[Q] Unable to SBF using Linux

view story

http://forum.xda-developers.com – Hi eveyone, I've been a lurker here for quite sometime...until now. I'm trying to use BionicRestorer.sh to flash my bionic back to 902 so I am able to receive the OTA update. My phone was rooted and failed to update everytime. After several factory resets and even unrooting it still would not update. I'm trying to use the above to flash back to 902. I've read every post and FAQ regarding Linux and SBF and all files are in the correct location when it comes time to use House of BIonic I get this message in terminal: ./utils/fastboot.linux: 3: Syntax error: "(" unexpected ./utils (HowTos)
