Hi folks,
Having an issue here with a brand new 3650.
When being deployed along with other 4 units there was a power blackout at the rack and since then this one will not load IOS up and remain in the boot loader.
The thing is it seems to be stuck in there even after following all the steps out there to get around this.
* Booting from the resident IOS results in one of the packages not found, but it's actually sitting right there in the flash:
* Booting from a USB flash results in a Signature Verification Failed.
* Doing an emergency install from a USB flash results in a Failed to process provisioning file.
Find attached all these and other details, perhaps you guys have a clue on how to get a good IOS in (hope it's not a faulty flash).
Thanks all

You need to do below steps :
switch: set BOOT usbflash0:cat3k_caa-universalk9.SPA.xxxx.bin
switch: reset
Are you sure you want to reset the system (y/n)?y
System resetting...
post reset you can see the device is coming up in Bundle mode --> 'sh ver' can help you to know the mode
it is recc to keep in install mode.
Steps:
remove the usb and clean the unwanted files :
req platform software package clean switch all file flash:
insert the usb again and copy the image from usb to flash
convert the image to install mode:
req platform software package expand switch all file flash:cat3k_caa-universalk9.SPA.xxxx.bin
sh boot to verify the current boot order and change boot order to packages.conf
conf t
boot system flash:packages.conf
wr mem
reload
post reload again clean the unwanted files.
req platform software package clean switch all file flash:
<<note this will remove the .bin ios file too, that is not required for the device further>>
>>>>>>>>>>>>>>
The command req platform..... commands and install commands both works in latest ios, refer release notes.
if req platform commands is working please proceed. rest all other steps remains same.

My Catalyst 3560 abruptly shut down, and I was unable to boot it up despite my best efforts. I then connect the console using Tera Term rather than putty, unplug the power cable, and then put it back (I did this five to ten times on/off), and when I press enter on Tera Term, I receive a prompt. I know it is silly solution but I have more for you too
-------------------------------------
hold and release MODE button while you power it on
switch: flash_init
switch: load_helper
switch: Dir Flash:
switch: rename flash:config.text flash:config.old
switch: boot
-------------------------------------------------------------------------------------------------
if switch didn't boot properly, then you need to reset the switch but you will loose all the DATA, to proceed please follow below steps:
Step 1.
Connect up your console cable and power on the switch, whilst holding down the “mode” button:
Initialize the flash file system with the command: flash_init
Step 3.
Delete the config.text file from the flash directory:
switch: del flash:config.text
Are you sure you want to delete "flash:config.text" (y/n)?y
File "flash:config.text" deleted
Delete the vlan.dat file from the flash directory:
switch: del flash:vlan.dat
Are you sure you want to delete "vlan.dat" (y/n)?y
File "flash:vlan.dat" deleted
Reboot the switch and you’re done:
switch: boot
