Upgrade QNX 6.2 bootable CF to bootable QNX 6.5 without formatting

How to update boot loader on the CF card formatted and bootable under QNX 6.2 to QNX 6.5. I need to update boot loader 
only since 6.2 bootloader does not work with 6.5 .boot image. The flash card can not be re-formatted. I was attempting 
to run 6.5 dloader under QNX 6.2 with added libc.so.3 library and new pc2 file but I am getting not resolved symbols 
error :

unknown symbol: __deregister_frame_info
unknown symbol: _Jv_RegisterClasses
unknown symbol: __register_frame_info
unknown symbol: __deregister_frame_info
unknown symbol: __register_frame_info

Any helpful solution or suggestion are really appreciate.
Janusz

Janusz,

Those symbols require the new 6.5.0 libc.so.3, so you will need to make a new QNX boot image with 6.5.0 libraries before
 you can run the utility.  You might have success if you set LD_PRELOAD=<path of 6.5 libc.so.3>.

I did copy QNX 6.5 c library together with dloader from QNX 6.5. Yes, it works under QNX 6.5. The point is to upgrade 
the loader to 6.5 version when the 6.2 is still running.

Then you will need a dloader program that has been re-compiled to run under 6.2.0.  Those errors are because the libc.so
.3 will not be used until after you build it into a new IFS, which will require putting a 6.5.0 bootimage onto the 
device.  The LD_PRELOAD environment variable  is an attempt to make the load still try the new libc.so.3, even though 
the 6.2.0 libc.so.3 is already loaded from /proc/boot.

Is it possible to get a dloader source code ?
