The ultimate guide for installing the Google Play Store on Amazon Fire tablets Updated for the Fire HD 8 10th Gen

The ultimate guide for installing the Google Play Store on Amazon Fire tablets Updated for the Fire HD 8 10th Gen

Amazon's Fire tablets are incredibly popular, mostly because they're incredibly cheap. However, none of them come with access to the Google Play Store, which is how most Android devices download and install applications. Instead, Fire tablets come bundled with the Amazon Appstore, which has a much smaller library and lacks any Google-made apps and services. No YouTube, no Chrome, and so on.
The good news is that it's not incredibly difficult to install the Play Store on a Fire tablet, and the whole process can take as little time as 10 minutes. This complete guide for installing the Play Store on Fire tablets has detailed instructions for every model produced since 2014, with added troubleshooting steps if you run into issues.

IMPORTANT INFO

  1. Remove your tablet's microSD card if you have one installed. If you don't, the Play Store and its required may be automatically installed to the microSD card, which can cause issues. You can put the card back in once you're done.
  2. There is no way to manage a Fire tablet through Google Family Link, even after the Play Store is installed.
  3. Apps installed through the Play Store might not work with Amazon FreeTime app management. I haven't personally tested this, but that's what many people have reported in the comment section.
  4. Some apps hide themselves from the Play Store on Fire tablets, because Fire tablets are not SafetyNet-certified by Google . Netflix is one app that does this. For those applications, you can try finding them on the Amazon Appstore .

Enable installation from unknown sources

The first step in this process is to enable apps to be installed from outside the Amazon Appstore. This allows you to open and install applications from downloaded APK files, which is how we'll get the Play Store running.
First, go to the main 'Home' page on your home screen and open the Settings app. Then tap the 'Security & Privacy category (older models might just say 'Security'), find the switch for 'Apps from Unknown Sources,' and turn it on.
If tapping 'Apps from Unknown Sources' brings up a list of apps, then you don't need to do anything. You may receive a popup when installing APKs, but you'll just have to tap the 'Allow' button when prompted.
Now you're ready to download and install the APKs needed to get the Google Play Store running.

Install the Play Store

The next step is to download the proper APK files for the Play Store. You technically have to install four different applications  Google Account Manager, Google Services Framework, Google Play Services, and finally the Google Play Store. The first three apps handle basic account services and add APIs, while the last app is the store itself.
Because different Fire tablets run different versions of Android with varying hardware, the exact APKs you have to install depend on what Fire tablet you have. If you're not sure which model you have, open the Settings app again, tap on 'Device Options & System' (it might also just be called 'Device Options'), and look at what is listed under 'Device Model.
For the Google Account Manager and Google Services Framework applications, find the appropriate links for your device from the table below, and tap the main 'Download APK' button on the linked page. Don't open the downloaded files yet, we'll do that later.

GOOGLE ACCOUNT MANAGER


Fire HD 10 (9th Gen), Fire 7 (9th Gen), Fire HD 8 (8th, 10th Gen)Google Account Manager v7.1.2
Fire HD 10 (7th Gen and older), Fire HD 8 (7th Gen and older), Fire 7 (7th Gen and older), Fire HD 6, Fire HDX 8.9Google Account Manager v5.1

GOOGLE SERVICES FRAMEWORK


Fire HD 10 (9th Gen), Fire HD 8 (10th Gen)Google Services Framework v9-4832352
Fire 7 (9th Gen), Fire HD 8 (8th Gen)Google Services Framework v7.1.2
Fire HD 10 (7th Gen and older), Fire HD 8 (7th Gen and older), Fire 7 (7th Gen and older), Fire HD 6, Fire HDX 8.9Google Services Framework v5.1
For these last two applications, click the link for your device, then select the version closest to the top of the list which doesn't have "beta" in the name. Again, don't open the files yet, just download them.

