(I originally posted this in xda-developers forums, I just want to gather as much help as I can) So I was about to install CM10 in my One V. I'll try to describe exactly everything I did. It's my first time flashing a ROM, so I was following these instructions http://forum.xda-developers.com/showthread.php?t=1918100 since they're the only detailed instructions I could find. I was using the latest CM10 from maxween http://forum.xda-developers.com/showthread.php?t=1996761 (CM10 2012-12-08). Since Maxween states that the boot.img is in the ZIP, I went on to extract the boot.img from the CM10-20121208.zip. I booted into HBOOT, plugged my phone and went into FASTBOOT USB. I went on to flash the boot.img Following mattxhtc's instructions, I tried to booting up the phone to check the kernel version (note that I didn't unplug the phone from the computer), and now the phone won't boot up. It goes up to the HTC ONE animation, the jingle suddenly cuts off and the screen stays stuck there. I can still restart the phone and go into HBOOT. I tried restoring using a Nandroid backup but the problem is still present. I'm currently trying to restore it once again. Any help? Where did I mess up? EDIT: The restore just finished and the problem is still present! EDIT2: I tried following mattxhtc's instructions again and flashed boot-TK-USB-CM10-201209091500.img from his guide, and the problem is still present... Help please, I'm freaking out!
