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

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?
I was having issues with the charging the phone (slow charge in AC) and connecting it to PC through original charger/data cable. So after changing the data cable (in warranty), it solved both of the problem. But now after 1-2 days, charging is okay but I can't connect the cell with PC at all. It just charges the phone but by showing the error 'device not recognized'. I tried multiple PC/laptop but in vain. Also when I connect my phone in to fastboot mode, it just flashes the device and gets disconnected. If I try to flash twrp via fastboot it shows me 'failed: too many links' error. I'm on latest OOS 3.1.2 rooted with Xposed.
So anybody can tell me what to do?
P.S. also tried changing ROMs but no help.
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?
Hey guys,
I tried to root my SM-G930F and I probably have used the wrong ROM.
When I turn it on I got the following message:
"An error has occurred while updating the device software. Use the emergency recovery function in the smart switch PC software.".
Problem:
Phone will turn on just if it is connected to the charger/PC. (Otherwise the screen will be always dead black).**
**If connected to PC it will power off in 30 seconds or less.
OBS:
1. Phone NEVER turn off while connected to the CHARGER.
2. If connected to the PC it will turn off after 30 seconds, no matter if I'm in the message screen or in download mode.
Already:
3. Tried several cables (Including stock cable).
4. Tried to charge the phone.
5. Tried to remove SD card and SIM card.
6. Tried other USB ports and a USB Hub with external power source.
Any help would be great!
Thanks for reading and have a great day.
Did you tried to flash fast in odin stock image ? Did you tried with other charger ?
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
