Hi everyone,
I have a Redmi 5 Plus and I need to send my warranty phone for a headset problem. Since I have photo and video and documents that I would like to delete securely, what do you advise me to do?
When, in the past, it was necessary to securely wipe data using a Mediatek Phone, I used SPFlash Tool and I formatted data partitions with zeros. In the case of Xiaomi I saw that there is no software like SPF Tool as support software. So I thought that I think I could do to delete securely all files is:
1) unlock the bootloader
2) use adb to make the dd with zeros of the relevant partitions
What do you think? Also, can I go back to relock the bootloader? when I finish to wipe? Consider that don't need to use alternative firmware but only the need to delete my files safely and 100% non-recoverable.
Thank you.
