htc one mini 2 in boot loop

[JeffArnold76]

hi happy new year blah blah

well as the title says my phone is in a boot loop the furthest it will go is the white htc screen i didn't try messing around with new android platforms or try changing the os one moment it was fine the next it was stuck in bootloader

I have tried factory reset reboot recovery, recovery shows a phone with a red triangle
i even tried downloading an ruu and flashing with command prompt but that gave a response of remote signature verify failed (i don't really know what i'm doing just reading forums)
hboot shows op8bdiag.zip no image op8bdiag.nbh no image or wrong image

i'm in the uk and my phone is locked to o2 OS is 2.19.206.4

i don't mind installing stock os or maybe something else seeing as my warranty is useless lol
an o2 "guru" reckons 9 out of 10 times it's a blown chip and you cant do anything. . . . . . .

found correct rom still struggling to get it to work, phone offered to update to rom itself but didn't seem to do anything

i thought update utility might work but it said my phone was under 30% battery even though it's not
