[Windows Phone 7 General] jashd7:
Hi everyone,

I'm posting a method today which i use to backup my XAP files and favorites. I hope that they will help others too and I'm posting some other tips too which i gathered around from the web and XDA. I will be constantly updating this post.

Most of the tips I've provided here are only for Fully Unlocked Phones

Backup .XAP files downloaded from Zune Marketplace

Access your phone's files using any File manager FileBrowser by ego zheng, Unique File Manager by Mohsen Unique Or TouchXplorer by julien Schapman.

Both FileBrowser and Unique file manager can open XAP files but TouchXplorer will throw an exception.

Open FileBrowser and Goto /My documents/Zune/PimentoCache/Lib/

There should be numerically named folders containing cached XAP files but with .ZMZ extension which will look like this

app0b792c7c-14dc-df11-a844.zmz Copy those files to another folder and rename the extension ZMZ to XAP. You should keep in mind that PimentoCache folder gets cleared after every few days. So you have to copy those files as soon as you've downloaded from the marketplace.

You MUST have XAPdeployer by Ultrashot installed for the following trick to work.

If you want to open ZMZ files in the FileBrowser to see which ones you are copying or renaming. Launch Registry Editor by Julien Schapman open HKEY_CLASSES_ROOT create a new key .ZMZ open .ZMZ and create a new String value "Default" enter "xapdeployerfile" in the value and tap OK. Now you can open ZMZ files in the file browser.

Backup XAP files downloaded with Bazaar App

Using Phone's file manager Or Windows Explorer on computer Goto

Application\Data\9daf0fc-a0ee-4cfc-905a-cc812d678a35\Data\IsolatedStorage

all homebrew XAPs downloaded from Bazaar will be in this folder.

Backup XAP files downloaded with wPhoManager

If you download files with wPhoManager from W.I.N.C.O marketplace all the XAPs downloaded will be in

Applications\Data\8A011F29-D5A3-4942-B865-71198AAB94AE\Data\IsolatedStorage

Screen Goes Blank during Incoming/Outgoing calls

I had this problem sometime ago when my HD7 fell real hard and started giving these problems. So I searched the web and found this solution from some website. If you are having problems (Blank screen and inaccessible phone) while incoming/outgoing calls it has to do with the proximity sensor. It goes out of alignment and that results in the black screen during the call. While the call is active, since the screen is essentially turned off by the proximity sensor, I can’t use the keypad or even hang up the call!

The fix is to press down hard on the area where the proximity sensor is. It’s located at the top of the screen – pretty much where the HTC logo is. Just press hard on that area and that should move the sensor back into place.

Backup Internet explorer's Favorites

Browse to /Windows/Favourites and copy all the content to a folder of your choice. Put them back in after you've reset your phone or installed a new firmware. You can also use IE fav Backup by Sh4d0w86 that's also a pretty good app for doing this task.

Saved Office mobile files OR copy Documents from computer to phone

All your Word, Excel, Powerpoint files you saved on your phone are stored in My documents. If you have files in your computer and you want them on your phone. Just copy all those to My documents and they will be in your files list.

Record incoming/outgoing calls complete with environmental effects ;)

This trick does not even need any sort of unlock. Call any number on speaker and press the camera button Switch to Video Recording mode and tap Record. Your call will be recorded in a video use VirtualDub(or any other audio extraction software) to extract the audio and Audacity to reduce environmental effects if there are any.

ZIP files

By default downloaded ZIP file's content (Which can open by default in Windows Phone 7)is in Applications/Volatile/ZipView/(This folder gets deleted when you close the ZIP file, So you have to keep the ZIP file open until you've copied). but the limitation is that you have to open each file individually. But if you want to download the complete file without any content limitation. Do the following method :-

»Open your file manager on your phone OR windows explorer on PC.

»Goto \Windows\Profiles\Guest\Temporary Internet Files\

»There should be folders with names like 9FADAF33, Q110E4PZ, U0GWIYEF and U2QKY63D(exact names can differ)

»Your downloaded ZIP file will be in one of these four folders.

»Copy/Paste downloaded ZIP file to another location where you keep your files.

This method is helpful if you are downloading ZIP files which contains DLLs, EXE or any other format files which WP7 cannot open.

Download WinRar, CAB, 7Z files

Windows phone 7 does not recognize these file types so it will not download these files if you want to. With the following tip you can download these files to your phone.

»Start your phone's Registry Editor and tap HKEY_CLASSES_ROOT

»Create three new keys .Rar, .cab, .7z

»Open each key and create String "Default" with "Zipfile" as a value

»Now you can download Winrar, 7Zip, and CAB files in Internet Explorer.
