beating dead horse: cant USB sync w/ activesync

8525, sync w/ USB 5% of the time, no changes seem to change anything.
did the notification edit here on xda
uninstalled/reinstalled activesync
upgraded to 4.5
deleted partnership
uninstalled firewall
checkdisk
ran the resync program
installed office, .net 2.0, activesync 4.5 on entirely different computer
[edit: added for clarification]
tried unchecking the advanced connection box in start>settings>connections>usb to pc
[/edit]
when connecting to either computer, i get the "usb device seen" chime, but not the "i can do something with this device" jingle
get the "active sync cannot connect with this device" popup, run the diags and everything is okay. ms site politely informs me that the cause of my problem is that the device cannot connect to the pc.
anything i missed? i gave up on it 6mo ago when i got the phone bc i got bluetooth sync to work but now i want to flash to wm6
Thanks

start>settings>connections>usb to pc.
Untick the box. See if that helps?

Try this procedure step-by-step
1. make sure your phone is not connected to the computer in any way
a. Bluetooth off
b. WIFI off
c. USB cable not connected
2. Run spybot S&D (I always do this when the computer misbehaves - and make no mistake your computer is misbehaving)
3. Terminate all other running programs
4. Hook your phone to the usb cable and the usb cable to the computer. (don't worry if it syncs or not)
5. Open Device Manager and select Network Adapters
6. Uninstall the Windows Mobile Device
7. Disconnect the Phone
8. Open the Control Panel "Add/Remove Programs" and uninstall Active Sync
9. Reboot the computer
10. Connect to the internet and get a fresh copy of Activesync 4.5 and install it.
At this point if you can back up your PIM to the storage card or something it would be great because I suggest you do a hard reset of the phone. go to the settings page and select System. Tap the clear storage icon and follows the instructions to reet the phone.
11. Reset phone as above
12. When phone reboots, connect it to the computer via the usb cable.
Phone should sync from now on.
Good Luck
PS.
MrVanx is right, that could help but it will limit your phones capability. However if my method fails that may be your only option short of reflashing the phone with some other ROM.

I've tried MrVanx' solution also, just forgot it in the original post. It seems to sync more often when the box is ticked anyhow.
I don't have a problem with hard reseting or flashing. I'm going through this hassle for the sole reason of flashing to schaps 4.31
Ill try that when i get home tonight

Say I do a sprite backup before hard resetting the phone. After I do the hard reset, I restore the sprite backup. Will my lack of syncing problem come back? I assume it will.
After the hard reset and the initial sync on the "fresh WM5 install," I should proceed from there with the WM6 install, correct?

I have a TyTn II and experiencing a similar problem as sook..
I did all the steps except for these:
5. Open Device Manager and select Network Adapters
6. Uninstall the Windows Mobile Device
The thing is i cant find my mobile device anywhere in the device manager or in the network adapters subcategory. Any ideas?

Yes proceed. And no I don't think the failure to sync problem is related to the backups so that should be safe

Not sure how a TyTN II looks to the device manager. try this instead:
open the device manager and click on the USB devices subcat.
Then connect your phone to the computer via the usb cable. pay attention and uninstall the usb device that appears when you hook up.
Then rescan. Reboot both the computer and the phone and see if that helps

Before you try flashing make sure you have the Hard-SPL V7 bootloader installed.
You can flash without activesync tho.... activate the bootloader and connect your usb cable. If the tricolor screen indicates a usb connection then you can run the RUU wrapper, follow the usual steps and it should flash just fine.
You activate the bootloader by pressing and holding the "Power" and "OK" buttons and depressing the reset with your stylus (the OK button you use has to be the one next to the jog wheel)

I can't find my Hermes in device manager either. I'll try doing the flash through the bootloader i guess.

Did you try un-checking the "Enable Advanced Network Functionality" box as mentioned in Reply #1? That fixed it with mine. It would sync with my WinXP work PC, but not my WinXP Home pc, unchecking that box fixed it. Been fine ever since....

AT&T 8525 USN Syncing problem ...
I had the same problem too ... fortunately I had a simple fix.
I made sure that I only use the USB/mini-USB cable that came with my AT&T 8525. If I use a USB that came from a different device (like another phone or camera), it doesn't want to sync, except once in a blue moon.
The other USB cables may charge it, but won't sync it.
I've read elsewhere in this site that our 8525's can be picky with their pinouts on the USB, so this might be the issue. I hope it's something this simple for you!
Hope this helps!

it's a thought. ill dig through my drawer of cables and pull out all the usb/mini usb cables. no idea if I'm using the original or not.
however 6 mo ago when i gave up on the thing the first time i know it was the correct cable

sometimes cables go flakey, but the cable we use is standard not proprietary so any A - miniusb cable should work.
Anyway the procedure you outlined above should have worked, am I to understand you still have the ATT ROM? If so talk to them about this problem.
If not access the bootloader again and hook up your usb cable. Does USB appear at the bottom of the screen?
Are you using the usb adapter that came with the phone? If not try to go back to that. The pinouts are the same as a miniusb but the form factor makes for a better fit and regular miniusb jacks can cause nonsyncs.
If you aren't getting "USB" at the bottom of the screen it is either a bad cable, a bad usb port (either at the comp or your phone), bad usb drivers, or just bad hardware in the phone. If any of these is the problem, all you can do is talk to AT&T hopefully before the warranty expires.
Sorry I wasn't more help mate.

