he, me after unlocking were get NO SIGNAL, so i reflashed my phone and its working again,
i think you should do the rest..

1. Go to DOWNLOAD SECTION and DOWNLOAD firmware for yours c510 from FIRMWARE folder..
2. Go to DOWNLOAD SECTION and DOWNLOAD custpack from CUSTOM FILES folder.
3. Downlaod A2 UPLOADER from forum.. and use it to reflash your phone.

BUT FIRST, try to UNLOCK your phone again with AERIX, make shure U R registered on Aerix home page, write your username and password to AERIX, sign in. Then just press UNLOCK and by holding 2+5 connect your phone. Then everythings shoud just get fine.

REMEMBER to use LATEST aerix version, that will not destroy yours bootrom/erom, it may cause fast battery drain, i have this issue and now just searching for free fixing tutorial..

good luck.
