[Q] WinMo wont connect via USB since new Froyo installed.

I was trying to put the hum/hiss sound fix on my sd card and I cannot get my pc to connect via USB...
My wife has a TP2 and it connects fine...
I have tried with/without the sd card in, rebooted the pc and phone, rebooted the phone while connected to the pc.... nothing...
wtf...
anyone else with this problem?
PS... NRGZ28 had posted a very basic rom for booting to android back in Feb and it is now gone from hotfile. Anyone know of a quick boot into android?

- Try a different computer
- Try a hard reset
That are the first thing you should do.

Tried hard reset...
Dif PC is not an option at the moment... I have rebooted...

Just flashed the ROM (NRGZ newest, thank goodness I had it on my SD card) and I still cant get it to sync...
I have attached the USB error I am getting... (Win7, new install)
The phone is not asking if I want to active sync or use as storage???? wtf...

Reboot your PC? lol bet your tried that already...
Try this:
settings > connections > usb to pc > and disable Faster Data Sync then try. This way uses the generic usb drivers and maybe it will connect.

That did not work...
How do I get my Win7 laptop to see the phone with Android on it?

dont think thats working yet

Ya I don't think that works yet, it's tied to Android software drivers and the use of the USB port, since there is no drivers to control the port only to charge battery. Windows thinks there is something there, but the phones USB can't communicate back....I think this is the issue or at lease after playing around with it on my phone anyway

Not that it's a huge amount of help but might troubleshoot down to the hardware level...if you go into bootloader mode on the phone and connect to USB does it connect?

I don't think you should go that deep and dirty. My touch pro 2 works only with only 1 (non-HTC) cable of the 10 i have at home, all are the "standard" mini-USB but only one works flawlessly for communicating/flashing/syncing, the other cables either do the same error - device not recognized - or windows says that the device could communicate faster - and only copies files slowly.
All in all: you should simply check with another USB cable or if you have the factory HTC cable try it with that. I noticed that the cable i am using other than the HTC one is a very good quality thick (low-resistance and double-shielded) USB cable and it never failed on me.
One other thing you should definitely watch for: plug the USB cable into the motherboard USB port directly (on the back of the PC where you plug the keyboard, mouse etc.), sometimes PC cases with front panel USB outputs simply die, or are wrongly attached to the motherboard USB header and it can cause the aforementioned problems too, not to mention if it is wrongly attached it could harm your phone too.

[Q] CM7: "Connect to pc" menu missing

Hi,
Apparently I can not post on the appropriate thread, so I'll have to create a new thread here.
I'm using the latest CM v7.0.3 rom and the "connect to pc" menu is missing. No "mount as harddisk", no "charge only". I can not access my SD card from the pc at all. Am I missing something? Reboot and/or connecting and disconnecting my device multiple times to different PCs didn't help either.
Thanks for any help,

Umm, when you connect your phone via usb to the pc, the usb icon and usb connected msg should popup, slide down the status bar, tap the usb connected notification and then pick turn on usb storage , the phone is already charging when connected to usb so you don't get that charge only option

Well yes, that's what it should be like - but exactly that notification is missing. It's been there in previous versions of CM/HTC Sense, but I don't get that pop-up in the latest CM703...

usb / connect to pc menu missing
i have the same problem on my legend with CM710 stable...
i remember this option was there (and a menu popped up when you plugged it in) but now it is not there anymore and nothing happens when i plug it in (windows: usb dev not recognized, ubuntu doesnt even recognize any usb device)... although the phone continues to charge...
i suspect that i might have done a factory reset or something after which this problem started... (or i may have disassembled the phone to replace the touchscreen/lcd... but has been carefully reassembled and everything else works fine..)
even tried to recover to old backups, flashing the rom again but nothing happens, still no connect to pc menu in settings nor does pluggin it in works...
gonna try to flash a stock froyo rom and see what happens..
if i am missing anything then please let me know...

For USB Storage mode:
1. Disconnect
2. Settings->Wireless and network->USB utilities
3. Click button: Connect storage to PC
4. Plug in USB Cable
I hope it helps.

Do you mean adb connection or usb mass storage one?
I don't know whether you've checked this yet, but try this:
if you mean the adb, on the home screen, press: menu>setting>applications>development>check on usb debugging
if it is usb storage, refer to what mayerkemp said
or if you can see usb logo on notification bar, slide it down and tap connect storage to pc

Thanks guys,
Problem is that when I click on connect storage it either says "connect the cable to use mass storage" or if the cable is connected it says "USB is connected. Remove the cable."
Any thoughts?

Hi guy's, so I've reinstalled a backed up rom and it's fine now.

