Firmware Updates for S Series Switches

I used the manual update process to upgrade the ONIE updater by rebooting & going into ONIE, then installing from USB:

Select - Boot into ONIE and select ONIE UPDATE - UPDATE ONIE
Type : onie-discovery-stop to have the prompt #

- mkdir /media (to create a folder for mounting USB stick)
- fdisk -l (to see the partition you have to mount from the stick) - (in this case sdb1)
- mount /dev/sdb1 /media
- ls -l (to see files are available, easy then to copy the file name)
- cd .. (to get back to root)

- onie-self-update media/onie-updater-x86_64-dellemc_s4100_c2338-r0.3.33.1.1-9

I then upgraded the switch firmware from within OS10.  It seemed a more straightforward process rather than attempting this from within ONIE.  I used the following commands:

#image install usb://onie-firmware-x86_64-dellemc_s4100_c2338-r0.3.33.5.1-23.bin

#show image firmware

then reloaded the switch to start the firmware update process.

The only issue experienced was I accidentally went into the ONIE Image Install section at one point & had to reboot & hit F2 to get out of a reboot loop which went straight back into onto ONIE Image Install.  

Why are these files still so difficult to locate? I have a requirement for an S5224F-ON, all the documentation tells me to simply enter the service tag, which makes sense, but all I get is a PDF about ONIE. 

Hello. The OS10 firmware files is available in DDL(dell digital locker) and ONIE updater/onie-firmware/PCIE files located here 

https://dell.to/3Yx0GiT.

There are two methods of installation as below:

ONIE method installation ( this is clean installation method, but deletes everything from switch and creates new partition on the switch and install OS10 firmware)
CLI OS10 upgrade ( this method is useful when wanting to upgrade from lower version to latest version which will not delete anything (startup-configuration) in the switch when upgrade the switch.
You can choose whichever that will suit your needs.
