G810 won't start
 

Hello,

I have an G810 and i tried to upgrade the firmware with apollo 4.21.

For the first time i tried modem download - it works but won't get tot the finish so i had to take out bettery from the phone.

Since then only pda works and my phone frezees at Samsung screen.

I read somewere that i should leave the phone without battery for 24 hours.

What shoul i do?
Please help!
