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

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.

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.

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

@riahc3
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

Phone:
Tmobile T959 aka Samsung Vibrant
It is on stock Froyo 2.2
It has the 3E recovery.
I tried on 2 computers but I can NOT connect via USB it gives me USB malfunction error. The phone does charge. I can put it into download mode vie the 3 finger trick. When you connect it does give you the option to click the green Android icon Connect to USB. So it is talking to the computer, the usb is not totally dead.
Problem:
I need to root this phone. I can not use 1 click or anything else because I think there is a problem with the USB port. I can get files onto the phone via wifi or using the external sd card.
I tried using the update.zip file BUT because I am on the 3E recovery it will say signature failed. I can not run the install.bat to get it back to 2E recovery. I can not use ODIN because the Windows will not detect the phone properly.
What workaround can I use to root this phone? How would I use terminal on the phone?
HOW WOULD YOU ROOT THE PHONE IF YOUR USB PORT WAS "broken"?
THANKS for helping!
As far as I'm aware, you can't root your phone without the USB port working as most (if not all) root methods send their commands and files through ADB. Your pretty much stuck, unless your phone is under warranty. In that case, just go to your carrier and see if they'll give you a replacement device.

It's out of warranty
I think there may be a way to do it via terminal emulator on the phone.
If this is possible, can someone please post how to do it.
anyone with a work around?
damn!
Am I stuck or does anyone have a way for me to root this phone without the using the USB connection (USB does charge, It will know when you connect to the pc for USB storage BUT windows will say not recognized. I tried it on 4 other pc's same results. I think something is wrong with the OS of the phone. I think the previous owner tried to update with Kies and it messed up the phone. The phone does boot and works.

How do I root this phone WITHOUT the USB port?
There has to be a way!
Can you determinate VID&PID of phone?
I can get into the device with airdroid and see the system files.
Which files do I need (or which apps) and where do I copy them manually to get it rooted?

Is there not a device forum where you might could get some better information? My thinking is, a lot of the people (or most of the people) who may know some workarounds can probably help, but they don't check this section very often or at all.
Even if there's not a section for that model, I'm thinking there's probably one quite similar. Also a lot of times, a big portion of the userbase of one phone, will migrate to the same model when they upgrade.
Just throwing out some ideas in case that's helpful. My only advice on the problem itself is that I would look further into the driver issue. I've helped several people with very similar issues that we finally were able to correct.
Have you tried to ADB the device just to pull the serial? With USB debugging enabled. Have you installed the SDK and tried the naked drivers? There's some things to pursue possibly so you can have more information for the person who helps you get things straightened out.
Hi guys,
I'm new to this forum. I've got a Samsung i777 on android 2.3.6 kernel 2.6.35.7 build number gingerbread.uckk6
I've recently bought this phone off ebay
My phone does not get detected by windows 7 or Macbook. I've tried changing the USB flex cable with I9100 v2.3 but still no luck.
When I connect USB port it beeps and shows mtp-initialization/mtp-connected on the phone but it is not shown on windows. It says USB cannot recognise the device. I've got a s3 and ideos x3 both of them are detected.
I've installed kies 3 on my laptop.
I had to swtich off the wifi on the phone because it consumes a lot of battery, I think it is because of the android version I'm using!
I want to root the phone and unlock it!!
Any help is appreciated!

I'm guessing the problem is the Samsung drivers you have installed for the s3. Try uninstalling those and installing the correct drivers for s2.

You most likely need a new cable. Happened to me once! Could be the drivers but I HIGHLY recommend just trying a new USB cable.
Thank you guys for all your help really appreciate it!
I have tried all the steps mentioned above tried to uninstall all the previous drivers I had and installed the new driver as mentioned in the above link but no luck
I tried it on a friends computer with a different cable still it shows the USB device is not recognised!!

Did you install another ROM? It might help to Wipe system, Data, ETC! it appears to be a software problem. Or at least my guess is the ROM your using.
The Galaxy phones all use the same USB drivers whether it's an S2, S3, S4, etc., so if the installed drivers were working for your S3, it's unlikely to be a driver issue.
Can you boot it into download mode? If you happen to have a USB jig, that's the easiest. Otherwise, power off the phone, unplug the USB cable, hold Vol +/Vol-, then plug in the USB cable. It should go into ODIN download mode. See if Windows detects the phone that way. If so, it very well could be something weird with the OS installed (although it appears to be stock).
If you can get into download mode, you can flash a stock kernel to make sure you are starting fresh. A good file repository is found here. I recommend the stock UCKH7 image I777_UCKH7_OCD_No_BL.7z (you'll also get root).
And yes, the UCKK6 release had a serious bug related to the wifi that could drain your battery. Best to go with UCKH7.
You could also download an app that allows you to enter download mode.

