After months of no problems yesterday I plugged my phone in for its nightly charge and noticed that it did not trigger the usual USB mount prompt.
I assumed it was Windows, but I have a bunch of machines and operating systems so I checked and they all has the same result. I switched out cords and did a complete power reset (taking battery out) no change.. The Phone charges through the USB but the computers say "unrecognized usb device" and cannot mount the phone as a drive and the phone does not offer the option as it used to???
I don't recall getting any sort of update that might have related to this?
This is the original T-mobile version
This happens to me all the time. However a restart of my phone and computer solves the issue.

Neither of those things worked for me. There's gotta be something else to it.

Go over changes you made to your phone recently.
only flashing another ROM worked for me... try reflash ur ROM, and wipe stuff if it doesnt work

This all started when I manually installed 2.3.4. Everything else works fine. I'm not the only one with this problem.

How do you do that without USB connectivity?
It is very frustrating, maybe a hardware fail? I see just enough post relating to the issue that makes me know it is real but not sure how to resolve,, Do we have to go to Best Buy? or is there a direct Samsung route?
This too happens to me. Whenever I plug it into my laptop on the top USB slot, it doesn't recognize it. If I plug it in on the bottom USB slot, it does. Not sure why. This, however, is only the case if I'm using a different USB cable than the one that came with the phone itself. Once again, not sure why.
Perhaps you are using an alternative USB? Or plugging in on the top? Not sure how I can help you more than that, sorry. Hope you find a fix!

Using official OEM cable that came with the phone. And, again, USB worked fine until I manually installed 2.3.4.
Well It is off to Samsung for repair
After time on phone with them and a factory reset belief is that the usb connector is defective. BTW Best Buy just hands off to Samsung 1-800 #
So Back to a barely functional G-1 for a while, glad I could find it!

Recently started happening to me, needed to transfer some files off, had to resort to dropbox etc.. rebooted phone+computer ,still not working.
Came good a few days later using same equipment, same cable,
Mysteriously fixed itself ?
Last week when I plugged my USB cable into my phone, it acted normal. The screen where it asks me if I want to connect USB came up, and I said yes. Everything was normal. It was baller.
Today, that doesn't happen. The screen doesn't come up and all the USB cable does is charge my phone, much like the wall plug does.
I've tried to install USB drivers, but they always require me to find "Android" in Device Manager, and it's never in there. The USB cable is doing nothing but charging my phone.
I managed to add a few mp3s over wifi, just to make sure that was actually working.
The phone is not rooted, (I was actually just going to try to do that) and everything is stock aside from a few apps.
I would really like some insight on this, please.
Do I need to get the phone replaced? Am I doing something wrong?
OK, I new to this, but thought I'd comment. If USB debugging is turned on, my seems to do that.
Settings -> Applications -> Developement -> USB Debugging

I've done nothing to the phone. Only installed a few random apps.
sorry to hi-jack your thread!
mine does exactly the same, but all i've done is manually update to 2.3.4 and my usb hasn't worked since, like you i've tried installing the drivers and that's done nothing and its also in usb debugging.
i don't know what to do or how to get it to work again, all my searching on here and via Google don't bring up much

Put your phone into bootloader mode and try whether it detect or not?
And also, see if there is two line of words written
USB init start
USB init end ;-)

Try another usb cord, and especially if you're using the samsung cord.

Wow, you're right. My HTC cord worked. Thanks a lot.
I have had this happen on to me and have determined that a) the long cable that came with the NS4G is unreliable when used for USB connectivity with my PC. Shorter cables (even the shorter Samsung cable that came with my Epic) work consistently. I am guessing that this is a USB Bus power issue and some people will have better mileage than others using the stock cable, depending on their PC.
b) on a few occasions, it seems I've somehow borked the PC's USB controller and the PC wouldn't recongnize anything until I rebooted it.

