How to recover ALOM Main Flash (ReFlash EPROM) ? -- ALOM stuck in a loop

Question

Hello,
I had an issue while flashing the ALOM Main Flash of a Sun Fire v210.
Now the ALOM boot is stuck in a loop trying to load the main ALOM image.
As a result the ALOM Main Flash is broken but I can still access the
ALOM Boot Menu. I can also boot Solaris with the Jumper on FP2 or FP3
but it does not recognize the SC anymore.
Is there a way to recover it from Solaris and/or using the
"f - Wait for flash download from host" from ALOM boot menu ?

Anybody knows if the source code of scadm tool is available somewhere ? (opensolaris etc. ?)
I don't have any additional advice to offer other than asking that you to try the flash-update all over again,
one more time, as if it were the beginning again.Yes but how because the SC is not discovered anymore by Solaris :
"rmclomv: WARNING: DP_GET_SDP_VERSION failed, ret=4"
"The SC hardware could not be initialized."
Can you try to flash the mainalomfw ? Your log contained only the flash of the alombootfw !
/usr/platform/`uname -i`/sbin/scadm download alommainfw
I guess jumper JP2 allows to recover from a failed flash by selecting the un-touched half the PROM.It does not work as the SC is not responding anymore to Solaris

It's a pitty that obtaining OBP/ALOM updates requires a service contract. I got a V210 recently.
Unfortunately both OBP and ALOM are the intial release 4.8.2 / 1.0.I agree but it's probably also because you need support in case it fails ;-)
Thanks for your answers!
