[General Topics] bitwhale:
Hello, thank you for this thread, I appreciate it, it's literally the only one of it's type that I can find and I'm pleasantly surprised that its not all that old. I am having some issues, first let me explain what happened:

I have 2 lg optimus zone 3 verizon that I have rooted. I used kingroot & bought supersume pro to switch over to supersu, I downloaded kingroot 4.8.1 as instructed in the directions, rebooted after rooting, downloaded supersu & supersume, rebooted again, ran supersume & all went well. It opened supersu after wards and said something about needing to update my SU Binaries before continuing and gave me two options, normal, or TMCP (i believe). I did a little research and it seemed to be general consensus that TMCP was the better option, so i clicked it. It said "Ok we will try to update" and then about 30 seconds later my phone auto-rebooted & wouldn't boot past the logo screen (what I believe is referred to as a "boot loop" even though nothing seems to be looping, just frozen in place).

I've read a bit, it seems like it's definitely the SU Binaries, I wish I knew how to fix this. I have tried all of the normal, hard reset by volume+ & power, didn't work, and then I found this thread.

For the first option: I downloaded the software repair assistant as well as the lg united drivers provided, I opened the repair assistant and plugged in the phone while holding volume+ so it goes into download mode. The assistant recognizes the phone, checks device data, tries to backup but fails, says it will need to wipe everything, i click ok, it downloads for about 35 minutes, all is good, then we get to the stage "repair" and it gets stuck at 20%. It hasn't moved since for over 1 hour. Not sure what to do, I'm quite afraid to unplug the device at this point though I'm pretty sure nothings changed as it seems like its stuck at the same point as when I try to boot up.

I am going to leave it overnight, but what should I do when I wake up in the AM? If I unplug it during the "repairing" phase, is it going to make the situation worse? What should I do?

Ok, for the second option (i tried it earlier before i got the first version to work): I download all of the files in the link provided and installed them. I open LGUP and put my phone into DL mode. It recogizes my phone, I select it and click ok and then I get the error: "LGUP can't load the model[C:\Program Files\LG Electronics\LGUP\model\com". I went into device manager and checked for my drivers, it does show I have issues. My LGE Android MTP Device says "This device can not start (code 10)" {operation failed} the requested operation was unsuccessful. I went ahead and clicked into it and clicked 'Update driver" but it says I already have the driver which is most up to date.

I have got into the file explorer to the LG\model folder and there is a VS425 driver there, with the dll inside. I notice tht there is no "com" folder. I've tried pasting it directly to the model folder, leaving it in the vs425 folder & creating a com folder and pasting it there, none of which seems to work, i always get the same error. How do I fix it?

Thank you, hope you are well, happy new years.

PS: If you can get my phones back up and working, I will tip you $10 in bitcoin, lol :) I want them working that badly... I've been battling this for days now.
