The homebrew and modification community has delved deeper into the recent bout of bricked Nintendo Wii U consoles, unlucky owners are seeing their systems throwing up error codes that indicate an internal memory failure. As covered on TPU almost two weeks ago, it was speculated that leaving a Wii U in a long-term state of unuse was a root cause of the problem. It is now theorized that a simple choice of memory chip is the real issue behind the corruptions, and not a case of leaving your unplugged Wii U stashed in a box somewhere.

An online database has been established on hackmd.io, and a member is collecting hard data from Wii U owners across various online communities and sources. Early indications show that consoles fitted with a Hynix eMMC are leading the pack in terms of number of system failures, Samsung-equipped models are placed in a distant second place, and the Toshiba variant is reported as having zero problems.

It has been reported by multiple users across several online communities that their Wii U consoles are no longer functioning properly. The error codes 160-0103 and 160-2155 are the dreaded indicators of memory corruption. It has been discovered that the NAND Flash within the Wii U's internal eMMC is prone to failure. According to details gleaned from teardowns of the console's hardware, Nintendo has implemented either Toshiba or Samsung flash storage boards for the various revisions of the console. There has been an uptick in the rate of bricked Wii U consoles across recent months, but the problems seem to have occurred as far back as 2015, according to archived posts on the GBA Temp forum. It is speculated that leaving the Wii U inactive for long periods of time can lead to the memory corruption issues.
