Db2020 Call Fail After Unlock
 

Dear Infinity team. I have unlocked a couple K800 and W850 units successfully via davinci team. However on 2 of these units after i unlocked them i was able to make calls on 1900 but not 900 Mhz networks. I tried flashing debranding etc with both davinci and cruiser but with no success. I had to pay for flashing and thats a waste for nothing. Can you tell me if your flash will unlock or allow me to use the european frequencies. I had the problem with Vodafone and 3 network. Thanks in advance. I know this because here we have both US and European networks.

Hi ,

we can not promise you if your phone will be repaired or not ,
try to find the firmware version that was existing before you unlocked
and flash it back to the same , check manually band selection in network settings

Ok this is not a band selection problem or a problem that any user settings change can solve. It is a method of locking the phones so that the can't be used in another region. I had discussed it with the davinci team and they told me that the problem is in the GDFS area. Can you flash that region of the phone?

If you write GDFS fully from other phone then u can put RIP on it after.

Br;)

full flash ur fone with settol only one credit ..all will be well

Yes i suspected that. Thats why we need to flash only the relevant part of the GDFS. If this is not possible then the phone really can't be unlocked for use on our 900Mhz network.

i dont think this solution can sort out the problem bro. :)

do previously it was working with 900mhz than there is no use to unlock and use.