GOOGLE PLAY SERVICES


Fire HD 10 (9th Gen, 2019), Fire HD 8 (10th Gen)Google Play Services (64-bit ARM, nodpi, Android 9.0+)
Fire 7 (9th Gen, 2019)Google Play Services (32-bit ARM, nodpi, Android 6.0+)
Fire HD 8 (8th Gen, 2018)Google Play Services (64-bit ARM, nodpi, Android 6.0+)
Fire HD 10 (7th Gen and older), Fire HD 8 (7th Gen and older), Fire 7 (7th Gen and older), Fire HD 6, Fire HDX 8.9Google Play Services (32-bit ARM, nodpi, Android 5.0+)

GOOGLE PLAY STORE


All modelsGoogle Play Store (universal, nodpi)
Now it's time to install the apps. Find the Files app on your tablet (it might also be called 'Docs' or 'Documents') and open it. Then, find your device's Downloads folder. On most Fire tablets, this is located in the side menu.
Finding downloaded APKs on a 2020 Fire HD 8
Finding downloaded APKs on a 2018 Fire HD 8
You should see all four APK files. If not, go back and see which one you missed (or just download all of them for good measure). Also, switch to the file list view if you haven't already, so you can see the full names of each APK.
Open the apps in the below order, and when the installation is complete, press 'Done' and not 'Open'. Installing the apps out of order will cause the Play Store to not work. Also, if you have an SD card, make sure to take it out during these installations.
  1. com.google.gsf.login
  2. com.google.android.gsf
  3. com.google.android.gms
  4. com.android.vending
Once you have installed all four apps, hold down the power button, and tap 'Restart' to restart your tablet. Older tablets might only have the option to power off — if so, let the tablet shut down, then hold down on the power button to turn it back on.
Restart (or power off, and back on again) after you finish installing the Play Store.
After your Fire tablet has booted back up, open the new Play Store app from the home screen. From there, the Play Store should ask you to login with your Google account, and then finally allow you to download and install apps.

Fixes for common problems

If the Play Store or other Google apps aren't working correctly, here are some fixes for common issues.

"This account already exists on your device"

If you get the error "This account already exists on your device" when signing into Chrome or another Google app, or if the app won't detect your Google account at all, follow these steps:
  1. Completely close the app you're having issues with (e.g. swipe it away in the Recents/multi-tasking screen).
  2. Open the Settings app, tap Apps & Permissions, then select 'Manage all applications.' These options might have different names, depending on your version of Fire OS.
  3. Find the app you're having issues with in the list, tap on it, and select 'Permissions'.
  4. Switch all available permissions to 'On'. Enabling the Contacts permission alone did the trick in my testing, but you might as well enable everything for good measure.
  5. Open the app again.
In Chrome's case, you also have to open the browser, tap on the Settings menu, and tap the 'Continue as...' blue button at the top of the screen.

Troubleshooting

If you're having a different issue than the ones listed above, here are some generic troubleshooting tips.

Reboot your tablet

This might be obvious, but it's a good step to take. Hold down the power button, tap the 'Power Off' option, and turn your tablet back on by holding down the power button again. Once it has booted back up, open the Play Store from the home screen and see if it works.

Clear app data

When I initially wrote this guide, I wasn't able to sign into the Play Store until I cleared the app's local data. This will essentially reset the Play Store app to its original state, and should fix most problems you might encounter.
Open the Settings app, select the 'Apps & Notifications' section (or whatever else has 'Apps' or 'Applications' in the name), and tap 'Manage All Applications.' Find the Play Store in the list of apps and tap it.
You have to perform two steps on this info screen. First, press the 'Force Stop' button to stop the Play Store from running. Then press the 'Storage' menu option and tap 'Clear Data' (it might also be called 'Clear storage'). Now return to the Play Store app and see if it works.
If that didn't help, follow the above steps again, but restart your tablet before trying to open the Play Store. If that didn't work either, try force-stopping and clearing data for Google Play Services in addition to the Play Store.

Reset the tablet

If you still can't get the Play Store to work, your best option is probably to factory-reset your tablet and try again. Make sure you don't restore from a backup when you're setting up the tablet again, unless the backup was made before you tried to install the Play Store.

Stuff to do afterwards

Congrats, your Fire tablet now has the Google Play Store! Pat yourself on the back. Now that the hard part is over, here are some things you should do or keep in mind.

Install Google apps

Now that you have the Play Store, you can download all the Google apps you couldn't download before! Here are some suggestions  if you're reading this on your Fire tablet, the links will take you right to the app's Play Store page.

