Hi there
I don't know it's right place for this question or not sorry anyway
I have Arnova 7bg2 Tablet and tried to add cwm to my stock image rom I downloaded from it's site and it was my first attempt for that.
everything was good and I unpacked it with RK29xxImageTools_v2.1. added some apps which I needed.
but in adding of recovery I think I made mistake.
replaced default recovery image with my own recovery I downloaded from "androtab.info/clockworkmod/rockchip/rk2918/"
and replaced misc image with another one that was on this downloaded zip file 
device started not bad but there were some problems in boot loading like didn't show boot image.
I decided to change rom by default one and I put stock rom on root folder for usual updating and changing.
device went to recovery mode but it don't work
E:Can't find misc
E:Cant mount /cache/recovery/command
.... and so on
tablet never get out from this mode (just restarting to this mode again)
I can't do anything
other flash tools like Rockchip batch tool didn't work
and by hard keys I couldn't change to flash mode
is there any software for changing to flash mode without hard keys way?
what should I do?
I'll say very really TNX to everybody who can help me
