Good day, guys. This is my first thread here, and it's safe to say that I'm a total noob when it comes to Nexus devices. This is my second Nexus device, and it's kinda heartbreaking that I accidentally bricked it on the second day of usage. What happened was that I flashed XenonHD ROM on it (did the usual wipes before doing so). It booted successfully, but after that whole finishing start-up screen before going to lockscreen, it reboots and repeats the process. So I attempted to go back to recovery via bootloader (CWM v18.104.22.168) to restore my back-up, but then it just got stuck at the recovery screen without any menus or options for about 2 minutes and then rebooted itself and went back to the same screen (cwm without any menus or options). And now, it's stuck there (the whole process which I now call recovery loop) whenever I power on my device and the only way to shut it off is by pressing and holding the volume up button. PS, I cannot access the bootloader after this happened. Whenever I try to, it just goes to what (from what I've read over and over from a lot of different forums and guides) people call APX mode. But they say that the only way to access that mode is if I press power-volume up simultaneously.
So my question is, is my nexus hard bricked (or any kind of bricked), or do I just need to have the physical button module replaced? If it is bricked, is there anyway I can fix this myself? Is there a process that I need to follow to undo this? I have searched far and wide, but it seems that the only way to unbrick this is if I can access the bootloader and go to fastboot mode, which I cannot at the moment.
Please, someone help me.
