I just replaced the ROM on a Qtek 2020i. It took me a day and a half to get it done. I tried everything I could think of to make it work. It got stuck in Bootloader mode and nothing I tried would work.
I finally use a different USB port on my computer and BANG, everything worked fine.
Does anyone have an explaination why using a different USB port made a differance? I'm at a loss to understand why.
Hope this helps others that are in the same situation I was in.
at times windows try to install drivers and it goes wrong
drivers for usb devices are tied to the usb port they are connected
to and moving the device to another port reinstall the driver
hello,
mi micro USB is not working propperly right now, for some reason it doesn´t charges correctly, it seems a little... "loose"... im currentl running CM 9 2012/05/26
and when it plugg it in the computer and manage it to start charging, it wont allow me to acces it as a mass storage device, in fact the computer wouldn´t recognize it at all!, any help!?
try another cable, or connecting it to other port after rebooting (usb musnt be connected)
Swyped off my Amazing Defy using ICS
happened with me too, got its motherboard replaced
crap... I`m rooted... so no warranty...
maybe in some repair shop of cellphones the will be able to replace it?
but.. did yours charged at all?
bacause mine does charges when appropietly connected... its just that sometimes it wont nad it will not allow me to get to the mass storage...
If your phone just charge but can't access to masive storage, look in the device manager , if you have a MTP device, your micro ubs port is fine, just try to install some stock rom.
it´s just that some times it doesn´t charges and I need to slowly start trying to adjust the micro USB port so it can charge... that´s why I say that it seems to be a little loose...
As well it will only charge when plugged into my XboX 360 or the computer (and some other devices) but not when plugged into the Stock charger... :S

USB not working for flash
Hi everyone, I came with a similar issue.
The massive storage USB connection is not working for me, plus I can't flash a stock rom,
Currently I'm in MIUI for defy (and it's the only option I am able to install), I tried to wipe data cache to install cyanogenmod 7 from recovery but it's not working, it get stuck in the boot logo. I want to install cyanogenmod because it is fast than MIUI jelly bean.
My idea is to flash the device, but with the usb not working Im stuck,
any ideas to solve this? or should i go to have the usb repaired?

If after a boot in bootloader (power+vol-up) and connecting to PC via usb cable nothing appear onto PC display 3 possibilities exist.
1. Usb cable is broken.
2. Pc have no usb driver foryour device (but even in this case a error message appear)
3. Usb connector or circuitry fron Defy is broken.

Yes, is OK your method but is a little dangerous if you not cover the cleaned pins with some resin. More safe is to use a toothbrush soaked in isopropyl alcohol or 98% ethylalcohol to clean the soldered pins.

Hey guys,
Just recently, my PC and any other PC Ive tried for that matter will not recognize my Note 3. I had Windows 7 and it worked fine for months, then just the other day it came up on the bottom as USB Device Not Recognized, and no matter what I do it will not do so. Yesterday, I upgraded to Windows 8.1 and still the same result. I have installed Kies 3, uninstalled and resintalled Samsung drivers and still nothing. I am running a custom rom in the stock slot using Safestrap...is it possible that that might have messed up something? Even when the cord is plugged into the PC, the phone doesnt come up with anything notification that it's plugged in, but it does say it is charging. If any of you have any tips or something please help because I am at my wits end.
Thanks
Have you tried with another cord?
Computer doesn't see device... Device doesn't detect plug in... Sounds like a bad USB cord

Yes, actually I have and still nothing...forgot to mention that in the original post.
It's a strange problem which leads me to believe that something has gone wrong in the phone, or that I caused something to go wrong by flashing a rom or three, since it did work previously. Unfortunately, I'm at status: Custom, although my Knox is 0x0.

Yes, this shows as disabled. What should this be?
Can't help you solve your problem, but last night I had a hiccup where I plugged my (17 day old) N3 into my computer in a USB2 port and ... nothing at all. (As if it were electrically disconnected - no "unknown devices" showing)
Tried it in a different USB2 port, and ... nothing.
Tried in in a USB 3.0 port - same computer, same OEM cord - and everything was fine. As far as I knew, nothing had changed on either end of things, although the previous evening I had used a different OTG cable for a USB key with the phone, and I had also had a automatic update of the Samsung Push Service on the phone. Nothing had been plugged into the PC's usb ports since it's prior cold boot. (Win 7 x64 Pro).
This morning (both PC and phone have been rebooted), everything is back to normal - both on the phone and the PC. Both the USB2 and USB3 ports all seem fine.
Ugh. Makes me nervous - brand new hardware.
Boot into Odin mode THEN plug the device in, let windows find the drivers for it then once that's done, reboot the phone regularly and see if it works then. It appears to be an issue with most to ALL Samsung devices, but this worked for my wife's galaxy S3 when the computer wouldn't recognize it and the phone didn't detect a PC connection.

