I can't connect to active sync

Hey everyone, i just was getting ready to update to the new core rom (from xplore 1.1) and i plugged in my Tmobile mda into my pc that is running xp, and it is not connecting. When i plug it in it like doesnt even try to find it. And when it does try to find it, it just says it can't establish connection with your item.
I was using xplore and this is the first time i had this problem ever. Ive flashed 4 or 5 times and this has never happened, and thats why im posting it in the wm6 forum.
Does anyone have any ideas? HAs this happened to anyone else?
Now i am back on the newest tmobile update, and it is still doing it. Also i installed the newest version of active sync. Still no go. Also i used shell tools to put xplore on my phone, could that have left out some active sync's files? (probably not, last time i put nottosmarts rom on here everything worked perfect.
ipl 2.26
spl 2.26
gsm 02.25.11
os 2.26.10.2
love you

umm....no one?
can't someone at least flame me or something? im still stuck

I can flame you , lol
If you can't connect, how did you flashed the latest TMobile ? I am not making fun, I really want to help.

i threw it in bootloader mode. It said usb in the bottom right hand corner. It's just that activve sync is not connecting with it. i wouldnt even care, but i think you need an active connection to active sync when you flash with shell tools, which is what i do.
update: i just succesfully sync'd to my laptop running windows vista.
anichillus, do you know if shell tools will work with the new way to flash with vista?
thank you so much for reponding, i really appreciate it...a lot lol
the only reason im doing this is to get to your rom!

I really really don't know that sorry ... I am using WinXP and not shelltool.
Also, why are you using Shell Tool ? Dont't you have G3 ?
Unlock it and easy as pie. I remember papamopps saying that it is possible to flash in vista ...but i don't remember anything about shell tool ...
BTW, you have ZoneAlarm ..or similar installed to the PC where you say that it doesn't connect ? Try and disable firewall ... antivirus ..stuff like that.

well i just don't want to void my warranty, but ill definitly try turning off all the firewalls tommorow when i get a chance, i think im just going to give it a go with shell tools right now and hope for the best
Thank you so much and if you ever need anything i would love to help you in return.
you're the best!

i have the same problem..active sync doesn´t find my wizard..but it´s charging normally, but active sync doesn´t recognize it or i don´t know..what should i do?? i didn´t do any change on my pc..and before it works good..

If you're using Microsoft's OneCare then you may have to enable the Allow ActiveSync to get it to work.
Start OneCare then click the "Change OneCare settings" link on the left
Click the Firewall tab
Click the Firewall connection tool button
Place a check in the ActiveSync/Windows Mobile Device Center" checkbox
Click Okay back to the main page
Hope this helps, but like Anichillus said, it could be any other firewall application blocking it...

yes! all i had to do was turn of norton for a bit and it instantly recognized my device. I was just so confused because this has never happened before and thats why i haven't thought of such an easy explanation. Thank you both for giving me your clear thoughts! lol

Another resolution idea
I had the same issue - I would plug the device in through USB into Vista Ultimate with no results other than the bing bong noise it makes on connection. Checking the device list showed the network pieces being added, but not the actual Wizard itself in the Mobile Devices section. I could not sync, it would not pair, etc, etc.
Resolution (on the Wizard):
1) Settings->Connections->USB to PC
2) Turn off "Enable advanced network functionality"
This of course will not be the resolution for everyone, but in case someone else sees this behavior, here is a list of the symptoms I saw:
1) Plugging Wizard in via USB causes Bing Bong noise
2) wmdc shows no connection
3) device manager shows no Mobile Devices section when connected
4) device manager network adapters may show mobile device services when plugged in
5) If connected in bootloader mode the device manager will show the mobile device
6) You can set up a bluetooth connection (if available on the PC) and sync properly with it
Cheers,

Shoogi, what an awesome first post! Worked perfect for me! Keep it up, great post and lots of help!

i have a problem that when I plug my device active sync connect it and charging starts but after a minute or so active sync disconnected and charging also stoped.
I have installed everything official > rom,radio,ipl/spl etc.

One Care made activesync almost unusable for me. I also had to reflash from THT's rom because I couldn't connect at all unless I hard reset. Makes no sense cause my husband can sync and he had the identical same rom.

