I installed the official ROM by SP Flash Tool (Download option).
Everything worked, but after a month the programs themselves started to close.
After several months, when I installed ROM again, the program did not want to install the system - chksum error (which was not previously). The phone became soft-brick - only the phone's landing screen switched on.
I tried to continue to install the system with this program. After that the phone stopped turning on at all.
I installed the SP Flash Tool again on my PC.
This time, SP Flash Tool installed Android on the phone without any error.
The phone can not be started at all.
Question:
How to find out what went wrong? Apparently there are some checkpoints on the phone's motherboard?
Or maybe you can run it somehow?
What to check?
I heard about the method of applying voltage to the motherboard (?).
Particularly interesting is that the system is installed automatically.

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

Windows cannot verify the digital signature for the drivers required for this device. A recent hardware or software change might have installed a file that is signed incorrectly or damaged, or that might be malicious software from an unknown source. (Code 52)
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:

Rooted LG D405n, nothing done to the software beyond that (unless you count having zooper/nova launcher configured on it). Gave the phone to a friend for a short while and she decided to update the software using the LG software update on the phone. After she selected install on the latest update which came out not long ago and was supposedly going to update the apps, it restarted and got stuck on boot screen with Boot Ceritification Error [560].
I've tried this guide http://forum.xda-developers.com/lg-l90/general/guide-flash-stock-kdz-offline-lg-l90-t2803479 but I got stuck on step 4. because I cannot make the PC recognize the device (it does not show up at all), so the LG tool can't install USB drivers. If i try to do it manually (it gives me an option to select a device from a list) it doesn't seem to do anything, just gets stuck on the Downloading USB driver window.
I can put the phone in Firmware Upgrade Mode just fine, but it doesn't seem to do anything useful. The PC still won't recognize the device, however I can hear the 'usb pluged in' sound (I'm on Win7).
Did a factory reset, didn't help.

You could try the LG Support Tool. Not sure it will work but it's worth a shot. The problem with the phone not getting detected by the PC is the fact that 1) The OS was upgraded by your friend and 2) The factory reset you performed . Both of those acts would have disabled USB debugging hence no device detected.
I unfortunately have no encouraging information to give you.

It appears that I have fixed it.
Since The tool would not download the USB drivers by itself I went to the LG website and got them manually, installed them and restarted the PC.
After that I launched the LG Mobile Support Tool, but it still didn't see the device.
However, I clicked Options and Upgrade Recovery. It asked me for my IMEI. I put the phone into Firmware Upgrade mode and the program started upgrading the phone.
After it was all done, the phone restarted, and the software update simply said that instalation failed, I have lost root but everything else seems fine. Rooted again with towelroot and I'm back in game.

Well I'm glad you managed to fix it.
Since this issue appears to be solved, please insert '[SOLVED]', without the quotes, at the beginning of your thread title.
I have half-bricked P880. Bought just a week ago.
My ROM is stock V10C. I’m trying to get rid of that crap ROM, but so far without success.
I have rooted the phone but flashify is the only app saing that the phone is not rooted. Every other app which requires root is normally working. I can’t unlock the bootloader because phone can’t be recognized by any computer, using different Windows, USB cables etc. It just shows charging but PC doesn’t see any connected device. Nor the phone shows any connection option when I connect it to PC by USB.
I’ve tried to install TWRP (without success) and CWM (successfully) but the phone can’t be load into bootloader. Just an LG logo will appear and this error message:
[LGE_SECURITY ERROR] boot image signature
Critical failure: Unable to start kernel
Unrecoverable bootloader error (0x00000002)
I think it’s still locked.
This method hasn’t help either…
http://forum.xda-developers.com/showthread.php?t=2251407
What’s more, the error message appears almost every time I try to turn on the phone. Sometimes it takes 10 attempts until the phone will finally boot into Android.
Yes I’ve tried basic things like playing with USB debug mode, LG PC suite option/USB tethering… please don’t respond to my question by that kind of suggestions, I’m no rookie in flashing roms and Android problems.
Only hope for me is to flash kdz file via PC (when the phone is off and battery out). BUT I’m unable to do that, due to problem that the phone is again NOT RECOGNIZED by PC. Of course I've tried every kind of LG driver but the problem is in the phone, because the PC won’t even notify by sound that a phone has been connected to it. So I need to change the corrupted bootloader… somehow.
I’ve already searched everything to this issue on XDA and elsewhere - without any solution. So I’m 95% the phone is half-bricked without any chance to flash new ROM.
If none of those things that you said doesnt work, as last resort you should try this

