I'm trying to fix my boss's phone.
Phone won't get past LG logo. Tried connecting with adb and device is not being recognized, although when I reboot into "emergency mode" and connect via usb, I get a prompt on my Mac asking if I'd like to use the phone as a modem.
The phone is not rooted and used normally. It just happened out of the blue one day. No exposure to moisture or drops.
Is it possible to flash the stock rom/factory restore without root access?
Any help would be greatly appreciated.
Try to do a wipe
Press Home+Vol_down+Power in this order when you start the phone, and hold them during the LG logo
Wipe won't work, as the phone is on stock ROM (no custom recovery menu). But there is a way - read this. It's a lot to read and a few more links to follow, but it will pay off, because it works.
yep. it works 100%. I bricked my o1 3 times already and it worked for me every time.
You may be able to restore your phone to factory settings by pressing and holding the Home button and Vol down while pressing the power button. It will enter in recovery mode (stock roms have a sort of recovery where it restores you phone to factory state). It will reinstall your os and native apps, but you will no longer have your contacts, sms, pictures etc...
If not, just go with what masteryx told you.

Hi there,
Some weeks ago, after many months of low space problems, I did a factory reset instead of deleting app by app.
But after that, I started having some problems:
Home button doesn't returns to Home, but it still works for mousing off the screen when it's off
Recory is missing
I give apps root, but they don't turn root.
The home button ... well, I can survive without. The Recovery... I haven't used it since I installed it. But the root is very important, as I want to use many apps but I need root to use them.
So well, let's try another factory reset. But nothing changes. So... let's change the ROM. But hey! I need recovery for that...
I haved tried many times to root or unroot the mobile, but it doesn't works. I have done it using many ways in Windows and Ubuntu, but nothing works.
Do you have any ideas about how can I fix this problems?

Instead of tweaking your device by rooting it or unlocking it.. I suggest you to repair the phone's software by PCC or SEUS!

To install recovery use xparts from playstore!
Or if your bl is unlocked then flash any kernel using fastboot! Every kernel with itself has an inbuilt recovery!

I managed to access recovery. And I installed a ROM, hoping that it could repair easily all my problems, plus upgrading my phone at the same time. I installed this one http://forum.xda-developers.com/showthread.php?t=1880321
I downloaded all the .zips I saw, and thinking that I could merge all them into a single one, I did. I though that this was the way to do it.
I did a backup of the phone, and erased cache, dalvik and did a factory reset. I installed the merged .zip, and after reboot:
The phone boots, the "Sony Ericsson" screen lasts for a few seconds, then I get a black screen for a few seconds, and the "Sony Ericsson" screen appears again, to dissapear, and keeps looping indefinitely.
I have been trying for a while, but I'm unable to boot the Recovery or even the Download mode. Maybe I don't know how? What I do:
Press power until it boots, wait until Sony Ericsson logo appears, start pressing Vol Down again and again <-- This worked for me earlier for accessing recovery before installing the zip
Hold power, home, and Vol Down (When doing this, after each 10 seconds (after the Sony Ericsson logo fades away, the mobile vibrates shortly, like when powering it off)
Hold power, home, and Back
Hold power and back
Hold and Vol up
Have I bricked it? How could I repair this for installed each zip one by one?
Guess that by now, I'll have to search my wristwatch.
To Enter Recovery:
You have to press back key again and again while booting(on Sony logo appears).
To Download mode:
Power off the phone.
Then plug the usb while pressing back key.
To Fastboot mode:
Power off the phone.
Then plug the usb while pressing menu key.
To Install a stock rom:
Download a Stock rom.
Then flash it via Flashtool.
or
Use PC Companion to repair.

This was the solution. I though that it was some ****ty software that wouldn't work properly, but I have to say that it's intuitive, and have repaired my phone without problems.
Thanks a lot. This have returned my phone to the state of after-buy, which is why I did the factory reset that made so much problems. Thanks!
Yesterday I rooted my LG Optimus L9 using LGpwn tool, after that it worked just fine.
This morning I tried to install ClockworkMod Recovery. Using this post. It explains how to download and install CWM Recovery from app that you downloaded in form of APK.
This method did not work 100%, but I was able to reboot normally, so in post it said that sometimes it does not work and you need to download and use Busybox installer Link to busyboxx.
After this I managed to boot in too CWM using app from mentioned thread.
Then problem occurred. After I saw CWM was working I selected reboot device option.
Except now when it started to boot it stops right after Second LG logo (First is static one second one is animated).
I get white screen with "Encrypting" on top and gray line. And one Reset Phone button. IMG they are Dropbox links.
This is followed with Error : Unfortunately, the process com.android.phone has stopped. IMG
I am able to boot in too CWM and I have tried flashing something like Cyanogenmod but I get error Status 7. Tried removing line that checks model, no use.
Tried clearing every cache and fixing permissions, nothing. Formatted everything still no use.
Dear XDA community That you in advance.
I fixed my phone by going into SW upgrade mode, and using the Upgrade Recovery function of the LG Software Update tool or whatever. Be sure you don't have any http servers open

I got the same problem, but when I try to access to SW mode and connect to LG Software Update tool to restore my phone, the phone keep disconnect and the phone screen will turn off, so I fail to restore my phone, I have already re-install the USB driver and changed a several USB cable but the problem still, but I tried to restore my phone with SW upgrade method since last night and is was OK, can anyone help me?
---------------------------------------------------------------------------
The Problem Solve Finally, the solution is I plug the battery back to the phone after access to LGMobile Support Tool, and after finish the restore process, the phone will restart but keep boot loop, then I perform the hard reset (Remove the Battery and insert it after few seconds. And now do the 3 button HARD RESET. First press VOLUMEDOWN and HOMEbutton. Then Press Power button only for 3 seconds and release power button but dont release VolDown and Home button and KEEP BOTH PRESSING until you see a Bigger Green Standing Android and circulating Molecular structure above it. DONE! ), then the phone begin work~~~

Hello, today I wanted to restore my previous CWM backup. So i started with cleaning partitions before restoring. I've begun with system and my phone hang. I waited about 30 minutes, then pulled out battery with hope I'll try again via CWM. The thing is - I can't boot it into recovery: Volume Up/Volume Down+Power leads to normal start up (LG screen and nothing further). So i connected it to PC and wanted to make it right via ADB. Unfortunely it seems I had USB Debugging turned off, and ADB isn't recognizing my phone now... What should I do now?
I have rooted D620r with unlocked bootloader.

