5110 not working properly!!! HELP

[Yasser]

Dear All

I have two 5110. I used a full flash file 5510 V5.30 so that I can update the firmware versions of both phones. I used the Dark Lemming Shell v2.14b. I managed to upgrade the software but now the phones dont show any signal when i put my sim cards in. Also, these phones come on and off after every 20-30 seconds by themselves.

Can somebody please tell me how to sort this problem out and with which software.

I will be very grateful for the help.

Best Regards

Yasser

You cannot upgrade software just by flashing in this way.
Restoring your phone to its original version will cure the problem go to this link -http://www.unlocker.cz/html/flash/flash_nokia.html
