[General Questions and Answers] road666runner:
Hello all, I am having a problems with the USB connection of my phone since 2 days. The Samsung Galaxy S3 GT-I9300. It suddenly won't charge (very rarely it does ) and I cannot connect to any computer via USB. You simply don't hear the USB sound, no device is detected. The funny thing though, when I go to download mode, the device is found instantly, and I can also flash the device with Odin, as I have done several times, trying to fix this problem. This suddenly happened two days ago, I didn't change anything, it simply stopped working from the one day to the next.

I have searched and read about this issue, and I found out about epic dialer codes.

this code is working : *#7284# (I had to flash to different firmware to get it to work though), i am now on this firmware:

GT-I9300_PHN_I9300XXALE8_I9300PHNALE4_I9300XXLE8.tar

The problem is, there should be a Qualcomm USB option, but it simply isn't there. I have read that many others have the same problem(no data connection and no charging) and they fixed it trough that setting. I also found that dialer code *#22745927 should enable this function, but this code is simply NOT working!

Also *#0808# doesn't work, I really want to use my USB data connection. I have 5 batteries and also a wall charger, so I am not worried about running out of power, and I am also sure it isn't a battery problem. I have 2 data cables, I can use them both to flash the device in Odin, when I connect the cable when the telephone is Off, I can see the battery for 10 seconds, but then it disappears and will not charge. (very rarely it does)

How can I enable the hidden menu and get to the qualcomm USB settings??? I also tried the app "Secret Codes Revealer" I have flashed Beanstalk, CM 10.2, in every firmware I cannot get the data connection to work. I am now trying different firmwares to get to those *#@! Qualcomm USB settings

Please help

Try this: *#22745927﻿

*#22745927 doesn't work that's the problem I think

Apparently several people are having this issue, I will now try to flash verizon firmware to my vodafone device, to see if I can get that option to work, and afterwards flash it back to CM10.2

OK, I found out the following: the Galaxy s3 for US and Canada is a different model, the SCH-i535, and the qualcomm settings only apply for that phone, It's a little confusing, but the option apparently doesn't exist on GT-I9300 model.

That guide doesn't apply to you; the Qualcomm related stuff is only for the US and Canadian Galaxy S3 models; they have a COMPLETELY different chipset (Snapdragon S4 instead of Exynos Quad). Do not follow that guide.
