Hi
I have this problem with Lg G5
When i connect pc with usb type c cable to phone ... phone goes immediately to restart and is trying to install new firmware update , where it freeze .... only solution is to remove battery to restart it ..
I have the latest FW update thru wifi ,so no new updates here ..
I have android 7.0 software version.: V20h-231-02
I tried to change in developer mode usb setting to Charge only ,but it is not helping ...
Thanks for any help
Robert
Silly question perhaps, have you tried a different USB cable? Or a different PC? Does it restart when you use a wall charger?
It does not restart when i`m using wall charger ... and with second cable it is all ok .... So you are suggesting cable can awake firmware update ?
At first glance, I understand that your G5 would try to download updates when plugged (just like it does with app updates).
Problem is: you said it doesn't do it when plugged to an outlet and your description suggests it's not downloading an update but trying to install an already downloaded one.
Any idea which update this is? Can you check and see if it's firmware, software or native apps (LG app updates)?
If I were you I would go through all the sections in your phone's settings menu where you can check for updates of any kind, and see if there's an update ready to download or ready to install.
I had the same issue.
Enable Developer mode, and uncheck "Automatic system updates" from the Developer Options. That'll take care of it.

This partially worked for me. If I connect it to my PC via USB, it'll still reboot to the firmware screen, but if you leave the cable in there, take out the battery and restart it, then it'll properly connect and allow file transfers. This is the Verizon version.

First of all I am a big-Noob.
My LG optimus one P-500 is in stock ROM.
My Problem :-
Earlier USB was working fine but now
when I plug it in to the AC Adapter it charges OK but when I plug it in to the USB after that it only charges and neither the Phone nor the PC recognizes the USB data connection.
I have tried
1) Power off the phone and remove the battery for a couple of seconds and power it back up, after doing this the USB does not connects. Not even recognised by PC or Phone
2) Device manager also does not detect anything.
3) Uninstalled modem driver and reinstalled USB driver but no result.
Please help
Thanks in advance
Cheers
Request again
Dear mates
I have really very high respect for the forum so please help me out.
ThanQ
Cheers
This happened to me twice before. I had to send it to LG's Service Center because I saw no way of fixing it since the computer wouldnt know what to do with it...
If you have custom recovery installed, you might be able to flash an original ROM over it. This wasn't an option for me before and it seemed like the only way to fix my phone. Don't take my word for it though. Try for the service center first if possible...
Did you try going to settings and choosing Mass Storage only?
Also, change the USB port of the cable with which you connect your phone (plug the cable in another one - try this with all ports if it doesn't work the first time)...
Before going to any service, do a backup and Factory Reset your device, then try again...
Oh, and disable LG modem from Device Manager after installing the USB drivers.
USB not getting detected
I am trying in choosing Mass Storage only.
"Also, change the USB port of the cable with which you connect your phone (plug the cable in another one - try this with all ports if it doesn't work the first time)..."
Not helping either
Disabled LG modem from Device Manager after installing the USB drivers.
No use
Before going to any service, do a backup and Factory Reset your device, then try again...
I will try this definitely but going to service means 3-4 days without phone . really very scary .
thanks mate
anymore help
Okay , I did face this problem before and I did about hundreds of advice from my friends but this is the step that works.
I discovered that this happens when you do crazy **** on your sd card with applications such as titanium backup or root explorer. Curiousity kills the cat.
Firstly you need:
1) Usb Card Reader [Of course which suits with your sdcard]
2) Computer
Firstly, you want to dismount the sdcard from your phone and mount it to the USB Card Reader.
Connect the Usb Card Reader to your Computer.
You should be able to gain entry to the sdcard
Next,clear everything on your sd card then place your sd card on your phone back and do a factory reset. If you don't do a factory reset then you must do it all over again if you decided to connect the usb to the phone. After reset-ing the phone , try to connect your phone to the computer. Congratulations.
Note: This works for me but it doesn't meant that it will work for you , but I think that this is worth the try.

Ur phone charges through usb that means your phone usb port/usb cable is ok. Do this :
Uninstall the drivers, restart the pc and try connecting the phone again. Remember not to install the drivers again. Win7 save a dump of old drivers and i think it will auto detect it. Post results here.

Got exactly the same situation with USB(on different PCs) and also Emergency mode on every reboot(taking battery out for about an hour helps).
Did SD wipe though not sure about factory reset afterwards, gotta try it one more time...

I have tried uninstalling driver and just plugging in with USB but still neither PC nor phone detects USB connection.
I have tried it on Win7, Win Vista and WinXP.
respected mates please help me.
I am on transfer in June so don't want to take chance with Service centre as of Now.

Are you sure you are having the latest driver?
try this:
Code:
csmg.lgmobile.com:9002/client/app/B2CAppSetup.exe
install it,
(you may have to choose language from the last tab, 1st or 2nd option)
and choose P500 from "driver installation"
I didnt experience this issue but if i cant help im sorry.

