☆Root required☆

Partitions backup detects all your device partitions, including Bootloader, Kernel (Boot) and any sensitive partitions like the EFS (IMEI) and Modem partition, and let you easily make a backup of them.

Partitions restoration is also supported, but recommended only for small partitions (Boot, Recovery, EFS, Modems...)

Features:
☆ Backup to SdCard or External SdCard
☆ Restore raw partition images
☆ Highlight all related IMEI/EFS partitions
☆ Support 3 backup formats :
☆☆☆ Raw partition image (Can be restored through the application)
☆☆☆ Tar archived image
☆☆☆ Compressed GZ image

Notes:
☆ The backups are saved on /Sdcard/PartitionsBackups.
☆ Do NOT leave the EFS/Modems backups on your Sdcard, make sure you keep them on a safe place
☆ It supports stock and custom Roms (CM, Omni...)
☆ Do NOT use the restoration feature for tests purposes, it is recommended to use it for small partitions only (Boot, Recovery, EFS, Modems...), you can restore other partitions backups with Fastboot, adb dd, Odin or any other flashing tool depending on which device you are using.
☆ Partial support for Mediatek devices: some partitions are not displayed because they do NOT have a specific block number for device mapping.
