[Q] Lost USB data connectivity to computers. - LG Revolution

New member here, so please be kind to me
As of this morning after pulling my LG Rev off my wall charger. I go to plug it into my desktop to move some files and what not only to find the phone is not recognizing that I'm hooked to a computer.
Thinking it was a cable issue I swapped between cables and nothing, rebooted, even did the old-battery pull, and still nothing!
However with each cable it acts as if I'm still plugging it into a wall/car charger. Only shows charging and nothing else, the computer doesn't even make a "USB" connected sound, let alone the computer doesn't even see the phone.

Did you reboot the computer and the phone?

I have, let alone tried it out on several computers at home all with the same outcome.
I didn't install any app, other then did a TiB last night prior to putting it on my wall charger(only way to get a good overnight charge vs USB).
I was planning on trying to install the Revolt ROM today. Come to hook it up to my computer this morning, and now this.
I've been having all sorts of odd issues, like the Verizon OTA update doesn't install. Gets about 30% on the updating/unpacking then pops up a {!} and reboots. So at least once a day my phone will reboot for that.
I currently am rooted BTW and i have tried to un-root and even let the update attempt to go, but no avail.
NOTE: I did notice something else just a few min ago, on the stock LG ROM at least. Normally regardless what source Car/wall/usb was being used to charge the phone, It would show both red/green on the LED while charging/charged. Now its only showing green regardless of it being charged/charging.

I think I may just do an exchange from Amazon wireless. Seeing how its within my 30day window yet to do so.

You did change your connection to mass storage when you connected to your computer?

Yeah, played with all the settings and swapping modes.
Just for kicks did a factory reset still nothing.
Curious, is there any way to UN-root w/out the ability to use the USB?

Well I got my new Revo, and it came pre-updated already
And major problems since I've had it, constant reboots, almost always losing connection. WiFi wouldn't stay connected either, even if I'm 5 ft from any router/AP.
And I've tried my best to push back to the pre-update, but no avail!
So I've gotten a hold of Amazon wireless and they are doing an exchange for me, I'm going to jump on board of the HTC TB. Hopefully I'll have a better sailing experience.
BTW, any one want an LG extend battery cheap? lol

usb prob on mine just fixed
omg...I just had a similar problem, except mine popped up on my phone saying that the factory cable is plugged in and can not be used to switch usb modes. I was like...what the frick man...this is the same cable I have always used. I tried alll sorts of crap to no avail. Finally, I reinstalled the lg drivers on my laptop and rebooted both my phone and laptop and voila! It all worked again, using the same factory cable that my phone and laptop just had a so-called problem with. Hope that works for you too...I know how frustrating things can be.

had a very similar issue several days ago. all of a sudden, the phone was no longer recognized. tried everything (different cables, different computers, different operating systems, toggled several different options in settings)......to no avail. had to take it back to best buy....exchanged it for a new revo...everything is good now (including the fact that it was loaded with v4).

[Q] Hero does not connect to computer through USB it only charges

After owning my Hero for my 14 months, my Hero suddenly stopped recognizing when it was plugged into my computer through USB. The phone charged but did not give the option of mounting the phone.
I have tried connecting with recovery (both clockwork & Amon- Ra), through stock rom, Cm6 and Cm7. I wiped, flashed, removed the battery, removed the SD card, tried multiple computers and multiple USB cables.
One other symptom I noticed is that the battery started burning down very quickly. I eliminated any app that was causing this by wiping and flashing to stock with no apps, but the battery kept burning down.
I finally gave up and brought the phone back to a Sprint store and got an insurance replacement.
Now I have had my replacement phone for all of 10 days, and the same thing just happened to me again?
Is this a hardware problem and I have such bad luck that it happened to me again? Or is this something I might have messed up and could fix?
You could try a new sd card.
Yea its me again with the
Modified Hero
Is it doing this with all computers you connect into? and have you used the same USB cord each time?
Mine did the same thing after about 10 months. Mine also lost hboot or any ability to get to recovery. It did still charge though. Sprint swapped it out under the insurance plan
Is it doing this with all computers you connect into? and have you used the same USB cord each time?

