Guide The Definitive Wii U Trimming Guide

The Wii Us SD bus is quite slow, so it can't exactly take advantage of a high speed SD card, but the Wii U is just pretty slow in general.
You can mount a SATA SSD as a USB device for extra storage, but if you are using a rednand, you should get a decently sized SD card instead.

And what about the SATA Port?

 

[Lazr]

The SATA port is limited to GEN2 SATA, so the speed of a modern SSD won't really matter

GEN2 SSD is ~300MB/s. It's a waaay better than 52MB/s of SD/eMMC 4-bit buses

Someone found a manner to patch disc drive on vWii? Because i installed a HDD on Sata port and like to play some WiiWare games, and these not run on VC injects.

there are IOS patches for some of the IOSes, but atm they are still tucked away in Garys server.

Hello, I am new member and French so sorry for my translation. I would like to know if any of you have the CPL file of Power / Custom Regulators to create and assemble the pcb by JLCPCB please? Thank you for your feedback and for this great guide!

Someone tried to do undevolting o B1X Wii U? I gave a brief research and I believe that the one responsible for controlling the 1v voltage is the U1024 (Rohm BD9171FUT-GE2)But I can't find information about it, but it has a substitute with a compatible pin LV5065VB It has a datasheet. But I still can't find answers. Would anyone know how to do that?

undervolting is usually done by trial and error, slowly turning down the voltage with buck converters by like 0.1v tops and testing with a long play session/stress test. however, even if it appears to be working it could still break later on. Don’t try undervolting unless you know what you are doing and have some spare boards in case it burns out!

Do you know what causes flashing red light? Are the absence or defect in Bluetooth or WiFi cards also causes?

To test the board, what are the minimum connected items required to at least appear the blue LED (even if some error code displayed on the TV)?

Nothing. You can have none of the modules / disc drive attached and it will show a blue LED and a picture on the TV. If its blinking red with none of these attached there's an issue elsewhere on the board.

I already bypassed the Q1077 and 1078. So what should I do to force regulators to be activated (or circumvent the flashing red light error)?

Hey, this thread is the trimming guide, you should take this up on the WiiU RND in future. Since I am already responding, I notice you previously asked about undervolting, did you attempt that at all and are you currently undervolting? I would suggest you at least don't undervolt during testing.
