Root and Memory problem

So... I bought an MT6575 processor phone...And tried to root it with MTK Droid Tools and SP tool... I read some instructions and flashed the memory (on the recovery writeback process,where the rom length was asked, I used the hex number found for the RECOVERY value on the scatter file I got).

I quietly messed up with the whole rooting thing and never was able to finish it (couldn't find how to enter cmw mode).

So... The phone is still working but it says that it doesn't have enough free space. It doesn't seem to be very important, but it still give a lot of notifications. It says that 123 mbs of the rom are used and only 4 are free and I have to delete some applications.. However I am not able to..Since the rom is still unrooted...

Can someone please help me with this? What shall I do? Flash the rom once again? But what hex value should I use??
The problem is all about the length of the rom I changed..Isn;t it?
I would be really grateful if someone could help me with this... I've been breaking my head about a week now... So could you please please kindly let me know what is wrong and how to fix it?
Thank you in advance!

Hello and thank you very much for your interest! I am glad someone responded!!
So, it seems like the rom problem just fixed itself. I repeated the rooting steps and the space error is gone.
As for the cwm mode... I am able to get the phone to the adnroid recovery mode (by pressing the power + vol buttons) but not to the cwm mode... Is there something I had to download to my phone in order to be able to?
Sorry if I sound like a complete noob (actually I have to admit I am!).

Thank you again for answering!

Thank you very very very much! I'll give the quick boot thing a try later today!
Anyway. thank you a lot for your interest and your quick replies!
I suppose that this topic can be closed now since you answered all my problems!
Thank you!!
