How to Unlock WD SMR HDDs Firmware Area without Firmware Unlock PCB

,

It is now possible for DFL users to unlock the WD SMR HDDs firmware area on the original PCB without special firmware unlock PCBs.

The new solution for WD SMR HDD firmware unlock is available within DFL-WD hdd repair tool and to use this solution, users need to have DFL HDD ROM chip pin reader(Many users have already had this one.) and the steps are as below:

1, Remove the original PCB from data drive;
2, Read the original ROM from original PCB by the HDD rom chip pin reader set without soldering rom chip off;
3, Generate firmware unlock ROM;
4, Write unlock rom to original PCB by the HDD rom chip pin reader set without soldering rom chip off;
5, Install the original PCB to data drive and users can see the firmware area is already unlocked successfully;
6, Users can use DFL-WD hdd repair tool to backup important firmware modules, specially the module 190, smrzone, T2data, etc;
7, Users can image the HDD or extract lost data directly if users have DFL-URE or DFL-UREP by using DFL latest T2 auto loading tech;
8, If the original PCB is physically damagaed but the Main chip and ROM chip are still good, users can use the special firmware unlock PCB and then move the original main chip to the firmware unlock SATA PCB and write original ROM to the firmware unlock PCB for disk imaging or file extraction;
9, In some cases, users need to repair the damaged firmware module 190 or repair the SMR HDD slow issue to continue for data recovery.

The WD SMR HDD firmware repair and data recovery solution is more and more complete and successful and DFL users will be able to fix more and more new data recovery cases.

Please note: the new solution supports 800066, 67, 69, 77, 11, etc but doesn’t support 810033 and 810035 which have quite different rom structure and algorithms. For WD 810033 and 810035, users still need to get the special firmware unlock PCBs for firmware unlock.
