[Q] Rooted phone and deleted google play NEED HELP!

I rooted my phone last night using poot and super user. I downloaded a modded google play from pirate bay thinking it was gonna give me free apps. i deleted the google play that was orginally on my phone now i can't get it back. i tried factory reset. i tried downloading a google play apk but everytime i open it after download is crashes. i want to unroot my phone but dont have a usb cord and dont have google play. what do i do?!?!?!

its ok
a lot of times roms do not have a google play apk but now here is what you can do .YOU can search the web ,and install google play 4.0.25 its the new one and it is downloadable as an apk file.JUST tipe downloadandroidrom in your browser and go to apk and then go to market, click on com.android.vending .If you have any problems installing it ,try use a file explorer.

First off, we dont support piracy on xda.
To solve your problem, download a play store in apk format from sites like androidpolice etc. and push it to /system/app with permissions of rw-r-r. You are done.

Ok. Install the app directly. Download another app called link2sd. Grant superuser access. Then open app window. Click on google play. Click on actions button. see options and click "make system app". It will make it system app automatically. Then reboot your phone. If it still FC, use fix permissions option from cwm recovery.

make sure that you also have GoogleServicesFramework.apk and GoogleLoginService.APK. AFAIK you need these two as well to get the play store app to work.

superuser says my binary is outdated. when i go to update it, it crashes saying it has stopped unexpectly. on link2sd all the options under actions is launch manage reinstall unistall. i tried manage and it just took me to application settings. i hope i didnt screw up my phone rooting it last night because i cant do anything on it. google play has got to where i can go in install an app but soon as i hit accept and download it crashes. i did a factory reset last night so poot and superuser are gone. i tried to redownload superuser just now and thats when it said my binary was outdated and when i try to update it, it crashes. is this fixable or is my phone screwed up lol. i really appreciate you helping me!!!

You can disable notifications from superuser app. Also you won't loose root if you factory reset your phone. Superuser app is set as system app when you root it. Also follow what justmpm said above.

You must install the Goggle play compatible with your Android version and your phone.
Please provide the phone model, Android version and if you have a custom recovery or not,

If you are still unable to install playstore apk, i will recommend downloading gapps for your phone model. Flash them from custom recovery using install zip. This should install your playstore. No clue if it can override the pre exisiting apps. Still learning on xda.

I don't think he has a curtom recovery set up. Flashing Gapps would overwrite existing ones, but most gapps packages are configured to abort the installation if some gapps already exist.

Try this app as an alternative
Have u tried downloading 1 mobile apk its like Google play store try it

He is already on root, and perhaps if there's nowhere the solution, ome simply can't live without playstore. I will advise full system wipe with data and installing a newer custom recovery and then new rom with new gapps.

Solution?
Any proper solution for this? Running on CM12.1.

Brother sorry we couldn't help you in this case because we don't know how to fix it . One thing you can do is that Google it and you will found some better response for sure

Dude, that is the easiest thing to fix, but if the OP doesn't tell us the phone model and version i wont even bother trying to fix it. OP is inactive anyways...

Google Play Sore Error (-505) -- Lollipop

After updating to Lollipop on my Nexus 5, it restored all of my apps except for about 10. One of them is a widget that I use everyday called Simple Calendar Widget by MYCOLORSCREEN. When trying to download the app, it gives me the message "Unknown error code during application install: -505". It seems to download fine, but the message pops up during the install process. Anybody know about this issue or experiencing the same thing if you try to download this application? I also tried downloading the apk file online but that also fails to install. I can't find any info regarding this issue. Thanks.

I had this issue on certain apps as well. The dev of those apps needed to change something for it to work on Lollipop.

Code 505 is a permissions code. This typically means that the APK file already exists in your /data/app folder. You'll need to locate the APK files in question in the /data/app folder and remove them. You will need root to perform this action.
You came across this problem because you didn't do a wipe of your userdata partition when you jumped from Kitkat to Lollipop. I encountered the same issue because of that reason. I just ended up wiping and starting fresh as my phone hadn't been wiped since I got the device last November.

