Between Jan 2021 and Jun 2021, we use some KingFast SSD, which using PHISON S11 Chip and YANGTZE memory. Those SSD may going to write protection status, it’s origined from firmware bug in firmware version SBFQP1.3 and SBFQPW3, to solve this problem, we suggest user update firmware to SBFQP1C3.
This guide is applicable to the SSD that has already entered the write protected state, and cannot enter the windows system normally.
First, let’s prepare: 1. a Windows PC than can run normally; 2. an USB flash disk capacity no less than 8GB; 3. Firmware update tool “update S11 FW(PE)”—Download here.
1. Right click “Make_Usb_Device”, run as administrator, and select U disk(this step will delet all files in USB flash disk), select “Make” to confirm, when message “It’s been successful!” shows, file write in successful.
Now we go for next step: firmware update.
2. After login to PE system, right click “Computer” and find U disk, open U disk and open file “Reinitial&DLMC_SBFQP1C3_20210720”, then run program “Reinitial&DLMC_SBFQP1C3_20210720.exe”. 3. Follow software guide to go next and update, pls note: update firmware will delete all files within the SSD.
Select SSD within Device option, regularly it will auto detected; then click “ Get Device Info”, then “Upgrade Firmware” When message “ Update Successful to SBFQP1C3” shows, update finished, now there is nothing within the SSD, and the PC system need to reinstall before it can run normlly.
