Hi Ronaldo

Try this..

• Open up the dialer and enter - *#06# to check your IMEI number, if you see "IMEI Null or 000000 ", you need to reconfigure the settings to fix the no signal or not registered on network problem on your Android phone.
• In the dialer, type- *#197328640# or *#*#197328640#*#*
• You will be prompted into the Command mode, provided On the screen, Select on Common, normally option 6
• Now Select (FTM) Option 1. FTM (Field Test Mode) is for debugging and testing, if the option is on, you will have to turn this OFF.
• As soon as you turn this off, your NULL or altered IMEI number will be restored
• (Important) Without leaving the Command screen, press the Menu key, the button that's found left of the Home button.
• Select Key input and enter option 2 which will turn your FTM OFF
• Wait for a minute. Remove your battery and SIM card for two minutes, place your battery in your phone back but not the SIM card. Turn on the device then.
• When the phone is booted, enter the command mode again dial - *#197328640#
• Select the Debug Screen, normally option 1
• After that, choice phone control, option eight
• Click on nas control, option 3

Please how can i remove invalid IMEI lenovo A520 baseband version A520.H001

Proposed solution: uninstall Google Chrome Frame
I discovered the pb yesterday, trying to connect to Facebook on my XP SP3 Win32 desktop that runs fine, but on which I rarely connect to Facebook, so that I don't know for how long the problem has been here (days, weeks, but no more)
I struggled in various forums to find hints others than "use Chrome or Firefox" etc...
I finally found the solution hidden in:

After uninstalling Google Chrome Frame, I just had to quit IE and launch it again.
Many thanks to "Lexington Computer Repair Blog " and Sue W (who hold the solution from a Facebook forum)

im sorry sir ,the only thing we can do in this problem in the dct4 (3100 ,7210,3530 ,6610 etc) problem is changing IMEI and its already unblocked..but because of the new security of NOKIA on this what we called BB5, baseband 5 phone 3110c ,n70 .3500v etc ,even if we change the IMEI ,your phone is in phone restricted or maybe contact service status...so sad to say ,no solution in your phone sir..thanks
