I have an android tablet, 7" (green light, no vib, black audio port, 30 pin connector, WMT2.0_88, no box) ... Pleeease help. This is driving me crazy...
Your model looks very simmilar to this one LY-706 MID Android tablet (WMS8060C)
Compare chips and if you find that is similar, maybe Y-706 MID Android tablet ROM will work. Look at http://androidtabletzone.the-talk.net/forum or http://wmt8505-tablet-zone.americantalk.net/forum or just google it.
I also bricked my tablet (different model than yours) with Slatedroid 1.7.4_base ROM.
Did you try a countermeasure (from this topic http://www.slatedroid.com/topic/18061-guide-install-wince-hopelessness-edition-on-flytouch/) for this problem -another ROM which maybe can repair your Android boot sector? Valid link (from topic above) for this ROM is http://dl.dropbox.com/u/6955629/script.rar . Maybe you will have a lucky with this repair ROM.
I'm now using Windows CE 6.0, it's better than nothing
