Cisco Router 841 is in continuous loop of the following:-
Readonly ROMMON initialized
PASSWORD RECOVERY FUNCTIONALITY IS DISABLED
loadprog: bad file magic number: 0x0
boot: cannot load "flash:"
System Bootstrap, Version 15.5(1r)T1, RELEASE SOFTWARE (fc1)

I do not get even a ROMMON prompt , where I could run some command and bring it back to life.
How to stop this loop and resolve the booting issue?
Agreed but how to stop the looping message?
I do not get a prompt .
Answer my question first: Where did this router come from and who configured "no service-password recovery"?
Client Team configured that.
Contact the client team and tell them to replace the router with something that works.
The reason is because forcing the "password recovery" into a router, with password-recovery disabled, will mean the config of the router will be deleted.
Do you have the config of the router?
That's not an issue. I need to stop this loop and work on it.
Then read my responses very carefully.
There are two things wrong and causing the router to go into a crash-boot-loop. They are:
1. Someone has mis-configured the boot variable string.
2. Someone "smart" (for lack of a better word) has configured "no service password-recovery".
Had #2 not been done, stopping the router crash-boot-loop would be relatively elementary.
So here's the solution:
1. Look at the back of the router.
2. Near the WAN ports, is there a tiny "Reset" button?
IMPORTANT: The Reset button plus the presence of "no service password-recovery" command means the router will erase the config.
I tried resetting the device once.
I wish to know method to reset the device.

seems like a flash issue.
No, it is not.
Someone mis-configured the boot variable string and then "locked themselves out" by using the command "no service password-recovery".
