How can I backup my text messages to iPhone in PDF format?

If you back up locally on an Apple machine, you can find the file under Library > Application Support > MobileSync > Backup. There should be multiple folders there, each with a different backup image of your phone. Each of the folders should have a file named " 3d0d7e5fb2ce288813306e4d4636395e047a3d28.mddata." Those are your texts, in SQLite database form.

On a Windows machine, you can find that file in C:\Users\[USERNAME]\AppData\Roaming.

Unfortunately, you can't open up that file in a text editor - you'll either need a SQLite editor or a special third-party tool. But at the very least, if you copy that file and keep it somewhere safe, you've got an archive of your text messages. Here's an online service where you can upload that file and download the content and metadata in either PDF or CSV form. Total Recall How to Back Up All the Text Messages on Your iPhone

Speed Up Firefox loading times by defrag of the places.sqlite

Having database store your browsing data has one drawback, you have to optimize the database from time to time to get rid of old, deleted data, re-index the columns etc.Otherwise you keep all the junk data mixed in with your real data.

Over a period of time your places.sqlite database will fill with data of your browsing history this will cause the loading of Firefox to become sluggish even on fast PC's it almost appears to freeze and make you wanna go back to IE8 or to Chrome it don't use this Tip and stay with Mozilla.


There are several solutions the easiest is to rename the places.sqlite file to places.sqlite.bak and if you need to open this file and save any of your history links you can use Nirsoft's excellent MozillaHistoryView you will have to select the Application Data folder manually in order to edit this file this one has almost 8,000 entries and is over 3MB in size.

If you want to do this automatically there is an XPI add-on called Vaccum Places that you can set to do this for you I prefer removing the file every month of so and using the viewer to save any websites that you might need


To activate the sqlite defragmentation goto the tools and click the last entry Vacuum places.sqlite and you will receive confirmation in the lower right hand corner of the desktop you will see a marked improvement in the cold start of firefox, you can set this to automatically do this after a specified number of starts I find 30 to be a good number.

Remember this will not remove entries but place them in order to make firefox faster so if you use the Nirsoft viewer you will still have the same number of entries just in a better order.


You can also set the history to only keep a few days history, 90 days is the default which is too long you can get away with 20 or so quite easily use the settings in the Firefox browser to do this.


You will notice a huge speed up on the loading of your Firefox from several minutes to a few seconds using a combination of the Vacuum XPI and reduced browsing history settings.

If you want to compress this sqlite database and remove a possible bug caused by Google toolbar bloating the dB then use this free software you will have to unzip the archive into you own profiles folder and then browse for the places.sqlite file create a backup prior to doing this


You will need to find the default Firefox profile and make a backup copy of the places.sqlite file access this using the following command from the run prompt


Happy Faster Firefox-ing you can reduce your database down by about 10% removing all the Google toolbar entries using this compression from RECENTX and speed up your Firefox loading time I used this then uninstalled the google toolbar didn't use it anyhow.

There are also 4 more XPI add-ons that will do this however I prefer the Vacuum Improved one


The SQLite Optimiser XPI as well as the Vacuum function has the added indexing function which also speeds up the loading times the result should look like this.

Acer eRecovery management Restore system to factor default but I don't know the password

