For all of you trying to instal WP7 and getting stuck at the dreaded chevron unlocker "Uh-OH" that will not let you pass, look no further. There are a lots of ifs and buts but no definite answer to it. Below method worked 100%.
I tried it multiple times. I in no way encourage you to use WP7 and unlocking procedures but heres simply what you do if you want to do
Instal Zune
Connect WP7-HD2
Click on the sync relationship below the picture of your LEO70
key in any name...i used HD7
Once connected, create a zune id...You can use your windows live id though
Goto settings ---date and time and uncheck automatic date VERY IMPORTANT
sync your phone...Check if port 443 is free that means no SKYPE or anything. Instal registry key in windows
Put chevron installer on root of C
Stop any antivirus & anti spyware IMPORTANT
Run chevron with administrative controls
Make sure before running chevron that Wp7 is Screen on and not keypad locked. Make sure the white screen on zune is there clearly showing your phone model and name that you made.
I do NOT have the developers kit or tools installed.
I am on windows 7 64 bit
So this kills all speculations.
Hope you guys can get it to work.
I needed to disable my web proxy (Privoxy, in my case) for ChevronWP7 to work.
Note that you may need to reboot for proxy changes to be picked up by the Zune *service* (not the app).
also i had to close the SKYPE, however it sounds
can u make a video ?
i was traying last 2 day to sync my hd2 (w7) to my pc (windows 7) with zune software but nothing works
I have got WinXP SP3 and it's not working on that ever after using your method.
DID you disable the auto time settings?
did you add the registry key?
Mind restarting the phone and the PC?

Ok..some noob questions because every day i see new things here and to much info just confuse me... This guide will help me unlock (jailbreak) my phone without Activation from Microsoft?????
Or do i need to follow these instructions first following by the MS Activation:
http://forum.xda-developers.com/showthread.php?t=912218
Also...My only care is to sync Music and images on my WP7 HD2.. I don't need games and such! What do i need to do?? I am downloading zune right now...After that?????
There doesn't seem to be a cure-all for this issue.
I was able to get mine successfully unlocked yesterday almost by chance.
I had to keep going into Command Prompt (administrator mode), keying in c:/windows/system32/drivers/etc, and then executing "notepad hosts" and deleting the host file that the phone kept creating everytime I ran Chevron.
I also had my phone in airplane mode.
Today, I decided to blow up the phone with Task29 and reflash WP7 to see if it helped my battery performance. Much to my chagrin, I was unable to duplicate whatever worked for me yesterday.
I'm back on Android until this is fixed with a known, proven solution for multiple users.
i just install the windows phone drivres and it woks , i just unlock my hd2 but the market dosent work on the phone

how did you install the windows phone drivers because when I plug my phone on my computer ( windows Vista 32bit) it just say it just say installing that's it. Also i can't see the phone in Zune no matter what USB port i use or computer. Help would be greatly appreciated.
So to get this straight...to sync my images,music (ONLY!!!) I have to Activate my Phone with Microsoft??

OK start up your mobile. Is the date and time correct (Very important) if all ok then start zune. open up the chevron on c/drive and see if it will connect with ot the Ohno message.
You may have to do this a few times. try the other computer as well.
Some guy's can get the chevron to work, by puting the date a few months forward NOT back.
If you do manage to get the chevron unlocked, then dont lock it.
Make sure to swith off spyware detectors, and put your antivirus into stand by mode until you complete this tasks.

I had the same problem, but then I used the wp7 update cab sender and dev_unlock.cab which worked
http://forum.xda-developers.com/showpost.php?p=17306513&postcount=1
custom ROM is already unlocked (BTTF and HD2O) but people not read instructions... chevron is useless for this ROM's
Alright i've checkron chevrons website and the tokens ($9) aren't for sale right now, but thanks everyone.
how to
since it took some time for me to find out how to side load apps in WP7.5, I'll explain it to other noobs:
You need to install Zune, the .NET 4.0 Framework and Windows Phone SDK 7.1. Then install Phone7Market (you can find it here). It comes with the Phone7Market itself, from which you can download your .xap files and with the Phone7Deployer. Connect your HD2 via Zune, create a desktop shortcut for the Phone7Deployer, get your xap file you want to deploy (i.e. from the Phone7Market) and drag&drop it on your desktop shortcut. It won't harm to check the two boxes (remove drm and the other one). A few seconds later, you should find your app/game on your device.
btw, this is FREE, so you don't need to pay 9 bucks for chevron.

I'm sorry to hear that, but I can't help you with that since I don't have this error. The only two things that come to my mind: You need Windows Vista or 7 for the SDK and you should try a hard reset on your device (backup your data before of course).

