I flashed a custom rom a couple of months back. That rom was android version 2.3.5.
Now when I try and connect my phone to my pc using the standard usb cable, it only charges but no connection.
I did some reading before I posted and found several methods to try out
1.Use kies, download drivers
2.Enable USB Debugging mode
3.Go to settings-wireless and network-usb utilities and connect it through there.
None of the methods mentioned above worked.
So my questions to you guys are
1. Does this problem have to do with the custom rom?
2. Can I degrade to the stock rom without the use of an USB cable?
2b Can I update to another custom rom (because the phone charges when it is connected to the pc, even though I cant see it on "my computer", it should still be considered as connected?) ?
3. Which is the best custom rom out right now (Speed and performance wise)
*Side note - I know people prefer different custom roms based on their taste, but I really want to think what you guys think about which one I should upgrade to!!! I also might want to overclock to 1.6 and root the phone in the coming week if I can solve my usb problem!
Have you tried using SwiFTP app on your phone and Filezilla on your pc, then you can transfer files wirelessly

Yes I have but it wasn't what I was looking for. My phone randomly gets usb connected and starts charging without the cable being connected???
I went to the retail store I bought it from and he said you should degrade your firmware and see if the problem goes away, if it doesnt we send it in for repair.
But how can I do that if my usb only charges when I connect to the pc?
There is a Mobile Odin apk. Perhaps you could install that then flash stock firmware with it. You would have to get the .tar onto your phone though.
Unfortunately, if I´m not wrong your trobule seems to be a hardward issue.
My cell phone began a couple of weeks ago with the same problem, and it became even rather serious. Some days ago it didn´t charged if I connected the charger when it was on. I should switch it off and then connect the charger, having done this, the cell rebooted by itsefl and then began charging.
But, just seeking and testing I bought a "charger block replacement" in ebay and replaced it by myself. It is not complex to do it on your own... today I am happyy.. cause I fixed it..
If your problem continue.. I hope you will remember my words!
Hello to all since this is my first post on these forums! And to just say thank you to everyone who will respond to me if I don't say it.
I rooted and installed CWM 6.0.1.8 on my phone about a year ago. I did not unlock the boot loader, because I didn't want to have any custom ROMs on my phone. Now just recently I was looking at android 4.4 and thought that this is a good update for any phone. So, I started to do my research for what to do to flash a ROM. I downloaded CWM 6.0.4.5 on my micro SD card and used "[ROOT]Recovery Tools - Flasher". Now this is where everything goes south...
I went through the app, found the CWM file to flash, and then I got the security error... After researching why this happened it was because of not unlocking the boot loader which was a huge mistake that I forgot to do.
I have searched on here a lot. I found a lot of great and useful information, but I can't try any of the suggestions yet. Not until my computer can recognize my phone. I know before this all happened, I had debugging enabled on my phone. I do not have fastboot installed on my computer anymore (reformatted a long time ago). I do have B2CApp.exe installed so I could try to do a factory reset on my phone. I have installed the driver for the phone from the LG program and from their website.
But like I said before, when I plug in my phone to my computer, the computer does nothing. It doesn't recognize that there is even a device there, but there is power getting to it. How I know is because I took out the battery and "S/W Upgrading" could be enabled.
If I can get past this, I'm 100% positive I can fix it then. If anyone has some sort of useful information about my computer not recognizing my phone, please share it! Also, for context, my computer is a windows 7 x64.
Thank you for your time and your responses!

Well I haven't heard from anyone yet and I've been still digging around. I might know why my computer doesn't discover my phone. I think it has to do with the charging port. It makes sense since that is where the connection lies. And I already know that my cords are all good as well as my computers. But anyways, I have bought a replacement part and hopefully that fixes the issue.
I'll post my results as soon as I replace the part. Wish me luck!!

