Lost files after Android Marshmallow or Nougat update? Don't worry! After reading this post, you will be able to find the most reliable way to recover the files lost after Android update which is using MiniTool Mobile Recpvery for Android.
Caution! Updating Android OS May Result in File Loss
When a new version of Android OS is available, most of you would want to make an update especially when the new version boasts of outstanding features and increased performance, right?
There are 2 ways to upgrade your Android device, including Over The Air (OTA) and From Factory Image.
In general, updating Android system over the air will not kill user data, but there are exceptions reported. For example:
"I have a bunch of photos and other files that I forgot to backup before applying the update from Lollipop to Marshmallow, and now they are gone. Do I still have a chance to recover them"
In addition, using an Android factory image to upgrade Android device will wipe all data. If users haven't backed up important files in advance, they have to suffer from data loss.
But luckily, users still have a chance to recover lost files no matter what upgrade method they choose, Over the Air or from Android Factory Images.
In this post, we will show users steps to recover missing files after a Marshmallow or Nougat update as well as instructions to backing up Android phone/tablet to both PC and Cloud.
First of all, let's see how to make Android data recovery.
Full Guide on Recovering Lost Files After Android System Update
Now matter you are updating from KitKat to Lollipop, Lollipop to Marshmallow, or Marshmallow to Nougat, there are chances to lose important files, but you can try performing operations below to recover lost files.
Method 1: Recover Missing Files from Backup
If you have a backup on SD card, Google, or other places, you can recover disappeared files without rooting your Android mobile phone or tablet. Operations should be simple, so here we do not show you detailed steps. However, if there is no backup, a piece of Android data recovery software is required.
Method 2: Recover Lost Files Using Android Data Recovery Software
Some of you may want to recover deleted files directly on Android device, but actually we suggest doing it on PC, because downloading and installing a program on Android may overwrite lost files, making data recovery difficult.
In this post, we use the freeware MiniTool Mobile Recovery for Android to recover files lost due to Android system upgrade, and it is a program running on Windows platforms.
MiniTool Mobile Recovery for Android is a free Android data recovery tool that could help Android users recover files such as Messages, Contacts, Call History, WhatsApp, photos, and videos from both internal memory and SD card.

Of course, if you just need to recover files from SD card of Android phone, you can choose Don't Install. After successful installation, 2 recovery modes are shown:
If your lost messages, contacts, photos, or other files are saved in internal memory of Android devices, please choose Recover from Phone. If they are stored on SD card, please select the module Recover from SD-Card.
How to Recover Files from Internal Memory of Android Devices
After choosing Recover from Phone, please connect your Android device to computer, and then the program will detect the connected device. Then, you'll be prompted to enable USB debugging mode if you haven't enabled it before. Please follow instructions below to enable your Android device's USB debugging mode.
Then, allow USB debugging on your Android device.
In addition, if your Android device hasn't been rooted, you'll be prompted to root it. Please view the post How to Root Your Android Device to get detailed steps.
After successful root, you will get to the 3. Device Ready to Scan window, where please choose types of files you want to recover and select one of scanning modes from Quick Scan and Deep Scan.
Firstly, you can try Quick Scan to see whether lost files are found, since this mode costs much less time. However, if quick scan fails to find needed data, please go back to the Home window and repeat previous operations, and the only difference is that you need to choose Deep Scan this time.
Then, MiniTool Mobile Recovery for Android will analyze the Android device:
After analyzing, it will scan the Android device and list all files it found. Please find and check files that need recovering and recover them to another location.
Now, users should know how to recover missing files from Android internal memory, and next let's see steps to restore data from SD card after an Android Marshmallow or Nougat update.
How to Recover Files from SD Card of Android
To make SD card data recovery, please choose Recover from SD-Card. Then, connect the SD card to computer via card reader or computer built-in card slot and click Next to continue. Of course, you can also use the Android device as a card reader to connect SD card to computer if possible. After inserting the SD card to computer, just click Next to continue.
Then, select the target SD card to scan and click Next. After that, MiniTool Mobile Recovery for Android will analyze the SD card:
Just wait patiently. Once analysis is completed, the program will scan all files saved on the SD card automatically. And after scan, all found data will be shown. At this time, please look for and check files you want to recover and click Recover button.
At last, save selected files to a specified location.
Now, SD card file recovery after Android Marshmallow or Nougat update is completed, and you can have a try.
Actually, to recover data from Android SD card, you can also try MiniTool Power Data Recovery which is a dedicated data recovery program.
With its Removable Disk Drive recovery module, you can easily restore your lost and deleted data from different kinds of digital data storage media, like USB flash drive, SD card, memory card, and more.
With the trial edition of this software, you can check whether the lost data on the Android SD card can be found by this software. Just download it by pressing the button below.
Before data recovery, you need to remove the SD card from your Android phone, insert it into the card reader, and connect it to your computer.
After installing the software on your computer, please open it and you will enter the This PC interface by default.
Then, you need to choose Removable Disk Drive module from the left list. The target SD card will be listed on the interface automatically. Just choose it and click on Scan button.
When the scanning process ends, you will see the scan result interface where you can check whether your needed files are found.
If yes, you can update this software to a full edition to recover all of them.
However, if both MiniTool Mobile Recovery for Android and Power Data Recovery failed to find your files, probably they are overwritten already. No data recovery solution is able to recover overwritten files.
So far, steps to recover files after Android update have been shown, and next let's see some tips on updating Android phone or Tablet.
3 Essential Tips on Updating Android Device
Tip 1: Backup Important Files of Android to PC or Cloud Before Update
Though in most cases users will lose nothing when they are updating Android from Lollipop to Marshmallow, Marshmallow to Nougat, etc., it's still necessary to backup crucial files, because any accident could emerge during this process.
If you do not know how to backup, please refer to the following instructions.
1) Backup Android to Cloud
Some versions of Android OS provide users with the function to backup apps, messages, contacts, and other files from device to cloud, and you may find this feature from Settings > Backup and reset or Settings > Privacy.
For more details, you can refer to the post How to Back Up an Android Phone on the Google Cloud.
Alternatively, you can backup your Android device to PC.
2) Backup Android to PC
To backup messages, contacts, call history, WhatsApp, photos, videos, and other files from Android device to PC, you need a third-party program, and MiniTool Mobile Recovery for Android is worth trying.
To backup files from internal memory of Android to PC, please choose Recover from Phone module. To backup files from SD card of Android to PC, please choose Recover from SD-Card.
Of course, you can also download MiniTool Partition Wizard and use its Copy Partition function to backup SD card to PC, which is simpler.
Tip 2: Take out SD Card Before Android Update
There is a case showing updating Android OS could make files saved on SD card lost, so you'd better take SD card out before doing the update, which is the simplest way to avoid SD data loss.
