I did all that but it still didnt work..
I got it workin after restoring google services framework with titanium.
Thanks for the help.

You did that. Excellent! But do you know how GSF affects your phone? It connects the google servers to your phone. Never uninstall that .. there was a thread somewhere.. it said "apps save to uninstall" or something. Follow that...

Nexus 4 not showing up in Google Play Devices

When I go to install an app from Google Play on my computer my Nexus 4 does not show up. I have tried running different ROM's but it still doesn't show up. I can install apps through the phone fine. Have tried clearing cache in google play services etc....
Any ideas?

1. From your tablet, head into Settings>Apps>All.
2. Search for Google Services Framework.
3. Once found, tap on it and choose “Force stop.”
4. Then choose “Clear data.”
5. Back out of Apps to your About page in Settings and check for the System update.
you might get errors while installing new apps or updating existing apps. In case you get those errors, delete all the Google accounts from your phone and configure them again.

Usually caused by custom kernel. Which rom/ kernel are you using?

I am using ROM "Dirty Unicorns". I'm guessing the kernel it came with. I will try flashing another kernel.

Try to delete Google play updates and Google play service. You can't uninstall play service natively so use 3rd apps.
Clear data on both, force close and wait until it update again/install latest apk version if you have backups.
Works for me.

This worked:
delete Google account
stop Google Framework services, clear data & cache
stop Google Play Store, clear data & cache
reboot phone
setup Google account
open Google Play Store on the phone
go to desktop browser and open Google Dashboard
open Google Play Store on desktop browser
go to my android applications, click on any of them
voilà

play store error message: 'RPC:S-7:AEC-0'

hi everyone. i have rooted using CF Root for my SM G900F
installed alliance rom fine using philz touch recovery( am now on PAC MAN ROM so i know this issue isnt ROM specific)
i am unable to install any apps via playstore or pushing to phone from online store. getting error message:
'RPC:S-7:AEC-0'
driving me crazy. have cleared data and cache from play store and google services, removed google account, rebooted, added account.
still same error message, any ideas. phone is pretty unusable without apps. gmail works, play books works, just not able to add apps.
have done all work arounds possible but no joy.
i have been able to restore apps from a titanium backup but paid versions dont register as paid and i cant update any apps
very frustrating
does anyone have any ideas before i log a support call with the google boffins?

The usual answer is to update your Google play store app. And failing that, wipe the cache, reboot and then recreate the Google account. You didn't say whether you have the latest play store app version.
Did you try resolving the issue exactly as follows?
RPC:AEC:0 error (CPU/RAM/Device/Identity failure)
First ensure that you are using the latest version of the Google Play Store app.
If the problem persists, then:
Go to settings > application > Play Store > clear data & clear cache
Go to accounts > Google > remove account
Reboot to recovery mode > wipe system cache
Reboot phone normally
Settings > account > Google > log in.

Same issue here as well can't update apps or download them either. Seems to me its a google play services error something to do with that. I'm still waiting for Google to get back to me. I have not had my account for four days now. I thought it would update its self but no joy.

yes, had a support call with google this morning. they escalated the support ticket and emailed me stupid fixes that i already told them dont work.
its a google server issue for sure
i have managed to install a titanium backup of most of my apps but the paid ones dont register as being paid and i cant update anything at the moment.

Account issue
It appears that this is an account issue. I am having the same problem on multiple devices with my Google Apps account, but my gmail account is working just fine on those devices.
Google is evidently aware of it, and its gotten a little press on Android Police. Whatever you do, don't listen to what people are saying and factory reset the device. IT doesn't help, and all it winds up doing is removing access to all of your paid / no paid apps.
A small discussion has sprung up on the Google Wallet forum here.

Definitely a play server issue. I have the same error code started about 2 days ago. It's on my s4, nexus 7 and tf201. If I log on with a different account then there is no problem. If you log in through windows to the play store then you will also not be able to see your purchased apps. I'll give them a call tomorrow if it hasn't resolved itself.

I am in the same boat. When cache clean, removing and adding account didn't help I tried factory reset. Didn't help. Rooted and went to CM. Still nothing. At that point reached Google and was told they will get back as it looks like a known issue. Not a single app on my phone right now as nothing is restored from play store. It's very annoying. Have this issue on my Nexus 4 and 7. Although I did all this on 4 only.

I just wanted to let everyone know what my fix ended up being after days of troubleshooting....
I went to my PC and went to google and looked up the Google play device manager, when on this site I chose my device and allowed it to find my device on Google maps after finding it I pressed the ring my device button and also the lock screen button and changed my password... When I did this I was then able to download stuff again....
I spoke with Google about this also and they said this error is caused when your device is not synchronized with the Google servers and what needs to be done is your device needs to be reconnected to the server, so other fixes are removing your account, uninstalling google play store updates and clearing cache, clearing cache for Google play store and restarting your device, then readding your account and attempting to download again.... Google will recommend you format your phone but I recommend not doing this cause you will lose all your apps and not be able to download them ... it did not fix my issue, I tried all of these and the first I mentioned worked for me after 5 days of issues...
Good luck all,

hi, i tried everything from above and did not work. After some more research it worked like this:
1 - . On your Android device , we go to Settings
2 - . Then Applications, and inside we go to the All tab
. 3 - Here locate and click on Google Services Framework
. 4 - Once inside we delete the cache, then We delete the data and force stop.
. 5 - repeat these operations also advise with Google services with Google Play and Play Store
. 6 - After reboot phone and attempt to download / update an application and see if everything went well .

Google services not working?!??

Recently I tried to get into Google play store it said connection error.I factory reset my Galaxy tab 4 7.0 and when I try to log in it has the same error....The model is SM T230NU. It is rooted too.

Try going into settings > apps (or application manager, whatever it's called) > all > Google Play Store and clearing data and cache.
Something else to try: in settings > security enable installation from Unknown sources, then go to apkmirror.com and download the apk file for the latest version of Google Play Store to your tablet. Open the file in a file explorer and let it install, maybe your play store is out of date

Maybe you're downloading something which is not available in your country.
If not, try factory resetting your device, might solve the problem.
But I do prefer try to download same apps on other devices like Samsung or Motorola etc., if you can download the apps from other devices and not from mi a1, you should visit service center once.

I have the exactly same problem, can't download anything vie mobile data on playstore. That happened right after installing december update :S

Agree, It messes up with GCM. ? that's why i asked him if he cleared it.

I know, I just explained it here and there - in various threads, because users are still doing such a stupid thing and then spam forum with complains.

anyone can solve this please

I solve mine by going to operators store and getting new sim card. Its' weird but it works. I had problem with my data only..

I have the same issue in Bahrain, only solution is to use a VPN and my Mi A1 is using the latest version of Android O.

UAE Mi A1 owner here, same issue just download APKpure, problem temporarily solved! been like this since 3-4 days for me.
LOL at the SIM card change thing.

jokes aside, I followed all the steps and wala, now the issue has gone away!;