The cable I've been using is the one that came with the phone. I tried the cable that came with my mp3 player and got the same results.
I do still have the out-of-the-box ATT Rom, however, the steps you outlined did not fix my problem. I did notice that my device appears as "HTC USB Sync" which I found strange. Is this normal?
USB does appear when I connect the phone in bootloader to the computer. I've tried two USB ports on two separate computers. Both computers are completely up to date with MS and drivers.
I suppose I'll go bother the people at ATT.
If I'm done with the ATT Rom, can I do all the flashing through the USB connection to the bootloader?

hey guys im having the same problem (TyTN II) it'll charge, but wont sync or show in device manager (i am using the original cable though)
i've tried to go into bootloader, but it doesnt say 'usb' at the bottom like it should, instead it says 'serial' i've tried diff usb ports, i've also unticked the advanced network box, softreseted, and hardreseted still no go...any ideas?? (im using alex's wm6.1 rom, could wm6.1 possibly have something to do with it?)

ActiveSync BOOSTER
Is there a way to boost up speed of Sync
Is there a any software or Cab file for it ?
Also want to know after we sync Phone
It keeps repeating to sync, is there a way to stop it ?

[Q] USB-PC Not working?

I'm running OTA 4.0.3 (Acer_AV041_A500_1.033.00_PA_CUS1) rooted with I don't know what tool, but rooted after upgrading to 4.0.3, and using one of the tools found here which was the latest (at the time of rooting). The tablet has an "A500 Root Tools" app which has options to enter APX mode amongst other things.
I'm unable to get my Acer to connect to my PC via USB. I tried using both a mini(?)-usb cable and an A-A cable. My acer makes no notification, and there's no visible, or audible, evidence that anything was connected. USB Debugging enabled and disabled makes no difference. The tablet shows absolutely no sign that anything was plugged in. Nothing in notifications, nothing in any file managers.
Likewise on both a Windows 7 PC, and a Windows Vista machine. No little sound saying I plugged something in. Nothing listed in device manager. Nothing anywhere. The Win7 machine has the Acer drivers installed, as it is the machine I used to root it a few months ago.
Is there some weird ICS toggle that I need to perform to get this working? I know my USB ports are working as I've plugged in USB sticks and it mounts them without issue.
At the end of the day, I'm just wanting to flash my bootloader so that I can install CWM and a custom ROM. If there's a way to do that without needing my PC connected, that would make me equally happy.

Reinstall the Acer Drivers and also the Google drivers from the android sdk if u have that installed, if not use the adb_fast.zip attached. For you to successfully flash the BL do not underestimate the importance of having the drivers correctly installed - its the cause of 90% of the problems folks have had - my advice is to keep Device Manager open the whole time so you can see what is or isn't installing - dont proceed with the flash until you are sure they are - else you'll be looking at a downgrade to HC to fix things
you can also use Acer Recovery Installer from the market to install a custom recovery

While I appreciate your help, my issue is not drivers - Windows isn't loading the wrong drivers, or no drivers at all. Windows is showing no sign at all, at all, in device manger, any where, that a tablet has been plugged in. Like wise, the tablet gives ZERO notifications on being plugged in to a PC. Nothing. No sounds. No notification. Nothing.
I was originally using the micro(?) usb slot, and it was not working. I assumed that USB slot was dead. So I went and bought a USB A-A cable - after testing the normal USB slot and established it works - and it, too, does absolutely nothing when plugging the device into a PC.
I've since tested with an Ubuntu 12.04 machine as well. dmesg lists nothing.

and the adb interface driver thats not showing in device manager?? and you have the acer drivers installed??
All the signs are pointing to no drivers, failing that its sounding like a hardware issue either yr tab or cable - can u try on another pc/laptop?

Tested it on a Win 7 Dell, on a Vista Dell, and on an Ubuntu 12.04 Compaq. None show any sign of the device being connected.
I know my *two* micro USB cords work as my Nooks (color and tablet) have no problem with them. I know the large USB slot works as I've plugged in a keyboard and a USB memory stick and both are immediately detected by android.
I've also done a factory reset on the tab. Problem persists, obviously.
I'm actually setting up stock Win7 on another laptop right now. When it's complete I'll install acer drivers and plug in the tablet. It will be the only USB device, let alone android, to ever be plugged in to it.

