gateway3dsfirmware has been updated to v1.2, this is a new kernel update. It was said v1.2 update fix some bugs as well as added new features, following are more detailed quotated from original post :
" Support for iQue (China) and HK (Taiwan) region consoles has finally arrived !The latest Blue card GW_Installer.nds will now prompt the user to select the correct region. Consoles from the above regions will need to run the latest GW_Installer.nds.
Hardware Diagnostics and SPI reset
Due to numerous issues primarily related to third party hardware, as of GW release 1.2 and onwards
we have embedded a hardware diagnostics and verification routine into the Gateway Launcher.
This diagnostics mode is designed to :
1) Reset the GW onboard SPI FLASH. Should fix some "The game card has been removed" errors.
2) Sequentially test and verify the FPGA, SPI FLASH, and MicroSD functionality.
3) Stability verification of MicroSD cards. (Inserted into Red GW card)
Customers experiencing issues with their red card are advised to follow the steps outlined here prior to contacting their reseller. Our data has shown that a very large percentage of issues has been related to data corruption on the micro SD card. This could be from the original file used or poor quality MicroSD/writer.
For this reason we have provided a 1GB test file that should be written to the MicroSD card. If this file is detected during the diagnostics test, the GW LED will flash a hue from blue to red depending on the detected read speed (Blue for fast and progressively changing towards Red for slow). The complete 1GB file will take up to 5 minutes to be verified, at which point the LED will turn constant green.
To enter into diagnostics mode, make sure you have the latest GW release build copied to your 3DS sd card. Hold down the "L" button while triggering the "Nintendo DS Profile" entry point. The 3ds will show black/gray screens with wifi / date and battery indicators on the top screen. Insert red GW card and press "L" to start the test.
Hardware Diagnostics sequence and LED colour meaning
Test 1. FPGA RED
Test 2. SPI write test YELLOW
Test 3. SPI read test TEAL
Test 4: SD
Blue = No valid SD data
White = Fat32 partition detected
Green = 3ds ROM header found (if you are still experiencing problems please download and write our GW_testrom to your micro SD, for a full read test)
When GW_testrom is detected on the micro SD, LED will flash hue from blue to red depending on the detected read speed, at the end of a full 1G successful read of the test file the LED should turn to constant Green.
If any test fails the diagnostics will halt on that test. (So if you start diagnostics and only see a constant RED, this means the FPGA is faulty and you should contact your reseller for a replacement. Constant RED,YELLOW or TEAL is idicative of a non user repairable fault)
Please note "The game card has been removed" error is most likely caused by rom data corruption, the diagnostics tools provided here were designed to offer the end user a way to verify his/her hardware setup, primarily rom writing, please ensure a full read test is performed using the GW_testrom file prior to contacting your reseller.
1) Reset the GW onboard SPI FLASH. Should fix some "The game card has been removed" errors.