Just always check development mode on application setting, then u can change to usb storage with tap usb connected from expanded status bar, that's what I do on DXLM3
Sorry for my bad english

[Q] USB stopped working 4.3

Hi all, how are you?
I have a Galaxy Nexus unrooted stock with Android 4.3 (JWR66V).
After the update to 4.3, my device has stopped working in MTP/PTP mode.
I mean, When I connect my phone to my Notebook USB port, thus nothing happens on my notebook or my phone.
When my phone is connected to my notebook the notification dialog to select between MTP/PTP modes doesn`t show up anymore in the phone (it only says that is charging).
I have tried to re-install the drivers on my notebook, and It didn't fix this issue.
I have also tried to the a factory reset on my phone, and It did't fix the issue either.
Besides, I tried also to connect the phone with a different USB cable and it didn't fix the issue either.
Please, May someone help me?
Thanks in advance

Please, May someone help me?
I have no idea of what is going on and why USB stopped working after 4.3 update?
How do I troubleshoot this issue?any clues?

I figure out that on Android 4.3 I have ti go to Settings->Storage->Usb Computer Connection and manually select the connection mode...
(I am not sure Why the notification pop up doesn't show anymore on the phone when I connect it to the PC using the USB cable)

You are totally right... dont know the stu... option doesnt appears clear. On my S3 I did the same, but the option wasnt visible... you must click over USB (even it appearing as dimmed) then a USB CONNECTION (or something like) appears you must click over and then a screen with MPT option will be available... For godsake WHY such thing isnt available on settings or on shortcut menu by default is beyond my understanding.

[Q] S4 Mini does not recognise PC via USB anymore

Hello everyone,
when I tried to connect my Galaxy S4 Mini (LTE i9195, Stock KitKat, rooted) via USB to my computer today, nothing happend. I checked the drivers, they are all installed. But I can connect another S4 Mini (LTE) without any problems.
I noticed that my S4 Mini does not show the notification you usually get when you connect the phone via USB (the one where you can choose Camera or MTP) anymore. The other one, which works perfect, shows this notification in the notification bar. I am using the original Samsung cable, which was shipped with the phone.
Note: My phone still charges when I connect it to the PC but does not recognise the PC connection
My phone is rooted and I used an Autostart/Reciever Toggle program yesterday - is it possible that I accidentally deactivated a necessary service?
What I tried so far:
- Google (only found solutions for "PC doesnt recognise phone" and not vice versa)
- Reboot
- DalvikCache Reset
- Cache Reset
- turn on/off USB Debugging
- use different cable
- use different usb ports
- use the code *#8080# to change MTP (it was already set to MTP...)
#Edit: It is just as in this thread (but S4 Mini instead of S4):

Thanks for your answer, but I can't find what you mean I have seen a post where it says that I need to go to Settings -> Storage and hit the three dots there, but on my Samsung there are no 3 dots AND nothing happens when I press the menu button either... See: random-host.com/blogs/enable-media-device-mtp-usb-mode-android-44-kitkat-and-50-lollipop
Thanks!

(Okay I got it working now.)
After I tried everything I could imagine, I decided to Flash the Stock Rom again. But before I was going to flash the new ROM I did a nandroid backup with CWM of my current ROM + everything. After Full Wiping I decided to restore the backup I just did (the ROM is still downloading hehe...) and voila it works again! Why? I have no clue...
So just backup -> full wipe -> restore backup -> worked!
#Edit: Stopped working agin... But the computer successfully connected to the phone, installed the drivers and displayed the phone in the explorer. Note: this time (when it actually worked after the restore) it showed the MTP connection in the statusbar! But now it disappeard again and is not showing up anymore...

Have u enable developer option ?? Some phones needs to enable developer optiom to recognise the phone in pc.. to enable this go to setting /about phone n click in build number more than 7 times . And then go to developer optiongn then click in USB Debugging . Then ur pc will recognise the phone.. hope this help u !!

Thanks for your reply!
As stated in my thread I already enabled/disabled and reenabled USB Debugging, and USB Debugging requires Developer Options.
But thanks for trying to help!!
Is it possible that my USB port is broken? A new one only costs 5€ so I think I'll give it a try...

Hi ! Ive the same problem... Ive you try to change your Kernel ?

I'm currently running on CM 12 and it works. However, if the pc does not recognise the phone, try rebooting your computer and your phone (that often actually works).

Mh... Try to reboot in recovery and make a wipe data / factory reset.

Any new ideas how to resolve this issue?
Did all of the above plus factory reset, tried different drivers and changed phone's charging port.
Two other phones (a Samsung and a Sony) connect to this PC just fine.
Thanks in advance
LE: In download mode the PC sees it in Odin. I tried SilviuMik's different kernel variants (the phone is stock KitKat), but nothing happens. I had no problems with it connecting to PC until about 2-3 weeks ago.
