cd sdcard
cd romtoolbox
cd recoveries
flash_image recovery recovery_whatever.img
reboot recovery

Hi, please read this thread carefully:
http://forum.xda-developers.com/showthread.php?t=1473781
It works I have tried it myself several times.
Additionally I had to activate the download mode of the phone manually.
---> with stock recovery, remove battery, Press power + Vol- ,
plug in USB.

You flashed wrong custom ROM or wrong firmware? If you flashed I9070P firmware on I9070 phone - your phone is hardbricked. Maybe something like this can help you: http://forum.xda-developers.com/showthread.php?t=2701363
P.S. Now I see that on that link is question, not a guide...
Anyway tell what exactly did you do.

And if you can not enter in DM, then you may consider to donate your phone to devs for experiments.

Installing custom ROM from recovery shouldn't touch part where are part with Download mode. Try to pull out battery and retry. What happen when you try to charge the phone?
Tried many times to enter download and recovery mode..switched battery out and in...but it just boot normally and stuck on bootlogo...charging is not a problem...it charges normally...with a charging animation....