Are you sure? I flashed the factory image of Lollipop on my phone and it wiped everything. Afterwards, I had to also do a factory reset of my phone from the settings due to a storage issue. Why would that get left behind?
Edit: I checked (phone is rooted) and the app isn't in the /data/app folder

I spent an hour combing through Google group threads trying to get a real answer to this outstanding question. I was perplexed that only two applications of mine refused to install due to this error. The consensus was that the APK file was still there, or some remnants of data related to the application remained on the device that the Play Store service didn't like.
I ended up wiping my device twice:
Once by flashing both the userdata.img and cache.img files, which ended up giving me the storage issue bug on Lollipop. (Showing 16GB instead of 32GB)
Second by performing a factory reset from within the booted OS, which resolved the storage issue.
After that, everything was good to go. Have yet to encounter this error code again.

as long as you have adb working it can be anywhere as long as you know the path
so adb install c:\path\to\file.apk
as it happens with terminal emulator i could download the apk seperately, with other apps i'd probably download on my tablet and pull it off that

You'd have thought people testing would have installed enough apps to come across it and if google knew about it in october why not fix it

I had this issue trying to install Rom Toolbox. I uninstalled Terminal Emulator and the issue went away, probably because Terminal Emulator is included in Rom Toolbox.

How I solved it
In bootloader mode I flash from the factory image userdata and cache, then I wipe Dalvik, data and cache in TWRP after the first boot I skip the setup just too full factory data reset, in the second boot, I set up everything normal, but instead of restoring from previous devices I set it up as a new device, then I manually download the app that was giving the error, it installed without a problem.
I know is a little too much for an app, but it works for me.

I'm currently having the issue everyone mentions, except I already have ROM Toolbox Pro and was trying to install Terminal Emulator. Terminal Emulator in ROM Toolbox currently FC's on Stock (rooted) 5.0.1. But I use other features, like the Rebooter that I don't wanna sacrifice for just Terminal Emulator haha. Wish they'd fix this issue permanently

I know, that's why you can't install jackpal terminal emulator if you have ROM toolbox installed as it uses the same permissions.
Although you should read up yourself because if you did, you'd know the terminal emulator in rom toolbox force closes on lollipop on the nexus 5.

I understand this is a old thread but I fixed it a way that wasn't mentioned in this thread. Just thought I'd share for anyone googling this issue and finding this. What I did was go into the guest account and uninstall the app that was causing the issue such as snapchat. The way I caused it in the first place was installing snapchat on aptoide which installed it on both my account and the guest account and I decided I didn't want snapchat anymore so I uninstalled it but it was still there on the guest account which caused the error 505 whenever I tried to reinstall snapchat.

[APP][Updated 2015-11-12] HTC One A9 Camera/Gallery/Editor for Marshmallow GPE

I pulled the Camera (Camera2), Gallery (HMS_Gallery_GP) and Photo Editor (HMS_PhotoEnhancer_GP) apps from LlabTooFeR's A9 dump (link). I wanted to see if they'd work on my GPE-converted HTC One M8 running Android Marshmallow 6.0 (MRA58K).
Update: I've uploaded a new version that I hope works without needing to flash the APK afterwards. Additionally, at least for me, the Photo Editor is now working, including some of the Duo effects that haven't worked on my GPE for a long time. UFocus and Foregrounder don't appear to be working correctly, but at least they don't FC.
Flashable zip. I use TWRP2. Root is required.
Please note: It's been pointed out to me that the standard GPE image leaves very little space in the system partition. Not enough for the HTC apps, which are sort of large. If you're seeing that the zip isn't flashing correctly, please clear some space on your system partition (removing unwanted System G/Apps), before flashing.
Thanks to Arkaydez for some debugging.
Thanks to danial.aw for pointing out issues with GPE system partition size.
Post back with your experience. I'd like to know if it's working for everyone.

Thanks for giving it a try and feeding back. Feeling like helping me debug it?
Here's my experience when I flash it:
- When the phone restarts, there is a permission request waiting for the Gallery app.
- When you start the camera app, it requests three permissions.
- The applications and their associated libraries are installed to:
/system/priv-app/Camera2/
/system/priv-app/HMS_Gallery_GP/
/system/priv-app/HMS_PhotoEnhancer_GP/
Does your experience reflect that?
Thanks!

2 days ago I just downloaded this A9 camera from Google Play. It installed normally, for first run it asked for permission and work great. But every next open cause FC. Anyway, I think that original camera app from M8 is better, it is also to download from GP and doesn't FC.

