I own a Blackberry Bold 9790 under one year now. Yesterday the phone went dead with just the red light flashing. I am being told that the Firmware has crashed and that has been happening with this model of phone. Is there anything which I can do to restore the phone?

Hi and Welcome to the Community!
I have no way to validate the diagnosis you received...it could be causal, or it might not be...from what you state, there is insufficient information from which to diagnose at an internet-distance.
But, please try this sequence...note that, throughout the entire 4h15m process, your BB must remain directly connected to a known-good wall charger (not PC USB, not a cradle):
This has been known to "kick start" some BBs.
It is also possible that your battery or BB has experienced a problem...to test, this sequence is needed:
The results of this will indicate if it's your BB or your battery that has the problem. Note carefully please that "new" and "know good" are not necessarily the same things. While rare, a "new" battery certainly could be defective. Rather, the simplest (and least costly, btw) method to conduct this test is to find someone with an identical BB who has no issues...trade batteries and see what happens.
If your BB indeed results as being causal to your issue (by virtue of the battery swap test), then it may be that the diagnosis you received is correct. And there are methods to attempt to recover it, if it can power up to a sufficient state (the flashing red light indicates that it indeed can do so).
The simplest way is to, on a PC (you cannot do this on MAC):
1) Make sure you have a current and complete backup of your BB...you can find complete instructions via the link in my auto-sig below.
2) Uninstall, from your PC, any BB OS packages
3) Make sure you have the BB Desktop Software already installed
4) Download and install, to your PC, the BB OS package you desire:
5) Delete, on your PC, all copies of VENDOR.XML...there will be at least one, and perhaps 2, and they will be located in or similarly to (it changes based on your Windows version) these folders:
6a) For changing your installed BB OS level (upgrade or downgrade), you can launch the Desktop Software and connect your BB...the software should offer you the OS package you installed to your PC.
6b) Or, for reloading your currently installed BB OS level as well as for changing it, bypass the Desktop Software and use LOADER.EXE directly, by proceeding to step 2 in this process:
If, during the processes of 6a or 6b, your BB presents a "507" error, simply unplug the USB cord from the BB and re-insert it...don't do anything else...this should allow the install to continue.
You may also want to investigate the use of BBSAK (bbsak.org) to perform the wipe it is capable of.
You may also want to try the "Bare Bones OS Reload Procedure" to attempt to narrow down the precise causal item:
When the behavior presents, you know the culprit...the last thing you loaded.
If the behavior does not re-present, then you know that either step 1 or 2 cured it.
If the behavior presents no matter what, then you likely have a hardware level issue for which no amount of OS or software can cure.
You may also need the use of these tricks:
If you are on MAC, you are limited to only your carriers sanctioned OS packages...but can still use any levels that they currently sanction. See this procedure:
Good luck and let us know!
