Some weeks ago, my Xperia U stopped detecting my USB cable as a USB cable.
It all happened one day, when the battery became weak (<15%) and I plugged the USB cable. The XU started to blink the charging light non stop, with the warning popup having the same behaviour in the OS (appearing, disappearing, appearing, disappearing...). So I unplugged it, thinking that it should be a problem with my computer USB port and plugged it to electricity. Only some days later, when I plugged it again to the computer, I came to realize that the problem was in the XU because it wasn't detecting that a USB cable was connected but it was charging normally like it should and it still does until this day (it still changes plugged to electricity too, no problem there).
Things I've tried so far:
- Enable/disable debug mode does nothing;
- Tested with friends' USB cables without any success;
- When I tried to boot into flashmode, Windows tried to install some driver and stopped with no warning;
- On a Linux machine, I checked the connected by USB devices and there was an error concerning the device but I couldn't figure it out what was it.
So, it seems like the USB cable detection is dead and I want to send it to warranty to have them checking the problem, but I have my XU rooted and it's with a stock ROM but not the one it should be (it's with that French one when ICS firstly came out).
That said, my question here is if there's anyway I can unroot and install my provider stock ROM (the ROM file is not a problem) without using the USB cable, so I don't have any problem with the warranty. I've used WiFi ADB app with success since I can connect to my device and perform adb commands, but I don't know what I can do with it to help me solve my problem...
Thanks in advance for your answers.
you can via Wi-FI channel's built to give ROM memory? If so, tell and through Wi-Fi ADB flash tis ROM, unless of course will
Yes, I can send the stock ROM file with ADB WiFi to my XU, but I don't know if flashing with 'just' ADB works, because I've always used Flashtool for flashing... Could you explain with more details, please?
I've been occupied and in need of my XU, and so I still haven't send it to the warranty, but I wanted to do it this week... So, is there anyone that can help me?
I'd be really greatful if you could tell me how you got flash tool to detect the XU. After installing a custom rom my device won't stay in flashmode. I have ALL the drivers.

Man, that doesn't even make sense on this thread. Please, start a new thread or reply on one that fits your problem.
hallo guys, i really need your help on this:
my sgs3 stopped working after running the official update (4.3)
its starts off well with the initial logo but doesnt start up beyond that.
Now my main problem is that the usb hub is broken so i have no other
means to connect the phone to the pc and sort it out through kies
or ordin.
im able to dismantle the phone completely so my question would be
are there places in the phone that i can connect the usb wires (naked wires) after
opening up the phone so that i can bypass the hub issue and have it connected to the pc?
im aware there are four important wires in the usb plug
another thing, i've tried installing firmwares from the sd card but they all
got rejected by the phone for signature reasons.
kindly help, thank you
Factory reset in recovery first, without a usb connection you can't do much.

Hello Everyone
I am putting my problem in this general section with the hope to ask for help to more people compared to the Mate 8 section where not a lot of people go these days.
Since a while I am not able to connect my phone to a laptop. If I connect it to a laptop it just starts charging but nothing else. I have tried everything like:
Changing Cables (tried more than 5. I dont have the original anymore)
Changing Laptops
Changing the USB port of the phone itself
Updating Drivers
Installing Hisuite (current version 5.0.3.300)
Restore phone to factory settings
Complete formatting
Updating to the latest version (Current version Nxt-L29C185B582)
Changing the USB debugging/ Connection (MTP/PTP/etc)
And what not
The problem is, it doesnt get detected on the computer and cant connect to adb as well. All I want is to unlock bootloader and Install TWRP and Magisk. I have the unlock bootloader code but no way to unlock it since I cant connect.
Can anyone help me in fixing this stupid problem ? It is getting frustrating. If there is a hardware issue, what part needs to be replaced? Any help would be appreciated.

Go to the Settings of your phone---> About phone----> Build number tap this 7 to 8 times-----> Developers option is enabled----> back to settings ----> go to developers option ----> enable USB debugging.
When you connect to the phone to the laptop you will find an icon on top of the screen of your phone with a USB mark "like a trident", pull down the top menu and find the USB connection tab, (like changing the sim card if you intend to call through a specific card) e.g quoted, double tap the USB tab to obtain options ---> 3 options 1) MTP 2)PTP 3) USB charging only----> select the first option MTP (Media transfer protocol).
Now connect to the laptop you will find exclamation marks in the device manager of your laptop. Load the appropriate drivers on your computer and viola! this will establish connection with the device you are having. if you find difficulty in installing USB drivers, search the thread "Attempt to load USB drivers for Micromax E484 on win XP is a fiasco" in this forum. You will find the solution for USB drivers

Nope. Doesnt happen
When i connect with the laptop, my laptop doesnt even make that sound for the connection.
What is the model and OS version of the device and the model and OS version of the computer? According to your symptoms your phone appears to be in option 3) USB charging only. The phone will not be detected by your laptop or the like(Computer) in this mode. Merely remains in a charging state. Are you certain the option 1) is picked MTP? If the phone is not detected there appears to be some hardware failure, try another USB port to connect to the laptop. if all else fail a service technician will pinpoint the fault. It may perhaps be a data transmission failure of the devices port to the interior of the phone. This is merely an assumption.
best remedy would be a service technician.
Hope this helps

