kindly help urgently..htc desire/bravo stuck at bootloader screen

hi frends..
i have searched on google for almost 2 days for my problem..bt didnt found anything thats why posting this thread

actually my problem is while flashing new rom on my bravo i get stucked at bootloader screen..
n the main problem is my both volume keys i.e volume up & volume down are not working at all..
thats why i am not able to go into recovery mode

so kindly give me some suggestions about "how to go into recovery mode without using volume keys" n while m stucked at bootloader screen

also i formatted system..so there is no hope of going back..as practically my phone is without any rom

also i tried using ADB but its showing an error of device not found.
i also tried using PB99IMG.zip method..but in dis also we need volume up key for saying "yes"
n as already said my both volume keys are not working

so kindly help me considering me as a noob
sorry for bad English
n as m not having much info as u guys about all these things..kindly consider my mistakes

my device is rooted
s-off

thnx
