Having trouble with my Xperia J after I rooted and installed CWM. Since then the device doesn't boot. After pressing power button it shows a 'yellow' light and then nothing happens. I then flashed it using flashtool with twrp2.4.3-jlo's boot.img and used custom ROM 'MOD_For_Z-Fusion_For_CM10'. It installs fine but SIM card is not recognized. I read somewhere about this problem and the resolution was to install a correct firmware. How can I get my SIM card read? Do I need to flash the device with another firmware?
The bootloader is unlocked and if I ever install boot.img apart from twrp2.4.3-jlo's one then the installed CWM doesn't works. Only twrp2.4.3-jlo's own recovery mode works fine.
Another major problem is that if I press volume down button and connect with the USB cable then only the BLUE color appears and FLASHTOOL reads it in fast boot. So, I am never able to set it in flash boot.

Please help me in getting my device up and running. Let me know if there are some firmware or custom rom which I can Install and get my device running.

Thanks in advance :)
