Any help out there Please

I got myself the AZ premium Plus - Its a clone from China - I know I know ur gonna say its my own fault but anyway when trying to upgrade to enigma2 it froze and is now stuck in the "booting" mode - i bought the lead and tried the advice in the tutorial but i get as far as connecting and i am getting the:

xosPe0 serial#afb47efe68cceef4f95c03f6bf 65836f subid 0x50
xenv cs2 failed
xenv cs3 failed¡øpower supply: ok
dram0 ok (8)
zboot (1) failed

which means that procedure will not work

I have now contacted them saying that it was stuck from day 1 and see if they will take it back and refund or replace - but i doubt they will
so what i am asking is - is there anything i can do to get it going again? i like the spec of the box and really dont want my 230 usd to be down the drain - i will try anything - even if you know of someone on another site who may be able to help - i'd be grateful if you could point me in his/her direction

your advice is very much appreciated

thanks
