Ext4 filesystem overhead (~5-10%) is normal. Also, the Android OS reserves metadata. Conclusion: Download Wisely, Resize Responsibly The sdata tool 4GB to 16GB download is a specialized solution for Android enthusiasts who need to break free from factory storage constraints.

The sdata tool remains preferred because it modifies the physical partition table, whereas adoptable storage slows down on slow microSD cards. Error 1: “sdata image size exceeds partition limit” Solution: Your device’s eMMC has a fixed total capacity. You cannot exceed physical storage. If you have a 16GB total chip, the max userdata is ~12GB after system/reserve. Error 2: SP Flash Tool shows “STATUS_DA_HASH_MISMATCH” Solution: Disable authentication in SP Flash Tool (Scatter file → check “Disable Auth”) or use a newer DA file. Error 3: Device boots but storage still shows old size Solution: Boot to TWRP → Wipe → Advanced Wipe → Select Data → Repair/Resize File System → Swipe to resize. Error 4: “sdata tool” not found for my chipset Solution: Use sdat2img (Python) to convert sparse images to raw, then resize with resize2fs .
