Here are the nvflash versions for the .27 update. For those that wanna go back to stock for warrenty or have a dual boot this can come in handy.
I've tested the WW version on my on transformer and it worked (got a B70 with SBK1) created the US and TW version the same way with the same con-fig files so it should work! LET ME KNOW IF IT WORKS FOR YOU
But remember I'm not responsible for any bricks flashing my causes and you do this on your own risk.
1. Connect cable to computer and turn device on while holding down Volume Up. Screen will stay off, but USB will come on.
2. Find “APX” device in Device manager and update driver, then point it at usbpcdriver directory from the zip.
3. Run download.bat.
I'm hosting them on my own website with a 1gbit connection:

PS: these are a bit late i know been very busy! but perhaps somebody can benefit from these! Older versions still are available on the site itself