I was able to boot to download mode by holding the vol +/- key and then plugging in the USB cable but there is no movement from the computer it doesn't make a sound nor does it detect. I tried restarting the phone then I get a notification on windows that USB device not recognised!
Yes I guess this rom is useless, if the wifi is switched on then battery would not even last 6 hrs!

Are you saying to get a balloon notification in the tray that says the USB device is not recognized? A possible reason for that is a faulty USB cable or USB port (funny enough, I actually got that message last night when I was playing around with my Captivate, and switching USB ports made it work). I know you said you've tried other computers an another USB cable, but that's about my only idea. Maybe there's some debris inside the connector that's messing up the connection.
When you say you changed the "USB flex cable", are you talking about the internal connector and board inside the phone? If so, perhaps the I777 connector board is actually a little different than the I9100 board and causing a compatibility issue.
The bug in UCKK6 related to wifi didn't affect everybody, but it definitely affected a lot of people (based upon reports here).

If you have an SD card, you can download another ROM on that SD card from your computer and then you can install custom recovery (CWM) and then install the ROM from SD card.

First ill run you through the problem I had. Just for reference did you use Mr. Cooks script before flashing Cyanogenmod 11? One of his scripts for cleaning before flashing, actually deletes a certain file, not to keen on which one. What it results in though is not being able to flash OF ROMS and some certain custom ROMS! So id recommend alliance's ROM! As for the "Getting the ROM on your device, you could put the ROM on your SD though recovery "Mount and storage/Mount mass storage/" or just use a micro sd card adapter and move it on there that way.
Thanks for your reply. Would you mind sending me the link on how to do that step by step as mentioned I'm new to Samsung phones and also this forum.

What state is your phone currently in? Is it still not detected by the computer? You are still on 2.3.6, correct?
If it's still not being detected by your computer, I'm not sure if you can flash anything needed using the stock recovery. I know that when I flashed stock JB, I was able to boot into stock recovery and directly apply the standard CWM update file here. It will give boot into a temporary CWM that should allow you to flash other ZIP files (like a ROM), although I had trouble doing that (so I ended up flashing the AJK_v4.9_NoSwap.zip kernel using the MobileOdin android app, which gave a permanent CWM recovery).
I'm not sure if this same process works with the 2.3.6 recovery. However, in order to get the stock recovery to see the internal SD card, I had to run adb shell commands to mount the partition (meaning I had to have a working connection from the computer).
Solved!!!
HI Guys,
Many many thanks for all your responses!
I have changed the USB flex cable again to an older version v2.2 and my phone is currently being detected by kies! So relieved thanks a lot for all your help..now the rooting begins!!:laugh:
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.

Nope. Doesnt happen
When i connect with the laptop, my laptop doesnt even make that sound for the connection.
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..

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.

Yes of course. It is connected to a computer now. You can see it getting charged but that's about it

Can it be something because of some wrong flash ? This problem has survived through 2 versions and 1 system upgrade through firmware finder .. and a complete format

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
Thank you

I did flash a different rom .. but then back to stock recently.
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

Then the question of wrong flash or ROM issue does not arise

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...

Connect your phone to your computer or laptop, a trident icon appears on your phone notification area, pull down the notifications and identify the notice as USB connection, tap twice you willk be provided with options.
and i want back to orignal system
and i want know how download orignal system (from Huawei web site) to my phone
My phone was Micromax and I am not aware of your phone's firmware, try and google or search the Xda developers forum under your phones model number for the original firmware.
can any one help me how
or how can fixed this problem
and i have other problem
when i try to boot to TWRP phone stay on " your device is booting now..."
Your phone has not installed TWRP duly, therefore it boots straight to the system. Search again in this XDA forum, with your pnone name and model number to obtain instructions
so any one can help me how reinstall TWRP without PC or why this problem ??