I flashed the zip and Apps isnt shown in the menu. So I opened the zip and installed the apk's manually. Camera and Photo Editor gave FC. Gallery is opened but didnt show any pic.
Didnt work for me.
My rom is GPE Android 6.0 - Build MRA58K.H6

You can't install the apks manually, unfortunately. They need to go into priv-app, since they require system permissions. That's what's causing the FCs. If you've installed them, and they're sitting in /system/app, you can move them (root explorer, etc.) to /system/priv-app. Then at least the camera and gallery should work.

Interesting. Unfortunately, for me, when I go to Google Play, it tells me that both versions of the HTC camera (Camera and Camera2) are incompatible with my phone and won't let me install. I assumed that's because it was a GPE. If you download and install from APK Mirror, or install it from the market somehow, I think that it puts the APKs and libraries into /system/app, which will cause it to FC. The camera assumes it's pre-installed into /system/priv-app, and is therefore entitled to system permissions. When it's installed to /system/app, it makes system storage calls, which aren't allowed, and FCs.
That's why I thought the flashable zip would be the way to go.

I was able to avoid all the FC's by 1st flashing your zip and then installing the a9 cam apk from apk mirror. b

Thanks for that. I had previously installed the APK from APK mirror, so maybe there's some secret sauce missing from the zip. Does the Photo Editor work for you now, or does it still FC?

hi...what i did was to push the latest camera downloaded from htc apk site, if i m not mistaken link was provided above, into /system/priv-app, and chmod folder to 755 n file to 644 n reboot. after rebootin, i open the camera but it FC. i reinstalled the same apk, n it works ok

I just installed the apk and it works for me

i installed the zip file .and then the file from apkmirror .The camera isn't FC-ing. but it doesn't save any picture when i take one. can it be due to converting my SD into internal ?
also, when i click "reset to default". it starts FC-ing

I'm not sure. Have you tried the new (v2) zip? Did it prompt you for permissions for storage? The camera should have prompted you for 4 permissions, and the gallery for 1.

No. Although I don't know why. I'll look into it.

you can't install apps that have been signed by a different developer, and replace with the current one. metaphor, you have a girlfriend, but your trying to get another girl who looks, and smells like your current girl, but her name is different. Since your in a beta OS, you can definitely expect bugs.
have you tried Factory data reset? there may be residual files from previous OS.

If you have secure boot on disable it, restart your phone, try Again. Worked for me couple times

It's a vice versa situation. If your secure boot is on then disable it else vice versa. And reboot your phone and then install the app. It will surely install. Its not like you've a girlfriend situation?

not resolved problem

I use ESFile Explorer to copy the new APK into the folder where the old APK is located - firstly delete the old app then replace with the new app (ensure the same name is used). Some apps are hard to find so I use BKDisabler to find the exact path of the APK I want to replace.
It worked for me as I replace the Device Maintenance App on my S8+ with a newer version off APKMirror
If still having issues, the method below may work too:
TAKE A BACKUP FIRST IN CASE IT GOES TITSUP
Download AromaFM here: https://forum.xda-developers.com/showthread.php?t=1646108&page=2 ((its a file manager that doesnt install on the phone, just runs in recovery)
Download the APK to are trying to update and put it either on an sd card or in the download folder on your phone: You will need to know where the current APK is located on your phone (usually apps are located in /data/app or /system/priv-app/ or system/app/ before going to the next step...... so for this example the APK is located in /system/priv-app/camera)
Reboot into TWRP Recovery
Install AromaFM
Go to your downloaded APK and either cut or copy it
Then navigate to the /system/priv-app/camera folder and delete the old APK then paste the new APK
Reboot
Now you should have the updated APK installed

Guys, what are you trying to solve here, he didn't even state which apk he is trying to install....

Stock camera apk for Find X2 Pro

I messed up my camera by using an APK form apkmirror.com. Probably i choosed a non compatible camera. Stupid idea.
I tried them all by now and stil the camera is not working. It goes as far as the permissions for location, but then it crashes.
I really hope that someone can provide me a link for the stock camera APK for the Find X2 Pro (ColorOS 11).
Thanks in advance !

I really hope that someone can provide me a link for the stock camera APK for the Find X2 Pro (ColorOS 11).
Thanks in advance !

Try this : open camera app properties and check if you have an option to uninstall the updates.
Otherwise, factory reset of the phone should revert to stock app.

Thanks for your tips. !
I had tried the 'Uninstall updates' option already, but it isn't there unfortunately.
The factory reset is an option i want to avoid for now. Maybe later.
