ORANG001 Firmware 3.33.61.9

I'm returning to stock from HTC_001 , my CID is ORANG001 (UK EE) , I cannot find 3.33.61.9 firmware only file as I want to restore my TWRP backup and then take the 4.19.61.2 OTA , I do however have the OTA_M8_UL_K444_SENSE60_MR_Orange_UK_3.33.61.9-2.26.61.1 file , can I remove the firmware.zip from here and flash this via RUU fastboot ? .

Regards
Mark
