Some help, I have an S6 Edge which is from Vodafone UK and running XXU1A0DC, I just tried to flash (XXU1AOE4 – an unbranded Saudi release) via ODIN (which I have done numerous times with S3, S4 and S5) and got stuck in Download mode at NAND write start !!!

The ROM did not flash and after a while I just restarted my phone and all is fine but still on the old ROM.

After a quick search most threads talk about partition issues and using a PIT file to recover.

Given the ROM is unbranded why the issue, have done this probably 50+ times and never had an issue.

My nexus 9 (stock, locked) is suddenly acting very strangely. Freezes, restarts!! Reset doesn't seem to fix it.

What really surprised me was that during the freezes the CPU and RAM usage were NOT high. So the freezes are probably not caused by them.

I decided to do some searching in the logs to find out the cause of the freezes. All the freezes coincided with an iowait which means the CPU is waiting for the NAND storage to respond.

Going thru Google's nexus 9 support forum, I found that most of the failed updates (bricks) were due to the updater script finding unexpected data on system partition halfway thru the update which, on a stock system, means the filesystem has been corrupted!!!

This could be due to bad encryption, drivers, or hardware. In any case, its not looking good.

I rooted my phone and wanted to flash back to stock so I can update with the OTA and re-root, but I downloaded the zip for the AT&T tar files and everything seemed to pass MD5 checks and went okay, but as soon as I hit Start, the program just continues to say NAND Write Start for over 20 minutes, and won't flash, how do I go about re-trying this without bricking my device? It's still plugged in atm in download mode.
