First of all, yes I have gone through droves of posts on XDA and frankly it’s a mess, but I can tell you that after following a few threads that just refer to themselves in loops, there’s no actual solution.

I have an LG US730 which was rooted and everything was great. I must have toggled something in SuperSU - I think maybe the option to be rooted during boot.

Anyway, now all I get is Security Error and it shuts off. None of the recovery power on switches will work. The only thing I could do is VOL+&- power while the usb is plugged in and it goes to a download in progress screen. Of course nothings happening and I need to remove battery in order to get this powered off at this point.

Anyway, I’d love if anyone has a tool to repair this. LG’s utilities all do nothing at all I think they’ve purged the back-end of older stuff so the programs that should download something and proceed simply wait forever.

    When “download is in progress” appears, do you get anything out of fastboot devices? If not, the phone is probably bricked. If so, you should be able to reflash the OS with fastboot commands that should be in the various threads on XDA.

      Figured out what you meant. No, fastboot devices does nothing. And I did search xda I can’t find anything that makes sense.

        Just to confirm, when your phone is connected to your computer with a USB cable and in the download in progress screen, running fastboot devices on the computer shows a message to the tune of no device connected?

        If that’s the case and the other startup combo actions do nothing, the phone is dead.

          Yeah neither adb nor fastboot see it.

          This really sucks. It would seem it’s bricked, but then I have read lots of articles that swear that it is not hopeless.

          The problem is LG has purged all files related to this device. Any download links or menus etc. you can find lead to dead links. I spent many hours and checked easily like 20 websites. There’s absolutely nowhere to be found an original rom image. Nada, nischt, zilch, bupkis, squat. Even the few XDA mentions are dead links :-(

          I’d love to get it running again, but for now at least, I have stuff to do so this goes on the back burner. I have it in my box should I ever want to take another crack at it.

          Say… you feel up to a minor challenge? I have like a dozen devices and I wish to document what are the possibilities for each of them, vis-à-vis alternate rom such as havoc, resurrection remix, etc., or aosp / gsi, or just rooting if that’s all that can be done. This way I can know what to prioritize trying.

          I gotta tell you I find the XDA forums to be absolute chaos and incoherent. I’ve tried very sincerely to make sense of it, but sometimes I go to the forum for a device and it’s post after post with titles that don’t even contain a single actual word, it’s just acronyms and version numbers. And I’m sure that makes sense to the pros, but I can’t even figure out where to look for a starting point. So that’s why I’d like at least to catalog my options and then I can proceed knowing I’ve got starting points to look for.

          If you’re up to it let me know I’ll post a pic of all the devices labeled. No worries if you’re not interested, I know it’s a pain in the ass what I’m looking for. Anyway thanks for trying to help with the LG. I’m not giving up hope yet, I love that little phone it’s sweet.
