New Issue on New WH14NS40 drives

[Brianebrown1979]

Hello, So I decided to purchase two new WH14NS40 drives and I am trying to flash them. They are brand new service NS50 manufactured in September 2020 drives. I am following the guides and have tried flashing HL-DT-ST-BD-RE_WH16NS60-1.03-NM00600-212005081010.bin and HL-DT-ST-BD-RE_WH14NS40-NS50-1.05-NM00900-212005061444.bin with no luck.

The shipped firmware is version 1.05.

I keep getting "CheckSum is mismatched. Drive will go to BOOT mode Please retry again."

Any suggestions on getting around this, I tried searching but nothing I am seeing is helping.

Thank you!

Before cross-flashing you should first flash the 1.05 for your drive with the "enc" option checked in SDFTool flasher.
If succesful you can then cross-flash whatever you want.

Saw a post by MartyMcNuts going to try his solution.

Both a good now, updated to HL-DT-ST-BD-RE_WH16NS60-1.03-NM00600-212005081010.bin

Thanks!
