I do not know if it is now frowned upon or not recommended (I haven't been on forums for over a while), but flashing clean and not-modified v69 from wiki in boot mode via JMGarageFlasher (w/grounding pin) worked for me first try. Straight up downloaded v69 and flashed it with no modifications to the file.
After boot flash, I read flash back, in boot mode with ground pin, as well and confirmed that original v69 matched file that was read back. Then I applied EWS delete to v69 file (ews physically removed from the car), and flashed it with MS4x in regular full flash (not boot mode).
