Try disabling and re-enabling emuMMC to see if it fixes the configuration.
(like an RCM Loader, web-payload injector, or smartphone app) with the newly downloaded hekate_ctcaer_X.X.X.bin payload file. If using an RCM Loader dongle, ensure you rename the file to payload.bin inside the correct folder. Fix 2: Repair a pkg1 and pkg2 Firmware Mismatch
While the error is often consistent, it can manifest in a few different ways depending on your setup. You might see:
If a clean installation fails, the underlying storage media may be corrupted. pkg2 read failed failed to launch hos
: The console's primary boot stage ( pkg1 , stored in BOOT0/1 ) does not match the version of the second boot stage ( pkg2 , stored in the system NAND or emuMMC). This happens during failed or incomplete firmware updates.
Before modifying any internal system partitions, make sure your external bootloader assets can support your current firmware version.
: Ensure you are pushing the most recent hekate_ctcaer_x.x.x.bin payload. If you use a physical injector, update the payload.bin file on the device itself. Try disabling and re-enabling emuMMC to see if
The proprietary, native operating system designed by Nintendo to run the Switch console.
The emuMMC partition became corrupted, often after an interrupted update.
Update your payload injection device or application with the new .bin file provided in the latest Hekate download. 2. Synchronize the Bootloader and Hardware Payloads Fix 2: Repair a pkg1 and pkg2 Firmware
The “pkg2 read failed failed to launch hos” error is rarely a sign of permanent hardware failure. In almost all cases, it is caused by , SD card issues , or payload mismatches . By systematically updating your custom firmware, verifying your SD card, and double-checking boot configurations, you can restore your Switch to full custom firmware functionality.
This is the ultimate fix. If you have a clean, full backup of your Switch's NAND (including rawnand.bin , BOOT0 , and BOOT1 ) that you made when you first hacked your console, this will bring your Switch back from virtual death.
