I'm pretty sure that the USB port on my phone has gone bad, but in a strange way. When plugged in, Windows device manager shows an Unknown Device. Looking around the Internet, this or similar problems seem to have happened to quite a few people, but none of the suggested solutions have worked for me. I have tried 2 different cables on 3 different PCs, even one with a fresh install of Windows. I have tried my default ROM of CM7 RC2 and nightly 21 as well as warm 2.2. Even in recovery or fastboot, it still is not recognized. I have uninstalled and reinstalled the newest HTC sync for USB drivers. Even when I manually pick the drivers in device manager, Windows tells me the drivers are not appropriate for my device. ADB devices does not show anything because the phone is not recognized, and the phone itself does not give me any connection options when plugged in, though it will charge. This seems to have have started happening when I used some compressed air in the HDMI port to clean it out for HDMwIn. Maybe something got knocked loose in the usb port.
What do you guys think? Did I kill it/is it dead? If so, will Sprint likely help me if I revert to stock and take it in?

Absolutely. Unroot, flash a stock rom, then take it to a sprint repair center. Your phone has a one year warranty for things just like this
My phone used to do the same thing. Actually... I've had 3 different EVOs do it, but only on my Windows 7 laptop. It works fine for other computers. It started working randomly one day & now it's fine.
Were all three of those computers Windows 7?
Unfortunately no. Two were 7, one was a totally clean install of XP. Either way, totally stock now with s-on. Back to Sprint I go after work.
Ok,
For starters, I am a bit new to the ROM/Flashing gig, so it might come as no surprise that I have somehow managed to foul up my phone in the process. I was attempting to flash a new ROM to the Epic and, while using Odin, the process failed. Now, when I go to power the phone on, it gives me an image of a phone connected to a computer by a dotted line with a caution symbol in between. The phone will still boot into Download mode, but it will not communicate with Odin anymore, so I am unable to re-flash the phone. Odin detects the phone and begins the process but stalls out at Initialization. The longest I have left it there was for two hours after trying all of the different mentioned intervals in other threads.
My question: Is there anything else I can do or do I just need to take my phone to Sprint and subject myself to their mercy?
Thanks guys! I ended up using a non-stock cable (One from an Amazon Kindle, actually), as suggested, with Odin and it was back before I could question whether it was working or not. You guys are amazing, I really can't thank you enough!
Take the battery out then try it. Also take out the battery and remove the sd card. one of those 2 methods should work
I had the same issue last month.
Just change your Data Cable.
The stock data cable is of no good.
Use original BlackBerry Micro USB data cable... my phone was immediately detected by the computer when I used BlackBerry Micro USB data cable.

You don't need to take out the sd card but do remove the battery and put it back in and get a non-samsung usb cable. You're phone's not bricked so don't worry. Also, if you're doing this on a laptop try a desktop computer because there have been issues with it not working on laptops. For the PDA file, does it have '. md5' at the end of it?

