What to Do Before Android Firmware Installation?

You know it’s time to install stock firmware on your phone when performing basic task takes too long and most of your applications keep crashing. A flashing stock ROM or a master reset, restore a device to its original system state and often, solves the issue of a malfunctioning device. By doing this, users agree to delete permanently all their data and applications encrypted on their phone. This is irreversible and can’t be undone so it is a must to back up your phone in advance. Scroll down for some feasible ways to flash ROM without losing data.

How to Backup MTK And Other Android Phone?

Make a List of What You Want to Save

There might be files on your phone that you can’t let go yet. It can be something important or valuable to you. So, before you reset it, browse through your device and take note of the stuff you have. If you can, list the data you want to keep starting from your media files, to your messages, contacts, note, documents and the applications you installed. Bear in mind that factory resetting will remove everything on your phone which is essentially similar to reformatting a drive. After securing what to backup before factory resetting Android, advance to the next section.

1. Backup

Cambridge dictionary defines backup as “ a copy of the information held on a computer that is stored separately from the computer “. This definition becomes relevant when the word ‘computer’ is substituted by the word ‘smartphone’. Before performing a factory reset, one must take a backup of the contacts, SMS, app purchases, calendar, photos, etc. Google has the technology to carry out automatic backup if the required permission has been provided. However, sometimes it is advisable to take matters in your own hands and for that, it is important to know as to what should be backed up.

a) Contacts

These include all the telephone numbers of people you communicate with. Generally, they are saved in your sim card and are visible after you reset your phone or purchase a new one, but there are times when the contacts are saved in your phone memory instead.

  1. To avoid loss of those precious contacts, Google has provided a facility of Backup & Restore which once synced will not only save your contacts but also a calendar, photos, and music to its servers. This can be achieved with two or three taps and restored back on your formatted or new device. Before resetting, ensure all your data has been backed up recently by heading over to Settings > Accounts (tap Google) > Select Google account > check everything you want to sync.
  2.  Alternatively, you can export a .vcf file to your SD card/Flash drive and import the same file on your formatted or new phone. This can be done by your default ‘Contacts’ app.

b)  SMS

If you want to view your valuable SMS texts, as they were before formatting your smartphone, the only option is to take a backup. For this, you would need a third-party app which would save all your messages on your Google drive and then restore them later. I recommend using SMS Organizer from Microsoft Corporation which would not only backup and restores your messages but also organizes them as per their content into predefined folders like spam, personal, transaction, etc.

c) App Data. Some apps like ‘WhatsApp’ provide in-app backup features where all the chats and content can be backed up on Google Drive and later restore once you install WhatsApp back on your formatted phone. Apart from some software, it is not recommended to take a backup of all apps as one of them might be the reason for the non-smooth functioning of the device which led to the factory reset in the first place.

2. Copy Files and Folders

Before resetting your smartphone, it is recommended to connect your phone to an external storage drive. A few basic mobile accessories would be required such as:

A) SD card/Flash drive with OTG connector. Make sure that the smartphone supports OTG data transfer and the drive is not less than 16 GB.

or

B) Data cable. All new chargers come in two units, a wall socket with USB Port and a wire with USB and Micro USB connector. The USB connector can be inserted into the computer’s USB port which would then access the smartphone as an external drive.

The main purpose of this would be to copy your smartphone content which includes media files like photos, audio and video files, documents like eBooks, pdf, spreadsheets, etc. and miscellaneous files like installation files (.apk), contact files (.vcf) and other app-specific files.

3. Battery percentage must be more than 70%

If you want to do a factory reset on your android phone, make sure that the phone battery is above 70% to ensure smooth formatting. If the phone runs out of power while reset, it could lead to a bricked phone.

4. List of apps and Screenshots

One of the easiest ways to restore the previous look of your smartphone is to make a list of all the important third-party apps which can be installed later by logging into the Play Store > My apps and games > Library. Also, screenshots of all the home screens and application launcher screens can help you to redesign your formatted smartphone back to the way you wanted.

5. Exit Micro SD card

The final step after taking all backups and copying all files is to remove any MicroSD card from your smartphone to avoid accidental deletion of files on the card during factory reset operation.

A factory reset is an irreversible action. One must take heed and exercise caution while carrying out this process and it is always recommended to back up your data to Google servers so that it can be restored later. Alternatively, the backup can be done on the SD card and most OEMs today provide backup facilities to their respective cloud servers as well.

If you want to backup only your SMS contacts and call log then follow below and make it with G backup for Free’


For Media Tek Phone Only

Mediatek chipset is the most common chipset that is available in the budget devices to cut the costs. Taking a backup is easy once we have a custom recovery, but if the device is unrooted the process is not a straight road. However, by following this detailed guide you can take a backup of your MediaTek powered device using this simple process.


Using MTKDroidTools, you can easily backup and restore IMEI number and NVRAM data on Android devices running MediaTek chipsets. It may work on devices with other chipsets too but I haven’t tested it.