I think I bricked my HTC Touch Pro 2 HELPPPPPPP!P!!P!PP!!3$%^&?

Alright so I was trying to update the rom on my phone to no avail, always the damn program (custom ruu.exe) came up on the last screen displaying error 262 (update error) which is VERY common.
So I find in multiple forums of people recommending a certain update of the diamond phone series, I dont know why the f^*( I tried it, halfway in the update the phone went dark, and now wont turn on AT ALL.
I try the soft reset, battery out for a while, reinstall active sync, try in different pc's (win7 64bit, xp 32bit) no hope so far.... Well the ONLY sign of life is when I plug the phone via usb cable to either PC there is a hardware detected under "Qualcomm CDMA technologies MSM"
I believe its some sort of diagnostic mode to access the phone, but I cannot find drivers ANYWHERE! Please folks help me out is this thing done? is there hope?
PS i tried to update the drive on the Qualcomm device to wince usb (HTC USB SYNC) and it will install, however since IM NOT ABLE to go in the bootloader what else can i try?
i cannot access the bootloader & phone would not turn on.

I hate to be the one to tell you this, but sounds like your only hope lies in using jtag (which is not easy or cheap, could try a warrenty exchange.)

You could also put it in a microwave, or hook it up to a car battery, say it fried it self, then get a new on warranty

so you guys are telling me theres 100% nothing i can do?

so you flash a diamond gsm rom on cdma rhodium your device is one expensife brick its not easy to unbrick it best you can do is say you charge it all night and found not working in the morning send it in for repair and hope you get new one
a good advice read read read before even trying it always be shore

threads like this should get pinned for eternity.

hah i was thinking something like that, except that i just noticed battery low before sleeping, seemed drained in morning, wont turn on now, tried a friends battery and same problem.
PS: the main reason this happened and propably similar threads, is because there are notices to UPDATE YOUR TP2 with a DIAMOND UNLOCKER which misleads us novice users! its a shame for this to happen to such an expensive phone, and i wont usually do what ill attempt, but cant repay this company $600 for a simple fix for them.

[Q] Update error 801812C

Hi
My beloved HTC HD7 on O2 (Unlocked now) advises me that their is an update.
I imagine this is the pre-update to the No-Do update
However everytime i try to install i get to stage 6 and then the error 801812C is reported.
I have searched this and found the same answer in every article regarding-
"During Step 6 (Rebooting your phone), your Windows OS detects your phone as a new device and starts searching for driver updates online. This can be seen when you click on the little indicator with a spinning green circle in the bottom-right corner of your desktop called the notification area (you might need to click on Show Hidden Icons if it's hidden)."
"You have to *immediately* click on "Skip Obtaining Device Software Online" or Zune will time-out and show error 801812C1"
However i see no option come up on XP to allow me to stop such device updates. And i definatly have no hidden icons!
Someone please help with a better solution...
Jayne (Yes i am a girl so be nice, so sartactic answers please, I am Tech savvy but this one eludes me)

From what you post, it sounds as if maybe you have to right-click the notification icon in the system tray for that option.

From what i understand from the OP's first post, she doesn't have the icon so can't right-click it.
I know it's not really a solution, but have you tried updating on a Windows 7 machine? I've always thought that windows 7 is more compatible with WP7. I know this isn't excplicitly mentioned anywhere, but why else would the Dev Tools only be available in Win7? strange....

Windows 7
Many thanks
Yes indeed no notification is showing and I have set the taskbar not to hide inactive icons so nothing can be lurking!
I will see if i can find someone with Windows 7 as i'm a XP user through and through lol
Many thanks for the ideas so far but if anyone has another brain wave please contribute, I don't want to miss out on the proper upgrade when it arrives..this week fingers crossed eh!

