my XZ won't have stable connection to pc - Xperia Z Q&A, Help & Troubleshooting

My xz is charging in the wall charger normally but when I plugged it to my laptop it will connect.for.a.second and will disconnect.right away, sometimes it shows the notification of being connected to.dock even if I don't have a dock. Now I can't root my phone since it will disconnect-reconnect . I tried to uninstall everything,.I reformatted my laptop and install the pic. I did also the suspect repair and even the flashtool.. Btw if I will connect it in flashtool, the flashtool will recognize it and I can flash fw, unlike if it is on, the problem will appear. I also tried changing the usbftsetting but still failed
Things that I have tried
Reformat my laptop. Did a fresh installation
Change usb settings
Tried my usb to other phone and it worked normally
Change ports.failed
Switched back and forth from different ftf ROM
ROMS
It made me wonder why does the my xz works in flashtool.with flashtool but not while it is on, it doesn't have a stable connection to the laptop

USB connection to PC not working

My phone was working perfectly until a few days ago when I noticed that USB connection to PC stopped working. I was running imilkas CM9 v2. USB used to work perfectly and then randomly, it just stopped working, I don't have a clue what caused it because I did not flash anything on the phone.
When I connect my Phone to the Computer via USB cable, my phone start charging and nothing else happens. My computer does not even show that I connected a USB device.
I've tried 3 other computers with the drivers and the same issue (1 comp with xp and the others with win 7). Also, not to mention, I've tried multiple USB cables, including the original. I've tried USB Debugging on and off, doesn't make a difference.
I've tried ADB and it does not recognize the device either.
In CWM when I mount USB storage, it does not work.
In download mode, when I plug in the cable, nothing happens, odin does not detect any connection.
USB connection to the computer is Dead and it does nothing but charge my phone.
Here is a list of things I've already tried to fix the issue:
1. Factory Reset.
2. Used Mobile Odin, reverted to my Phone's Stock GB ROM (KK2). On stock GB, I tried Kies Air and that worked fine, but USB connection had the same issue
3. Formatted the Internal Storage
4. Removed the SIM Card and Micro SD card, still no luck.
5. re-installed CWM (without pc)
6. Installed Paranoid Android 0.2
7. Called Samsung... They said they wont service my phone because I'm located in Canada and I have the International Note. They told me I'd have to take it to the country I bought it from.
If anyone can offer any help that would be great.
Thanks in advance.

As I have mentioned in my post that I've already tried multiple different cables, including the original.
Could be factory defect. flash original rom and take it to service center.

Phone used to work perfectly fine before. Already flashed original rom, it did nothing. And I've already talked to Samsung. They won't help me.
I've already mentioned that in my op! I would be nice to hear suggestions/solutions other than the ones I've mentioned.
Can anyone please help me out with this? I even tried cleaning the usb port a bit more, but no avail. I am guessing the file that recognizes a PC connection got corrupted some how. Anyone know how to update or replace that?

Make sure the cable is properly connected. Check for dust that might prevent it going in properly. Try a different cable. What OS are you using? I found where bootloader is dmg or incomplete Windows fails to detect it. Linux on the other hand detects it. Can't use it but you can detect it.
Can you connect to SW Update Mode? Battery out and plug into PC while holding vol up button.
If nothing works try taking it into the shop.

You can root your phone from there. If you have SW Update. I recommend taking it into the shop if you are still under warranty, If you don't have warranty then you can go ahead and root. Just install a patched bin and fls with Smart Flash Tool. It's one of the stickies (How to unbrick, I think)
hi
new to Android nation
I have the same issue when connecting to USB...
And I managed to flash with custom firmware (latest ZEUS version) and I rooted but the issue with USB connection is still there...
Anyway, I wiil try connecting it to Linux to check if that would work with USB connecting
UPDATE:
OK after some digging, I managed to (at least temporally) solve the issue... After fresh installing official 2.3.4 firmware I booted to recovery and from there formatted the system folder and then installed Zeus v7 firmware... anyway, USB connection and charging indicator work fine at first booting to system... As soon as I reboot the OS USB connection (and charging) get unstable, and after third reboot it completely goes away and the device does not recognize anything: if I connect USB cable it does not show any sing (charging indicator does not show battery charging, nor the device offers me to connect in mass storage, windows recognizes only modem but not the USB storage) and when I connect charger, battery indicator does not flash as charging... Battery monitor tool shows that "battery is discharging" even though the battery capacity seems to increase (according to growing percentage of battery capacity)... Is there a some kind of USB server... I am a total noob to Androiid OS (used to be Symibian from its beggining )so I hope you won`t mind if I used wrong terms in my explanation/comment...
I hope my explanation is not confusing
Cheers
UPDATE 2:
After installing Zeus v7.01 update, battery charging recognition got fixed using both USB cable and wall charger...
Anyway, USB recognition by PC problem still exists... But when in recovery mode I can successfully mount SD card to PC in Mass storage mode...
Will keep you updated... :victory:

