Case : Samsung P3100 hang logo problem
Remove Write Protection bug on Samsung Emmc, on P3100 as sample, using Direct ISP Connection, and updating the firmware of Emmc, prevent WP bug comeback in a week 😄
Always backup before any action, backup 512MiB is enough for common devices. So you don't have to worry about Imei, signal, etc.
