Did you choose the Wipe Cache Option from the menu?

I have tried all of the factory reset options ;- nothing changes.
I tried all options; all I could find on the internet
ok, if you also wiped the cache and still it will not boot then it confirms
it is the internal memory that has faulted.
A corrupted firmware can cause this. But this has been ruled out by the reinstall. Corrupted cache is also not the issue if you have wiped this.
This confirms its the memory that's at fault, which is part of the logic board, its this that needs replacement.
I am really sorry about this and you are going to have to return the phone to have it replaced. It will be covered by the warranty if this has not expired, and the replacement will be done at no cost to you.
I am really sorry about this, and if you have problems, or would like any additional information or assistance, please do not hesitate to let me know.
And if you can take a second to rate my service, that would be greatly appreciated.
Thank you

Hi: thanks for your attention to my problem.Before going further I decided to refresh my knowledge of smart phones and conduct another investigation. THis investigation eventually took me to an app which was corrupting the cache as soon as it became active. Removing the app solved the problem; pity as it was a useful app and it works OK on my tablet and other phone. This info. may be of use.
