initramfs - RX-HDX Image Recovery

            Method to recover from RX-HDX image corruption

            Revision date: February 27, 2019

            Description:

            In some rare cases, certain RX-HDX software component(s) may become corrupted and resulted in the device not being able to boot up properly.

            The customer should try to perform a factory setting reset  to determine if the issue can be resolved.

            If the issue still cannot be resolved with the factory setting reset, the following procedures outline a recovery method which can be conducted by the customer to attempt to recover the device firmware image.

            Procedures:


            1. Get a USB stick

            2. Download
            https://s3-us-west-1.amazonaws.com/ncomputing-citrix/workspacehub/repair-pi
            and save it on the USB stick

            (Doing so, check the file size of 959259 bytes, approx. 1 MB, and the MD5
            sum of cff7ac47c014e4336f7adb6c59ea45da)

            3. Get a normal firmware update LFI image (need to be firmware 2.40.4548 or later) and also put it on the USB stick

            Here is the latest RX-HDX pre-release firmware (2.40.4548) as of February 27, 2019

            https://s3-us-west-1.amazonaws.com/ncomputing-citrix/workspacehub/lnx-2.40.4548-NC-k414-armhf-190211.lfi

            4. Plug the USB stick into the defective device when it gives you this
            "(initramfs)" prompt (see screenshot below):




            5. Type each command below and hit Enter:


            mkdir x;

            mount /dev/sda1 x;

            chmod 755 x/repair-pi;

            x/repair-pi


            (Note: If the system is giving you errors, write
            /dev/sda instead of /dev/sda1 for windows-formatted USB sticks)

            6. Wait a few minutes until the system says "Everything should be good now"

            7. Press Ctrl-Alt-Del to reboot the device
