Hello there,

my "new" Venue Pro arrived yesterday and i just started to test it.
It had a very old firmware, not even mango ... so i startet updates by zune.

After the third update (for wlan problems, i think it was the "latest" wp7 update) i get an error .... so i restartet the phone an tried again, no success.
I read a lot, not even the microsot update tool could help. So i startet the recover in zune over settings, updates.

The update startet and now i always get an error by 61%. I read a lot again, i even tried to backup it from another comuter (copied image %appdata%\Microsoft\Microsoft Phone Update) but the same problem.

So, my "new" phone doesent start any more ... it just loads to the bootloader ...

I tried to get any offiziel firmware to flash the device to "standard" but i seams hat MS dont want this.

I knew a little bit about flashing WM6 devices (HSPL & custom fw) but with WP7 devices i dont really understand what to do in this situation.

I hope you can help me! Can i download the dell firmeware someware to recover the phone? maybe someone have a "personal recover firmware" for me?

If your device can load into download mode (that you called "bootloader") it can be restored to 7004 T-mobile branded version and later update to 7720 via Zune. This is only one available firmware on the public.

So, i downloaded VenuePro_flash_GLEOS2A_US_TMO_SIGNED_SWV0105_LP003 0_RV001_RETAIL.ffu and thought, everthing is getting fine.

But i had no idea how i can install this!

I´m reading hours and hours, tried to use UpdateWP.exe (crash on 2 computers, where NO MS Support tools are installed), Windows_Phone_7_Backupv1.9, MangoB2-ZuneClient, Zune 4.7 .... no success.

Could sombody please tell me, how i can install this on Windows 7 x64? I dont know what to do ...

As i said before, there is no (more) Microsoft Update Software on my computer and on the second there never was it.

Mybe i could handle it with the "MangoB2 Updater" .... but i cant download this anywhere.

I really have no luck :(

Do not panic yet. You have different versionsof zune or updatewp /missing files
Install Net framework 3.5, 4;
Install Zune(take it from;
Install wp7 updatetool from zip attached here here with proper x64 file.
Follow those steps after connecting device in download mode:
Extract command prompt to C:\program files\zune\
go to directory to “C:\program files\zune\ and run Command prompt. Type in : “UpdateWp /list” and your phone should show up there.
If your phone is listed (it should be) and your download is done and extracted, copy the VenuePro_flash_GLEOS2A_US_TMO_SIGNED_SWV0105_LP003 0_RV001_RETAIL.ffu file over to the” C:\program files\zune\” directory.
Type in: “updatewp /ffu VenuePro_flash_GLEOS2A_US_TMO_SIGNED_SWV0105_LP003 0_RV001_RETAIL.ffu” enter, update should start.

Great, now i can start my dell venue pro again and even updating is functional.

But why can´t i change the display language? I tought i´m able to change the display language in this roms? In all WP7 phones (in germany) i could change the language at the first start (and after a reset).


On this site i found language packs, but that is a little bit ... argh?!