I have used multiple computers and multiple USB cables. The Sprint store tested it too and saw the same results.
I just got a new phone under the insurance from Sprint and I want to figure out what could be causing this so it doesn't hurt the new phone.
This might be a little late.
Iw as having the same problem with my Optimus V. When I plugged it into the computer it wasn't reading that it was in a computer,only that it was charging, my computer wasn't event picking up the phones usb connection either. I restored my phone, reinstalled all the LG drivers..still nothing. So I went into my device manager on my computer. Next to one usb port there was a little yellow exclamation point. it said that windows had stopped using that device because there was a problem. So i right clicked, hit disable, right clicked again, hit enable and it worked! Hope this helped.

Weird behavior while using a non-oem usb cable

So I am trying to root my d4 but I wasn't given a stock usb cable. Instead, I am using the usb cable that came with my lg revolution. But when I plug it into my laptop & d4, all of the sudden the phone goes into settings and starts selecting and deselecting settings seemingly at random. Is that something to do with the cable?
Sent from my DROID4 using xda app-developers app
Okay, I figured out what was going on. Here's what happened in case any of you experience the same problem:
It was the cable like I was thinking. Sometimes when I hooked the D4 up to the computer with the LG phone's cable, it caused the phone to bog down (maybe it was busy trying to communicate with the laptop and the cable just wasn't compatible so it kept trying and kept trying, etc.). I'd gone into settings to turn USB debugging on and when I swiped along the screen was when it started to lag. So, the D4 couldn't tell that what I'd done was swipe my finger over the screen to scroll down. Instead, it thought I'd selected everything in the path of the finger swipe. But it reacted so slowly I couldn't tell that's what was going on because I'd swiped again resulting in yet more selections/deselections of settings. And then for 20 seconds after swiping it was still catching up and toggling settings on and off. Rinse and repeat...
I borrowed a Motorola cable from a Droid X2 user and everything went smoothly. My phone was recognized, drivers installed, yadda, yadda, and I'm now rooted!

I think it's actually interference created by an unstable DC charging current that messes with the sensitivity of the touchscreen. I have the same problem with my D4 if I use some of the crappier USB wall chargers. I've found the Apple iPhone / iPad chargers work pretty well and most any USB micro cable seems to work pretty well. it could just be less than stellar DC voltage coming from your laptop. Maybe you were running off of battery in one of those instances or maybe wall power, or maybe you were plugged into a different wall socket or at a different house / place with a different mains electrical feed?
Thanks. That sounds plausible. I was using my laptop on every attempt but I don't remember when I was plugged in and when I wasn't. I'll have to experiment a little and see what happens.

I've now tried it in every combination I could think of...connected to a laptop plugged in/not plugged in to the wall, connecting to a desktop...using each cable in each situation, and using a couple of wall chargers. The only thing that made a difference for me was the cable. The moto usb cable works fine as do both the lg and off-brand wall charger cables I have. The problem only comes about when using the lg usb cable with the d4...then stuff gets freaky. No big deal, though. I can easily avoid that combination. Just found it interesting/weird.

Unable to charge phone or sync with pc (rooted)

Hi everyone, firs of all i want to apologize if this has been answered in some other threads but i did my research and coulndt find any solutions to my problem, that being said, here we go!.
Few days ago i noticed that my phone was dead, I thought it had just run out of battery and plugged it to the power outlet, after 10 mins i realized that it wasnt charging at all and i did a soft reset by keeping the power button pressed and voila!! it came back to life it was charging again so i took it and plugged it into my computer and there is when everything started because my computer wasnt recognizing the phone anymore. I thought that it was just that one time and so i restarted the phone and re plugged it to the computer and this time it not only wasnt recognized by it but it was not charging again and ever since I've been trying all kinds of methods to have the computer recognize the phone (different pc, diferent usb cords, reinstalled drivers, reset phone to factory settings, everything). I did find out though that if i turn the phone off and back on it'll charge and if i do it again, it wont so its like a cycle thing but the being recognized by a pc i havent been able to fix it. Any ideas?
I am running stock ATT 4.2.2 JB rom but rooted.
Thanks in advance.
Did you tried a different charger?

