Hi, I have a MID-756, also known as an F900, Quadcore A33, with Android 4.4.2. A bog-standard cheap tablet, but having installed a 10,000mah battery, quite a useful device that lasts for several days.
The performance isn't super-sparkly and it does appear to run out of some types of memory sometimes, with browsers prone to shutting down without warning when reading newspaper websites. So I purchased Link2SD Pro and moved as many things as possible to the internal SD card. This also allows you to set some system programs as user programs, which then enables you to move them to the SD card as well, which is very useful.
I also did this with google play store and google play services, and that is when it went wrong, as google play store no longer worked. Based on things other people suggested, I tried various things like clearing caches, but that didn't work. I tried to use the browser to go to the play store and update them, but it said things like, "App will be installed later" - but which never happened. I tried to download google play services and play store APK's from a repository and after deleting the originals I installed them from the APKs. It nearly worked - it got to checking permissions, but instead of starting the download progress bar it said, "Unfortunately google play store has stopped", or words to that effect. Based on one suggestion I tried clearing the data for services and google services framework, and then it wouldn't even connect to the store at all.
So I saved important things and then did a factory reset, under the naive impression that it would restore it to how it had arrived. I discovered that it only clears user data and programs, and does not restore system apps that you've stupidly deleted. Having reinstalled the play services and play store from the downloaded APK's it still wouldn't actually download anything as it failed at the progress bar stage with the same message as before - "Unfortunately google play has stopped".
The other thing is that after doing a complete reset the keyboard became chinese, and having to use the old 'Nokia' way of entering English using a numeric keypad is a nuisance. So I'm keen to be able to restore the Play store function so I can at least download a better keyboard.
I've tried to download the gapps file, saving it on an external SD card and installing it on its own as suggested by one person, even going to the Pico version and each time I get "E: Error in /tmp/sideload / package.zip (status error 255)", which apparently means not enough memory according to one person.
I have looked for a custom ROM to install from scratch, but there don't appear to be any for this model. I considered reinstalling the original ROM I downloaded (exdroid4.4.2_r2-a33-v2.0) but I haven't found a mid-756 driver file so my understanding is that it is highly likely to fail.
I can't now reinstall the Link2SD app in order to set the play-related apps back to system apps again either, even though I tried uninstalling and then reinstalling on my rooted phone in order to get the .APK files and then transfer them across to the tablet. It appeared that the .APK files were automatically deleted from both the app and the Pro licence app.
I'm feeling I've right royally screwed my tablet. I know it wasn't that expensive, but it is pretty useful with the massive battery so I'd really appreciate any pointers to help fix it. I've read the suggested threads but as I can't find a driver file for this device, reinstalling the whole ROM from scratch doesn't seem like a good idea. Is it safe to clear the Dalvik cache and reinstall a whole gapps package though? I'm cautious because so far clearing other caches does not seem to have improved anything and in one case made it worse.
Very grateful for any help received!
Mike
Ok, didn't get any help but finally fixed it and people might like to know how I did it:
To recap, the situation was: Rooted MID-756 / F900 tablet, having deleted play store after it stopped working when I made it a non-system app, and after doing a full reset, found that the only keyboard option was a japanese one with Nokia-style input for Western typeface. Complete nuisance to use and with hardly any even standard apps remaining after I'd previously moved them to SD card, which was then wiped when I did full reset. So, close to useless.
Solution: Use another Android 4.2 phone, and for each of the following apps, [ Google play services, play store, Link2SD, Link2SD (new)] do the following steps:
a) in Link2SD, select an app.
b) in the details screen, from the options menu, select 'share apk'. You may need to scroll the menu up if your screen doesn't show it.
c) When the share apk options come up, select 'google drive'
d) go to your PC, and in google drive, change the name to xxxxx.apk . I don't know why the .apk seems to get missed off, but you need to add it back in again.
e) Once you've done all four apps, copy all of them to a micro SD card.
f) Put the micro SD card in your tablet.
g) in a file manager, go to the external SD card, and click on the google play services.apk. This will take you through the install procedure. When it has finished installing, reboot.
h) Do the same with Link2SD and Link2SD(new). Even if it says that the licence won't verify (it will show a red triangle next to the name when the app is open), don't worry. Select google play services, and in the detail screen, from the options menu select 'convert to system app'. Then reboot again.
i) Do the same with Play Store - install apk, reboot, convert to system app using link2SD and reboot again.
f) Open Play Store. You will probably have to go through some account setting up of google play store which should be familiar to you. This time when you get to play store and try downloading or updating something it should work. If it still doesn't, do one more reboot.
You can now restore all your previous apps, including the google keyboard if you've screwed that up by doing a hard reset. You will now be able to use a proper keyboard again.
If Link2SD was not verifying the licence for the paid version, when play store is working again you should find it will now check the licence properly.
The moral of the story: Play store does not work as a user app, it needs to be a system app, so don't try to convert it to a user app in the first place.

