First try a Battery pull reboot by removing the Battery while your device is Powered On , wait for a min then reinsert it back , please check if your device reboots. Or
Have you recently installed any application before this Problem started ? Think carefully !
If you have then try to boot your device on Safe Mode , On Safe Mode delete any application which you think might be responsible for this issue , from Options > Device > Application Manegement > locate and delete any newly installed 3rd party application , it might help in resolving your issue :

I too have the same problem with my BlackBerry 9900. When the "Loading Bar" comes on, the entire phone freezes when it reaches around 75 percent complete. I know my 9900 freezes because alt + right-shift + del doesn't work. I have even tried the "Safe Mode" trick with the escape button but the phone still freezes. Is there anything else that might help?
Welcome to BlackBerry Support Forums
If you're unable to boot your device on Safe Mode then as a next steps you should to reload the OS , but as you device is on a reboot loop it will not allow a simple reload , so refer to those Knowledge Base articles and try it :

I have a T-Mobile US BlackBerry Bold 9900 which uses a sim card. Will this updating process be effected if I have already discontinued my cell phone service? (I don't have a sim card anymore)
Yes you can try it , you may not recieve the most recent OS version because it all depends on our Carrier or wireless service provider. But if you can manage an active SIM it will be helpful . Try those methods if first fails then try the next one .

Try to contact nearest bb service center
Hi there ,
This BSCF is sponsored by BlackBerry itself so that user can exchange ideas with each other , If we advise users to visit there respective Carrier at the first Instance even without trying to offer any help then the purpose of this forums will be useless. If possible we should try to help as much as we can .
I hope you understand .
