Default now on 4.1 JB, well was...

Hi all, I flashed my versus 7" with the latest china JellyBean software F1-4.1.1-20130110.2.0.3-A721_V4.2.img, went fine but root broken, so recovered root with superoneclick, and all good, entered my google acct. loaded progs, checked mail, set options as I like etc, installed superuserelite and busyboxpro, rootcheckerpro, and all good, then a couple of reboots later It started up with the orig. std. 4.1 JB install with no acct., progs, optinos set, time zone etc. all gone! and its back to 'as first loaded 4.1' ??? ARRGH , the wasted time. I would really appreciate anyone who can enlighten me were I went wrong, is my 'customised' o/s gone? can I recover it as it was? or do I have to start again? Importantly how to prevent it reverting again and make it stick if I do? Please do help if you can.
Regards