I've seen countless threads on these 2 errors, but I just found something intriguing on my android device.
This one is a Measy U1A android stick (the ones that you connect to your TV via HDMI). A truly nice piece of hardware, but it seems to have some issues.
Since day 1 I can't install apps most of the time. Yes, *most* of the time. 80% I get the "Invalid Package file" error, another 10% of the time I get a "Package was not signed correctly", but curiously enough, a 10% of the time the packages go through and install correctly.
Of course, this gets on my nerves.
Now, I'd really want to know what's going on and I'd love some help from the true Android experts.
This is what I've already done:
Got a Log Viewer to see what was going on.
At first it said that was an error downloading (more on this later)
Then other times it said that there was no signature for X or Y file INSIDE the apk file (I remember some libraries, I was trying to install netflix on my tests)
So, I tried to tackle the download error by checking the space (df), I found that /data had few space remaining, so I cleared stuff from it. Now I have 308Mb free, more than enough to download Netflix (14Mb download). I'm talking about /data since I found out that the downloadfile-x.apk files get downloaded to /data/data/com.android.providers/downloads/cache
Tried again, nothing. Ok, so I thought that maybe there was some weird error in the /data partition. I created a directory on the sdcard portion of the stick and linked it (ln -s). Same issues. I created a directory on my external sd card and liked to it, and the same.
Now, for the weird part, and this is where I'd love some insight:
Out of 5 downloads, ES File Explorer got installed correctly, and I got a bunch of EQUALLY SIZED downloadfile-x.apk files on that directory, but NONE OF THEM HAS THE SAME MD5 SUM. Weird? Yep, but that could only mean 3 things: Either there's a problem with my wifi/network stack, or the /data, /sdcard, /mnt/extsd partitions ALL have errors in them. The 3rd option is that Perhaps Google signs every download with a different salt and that's the reason they are all different. But I DON'T THINK THE 3rd OPTION IS LOGICAL OR PRACTICAL.
Now, I don't have access to recovery here... well, I haven't tried but there's no obvious option, perhaps CWM but I don't want to risk it too much since it ran Ubuntu for a while and now that won't boot (that's another topic, unable to debug it since I can't see anything on the screen until it boots).
I've already tried:
1. Deleting Play Cache and Data, rebooting
2. Deleting Play and installing it again (it took several tries because of the same issue)
3. Factory Default and logging to my google account again
4. FIRMWARE UPGRADE (yes, I found a new firmware, it seems faster and more stable, but I still have that issue).
Now, I haven't found a memory checker or a "nand" (as you call it) checker on the app market, do these apps exist? I'd love to rule this out.
Thanks if anyone has another option, as I said, I'm out of them. The funny thing is that once the apps are installed THEY WORK FINE!!!!
Please help, I just can't spend 15 minutes to install each app that I want :laugh:
I know my way around Linux, so don't be afraid to suggest crazy things :fingers-crossed:
*The only thing I still want to do is to be able to boot Linux again and perform some tests from there*
No one?

Mexico City here.
I found a firmware update, it makes the homepage icons bigger, changes the boot screen and overall feels faster. But I still have the same error.
As for the remote control, I found a vnc server that can be run on the dongle, and any vnc viewer can be used to control it.
I got a Rikkomagic III (not S, silly me), and let me say, that thing kicks the U1A over the window, performance is great but it has no bluetooth.
I'll keep trying to find a solution for my issue, as the Rikkomagic works fine.