Did you fix this problem?
Thank you! Worked perfectly!
I have the same problem, do you have any solutions ? Thanks.
I too have been struggling with this problem. The is no USB symbol in the notifications area on my phone whether I plug into to my computer at work (Win7) or at home (Win7), using a usb3 cable or a usb2 cable. Its as if there was a setting on my phone that allows recognition when plugged into a computer that has been turned off.Is there such a setting? I would love some help on this as well. Thanks in advance! I am rooted with towel root and have had no problems until last week. When I look in the device manager on my computer it shows :
SAMSUNG Android Phone
SAMSUNG Android ADB interface
I tried uninstalling the above and then plugging my phone back in and it re-installs the same driver shown above.
For what it is worth here are the drivers for SAMSUNG Android ADB Interface:
c:\windows\system32\DRIVERS\winusbsys
c:\windows\system32\WdfCoinstaller01007.dll
c:\windows\system32\WinUSBCoinstaller.dll
Should I be using different drivers ? Thanks|!
please help!
any solution yet? i have same problem, no usb detection and camera wont work i want to flash stock rom whit odin but i cant get the computer to recognize my phone...
I was able to fix the usb recognition problem. i had to do a factory restore. I lost root but gained usb recognition AND the Over the Air update to 4.4.4 and patiently awaiting the update to 5.0 hopefully this month!
Hello XDA, my virtual phone heros, i appreciate your good work, i am reading here for a few years as a ghost and today i signed up because i am lost with a serious problem on my Note4 N910C (English is not my native language)
THE CONDITIONS AND ENVIRONMENT:
My Phone was first running on stock Lollipop 5.1.1 when i rooted it over ODIN 3.10.6 with space X kernel and CF Autoroot, SuperSU then i flashed the latest TWRP...
After that i flashed a Custom Rom: Sweet_ROM_V17.1_COJ2_N910C...
Everything was running flawlessly for about 2 weeks...I installed Titanium Backup, Xposed, Xprivacy Pro, Busybox and a lot more and made a complete TWRP Backup then, it was running like a charme...The backup is fine because when i messed up my phone through trying harder xprivacy parameters and other tweaking i needed to set it back by TWRP into the old state...
Nothing happened after that, it was running 100% for over a week of heavy usage...
THE PROBLEM:
The one morning i took it from the charger with 100% Battery and went to work...
Before the error occured I did some searching on the internet, used chats. movies, nothing special this day, USB Debugging was On, i remembered something messed up my chrome browser like this ad hijackers, i set it back by erasing data,cache of chrome in the app menu, then there was nothing else strange i remembered, my AF Firewall was closed, only Whatsapp and Browser were allowed to going through...
The same day in the afternoon i tried to use my car charger to recharge my Note 4 as usual, but this time it wasnt recognizing the charger and my first thought was that the charger is faulty or the cable, so i turned off the phone by the androids power menu...I retried loading my battery In the phones off state but when i plug in the charger, the battery symbol came up for short and then it remained dead, it s the same scenario until today, so i used my powerbank to try charging, because the powerbank has an indicator to show the loading state and everytime i plugged it in, it came up for short, battery symbol shows up for a few seconds, but no percentage or animation is showing as usual and no red LED, then its switching off, the powerbank LED indicator stops the loading state after a few seconds, so the loading current stops...
At home i tried the stock charger and it remained the same, since that, i have to charge the battery outside the phone...
The strange thing is:
The Rom is still booting fine, TWRP is booting, but its not going into download mode from Androids Power Menu like before, its always just rebooting back into android if i choose download mode and i have to take the battery out and back in and hit the download mode pattern Vol- Home Power, to enter Download Mode and even the booting into Download mode from TWRP gives the same strange results:
On my Laptop i started the device manager to see the USB hardware string parameters after a windows popup was telling me something like "Device not recognized"
The USB Driver ID dont fit the old right driver ID, it seems to be empty and the port is not communicating anymore
since the charging bug occured,( Everything worked fine the day before.)
I tried my Laptop to narrow down the bug with the same driver i used for flashing phones (S6,910F,910C) over ODIN and my Lappy has USB 2.0 and USB 3.0 ports.
