Hash Sum mismatch

[Iklax]

Hi guys , this is my first time jailbreaking my phone and i followed a youtuber named "everythingapplepro"'s untethered ios 9 jailbreak tutorial and everyth was going smoothly until i went into the cydia app and when cydia was preparing filesystem it took less than a min and my phone restarted , according to everythingapplepro it usually takes about 10-15 mins and so i went back into the cydia app and when i refresh i keep getting this "failed to fetch " "Http://apt.modmyi.com/dists/stable/main/binary-iphoneos-arm/Packages.bz2Hash Sum mismatch" message . Can some one please please tell me what to do? Please respond! Thank you !
