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 all... i got my V for a month and now it is not charging anymore. neither from the ac adapter nor my computer usb..and my computer couldnt detect my phone is plug to the USB port....just nothing pops out. The debugging mode status icon, and the storage icon is not shown on my phone.
basically... i tried everything i found on Google...
reboot my phone, pop out the battery, change cable[from other optimus V], changed battery, different ports on my computer, different computer, different AC adapter, different SD card, format my SD card, factory reset, and the last thing i tried is to rooted my phone and flash with a I.H.O CM7.1 ROM.
no hope at all; however, when i plugged to the usb port or the ac adapter, then i take out the battery.. the phone does power up and say required battery....
so, if anyone had this problem before and solved it.. please help me out. between, i cant return the phone anymore.. it is over a month.
forgot to mention... it is the second time this charging issue happened. the first time, it fixed itself after i plugged into the PC, windows recognized it, and installed the drivers. [well, i already installed the driver before this happened, because i was doing some coding and debugging]
this time.... windows is doing nothing, no message pop out, no new driver found.. just nothing. and my phone doesn't shows the debugging icon on the status bar even thought i ticked the debugged mode On, and connected to the usb.
sorry for my bad grammar =[
maybe see if your pc recognizes it while rebooted into recovery.
you could also try removing all the lg and Android drivers in device manager (select show hidden devices to get at them) and then plugging the phone into the pc again.
or use a Ubuntu "live cd" to check the connectability... micro$oftware is uppity, my kid's windoze computer doesn't like my v, although it used to see it fine.
I've also read that toggling debugging, disconnecting and reconnecting the cable, then toggling usb debugging again can help.
also, froyo roms are supposed to go to a charge mode when turned off but still plugged in.
Hi guys, i realy need your help, my phone is dead.
My I9100 worked fine for two years, I flashed lots of custom firmwares by Odin. Half a moth ago, when I was going to sleep, I plugged in the charger as usually, and noticed, that it started beeping occasionally. On the display it indicated smth like: Charging... than Not Charging... than Charging and so on.
I thought that I plugged the charger incorrectly and replugged it, but it didn't helped. I was very tired and just simply turned the soud off and left the phone charging. In the morning it indicated that it is charging even when the charger was unplugged.
So I've flashed the firmware - no help, than kernel from stock to fillz - no help , than siyah than again to stock - no help. All flashings were maid via CWM. I realized that flashing will not help when I turned off the phone and it was indicating that it is charging.
I decided not to do anythig. Only USB mode didn't worked because when you want to use your phone as USB you should open the apropriate mode on the phone than there will be smth like : plug the USB data cable to enter the USB data transfer mode. I couldn't do this because my phone thought that the cable is already plugged. In forums i've got hints that my micro usb should be cleaned or small board should be replaced. So i decided to clean it. I disassembled the phone and cleaned that board with micro USB. Than turned on the phone, and connected the cable. Phone recognized it and I managed to transfer files from pc to phone. From this point I can say that all terminals on micro USB are ok.
When i unplugged the cable, phone thought that it is plugged((
The most awful part:
I decided to flash it one more time and go to stock via backup made by CWM a year ago.
But during this process the phone made a reboot by itself and after that there was no loading. I can see only name of the device and thats it.
No recovery. Only download mode.
When i connect it to PC in download mode, there is a sound that USB is connected but the device is Unknown. There is no any information about this device in dev manager on PC. I tried two USB cables, all usb ports, two laptops, all versions of USB drivers for my phone.
Earlier, drivers worked well, but now i can't understand where is the problem: Is the problem still connected with my micro usb port or i just erased boot sector and it is already brick.
I gave my phone to service center, they told that they can't help me with this. They say that usb is ok, we don't know why it is not detecting by pc.
Can the board replacement help in this issue or maybe i can do smth. in linux with my device ??? I'll appreciate any suggestions.
Yesterday I talked to representatives of service center and they told me that the problem is that internal memory is damaged and they cant flash the phone.
I took the phone and tried to flash it via Heimdall with brick fix pit.
After using this pit file, the phone was flashed normally and even turned on normally.
But in the phone info menu I saw no any data about internal memory. (It was damaged and required format). I tried format through phone menu and it did nothing.
I decided to flash the phone via Odin with normal 16 GB pit file and had a bad luck. I experienced freez during repartition. After this, phone is a complete brick.
When I connect it to PC without battery pressing vol down and rower buttons it connects as unknown device but there is nothing on the phone display. No recavery no download mode. Nothing - just reflection of my frustrated face).
Currently i'm tring to make a Jtag, maybe it'll put it in the download mode, but hope is dying....
I've herad somewhere that it is possible to put it in the download mode in linux. If somone did this, could you please give me the contact of this person?
Hello, I have issues connecting my S3 international model (i9300) to any PC. It has CM11 since at least 6+ months and it worked just fine and connected to my PC two days ago just fine.
Some days ago, it started bootlooping because of the common power button stuck problem [turned on by itself when battery inserted, and rebooted in the Samsung logo, which doesn't even let you go to DOWNLOAD mode or Recovery because it just reboots after a few seconds]
Yesterday I disassembled it following fixit guides and youtube step by step guides to make sure I didn't break anything. I saw the button problem was internal (the button apparently works fine, but internally it has a closed circuit so it seems as pressed). I assembled my phone again and went to bed. Today it was working without bootloop. I saw this as an opportunity to make all the required backups just in case it went to bootloop again but I couldn't get anything from it. Windows doesn't recognize it at all, not even during boot. Here is what I tried:
*Tried in several PCs/Notebooks/OS with different cables that work with other phones
*In all cases it charges the battery, but the PC doesn't see it as a device.
*I rebooted the phone by software (so I don't press the power button at risk of getting bootloop again) going to terminal emulator and using 'reboot' command.
*Rebooting the phone connected to the PCs doesn't either cause any device to be detected by the PC during the booting of the phone.
*Thinking it might be the port of my phone, I tried an OTG adaptor and several pendrives. They all were detected by the phone and I was able to write and read the USB drives.

At first I suspected I left a ribbon/flex cable not connected to the board, but being able to use OTG USB drives and being able to charge it didn't convince me it was the case. I want to avoid disassembling it without knowing first which ribbon to look at and any other test/information you could tell me to provide in order to find the solution.
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,
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