same error here
Hi Jayneh,
I too have an HD7 on o2 (Sim unlocked, but stock otherwise).
I am also an XP sp3 user, and I'm getting the same error as you, 801812c1.
The update fails at step six. The phone will reboot and then show a picture on the screen suggesting I connect my phone to the pc, despite the fact it is connected already. I've tried three times with no joy so far.
I've done some searching and as you say, the current theory is that after rebooting the phone, the pc doesn't recognise it as WP7, but Wm, and proceeds to hunt for the right drivers. This will of course fail, and the update times out.
Several users on different model of phone have reported the error and Microsoft are advising you hold off updating until the issue is investigated.
A number of users are saying they are using Windows 7, so it can't be an Xp specific problem.
Several fixes have been reported by some users which include unplugging and re connecting the phone quickly, or stopping the pc hunting for non existing drivers by clicking the update icon in the notification area. This does not seem to work for everyone.
I have tried unplugging which didn't work for me. I looked for the update icon but can't see one, but in anycase, my machine runs incredibly slowly during the whole process so doing anything at all is frustrating.
One thing I haven't seen anyone reporting is whether they use the same machine to sync a WM6.1/6.5 device or not. I do, but I'm just grasping at straws here.
I'm also slightly worried as I only have a little over 10GB left on the laptop.
Here's hoping NoDo isn't a NoGo for us.
Garrickus

Many thanks Garrickus, as long as i'm not alone with this and it is being looked at, hopefully if all else fails the fab developers on here will soon have us an update rom we can port straight to our HD7's. Fingers crossed and hope the sucking up to the developers speeds this along

One solution to the 801812C1 error code
jayneh & Garrickus,
Do you have windows automatic updates turned off?
I had automatic updates turned off (XP Home 2002) and I had the same problem when I first tried updating.
After reading something elsewhere, I turned automatic updates back on and tried updating again 24 hours later. It worked, with the update running smoothly through all 9 steps without a hitch.
I don't know if you have to wait after turning automatic updates on, I just thought it would be prudent.
I'm also using an HTC HD7 on the o2 network. I hope this information helps you like it helped me.
Ian.

Automatic updates
Hi Ian,
Thanks for your feedback regarding automatic updates.
Unfortunately, I have automatic updates turned on, and PC and Zune are fully up to date, so that's not an option for me.
Interestingly, Zune had a minor update after a couple of failed phone updates and now when the little bubble pops up it describes my device as 'Zune' not 'Windows Mobile', but still getting same error code and updates fails exactly the same.
I see their is no specific response to this error code from Microsoft as yet
Are you still experiencing problems Jayneh ?
Garrickus.

Update
I was still having problems and my PC was/is up to date and automatic updates is on.
I say was because i now have the NoDo update having followed the brilliant update method by Petbede for updating without a gold card.
It went smoothly and here i am with a speedy phone and cut and paste. My god bejewelled loads so much quicker

frustration
Im using Vista, have the same problem as Garrickus. HD7 on Vodafone network. After reboot the device pops up as Zune device and computer tries to look for Zune drivers, after some time it gives up. I have tried all ways of updating drivers, nothin works.

Hi everyone,
I experienced that problem today downgrading my HD7 with Zune installed on XP SP3, three times it didn't work...then i closed all running app like firefox & other utilities...and the downgrade process worked at least...
My advice : just be patient!

Update WP7 driver on PC before running the WP7 upgrade
The error '801812C1' appears when the phone is wrongly identified as a 'Zune' device (MS MP3 reader !) after the phone restarts at step 6 of the WP7 March 2011 upgrade.
In order to set the correct WP7 device on the PC:
1. Shut down the phone (press & hold the power button)
2. Restart the phone and press & hold the camera button
3. A black screen appears on the phone showing a device connected to a PC
4. Connect the phone to PC on USB port
5. Open Device Manager on PC and check the entry for Portable Device: 'Schubert' (= HD7) or other name (depends on your phone).
6. Shut down the phone (press & hold the power button) and restart it.
7. Connect the phone to PC and run the WP7 upgrade from Zune.
The error '801812C' no longer occurs at step 6.

I got a error "801812C0" and it said device couldnt be updated. i took the battery out and restarted it and it was updated wtf lol

Looking for some info on drivers!

hi guys, ive got a quick question for you.
When you put the device in to flashing mode (the black screen with the wee USB cable plugging in to the PC)
what driver is installed? when in that mode you should see a different USB device im guessing something like HD7 or perhaps its code name.
anyhow, if someone tell me that i would be very aprechiative, also if you can tell me which driver set its installed from, for instance, OEM11.inf or perhaps a zune driver set.
use device manager, it could be under portable devices or USB devices or windows phone devices, right click on it and go to properties, then details , im looking for the matching device ID, inf name, inf section, included infs
thanks for your time folks!

