Blackberry is not charging , i have tried different battery and mains charger which is working with the other blackberry which is in the house hold

when blackberry is on it just goes to the the BLACK SCREEN with the clock on it and then freezes

any help would be great , thanks

model is 8520

The most likely problem is a bad battery. Replace it with a new, OEM one, made for your device, not a cheap knock off.

Is the battery inserted properly? Are the contacts clean?

Have you let the battery run down past 20% more than a few times, on a regular basis?

battery is brand new so bad battery has been ruled out ,took the battery out again and after the reboot its going to the main screen now , but its still freezing , ruled out battery now as i can see its fully charged so the freezing of the phone is the issue now , same again any help would be great thanks

The freezing then is likely due to some application you have loaded, or recently loaded.

You can reboot the device in Safe Mode and remove the app or theme.

-- Remove and reinsert the BlackBerry smartphone battery.
-- When the red LED (Light-Emitting Diode) goes out, press and hold the Escape key until the loading screen appears then release the Escape key.
-- When the Smartphone boots up the Safe Mode disclaimer listed below appears, click OK to dismiss the disclaimer.

I have the blackberry 8520 and its started to freeze , then work again then freeze then work again , what are the fixes for a problem like this , have took of all apps running in the back ground , have tried safe mode i have tried taking the battery out for 5 mins and also 1 hr , the battery is fine as its been tested in another blackberry , any help would be good as my daughter is climbing up the wall as her blackberry looks knackered

Was it dropped or did it get wet or even damp?

nope , not that i am aware off

Wipe out the BB using JL_CMDER

Follow the steps here -> Latest OS: 8520 5.0.0.1728/5.0.0.1067 (All Languages) to reinstall the OS.

Check back after you do the wipe etc. let us know how you made out.

done it and its still the same , its working then freezing , i think it could be going to the phone grave yard

Just to be clear, "done it" means you wiped the device such that you saw the 507 error, and then you loaded the OS?

Did you test with just the stock OS before you restored apps and data?
