account 'B' and it will download it, and when I tried to switch again on my account 'A' then tried to download new app, it will work. But this only happens rarely because most of the time it gives me 489 error.
I have one solution to download new updates, and that is uninstalling the app and installing it which is really annoying and tiring to do specially when there is 5+ apps that have new versions and like I said, sometimes downloading app is not working it gives me this hilarious 489 error.
Last time, I really want to hammer this phone, but I think my G2 has nothing to do with my problem, it is the play store.
Btw I have:
G2 D80220B KK
Dori Kernel
xposed
Titanium backed up apps(i don't think this is the problem, because my last restore of these apps is since March 2014 and all installs and updates are working fine until last week)
blocked apps by titanium
*fused location
*google search
*location services
*smart screen
*smartshare push
*smartshare.beam
*street view
*tags
*talkback
*voice mate
I hope someone can help me here. Or is it possible to install new google play APK from others phone that don't have this problem? Really need some help here.
Thanks
Trying installing a new gapps package for your android version through recovery.
Just googles gapps package for android (version e.g 4.1.2)
Flashing the wrong gapps results to such errors like yours

I'm on stock 4.4.2 with stock Gapps, and I came from fresh restore. like I said, Google play works fine until last week. ok, if it is really the gapps, I'll try to install pa gapps and we'll see. Thanks

[Q] (Google Play Store) Error retrieving information from server [RPC:S-7 :AEC-7]

Greetings,
I had some issues uninstalling xposed on my HTC One M8 that was recently updated to lollipop so I reverted back to a stock lollipop rom directly from Telus. Every time I try and download an app from the Play Store I get the following message.
"nameofapp" could not be downloaded due to an error. (Error retrieving information from server. [RPC:S-7 :AEC-7])
This is what I have tried so far:
- Clear cache on Google Play Services (Framework) and Google Play Store
- removed update from Google Play Store
- updated Play Store manually to newest APK
- rebooted in between these steps
- removed Google Account + cleared cache + all data for all Google Apps and services
Sometimes when I reboot it will let me update or download 1-3 apps, then it will just bring back that error. I'm at a loss as to what I should try as googling this error brings up the same solutions every single time. Other then this issue the phone itself appears to be functioning properly. My phone is unlocked and rooted but I do not have xposed or any other custom mods running. I'm also using the latest version of TWRP. I have also noticed that sometimes when I disconnect from wifi and attempt to download from 4G the download actually goes through. Not exactly a solution as I have limited data available to me. Any ideas?

Flash GApps via TWRP. If it doesn't help, bring your phone back to full stock, including flashing firmware + rom and make sure to format systen + data partition
before flashing the new rom.

Thanks for the help. I tried to flash the google apps but TWRP kept giving me errors that the package wasn't compatible with my phone. I located a nandroid of Telus lollipop stock and flashed that after I have formatted the system and data partitions as you have recommended. I dont believe I needed to do firmware as I have never had anything but stock firmware on the device. Everything appears to be functioning now as I can download and update from the play store once again.
Out of curiosity are you able to tell me why I encountered that issue? I cant seem to find exactly what that error even means. While i'm still very new to the android scene with flashing custom roms and device modification I have never once had that issue.
that is a "host" error, using a file manager, go to your /system/etc folder, open the "hosts" file, as a text file, and erase all.. except the local host:
Sorry bad english

Cannot update Google Play Services: Unknown error code: -501

I'm not sure if this is a Oneplus One problem or just an android problem in general but I'm having absolutely no luck anywhere and I've tried everything short of a reset so I hope this is ok to post here.
I recently updated to CM12S. I was trying someone's advice of wiping Google Play Services data and re-updating in order to fix a battery bug, but after I reset the data, I get error code -501 in the Play Store when I try to update the app. I've already tried restarting phone, and wiping cache from a bunch of services. I've reinstalled the Play Store, and rebooted multiple times as well.
I tried to install via apk, but it fails and says "App not installed".
Does anyone know what else I could try? Thanks

problem with reinstalling Google play Store

My Huawei mate 8 (latest firmware NXT-AL10 8.0.0.839) was purchased in China. I had no problem installing Google services without root. 2 days ago I could not connect to the play store anymore. I had a server error. After 2 days I thought it probably did not come from the server. I looked on the net and followed tutorials. I tried to clear the cache and data, delete my google account and put it back. Nothing works. After uninstalling Play Store, I wanted to reinstall it impossible . Whatever the version, I have this message: the system failed to install the package because it tries an authorization that it is already by some packages (in adb it does not work either). For info, all other applications google can be reinstalled without problems and I have no problem to create a Google account in the settings.
I figured if I redo the whole procedure using GSMinstaller, it should work. Big mistake, Unable to uninstall Google Play Services. The procedure stops there.
For info the application GoogleInstaller (version 2 or 3) does not work either. I have this message: "System failed to install the package because it tries an authorization that is already by some packages
So back to square one. How to reinstall the Play Store? I would like to avoid doing a factory restore because I'm not sure that on Emui_8, GSMinstaller works.
Waiting for your answers
Thank you and good day
