Crossflash Dell PERC H200 from ir to it-mode
The short answer
I slightly followed this guide:
The longer answer is. I followed the guide, this way, but did it a little different
The longer answer
Prepare a usb memory stick formatted to fat32 with two folders called P07 and P20
Step 1 download old firmware
1. Download this zip archive from dell and unzip it: https://downloads.dell.com/FOLDER02950081M/1/Y2R1T_9211_FW.zip?uid=f06bb69a-8c88-4a54-ac7b-ee8826244140&fn=Y2R1T_9211_FW.zip
2. Extract 6GBPSAS.FW from Y2R1T_9211_FW/Firmware/6GbpsSASHBA_07.03.06.00_A10
3. Extract 2118it.bin from FY2R1T_9211_FW/Firmware/9211-8i_P7/
4. Extract sas2flash.efi from Y2R1T_9211_FW/sas2flash/p05/efi/
5. Place the three extracted files in the P07 folder
Step 2 download current firmware
1. Extract 2118it.bin from Y2R1T_9211_FW/Firmware/9211-8i/P20/
2. Download this zip https://docs.broadcom.com/docs-and-downloads/host-bus-adapters/host-bus-adapters-common-files/sas_sata_6g_p20/Installer_P20_for_UEFI.zip
3. Extract sas2flash.efi from Installer_P20_for_UEFI/sas2flash_efi_ebc_rel/
4. Place this to extracted files in the P20 folder
Step 3 download uefi shell
1. Download an uefi shell: x86_64 UEFI SHELL I choosed version 1 as it worked for the person in the guide Direct download link
2. Extract Shell_Full.efi to the root of the memory stick. I had to rename it to Shellx64.efi to use it with my motherboard, asus P8H67_M_EVO. Check with you motherboard vendor to determine how to use efi-shell
Step 4 flashing
1. boot computer to efi shell
2. If not present with a list with devices, type map -b
2. On my computer the memory stick is called fs0 so I typed fs0: to change prompt to the memory stick
3. cd P07
4. sas2flash -listall will show the controller. If not, check if it is installed to a pci-e port
5. sas2flash.efi -c 0 -list will show controller details and take a note of the sas address number
6. sas2flash.efi -o -e 6 will erase the old firmware and boot rom
7. sas2flash.efi -o -f 6GBPSAS.FW writes the dell 6gbs firmware
8. sas2flash.efi -o -f 2118it.bin writes the P07 firmware
9. Then I rebooted
10. boot into efi again
11. cd P20
12. sas2flash.efi -o -f 2118it.bin writes the P20 firmware
Notes
Directly copied from the source, step number changed to fit my tutorial:
1. Step 6 showed “Erasing Flash Region” and then after a while “ERROR: Erase Flash Operation Failed!”. I simply proceeded and the error did not appear to affect anything.
2. Visit source to get screenshots vit the error messages
