Hi

 

I want to update the os system in my acer e350 hmhameh001. But everytime when i start the  update it refuses and is asking for a sd card. The current OS is the original one. 4.0.3.

 

I have updated the OS system in the past without a sd card. But i had to repair the phone and the reparing company did put it back to the original OS system.

 

So it must be possible. but i can not find out why it is not working. can somebody help

 

regards