Same error here.
Feb 2012: This guide is somewhat obsolete now, because of WindowsBreak project. A simpler unlock guide is in posted here and a complete unlock + Internet Sharing guide is here.
I did this guide as I didn't find a complete noob guide, up to date and with all links in one place.
Noob friendly unlock and update to Mango (keeping Chevron unlock) how-to
Prequisites and must read/understand before proceeding:
Zune 4.7 might be needed, I'm not sure 4.8 works. Uninstall 4.8 and install 4.7 if unsure (and don't update it).
Micro SD card: If you want to install a micro SD card, you have to do it before step 2 (recommended after flashing 7004 - step 1). Also recommended to format the card beforehand with FAT32 (32K or 64K clusters). Then hard reset the phone from Settings/About/"Reset your phone" or the 3 buttons combo (see Focus wiki). When a new micro SD card is added, the phone requests a hardware reset to recognize it and properly work.
Flashing: doesn't affect in any way phone's functioning as long as it's not interrupted in mid process or the phone doesn't have a hardware fault. Recommended to flash the phone on a laptop or a PC+UPS. You can backup your current firmware so you can restore if needed. Flashing, downgrading, upgrading firmware etc does not affect Network Unlock. Once your phone is unlocked to any network, it will remain so, regardless of flashing firmware.
Remember, if you hard reset (in Mango - or any WP7 OS version), you will lose Chevron unlock (ability to deploy XAPs) and to get it again you will have to re-do all the unlock process above.
You can use hard reset to revert to "factory" settings
Optional: To deploy XAPs, Windows Phone Developer Tools is no longer a requirement (about 3 GB). W.I.N.C.O.'s mini SDK WP7 is a smaller solution (4 mb instead of 3 GB - see point 3 below.)
0. (optional) Backup your current firmware, PC program and steps read here.
1. Flash AT&T or Rogers ROMs (7004) from this thread (note: 1st post links no longer valid, new links here)
Personally I recommend Rogers, as it's cleaner: doesn't have the AT&T apps & customization/logo etc. If you're unsure how to do ROM flashing, read my post here (I referenced AT&T "Cetus" ROM there, so replace "Cetus_ATT" with "Rogers").
1b. (optional) Add the micro SD card and do a hard reset (Settings/About, press "Reset your phone"). For compatibility, read this thread or the Focus wiki.
2. Unlock with Chevron, program, steps and video tutorial here
2b. Please note: the Chevron certificate has expired on 25 November 2011. To still be able to use it do this: mail the certificate to yourself. Open it on the mail in the phone, click on the certificate and when the "shield" appears, close it, don't install it. This just insures that the certificate has been downloaded to the phone, so you won't need internet connection to install it later. Now, disconnect the PC from internet, and set the date on PC prior to 25 Nov 2011. Then, set the same date on the phone and put the phone in Airplane mode. Then, install the Chevron certificate. After this, reconnect the PC to Internet and use Chevron to unlock.
3. To deploy (install) XAPs, download and install W.I.N.C.O.'s mini SDK WP7 and then wXapAssistant
3b. Optional/alternate method of 3): if you already installed Windows Phone SDK, you can use Phone7Market on PC from here to deploy XAPs. Once installed, in the folder you have "wp7-deploy.exe" which you can use to deploy/install XAPs, ie wp7-deploy.exe full_path_to_XAP\XAP.XAP, as in:
wp7-deploy.exe C:\WP7\New_SMS_Unlock.xap
4. Immediately after unlocking, install and run Samsung Tools from here, to prevent relock
Check all checkboxes and reset.
4b. (optional) In Dialer, dial ##634# , this should open Diagnosis v929 (just for checking)
5. Install WP7 Root Tools from here
6. Deploy New_SMS_Unlock.xap from here
7. Run WP7 Root Tools on the phone, and in Explorer tab, create a folder "provxml" in the root directory. Now go inside "Applications" subfolder, then inside "Install" subfolder and locate folder "D19A....". Inside, find the "unlock.xml" file. Tap and hold and press "Copy". Then navigate back to "provxml" folder you created, go inside and press "Paste", and see if you have the "unlock.xml" file in it.
Please note: you won't be able to see the "unlock" option in Diagnosis by typing *#9908# until Mango (Rogers) or NoDo/Mango (AT&T).
8. Connect the phone in Zune and update the phone all the way to Mango (7720/7740/later). Keep in mind that if you do this with Zune 4.7 you will have to update to Zune 4.8 now to be able to sync. That's ok.
9. In Mango, uninstall Diagnosis app (if you installed it).
10. Open Diagnosis again by typing ##634# in Dialer. When in Diagnosis type *#9908# . Select "unlock" (should be the last item) and press "Save". It should say "Loading GPRS..."and you can exit Diagnosis.
10.b (optional) If you want to be extra sure, you can re-do step 4 again for good measure.
Congratulations, you are now unlocked in Mango!
Important:
In case something happens and your phone gets re-locked, just run only step 10+10b and you will be unlocked again.
Optionally, you can do Interop unlock, read here. Alternatively, you can enable Internet Sharing+Interop unlock (2 in 1, in the file "DiagProvXMLv0.91_IS.xap") from here (run "DiagProvXMLv0.91_IS.xap", go to "iso store" tab, press and hold "Interop Unlock" then press and hold "Internet Sharing"). You will also need to deploy a fix for the 3G: "Samsung Repair 3G by Heathcliff74.xap" from here if you do Internet Sharing.
This has been tested to work on AT&T and Rogers Focus with hardware revision 1.3, might work in 1.4.
To check what hardware revision you have, either look under the battery or check my post/thread here.
Don't forget to press Thanks on the original tool/thread poster!
Thank you very much. I was looking for exactly such post/article. I have Zune 4.8 already installed. Can I go ahead with it?