Try another cable.

None of the above methods worked on mine as well - same results on different cable(pc/os).
Will try to flash rooted original firmware via custom recovery, del custome recovery and root and send it to service.
Hey
In Android, when you plug in via USB your phone to your PC, in the notification bar, a option is given to show the device as a USB drive. I dont get that option any more and I dont see anywhere to enable it or select it.
How can I do this?
This might be stupid question, but did you try to restart phone and pc?

Yes.
Maybe there is a app for Android to launch itself into storage mode, thinking a USB cable is connected to it and at the same time a PC? Its just strange.
Ive also tried with other USB cables still nothing.
Do you have fast charged enabled? If yes, disable it

you must enable usb debugging or there could be an error with your usb...

How do I know if I have fast charge enabled?
Also in recovery, as you know, there is a option to enable USB storage which also makes your phone's SD card be viewable in explorer. That doesnt work either.
Im starting to think it is a kernel problem.
Try Flashing the new Clock Work Mod Recovery, I found it in the One X forums and I tried it it worked and it might work for you let me just find it

Why don't you try what he said, just do this steps.
go to Settings > Applications > Development > find the USB Debugging Mode over there and check whether it is enabled or not.
USB Debugging Mode can be used to copy data between your computer and your device, install applications on your device without notification.
and of course, without java installed on your PC Desktop or Laptop, connectivity between your android phone and PC would create some problems, be sure to update your Java if you have already installed.
And to clarify the issue of fast charger mode. I think it's not related to your problem since you cannot understand what fast charger mode and how to do it in the first place, am I right?. There's a procedure on how to do a fast charger mod and if you want a proof, visit this link which can be found here in XDA, Charger mod, how to USB fast charge.
Hope it helps

Hello Everyone
I am putting my problem in this general section with the hope to ask for help to more people compared to the Mate 8 section where not a lot of people go these days.
Since a while I am not able to connect my phone to a laptop. If I connect it to a laptop it just starts charging but nothing else. I have tried everything like:
Changing Cables (tried more than 5. I dont have the original anymore)
Changing Laptops
Changing the USB port of the phone itself
Updating Drivers
Installing Hisuite (current version 5.0.3.300)
Restore phone to factory settings
Complete formatting
Updating to the latest version (Current version Nxt-L29C185B582)
Changing the USB debugging/ Connection (MTP/PTP/etc)
And what not
The problem is, it doesnt get detected on the computer and cant connect to adb as well. All I want is to unlock bootloader and Install TWRP and Magisk. I have the unlock bootloader code but no way to unlock it since I cant connect.
Can anyone help me in fixing this stupid problem ? It is getting frustrating. If there is a hardware issue, what part needs to be replaced? Any help would be appreciated.

Go to the Settings of your phone---> About phone----> Build number tap this 7 to 8 times-----> Developers option is enabled----> back to settings ----> go to developers option ----> enable USB debugging.
When you connect to the phone to the laptop you will find an icon on top of the screen of your phone with a USB mark "like a trident", pull down the top menu and find the USB connection tab, (like changing the sim card if you intend to call through a specific card) e.g quoted, double tap the USB tab to obtain options ---> 3 options 1) MTP 2)PTP 3) USB charging only----> select the first option MTP (Media transfer protocol).
Now connect to the laptop you will find exclamation marks in the device manager of your laptop. Load the appropriate drivers on your computer and viola! this will establish connection with the device you are having. if you find difficulty in installing USB drivers, search the thread "Attempt to load USB drivers for Micromax E484 on win XP is a fiasco" in this forum.

What is the model and OS version of the device and the model and OS version of the computer? According to your symptoms your phone appears to be in option 3) USB charging only. The phone will not be detected by your laptop or the like(Computer) in this mode. Merely remains in a charging state. Are you certain the option 1) is picked MTP? If the phone is not detected there appears to be some hardware failure, try another USB port to connect to the laptop. if all else fail a service technician will pinpoint the fault. It may perhaps be a data transmission failure of the devices port to the interior of the phone. This is merely an assumption.
best remedy would be a service technician.
Hope this helps

I have tried changing the usb charging only to all possible options but it still is the same. I tested in Linux and when I connect the phone nothing shows up in the logs. It's like it's not being connected . I have tried changing the usb port itself from the phone but it remained the same.. can the flex cable be a problem ? Mate series was never launched in India so I don't have any help from the service centre. I have to order the spare from eBay.com so there is no qualified technician who can help.. that's why I have to fix it myself somehow..
Thank you for your help

I quite doubt the cable will be the culprit as your device charges the battery while in an established connection with the laptop. As you state the phone USB port was replaced, it could be a some glitch before the USB port in the device where there is an interruption in the data transmission signal that cannot be detected by your laptop.
Could you boot your device, computer and connect the two and take a snapshot of your device (whilst connected to the laptop) and paste the same in the forum?
Perhaps visual cue could be better at dealing such mishaps.

