if you follow these steps you have your WhatsApp with all chat history for life. Mean you can restore WhatsApp chat history and media any time even you lost your phone or whatever.
WhatsApp Messenger is a freeware, cross-platform messaging and Voice over IP (VoIP) service Founded by Jan Koum and Brian Acton owned by Facebook. It allows users to send text messages and voice messages, make voice and video calls, and share images, documents, user locations, and other media. WhatsApp’s client application runs on mobile devices but is also accessible from desktop computers, as long as the user’s mobile device remains connected to the Internet while they use the desktop app.
The service requires users to provide a standard cellular mobile number for registering with the service. In January 2018, WhatsApp released a standalone business app targeted at small business owners, called WhatsApp Business, to allow companies to communicate with customers who use the standard WhatsApp client.

Restore from a Google Drive backup
In order to successfully restore a Google Drive backup, you need to use the same phone number and Google account used to create the backup. Follow the instructions below to restore your backup:
Uninstall and reinstall WhatsApp.
Open WhatsApp and verify your number.
When prompted, tap RESTORE to restore your chats and media from Google Drive.
After the restoration process is complete, tap NEXT. Your chats will be displayed once initialization is complete.
WhatsApp will begin restoring your media files after your chats are restored.
Note: If you install WhatsApp without any prior backups from Google Drive, WhatsApp will automatically restore from your local backup file.
Restore from a local backup
If you want to use a local backup, you’ll need to transfer the files to the new phone using a computer, file explorer or SD Card.
Your phone will store up to the last seven days worth of local backup files.
Local backups will be automatically created every day at 2:00 AM and saved as a file in your phone.
If your data isn’t stored in the /sdcard/WhatsApp/ folder, you might see “internal storage” or “main storage” folders.
Restore a less recent local backup
If you want to restore a local backup that isn’t the most recent one, you’ll need to do the following:
Download a file manager app.
In the file manager app, navigate to sdcard/WhatsApp/Databases. If your data isn’t stored on the SD card, you might see “internal storage” or “main storage” instead of sdcard.
Rename the backup file you want to restore from msgstore-YYYY-MM-DD.1.db.crypt12 to msgstore.db.crypt12. It’s possible that an earlier backup might be on an earlier protocol, such as crypt9 or crypt10. Don’t change the number of the crypt extension.
Uninstall and reinstall WhatsApp.
Tap RESTORE when prompted.
WhatsApp backups no longer count against your Google Drive storage quota mean you have unlimited space on Google Drive for Whatsapp Backups.
WhatsApp backups are tied to the phone number and Google account they were created on.
WhatsApp backups that haven’t been updated in more than one year are automatically removed from Google Drive. To avoid the loss of any backups, we recommend backing up your WhatsApp data regularly.
The first backup might take a while to complete. Please leave your phone connected to a power source.
Every time you create a Google Drive backup using the same Google account, the previous backup will be overwritten. There’s no way to restore an older Google Drive backup.
Media and messages you back up aren’t protected by WhatsApp end-to-end encryption while in Google Drive.

In this post i am going to write about How to Root LG v10 H901 Android 7.0 Nougat, But before start root process for LG v10 you must have bootloader unlocked on your LG v10. So if you are confused or don’t know how to unlock bootloader on LG phones you should first reed How to unlock Bootloader on LG v10 artical. If you deviate from this procedure, and think: “I can just skip a step, or I can do this on my own Linux install”. Don’t complain if you brick your phone.
You need to download FWUL (version 2.7 or later) and burn it to a USB stick: link
Even if you have Linux, and you think you can install the dependencies, don’t. I know this works from FWUL.
PROCEDURE PART 1: Installing TWRP
Boot from your FWUL USB stick. If your PC has secureboot enabled, you will have to disable it in BIOS
Put your phone into download mode. By turning it off, hold vol up and plug in the USB cable. You do not need to touch the power button — the phone will power on and enter download mode.
Once booted successfully to FWUL, Login to FWUL. The password is: linux
Double click the LG folder can be found on the desktop
Double click on LG LAF (runningnak3d) icon and you will be at a terminal prompt.
Execute the following commands in terminal one by one. You can copy / paste them if you like.
git checkout v10-miscwrte
When you are told to, pull the USB cable, and the phone will power off. You have TWRP installed now. At this point you can flash a ROM, or Magisk or whatever you like using TWRP.
If you don’t know what to do with TWRP, and you just want to run rooted stock, this is for you….
First boot into TWRP – with the phone off, hold vol down and power at the same time. The second the LG logo appears, release power for a split second, then then press and hold power again (you never let go of vol down).
When you get a screen asking you to factory reset, you can let go of both buttons. hit vol down to select yes — two times — this will take you to TWRP.
PROCEDURE PART 2: Rooting and cleanup
Now when you are in TWRP enter command below via terminal:
If you ran step2.sh you have TWRP on recovery, and you are rooted. If you only ran step1.sh, then you have TWRP on recovery. Either way, enjoy! Subscribe via Email and Social Media for more.

I am going to write about how to fix unknown caller name problem in acr and other call recorder applications for android after Google has denied phone number access permission for all call recording apps. we are receiving lots of requests about it from our customers, they are facing unknown caller name problem from few months.
Full Working ACR Call Recording App
This is Google’s policy and only applies to the Google Play store. they are going to release fully functional version of ACR called “ACR Unchained” on other app stores such as Huawei and Samsung and keep required permissions for accessing phone number during the call.Unfortunately Google Play Store policy prevents them from providing direct apk downloads from their website.
How to fix unknown caller name?
Because of Google have full control on Google Play and Android security is being improved day by day. Google not going to allow these apps to access phone number during calls so call recording apps developers are bound to follow Google’s policy if they need to be in Google Play. but i have a solution for unknown caller name for your you today.
How it works?
As we all know that android apps developer must follow to google policies and keep apps updated as per policy changed to compliance with new Google policies. But in this case we know that previous versions application was working well. So we can find old version of call recorder app or any other app before the current version which is not working for us due to some changes in in application.
Android apps developers can’t leave Google Play store because this effect directly their earning from Android applications. Let suppose someone made a best application and selling directly from their website, will this work for them. no this will end up with failure because 99% people prefer using free applications including me.
So developers earning are totally depends on Google Adsense ads, so they are publishing apps on Google Play to get maximum downloads for their apps.
Installing working version of call recorder app
So we are also going to install old version of ACR apk to fix unknown caller name problem due to changes in new version of ACR apk. Before we move forward we must have downloaded old version of ACR application. if you still have not downloaded the application.
Installing an Android application is not a big deal but some people still don’t know about Android application installation process. we can install apps on an Android device via two methods. this first one is via copying apk file to internal memory and second one is via adb command.
Update: Now we have fixed version with latest version on Galaxy Store , so you can download directly from Samsung Galaxy Store on your Samsung phones.
1- Installing Android app from phone memory
Open File manager or My files app
Locate apk file which you wish to install
Tap on apk file and you will have install option or open with package installer

Apk file installation process will be started if still not you should go back and click on install button again to start android app installation process.
You will have Done! message on screen in few seconds.
