Today I tried again with firmware 007 and after there was an error message for the first time I started the flash again straight away and lo and behold, it worked and I'm now on FW 007. You don't have to understand why it is 10x not working and then suddenly it works. I really didn't do anything different at the time ...
well.. after trying this on V7, i was able to unbrick my XL2720Z.. !!

Thank you for posting this! I was on the verge of buying a 2nd one to replace this one.. I can confirm from being on V2 and now on V7 that the AMA Low tweak does work! It's glorious