I don't have all the driver info, but I know it lists the device as "HTC Shubert."

well thats a start, cheers mate! amazing how 60 odd folk looked at this an didnt want to help, your an example to them all!
thanks again
Perhaps i can find the rest of the info trawling through google using that as a start, but if anyone can provide the INF details and device ID it would make my life that much easier!

was that definitely the name for the device as listed in device manager when the device was in update mode? Im finding info for that as the overall device name but not the friendly name, the friendly name is HD7 which is what would be listed in device manager and is listed when the device is connected to the computer in normal mode.
Basically what im looking in to is what exactly is happening when the HD2 is updated, it obviously doesnt work, im looking to find out exactly why that is.
when the HD2 is made to look like an HD7 it works fine and is listed as an HD7 in device manager, but the moment it goes in to update mode it changes back to a LEO device
Obviously this might not be the whole reason it doesnt work but if i can find out what driver is installed for the update mode with the HD7 i can fiddle with the device IDs in the driver inf file and force that to be used instead of the leo drivers. Now that wont work by its self i dont think but its one less thing that might be behind it not updating.
if that doesnt work than the next step is to compare the registery for both devices, but one thing at a time, and the driver issue is possibly the easiest to fix.

Bit weird here !
Hi
I've been having problems with the 801812c error.
After reading about updating the drivers using device manager, and doing so, (my device was listed as HD7) i found nothing changed and I still couldn't update, so I deleted the drivers, and then re downloaded them.
Suddenly I had loads more drivers, and my device is now listed as Windows Phone 7.
Still won't update though !
Sorry, just my tuppence worth.
Garrickus

sorry, say that again, your HD2 which is normally listed as HD7 or whatever you called it in zune, which in flashing mode is listed as a LEO?
so you updated the LEO driver and got it to use a HD7 driver?
so now in flashing mode its listed in device manager as a HD7 and it doesnt update still?
so putting all that aside you uninstalled the HD7 driver? then when you installed it again windows installed it as a windows phone?
again, this is all in the updating mode? in normal operations you will see a windows phone device and the HD7 device.
or are you using a native HD7? and i got that all wrong?
if you do have an HD7, put it in to flashing mode without the cable attached, turn off the device, then hold down the power button and the camera button, when the device turns on let go of the power button and keep holding the camera button, that should put it in to flash mode.
then in device manager check out what device is listed when you connect it to a USB cable, if you plug it in after you load device manager you iwll see which one pops up. then if you wouldnt mind going to properties and look for the info i asked above?
if you do have a HD7 and are having issues updating try this out
Windows phone support tool
and
ChevronWP7.Updater
install the first one which gives you a guide to updating and the second one does all the updating out of zune by its self.,
comes in two flavours, 32bit and 64,

My phone is updateing now, Here ya go!

Apparently I'm a noob and can't post img links yet, so you can go look yourself, just add the http header to each of the above to make them into links.

cheers, so thats using the zune drive pack, now if anyone has the device ID from the details tab?
i think im running in to a rock on this, bloody LEO keeps getting installed no matter what i do, im starting to think that the update mode must have its own registery or at least a protected section thats identifying it, because no matter what i do i cant keep LEO away, which is intresting because its not apart of the zune driver, its a windows mobile driver.... so where it keeps coming from i dont know

When i put my device into bootloader mode and connect it to the pc, Qualcomm Technologies MSM Windows driver was the one that got downloaded. Also, what OS are you running? you need to download windows mobile device center if you're on vista.Windows 7 should install that driver by default. Anyways, my hardware id listed when connected to zune is :
USB\VID_045E&PID_04EC&REV_0000&MI_00
USB\VID_045E&PID_04EC&MI_00
Also, if you're on xp, get the driver from here http://forum.xda-developers.com/showthread.php?t=408105 , its in the 10th post..

