Part 1. Recommendations for using old systems’ phone

Sometimes there are important files you cannot afford to lose and once you lose them, you become desperate wishing that you could get them back. Well, at the recent past it has been proved to be extremely difficult for you to restore data from old phone, to retrieve contacts from old phone or even to retrieve texts from an old phone. I am going to give you a much simpler way to restore all those files and data you had on your old phone to the phone you are currently using. One can lose data in so many ways. It could be you have deleted the data, files, texts, photos or music by mistake or you lose the entire data while updating your phone’s operating system to a more appealing or comfortable one to use.

One is always anxious to do an update on their device especially to a better operating system. 6.0 marshmallow (old android system) is an operating system which has been highly rated to being better than the current android 6. Does your phone have this update? If yes then you need to be very careful when updating your current android 6 operating system to 6.0 marshmallow (old android system) or nougat 7.0 (old android system) because it has been reported that this particular update loses contacts, texts, photos and other multimedia files by upgrading lollipop to marshmallow. The following are the steps you can follow to ensure that you do not lose all your data when updating your big-brand smartphones and tablets like Samsung, Infinix, Itel, Nokia or Tecno from the current operating system to 6.0 marshmallow (old android system) or nougat 7.0 (old android system) or how to recover all the data and files if you happen to lose them.

Backup Android before getting Marshmallow update

It is very crucial that before updating your phone’s operating system, you backup your android to pc. A lot of people tend to think that backing up their data to pc before doing an update is a tiresome job, but they come to regret much later when their data is wiped out and they do not have a backup to restore it from. When doing backup use Dr. Fone Backup which is practically the best-fit android backup and recovery tool. This is how you back up your data on pc using Dr. Fone back up software;

After you have backed up your data on the windows computer you can now comfortably begin the update through the following steps;

a) Updating from Lollipop to Android Marshmallow via OTA

You are most likely to use the ‘Over the Air’ (OTA) update when updating your phone as it is the simplest and most efficient update to use. Use the following steps to complete the update using OTA;

Step1- Open the settings icon on your android phone

Step2-On the settings option, find ‘about phone’ and then tap on the ‘software update’ in order to check for the latest android operating system. (you must update your phone to the latest android operating system before updating it to 6.0 marshmallow (old android operating system) or nougat 7.0 (old android system)

Step3-Once you have completed the download, your phone will automatically restart and install the 6.0 marshmallow or nougat 7.0 (old android system)


b) Force the 6.0 android marshmallow update through factory image

If you are using android devices, and you have already done all your backups to a windows computer using Dr. Fone backup software, you can follow the following steps to achieve this kind of update;

Step 1 - If you have internet connection, download and install the latest android SDK on your windows computer from the play store.

Step 2 - Add the SDK folder using the following path; My computer > Properties > Advanced system settings > System properties > Advanced > Environment variables;

Step 3 - Enable debugging on the USB

Step 4 - Connect your phone to the computer using a USB cable and then download the factory image for your device on the computer

Step 5 – Fast-boot your phone by pressing the following buttons simultaneously; volume up, volume down and the power button

Step 6 - On the command terminal in your computer execute ‘flash-all-bat’ to install the operating system onto your phone and the necessary files

Step 7 - For security purposes lock your phone’s bootloader by returning your phone back to fast booting while still connected to your computer and then execute ‘fast boot oem lock’ from the command terminal on your windows computer.

Be 100% secure with your data when updating your phone to 6.0 android marshmallow (old android system) or nougat 7.0 (old android system) by using Dr.Fone backup software.
