So I am searching for a nightly or an official Cyanogenmod rom for my HTC Desire 620g dual-slim phone for about 5 months now, and I haven't found anything yet. I found a bunch of links which didn't lead me to a correct installation and it's not because I am following the steps incorrectly. I am 100% sure that whichever link's steps I followed were done just fine. I have installed custom roms in a lot of phones like Xperia M, Galaxy S4, Sony Ericsson Walkman, Sony Xperia Mini, and a lot more. However for the phone I have now, I just can't find ANY version of a cyanogenmod rom that works. Anything I do seems like it bricks my phone, so I have to recover it back to it's stock rom. I would really appreciate any kind of help. Also if someone knows how to and what to do to install a version of cm , please give me detailed steps, like how to unlock my bootloader on this phone, how to install the recovery mode either it will be a clockworkmod or any other, and finally how to install cmm. I am asking for so many details because this is the first time I am trying to flash a custom rom to a HTC phone. Thanks for any help that could be given.
