Weird problem - just for your info (be aware)
Hi! Just to share what happened to me recently.
My Legend is now sent to service. Don't know exactly what went wrong, but anyways.. I rooted it a couple of weeks ago. Been installing and trying out some ROMs ju find "the one" for me (I'm not new to this, been using rooted Magic and Hero earlier). Finally, I installed a ROM with busybox..so far so good. Then I rebooted my phone - FAIL! It didn't wake up again!
Finally I managed to reinstall a ROM by running "step1" from unlockr's "how to root a legend"-Guide.. But the phone complained about me removing the SD-card. Figured, maybe it was because of unlockr's (Pauls??) testimage, so i ran the official RUU 1.31 and it installed fine (it didn't before). But no, sd-card was still "removed". tried a secont sd-card, same problem. Bought a new 16GB Class 10 card (previous cards were 2GB/8GB class 4) - No go. So - the conclusion is - my sd-card reader is gone. Not to worry, warranty will take care of it - but has this happened to others? If it has, maybe busybox isn't such a great idea on the legend for now.