[Q] USB not functioning - intermittent ADB

Hi guys, hoping someone can help ?
As you see from the title, my HTC One fails to connect to the computer, Here's what ive done to try and remedie the problem.
Removed and clean installed latest HTC Sync and drivers
removed SDK and ADB, updated
rebooted phone
switched on and off
tried several roms
tried 3 different usb cables
tried 5 different usb ports
tried 2 different PC's
My phone sounds like it tries to connect to the pc - with the typical windows noise, then disconnects almost immediaetly, then reconnects then just keeps doing that, my pc comes up with installing drivers, then fails to instal drivers, saying phone not connected, once ive tried this once the phone need to be rebooted before it will attemp to connect to the pc again ---- but fails again
software wise the phone runs perfectly , other than the usb connection problem and charge problem with pc.
The phone charges first time, every time with all my usb cables and htc chargers
im trying to downgrade or reflash hboot 1.55000, just incase this has somehow went corrupt on the usb commands side, but without adb ect it seems almost impossible,
have any of you guys experienced anything like this or could offer solid ideas on how to re-flash hboot from the file located on my phone ???
all help appreciated
running ardh 13.4/22.0, hboot 1.55, cid = supercid, unlocked, s-off
I would simply go back to stock and return via shop in uk - to see if i could get a replacement, but getting there seems impossible - if i can simply get the pc usb problem sorted - all will be fine

Are the chargers working fine? or are they giving you intermittent charge/no-charge cycles as well? in which case it could be your USB socket is damaged or dirty, try cleaning it with a compressed air tank (or whatever it's called )
Are you also facing the problem in bootloader mode (ie fastboot)?
hmm, will give the usb socket on my phone a clean. Im charging completley fine with chargers and usb cables from mains, when i install htc sync(latest) it installs no problems, then i plug phone into pc, the usb connected appears on phone and then disappears almost imediaetly, the pc sees ive plugged something in and straight away tries to instal drivers - but then comes up with drivers were no installed correctly, also then the phone fails to charge from pc, if i reboot phone - and plug in it will run through the same install cycle again , as described above., basically all drivers fail to install when i plug phone in, its like the phone connects then instantly disconnects.
I ll clean port and post back, could make a difference if a pin has a high resistance contact , thx for info will give it a go

That's weird. It could be possible that the ROM isn't receiving the correct input stimulus, i mean, it didn't know that a charger is plugged in.
Since you are a stock user, I'd suggest repairing the device using the Xperia Companion. You may search for the tool on Google. This is an official SONY software though, so keep your eyes so that you do not fall into malware traps!
This problem fixed after change mtp to ptp in menu setting > xperia > usb configuration. The usb work fine.
I think this problem is over, but after ubl, intsal twrp, instal cm 13, this problem is come back.
I was change usb configuration in developer options (in cm 13 roms) but not work again like stockrom 4.3
any suggestion ? i want using cm 13
i think my phone missing configuration / driver usb mtp or something u.u
after searching in google, many other sony device have same this issue...
can i go back to stock rom using twrp ? coz it was the only to installing rom.
my device cannot detect in pc
Oh well, i assumed that by "offline" charger, you meant charging the device while it is turned off.
If you could charge the device without any problems while using the wall charger, it could be possible that the problem lies on your PC. Please install appropriate Xperia SP drivers.

If the issue remains even after drivers installation, I will not be able to help you further.

USB connection dialogue not showing up, unable to connect

I have a very weird issue with my S10: it wont connect via usb to pc. Once connected a notification should display and the option "file transfer" should be there, but no such menu appears. When i plug it in to a pc it just starts charging, the pc also does not see a (bad) usb connection or whatever. I have been reading fora and watching youtube for over 1,5 hours. I feel now is the time to ask for help.
What might be usefull context: i have had the "moisture detected" error many times, it started showing up 2 weeks after i bought the device. Gladly i mainly use wireless charging so effectively it hasnt bothered me much, but it was weird since even after waiting for hours for the phone to dry (i dont think it was wet but whatever) the error was still there. One week ago the problem got quite severe, lasted for more than 24 hours and it just refused to charge, tried rebooting, turning it off, going into safe mode... to no avail. I had no wireless charger then, it was nasty.
I am using the usb cable provided by samsung (but used two others as well).
What i tried:
wiping cache and data from usb settings
wiping cache via recovery
reinstalling samsung drivers to pc
looking for a yellow exclamation mark in device manager on pc (not there)
different usb cables
different pc's
different ports on pc
rebooting the phone
booting in safe mode
installed dex on pc
via developper mode select file transfer as standard
via developper mode select any of the other modes to see if that helps
via developper mode revoked usb debugging authorizations
via developper mode enable usb debugging
The next logical step seems a factory reset. I am unwilling to do that however, since there are many gigs of photo's on the device that i want to backup first (the whole point of trying to connect it via usb heheh).
Your advice please!
Your could try to reflash your present OS via Odin but when doing so remember to use HOME_CSC. This way your data will be present when done flashing and phone reboots.

How he can do the flash with odin when phone is not recognized by the computer !
Clean the charging port with a clean toothbrush and try again ... Also make sure that the charging cable supports data transfer ... If you tried all of these things and did not work, then most likely the charging port has a problem that may be oxidized or cut in the tracks..Try the solution that I gave it to you, and if it doesn't work, take it to a technician
charge from the wall.
I too have a similar predicament. Tried all the cables and USB ports I could get my hands on... I have a custom ROM also, so it could be that. I have done a full format and reflashed ROM (from SD card) - but it made no difference, the phone refuses to communicate via USB.
SO, if you have any solutions, please let me know!
I can however communicate via ADB over network. So, if you know some adb commands you can pull over an entire folder with the "adb pull" command.