I am getting the

when in bootloader and when doing the i press vol up and vol down (triangle with android in it" with downloading below).
I would like to flash my phone to factory using Samsung Simple downloader for NS4G.
Background, installed Ice Cream but didn't have radio.img so used an SU to downgrade back to 2.3, did that but no mobile network. Then the phone updated to 2.3.6 and now getting that error. Any help will be appreciated.
I searched a few times on this forum and on google.com no luck. tried to adding a recovery file manually and zip it as update.zip and install from bootloader no luck. (use file explorer and dropbox to get files on to phone).
Thanks

Was your phone rooted at any point before the issue? Not sure if they would fix it under warranty for me. I will call Samsung and see.
Thanks, I tried that but no luck. Still need to tried other cords. Also.
My phone developed this problem a couple days ago. I haven't done much to troubleshoot it...figured the port must be damaged.
(Not using the Samsung cable, btw)

It might be the port. I will have to get a samsung cable and try it, but i doubt it will help. Plus i can tell Samsung I tried everything. (I looked a ticket, but they said get a samsung cord, they don't trust the Palm Pre cord i am using).
I had to downgrade to the HTC Hero until i get the phone fixed.
Hey everyone,
I have a problem when I connect my U8800 to my PC, whenever I do and I expect my SD to show up, it tells me that the SD card couldn't be read and that it should be ejected. I think it might be due to a faulty Mini-USB cable since it always has trouble charging the device (I need to put the device on the USB cable to put some pressure on it, otherwise it won't charge.) Is this just the cable's fault or is something else happening? I tried using the cable on another device and it seems fine. Nothing happened with the U8800, everything is in good state. Note: When at the Pink Screen and having connected the device, it shows up just fine on any PC.
Thanks!

I'll order another cable, thanks.
I've starting having an issue with my Nexus 7 where it wont charge anymore when it's running, even with the supplied USB charger and cable. If I turn it off it charges fine.
It's got CW recovery and it's rooted, so I thought that it may have developed a software issue and I would just wipe it with the stock rom and recovery and see how it goes.
However I selected debug and plugged it into the PC and the PC doesn't see the device and the device itself doesn't even detect its connected and show the notification. I've also tried on a macbook with no joy.
Using rom manager and CWM I have wiped the device and installed a different ROM (CM 10.1) and still no luck. Also, if it helps, the OTG cable with stick mont works fine.
Any ideas and thanks in advance.
Try a new usb cable...
Sent from my Nexus 7 using xda premium
I have tried a few cables now, and it's still that same.
Try a completely different computer other than the 2 you have issues with. You can also try wiping your driver's out and reinstalling them. If all else fails, pup the back off and check the solder joints and the flex cable of the USB.
Sent from my SPH-D710 using xda premium
I've just tried it on a different machine running Ubuntu this time and still nothing.
I'm going to guess that because of the unlocked boot and CWM recovery the warranty wouldn't be covered? If that's the case, how hard is it to pop open the back?
Thanks
No warranty till it is completely stock and locked. It's not hard at all. There are many tutorials you can find.
Sent from my Nexus 7 using xda premium
Thanks graydiggy. I'll see what tutorials I can dig up...
One thing that's strange is that it does charge when off, so you would assume the power joints are ok, and the OTG cable works so you would assume the data joints are fine.
Opened it up, everything seems fine, nice and tight inside.

Well,
My Lepro 3 has a very very strange problem :
Everything started Monday : it was at 20% and he just switched off, and then did 0 sign of life for like 4 hours (it was charging, but no led, etc..). After those 4 hours, the red light started blinking but still. And after 1 hour, I was able to boot (he had 10%). I decided to reset the rom, however, there was no way to get the phone recognized by my computer. I then decided to go to sleep and to charge to 100% the phone. Of course, nothing changed. And i even realized something worst : it takes like 5-6 hours to get to 100%, and it was 1h30 before.
FURTHERMORE : my lepro 3 isnt recognized on any PC, and neither in fastboot mod.
PLUS :
- when switched off, he won't power ON if i plug him to usb/sector.
- when powered on, he will vibrate TWICE when plugged to usb/sector : charging for 1 sec, then not charging for one sec, and then charging (like if he was trying to fast-charge, fails, and then switched to low-speed-charging
- when switched off, i sometimes need to press power for 10sec+ to get him booting
- I tried different cables
- tried usb debugging on/off
I don't know what i can try.. the only way seems to reset it with adb-wireless by pushing him a new rom but well..
I think it is a problem with my USB-C port (lepro 3 side) and i guess it is not using fast charging anymore
However, my headphones (usb-c) still work
Thanks in advance...
PS : I forgot to mention that i am running with Cydras Google-like rom 0.20S
I would switch to see makes a difference I have used that ROM without issue

Well I don't really know how to change the rom with no USB access.. Dunno if adb wireless is safe
Moreover, since the phone doesn't power up when off and plugged.. I guess the rom has nothing linked with this.. But maybe i'm wrong ! Could it be the kernel ?

i plug it : nothing happen
i try to power it on : it vibrates one but doesnt boot
I need to unplug it and then to power it on
EDIT : I just managed to install twrp with flashify, but i would like to know if it will be useful to install a new rom or if it won't change anything....

Yeah I tried..
It sounds like your usb card is fried.
I had this exact issue 2 months ago, I was lucky that the vendor exchanged it for a brand new phone.
It was probably fried by your usb cable. See if you can exchange the phone under warranty. Ask the vendor that you purchased it from, to honor the warranty, since contacting Leeco is difficult. Worst case, you will need to replace the USB card, its about $10.
VYeah, i guess it's the USB card... But there are two problems :
- its pretty Hard to disassemble a lepro 3
- i think that the original pro3 USB card comes with the vibrer, the speaker, and the microphone, and i didnt find any USB card with all of this on aliexpress...
He is no longer under warranty (15months vs 12)
Edit : another strange effect is that on cydras's ROM, the phone actually charges when powered on (but slow). On AICP 7.1.2, it juste says "plugged, not charging" when powered on

You are either bricked or its your battery, if bricked and the computer doesn't recognise the phone it still might recognise the port

Hey tsongming i have read quite a lot of posts from you in the last few days before commenting, i already tried before hand everything you said to get my phone detected by my computer and it still dosent get detected:
- tried multiple computers
- multiple cables
- and just in case, different driver versions.
Tried it all except the EDL Amazon cable you recommended in another one of your posts.
I have read that if i can't get it detected then theres nothing i can do.. which would suck.
ATM i have google pixel, beforehand i had AICP which worked really horrible on battery issues and would sometimes crash it. I have been using stock cable for 2 years which as i've read it the past few days is a terrible a ideia, and stock charger but as you say and qualcomm, i also believe its ok.
At this time i believe the problem might be a burned USB Card or the Battery itself bugging out(?) but since it charges when turned off (e.g: charged for 8 hours in supercharge to 84% =S), im clueless.
Since you said that you had the same issue on one of your Leeco, anything else you can recommend for me to try?
P.S: its worth noticing, i can Fastboot, Recovery to TWRP and turn it on, if indeed bricked i would call it a soft brick i guess..

If you can boot to Fastboot and Recovery, Then its not bricked. Your software is probably corrupted from a power spike or short. Its possible that your issue is just the USB card, which you can find for under $10, on Alibaba, Ebay and even Amazon.
Note that when you remove the screen do not use a Hairdryer to heat up the glue, there is way too much glue! You will need to briefly use a heat gun , and the screen will slide off with ease, the display and battery connectors are the lego type.. There are demonstration videos on Youtube.
Since you are removing the screen, you might as well replace the battery while your at it ( It should not cost more than $12)
If you want to buy a Backup LCD they are about $18 to $25 . ( definitely, recommend since there is a good chance of breaking the LCD, that you currently have)
If you order the screen, remove your LCD screen first to make sure that you order the correct one. They come with either black or yellow Flex cables ( not sure why) But if you have yellow obviously order yellow.
Make sure that the USB card is all inclusive and includes the chips, you are better off to spend a few dollars more for the better quality board. Sometimes the cheap ones come with missing chips for quick charge and CDLA ( Read the reviews)
Good Luck.
If you don't feel comfortable doing this, you can find Leeco Repair with a Google Search, or you can use TaoBao to get a "guaranteed fix", for really cheap. ( Even if its the motherboard ) They replace components and resolder) I doubt its the motherboard, but it's possible. In my case, I fried the motherboard and the phone still came on , but would not boot to system, also the screen was very pixelated.