Locate and Unhide Hidden Rescue Partition
  • 1 Access the Diskpart command prompt. Acer stores custom eRecovery passwords on your computer in PQService, a hidden rescue partition. Locating this partition requires accessing the Diskpart utility from the command prompt. Diskpart allows you to run a scan on your hard drive and bring up hidden partitions. To access Diskpart, go to Start and type "cmd" in the search bar to bring up the black command prompt box, and then type "diskpart" at the prompt to switch to a Diskpart prompt. Depending on your computer, a new command prompt may open with the Diskpart prompt.
  • 2 Scan your computer configuration. At the Diskpart prompt, type "rescan" to run a system configuration check. When the scan finishes, you will receive a message informing you the scan is complete. At the command prompt, type "list disks" to bring up available disks and then type "select disk 0."
  • 3 Locate the hidden partition. At the command prompt, type "list partition" to view a list of partitions on your disk. Locate the partition with no name and a size of approximately 10GB. At the command prompt, type "select partition (number)."
  • 4 Determine the partition type and unhide the partition. The hidden PQService partition will be either a type 27 or a type 12 partition. If the partition is type 27, unhide it by typing "set id=07 override," and if a type 12, then unhide it by typing "set id=0B" at the command prompt.
  • 5 View the PQService partition. Return to the disk containing PQService by typing "select disk 0" at the command prompt, and then type "list volume" to view the contents of the disk. PQService will be visible in the list, preceded by a number. Type "select volume (number)" and then assign PQService a new drive letter so you will be able to open and view it from your computer interface window. At the command prompt, type "assign letter=f."
Reset eRecovery Password
  • 1 Open PQService. Navigate to the drive containing PQService. Find the file "aimdrs.dat." Right-click on the file and select "Open with" and then "Textpad," "Notepad" or another text editor you prefer.
  • 2 Open the file and find the password. Open the file with your text editor and locate the eRecovery password. Look for a line that reads, "Password=password name," "Hint=the password hint." Write down the password and close the file.
  • 3 Open eRecovery using the recovered password and follow the instructions to create a new password.

'Table does not exist' error in MySQL, although it really exists

it usually means that no table exists in the default database with the given name. In some cases, it may be that the table does exist but that you are referring to it incorrectly. Maybe your database and table names are case sensitive if they are located on a file system that has case-sensitive file names. Or perhapsall references to a given table within a query must use the same lettercase.
Use SHOW TABLES to check which tables are in the default database.
Well, if you are sure that table is exist and you write its name exactly such it should be, then I suppose something wrong with the database, it can be seriously corrupt. And in this case you need a professional help. This tool must help at any rate - Recovery Toolbox for MySQL

I have an ipod touch. Its 8 GB but I dont know exactly what kind it is. Ive tried to restore it with itunes and its not working. it says its disabled for 23,056,662 minutes. It was given to me as it is so...

This might work, sometimes it does.
1) press an hold menu an center button on click wheel until it turns off an has worked on some machines.
2) connect to your computer, connect to your device ipod, look for a file named "locked". Open this file with your text editor, called Notepad". And your pass code should be there. Then rename it, close editor, close down from computer an try to work it then.
Does not always work but is worth a try.

I use firefox and I'm haveing trouble opening my yahoo mail

this can be caused by corrupted cookies.
"Clear the Cache":
  • Firefox > Preferences > Advanced > Network > Offline Storage (Cache): "Clear Now"
"Remove Cookies" from sites causing problems:
  • Firefox > Preferences > Privacy > Cookies: "Show Cookies"
If clearing the cookies doesn't help then it is possible that the filecookies.sqlite that stores the cookies is corrupted. Rename (or delete)cookies.sqlite (cookies.sqlite.old) and delete other present cookie files like cookies.sqlite-journal in the Firefox Profile Folder in case the file cookies.sqlite got corrupted.

Hope that doesn't sound too confusing!!! Before you do that, try going though Internet Explorer and see if you can log on that way. That way you will know if its just firefox or another problem, if so than do what I wrote above!! Hope this helps you!! (*_*)

I cant change desktop backgroung i dont know why :@ at samsung n145 pc.. its not possible. i click on desktop but there dont show me " properties" and anywhere else in pc i cant change too !

What OS are you running? The N145 comes with Windows 7 Starter. One of the limitations of Windows Starter edition is that the background is fixed. You will need to upgrade ($$) to a different version (Home Premium, Pro or Ultimate) to unlock the desktop background.

On higher editions of Windows 7, right click on the desktop and choose Personalize to change the background. (Alternative route > Start > Control Panel > Appearance and Personalization > Personalization )

I wish that I had better news for you.

(your other option is to install a different OS (non-MS).)

My Animal Crossing Wild World game is in good condition and everything works fine except when I try to use it with either code breaker, or action replay it does not work. These things seem like they dont...

Ive got an action replay and the same thing happens. Its just because the action replay or code breaker isnt the right type for the game. This plug thing should have come with it which you plug into your computer and then delete all the waste in it which is also a cause for it not to work but for now i wouldnt use it if i were you.
