If you've tried everything else, I suggest you take it to Service Centre near you. Looks like that fall is to be blamed.
P.S. Please post device related issues in their specific forums. That way you will get faster and better answers! :good:

I think you've lost your IMEI! here is a guide for recovering it. If you didn't root your phone to void your warranty, it's better to take it to a service center then.

im out of warranty and i took it to service center but they tried without success Due to baseband and imei unknown problem,the guy told me that it is software he flashed it several times but it didn't work,so i have to take it back,i will try the link and give u feed back,thanks for your help

i tried that link but unfortunately it didnt work may be is because i didnt have backup of esf files i missed some of the files like .nv_data i only have nv_data.bak,

So, your SIM card lost contact when the phone hit the floor and then instead of trying to remove the SIM card and put it back in you went and flashed the phone to solve the problem and that resulted in loosing IMEI number?
The Custom Rom you installed didn't make backup of your EFS folder?

yes exactly when the phone hit the floor and then instead of trying to remove the SIM card and put it back in i went and flashed the phone to solve the problem and that resulted in loosing IMEI number, but before i flashed it i made a backup of my rom using twrp but after this crash i restore my rom using the same twrp but my phone hang on booting,i was using ApoloJb_4.8_Extremev2_twrp kernel

the phone is acting very strength now,i found out even when i installed stock rom, my files are still on the phone,i used odin flashed it,please can any one provide link for me on how to fresh install stock rom and clear everything on the phone

How to install stock rom ? Search. This has been covered here thousands of times over the past two years, I'm not about to regurgitate it because you can't be bothered searching. Get a stock rom for your carrier/country from Samfirmware, then read the guides/tutorials stickied near the top of the General section.
If you want this fixed it's going to take a bit off effort on your part, we can't do everything for you.

Have you
1) Try another SIM card?
2) Look at the mobile network setting? Look for any abnormal setting? can search the mobile provider etc?
3) Try to flash another modem driver?

Hi, to add on, maybe you should tried again flashing with different modem/radio. The different ROM that you flashed may be using the same modem/radio and they may not work on your phone.
http://forum.xda-developers.com/showthread.php?t=1131950
This link seems to have mentioned various modem/radio for S2. You may want to try it. You may want to refer to another working S2 and check out what is the working modem/radio working well in your area. Then you flash in the same radio/modem.
If this still does work, it may be really the dropping of your phone has kill some physical part of your phone?

still don't work? strange!
just now i experienced the similar issue like yours, no signal bar. this happen after my phone become no respond to any key press. i have to hard power up through long press. when it power up i then see that there is no signal.
so i quickly go to recovery and flash a Modem/radio that i downloaded earlier.
after flash and it booted with good signal.
but my cause of issue i believe is kernel related as i just flash a dorimanx kernel yesterday.
