Wait, u tried to fix a 0001-power failure with a oven reflow? a 0001 is usually always the mosfets or the PSU. Rarely has it been reflow the xbox, and if u do, never use rubbing alcohol, kester 951 is cheap and should be the no-clean flux u use, if u don't have any with u, don't reflow it yet until u do. As if u reflow it without it, its likely going to break again.
Here info about your error.
http://xbox-experts.com/errorcode/E01/0001/I recommend you test all of the MOSFETs first before attempting to do anything if it even has a chance of rebooting again.
And did u test the PSU on a different xbox? to make sure it works fine?
I haven't tested my PSU on my other xbox. it was made in december 2009 and this broken one was made in feburary 2008 so will it work and not hurt my working xbox? I'll check the mosfets to. Im not sure if its exactly 0001 because it goes 000000 like 6 or 7 zeros then a 1
