Need Help on Updating my Ultra + 256GB SSD. Firmware update failed

i just try to manual update my SSD but it failed. any update on how to fix this issue?.

thank you

what sata mode do you have the computer set to? If it is IDE try switching to AHCI to update. Also what is the FW version on your ssd?

i use AHCI to update. Firmware Revision X2306RL.

maybe try moving the ssd to another system. if it also fails there contact sandisk support for a replacement 

still not updating. are you guys cannot fix this or what?