Hello everyone!
So every month when Google releases their security updates, I usually flash-all with the "-w" intact. I just like to get a fresh start once a month and don't mind setting a few things up again.
One strange thing I noticed is USB file transfer doesn't work as intended once I flash-all and get back into the OS.
When I connect my Pixel 2 XL to my iMac, the connection is constantly disconnecting and reconnecting every second.
I use an app called "Handshaker" for file transfers, and my device in this app shows up and disappears every second. Transfer speeds are also about half the speed they normally are as well.
Thinking it could be the third-party app Handshaker itself, I went into Terminal and typed "adb devices" to see if my device shows up. One second it will, another it won't. "adb push" will also fail halfway. My USB debugging notification also appears and disappears every second or so as well, so that tells me it isn't the Handshaker file transfer app.
Sometimes it will stay connected for a couple of minutes and then will disconnect. This is extremely frustrating as I'm basically praying files transfer before the device disconnects lol.
I am aware USB cables and the Pixel 2 XL don't get along very well, and I have tried a couple different ones with no luck.
The strange part is, after a day or so, (maybe once the OS "settles in"?) File transfer is back to being rock solid, and transfer speeds go back to being blazing fast again.
Apart from trying different cables, I've tried this on a couple different monthly updates (as the issue has been ongoing for some time now). I've also tried custom kernels and ROMs to see if that helps, with no luck.
The only "fix" is just to wait a day or two and try again (which always works). It's only when I try transferring files immediately after flashing-all.
Simply waiting, although, is technically a fix, it's still very strange and doesn't seem normal. I'd like to hear from anyone else who's experienced this and can explain what's going on.
Sorry for the lengthy explanation but I like to be thorough so it helps you guys help me better
Thanks in advance!
Bump
Many people are reporting various USB issues everywhere with the Pixel 2 XL. Mine isn't even recognized by Windows anymore, and ADB now doesn't work at all...
One day it works, the next day it doesn't anymore
On mine ADB works fine but when I switch the usb settings over to file transfer my laptop doesn't recognize the phone. Drivers are installed properly, tried many usb cables, usb ports, but file transfer doesn't work. Thank God I have good internet connection, so I have a full backup of the whole device on my Google drive. ?? However I didn't need to reflash the phone just yet. I'm still new in the game with this phone. ? No mistakes have been made... Well, not yet... ?
Interesting, seems like (from what I know) I'm the only person who has USB issues right after flashing factory images and no issues otherwise.
That's the part that has me scratching my head the most, because I don't make any changes, I just wait it out and everything starts working perfectly fine again :/
I ran into this problem while trying to do the WTF Bootloader unlock and Root method, as well as the Frankenstein phone...All the steps should work, except I can't even get the thing to allow itself to be detected by my computer.
I have read others with the VS996 who have done the WTF / Frankenphone methods without this issue.
I have plugged it in to the computer as I have with Android phones forever; it says "Charging" and gives no option to switch to MTP/File Transfer etc... I also go into the Developer Options to try and change this, I tap the setting that would usually allow you to switch it, and it opens no menu and acts as if there isn't one to be accessed. I've tried my Win7 and Win10 machines - same results each time. Also does not allow me to change USB mode while unplugged, or even enter download mode! I am using the USB cable that came with the phone, and have also tried other cables. I've cleaned the port on the phone, tried all USB ports on BOTH computers - still nothing. I've ever master reset the thing hoping it was a glitch , but it still will not let me change it out of "Charging" or even act like there's the ability to do so.
Did Verizon lock these things down so hard that you just can't use them like normal Android phones?
I have searched to an exhausting extent, I'm out of ideas... I don't use Verizon, so I really need to figure this out so it doesn't keep thinking it's still being used on the Verizon network. My service works, but it constantly says the SIM is not a Verizon SIM, and won't provision certain services (such as Emergency Calling) ... HELP!

No, Verizon hasn't locked this down.
You said you've already Master Reset your phone, so that's very strange.
I know you tried different computers/different cables/different ports -- but the only thing I can suggest is to try other different computers.
Plenty of VS996 owners on here have Frankenstein their phones. Some then reverted back to VS996 TWRP flashable zip, after bootloader unlock and root, to regain Verizon VoLTE as they are Verizon customers. But no one has had any trouble with USB connections.

if you are not using Verizon, you need to Frankenstein your phone to US998 or H933 firmware. For bootloader unlock and root, you need US998 firmware.

1) I know you tried different computers, but other different computers.
2) Since either Frankenstein or WTF bootloader unlock is going to re-set your phone anyway, go ahead and do that now PRE-EMPTIVELY. Maybe going back to factory defaults will fix something.

I've factory reset. The problem is, it won't let me switch from Charging mode to File Transfer / MTP mode. It doesn't detect the computer and the computer doesn't detect it - doesn't give an option to switch USB mode, etc... See attached screenshots - that's what it looks like while connected to USB no matter what cable or PC it is connected to.
I'm actually trying to Frankenstein the phone, but can't even get past the part where the phone and computer need to communicate via USB because of the problem I'm having.
So I guess, has anybody ever had this problem and found out how to fix it? It's all I need so I can Frankenstein the phone.