note 5 - USB not recognised and it never fast charge

Hello I have a note 5 - SM-N920C on stock M 6.0.1
about two months the phone stop fast charging and doesn't get recognised by the pc
the thing I tried :-
* try different USB cables ( 2 came with the phone - 2 new once )
* factory rest ( twice with wpie chashe )
* change the charger
I wanted to test other stock Roms but I can't get it recognised by odin .
and I have 2 note 5 all the cables work fine on the other one .
​
I seem to have same issue here.
I have the Note 5 from tmo(SM-N920T)
Baseband - N920TUVU2DPD1
Stock - 6.0.1
You have the exact same issues i've had. I also had issues where when i would have the phone plugged in ( to the wall adapter ) and rebooted it, it would think its a media device like a computer where it could share files and stuff... Also take like 5 hours to charge from 20%
Here I'll make this fix SUPER EASY..
1. Download Package Disabler PRO - I dont think it has to be the pro version but i bought it a long time ago
2. Search for 'power'
3. Disable 'com.sec.app.TransmitPowerService''
4. Reboot
I would add screenshots but as i dont have 10 posts im unable to post screenshots or links to the app in the playstore.
The wife's phone started this Saturday after updating. Also, hers beeps and has the charging blue wave as if she plugged the cable in. While actually charging, it disconnects and starts charging constantly.
The beep and blue wave is normal. The charging and no charging sounds like a faulty cord that's not making good connection
The beep and blue wave happens when she is not plugged in. Phone just sitting there not being charged or touched. We thought at first it was a bad cable, but we've tried several. Even does it on the wireless pad. Therefore I'm not sure it's the port. I think it's software related.
Have you tried safe mode?
Just a warning safe mode reset my wall paper and logged me out of some apps.

Did try safe mode and a factory reset. Sprint store I brought it to tried several cables and another factory reset with no luck so they ordered her a replacement. They weren't too interested in figuring it out. In fact, 3 other people came in with various issues and were just given the number to make an insurance claim without even looking at the phone.
I disabled that apk abd it detects all my fast chargers as fast ones. Where it didn't. If i re-enable it it stops workin
might be hardware issue, Try Wireless charger and see if it charges fast. if it charges good with wireless charger then you have to change you CHARGING PORT.

Had the same exact issue on a refurbished unit . Old note didn't do it, but had to exchange it due to adhesive glue coming up in upper left corner. I did multiple resets and finally went with the option of fresh install as not to import back my apps. It hasn't replicated our issue in the last few hours. I am hoping that takes care of it.
Did you by chance get a random gear VR screen prompting you to download the app and what not? I did and read others had the same issue and only way to get this to stop is to download it and then create an account, reboot and viola it solved it.
Stuff is crazy, love the phone but have had more issues with it over even El cheapo phones....

