Hi, I throw away Angstrom and moved to Gentoo after a few updates complete scrambled Angstrom... Consider to boot from SDcard, because it can be "edited" via an USB cardreader on the PC and can be replaced if weared out (flash has a limited count of write cycles). If the internal flash is damaged, you a solder iron, VERY good eyes and a very very steady hand....