I am finding this very strange too.
I don't have anymore computers to try.
Is it possible that it's still somehow tied to Verizon? It was recently used by a friend who gave it to me when he upgraded to a new phone. My calls / data work (I have to manually provision that) so it seems very odd that it won't full allow services / USB connections or even show the OEM Unlock option in the Developer Options.

I was editing my reply as you were replying. You had buried the important parts see the bottom, what all you tried.
No one else has any problems, to my knowledge. Tons of VS996 on this forum, who have Frankenstein'ed to US998 either permanently or temporarily to Bootloader Unlock and root.
All I can suggest is to try yet other PCs?
Other VS996 users can chime in, but I don't remember any reports of USB issues over the past couple of years.

I noticed that too, haha.
So isn't it supposed to let you switch USB mode even if not plugged in? When mine is plugged in or not, it acts as if the only option is "Charge" - if you look at the screenshots I attached, I've pull my top menu down where it should have a way to switch it from Charging to something else, but even that shows nothing... just charging, settings etc
I tried calling Verizon customer service just to see if they have some kind of security measure they sent over the air when my friend deactivated it from his account - but they're close, probably because of this COVID 19 thing (or they don't work on Sundays)...
@schwinn8, @nnjimmy59, @gimpy1
you all don't have any USB connection problems on your VS996, do you?
That's just three off the top of my head. We also had a Dev, TotallyAnxious who had VS996 for awhile and a very popular Anxious V30 mod -- but moved on to a newer phone a few months ago.
Never any mention of USB issues.

Well, my phones were not originally VS996. My personal phones were US998 purchases. The next two I purchased were H931. All of these converted via Frankenstein just fine. (One H931 had some issues, unrelated to the process - I believe it was a hardware problem with Verizon towers). That phone is now US998 running on ATT with no issues.
My wife and I are still running VS996 with no issues. I don't use USB much but I know it worked just fine last time I used it. I'm happy to test further if needed, but it sounds like this may be more of an issue with an originally-VS996 phone, as the OP is suggesting.
EDIT: To be clear, I don't think this is a real problem with the phone... probably just another "incompatible" computer/cable/USBport thing. So many people have these types of issues, and there's no guaranteed answer on what does/doesn't work. I'm happy to help if I can, though... I still have my older laptop which did all these steps just fine. I will say my new laptop (Ryzen) does NOT work on this process. I still have that older machine, in case it's needed again. If you love in the CT area, I'm happy to help first-hand...

OK. I'm pretty sure the others had original VS996, especially TotallyAnxious. I'm not going to officially mention her as she has moved on, but we communicated a lot when her Magisk mod was posted here.

I'm thinking it's probably because it's an original VS996 and Verizon is notorious for locking down their phones, even though they are carrier unlocked.
It wouldn't be a problem if I could just force the USB to work and get rid of all the Verizon programming...I'm really hoping someone out there has had to deal with this before and see this.

I'll go back and re-read your posts again. (edited below after re-reading)
It's probably also worth mentioning that it won't enter Download Mode following the instructions found here : https://droidrecovery.com/lg-v30-recovery-mode/ (scroll down to "Boot LG V30 into Download Mode")
-edit- As far as incompatible cable/computer theory - I don't know...it's the cable that came with the phone when it was new. My other cable was from a Samsung Galaxy and both work with my Moto X4 (which is what I'm switching to the V30 from). All drivers are installed, no driver errors in Device Manager, etc...This is by far the most difficult phone I've tried to work with.

The button dance is notoriously difficult to get right. Try it a few times. Note, in the steps listed, it says to release then press the power button again... but it's not clear that you need to HOLD it, not just press it. At least, that's what I remember it to be. I only had to do it once... adb is so much easier.
I also want to point out that one of my original LG cables did not work either. Not sure why, but it didn't. The other one did... as did a third party cable. Again, the key for me was my older laptop. The new one does not work, no matter what I try. Granted, when I say it doesn't work, I mean it wouldn't do the unlock... the USB does detect fine and the phone does switch into the necessary USB mode.
Can you change the USB mode manually somewhere? Maybe it was set to "charging only" by mistake at some point? I think the popup asks and has a "remember" button... if that was selected, it may be continuing to use charge-only by default?
EDIT: Found it... in settings/system/developer options there is "select USB Configuration"... set that to PTP and see if that works to get you in.

