Use the chinese update.zip
Its not bad... I had to use it because I was fooling around too much and crashed with no reboot in sight. I used SYSTEMAPP REMOVER to disable all the chinese apps and root explorer to delete the old files in /system/app then rebooted.
Also, you can add the marketplace through the /system/app just enable read/write and there is no need to push through ADB!!! it will give you error once, rewrite over the files again, re-install, and re-start and voila... you get the free games from the "GoMarketHD" and you get the MARKET back, granted, its not the HONEYCOMB market but hey, its the market... jejeje