Critical 'Sign in with Apple' Bug Could Have Let Attackers Hijack Anyone's Account

Critical 'Sign in with Apple' Bug Could Have Let Attackers Hijack Anyone's Account

Apple recently paid Indian vulnerability researcher Bhavuk Jain a huge $100,000 bug bounty for reporting a highly critical vulnerability affecting its 'Sign in with Apple' system.

The now-patched vulnerability could have allowed remote attackers to bypass authentication and take over targeted users' accounts on third-party services and apps that have been registered using 'Sign in with Apple' option.

Launched last year at Apple's WWDC conference, 'Sign in with Apple' feature was introduced to the world as a privacy-preserving login mechanism that allows users to sign up an account with 3rd-party apps without disclosing their actual email addresses (also used as Apple IDs).

In an interview with The Hacker News, Bhavuk Jain revealed that the vulnerability he discovered resided in the way Apple was validating a user on the client-side before initiating a request from Apple's authentication servers.

For those unaware, while authenticating a user via 'Sign in with Apple,' the server generates JSON Web Token (JWT) containing secret information that third-party application uses to confirm the identity of the signing-in user.

Bhavuk found that though Apple asks users to log in to their Apple account before initiating the request, it was not validating if the same person is requesting JSON Web Token (JWT) in the next step from its authentication server.


Therefore, the missing validation in that part of the mechanism could have allowed an attacker to provide a separate Apple ID belonging to a victim, tricking Apple servers into generating JWT payload that was valid to sign in into a 3rd-party service with the victim's identity.

"I found I could request JWTs for any Email ID from Apple, and when the signature of these tokens was verified using Apple's public key, they showed as valid. This means an attacker could forge a JWT by linking any Email ID and gaining access to the victim's account," Bhavuk said.

The researcher confirmed The Hacker News that the vulnerability worked even if you choose to hide your email ID from the 3rd-party services and can also be exploited to sign up a new account with the victim's Apple ID.

"The impact of this vulnerability was quite critical as it could have allowed a full account takeover. Many developers have integrated Sign in with Apple since it is mandatory for applications that support other social logins. To name a few that use Sign in with Apple - Dropbox, Spotify, Airbnb, Giphy (now acquired by Facebook)," Bhavuk added.

Though the vulnerability existed on the Apple side of code, the researcher said it's possible that some services and app offering 'Sign in with Apple' to their users might have already been using a second factor of authentication that could mitigate the issue for their users.

Bhavuk responsibly reported the issue to the Apple security team last month, and the company has now patched the vulnerability.

Besides paying bug bounty to the researcher, in response, the company also confirmed that it did an investigation of their server logs and found the flaw was not exploited to compromise any account.

Is Your TikTok Account Safe Enough? Well, Just Make Sure That You've Followed These Steps

Is Your TikTok Account Safe Enough? Well, Just Make Sure That You've Followed These Steps

Dear TikTok lovers, here're some tips to make your account safer. 

Since we began to spend most of our time going online and using apps, especially during the COVID-19 lockdown, there have been several cases when hackers took that as a chance to sneak in. So, to protect your personal data, securing your social media accounts is more than essential.
With millions of users around the world, TikTok has become one of the most popular social media platforms, and having some strangers lurking around your account is one thing you never want to deal with. Therefore, the ISEA (Information Security Awareness) by MeitY has suggested some tips to make your TikTok account safer. 
Tiktok Account 1
Here're some tips to make your TikTok account safer.
Step 1: Head to the Settings section in your TikTok account.
Step 2: If you don’t like the idea of some random strangers sneaking around your account, let's switch on the “Private Account” option. Not turning it on means letting your videos be downloaded by anyone and that is a dangerous thing.
Step 3: You should also limit the commenters for your videos as cyberbullying is becoming more and more popular. 
Step 4: If you set your videos to public mode, you should filter your followers in order to protect your account from being abused or disturbed.  
Step 5: “Slitch or Duet” is another good option in case you don’t want your data to be seen by anyone but your friends. 
Step 6: Just as the commenters, you can limit the reactors for your TikTok videos as well. 
Step 7: As kids nowadays are attracted by popular apps and have the potential to expose their personal information, parents are also suggested to have a closer look at them. 
Step 8: Finally, if all of those options above still can’t stop the intruders, users can simply block or report them to the system.
