[Galaxy Note 3 Q&A, Help & Troubleshooting] svbarbosa:
Every other day my phone reboots by itself.

Looking at the last_kmsg log I found out that before rebooting it fails reading the data partition masterblock.

It seems I have an emmc failure.

Any ideas on how to work around the problem? Maybe change partitions with a modified PIT file isolating the bad area?

Here are the lines extracted from my last_kmsg:
