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...

[Q] I messed up my Nexus! please help

Basically I tried to force my phone to get the 4.3 OTA update by forcing Google System Framework to stop and clearing data/cache. It didn't work and it messed up Google Play.
Another website said to delete my Google account, restart my phone, delete play store data, and then add my account back. So I did that and it let my accounts sync which is good but I still can't download anything from the play store.
How do I fix it?

Try to similarly clear data and cache from both running applications
Google play services
Google play store
Then run play store and see what happens

I have exactly the same problem for the same reason. And, tried the same suggested steps without success.
There has to be a simple way to restore the download ability from the Google Play Store without wiping everything. The download error dialogs I get are all the same: "…could not be downloaded due to an error. [Error retrieving information from server. [RPC:S-5:AEC-0]

Are there any risks in restoring my phone? I can't seem to figure it out any other way, but I am worried something bad will happen if I restore it.

by restoring do you mean restoring an earlier nandroid through recovery?
I'm afraid there are risks with everything, although restoring is normally ok, although you won't guarantee that'll resolve the issue that you've currently got, you may also lose text messages and other system changes made post restore.
You could always take a backup before restore so that you have an additional safe point to return to if you decide that option although.
I'd be tempted to re try all the changes you've already done in one go (wiping the various three apps and also removing Google account), as in the past when I've experienced play store issues it's those type of changes that have resolved it rather than restore, which I'd normally use in the event of more severe problems ie corruption, data loss or bad Rom flash.

Fixed!
I believe I solved my own problem basically with a bunch of “Clear Data”s and reboots. Nothing major lost and no restore.
1. Settings > Apps > All (flick right) and find Google apps that are not downloading. Clear data (button). Also, find Google Services Framework and its Clear data (button). Reboot.
2. Settings > Accounts > Google > tap account name to view all items sync’d. Remove account (dropdown menu). Reboot.
3. Repeat the first step including the reboot.
4. Settings > Accounts > Add an account > Google. Existing (button) and select the account you previously removed. Reboot.
5. Wait a little, the problem apps should restore and begin their downloads to sync or update.
6. For some reason other Google apps remained a problem including Maps. Repeat the Clear data steps for these and the Google Services Framework. Remove Google account again. Select the existing account again.
7. Everything should now mostly be back to normal. Locations in Maps were all still there, but downloaded maps were gone.

[Q] Error 403 of Google Play on Samsung Galaxy S4 I9502

Dear All,
For more than a week, I have been frustrating about the 403 error on my Galaxy I9502 Duos. I have searched many places on the Internet, and I still couldn't make it work. The problem is really killing me, and I spent the whole last night writing emails with and trying solutions from Google support team, and in the end, they said they couldn't help me due to that my cellphone is a rooted device. That's ridiculous! How could I have the Google Apps without rooting my I9502?
So I have tried many ways that I can find, but still, the problem is not solved, please help me and you are my last hope!
Here are the information:
1. I'm using a stock rom based on Android 4.2.2:
Baseband version: I9502ZNUCMH3
Build number: JDQ39.I9502ZNUCMH4
2. I installed below package：
gapps-jb-20130812-signed.zip
3. Methods I have tried:
3.a I have found below link in xda, and tried below methods, and it doesn't help:
http://forum.xda-developers.com/showthread.php?t=1567456
3.a.1: Wiping cache, clear data, clear cache and force stop all below components and restart:
Google Play Store, Google Play Store Service, Google Services Framework
But this doesn't work!
3.a.2: Remove Account:
And I even tried to add another google account of my family, but still doesn't work as well!
3.a.3: Reset both two APNs to the default:
Note, I mainly use WIFI. And both two APN has been reset to default. But this doesn't work!
3.a.4: Using proxy:
I have GAEProxy and Ladder Trial installed. But this doesn't work no matter the proxy is opened or closed.
3.a.5: Revert back to the old play store:
I am using the oldest play store together with gapps-jb-20130812-signed.zip, and obvious this doesn't work too.
3.a.6: Switch to another account:
I switched to another google account, but this doesn't work.
3.a.6: Factory Reset
I didn't do this yet, but I am seriously thinking about this。。。
4. Beside this problem, I also found that my browser can not access mail.google.com
And there is a similar error message:
403. That’s an error.
Your client does not have permission to get URL /2 from this server. That’s all we know.
All, I have tried all my best, and still, I can't figure out this problem. Please help me!!!!!
Thanks.

This is first time when I hear that someone needs root to access Google Play. On all of my Android devices Google Play was working WITHOUT root...
do you have any idea at all why have you rooted your phone?

Really? I really have no idea how to install Google App without root on Galaxy S4 I9502 ? Could you please shed some light on it? Thanks!
In addition, I personally think this is not a issue relate to root as my worked phoned had worked for month until this came up suddenly.

Have tried almost the same thing...
I've done almost the same things as wangmengj (except for trying another google account). Still no success.
My device is an UMI X1 :cyclops:
Also:
My google play doesn't update by himself, but I tried removing all updates (reset to version 3.3x.sumthin'), then manually installed the newest version (I believe it is 4.4.22).
Still no success.

I have no idea what're you doing and why.
First of all, to check if your Google account is OK, log in from laptop, desktop or other PC to Google Play.
Error 403 usually means that the server refuses your authentication, in other words: you do not have the credentials accepted by the server.
If using PC you'll have same error - that would mean that there is something wrong with the account.
Second, usually (it was same in case of ALL my android phones) - the Google Play was part of the ROM and was accessible as soon as I input the Google account settings. And definitely, installing the apps using the Google Play does NOT requires root, otherwise ALL android phones would be rooted as sold.

Hi,
I am also getting the same error and had done the same as the above including a factory reset. Still I am getting the same error. I can login to my account via pc but I cannot go to my google setting via my tablet's web browswer. I also realised my device is no longer listed in my google play under setting (via PC). Can someone shed some light to it?

I had the exact same problem on my I9502, and now all settled. Here's what I've done:
- Find app "Root Explorer" and install it.
- With RE, go to root/etc
- Delete the file "hosts" or simply change its name.
Then it should work!

I have had this problem for months now.
I too have been back and forth with google "support" via email, they are ****ing useless.
The issue is on THEIR end.
When I login to the play store on my computer, and I try and download an app, it throws and error immediately after clicking install - it has nothing to do with my device, the issue exists with my account on their end somewhere, but they refuse to acknowledge this and fix it, I really don't know what to do.

hi all,
is there any solution to this issue without dealing with root ?
I have already tried all the exist idea...

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 .

Error 506 when trying to install apps

Hi
I have a problem with my Note 4 (SM-N910F) since I synced my contacts from my Note 2 with my Google account.
I can't donwload apps anymore, I get the message "Error code -506" everytime on every apps.
When I try to download from Samsung apps, It tells me my device doesn't have enough storage availabe, and I still have more than 15gb left so I don't know what to do.
What I already tried : Deleting Play Store cache and data, deleting and restoring my accounts (I have 2 accounts and tried downloading from both accounts)
Thanks for the help.

What rom r u running ? KitKat or lollipop and what version and is it rooted or not ????
You are talking about both play store and Samsung store which you call Samsung apps so is it both of them or just the one ?
If its just play store then go to Settings > Apps > All > Google Play Store and clear app cache and data then clear cache and data for Google Services Framework.
Play store is depended on GSF and wont work without it so clearing one without the other wont always work!!!

Hi!
My phone is not rooted, so no ROM on it.
I can't download apps on both stores.
Already tried to clean the cache and data, nothing changed...
Thanks !

just a full wipe will solve. Try a clean rom (stock or custom).
