After unlocking bootloader(or maybe after flashing several roms.. i dont know exactly when this symptom began..), My Mi 5 can't recognize any USB connection.
It's weird because in fastboot mode all things are working properly. And restarting also makes phone recognize usb connection.
This makes me crazy. i have to restart or enter fastboot mode to recharge a phone or transfer files.
Is it a software problem or a hardware problem. I need a help..
i have similar problem. my phone not charging or connecting usb until i reboot it. it's weird.
did factory reset and other things but nothing worked.

Hi all,
I have a huge problem. I dont have USB mode anymore. When I plug the phone to my PC, it doesnt ask me if I want to connect it as a storage mass. It is only charging; windows doesnt recognize a new device too, so I cant use nvflash.
Besides, I dont have the recovery mode, I cant use it to install an previous rom...
Can you help me please ?
I have the same problem on my G2x after flashing ClockWorkMod...
I had the same problem. I asked the retailer for an exchange. However, just before I returned it, the phone was plugged in to my laptop USB for charging and all of a sudden there was a notification saying that USB was connected. I had done a factory reset before this but it hadn't helped.
You could try enabling Hidden Menus and then in Port Settings try changing from AP USB to CP USB and see if it helps.
Also, try reinstalling the drivers on your computer.

Make sure the cable is properly connected. Check for dust that might prevent it going in properly. Try a different cable. What OS are you using? I found where bootloader is dmg or incomplete Windows fails to detect it. Linux on the other hand detects it. Can't use it but you can detect it.
Can you connect to SW Update Mode? Battery out and plug into PC while holding vol up button.
If nothing works try taking it into the shop.

You can root your phone from there. If you have SW Update. I recommend taking it into the shop if you are still under warranty, If you don't have warranty then you can go ahead and root. Just install a patched bin and fls with Smart Flash Tool. It's one of the stickies (How to unbrick, I think)
hi
new to Android nation
I have the same issue when connecting to USB...
And I managed to flash with custom firmware (latest ZEUS version) and I rooted but the issue with USB connection is still there...
Anyway, I wiil try connecting it to Linux to check if that would work with USB connecting
UPDATE:
OK after some digging, I managed to (at least temporally) solve the issue... After fresh installing official 2.3.4 firmware I booted to recovery and from there formatted the system folder and then installed Zeus v7 firmware... anyway, USB connection and charging indicator work fine at first booting to system... As soon as I reboot the OS USB connection (and charging) get unstable, and after third reboot it completely goes away and the device does not recognize anything: if I connect USB cable it does not show any sing (charging indicator does not show battery charging, nor the device offers me to connect in mass storage, windows recognizes only modem but not the USB storage) and when I connect charger, battery indicator does not flash as charging... Battery monitor tool shows that "battery is discharging" even though the battery capacity seems to increase (according to growing percentage of battery capacity)... Is there a some kind of USB server... I am a total noob to Androiid OS (used to be Symibian from its beggining )so I hope you won`t mind if I used wrong terms in my explanation/comment...
I hope my explanation is not confusing
Cheers
UPDATE 2:
After installing Zeus v7.01 update, battery charging recognition got fixed using both USB cable and wall charger...
Anyway, USB recognition by PC problem still exists... But when in recovery mode I can successfully mount SD card to PC in Mass storage mode...
Will keep you updated... :victory:

Probably a hardware problem then....
I have had the same problem for a few weeks now. It started to fail occasionally and right now the usb won't work unless you reboot the phone. If i'm running out of battery, i must connect the charger and reboot for the phone to charge. And when the phone is charged, if I unplug the charger, the phone thinks it's still connected.... that is until you reboot again. It's a pain in the ass because also the phone wont go to deep sleep (ab8500 charger attached wakelock is keeping it awake at all times).
I was waiting for mi carrier (Movistar, Argentina) to update to Jelly Bean so i wouldn't need to downgrade (as i read some people experience CSC problems when downgrading) but I'm starting to grow impatient...
Same problem dude..
Hello all, I have a strange problem on my xiaomi 8 phone.
Every thing works fine, the phone is BL unlocked, with global rom installed and can be OTA-updated.
Now I want to re-lock the Bl (because of google pay), so I booted to fastboot and the strange thing happens. When I connect to the usb port of my win10 pc, nothing happens, the device manager also show no new device or unknown device. And I als connected to my ubuntu server, dmesg show nothing, and lsusb also show nothing new.
So the issue is, in fastboot mode, my phone seems not be responsed the usb connection. This is boring, because I also accidently replaced the twrp with stock recovery, now I can do nothing on my phone without the fastboot connection.
Any one has an idea or simillar issue and have a solution for it? Thanks in advance.

It sounds like you accidentally relocked the bootloader.
If so you will need to repair the phone in EDL mode by using QPST. There are plenty of how to guides available. You can buy a EDL cable from Amazon

I have a very weird issue with my S10: it wont connect via usb to pc. Once connected a notification should display and the option "file transfer" should be there, but no such menu appears. When i plug it in to a pc it just starts charging, the pc also does not see a (bad) usb connection or whatever. I have been reading fora and watching youtube for over 1,5 hours. I feel now is the time to ask for help.
What might be usefull context: i have had the "moisture detected" error many times, it started showing up 2 weeks after i bought the device. Gladly i mainly use wireless charging so effectively it hasnt bothered me much, but it was weird since even after waiting for hours for the phone to dry (i dont think it was wet but whatever) the error was still there. One week ago the problem got quite severe, lasted for more than 24 hours and it just refused to charge, tried rebooting, turning it off, going into safe mode... to no avail. I had no wireless charger then, it was nasty.
I am using the usb cable provided by samsung (but used two others as well).
What i tried:
wiping cache and data from usb settings
wiping cache via recovery
reinstalling samsung drivers to pc
looking for a yellow exclamation mark in device manager on pc (not there)
different usb cables
different pc's
different ports on pc
rebooting the phone
booting in safe mode
installed dex on pc
via developper mode select file transfer as standard
via developper mode select any of the other modes to see if that helps
via developper mode revoked usb debugging authorizations
via developper mode enable usb debugging
The next logical step seems a factory reset. I am unwilling to do that however, since there are many gigs of photo's on the device that i want to backup first (the whole point of trying to connect it via usb heheh).
Your advice please!
Your could try to reflash your present OS via Odin but when doing so remember to use HOME_CSC. This way your data will be present when done flashing and phone reboots.

How he can do the flash with odin when phone is not recognized by the computer !
Clean the charging port with a clean toothbrush and try again ... Also make sure that the charging cable supports data transfer ... If you tried all of these things and did not work, then most likely the charging port has a problem that may be oxidized or cut in the tracks..Try the solution that I gave it to you, and if it doesn't work, take it to a technician
charge from the wall.
I too have a similar predicament. Tried all the cables and USB ports I could get my hands on... I have a custom ROM also, so it could be that. I have done a full format and reflashed ROM (from SD card) - but it made no difference, the phone refuses to communicate via USB.
SO, if you have any solutions, please let me know!
I can however communicate via ADB over network. So, if you know some adb commands you can pull over an entire folder with the "adb pull" command.
