[Q] Upgrade program crashed, stuck in upgrade boot screen. Now what? SOLVED!

Like the title says:
I just tried to upgrade my Optimus 2X via PC software. The package downloaded fine but in the middle of the upgrade process the PC software crashed(!) and now I have a phone which is stuck in the upgrade boot screen saying:
"S/W Upgrade
Please wait while upgrading..."
So, what now? Any way to get this thing working again?

First, remove your battery and put it in your phone. Boot the phone up and see where it goes. If it goes into S/W mode again, that sucks. If it goes to the LG boot screen, put the battery out again and put it in. Press Power + Volume Down buttom to go into the CWM menu. From there you can restore your backup (if you made one) or mount the SD card and put the (rom).zip file in your SD card. Then just flash the zip from the CWM.

The update process by LG is pathetic. Many a times, I had the same problem as you. It would just get stuck. It is because of faulty drivers on their part, unable to maintain a connection with the phone.
You can try to NVflash clockwork mod recovery (CWM) and then recover your data.

i have the same problem.
i've tried everything without luck.
mine stopes att 4 procent and pc is trying to install some new device
lge mobile composite usb device.
there is no way to work around this issue.
i have tried absolutly everything.
wipe, clean, drivers this that. hard reset, variations in installing, i don't know what else i can do,
this is the message that cousing all of this.
this is located just in upgrade mode
the device is called
LGE mobile composite usb device
Universal Serial Bus controllers
LG Electronics Inc.

Thanks for the infos. I managed to install a stock rom and baseband with SmartFlash yesterday. Just a few minutes ago I used LG's update tool to update the phone to Gingerbread.
So, problem solved. If anyone has the same problem, follow these instructions to update the baseband:

problem in updating

hi
i was updating my phone with standard method with lg program.. (without downloading kdz file separately)
but an error occurred in 15% , " ..
"problem communication between cell and phone"
and my phone has locked in s/w upgrade mod and don't turn on.. even if i put the battery off and insert it again it turn on , in s/w upgrade mod...
please help..

If it's still at 15 % it shouldnt even have started flashing U are lucky so to say
Just pull out USB and battery, wait a few seconds and restart. Then try to install the latest drivers, maybe run it as admin or another PC if available.
If it's stuck in bootloop, try emergency recovery in B2C tool (LG update tool), or read in my noob how to, how to unbrick devices.
Also this thread needs to be in Q&A

I was using 64bit PC and had the same problem then I used another PC and the problem was gone

Had the same problem. Resolved using emergency recovery in LG tool, but using another pc.

Try to reboot bootloader in ADB before re-flash, maybe it helps...

Before flashing kdz try wiping data/factory reset and format system. After that turn off the device from recovery and flash kdz. Ofcourse dont forget to backup ur stuff.

Soft bricked VZW G2 and can't install drivers

I was trying to flash the lollipop kdz to my phone and was having problems with drivers but then one time it apparently was working but it still gave me an error popup so I unplugged it and now it always boots into firmware update mode :crying: Now I can't get the drivers to install. It shows 3 devices: Mtp device, LGE Android phone, and CDC Serial port (this is just from memory so the actual names might be slightly different). The MTP device always gives the error "Failed to start" and the other 2 say no driver found. I have tried different pcs and driver versions with the same results. I tried this but it says no drivers found. Does anyone know of a fix for this? Is there a way to manually specify the drivers to use or something?

I updated the drivers to the version from LG's website and now the drivers seem to be working except for the mtp one. Now when I try to flash it give the error "Connection to server failed, try again in a moment" and if I click retry it fails with the message "Upgrade stopped due to an error". Anyone have suggestions on how to fix?

Update: I tried the tot method as well and it fails with an error getting model name.

Make sure that you have the correct drivers installed. For Verizon they should be the LG_VZW_United_WHQL_v2.20.0 one. Use the lg flash tool 2014 http://forum.xda-developers.com/showthread.php?t=2797190 and a kdz file. I believe that you can update to lollipop directly with the lg flash tools. I could not install the lollipop kdz as I kept receiving the same issue "cannot connect to server" so I installed stock 4.4.2 that my device came with and updated to lollipop ota. If you install the the same stock software that your phone shipped with it will still say "cannot connect to server" but it will indeed update your software. I believe that the key is to making sure you install the same stock software your device shipped with for it to actually update to your phone in my experience.

I am using the drivers you mentioned. Do you know if the mtp driver failing is an issue? Also, I tried 3 different kdz versions with the same results.

Do you have a custom recovery like TWRP or CWM?

Alcatel Idol 4 6055K problem with firmware

Hello,
I have a somewhat aged Idol 4 lying here.
This no longer boots or it hangs in the boot loop.
So I tried to install an update via a stock rom from the network via the recovery menu and ADB sideload and always got the error status 7. (Alcatel_Idol_4_6055K_01001_01002_OTA)
Resetting the system didn't help here either.
Then I tried to install TWRP on the device.
But unfortunately both methods that I tried failed.
Once via Sahara & firehose-test and the second was Suger QCT via the download mode.
But both of them got the error message NPRG Error 5002.
I have installed suitable USB drivers.
So my question, does anyone have a tip for me on how I could get the device revived?
And Sorry for my bad english

Hello, I deleted my system from twr without realizing what I was doing, the result is that I stay on the Alcatel logo. My steps were, the installation of sugar, when it starts not to update the application. Choose the 6055 model, since the 6055P model that is mine does not appear in the drop-down. Before starting sugar, turn off the mobile completely and connect it off to the usb of the pc, check if when connecting it the pc does not detect it, use another cable (there are many cables that only serve to charge and not to read on the pc) Now start sugar, choose the model and click on the Udgrade tab. You will surely get several messages saying that the mobile has been modified and that you lose the guarantee, go ahead accepting the message, in a few minutes you will have it ready. Greetings.

Hello, thanks for the answer and the download.
I've tried the same way. I still downloaded your file and tried as you described.
Unfortunately I got the same error NPRG Error 5002 again.
Unfortunately I have no idea where the problem could be.

I found out that it could be a memory error.
As if a flash process had failed and there is no longer a correct series of partitions.
So I would need a complete original rom and would have to flash it via fastboot.
I could also try it via twrp, but I don't get this flashed.
And I don't have a complete original rom either.

Hello,
So I have now been able to flash the phone with another PC with Sugar QCT after it suddenly started up after the battery was completely empty and I charged it again.
But unfortunately the boot problem persists after turning off the phone again.
Even after replacing the battery with a new one.
Then I tried to flash TWRP via the Alcatel Flasher.
The flash process was successful but there was no TWRP on it after the reboot.
So the problem could still be somewhere else than just the firmware.

Hello, it may be that you are making the same mistake that I made when installing recoveri. When selecting the recovery, note that the twr is the one that weighs about 14 mb and the original one about 24 mb. I think that when you make a copy with the recovery program and then install the twr you select it wrong. In the program, do not make the copy of the recovery, skip that step and go directly to install and select the 14 mb file. You will see that this is the problem. Cheers