Thank you for a quick reply! However the autor of the method says:
i mean when you get stucked with S/W screen, and you can't flash the device in any way
Click to expand...
Click to collapse
In my case I can't say that I'm stuck with S/W screen. Because I don't even get in there. Any PC in my home (XP/Windows 7) don't even recognize that a mobile has been connected to it. So there is no S/W screen. The only way I can get in S/W screen is to keep the battery in, but it doesn't solve anything. Because the phone remains unrecognized to PC. Therefore I'm unable to flash anything. A simple explanation in here arose: the USB port in my phone is faulty. BUT, how that can be, when the USB charging works fine and even S/W screen appears while the battery is in?
Either way I'll keep your suggestion as the final solution(since I'm very skeptical of it and also dont have screwdriver small enought to take out those tine srews) if there will be no other responce to my problem.
I'm not very experienced in things like this, but when I was flashing kdz to my phone, my computer wasn't able to recognize the phone with battery out, so I did whole process with battery in (and it worked)
anyway if you want to unlock the bootloader you have to update to official JB (just flash JB kdz and then wipe data in LG recovery to prevent bootloop)
so first you have to connect somehow your phone in sw mode to computer
then flash JB kdz and wipe data in LG recovery (it should be back even if you've flashed twrp)
and finally root JB and unlock bootloader (for example this way I found by two clicks here at xda, just browse Optimus 4x general category: http://forum.xda-developers.com/showthread.php?t=2251407 )
I hope I helped you a bit
I agree with you SuperLamic. Especially with this:
so first you have to connect somehow your phone in sw mode to computer

My only hope is to flash kdz file using fastboot mode. However after days of searching on XDA, installing all kinds of drivers, trying different methods etc., I'm still unable to connect my phone to PC.
Any PC I tryied so far haven't even made a sound while pluging my LG to it. Nor it's vissible in the list of connected USB devices.
So now I'm sure that a USB port on my phone is faulty There is no other possible explanation. But thank you all for your suggestions anyway.
P.S.
There is maybe a tiny chance for workaround by unlocking the bootloader without PC. But this method doesn't work. http://forum.xda-developers.com/showthread.php?t=2251407 With unlocked bootloader I woud be able to solve the problem without PC. Right now I can't install TWRP nor CWM because they require bootloader to be unlocked. CWM in ROM Manager always says that installation was successful but actualy, it wasn't. Since there is always this error when I try to load recowery mod...
[LGE_SECURITY ERROR] boot image signature
Critical failure: Unable to start kernel
Unrecoverable bootloader error (0x00000002)
EDIT:
So I find out that only JB ROMs can be unlocked. It's not possible with my stock ICS. So there is really only one solution: repair my USB port on LG to flash kdz. But I'm afraid that these days a repair will cost more than the phone itself :[
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
I have a OnePlus 8 Pro running Oxygen OS 11.0.4.4.IN11AA. Upon installing Magisk, I can no longer turn Wifi on. I have tried restarting, clearing the cache from recovery, resetting network settings, basically all the things the "wifi wont turn on help pls" guides say to do. Mobile data and bluetooth work absolutely fine, so what's going on?
Sound is also non-functional. Even after plugging in earphones (which worked with this phone previously) nothing comes out, and the phone doesn't even seem to recognize them. I also noticed that after a reboot the volume controls are set back to the defaults.
Additionally, the system is very slow to start up and the screen stays black until after the unlock prompt (which displays over the black screen) and then the wallpaper and everything else loads. (after which the device is responsive as normal)
These problems occurred even without installing any modules or otherwise modifying the device. I'm using the latest version of Magisk, 22.0 (22000).
I originally tried to make a GitHub issue, but it was closed by the bot since I didn't follow the template GitHub never showed me. Also, us non-canary users experience issues too. [mini-rant over]
Sorry if this is a duplicate, the search system appears to be malfunctioning since the updates.
The Fix!
Looks like I'm solving all my problems today. I had a hunch that the culprit was the boot.img which I downloaded--it was corrupt. So I went to OnePlus' site and downloaded the OTA package, extracted the boot.img from that, and flashed it through fastboot. When I rebooted, I was greeted with the beautiful almost old-IOS charging sound, and Wifi!! That boot was quite speedy too!
Hi could you explain how did you reboot your phone i have totally same problem...i tried msm download tool but i cant get my device to show there....could you please tell me how did you put OTA package into phone ? thx
FIXED!
in the end I was able to use MSM Download tool....i just had to manually download Qualcomm drivers so that my phone can be recognized. After that MSM worked and rebooted my phone totally clean. Gosh not gonna root for a while now XD
PS: More fun is that my Windows PC wasn't connected to internet so i had to download everything on my macbook and through USB stick I was bringing all app to Windows.....longest 6 hours of my life

From fastboot, use the volume keys to select Power Off and then press the power button once. Make sure the phone is unplugged while doing this. Then, with the MSM tool ready on your computer, hold down both buttons on your phone and plug in the cable from the phone to the computer. It should automatically boot into EDL mode, and MSM should say Connected.

When I had to do this I didn't connect the device to the network since I don't trust Windows 10 not to open a billion ports up and use my infrastructure for Microsoft's business. Copying to and from a crappy 2.0 drive sucks!
