I got my G2 D802 (International model) about 4 weeks ago, and rooted it almost immediately. It has been working great so far, but today I decided to try the latest CM nightly - and that's where I have hit a stumbling block.
I tried first by installing ROM Manager (5.5.3.0, latest version at the time I am writing). Under Recovery Setup, I found that I supposedly had already installed both ClockwordMod Recovery and TWRP. I honestly don't recall installing either one, but the options were available. I tried to "Reboot into Recovery" first with CWM, then with TWRP - both times, after the initial LG logo, I was greeted by the broken android with the red triangle. I also tried to reinstall CWM by choosing the corresponding option "Install or Update Recovery"), but the result was always the same. Each time, I was able to restart the phone, which is still working fine.
I then decided to flash a new CWM. I downloaded CWM Touch, then used Flashify to flash the new image and reboot the phone. This time, the boot process stopped after the LG logo appeared, but an error appeared right above it. I repeated the process two more times (once with CWM Touch and once with the default CWM), and the message that I read was something like:
At this point, I am wondering if the problem might be a locked bootloader, or if it might be something else altogether. Could someone please point me in the right direction? I am not exactly a noob, as I used to root and flash my Nexus devices in the past. After a couple of years using Asus Padfones, however, I am a little rusty.
