If it does get past that stage (not all the time) it will display the following

ERROR: can't get kernel image!Reading on here it seems to be a known issue with a firmware upgrade, I have attempted to re-flash the firmware however this never resolves the error. Is this router bricked now or is it possible it can be recovered?
On a side note, when its powered on the power light stays solid green (never changes, even when doing the 30-30-30) and the ring lights sometimes flash white.
, I did buy it as parts only, hoping it could be fixed, but wasn't the most expensive so at least I have learnt a bit along the way.
