After updating to baseband 06.15.00 with RedSn0w or PwnageTool and then unlocking with UltraSn0w, many people started reporting about GPS not working and battery drain problems. We have already shared a temporary fix for battery drain issue. About the GPS issue on baseband 06.15.00, checkout the Dev-Team’s comments after the jump…
Unlockers have been reporting mixed results about GPS functionality at 06.15.00. Until we can track down what differentiates those who retain GPS vs. those who lose it, be conservative and assume you’ll lose GPS at 06.15.00. As we work on finding the cause (and possibly a fix), please report your personal findings in our comments section. (Update: early indications are that while 06.15.00 is capable of GPS, it will require some further hacks. But please still be conservative and assume you will lose GPS at 06.15, in case the hacks don’t work).
So, the Dev-Team does not currently have a fix for the GPS issue on Baseband 06.15.00 and says that, you should just assume you will lose GPS capabilities when unlocking 06.15.00. However, they are still working on a fix for the problem. [via Dev-Team Blog]
We’ll keep you updated as soon as a fix for GPS on Baseband 06.15.00 comes out. Stay Tuned!