Sure, please try. No worries, if it doesn't work, just uninstall it and install 4.7
I have reached till step 7. I have now copied "unlock.xml" to a new folder "provxml" in root folder.
Before proceeding further, I want to confirm one thing. I did *#9908# while still at 7004 in diagnostic app. I do not see unlock option. Is this normal? Is it only visible once I am at Mango?
If yes, then I can upgrade to Mango without any worry.

Yes, it's normal. Diagnosis doesn't support the unlock until Mango. Will add this info to the guide too. Thanks for testing!

Chevron is quite an iffy program, please make sure you respect the steps there exactly and also check the video tutorial. Also, best way to achieve that is to close all programs running and re-try unlocking. Skype for example interferes with the unlock process.

I also had a problem Saturday when I updated my SD from 16 GB to a 32 GB one. Initially Chevron didn't work, it worked after I connected the laptop to internet and restarted Zune. Also, make sure the date is prior to 25 November (try 1 Oct 2011, that worked for me) on both devices.

I have finished updating to Mango and I was able to unlock Focus. So I can confirm that all works even if Zune 4.8 is used for each step. Yahoo!!
I haven't done Interop-unlock yet, I will do it soon. But that also should work without any issues.
Edit: Does the limit remains unlimited for applications? And is there any additional step(s) required to keep it unlocked similar to the one which was done by running Samsung tools?
thank you for the thread EnderPsp...this is what i was looking for...
i think i dont need to do the 1st step as i am already on 7004 and just got the phone from ATT.
I installed zune 4.8, installed developer sdk from MS, installed the certificate in phone by changing the dates. Now when i connect the phone to pc, and run chevron in admin mode with the phone on home screen and zune running, it opens up, i check the 2 boxed and then it says problem communicating with the device - make sure you are connected via USB, etc etc...i guess this is a common problem but i am unable to find any solution...i tried many times but it shows the same error...
Your help highly appreciated..

Try this:
- install the Samsung drivers from here
- set the date to 1 Oct 2011 and disconnect the PC from internet
- set the same date on the phone and do a hard reset. Re-enter your live id and e-mail (to where you sent the Chevron certificate) and install the certificate, then set the phone to Airplane mode
- reboot and once windows loads don't open any program, and close the ones automatically started (YM, Skype etc)
- connect PC to internet, start Zune and try to unlock in Chevron
Let me know if that works for you. Keep in mind that on a 64 bit OS it might be harder to unlock.

Either of these
- this method
- the developer unlock for $99 or whatever it is these days
- Chevron labs token for $9, but that's not always working (depending on the phone and revision...)
You can always backup first and try this. Worst case scenario you'll revert back.

This guide allows you to unlock, IF you flash. If you are in Mango you can't unlock using this guide unless you do the flash downgrade, but the other 2 methods should work.
You backup from the tool specified in the link and you restore using Zune, as the backup is created to be accessed and used by Zune.
currently flashing 7004 rom from the given link...will post with updates..
im done...now on mango and able to deploy xap's....is there any limit for the number of xap's i can install ?

My phone is unlocked, but I am unable to install applications on my device, I'm running HD2O latest rom v1.26 fully unlocked?
Though I am connected to Zune and the phone is syncing, but the TOM XAP installer says:
'Please make sure your phone was unlocked'
'Please make sure you connected device to PC and Zune launched.'
Anyone with solution?
You must unlock your phone (your screen must be on,like you wanna do something with your phone,send sms,or do some other thing...),and then try to send xap
