I kept playing with it an finally chose the 'power off' choice.

Its turned off and on and it entered the UT set up.

So it is possible to install without selecting developer mode.

Thanks again for the input

Appreciated

Its from UT.

Then blank.

Thanks but I checked the docs and could not find the answer.

Ive tried about 20x to install it. I'm sure there is a way to do it.

No it shows the installing updates screen then goes blank. I havent been asked for a password or code

Ive been using Ubuntu for since 2006 and started on Red Hat before that. I really appreciate the great software.

Anyway, Ive bought a Nexus 5 on ebay.

Thought I followed the install instructions but I've missed the 'Enable developer mode' step, and flashed Touch onto the phone.

How do I get around this?

(I'm not concerned about losing data)

Thanks