I have tried changing the usb charging only to all possible options but it still is the same. I tested in Linux and when I connect the phone nothing shows up in the logs. It's like it's not being connected . I have tried changing the usb port itself from the phone but it remained the same.. can the flex cable be a problem ? Mate series was never launched in India so I don't have any help from the service centre. I have to order the spare from eBay.com so there is no qualified technician who can help.. that's why I have to fix it myself somehow..
Thank you for your help

I quite doubt the cable will be the culprit as your device charges the battery while in an established connection with the laptop. As you state the phone USB port was replaced, it could be a some glitch before the USB port in the device where there is an interruption in the data transmission signal that cannot be detected by your laptop.
Could you boot your device, computer and connect the two and take a snapshot of your device (whilst connected to the laptop) and paste the same in the forum?
Perhaps visual cue could be better at dealing such mishaps.

Yes of course. It is connected to a computer now. You can see it getting charged but that's about it

Can it be something because of some wrong flash ? This problem has survived through 2 versions and 1 system upgrade through firmware finder .. and a complete format

Your USB trident icon is not indicated on the device, If you were to receive power from the laptop the trident would be displayed on top of the screen, even for charging the battery. The power source for your device appears to from other than the laptop.
I have pasted my device after connecting to the computer and the second icon from the top left is the USB Trident icon indicating connection with my laptop. Have taken the snapshot of the menu that I was describing .
I strongly feel you have a hardware failure rather than a simple fix and would require the help of a technician (ordinary if professional is unavailable). Am skeptic you could mend that on your own unless you are proficient in electronics. This mishap is not due to flashing wrongly too, unless you have changed the stock ROM with some custom ROM which has some bug that affect the USB alone.
Take the assistance of a technician whether professional or less is my counsel
Thank you

I did flash a different rom .. but then back to stock recently.
I can do basic electronics but the if the problem lies in Mobo .. then nothing can be done .. as I don't have the spares available in India. But I would hate to lose this phone as it was a perfect fit for my needs

Then the question of wrong flash or ROM issue does not arise

If you do not have spares is best left alone rather than tampering with it and rendering the device useless if any untoward incidents tends to occur.
But I would hate to lose this phone as it was a perfect fit for my needs
Send to the vendor directly if you have warranty for the device stating its complaints or request your relative or friends who live in the area where you bought your phone to hand it to the vendor or service technician and bear its expenses

Is there a way to unlock bootloader somehow without connecting to usb ? That would also solve the purpose.. I want to root it for some of the things to work and with the latest upgrade to latest version I lost the unlocked bootloader and root.. if somehow I can unlock and root .. I should be fine without the usb connection to computer.. but I have ran out of ways
Does Kingroot work for you?
I mean did u try it or u just want magisk?
If u didn't, kingroot may be able to root ur device and unlock ur bootloader, then u can flash TWRP using rasher.. & make a backup BTW...
After that, try using the adb sideload in TWRP to test ur connection with ur computer.
TWRP for ur device : (q.gs/DxuAH)
There is a way to unlock bootloader without USB via developers option.
Go to settings-----> About phone-----> Build number ( Tap this option around 7 or 8 times) till developers option is enabled------> go back to settings-----> developers option-----> OEM unlock option (Enable this option) to unlock the bootloader.

This gives me an frp unlock and not a phone unlock.. still not able to root
There is no FRP unlock.

There is no FRP unlock, to circumvent FRP you need to factory reset or flash your firmware. The above quotation was to unlock the boot loader as you cannot access through your computer. Your sole option to unlock boot loader was through the above directions.
Moreover, King root application never ask for boot loader to be unlocked. Although a little unstable this is the initial program to root any device. Once you have the TWRP setup then you could switch to Super Su etc. according to your preference.
Could you paste your developers option snapshot here...

My phone was Micromax and I am not aware of your phone's firmware, try and google or search the Xda developers forum under your phones model number for the original firmware.
can any one help me how
or how can fixed this problem
and i have other problem
when i try to boot to TWRP phone stay on " your device is booting now..."
Your phone has not installed TWRP duly, therefore it boots straight to the system. Search again in this XDA forum, with your pnone name and model number to obtain instructions
so any one can help me how reinstall TWRP without PC or why this problem ??

Hi guys,up front I apologize for my English.I need help with my phone S6 edge,fast charging is not working and as I understood lot of other people have the same problem(charging takes 6h 0%-100%).I also noticed the problem happened to others after updating to Nougat 7.0.I had the plan to downgrade my phone to older version of android but...as I connected my phone to PC it says Unknown USB(so ODIN can't recognize my phone) and in device manager my phone is detected as Unknown USB device(Device Descriptor Request Failed).In settings software update says I have the latest software installed and I have no option to update to newer edition.I tried factory reset,wipe cache,tested charging in safe mode,tried 2 differen't charging flex assemblys in my phone,differen't cables and charging adapters,differen't USB ports on PC,multiple samsung USB drivers...that go along with smart Switch,Kies,Kies 3...fast charging is enabeled in settings,tried turning on USB debugging,setting device as MTP in developer options...god knows what I haven't tried.Is there known problem and perhaps solution...or someone who can suggest more troubleshooting methods.I am able to open and fully disassemble the phone to check hardware if someone suggests me to check on some hardware...any ideas PLS?
