My blackberry Storm 9520 had a screen freeze problem. I have to take out the battery and put back in and then its ok again. What can I do?

Hello, for network unlock, you can use the following solution: http://www.fastgsm.com/en/blackberry/bb/blackberry-storm-9530/unlock-code/msl-password

Do a 'Factory Reset'

You can try unlock your blackberry using blackberry storm 2 9520 network unlock code for your network.Example if your original network using t-mobile, then you need t-mobile blackberry unlock code to unlock your blackberry.

Yes, there is a solution and I hope this also works for you. My 9550 would freeze and I couldn't answer a call, or it will just freeze on it's own at least once or twice a day. I also had to remove the battery then replace it and it will be fine again. After emailing the store where I bought the phone. One of the solutions was to wipe the memory as stated here. (To try to "wipe handheld":
1. In the device Options, click Security.
If you are using BlackBerry Device Software 4.1, click Security Options > General Security.
2. Click the trackwheel and select Wipe Handheld.
3. Click Continue.
4. Type blackberry and All the data on the BlackBerry device is erased.)
Then restart the phone and it should work.
Better yet. If you have the BlackBerry Desktop Software Application on your computer. If you don't go here https://swdownloads.blackberry.com/Downloads/contactFormPreload.do?code=A8BAA56554F96369AB93E4F3BB068C22&dl=A2C0D61EB187AB3AFD247A852FAD3647 It's a 114mb file. Connect your BB with your data usb cable. Then back up the phone and do a software update (Which is what I did). The software will back up your data, then wipe your BB clean. Then it reinstalls the software. The process takes between 30 minutes to one hour to complete. You should be ok after the update. My BB 9550 works fine now since the update four days ago. No more issues.

Have you tried pulling out the battery and then putting it back in?

No one can give you free unlock code. because each blackberry have different unlock code. As far as i know unlocking by codes is the simple and safe way.You will need the unique MEP Code for your Blackberry storm 9520 and to get it you can use a website with service for Blackberry unlocking .so you can use a website to Unlock your Blackberry storm 9520 online instantly - OR local mobile shop .they are mostly using cables to unlock it and the price is higher then on unlocking websites but the result is the same: SIM free Blackberry.

To open the battery cover, you have to slide up the release bottons located at both lower sides, if this doesn't work, maybe the lock system is damaged, and the better choice could be to take you phone to an authorized Blackberry service center.

you can update with blackberry desk top manager it will find upto date software for your phone and should cure your problem but you need to back your phone up and your pc needs to be connected to the net

Check wheather its under warranty period.Mean while call you are operator (customer care) and they will let you knoew the nearest service centre.

have you removed the battery and put it back in.
his will reboot the software.
also make sure your battery is up to par, the battery in a blackberry when they get used for a while need to be changed, your phone is very graphic intensive and needs a very good battery to run without problems. replace the battery and see what happens.