As of now there is only one app . Remodroid which works as per requirement
you can download it from play store. you need to install in both the Dongle and cellphone . it works well.but sluggish at times
I randomly started getting 2 notifications; one saying I had low memory, a second that I was running out of space. When I clicked on the notification, I get 'attached image' screen. (I have never clicked on the start test button, it's big, and red... It scares me!)
I've done a fair bit of searching but can't find any topics/posts (searching "speed up your Android" is a bit of a nightmare...)
So, yeah. Has anyone seen this before? I have removed the last 3-4 apps I installed, but no change. I was using L launcher until it started overriding my screen with ads for a couple of apps. This would occur when I had installed a new app via playstore. After uninstalling, those ads have gone..
Any thoughts or help will be appreciated.
Cheers,

That picture tells me you don't own your device, someone else does. For starters, reinstall your current rom with the complete wipe and I mean wiping internal sd too. Remove your simcard before rebooting. Then get root, because if you don't, that would mean that Android system owns your phone. Just because you don't have root does not mean that system apps don't: They do (and you don't). So, get root, set it up for prompt and deselect "trust system user". You don't want to trust anything. Second, get Afwall from F-Droid and allow internet only for apps you use: browser, messaging etc. Don't allow system apps to connect to the internet. I mean none. Second, don't get any app that has ads. Period. If you do, you will always end up in a situation shown on your photo. There are many more things you can do: just read this forum, but these limited steps should protect you from major threats.
Ah, bugger. Thought that may be the response...
When do I reinsert sim card? And I'm guessing I can't use the .zip of the ROM currently stored in my internal storage?
Thanks for your reply.

You can reinsert the sim card once you setup the firewall and whitelist the apps that are allowed internet access (all others - denied). You can still use zip files that contain a good rom. You can flash that rom and then format SD card before rebooting (you can also transfer known good apps to your external SD or PC and later put them back).

Okay, cool. So to confirm, you don't believe any .zip or .apk that I'm 100% sure were safe downloads (roms, gapps, playstore backup apks etc), might be infected? (They are stored in internal storage (HTC M7)). I was going to clear everything but if you believe them to be safe I'll keep some of my backed-up apps etc to save redownloading again.. (My current rom and gapps files too for that matter...)
Thanks for taking the time to help me out. :good:
Also, is there a windose virus scanner that's any good at scanning .apks etc for Android nasties??
Thanks.

There is no way I can tell you that the apps or roms you have (which are unknown to me) are safe. It is your call. There is plenty of garbage in playstore. I, for example, don't use gapps or anything Google. I have no google services framework, so there is no way for Google to know what is on my device. Google even does not know I have android: when I login to my gmail (using web browser), I get an e-mail saying someone using Linux just logged in the account). So, I would transfer internal SD somewhere else and then examine each app (you can do it in store) to see if there are any ads. Apps that have ads are no go...
Good luck.
There's not a lot of information out there for the Galaxy Core Prime on how we might debloat and save more space, so I decided to make a short tutorial that might help people with some easy steps in cleaning up their device. This guide is meant to be pretty basic and to just help point people in the right direction so that it speaks to a broader scope of Galaxy Core Prime Models, but is based specifically on the SM-G360T1. The SM-G360T is essentially the exact same phone though, so all of these steps should apply directly to that device too. Other Galaxy Core Prime models will be able to use this as well, but just be sure to read the special "NOTE" part of each step. Also, I'm sure it goes without saying, but inevitably I'll get the question, so obviously, root is required for this!
Anyhow, here we go:
1) Do a full backup in recovery before deleting system stuff. This is always a good idea just in case you delete something you're not supposed to and android stops working, then you can just go into recovery(TWRP, CWM, etc.) and restore your backup and your back to square one. It's good to do a new backup too a few days after when you're sure your deleted apps aren't causing any problems so you can restore to that slimmer version later if need be. Also, you should probably save your backup files to the external sd as you will likely have more free space there.
