[cisco-voip] Cisco 7975 or 7965 stuck at speaker button Red LED, sorry if this is a repost

There are 3 I can find documented internally.
1. Soft Reset (documented publicly)
2. Hard Reset (see below)
3. Hard Reset but keep network settings (Terry’s)

The hard reset is:
3491672850*# - the “nuke it from orbit” option which is a total format the flash, hard reset but does not preserve the network.

Prior to version 8.3.3 only the first 2 existed, but number 2 unintentionally kept the network preferences, acting like number 3 does today (see CSCsi60439).

And then there were three.

Wes, Ryan, Brian, how many are there really?

I have used the below to reset 79xx series phones and load a new firmware on them.  Setup a laptop with a TFTP server on it and on most I have been able to recover what looked like a bricked unit.

Thanks

#Total Hard Reset
The code for the total hard reset is: 3491672850*#
A total hard reset formats /flash0 blowing away everything except CNU.  All settings and personalization of the phone is removed.
#Hard Reset with Network Setting Preservation
The code for the network preservation hard reset is: *7412369#085
And it also does a complete format of /flash0 - yet it preserves the network settings so that after the format, any static IP and other network settings are preserved. The settings are stored in volatile RAM, so it is important to not remove power to the phone during this process
#Prerequisites
There are a number of prerequsites that are necessary for a successful factory reset.
1.            You must have a network environment in which DHCP is used to provide the phone with an IP address and a TFTP server (i.e. DHCP option 150).
2.            There must be an appropriate default load for your phone model on that TFTP server:
o             The default load name is: termxx.default.loads (where xx is part of the model number, 41 for 7941, 62 for 7962, 70 for 7970, etc.)
o             The version of the default load must be the same signing type (dev or release) as the phone on which you wish to do a factory reset.
o             This file (termxx.default.loads) is packaged with every phoneload that is installed on the callmanager, but since the name is not unique per phoneload version, the copy of termxx.default.loads is always the one from the most recent load that was installed on the callmanager. It may not be the type (dev or release) that you want.

HI Anthony,
Appreciated your reply,
The link you sent requires login,

I am not sure what version on them, since they are stand by units for a while,  from the last time they were working at one point.  I tried to reset, 1234567890*# but still the same issue.

Did you already look through the bug search tool?

https://bst.cloudapps.cisco.com/bugsearch/search?kw=stuck%20boot&pf=prdNm&pfVal=269065653&sb=anfr

What version of firmware is it, and what can you do to clear the problem?  I.e., Power cycle the phone?

Greeting to all,

Lately, I have some CP-7965 and CP-7975 stuck at speaker button during boot up as red LED and stay there for long time.  Has anyone got this issue and know how to fix it?