I always used the same USB 2.0 port for ODIN and other MTP stuff, but since the bug showed up the 910C is not recognized at the USB 2.0 Port anymore, seems to be dead in the devices manager table, only the USB 3.0 Port shows it as unknown device with a strange empty ID --> I tried the other devices like the N910F and G920F that are still recognized by ODIN on the same USB2.0 and 3.0 Ports both with the same USB hardware strings, its just the N910C that isnt recognized anymore, in no mode, no ADB, MTP, no download mode, everywhere the same, USB is bricked! Windows finds no driver and says its no info avaiable on this device so I tried to force the right driver to run with the wrong buggy driver ID but its not communicating, ODIN indicator and log remains unchanged...So it seems to be the same situation like other people getting from killing the bootloader by bad flashing, the only difference is that my phone is still booting fine into recovery and even Android but with no charging. My USB Port is totally useless now, its like if Samsung or Google OTA update has overwritten my bootloader or something hidden in the rom that woke up to kill my mods i dont know and now.
PS: Things i tried so far with no results on fixing my issue....
1. Complete fresh reinstall of Sweetrom, 2. Flashing another kernel...
3. Roll back to my TWRP Backup of perfect running ROM but with no USB support anymore:
The Phone remains in unknown state, not affecting ODIN to switch into flash mode
I am sure its the bootloader, since its battery bug is still occuring while the phone is in off state...
Unable to tell the charger the right ID without USB communication...
i was wondering if there is a solution to make a bootloader hotflash from out of Android or something like getting me back on stock first with download mode, forcing the USB ID or communication with a tool out of android, SD card boot image like on note 3 whatever, please tell me! I cant find something related to my USB and Charging ISSUE
PLEASE HELP ME, I am lost
Still the same. It's booting fine, USB2.0 no reaction on the laptop in Fastboot/Adb/Mtp ... On USB 3.0 Device remains unknown with strange Device ID String in windows 10 hardware Manager... Forced the old formerly working driver, but Odin can't find it anymore... Adb, Mtp, fastboot don't work, no communication... USB Cid is hard bricked, Charging never works in no state, just showing up for a few seconds in off state while plugging it in for short.... Bootloader must be damaged, fastboot and twrp can be started with dead USB... So is there a way to run a boot image to fix my bootloader from SD card, Aroma, or like OTA Updates are flashing? If Samsung and Google apply bootloader updates over OTA and simply restart, why we can't do that??? I need a new bootloader, is there any way without USB?
Greetings,
Thank you for using XDA Assist.
I have moved your question to your device's Q&A forum. You'll receive expert advice here. Good luck!
Fixed!
The problem is the USB Connector Port itself, figured it out after bending the inner contacts up with a flat screwdriver and cleaned them. Before that i always tried the same gently with no change, but please do it at your own risk only. After searching for many hours about possible reasons for the problem, I came to the conclusion to even compromise the Port and heavy bending it up, now it's charging! I will exchange the port soon and change the frame too to have it back like as new... OK, if anyone in the future have problems with the bootloader or USB hardbrick n910c, feel free to ask me, I upgraded my knowledge on many causes now
Thank you very much
My 2cents stick to one charger. Do not share that charger with others.
The worst culprit are the cheap china car chargers.
I went thru two USB ports on my first phone to figure this out.
Ever since I have adopted the policy of using only one cable. Never had this issue.
Hi, I really need help. three months ago, some weeks after my Mi 9T overheated on sun (don't know if that has some relation to the issue), it suddenly stopped charging while on, unless I rebooted or turned off. Also, it had difficulties to transfer files to PC and connect to a flash drive by OTG.
Then, I took it to a guy and he said I needed to replace the charging port, and so I did. But only now, after a serious issue. I was changing my rom from MiRoom (MIUI 12) to Evolution X, since the MiRoom's developer ended the rom's support. But It didn't work, It boots into Fastboot mode. I tried to connect to PC and OTG, on recovery mode, but neither worked. The PC doesn't recognize my phone, and the OTG flash drive isn't recognized by the phone.
I bought the charging connector online and paid that guy to replace it. The port feels better, the connector feels way steadier when pluged in, but I still can't know if it charges while on and file transfer to PC or OTG is still not working. So, I'm stuck on recovery mode, in a rom that doesn't boot and a USB port that doesn't work properly. If anyone has a clue of what part I might take to replace or a repair, or maybe a software solution, if that's the case, I would be really thankful.
