Welcome to Fixya

Sounds like the phone's firmware is already corrupted. Try to troubleshoot it first. Remove then memory card and sim. Remove battery for 5 mins. Press and hold the power button for 15 secs without the battery. Put everything back to the phone then turn it ON. Try to reset the phone back to he factory state if same thing will happen. Press and hold the Volume Down, Call and the Power buttons, until the LED (at the side of the camera) flashes. Release the buttons. That LED should flash in green/red/blue. After doing the procedure the device should be cleared from errors.

Failing to operate some function like camera,gaming,internet browsing,message sending etc. might due to a memory full problem. if the phone memory free space is too low, it will not allowed any operation as what above stated.

To avoid this problem, be sure all multi-media files are stored on memory card or mass memory storage. delete unused file for saving memory space.If still the same way around, you need to format or reset your phone by going to settings then master reset.be sure to back up all important files first before doing this method cause everything will be erased. It will ask for a confirmation code then enter 0000, after entering the code it will automatically restart the phone .Your phone is now sets on original default settings.


Hoping this method helps...

go to settings and restore it to default (reset)

default code is 0000

You can go to "Settings",
Then "reset settings".
The Code for the reset should be 0000.
Though I personally haven't tried it, I'm told that you should NOT lose any data, just custom menus.
Best Wishes and Good Luck!

Hi Prem,

If your phone is constantly restarting one thing you should do is to take out the battery from the phone and leave it out for about a minute or so then put it back in. If this doesn't work, if your phone has a SIM card, (the card your cell phone provider usually gives you) then take that out along with the battery and put it back in after 5 minutes. But first you should try taking out the battery.

Hello,

Try to charge the phone and power it on, take note, if the chargers metallic point makes contact with the metallic part of the charging port, then the phone will not come on unless you remove the battery and insert it back in. Ensure the battery's metallic point is making proper contact with the phones battery terminals.

First of all you need to run a quick check on the phone before we can conclude that the phone is bad and need to be repaired. Remove the battery and insert it back in then try to turn it on. If it does come on, then that solves the problem, if it does not, then you need to carry out some further test to find out what the problem is.

First check if the battery is properly charged. To do that, insert the battery into another phone and turn it on to see if the battery will power up the phone. If it does not power up the phone, then you know that the battery is either weak or bad, then you charge it using a universal charger or a normal charger to see if it will hold a charge, if it does power up the phone, then it means the problem is not from the battery but another component in the phone.

Try out a well charged battery inside the phone and turn it on, if it comes on then the phone is intact and the solution is for you to replace your battery. If it does not come on, then there seem to be a problem with the phone.

If these are not the cause of the problem, then you will have to take it back to the dealer that supplied it to you since you might still be under the warranty period, for them to either repair the phone or replace the phone for you. Be sure to have your warranty card with you, if not the dealer will not be able to offer any form of assistance to you.

The phone might have fallen or hit a hard object and that might lead to damages inside the unit of the phone.

Hope this helps!