Hi , guy's , i cant find any other solutions on the net. i have an s6 edge that can't be recognized by the pc or mac, i tried everything all drivers, smart switch , kies, different pc's and mac, different cables, debugging mode on and off , but nothing worked, i even changed the entire USB-dock of the phone thinking it was faulty by a new one but its the same thing ( not recognized ) and by the way the phone can't " rapid-charge " both on the old and new usb-dock's , I tried the same aukey fast charging adapter on another s6 and it worked , my last hope now is the battery i know it may sound a little bit ridiculous but the phone has been exposed too much to hot sun the last summer so the battery inflated and pushed the back cover of my s6 edge , i thought maybe somehow it's because of this incident that the phone is not recognized by the pc , and that it couldn't get the "rapid-charging "
( note : that i had never connected the phone to a pc or had a rapid-charging adapter before the battery incident, so i couldn't know if the phone worked on the pc or could rapid-charge before or not "when the battery was ok ") .
am going to replace it ( the battery )in 3 days from the posting date of this thread and see what happens but please if you have a solution just let me now as soon as possible
Thank you very much ! .
In what condition is your phone? Does it work? Or is it dead or half dead?
Samsung Kies doesn't work anymore for S6 and S6 Edge!
S6 and s6 Edge = Smart Switch.
Enable smart switch on your device first before plugging it into a computer..
By the way, why do you even want to use Smart Switch or Kies or whatever?
What is your issue?
Btw, if you knew that your battery was inflated? Then why did you replaced the USB port instead of the battery?
The USB port should be long lasting for aslong as you haven't spilled anything on it or damaged it in one way or another, you couldn't damage the USB port unknowingly..
Hi, first of all thank you for your answer.
So my phone is in perfect condition and work great exept for the problem that i had mentionned above , i didn't know that kies does not work anymore, and i didn't know that i must enable smart switch on my phone first, i just knew that you can install it on pc (so it can install the samsung drivers) then you plug your device, my issue is that my phone get detected but does not get recognized by the pc like i mentionned above i did not know that the battery was inflated only after when i opened the phone to change the usb dock that i though was faulty because the phone did not want to sync with any pc . By the way i did change the battery by a new one today but the phone still wont sync and it still refuse to fast charge, i tried everything i don't know what to do anymore.
Thank you.
1st thing you must do to get the device to be detected by your computer, and so that you could get into your phone files through my computer is to download the drivers, they come with samsung kies, so you probably already have them installed.
2. Go into your computer task manager and make sure that Kies and Smart Switch are NOT RUNNING.
3. Go download official Odin 3.10.6 on this very website (XDA).
4. Run Odin as Administrator.
5. Put your device into download mode (push volume down, home and power button at the same time.)
6. Connect your device to your computer.
If Odin detected the phone and the tab turns blue? Which it should undoubtedly! UNLESS you haven't installed the drivers or your device isn't in Download mode.
7. Disconnect your device and AGAIN (push volume down, home and power button at the same time to get out of download mode.)
8. Restart your device as usual, let it boot up. In the meanwhile close Odin!
9. Do not open any Samsung program on your computer, once your device is rebooted, connect it to your computer as usual.
10. Go to "my computer" and look if you can see your device. (which should be the case)
Watch this video to enable Smart Switch on your device;
https://youtu.be/gebkpr6pMXs
You have changed the battery and dock, so this might be an uncommon software issue. So you probably want to flash your device so that you could get your fast charger to work again?
Don't become too desperate for such a minor issue, it's better to be safe than sorry.
Is your device rooted? If so you have probably already tripped Knox. In that case you would be better off using Odin to flash your device back to stock.
Note: Smart Switch doesn't flash the same rom unto your device, it might flash a rom of a different country.
(keeping in mind that i've read somewhere that Smart Switch might even trip Knox while flashing a device)
Everything is at your own risk, just as all of us.
Let us know how it goes.

I guess that your problem is solved.
For ANYONE who reads this;
When YOU get help on XDA or anywhere else and your problem is solved thanks to the help given, you MUST LEAVE A POST ON THE PAGE FOR OTHER PEOPLE WITH THE SAME PROBLEM TO SEE!
DONT BE SELFISH!
Because many people might have the same problem, and many HELPFUL PEOPLE on XDA have stopped helping YOU simply because most of you are selfish and unthankful!
IF A TOPIC ISN'T CLOSED, PEOPLE WILL START NEW TOPICS WITH THE SAME QUESTIONS AND HELPFUL PEOPLE LIKE ME WILL FALL INTO REPETITION WHICH WON'T LAST VERY LONG!!
You people should remember, that you will UNDOUBTEDLY need help in the future and you won't get any help, and karma will make sure of that.
(too deen too daan!)
Be good and honest, don't go with the flow!
am sorry for the late answer but i was on a work trip and i left my s6 at home , just got home tonight , am gonna try this tomorrow and let you informed , thank you for your help
hello there
so, i have a sony xperia z2 with a broken screen and digitizer. only the backlight is working and it seems to be a broken fuse (see this thread), so no way changing the screen could help. now i'm trying to save the data but every way seems to be an impasse eventually...
first thing i tried was to connect the phone to my screen with an otg adapter but i didn't get any visible result. i found an article saying that one needs to activate screen mirroring first but that was for the z2 tablet. does that apply for the phone, too or should it work and the adapter is just broken?
2nd thing i tried was to flash custom recovery hoping i could later pull the data with adb. i followed the instructions to unlock the bootloader here but appearently usb debugging needs to be activated for that, too? at least fastboot doesn't recognize any device so far.
i also tried mirroring the screen on my computer with seven-square but that too needs usb debugging.
is there any way to get the data off the phone? anything that could be worth trying?
i'm currently working on a linux mint pc but if anyone has suggestions that only work with windows that would be helpful, too since i also got windows 7.
thanks for all effort!
p.s: i'm new to this board but i promise i will regularly follow this thread and won't leave without letting you know if the problem got resolved...
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.

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

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

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.

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...
