Arrrrrgh! I've forgot to wrote that not long ago new versions of 24F1ST appeared which are now rebadged 224DB drives. I'm sorry that I haven't posted this info earlier.
IMPORTANT INFO for everyone - exact version of 24F1ST can be recognized by drive's bottom cover which should match 224BB OR 224DB - look at the location of the squared dent:
And here is the earlier 24F1ST version photo gallery - you can see that location of the squared dent is the same as on 224BB bottom cover:
And I've crossflashed few 24F1ST drives into 224BB by myself (all drives had manufactured date Jan 2013). Later drives (for example Jun 2013) are rebadged 224DB.
I appologize again for forgetting to post this important info.
marcus_667, is your drive totally bricked? MTKflash should help if the drive can't be recognized by samsung flasher...
