USB loaders on Wii system menu 4.3U

The following are collected from various internet resources and I take no credit or responsibility on their effects or consequences. Below is a list of softmode guide applicable to any system menu version (4.3 and below).

• complete softmod guide
• Guide: Softmod ANY Wii  

USB LOADERs can load and launch all your favorite game backups from a USB hard drive, which may contain a primary partition formatted as WBFS or FAT32 or NTFS (no need to repartition the drive for Wii at all). They will work with official firmware 4.3 with a proper cIOS (e.g. cIOS 222). The cIOS gives HomeBrew access to the USB drive and the DVD drive, among other things. This allows the USB loaders to create/run backup games on/from your USB drive. No need to downgrade the firmware to 4.1.

1. Enable Homebrew on a Wii. LetterBomb is a known IOS exploit working on system 4.3U without any game.  Download the HackMii installer V0.8 and have it ready before starting LetterBomb.
2. Install the Homebrew channel V1.0.8 as part of the HackMii installer (as well as BootMii) following the LetterBomb instruction here.
3. Restore the Trucha bug to IOS36, which enables installation of cIOS
• Download DOP-Mii V16 from here (note NOT the WiiBrew Edition) and put the DOP-Mii subfolder (containing boot.dol) under apps folder of the SD card. Start DOP-Mii via Homebrew channel.
• Follow the instruction here to restore the Trucha bug. Note when prompted for file source, select Load WAD from SD Card (instead of Downloading from NUS). The WAD files (IOS15*,IOS36*,IOS38*.wad)  can be obtained from the WeHackWii package.
• Go on with the above instruction to uninstall stub IOS 222 and make space for cIOS 222
4. Install the hermes cIOS 222, which gives USB loaders access to the USB drive and the DVD drive
• Remove all GameCube memory cards and controllers
• Download hermes cIOS Installer 5.1 and put the subfolder containing the file boot.dol under apps folder of the SD card. Start the installer from the HomeBrew channel
• Select <IOS 36> with Trucha bug to run the installer and install custom IOS 222 using IOS 38 (default).
5. USB loaders can now run properly from cIOS 222. No need to install cIOS 249.
6. Install the USB loaders (USB loader GX as an example)
• Download the USB loader GX v2.3 here and put the usbloader_gx subfolder (containing boot.dol) under apps folder of the SD card. Start it from the HomeBrew channel
• The starting IOS in the loader setting may need to be changed to IOS 222 for faster load

• Load backup games from a hard drive with only NTFS partition (instructions for USB loader GX, WiiFlow and Configurable USB Loader)
• Load backup games from a hard drive with only FAT32 partition
• Work with USB flash drive: Format the drive as FAT32 with default cluster size
• Wii USB Devices Compatibility List
• Boot Wii straight into USB loader GX with priiloader

1. Download Priiloader V0.7 here and install it from HomeBrew channel
2. Download the forwarder DOL for USB loader GX and install it within Priiloader. The forwarder may need to be named as boot.dol and placed in usbloader_gx subfolder under apps for installation. The original boot.dol should be renamed and is needed in later step.
3. In Priiloader Settings, set Autoboot to Installed file and Return to Autoboot.
4. Restore the original boot.dol of the USB loader GX (renamed in Step 2 above)
5. Wii now boots straight into USB loader GX. Want to change Priiloader settings? Power Wii on while holding down the reset button on the Wii console and it will boot into the Priiloader main menu

Notes on my Palm Pixi Plus

• Update the WebOS software without incurring data usage
  Today when I tried to activate my new Pixi plus on Page plus, it prompted me to update the WebOS software after activation and I could NOT bypass it. Since I only have two dollars balance on the account, I don't want the software update to deplete the cash balance. I powered it off at the prompt and used webdoctor to update its WebOS to 1.4.5.1 (downloaded from this link). When the device restarts after the webdoctor update, it no longer prompts me to update software and now I can turn on WiFi and turn off its data usage.
• Turn off data usage
• Tap on the green Phone button at left bottom corner to open Phone app
• Open the application menu and tap Preferences
• Under Network, set data usage to OFF
• Access the USB update mode for webdoctor
  
  • First power off the device
  • Connector the USB cable directly to a USB port of a computer but not to the device
  • Press and hold the power and volume up buttons until we see the large USB icon.
  • Connect the USB data cable to the device
• Turn on the developer mode
  
  • Type the following on the main screen after unlocking the screen
    upupdowndownleftrightleftrightbastart to launch developer mode icon
  • Press on that icon to enable developer mode. Your device will prompt you to restart in order to complete the process
• Turn on the USB passthrough/DIAG mode
  Go to the Phone app and type ##USBPASS# (##8727277#). A bar call ed "USB Passthrough Control" will appear and ask for DIAG authorization code. Enter the code generated with the SN number of the phone by PrePassThroughKeygen and configure the USB port 1 mode to DIAG (others are none).
• Back gesture in an APP
  Before I know the back gesture, I was closing the APP and re-launch it to get back to the main screen of the APP. The following is taken from the above link, "Make the back gesture from right to left anywhere in the gesture area. Back takes you up a level from a detailed view to a more general view of the application you're working in. For example, when you finish reading an email message, make the back gesture to close the message and return to your list of messages. Or when you finish writing a memo, make the back gesture to close and save the memo and return to the display of all your memos. When you make the back gesture in an application and only one screen of that app is open, you minimize the app and go back to Card view. In Web, the back gesture performs the same function as the back button on the browser, allowing you to move back through previously viewed pages."
  
• Check the recondition date and status (Reverse Logistics Support)
  Enter ##786# in the phone app and you'll see a comprehensive list of phone parameters displayed including
  
  • ACTDATE: date of activation
  • MSID
  • RECONDDATE: empty for a non-refurbished phone
  • RECONDSTATUS: no for a non-refurbished phone
  • MEID: ESN(HEX) of the phone
  • MDN: page plus phone number
  • WARRANTYDATECODE
• WebOS Quick Install (WOSQI)
  • USB mode for WOSQI: When there is a prompt on the device for the USB mode, I tap on "Just Charge". I only switch it to USB drive mode when necessary since packages won't install properly from WOSQI if the device is on USB drive mode. 
  •  Install Preware: Click on the third button (shown next) to obtain a list of packages available for directly download and installation from internet. Search for Preware and select it then click on the Install button. It should take less than a minute to finish if the device is not on the USB drive mode.
  • Uninstall packages or patches: Select the menu item Tools->Device Management (shown below) for this task.
    
    

Change MAC address of an interaface in Mandriva

First I tried the command
ifconfig eth1 hw ether 00:01:02:03:04:05
and I got the following error

SIOCSIFHWADDR: Device or resource busy
Then I tried the following command
ifconfig eth1 down hw ether 00:01:02:03:04:05 
ifup eth1
and it worked!

I also updated the file /etc/iftab with the new MAC address for eth1. Otherwise the system will be confused after a reboot.
