Hello!
I've been having this problem out of the blue with my BQ Aquaris E5 phone: it does not respond to any USB connection (either to the PC or charger) if the phone is on. If I keep the cable connected and then restart, it will charge without problems. Once the cable is removed, it won't charge if I connect it again (until next reboot). If I restart the device without cable and then connect one, it won't work either. I did a factory reset, which did not do the trick; and even flashed the device with the latest ROM, also without effect.
Any idea of what could be the problem? I have not found anyone having the same problem, and solutions such as modifying the USB profile in the developers mode or clearing the cache partition has not done the trick.
I have this problem on a Leagoo Kiicaa MIX and tried the same things before I found this post. Did you figure it out?

Hi, I have the Chinese smartphone Uhappy UP920, android kitkat.
I tried to root my phone with kingoroot and all other root software before one week, without success, kingo always said "connection with servers failed, try again", I tried it two days from different libraries & I tried some software for upgrade, just to see if it is possible to upgrade to the android 5 & 6, the upgrade was refused because developer didn't make such possibility.
I don't remember from all this software if I used any software for flashing device, but here is the problem:
in one moment after trying all these software, I saw that phone battery dropped from 10% to 1% and the USB cable didn't work any more, I tried OTG cable also but the phone didn't recognize my USB device, when battery was gone/spent, I tried to use USB cable to charge the phone with my computer, but no success. I don't have ac adapter (charger), I think it would not work in any case because OTG cable is not working, not only USB cable.
battery is gone, I can't charge it with USB cable, I tried to make restart with "down volume button" and "home button", but it didn't work.
when I press Power On button, display become something like blue for a second and it is dark again. I can't start the phone.
my theory is that some software destroyed possibility for android kitkat to recognize smartphone microUSB port (for USB cable, you can see that port on the photo: https://img.fasttechcdn.com/231/2314500/2314500-9.jpg). So, maybe it is software problem, maybe hardware problem...
anyone had similar problem? anyone has a solution?
p.s. before battery was gone, USB debugging option was checked, that's requirement when I tried to root the phone, in theory I could try ADB to do something with the phone, but I don't know how to use ADB, I tried to list devices but I got everything black in the terminal, I didn't get listed my device. if you recommend ADB, please tell me what commands to use.
Hi guys, i'm Claudio. I'm new to this xda community and before i start i want to thank you in advice for your help and i want to sorry for my bad english ^^.
Two days ago my Redmi note 3 pro had a random reboot during charging and it stops booting up, with AC adapter it shows only a blinking red light. I tried everything and finally manage to boot into fastboot mode by removing the case and disconnect battery pins and reconnect them. Now every time my phone accidentaly or not reboots with the AC adapter attached, it dies and i need to open case again and disconnect battery pins.
P.S. I can charge my phone without any problems.
This i not the only problem i have now:
- OTG does not work anymore, system do not detects any kind of usb device, Pendrive, Mouse, Keyboards, Gamepads etc.
- In Settings USB options are not present anymore (MTP for exemple), tried any kind of programs and drivers.
- I cannot disable VoLTE.
- My PC shows "Device not recognized" when i connect my phone. It acts like my PC did not manage to read phone firmware and don't know what kind of device i connect.
Strage thing is that i manage to manually install Marshall Bootloader ADB drivers and now i can flash roms with fastboot method.
As you can see is not a problem caused by damaged data usb pins because i can flash ROM's, Recovery mods etc. It may be a problem caused by a damaged partition, maybe a locked one witch i cannot flash using Miflash tool but here guys i need your help because i don't have any experience with nandroid backups, partitions.
Actual configuration:
Miui Stable 7.3.7.0 (also tried miui 8 global developer, nothing changes)
Radon 2.3 kernel (even with stock kernel nothing changes)
Bootloader officially unlocked
I will give you any kind of information you want, and i will try everything. No problem if i lose my data. Thank you guys! :good:
Hi,
I have a Hisense u989 pro with a custom recovery installed, I performed a restore from a previous backup. After completed, when wanting to reboot, I saw a msg "No OS installed, leaving the phone connected to my pc and charging via usb, my wife needed a usb cable and unplugged my phone. when I returned some time later the phone was completely dead.
Some issues: Phone not charging or switching on, cant boot into recovery or fastboot, sp flash tool not detecting phone via usb cable, tried different usb cables, cleaned the micro usb charging port. left phone connected to charger for over 24hrs and still nothing. Im unsure whether it could be the charging port or the battery.
Ive got the hisense u989 pro stock rom, i just need it to switch on. Any advise or assistance to resolve my phone issue will be appreciated.\
thanking you
Hello,
I am presently facing a strange issue with my Honor 4c. Nothing has gone wrong on my phone for almost 1 year but recently, impossible to charge my battery while my phone was on. Today, after a few weeks thinking my phone was just dieing, I have tried to make a back up and wanted to save all my data on my computer. However, impossible to connect my phone to my computer. Then I realized the problem was probably due to my USB parameters (No interface asking for mode to choose when I plug USB).
I finally did my back up but issue is still there : I can only use USB while my phone is OFF... meaning I only charge my phone when it is OFF..
I did not find any solution on internet and did not find an option to allow this interface to come back, even by trying to go in "developer options"
Could you please help?
Thanks
Tahir

Hi,
maybe one of the experts can help...
I have a LEMAX2 with X820_20S_ROW_CUOCO92 ROM.
Since half a year or so the USB-Connection to the PC does not work anymore. Tried several cables and several PCs, no change.
I can boot the phone in RECOVRY Mode, but it It shuts itself off immediately.
I can enter fastboot mode, but the phone is still not recognized by the PC.
When I connect the phone via MyPhoneExplorerClient, WLAN works, but MyPhoneExplorerClient says 'USB-Cabel 'Not conneced.'
When I unplug and re-plug the USB-Cable, for a short time MyPhoneExplorerClient says 'USB-Cabel 'conneced', but no setting option for USB configuration can be found and after a second or so MyPhoneExplorerClient shows 'USB-Cabel Not conneced' again.
I tried to find out how to change or repair the firmware but all howtos require a USB Connection.
Mayby I accidentaly removed some system software responsible for the USB Connection?
Any idea?