Your USB trident icon is not indicated on the device, If you were to receive power from the laptop the trident would be displayed on top of the screen, even for charging the battery. The power source for your device appears to from other than the laptop.
I have pasted my device after connecting to the computer and the second icon from the top left is the USB Trident icon indicating connection with my laptop. Have taken the snapshot of the menu that I was describing .
I strongly feel you have a hardware failure rather than a simple fix and would require the help of a technician (ordinary if professional is unavailable). Am skeptic you could mend that on your own unless you are proficient in electronics. This mishap is not due to flashing wrongly too, unless you have changed the stock ROM with some custom ROM which has some bug that affect the USB alone.
Take the assistance of a technician whether professional or less is my counsel

I can do basic electronics but the if the problem lies in Mobo .. then nothing can be done .. as I don't have the spares available in India. But I would hate to lose this phone as it was a perfect fit for my needs

If you do not have spares is best left alone rather than tampering with it and rendering the device useless if any untoward incidents tends to occur.
But I would hate to lose this phone as it was a perfect fit for my needs
Send to the vendor directly if you have warranty for the device stating its complaints or request your relative or friends who live in the area where you bought your phone to hand it to the vendor or service technician and bear its expenses

Is there a way to unlock bootloader somehow without connecting to usb ? That would also solve the purpose.. I want to root it for some of the things to work and with the latest upgrade to latest version I lost the unlocked bootloader and root.. if somehow I can unlock and root .. I should be fine without the usb connection to computer.. but I have ran out of ways
Does Kingroot work for you?
I mean did u try it or u just want magisk?
If u didn't, kingroot may be able to root ur device and unlock ur bootloader, then u can flash TWRP using rasher.. & make a backup BTW...
After that, try using the adb sideload in TWRP to test ur connection with ur computer.
TWRP for ur device : (q.gs/DxuAH)
There is a way to unlock bootloader without USB via developers option.
Go to settings-----> About phone-----> Build number ( Tap this option around 7 or 8 times) till developers option is enabled------> go back to settings-----> developers option-----> OEM unlock option (Enable this option) to unlock the bootloader.

There is no FRP unlock, to circumvent FRP you need to factory reset or flash your firmware. The above quotation was to unlock the boot loader as you cannot access through your computer. Your sole option to unlock boot loader was through the above directions.
Moreover, King root application never ask for boot loader to be unlocked. Although a little unstable this is the initial program to root any device. Once you have the TWRP setup then you could switch to Super Su etc. according to your preference.
Could you paste your developers option snapshot here...

Hi guys,up front I apologize for my English.I need help with my phone S6 edge,fast charging is not working and as I understood lot of other people have the same problem(charging takes 6h 0%-100%).I also noticed the problem happened to others after updating to Nougat 7.0.I had the plan to downgrade my phone to older version of android but...as I connected my phone to PC it says Unknown USB(so ODIN can't recognize my phone) and in device manager my phone is detected as Unknown USB device(Device Descriptor Request Failed).In settings software update says I have the latest software installed and I have no option to update to newer edition.I tried factory reset,wipe cache,tested charging in safe mode,tried 2 differen't charging flex assemblys in my phone,differen't cables and charging adapters,differen't USB ports on PC,multiple samsung USB drivers...that go along with smart Switch,Kies,Kies 3...fast charging is enabeled in settings,tried turning on USB debugging,setting device as MTP in developer options...god knows what I haven't tried.Is there known problem and perhaps solution...or someone who can suggest more troubleshooting methods.I am able to open and fully disassemble the phone to check hardware if someone suggests me to check on some hardware...any ideas PLS?
Hello everybody,
as the title suggests my P20 Lite doesn't get recognized by PC. When I plug in the cable it only get charged. I've tried several ways to solve the problem but no one of them worked. What I did is:
- Used a different cable
- Used another operating system on my pc (Linux)
- Used different laptop
- Used differents usb ports
- I checked if everything was okay in developers setting: USB debug activated, Always notify for usb connections acitvated, USB configuration set to MTP
- I've gone into the "hidden menu" (dialing the code *#*#2846579#*#*), and selected differents USB Port Settings
Useless to say that HiSuite does not detect my phone, and neither does ADB. Also in windows device management it does not appear, netiher as uknown device. When i plug in the cable into the usb port of my pc, I dont get any notification on my smartphone (the one that let me choose if i want to transfer files etc..).
My phone informations are:
- Model: ANE-LX1
- Build Number: 9.1.0.401(C432E13R1P7)
Bootloader is unlocked.
In the last days it got updated to the latest version, so I've lost root permissions.
Thanks everyone that will help me =)
Hi,
on older Hisuite versions, it sometimes helped to connect the phone to the PC and reboot both together.
You can also try to reinstall FW via eRecovery & wifi.

I'm not sure, I didn't do it at EMUI 9.1. Don't have an unlock code?
The problem was the phone's usb connector, I'm gonna replace it =)
