IPhone 3g/3gs (locked) baseband and navigation functions

PS: no navigation function is available after upgrade to baseband 06.15,

Unless your iPhone baseband is already 05.14 or 05.15 and you need to upgrade it to 06.15, we recommend that you do not upgrade it for the time being.

PreviousIt cannot be downgraded back to the old baseband. Now the new version can be downgraded back to the baseband, but some machines still cannot be downgraded, depending on your luck.

My personal character is guaranteed, and the baseband is downgraded once. By the way, the US at&t activation card is provided to friends who need it.

3gs 06.15 the baseband network says it cannot be navigated, and it has never succeeded. However, you are skeptical about navigation.

 

The final conclusion is:

1. I do not know whether it is related to the baseband.

2. The navigation function is related to whether satellite signals can be received.

 

Solution:

1. Install the navigation software.

2. Use baseband 05.13.04 (not sure whether 06.15 can be navigated)

3. Install the GPS kit package (search 91 assistant can help you upgrade to a newer version)

4. When you need to navigate, first turn on the GPS kit software for a few minutes, then turn it off, and then turn on the GPS navigation software.

5. If navigation is possible, it indicates that the satellite signal is obtained successfully and cannot be sent to the airline. 4. It is generally successful once outdoors.

6. After the channel satellite signal is lost, you need to re-4 or 5 to continue navigation. Otherwise, the navigation fails.
