3DS:Hardware test: Difference between revisions

'''3ds_hw_test''' is a <code>.firm</code> application that tests a 3DS console's RAM for errors. There are plans to expand the test so it checks more types of hardware, but so far these plans are entirely a work-in-progress.

# Power off the console and insert your SD card into your computer.

# Copy <code>3ds_hw_test.firm</code> to the root of your SD card.

# Rename <code>boot.firm</code> to <code>luma.firm</code>.

# Rename <code>3ds_hw_test.firm</code> to <code>boot.firm</code>.

# Reinsert the SD card into your console.

# Power on the console without pressing any other buttons.

# Press any button to start the test.

# When the test finishes, press any button to turn the console off and insert your SD into your computer.

# Open the newly generated <code>sd:/HWTEST.LOG</code> file in a text editor, then scroll to the end and look at the line that says <code>[ARM11] Done. ___ total errors detected.</code>.

#* If the number on this line is 0, your console's RAM is not the issue.

#* If the number on this line is not 0, your console's RAM is dying and you need to either repair or replace the motherboard.

# Delete <code>boot.firm</code> and rename <code>luma.firm</code> to <code>boot.firm</code>.

# Power off the console and insert your SD card into your computer.

# Copy <code>3ds_hw_test.firm</code> to the root of your SD card.

# Reinsert the SD card into your console.

# power on the console while holding {{B|HOME}} to enter the fastboot3DS menu.

# Select <code>[+]Boot from file...</code> -> <code>sdmc:</code> -> <code>3ds_hw_test.firm</code>.

# Press any button to start the test.

# When the test finishes, press any button to turn the console off and insert your SD into your computer.

# Open the newly generated <code>sd:/HWTEST.LOG</code> file in a text editor, then scroll to the end and look at the line that says <code>[ARM11] Done. ___ total errors detected.</code>.

#* If the number on this line is 0, your console's RAM is not the issue.

#* If the number on this line is not 0, your console's RAM is dying and you need to either repair or replace the motherboard.

# Ensure you already have a flashcart with ntrboot flashed. If you haven't flashed your flashcart with ntrboot yet, refer to [https://3ds.hacks.guide/ntrboot this page.]

# Power off the console and insert your SD card into your computer.

# Copy <code>3ds_hw_test.firm</code> to the root of your SD card.

# Rename <code>boot.firm</code> to <code>luma.firm</code>.

# Rename <code>3ds_hw_test.firm</code> to <code>boot.firm</code>.

# Reinsert the SD card into your console.

# Insert the flashcart flashed with ntrboot into your console.

# Put the magnet into position to trigger the lid sensor. Refer to [https://i.imgur.com/5e3lKe2.png this image for reference.]

#* Note, 2DS users will not need a magnet, as their device cannot physically fold. Instead, move the sleep switch to the right.

# Press and hold {{Key press|START|SELECT|X}}, then briefly press and hold the power button for 2 to 3 seconds.

# Your console should now be booted into 3ds_hw_test. If it did not boot and instead booted into the HOME menu, power off and try again. This can take a few attempts to get the magnet positioning correct.

# Press any button to start the test.

# When the test finishes, press any button to turn the console off and insert your SD into your computer.

# Open the newly generated <code>sd:/HWTEST.LOG</code> file in a text editor, then scroll to the end and look at the line that says <code>[ARM11] Done. ___ total errors detected.</code>.
