Windows phone 7.8 to 7.5 - Windows Phone 7 General

Is it possible to downgrade my HTC MOZART now updated to 7.8 again to 7.5 because 7.8 is really ugly on my phone, I reinstalled my PC so I do not have back up on my Zune. Thanks

I believe you just need to downgrade/switch to SPL and install 7.5 as usually.

I actually don't know how to do that

I think you can download and install Original ROM with older version. It works on my HTC Titan, i think it should also work on Mozart.

yes I thought of that too, but will you please tell me what version should I install on my phone, here is my info
Firmware revision number: 2250.21.51303.401
Hardware revision number: 0004
Radio software version: 5.71.09.02a_22.51.50.21U
Radio hardware version: A.102.0.D4
Bootloader version: 5.13.2250.3(135167)
Chip SOC version: 2.2.5.0

why every time when I give my info everybody stops talking and nobody is tellinme what to install ... ? :'(

I know if you installed the update through zune you can revert back to 7.5
I did this through zune to my mozart as it slowed down the phone launching apps off the homescreen... 7.8 slowed down my HD7 aswell...
In zune, go to where you update/check for updates and choose to revert back to previous...

I reinstalled my PC and don't have the backup(revert) in zune

Problem updating Vogue

Hi everyone,
I have an HTC Vogue (branded here (NZ) as an Okta Touch)
CE OS 5.2.19208
ROM version: 3.00.718.4 WWE
ROM date: 02/04/09
Radio version: 3.41.00
I am trying to update to WM6.5 but every time I run the application it says:
"ERROR 262: UPDATE ERROR"
And then it goes through a recovery process. It doesn't affect the device at all but I'd really like to know what's going on and why I am unable to update.
Thanks!
P.S. I haven't unlocked it, not sure whether I need to. Also not sure how to.

hello trying to unlock my diamond

Hi Guys
I am trying to unlock my diamond. I have purchased it from Bell canada
and so far this is all I know about it. It is a DIAM500 whatever that means.
This is what it says in the about page
Windows Mobile 6.1
CE OS 5.2.19972 (Build 19972.1.2.7)
2008 Microsoft Corp.
ROM Version 1.13.666.7
Rom Date 10/02/08
Radio Version 1.04.02v
Hardware version 0080
PRL Version 31402
PRI version 1.42_007
So anyway I am not sure but this is probably really outdated stuff. I am not even sure if this is a CDMA device and how can i figure that out? I downloaded a diamond unlocker but it says I should install Hard spl 1.40 first.
So with my current config is it safe to do so? Any help is much appreciated.
p.s. I tryed to update the ROM trough the official HTC website but it wont let me update since it doesnt recognise my serial
number.
Look at this and ask questions in there:

How do you tell wich WM version is running?

Hiya, I have a HTC Cruise and wnat to know which version of WM is running. I ask this as I sent HTC an email about their upgrade to 6.1 and the info they sent back was a ROM update with the same ROM version.
My phone device info is:
ROM version of 1.26.710.1 WWE
ROM Date of 12/17/07
Radio Version of 1.58.21.23
Protocol Version of 25.65.30.04H
To me the above numbers dont mean a heck of a lot but I hope they do to someone else..
The "About" screen indicates it is "Windows Mobile 6 Professional" (if it is 6.1, should it say "6.1"?)
Cheers
IJ
Start, Settings, About for the WM version.

If it indicates that, then it's the WM version, some devices don't have the most recent Windows Mobile update from HTC.
If you wan't to try, usually you must use cooked ROM's from XDA Dev's.

Zune 4.8 Official Client Testing for current Mango B2 - RTM users

Although I'm sure this may not be an issue, but I think we need to have some testing on upgrading to the Zune 4.8 official client to see if there are any issues with users on the B2 and RTM... or even any new updates introduced due to the arrival of the new client.
On B2 and haven't had any issues with the new Zune software yet.
I also see my most recent restore point available in the new Zune software, but I haven't tried it (and I probably won't until Mango final), so I don't know if it will restore properly as of yet.

Hmm.. I wonder about backups/restoring.. if that's changed any. Thanks for giving a B2 input. Now we need an RTM tester.
I am on RTM and Zune 4.8 is working without problems.
Phone is still unlocked.
P.S. No need to download Zune 4.8 from web, just update from beta to final with check for updates function.
I'm on RTM too and I haven't any problem with this software and phone is unlocked too. I don't tried restore from backup but when I try, I write about this.
Diez this official zune release jeans that mango launch is almost here?
I think you mean here is where to download the official version of the Zune 4.8? If so try this: http://www.microsoft.com/download/en/details.aspx?id=27163 for your language you must change from context menu "Change language"
B2 issue
Just updated to Zune 4.8 via update in zune. As of now, phone no longer connects to Zune. Running B2 on an unlocked Roger's Samsung Focus on Telus
Just updated
Hi all
I have just updated to the "Final" version of the Zune software (4.8.2345.0) which was delivered via an over the web update from the "RTM" version.
My phone is WP 7.10.7720.68 and connects without problem to the new Zune.
Thank you Microsoft!
Cheers

Thanks for the hint on manual Zune update! The software did not prompt me for updates, so I tried the manual way as described. In addition to that, Zune installed new drivers for my HD7. The rest works just fine.
I have an HD7 with Mango RTM, works flawlessly.

a) For the love of God people, please use question marks!
b) He said he's on 7.10.7720.68, that's the RTM not the official dev beta.

Cannot update to ISV 7712
Hi!
Today I wanted to go from 7390 (Custom ansar) to 7720 but update to ISV 7712 beta failed with this version of Zune.
If I go from 4.7 it says that before performing any update (both 7390->7403 and 7403-> 7712) I must update Zune to 7.8 which fails to update to 7712 (tried 3 times).
So I'm stuck at 7403/7390.
Can anyone confirm this or is there any known workaround?
I guess I should wait for the official 7720 update through Zune?
Regards,
Cina.
Which version of Zune are you running?
When I was going from NoDo to the two betas, it made me upgrade to 4.8.2345.0. Once I got to the step to go to 7720, I ran into the same issue. I uninstalled Zune and reinstalled 4.8.2134.0. After that, I had no issues installing 7720 (RTM).

I'm on official Zune 4.8 and Mango 7720.68, no issues with sync. Could it be that you are handling the phone with another program (perhaps the USB enabler or something can interfere)? Check Zune is set to open when the device is plugged in, and be running the latest Zune.
