The hex file is the binary file needed to manually update the firmware. Make sure you have the H100i RGB Pro XT model as other variations are not compatible with the firmware uploaded in the first post.

The logs do not have a URL so you'd have to use something like WireShark and hope there is no authentication and it doesn't use HTTPS to fetch the binary file. Or you might never find out what the URL is.

I actually found the firmware in C:\Users\your_user_folder\AppData\Local\Temp It would stay there indefinitely until some program or Windows clears Temp. It does suck how the iCue software itself will make the AIO go into an error state if upgrading failed. At least for me the firmware wasn't actually corrupted as powering off and releasing all stored power reset the AIO and it booted with original firmware.

Since there is a bunch of posts and replies of people asking for H100i RGB Pro XT firmware file... I uploaded the one I used to manually upgrade to latest firmware. https://www.mediafire.com/file/7bz9kf3fhtujffb/CUEGxaulj%257Bd666be6f-b520-490c-92cc-8f9e2442d0cc%257D_temp_H100I_Pro_XT_V1.1.32.hex/file The method to manually flash the firmware is in this video provided by Corsair: [ame] [/ame] If the above fails, try turning off your computer and shutting down the power supply and drain the remaining energy and try again (it didn't work for me after the iCue failed update till I shutdown, turned off PSU and drained all the energy). This caused the H100i to function correctly on older firmware and was able to update right away. If it still fails, try doing the manual flashing process in Windows 10 Safe mode.
