regret rooting my m8 (Barclays issue)

[xploitUK]

My HTC One M8 was rooted using an all in one toolkit and ive also used firewater to make it s-off

regret rooting now as my Barclays app wont work - anyone rooted and managed to get barclays app to work or found a way to unroot the m8?

been an iphone user for past year or two so a bit rusty on the flashing of roms etc - any help greatly appreciated
