thanks very much Caspan, for taking your time to write so much !!
I tried this and feel that I got the timing with the battery correct because all the installation steps seem to happen finishing with a positive screen saying all done Forgot the exact words
But I still get the same endless boot loop.
The Bold is updating once more now but I am not holding any hopes !
Been at this all day! I will try again this evening !
edit - still no success,,, I read that a reboot might take as long as 15 minutes... so waiting a little longer
Any further advice is much appreciated.
