Switch Dell S4048-ON - EFI SHELL
We have a Switch model S4048-ON that after an attempt to update the Firmware the equipment does not
can no longer boot the system. From a console cable connection it is possible to see the following
screen:
In some forums we found other users with similar problems, who managed to solve
the problem changing the boot priority order in the BIOS menu, but on our equipment there are the following options:
In the screen above we try to select other boot options and disable the other boot priority orders
We would like a method to restore the functioning of the system, as this is a
equipment that will have great importance in our network topology. Furthermore, the guarantee
support period for our equipment expired in March 2023 so we were unable to contact support

@DELL-Charles R
A bootable pendrive was made using the Linux dd feature and throwing the ISO image "onie-recovery-x86_64-dell_s4000_c2338-r0.3.21.1.0-6.iso" onto the pendrive using the following command syntax:
sudo dd if=/{path-to-iso} of=/dev/sd{x} bs=1M status=progress
After booting the switch on the pendrive, the system was restored and then changed the boot option to start with the switch flash.
The SERT team is very grateful for your support!!

@DELL-Chris H Thanks for the answer.
But I haven't no way to test this alternative because the equipment does not start GRUB so I can't choose the "ONIE Rescue" option. Here is a video of the output via console when the equipment is turned on:
The options <del> or <F2> are to enter BIOS setup

If that is the case I'm not sure if it is going to be recoverable then.

@DELL-Chris H , In this case, taking into account that our warranty has expired, can you contact me for support technician ? As this is a highly specialized piece of equipment, if applicable we can negotiate a technical visit from Dell support for an assessment.
I would greatly appreciate it if you could provide us with contact with technical support in the region.

@tomfinn
Good morning Tomfin, thank you for trying to help.
I tried both approaches suggested by you but still without success.
In the first approach when accessing the fs0 directory: I can't execute the .bin
In the second approach, the "bcfg" command is not recognized by the shell.
The same attempt was made for fs1: and fs2 too.

Hello
1 Create ONIE recovery bootable usb drive using ONIE recovery iso image which can be downloaded from the support site.
2 Once ONIE is recovered on switch, then you can update ONIE-FTOS-filename.bin via ONIe mode.
To create usb onie recovery usb drive, need to download RUFUS tool from google search and install on laptop and create recovery usb.

Hope this helps.

@DELL-Young E Thanks for the suggestion, the recovery procedure worked successfully, it is now possible to access the ONIE grub, however in an attempt to install the new operating system I receive the following output in the printout below.
I reinforce that the switch communicates normally with the tftp server and even seems to complete the download of the image, but the installation fails, I tested V9.14.1.14 and V9.14.2.23

Hello, I see image format failure - Please install the firmware though USB drive:
USB drive filesystem should be FAT32.
to mount the usb drive in ONIE mode, see below:
#mkdir /mnt/usb
#fdisk -l
#mount -t vfat /dev/sdb1 /mnt/usb
#cd /mnt/usb/
#/mnt/usb/ls
#/mnt/usb/onie-nos-install ONIE-FTOS-SK-9.14.1.14.bin

@DELL-Young E As suggested, I created a pendrive this time with the FAT32 file system and put the OS "ONIE-FTOS-SK-9.14.2.23.bin" on it and then using ONIE mode I passed the contents of the pendrive to the Switch's flash
and then I tried to run it using onie-nos-install. But I get the same error as before:

Hello,
The text in the image is hard to read. You might upload an image that has the text more clear.
It looks like it says: invalid ONIE update image format
Could you try download again to make sure you got a good image and try again?