2) Install a debloated rom in recovery. SlimPickins is a great one for the SM-G360T1. It's basically the stock firmware for the MetroPCS Core Prime, but thanks to @Koognod we can now run Android without all the extra junk using his rom. It comes already debloated, deodexed and deknoxed, so you can just install it and not have to deal with finding all the junk to delete for yourself. It's already gone! It's also great for speeding up your bogged down phone or creating more space for your apps and media. Here is the link.
http://forum.xda-developers.com/gal...rom-slimpickins-stock-rooted-bloated-t3250883
NOTE: YOU CAN NOT INSTALL THIS ROM IF YOU DO NOT HAVE THE SM-G360T1. It should work fine on the SM-G360T too, but for anyone else just try googling or searching XDA for your "model #" and "debloat rom".
3) I recommend deleting the "PreloadInstaller" folder from "/system/app/" with a Play Store root browser. You should do this before deleting any system apps in my opinion, as this folder contains an apk that is programmed to put back a lot of the system stuff you delete(either immediately or after reboot). If you don't feel comfortable deleting this folder just yet though, then you can just move it to your external sd card for now with your browser to save space in case you ever want to move it back or just skip this step. Your choice!
NOTE: If you don't have the SM-G360T1 or SM-G360T, then your "PreloadInstaller" folder may be called something slightly different or you may not even have it at all. Just look for something similar in there. Be careful not to delete the package installer though as that's the program that allows you to install apps yourself.
4) You need an app that uninstalls system apps. I use "System App Remover(ROOT)" from the Play Store personally because all your deleted system apps actually go into a recycle bin first where they can be restored later if needed. It also tells you if the app in question is a "Key Module"(ie. proceed with serious caution).
5) Google search the internet for system stuff that's ok to delete for your device. It helps to search your model usually, but I don't think there's much info out there for the Galaxy Core Prime unfortunately, so just searching something like "Debloat Samsung Safe" can be a great resource as many Samsung phones have the same system junk.
6) Delete all the obvious stuff you don't want. This would be things like any of the MetroPCS stuff(or whatever carrier you have) or even the Galaxy app store if you don't want it. A lot of Google apps can be deleted too, though you want to be a little more careful with those as Android is pretty much based on the Google Services Framework and many Google apps are tied into the system. Generally, apps like Chrome, Docs, Drive, Hangouts, Maps(if you prefer another map application like Waze or whatever), etc. are good to go if you want. I wouldn't delete any of the core Google apps though that may handle major processes on your phone, like Calendar, possibly even Gmail or any of the ones that you don't know what they do. Deleting the stock camera, gallery, video or music player may sometimes give you problems down the line too, so I would probably keep those. You can also back all your apps up before deleting with Titanium Backup from the Play Store too in case you delete something that you need to put back later.
*NOTE: Some apps, like the Google ones for instance, may cause popup errors after you delete them. This is normal. Your phone's just looking for all those files that were just secretly running a few moments ago. All you have to do is reboot to get rid of those messages. If they still persist, then just reinstall the app.
7) Download an app to clean up that leftover mess. When you delete an app, especially with system stuff, it often leaves a bunch of folders and junk behind. Go to the Play Store and download an app that allows you to clean all that up. There's lots of good ones. I like to use one called "SD Maid" myself. It's good at cleaning up those leftover files and has a feature called "CorpseFinder" in fact that does just that. It also cleans up a lot of other things on your phone.
Anyhow, if you're a heavy power user like myself or you store a lot of music or other media on your phone in addition to 20 million apps or so and you need more space, then I hope this helps you out. Take care guys. Thanks!
Out of curiosity, how does this affect the "phone unlock" feature? In case I want to change providers?

