877 dead after ADSL firmware upgrade?

According to readme at ftp://ftp.cisco.com/pub/access/800/Firmware_Download_Readme_3_0_10.doc

the  firmware at ftp://ftp.cisco.com/pub/access/800/adsl_alc_20190_3.0.10.bin is for fixing dropped ADSL connections in 877.

I've  downloaded the firmware, renamed it to adsl_alc_20190.bin and used

copy http:  flash:

to  d/l it from one of my machines with Apache on the LAN into the router.

dir  showed that adsl_alc_20190.bin was the only file in the file system.

Then I  restarted the router with power button and it does not come back up  anymore.

The OK light comes on, then all lights flash once, twice,  third time and then only OK light stays on.

I can no longer ssh into the  router as 10.10.10.1 is unreachable. Resetting to factory settings does  not work in a sense that router does not react to depressing the reset  button even after 35 seconds.

Tried to start the router w/o flash module -  same thing.

What  have I done wrong and how to restore the router operation?

Thanks for all invaluable help I received.

Perhaps at least someone would be able to tell me what commands would show which version of firmware is used - built into IOS or uploaded onto flash?

sh dsl int atm0

will show you, amongst many other things, what ADSL firmware version is loaded and whether it is embedded or an external file.

Thanks, at least some questions get answered.

As no one helped me here, I won't tell you how I restored router operation.
