£20 if you can help fix this today

[Guest JohnofArc]

I will paypal over £20 to someone's email account if you can explain it clear and unambiguous terms how I can get a 'bricked' hudl back to life again.
I have outlined the issue on this thread

Originally I rooted it and removed a variety of Tesco rubbish (I cannto recall what)
six months of perfect use follow.
Last week a routine clean-up with Android Assistant rendered it unusable.
I did a factory re-install and now it is stuck downloading 5.1 and not being able to install it
RKTools (inc the config file edit) will not detect the device even though it is seen in Windows.

I'll give this until 8pm and then it is going in the bin.