The tool you used to root it (icsRoot) also has an unroot tool, which you could have used...I have tried to unroot manually which wasnt easy as I had a pre-rooted rom and I had real trouble getting rid of superuser, but in your case it may be a bit different....Sorry can't give you much help in the unrooting ics dept. Maybe try flashing acer stock rom??? or starting a new thread??

are you trying to flash something or do you mean when you connect yr tab
windowz explorer doesnt show your int/ext storage??
more info needed, what rom and bootloader, what OS on yr pc can u try on a different one, try a different cable and usb port..
have you run the acer drivers setup.exe
did u install the android usb ones
have u opened a command prompt from the folder where adb.exe is and run "adb devices"...does a number show??
when u have device manager open and connect yr cable do you see the drivers install. If they are there then uninstall them, disconnect yr cable and clean boot and reconnect.
If they do not install then manually install by pointing them to the folder you extracted the zip to...for the acer ones, just point it to your c: drive
If windows trys to install them, stop the hardware wizard from searching windows update and manually install them yourself.
If you've tried to flash the bootloader and it hasnt completed for what ever reason - you can strike issues such as yours - again, uninstall, clean boot, reconnect, manual install

That's correct, a straight USB "A to A" won't work. Further, I discovered something else; not all micro-usb cables are created equally! I was using a cable that worked fine on my Thunderbolt phone, would not work at all on my A500. Turned out there's some enhancements to the pinouts on the newer micro-usb devices. So the lesson here is go with the cable that came with the device if at all possible.
Seriously though, give a different micro-usb cable a shot; they're pretty cheap around the interwebz.

[Q] PhoneUtil oder UART/USB option ... to get USB working?

hi there,
thanks for the great omniROM, i use it a while now and I was never so happy with my Galaxy Note N7000!
running the latest 4.4.2 (20140329) and have a SDcard in slot working properly.
I upgraded from stock 4.1.2 and it was an better experience than ever before, but there is just one thing that bothers me: USB Connection
when I connect an USBStick via OTG or via USBcable to PC, the only thing that happens is charging. this appeared some while ago still in StockROM after excessive use of USBSticks (all FAT) and keyboards. I was hoping the rooting and upgrading to OmniRom would 'reset' this behaviour, but it didn't tried differend tools, some with SU and nothing worked.
so my questions is: how can I get into the PhoneUtil-menu in omnirom or the UART/USB option?
after researching some more, I found this similar case and (possible?) solution. i'm keeping some hopes in this to get USBtransfer working with USBsticks again:
........ GT-7000 USB Data connection not working
My phone was not detected as MTP by the computer.
My phone didn't detect that it was attached to a PC.
On my PC --It didn't work.
Another PC --It didn't work.
Even another PC --It didn't work.
Mac --It didn't work.
Tried all sorts of things written on many websites. --It didn't work.
There was no MTP option in the status bar. It just always charged using the PC.
THEN... Finally 1 day, when I was looking at the back of my CPU (PC ) I saw my USB 3.0 Ports (the Blue ones). I had never connected anything to them. So,
Tried on a USB 3.0 Port --It WORKED!
My phone was immediately detected as MTP. The option showed up in the status bar. I could transfer files. But then- What about my USB 2.0 Ports?
Then I did the following :
Dialed *#7248# for the PhoneUtil options.
Under 'UART' tap MODEM. Under USB, PDA.
If this is already your setting, choose the another ones (PDA for UART and MODEM for USB) and then tap SAVE and RESET.
Again dial *#7248# for the PhoneUtil options.
Under 'UART' tap MODEM. Under USB, PDA. Finally tap SAVE and RESET.
Your phone will now be detected as MTP with all types of USB Ports now.
thanks and best regards

Android File Transfer on Mac not working correctly-- any ideas?

