[liverpool211]

Hi all.

How can i fix this JVM Error 547 flash write failed

I have tryed JL_Cmder with no luck just got

Connecting to device...debug: Port closed
Error: unable to connect to device

Then made a .cmd file
cd C:\Program Files\JL_Cmder
javaloader.exe wipe -usb
pause
cd C:\Program Files\JL_Cmder
javaloader.exe wipe -usb
pause

then taken out battery then put battery in same with USB cable clicked the wipe.cmd file i made then i got
connecting.....
connecting.....error debug error port.

I did download the software from RIM websites for O2-UK and it works great and install fine BUT im still getting the JVM Error 547 flash write failed

I downloaded the latest desktop manager, still no sucess

My device dont have a password on it, Just comes up saying...

no device detected, push ok to continue

However

desktop manager detects the phone with my BB Pin then i click update. Im still stuck to reconnect

comes on with JVM Error 547 flash write failed i can still scroll with diffent options on the mobile/cells screen



Question is why is desktop manager detecting my bb pin and my not delecting it on JL_Cmder on
