Info 2 [Q] not able to open recovery mode

I wanted to install clock work mod on my phone,
I first. Downloaded mobile uncle tools from play store,
then flashed it using the app, I came to know that the clock work mode installed was not suitable for my phone,
now my phone doesn't detect the sim card,
and even skips recovery mode and boots normally,
I tried many times to open recovery mode but it doesn't, it skips,
I tried reflashing with correct one but it doesnt show any difference
How to fix this problem? Help me pls
,the phone is celkon ar40(local indian manufacturer) with Chipset of mt6572...