Here's the situation. LG G6 us997, oem unlocked but not rooted. USB debugging is enabled and File Transfer (MTP) is the selected mode.
When I connect via USB to my MacBook pro (running osx 10.12), I am able to use adb to connect to my phone (push/pull files, etc). I am also able to connect to LG Bridge to initiate wifi file transfer (i.e. it recognizes my phone via USB).
However, when I open Android File Transfer it gives me a No Device Found error. If I switch the USB mode on the phone to "charging" and open AFT, I am given an error that suggests it sees the phone but knows it's not in File Transfer mode. It tells me to switch to MTP and reconnect, but then I again get the No Device Found error.
Here's the really strange thing. I performed two experiments. First, I plugged my G6 into another Mac (a mini) that had Android File Transfer installed, and instantly the file explorer popped up, working perfectly. That suggests to me that my cable isn't bad, and that my phone settings are probably okay.
But then I plugged my friend's Samsung Galaxy S6 into MY computer, and Android File Transfer popped open as it should, working perfectly. I'm not sure what this suggests. The weird thing about THAT is that plugging that same S6 into the afformentioned Mac Mini does NOT work!
So I'm stumped. I can always push/pull files via adb, but sometimes I want the simplicity of a drag and drop GUI, you know? A little more info: I think LG Bridge and AFT (and LG pc suite which doesn't work) can conflict, so I've definitely uninstalled those applications to minimize variables, rebooting between tests. I've also rebooted my phone between changes, and locked and unlocked it, and toggled File Tansfer to Charging modes repeatedly, and plugged and unplugged the cable, tried different usb ports, and switched cables.
Any ideas?

T95MAX Android12 Allwinner H618

Hello,
I bought the android box 12 T95MAX H618, the box boot looped when I received it (it turns on and after 5 seconds restarts).
I managed to get the stock firmware and I reflash it with Pheonix card, but it continues, if I unplug the box or leave it off for more than 5 seconds it boots in a loop.
I tried to connect the ox to the pc with phoenix suit and phoenix USB pro but they do not detect my box, while in windows it detects the box but marks me as an unknown device.
Do you have a solution to stop restarting in a loop?

which Android version? can you show pictures of the tvbox?

and the stock firmware link: https://mega.nz/file/Vpsl1RQQ#pwUFrrZOGTgvzjoUpuoOHiO9dG3UkwWRB5V7bBDaDVU

I can't connect the box to the pc, I use a usb A -> usb A cable.
1 I connect the usb port on the pc but not the boxing and I disconnect all the other cables.
2 I keep pressing the reset button in the AV port
3 I connect the usb port on the box
I hear a sound like what the box are plug and in the device manager I see this:
"Unknown USB device: Device descriptor request failed"
Everything I tried but didn't work.
- Connected turn on usb debugging mode
-All the usb ports of the pc
-Install drivers
Do you have a solution I'm desperate

first thing you need plugin your box again to the computer, then you need to start to remove all unknown usb devices from your device manager, you may need to click on "view > show hidden devices" in device manager to see all unknown usb devices, remove them all, then disconnect your box.
if you have anything in your programs related to drivers for your box, uninstall them before you plug the box back in.
if this is a desktop computer, try to avoid front usb ports if possible.
if you have a second A-A USB cable, test with that if possible.
now before you plugin your box, you need to install the correct drivers, normally the manufacturer or your supplier can give you those, don't download any random T95Max drivers online because there are at least 3 different models of T95Max tvboxes as far as I know, and yours is a newer model.
after installing the drivers, then follow these steps exactly:
- unplug all cables from the tvbox
- plug in one end of the USB cable to the computer only
- have the firmware flashing software open
- press and hold the reset button which is usually placed inside the AV port in most boxes
- while holding the reset button, plugin only the USB cable, then release the reset button
if it's detected correctly, you can move on with the rest of the steps, if it's not detected, then unplug it and repeat the steps but this time plug the USB cable to a different port on the tv box, because not all ports support firmware flashing.
- i'm sure you know the remaining steps since you have the firmware and probably the software for flashing the firmware.
if you try all ports on the tv box and still not working, I would probably still try on a different computer, if that fails as well, then all I could say it might be a defective box, you could maybe try the sdcard method if possible on your tv box, or contact the supplier where you got it from
good luck

my box t95MAX is well detected by my pc but in the device manager there is written
"Unknown USB device: Device descriptor request failed"
How to solve this problem?
Maybe I need special drivers?

My friend, this exactly means it's the drivers aren't installed, that's why I sent you the steps you need to follow.
Also you can't say it's well detected if it shows unknown usb device in control panel, hearing your computer making a ding sound doesn't always mean it's a good thing

I bought this same exact box, but my issue has been not being able to install Teamviewer QS nor the Host file. I downloaded that stock firmware image and tried burning it onto a microSD card, but I kept getting failed to load error. After doing further research, it turns out you need to install MS Visual C++ Redistributal Runtimes. I downloaded the all in one file which installs all the Redistributal files.
Then using PhoenixCard Tool (v4.24), I burned the image onto the microSD card. BTW, when the process is done, you'll see many partitions were created on the card. I unplugged the power to the box, popped in the microSD card, plugged the power back in and upgrade process automatically started. It booted back up, screen loaded up all the software and all was running. Teamviewer apps still won't run though.
I wish there was a way to downgrade to Android 11, 10, or even 9. Good luck!