cheers for that, i shall check that out tonight, i had a small amount of progress last night, i have been able to perminantely change the driver installed to a windows phone driver, although its still called LEO for some odd reason, but anyway, so instead of a invaid registry error i now get a timed out error.
So im assuming the driver ive chosen wasnt correct, with out a hardware ID of a HD7 in update mode it gets quite difficult, however ill have a look through that driver you poster a link too, im on win 7 but even if i can locate the ID from that file i may be able to find a working complete driver set i can use.

my main problem is "Device handshake failed"

Hi folks
this is the first time for me with WP 7 i am with the Android since the G1 lol.
i got an a focus s from a friend and i said to my self , why you don't try it? its locked to at&t, so the first thing i have to do is unlocking it.
at that point the problems started!!, i checked the unlocking cost via code, the average is 30$ which is expensive for 80$ phone!!, so i choose to unlock it via fastgsm and unlocking via USB cable.
i followed the instructions and everything seems to be OK till the last step when the phone reboots to the download mode, the program shows "FAILED" i had contacted teh customer support for fastgsm and they tried to help me, with o hope, thereafter i didscovered that there is somethign wrong with the connection of teh phone to the PC.
i start to read and read and read again "noting that i am expert in android things" and finally i decieded to use the CAb sender and/or the "sharp7eighter' to update then SIM unlock.
both programs with the same error "Device handshake failed" noting that the phone is connected and shows i937 in my compute but it never ever recognized by Zune, always says "no device connected"
sorry for my bad English, but i am very sure there is something i can do to :
1-go back to stock
2-update my phone
just to connected the fastgsm program to be able to SIM unlock it at acceptabl;e price 15$.
please and thanks

Fastgsm stopped working with the focus s when the newer firmware got updated, I think it was version LE2, I know I had to pay for more expensive unlock although in theory we can achieve unlock without paying anything with gsmtools etc, but this is risky as I don't really know how, it would require some experimental work!
As for connection issues
On keypad of your phone type ##634# and click "Call" button to show Diagnosis screen.
Type *#7284# onto Diagnosis screen, select "Modem, USB Diag." For fastgsm, and "zune" for...well, zune and confirm selection
Restart and let me know how zune sync now works

so, the safest way is pay the 30$, correct? noting that the firmware is in the attached pic

OK, there are a bunch of things we are going to try
Firstly are you in a position to hard reset your device from the boot loader?
If so do it, If not turn it off instead
turn your PC off
Plug USB cable in to a different port on the back of your PC, do not use a hub, it has been known that some hubs can affect sync
Turn both pc and phone on, assuming you have used a different USB port windows will install new drivers
Load zune and try again
Sent from my arc 10HD using xda app-developers app

i didn't use the phone yet, so i have no data to lose.
for the hardrest i did it many times, from setting , about, reset your phone then turn it off, press the three buttons together (power+camera+vol down) and format.
i don't know what you mean by headrest via bootloader.
and i changed the USB port and used 3 different types of USB cables, with no hope
and the strange thing is, when i plug the phone, the zune starts automatically and shows no device connected !!!
i am very sure that the previous user for the phone manipulate wit the software, so all i am trying to do is revert to stock, and i have another question regarding the download mode, when i was using the USB method from fastgsm to SIM unlock (screenshot attached), it shows that the PC detect the phone and read all information, but when it restarts to the download mode, it "FAIL".

I think its connected as a MTP device, that probably explains it..
OK,
Im going to hazard a guess with drivers being the problem
with the device connected I want you to do in to device manager and uninstall the driver for it, make sure you click delete driver as well.
then Disconnect the device before it can start installing it again
then go to http://www.nirsoft.net/utils/usb_devices_view.html and download the program at the bottom, make sure you choose correctly between x86/x64
this little program will allow you to view and delete all USB devices connected past and present. basically select the device, right click and uninstall it, you will need to run the program as admin
Have a field day and delete anything and everything that might be related to the phone, if you whack something that isn't related all you will have to do is reconnect it and it will install the drivers again so there isn't much to worry about.
try that and see if that removes what I think is a driver conflict. mind it might not be obvious what is and isn't related so best err on the side of caution and keep only those that definitely are not it!
Note it might be Samsung, or i937 or Windows phone or WP7 or more annoyingly USB composite device of which you will have many, just mind one of these will be a keyboard and mouse, if it stops just unplug and plug back in, windows will take care of the rest