You must never delete partitions before restoring a backup especially system!!
CWM will do that for you...
Boot your device in factory reset mode (which simply boots CWM) by doing the following key combination: (while your device is off - pull and plug the battery to be sure) press and hold Vol - and power, when you see the LG logo, release the power button and press it again. Hold them until you see the facory reset mode, then simply enter YES. It will reboot to CWM.

Weird, I was always doing this when I had HTC Desire S
Used this countless times and always worked!
Ok, i've done as You said, something like CWM loading screen appeared, and then went back to LG Screen. LG Screen standing still and nothing happens
The only good thing is that I can access ADB for 20 seconds when CWM is "loading", but no action can be executed - every command ends up with "waiting for device".
Thanks for Your reply, though! :highfive:
EDIT:
I solved my problem by using "Emergency software restore" mode featured in "LG User Support Tool". I got clean, unrooted system now and I need to modify it again but...

Lock bootloader
Hello everyone.
I was just going to try out CM11, but got one question. Is it possible to lock the bootloader and revert everything to stock? There were some talks about new stock ROMs coming out and they might not work after a custom ROM.
Hello all, thanks for helping me out.
I did a very foolish thing. I rooted my phone and deleted a few bloatware apps that were apparently very important to the phone's functionality. I did not install any recovery software like CWM, fastboot, or anything. It was a stock phone that I simply rooted to remove a few apps. When I went to restart my phone, I found out that I bricked it. Now my phone will only enter Download Mode if I hold the up+down volume buttons and plug it in, or it will get stuck on the LG logo screen and a Security Error screen. A factory reset with the volume down + power will work, but does nothing to fix it.
My immediate issue is that when I plug my phone into the computer, the phone will recognize it has been plugged into a power source (it will either go into Download Mode if I was hitting the volume up+volume down buttons, or start trying to boot up but cycle through the LG logo screen and Security Error screen) but the computer will not acknowledge that anything has been plugged in. There is nothing new listed in the Device Manager. I have read other threads and searched around on the internet. The usual solutions are not working for me:
I have tried several other cables and computers to no avail. I have also tested my current computer/cable, and it worked for data transfer with another phone (Nexus 4)
I have tried cleaning out the contacts on the phone. They were not significantly dirty.
I have tried installing the drivers from LG and even the UniversalNakedDriver
I believe that if I could get my computer to see my phone, I could flash the stock rom back and restore it to working order via LGNPST. I know it is simply a software issue, because prior to my rooting the phone it was recognized by the computer.
Does anyone have any other solutions I haven't tried? Or is this something I need to go JTAG on?
Hi everyone, I followed this guide here https://forum.xda-developers.com/t/v60-bootloader-unlock-and-magisk-root.4358785/ to root the phone with magisk. Everything went great up to the last point. I rebooted my device and I am currently stuck at fastboot mode as my device can't normally boot into stock rom I had before I tried to root it. Should I just flash stock rom on the device? How should I do that? I am still an amateur and can't figure it out by myself. My bootloader is unlocked. Any help would be much appreciated. Flashing backup boot images doesn't help.
Just put your device in the download mode. Here are the steps for you:
1. When you are in the fastboot mode, choose to turn off the device by scrolling though the options (via volume up/down key and then pressing the power button to select).
2. After the phone is off, keep the volume up key pressed and insert the USB cable into the device. Make sure the USB cable is attached to a computer before plugging it into the phone. This will put you in the download mode.
3. From there you flash the relevant firmware using LGUP.
The case is outdated, I managed to upload the firmware via LGUP
Hi everyone.
I have a similar problem. I wanted crossflash to EU.
When I was ripping and deleting the contents of the partition, the phone lost the usb connection and after reboot it fell into a loop. It does not report for usb and I can not turn it off. Is there anything else that can be done to save him? I erased the partitions FTM, Modem_A, Modem_B, SID_A, SID_B, OP_A - not OP_B.
I have a backup of them
I'm sorry, my english is bad.
You have two options depending on which one is available to you:
1. If you get into the QFIL then try to restore the deleted partitions. It is quite possible that other partitions have also got affected due to abrupt disconnection resulting from power failure.
2. Maybe you can get into the download mode. It will be tricky. Press and hold the volume down key and the power button till the phone restarts. Once it starts, press the volume up key and insert USB cable (that is already connected to a computer). Once there, re-flash the firmware.
Thank you for your help. I was able to start the phone in download mode and upload the firmware via LGUP.
Hello! I didn’t root anything, everything is stock. at some point phone just crashed and now it is stuck in boot loop. i was able to factory reset it, but nothing changed, it keeps rebooting. LV600AM
The problem, in your case, becomes complex because AT&T does not release firmware publicly (that you could just re-flash the phone with). How were you able to factory reset the V60 phone? Did you get into the settings menu and reset it from there?

i was able to use power/volume down feature to get into factory reset menu, wipee everything, but nothing changed. it just keeps rebooting till battery runs out
I hope someone here could share with you a full AT&T V60 partition dump. Failing which your only option is to have AT&T restore it for you.