I got similar problem... now after 10 days I just can not go with this.
my youtube problem.
https://youtu.be/payi2IuJhdI
My NOTE 5 is thinking that is charging all the time. It drives me crazy.
With the USB cable it charges 1 time out of 20 and on a random day. I had to charge it via wireless. It wakes up all the time and can not use UBS.
Strange part is, that I can use my USB micro stick with my root and custom ROM. But that is it. No ODIN, no tranfer files.......
Did everything except change the USB port (it is on it's way). ( that will be my last resort)
ANY THOUGHTS.
I have a feeling that water damage was somewhere in there. (been driving with my bike on a rainy day and it looks like it got a little wet in my upper front pocket.
mine recognises fast charge very randomly. before it happened rarely but now it never shows fast charging with the original cable. the only thing that helped me was ordering a third party cable and using the original ac plug. let me know if that helps to any of you guys!
Ugh. N920a mine started this in March after having it maybe 3months. I called att and told them to send me a new one the other day. Unit arrived this morning. My opinion is its a bad USB port. This imho is the weakest link in Samsung devices-- this POS antiquated USB crap.
The thing would cycle CHARGING -- DISCONNECT, over and over. Wiggling the cord would affect the condition. Fast charge happened 1 out of 20 attempts.
I'll let you know how long the new unit lasts-- my most recent purchase is a wireless charger because, as stated this ***t is bound to happen again.
Unbelievable. My phone was totally fu**d. Than I sad I will fix it my self, so I bought the USB board and waited to get it. In the mean time I used it as normally, just wireless charging and that's it.
But after two weeks, the phone was getting a little better, not fixed, but due to custom ROM and a few tweaks, it did not turn on itself all the time.
But after I played quite a few games, (hitman) the phone did heat up all the time, and that my friends FIXed my problem. NOW the phone works as before the moister get to it.
I have my NOTE 5 back, yee.
SO when you have moister problem - play games.
Hey guys,
I had this exact problem - no more fast charging, no USB OTG or recognized by computer after
upgrade to Marshmallow. Tried multiple cords, different computers (Mac, and Windows), etc.
I sent it in for repair to Samsung and they 'fixed' it and are in the process of shipping it back
I put 'fix' in quotes because the repair tracking says it was solved, but I haven't received it back yet to
test. It should be coming in tomorrow.
Quick charge and USB issues have been fixed! IF you're still under warranty, I'd highly recommend sending it in.

Droid 4 won't turn on, but recognized by computer?

I have a stock Droid 4 with a mugen power extended battery. Last night I got a vibration that felt like a Facebook notification on my Droid 4. I pulled it out of my pocket and tried to turn it on, but the screen remained black. I tried holding the power button to reset it, but there was no response. I tried plugging it into my wall charger that usually works with a usb cable that also usually works, but even after an hour, there were no signs of life. I tried plugging in the cable to my tablet, and it charges just fine. I've used other cables and chargers, still no luck.
I tried plugging in into my laptop with the cable I normally use for charging and my laptop picked up that a device was connected. I looked in My computer to see if I could access the phone internals, but I just saw a drive letter with motocast, and 2 other drive letters that told me to insert disks in to them. The motocast drive letter had what looked like motocast system files, but that was it. I had an SD card in my phone, but no drive letters that came up when I plugged the phone it let me access it. When I went to safely remove it, I saw in the device manager that it correctly identified that a Motorola XT894 had connected to it, and I safely removed. I've tried doing a soft reset, holding the power down+vol down button for 10 secs, but that does nothing. There are no lights at all, not even when I plug/unplug it from the charger.
I'm planning on going to a cell phone repair place today to have them remove and troubleshoot the battery ( I don't have plastic torx and I'm afraid of short circuiting the motherboard)
I feel that there is some hope for fixing the problem or at least data recovery since windows recognized my phone and I could at least get to the motocast folder on it. I do wonder why my phone is able to be recognized by my computer but still show no signs of life otherwise. Any ideas?
I love this phone, but it sucks with this happening around the holiday season.If it can't be fixed, I'd at least like to get my data off it. Please help!!
Is there any way to fix this? Would physically removing and reinstalling the battery work? Do I have any options for file recovery off my phones internal storage, especially since it seems windows recgnizes that my phone is connected?
UPDATE: Got it to power on and boot normally once. Enabled USB debugging when I had the chance.
Got back from the cell phone repair place this morning. He said the battery was definitely bad, drawing zero amps. He also said he was getting weird voltage spikes throughout the board, and I think he said something about the PCMI power management chip being bad and that the phone was done for. I told him that I could plug the phone into the the computer and it recognized it. He said my best bet might be getting a battery off eBay that would power my phone long enough to get everything off of there. I asked if it could also be USB cord related as I tend to have horrible luck with them. He said it could be and that the reason that I was able to have the phone recognized by USB but not charge is due to different pins communicating during USB connection. I'm including these details so you can gauge this guy's expertise. He did go from saying the phone was done to suggesting a new battery/USB cord, and I was able to power it on after using said cord.
I went and bought a new USB cord and plugged it into my inverter I had in my car. To my surprise after a few seconds, the phone was showing the charge screen with the battery at 70%. It still wouldn't boot up so I kept it plugged in for about 5-10 mins. Eventually it did boot up. I immediately went in and enabled usb debugging. All my data was there. For a brief bit the date and time was off, but even that corrected itself. I played a song from my music collection on my SD card to make sure that was OK. The song played, and shortly thereafter it looks like the phone powered back off as it had originally done. I hooked it up to my computer and my PC started installing new hardware, it said something about xt894(my phone) a couple of disk drives and a CD ROM drive, and something about adb. The furthest they got were as unknown devices, so I disconnected them and reconnected them a couple of times, eventually the install icon went away. It still recognizes the phone and even recognizes there is a storage device with the phone in the device manager menu, but it still says "please insert a disc into drive (letter)" The drive with just motocast is still there, and I think there was another CD ROM that was recognized, said to insert a disc same as the drives. I threw it on my wall charger for a few minutes, but it still wasn't powering on. I then realized that charging it could exacerbate the voltage spikes the guy was talking about, and I didn't want to risk it especially after seeing all my data there, so I unplugged it.
I do have the battery that the extended battery replaced. It had to be pretty much tied to a charger, but it did work if only for less than half an hour. So there is the option of using that to temporarily power the phone.
My new questions are:
Am I at risk of further board damage if I charge/power on the phone? What about charging the degraded but functioning battery?
Now that I know I have USB debugging enabled and my computer still recognizes my phone, how do I go about backing up the contents of my internal storage?
Could this all be effectively solved by just getting a new battery? What about what he was saying with the weird voltage spikes and PCMI chip?

