If you want to wipe all data and reset factory settings on the Samsung A12, you can do it with a hard reset. You may also need to hard reset if you use custom firmware. You always need to hard reset when swapping stock Android for custom firmware for the first time. And you should always hard reset when changing ROMs; for updating the same ROM, it is not as important.
This tutorial demonstrates how to hard reset the Samsung A12 smartphone.
- Applying a hard reset wipes all data from Android. You need to restore data from a backup if you want data to be restored, so take a backup before starting if you don’t have automatic backups turned on already.
- You may need to sign in to your Google account after the hard reset, which means you need to know your email and password associated with your Google account. You can reset your Google account password by visiting Google.com on any desktop computer.
Samsung A12 Hard Reset
You can hard reset the Samsung A12 smartphone from the Settings app and Recovery Mode. We recommend using the Settings app unless you have a specific reason not to such as the software is not working and you have to use the recovery partition or you are installing custom firmware. So here is how to hard reset from the Settings app first:
- With the Samsung A12 turned on, open the Settings app on the phone.
- Tap General management.
- Tap Reset > Factory data reset.
- Tap Reset > Delete all.
Once the device is hard reset, the Android operating system will restart and you can set up the device again.
You can also boot into Recovery Mode to hard reset the Samsung A12 smartphone. Use this method when Android is unresponsive. You may have a stock recovery partition or a custom one. If you use stock Android you will have a stock recovery partition and if you use custom firmware, you will have a custom recovery partition. The method for hard reset setting varies between each. Here is how to hard reset using the stock recovery partition first:
- With the Samsung A12 turned off, press and hold the Power + Volume Up buttons simultaneously until it enters Recovery Mode.
- From Android Recovery, press Wipe data/factory reset.
- When it asks “wipe all user data?” press Yes.
- Press Reboot system now.
The smartphone will reboot out of the Recovery Mode and restart the Android OS again where you can set up your device.
If you use custom firmware and a custom recovery image, use this guide instead:
- With the Samsung A12 turned off, boot to TWRP by pressing and holding Power + Volume Up.
- Tap Wipe.
- Wipe the data and all cache options you see in your version of TWRP.
- Tap Reboot from the main menu.
The smartphone will boot out of TWRP and restart the Android OS.
