My laptop only has 1 user, it is administrator. Tried to switch users anyway but still only 1 choice.
I was reading lgm-dp also does a factory reset? The page I get up wants like 12 paths. Any suggestions on possibly going that route?
what does iparm 6 and 8 refer to in the programming, possible its radio/modem issue with the phone?
Dont remove the battery or you'll hard brick your phone

First, do you disabled the LG Modem driver? If yes, do you run KDZ as administrator (Right click on KDZ > Run as administrator). If it failed anyway, try everything, shake phone, reconnect phone but do NOT remove the battery!

Reviving a dead L9

Hello,
I've read numerous times about people being able to restore their dead bricked phones. No button combination will get my LG Optimus L9 P769 (T-mobile) to turn on. I think bricked it while trying to complete a carrier unlock. I understand that I can try to restore my phone through either fastboot or kdz. For fastboot, I was able to install the omap driver, but you know how I'm supposed to install a second driver? Well, I can't seem to do that. Maybe I'm doing something wrong? I would love an explanation of how to install the driver a second time. I know I'm doing something wrong, because when I use the fastboot script to flash the xloader and uboat, I just get "waiting for device." Also, if I want to flash a kdz, do I need fastboot drivers? I feel like my success depends on installing the fastboot drivers properly, but my computer and two others would not let me do that.
I'm really new to this stuff, so any help is appreciated! Also, please excuse me if I'm using the terminology incorrectly. Like I said, I'm new to all this.
Thank you in advance!
To install a kdz, you need to be in upgrade mode. Hold the volume up button then connect it to the computer.

Hello,
So I finally tried what you said, but it didn't work. Which program should I use to flash the kdz? Also, when I press up, should the phone have the battery inserted or not? When I tried the KDZ Updater, it said phone was not found.

Hello, I can't get into fastboot. It may be that the phone battery does not have a charge and so the fastboot script does not recognize it when I insert it into the phone after 4 seconds. Could that be a possibility? Because I tried everything, tried many different timings many times, to no avail!

I was just in the same boat as you and pretty much gave up hope but finally got fastboot working and flashed ics x and u and bam it worked like a charm on offline flash method. You just have to pit usb cable in phone w/o battery in and go to device manager. When you see it popup under other devices right click and press install driver. Make sure you have electronic signatures disabled or it will give a error and not install. This is what prevented me from getting it to work the first 100 times! Now run CMD. TYPE CD C:/FASTBOOT < OR C:/ W/E FOLDER NAME IT IS. THEN RUN START.BAT. < OR W/E THE .BAT FILE INSIDE YOUR FILE IS NAMED. Now press enter. It should prompt to plug in phone. I put my battery in as soon as plugged in and it worked. Now Choose option 5. Let it do its thing. Now go reinstall driver as done before to be safe. Then remove your battery. Hold volume + button and plug usb in. S/W upgrade mode should come up. Slide your battery in and proceed to the offline flash method to flash you kdz file. Should be alive again! Mine was tricky going into sw upgrade mode. Sometimes it came right up then sometimes it took 4 or 5 tries so dont give up! Goodluck and you can do it! I almost gave up I felt so hopeless about getting it to work then it finally worked like a charm!

I have a question, can a computer detect the phone with the battery in it? Like the omap4430 usb device? Because for me, the computer detects it whether the battery is in or not... both ways.

Yes it will detect it. However you need to install the omap in two different locations for it to work.

The problem is, I can't install the driver in the second location because it doesn't come up in device manager.. I was thinking maybe there's a problem with the battery, like it doesn't have a charge or something. Because when I run fastboot it doesn't detect the battery no matter what timing I used. I tried everything. If I use the old fastboot script and I get to "fastboot? y or N" and I enter y, it keeps asking the same question.

Yes, i've read that post (I think I've read everything on xda related to fastboot!) I don't get an inverted fastboot on the phone's screen. My phone doesn't turn on at all.. Like I said, I'm still struggling to get into fastboot.
Could be a problem with the battery? I'm going to get an external battery charger and try charging the battery.

Adb and lg g5, bootloader unlocking

Hey guys I'm trying to unlock my bootloader but adb is having none of it! When I type in adb devices it says list of devices but theres nothing there. And I can't boot into bootloader using adb. This is really starting to grate on my nerves as nothing is working. Am I just doing it wrong? I don't know. Should I have plugged my phone into the laptop before installing minimal adb and fast boot? Should I be switching to file transfer mode and/or photo transfer to install them drivers first? I've tried my previous questions and photo transfer is the only thing that comes up with adb interface in device manager BUT it will not install the driver it just keeps saying searching for drivers. any and all help will be greatly appreciated.