Have you tried it without the extended battery. That could be the culprit of all this going on. If your original battery is bad get a new one and charge it. I had the same problem with a battery till I bought a new oem battery. After I charged my Battery I had to go to fastboot to get device to boot with a fastboot cable. Then while connected to that cable I backed up my contacts. Then while still connected to fastboot cable I flashed stock firmware and started all over again havnt had a problem since.
I'm waiting on an OEM battery to arrive. I was able to save everything off my SD card that was in the phone, so I am increasingly hopeful. Do you have to go into fastboot if your phone is stock? What is fastboot even?

AP fastboot mode is where where you flash stock while connected to rsd lite via usb or fastboot cable. It is part of bootloader. You hold down all three buttons to get to boot menu scroll down to ap fastboot then hit the vol. up button then connect to computer after you have rsd lite active. then flash stock firmware. If you get a battery that doesn't charge have them send you an other one that has happened to me a few times but not many. Remember when you scroll in boot menu you only have a few seconds to pic what you want to do or the device will try to boot.
The OEM battery I ordered finally came yesterday (no thanks to USPS). I tried multiple chargers and outlets with a good cable, and still nothing. I have another non-OEM battery arriving tomorrow, hopefully this one was just a D.O.A battery.

It was probully a dead battery. It sat for to long. If you had a fastboot cable cable you wouldn't need a battery to flash it in rsd lite or just to see if it would boot. There was this one time I had to order 3 battery's just to get one that worked. Sometimes they been sitting for to long being the device was made in 2012.

So your saying if I had a FastBoot cable I could boot my phone without a battery in the phone? Would it wipe my internal data/OD?
Update: I have had a BIN-TEK battery charging for several hours, still nothing. Good cord and charger too. The only other options I have is the extended battery that crapped out on me but powered on briefly, or the puffed out factory battery it replaced. Things are looking bleak
OK

