HTC GPS Problem

Issue of the GPS :
GPS searching forever, no fix, status bar does not even show the GPS-icon

Highlighted Solution :
There is two method, but the second method is dangerous as it have the risk of making your phone an expensive brick :). So I just post the first method okay.

Method 1 : Removing the efs-data using vision_wipe_efs

1) Download vision_wipe_efs from vision_wipe_efs_01.zip (md5sum7bced5385509a58a7c8b0a54d38a6897)

For your information : The program vision_wipe_efs will create backups of the partition 13 and 14 on the sdcard using the name "/sdcard/part13backup-<time>.bin" and "/sdcard/part14backup-<time>.bin" so make sure that the sdcard is mounted to the phone.

2) Unpack the zip file to a directory on your PC(Desktop?). Open a terminal (or command window) on your PC and change the current directory to where the files are on your PC and execute this command (as always: do not type the # it only indicates the root prompt in the shell or the $ as the prompt in a non-root shell):

Code :

# adb push vision_wipe_efs /data/local/tmp/

*** You can use other method to copy. ***

3) Get a root shell on your phone (either using adb shell or a terminal app) and then use the following command:

a) If your prompt is not # but $ then first do:

Code:

$ su

and answer the question of Superuser. (Well you should all know this by now :-) )

Code:

# stop rmt_storage
# chmod 777 /data/local/tmp/vision_wipe_efs
# /data/local/tmp/vision_wipe_efs
# reboot

There's one more way to do it. You can download  the Zip File HERE. AmazingLarry has created a script of guhl's efs wipe and made it flashable through recovery.
