Bricked Nook. Will Pay GBP10 if someone can help me fix it

Hi,

I have broken my sons Nook by trying to install CM11 on so he could install and play newer games.

The error message I am getting is Error 7 everytime I try and upload the ROM. I have googled and googled and cant find an answer as it seems to be the newest one. 6.0.4.6 status 7

I have tried a restore, from the 2 x back ups I did however some file is corrupt and it gets stuck on boot.

Its a bit of a mess, so would pay £10 by Paypal for someones time to help me resolve it and get CM running

I am not sure what to do now

Thanks

Barry
