Backing up partitions

Backing Up Partitions

The files made by the guide should not be shared unless you know what you are doing. They contain device specific info, such as the Serial Number. It's highly recommended to not share proinfo, because it's believed to have the Serial Number.

Common Utilities Required:

• Device:32GB or above sized Micro SD card
• PC: Download the release from here (under current version) and extract it

If using Windows: Utilities Required:

• PC: ADB/Fastboot Platform Tools
• PC: MTK Drivers

If using Linux: Utilities Required:

• PC: ADB utility, install by sudo apt install adb or "sudo yum install adb'

Note: you should already have USB Debugging turned on

1. Download the latest link from this website this guide first Mtk-su and extract it
2. Open a cmd/terminal
3. With your Powkiddy X18 plugged in with USB Debugging turned on, type in adb push and then drag in the mtk-su binary from explorer. (Note, this is likely under \Step 2 - Backup\adb push\mtk-su) then add /data/local/tmp to the end of it. Your command should look something like adb push (User files location on windows or location to home folder on Linux)\Step 2 - Backup\adb push\mtk-su /data/local/tmp
4. Download this script https://raw.githubusercontent.com/madpinger/x18/master/x18_partition_backup.sh huge thanks to @Madpinger for making this.
5. Follow the same procedure as 3 but instead of dragging in the location of the script (the script should be called x18_partition_backup.sh). Also, make sure you have your micro SD card in the device and that it works properly.
6. Type in adb shell
7. If the cmd says "X18:" you can proceed to run these commands

• cd /data/local/tmp
• chmod 755 mtk-su
• chmod 755 x18_partition_backup.sh
• ./mtk-su
• ./x18_partition_backup.sh (Note: the ./x18_partition_backup.sh command will take a really long time to run, as in hours, maybe even overnight, so get comfortable doing something else for a while)

8. After running all of those commands successfully, type in "exit" in the adb shell, unplug your Powkiddy X18 from your computer, and safely eject your micro SD card (the easiest way would be to turn off the device and then remove the micro SD card).
9. Plug in the micro SD to your computer. You should see all of the different partitions made using this guide on the SD.
10. Copy all of the files off of the micro SD to a folder somewhere safe. It is recommended to compress the files using a program such as 7-zip to make it into a .zip or .7z file as a lot of space is saved by doing that (likely a few GBs)
11. Keep your backed up partitions in multiple safe places as they are your tool to unbrick your device if you mess up anywhere along the line.

Entire partitions list, your files may all end with img while pictured some files is bin, but that does not matter.

Once you have all of these partitions backed up, you are prepared to continue on installing a custom rom (see guide linked): Installing Manufacturer Clean-ish Rom
