Are you someone who is practising Android related tasks such as rooting, flashing custom ROM and recovery images? Then, this piece of article would be some sort of help to your attempts. Here, we are going to discuss Migrate app which helps you to make back up and restore easily when installing a custom ROM without using a PC or other external storage or space. As you know, a complete back up is very important when engaging with rooting and other technical tasks. Let's see how to use the Migrate app
How To Root Android
Before using the app, you need to get to know about Magisk. Because Migrate app is only compatible with Magisk rooted Custom ROMs.Perhaps, you may already aware of Magisk Root which has a higher reputation as a rooting solution by now. Magisk Root belongs to the custom recovery root method and you need to flash the Magisk Zip file in TWRP custom recovery to get root access.
Migrate App Capabilities
Migrate app has been designed to simplify the custom ROM installation process by SayantanRC and It helps users to backup all the data and restore them safely without losing anything. Actually, custom ROM installation is dangerous and challenging. That is why you need to pay attention to get a complete backup. Migrate helps you to backup all your apps, app data, app permissions, SMS, Call logs and Contacts, Screen DPI and Default keyboard option and restore them on your new custom ROM conveniently and safely.
How Does It Work
First back up everything you want using the Migrate application and flash the custom ROM you prefer using TWRP recovery. Then, root the Custom ROM flashing Magisk Zip file in TWRP recovery. Next, flash the Migrate backup Zip files via TWRP custom recovery and all the data will be restored under a directory named /data/local/tmp/migrate_cache (from v2.0+) and a helper app (injected into the system). After all, reboot your Android smartphone and the newly restored Migrate helper app will pop up and ask root permission. After granting the root access, you can restore things according to your preferences with the help of Migrate helper.