It is so you you can get to fastboot mode so you can flash. It is usable with a low battery or no battery at all. When you first connect it to computer it will automatically start booting. Here is a link for one: https://www.amazon.com/gp/aw/d/B00K...boot+cable&dpPl=1&dpID=41ep3FoxgHL&ref=plSrch
If it boots to your ROM when you first connect it then you have battery problem. If it does not boot to rom then you should leave it connected and flash stock firmware from fastboot mode witch you will need rsd lite to flash. If it boots after that then it us just a battery problem. If nothing happens then you probully need a new droid 4. Remember once you disconnect fastboot cable device will go off. So don't disconnect until you are done with everything being that you don't have a good battery.
I have a fastboot cable now. Haven't tried anything yet but I plan to today. I've looked around XDA for firmware If I need to flash stock firmware, I found several versions for the Droid 4 here:https://forum.xda-developers.com/droid-4/general/droid-4-xt894-firmware-mirrors-2015-t3004048 how do I know which firmware is correct?
Also, am I good to disconnect the fastboot cable from the PC as long as I am NOT in the process of flashing firmware?
I have ADB debugging enabled on my phone, and last I checked my computer recognized my phone, just couldn't access internal files on my phone. (Had "Please insert disk into drive x" message) Any options there?

4.1.2 - VRZ_XT894_9.8.2O-72_VZW-18-8_CFC.xml.zip just in case you need to flash. just connect cable and see if device boots if not flash the firmware with rsd lite. never umplug cable unless you want the device off because when cable is is pulled the device will go off.
I connected the fastboot cable without a battery in the phone. Held power button, computer detected it. Said it had found an XT894 and Motorola Network drivers or something like that. Said my installed hardware was ready to use. Noticed in device manager and network connections that Motorola USB networking driver #3 was installed. Under My computer, didn't see any new hard drives. I have RSD lite and the firmware you told me to get. RSD light shows my phone model, imei, software, ect and says that I am connected. But there has been no activity on my phone's screen. No Motorola logo, no menu's, nothing. I would feel more comfortable if I could pull my data off before I flash the phone as I have read horror stories of flashing gone wrong. Is there some way I can access my phone's memory since the computer recognizes it and backup my files before I flash?

When the device is off just connect the device to your machine and it will boot to your rom thats it. It will do it automatically. No need turn it on yourself. If it wont boot then something is wrong with the rom. If that happens and you were running a custom rom and not stock go to safe strap if you had it installed and use that to boot back into stock rom slot. Now you have two scenarios you can use. Do the first one I wrote first. If you Have safestrap installed then do that if it wont boot. Dont forget to have to have the drivers installed for the device on your windows machine. On windows based systems you have to have the drivers installed installed before using rsd lite. Just in case I forgot to mention that.
My ROM and phone is stock
Another update: I'm trying to use ADB to backup my phones files before I flash. Here is what happened:
Sorry for the lack of updates, been busy. Anyways, I got adb installed, plugged in my phone, did adb>devices, didn't show up.I got the newest version of Motorola device managermanager and had it update. Plugged in my phone again, computer said it found an XT894 and Motorola USB networking device, told me to restart my computer. Restarted, tried to see if adb detected it, nothing. It shows up in my device manager under networking devices, it even says the location is an XT894. But adb still doesn't see it.
The weird part is that RSD can see my phone too along with device manager. I'm planning on flashing to see if I can unbrick my phone, however I want to try and backup my files on there just in case the flash wipes my phone.
Is there a way I can have my computer recognize my phone as a drive instead of a networking device so I can get my files?
Is there any way to get my data off my phone before I flash?

The only thing I can think of at the moment is safestrap If you had it installed before you bricked the device then you could try booting to safestrap and then mount device in safestrap and copy and paste all your internel sd stuff you want to keep. If you did not have safestrap installed then make sure you have correct drivers for device installed and try the adb command again and see if it reads. I'v been in your situation thats why once a month I now back new stuff up. When I had the s3 I bricked during bootloader unlock. Took me three days with an image file to get it to boot. Then I reflashed the stock and didnt need the image file any more. That was long time ago. i learned to back my stuff up after that. I just thought I would mention that just so you could have a food for thought. Also data will be lost is another reason to back stuff up.