It won't affect it at all as long as you don't delete the "Device Unlock" app. More info on unlocking your device here:

Also, you can just install SlimPickins if you want an already debloated rom.

The phone is brand new, runs Android 9 and - like the title says - won't install any apps. This happens either if I want to download apps from the store (the download happens but then I get an error message that the app can't be installed) or if I want to install an apk file from my sd card.
On the internet dozens of sites keep repeating to clear cache and data from Google store and Play services. No way! Even after a factory reset the situation doesn't change.
I also flashed the phone with its firmware ... the result stays the same.
I tried changing user account and double-checked my connection.
I will eventually return the phone to the seller, but, until then is there anything else I might try that escaped me?
Thank you
The cause for this problem ( Error 910 ) is that there is not enough available storage space.
Fix: Make some space.
try to install apps from browser (open google play on your computer and login to your play account that added to your phone ), remote installation , the apps will be installed your device , then open google play and you will be able to install apps directly from google play
Thank you jwoegerbauer and eslamdiaa2 for your replies.
Jwoegerbauer, the phone is new and no apps have been installed. I'm attaching a pic to prove there is plenty of space.
eslamdiaa2 I did try the remote installation. The app is sent to the phone but the result is the same: can't be installed (like in the picture of my opening post). Besides, I also said I can't even install apk files from my sd card.
ok, try to clear cache for google play services , and restart your phone
Been there done that. Like I said it in my opening post.
I have the same issue. Please try this code ( *#13579*# )
Thank you so much kiwi1688. That code WORKED!!! You're a life saver!!!
There may be various reasons behind this error, but for now, you can check and follow these steps whether they are working for you or not.
Clear the cache and data of the Play Store
This gives the app a fresh start and can help fix issues.
Steps are:
Open your device's Settings app.
Tap Apps & notifications See all apps.
Scroll down and tap Google Play Store.
Tap Storage Clear Cache.
Next, tap Clear data.
Re-open the Play Store and try your download again.
Thanks bracknelson but in my case it was NOT a question of clearing cache and data (which was the very first thing I have done). Odd enough I had to "enable" app installation with the code provided by kiwi1688. After entering the code a confirmation message appeared and since then I was able to install any apps.
Before that I was about to return the phone to the manufacturer because it was far from my mind there was a code to be entered. Weird!
Tldr: Two game apps by different developers are pulling up random persons' game accounts/profiles. Fresh tablet, fresh installs, etc. It should be blank Guest profiles, but I'm insta-logged in with preexisting accounts no matter what I do.
-----
I have a new, out of the box tablet, wifi-only, unrooted, with my Google account now added. I installed several games from Google Play Store, two of which are casino apps (Caesars and DoubleU). I also installed DoubleDown, and that's not giving me any issues. All three are from different developers.
Upon opening it for the first time, Caesars loads up some old dude's account. His name, photo, and progress.
DoubleU asks if I want to log in with Facebook or play as guest.... I select Play As Guest, but alas, it then pulls up some rando's account as well (not the same old dude as Caesars).
DoubleDown acts normally as you'd expect it to.
I cleared the cache and user data for the apps, uninstalled and reinstalled the apps, deleted literally everything possibly pertinent in the file directory... it's bonkers. I clicked the "log out" options in both apps, and they boot right back into these weirdo profiles.
It's not just some weird "guest" account either... I took the coins down to a particular amount, uninstalled the game, reinstalled it, and the coins were at that same amount. So it seems to be pulling from the games' servers.
I did a little test with another tablet (unrooted, wifi-only again) that I had Caesars installed on previously (guest account, working correctly). I uninstalled it, deleted everything pertinent in the file directory, etc. Reinstalled it, and behold, it remembered my Guest progress.
I'm no expert, but my guesses for possibilities for how that happens...
1. Caesars stores the guest account data on their servers tied to some internal number unique to my device
2. Same as above, but instead of a device-specific number, they know and remember the Google account used to download the game and/or the Google account signed in on the tabet
3. There was leftover data in the root directory of the tablet that wasn't wiped by clearing data and uninstalling
Regarding the 2nd option, the app doesn't show any special permissions that would allow it to know my accounts, but maybe it does anyway. It's also important to note that the 2 tablets in question are using different Google accounts.
Of course, that was all in regards to the 2nd tablet that's behaving correctly and expectedly... No matter what method Caesars et al use to remember Guest data, it doesn't explain why I'm getting non-Guest preexisting-credentials forced into my apps on the 1st tablet.
Thanks for your help! This is maybe the weirdest technical issue I've ever had.

Tldr: Two game apps by different developers are pulling up random persons' game accounts/profiles. Fresh tablet, fresh installs, etc. It should be blank Guest profiles, but I'm insta-logged in with preexisting accounts no matter what I do.

I have a new, out of the box tablet, wifi-only, unrooted, with my Google account now added. I installed several games from Google Play Store, two of which are casino apps (Caesars and DoubleU). I also installed DoubleDown, and that's not giving me any issues. All three are from different developers.

Are either of the devices pre-used before you got them?
Try clearing cache and data for app, then uninstall the app, then boot into recovery and wipe only the cache partition(s) but do not factory reset, then reboot and reinstall the game and see what happens.
Another investigative step to try is to make a backup of the apps .apk file, save it somewhere safe to be reinstalled later in this test sequence. Then, clear cache and data for the app, uninstall the app, then sign out of your Google account on your device, then reboot into recovery and wipe cache partition(s) but do not factory reset, reboot into system, do not sign in to your Google account, then use the copy of the .apk file to reinstall the app instead of installing via Playstore and see what happens.
Another thing to try is to create a dummy Google account then signin the device with the dummy account and install the game via Playstore and see what happens.

Both devices are brand new, never used before.
I don't have TWRP installed, so I'll do that and try your suggestions. And thanks for being detailed in the step-by-step process!!
Regarding the backup of the .apk file, that may be out of my skill range, not sure off hand... Would finding the same build on ApkMirror be sufficient?
Edit:
Just wanted to add some additional info.
I installed 2 more games created by those same developers. Slotomania (same company as Caesars) acts normally - no progress, starting from blank slate.
But Take5 (same company as DoubleU) boots me into yet another preexisting account - and not even the same person's as DoubleU does. Ugh.

You don't have to install TWRP, you can wipe the cache partition using stock recovery.
You can backup the .apk using MiXplorer file manager app or you can download the same build from APKmirror.