I attached a screenshot in an earlier reply that shows what that looks like for me - I tap it and it does (literally) nothing. No menu, no option to switch - nothing at all - and that is actually the reason I posted here to begin with. I've never had this happen. It continues after multiple factory resets as well, and on the same computer I've successfully flashed other phones with.
This may be relevant? Maybe it's a Pie problem?

Different phone, but same symptoms.
Hi. Not sure if I can help any. But, here goes. I am on a Verizon vs996. Been a Verizon customer for years, still am. I have four phones on my plan, but I am the only rooted one. I rooted my phone about a year and a half or two years ago via Chazz 's Frankenstein method first, then the WTF method second. I currently use, for some time now, US998 rom (pie).
I did experience a couple of problems, but, carefully using/following all the instructions listed, got it done. My computer (at the time a surface pro 3 with windows 10) would not work for me. I finally borrowed an older laptop with windows 7, I think. That worked like a charm. No problems with it.
Other problems I personally had was understanding what the instructions actually meant for me to do, as I am not computer literate. I remember I had a hard time figuring out how to put the downloaded files into a folder in the correct location so the computer could find it. It really wasn't hard, I just didn't know exactly what they wanted or meant to do it.
Another problem was understanding how to use the "command" prompt. I had to click on something other than the command prompt (it was either a newer or older name for it - can't remember which). But, once I got it figured out, everything went smoothly and flawlessly. Somebody (ChazzMatt(?)) had linked to a different suggestion - can't remember what it was - but that worked.
What I would do now and what I did was, go in and print out the instructions. Once they are printed out, go thru it line by line, word for word and cross out everything that does Not apply to your phone, situation, etc. Read the remaining instructions over slowly and make sure what you are reading (and thinking) is exactly what the instructions say.
Messing with your phone can be very nerve wracking. It was/is for me, every time I do it. That's why I would print out the instructions and follow them exactly.
Sorry that's all I can add. I have to have exact explicit instructions and follow them (dummy mode).
As far as the button dance, I have never had a problem getting into twrp using it when changing roms. Magisk seemed to never install the first time and I could only get into twrp by using the button dance.
The reply to that reddit thread says that another user has it working in Pie. I wonder if you just have some weird corruption on your phone. I think you said you did a factory reset, correct? What I might suggest next is to try the Verizon repair process (they have some software that can supposedly reload the OS or something, as I recall). Maybe that will get you to a running state again.
And, again, try the button dance again a few times... I know it's annoying but it may work. If that gets you into download mode, you can then drop a KDZ for Oreo (or just jump into the Frankenstein method)... and you should be good? It's certainly weird that you can't get in there...
EDIT: Looks like not being able to access this setting does seem to affect a few phones on Pie... a quick google search confirmed this: https://www.google.com/search?client=firefox-b-1-d&q=android+cannot+change+usb+mode
Another thing to try - open up device manager, then plug in the phone and see if the list refreshes. This will tell you that Windows is "seeing" the phone, and maybe you can find out what driver it's trying to use. Maybe that's the problem? If it doesn't refresh at all, I would still suspect the cable...

All I need is download mode and I'm ready to get this thing going, haha.
One of my computers detects the phone (it thinks the USB port can't supply enough power when I plug the phone in) but not as the device it is. The Windows 7 machine - nothing.
-edit- I tried that app just now and all it does is detect Android version and then if it's 6.0 or above, sends me over to Developer options. Seems like it just skips the part of going to it via the Settings menu... (indicates this phone is not supported by the app, based on the app's notices.
-edit2- Can someone link me to a video or screenshot walkthrough for the button dance? I may just be doing it wrong based on reading it, and the only videos I can find are for old Moto phones. Is that the same 4 corner thing?
edit3- I'm looking for anything Verizon may have to rebuild the OS...if anyone has some insight as to exactly where I can find this, that would be great.
When I attempt to enter "download mode" (same method as mentioned in a previous post) as suggested by one of the Verizon program that can repair it, the phone just charges and never enters any special mode.
