[Galaxy S III Q&A, Help & Troubleshooting] xaser66:
Hi!

Well, I finally got my usb work and was due a combination of wipe and original cable (and combination of this factoirs in my previous attemps...so I would like to thanks again to JJEgan since with their "standard reply" kick me to start a new round of tests and I found some details that would like that would like to share if may help somebody else that may look in this thread....

As many other people post previously thet Samsung original cable that came with S3 is really faulty (as many others friends found and post before), but I didnt found in previous posts if somebody look why this (simple after fix didnt look more about), so I was curious and checked it, and at least to my sight (that not may be the 20/20 but close, and I checked with a magnifying glass...), so these are some details that appears to my eyes:

1) The Samsung S3 usb conector seems that have somewhat more tiny contacts plate that other phones (including samsung as I checked with my Captivate Glide), so the contact with a cable seems to be somewhat loose in many cases...

2) In my case the diference was with a Droid 3 oem cable that when is checked carefully against the Samsung S3 original cable and Samsung Glide original cable, the Moto oem seems that have the internal wire contacts inside the micro usb conector of the usb cable, more "curved" to the center of the slot of the micro usb cable conector that the Samsung ones (in fact the Samsung seems almost planes in comparison). So I believe that my previous attemps with Moto cable may fail because I didnt full wipe my S3 at that time of test with moto cable.

3) I also receive and tested today an HDTV Adapter TIP (5 to 11 Pin Converter-Samsung EPL-FU10BEBSTA) and I gald to confirm that It works wonderfully with my Glide HDTV adapter (Skiva MHL (Micro USB) to Female HDMI Adapter (1080p Supported)), so it seems a fine piece, BUT the curious detail is that this HDTV Adapter TIP have a really visible longer metalic connector (more than 1mm more) that the metalic connector in the S3 original cable, and when the HDTV Adapter TIP is inserted in S3 it goes fully inside (so apart of somewhat tiny internal plate, seems that the connector is in fact more deep inside S3 than other phones).

4) I also tested the moto cable with HDTV Adapter TIP and it didnt work to make a data transfer connection but make charging of S3 so the connectio is made but not recognized through the HDTV Adapter TIP for data access (but again HDTV siganl of the Skiva adapter works fine).

5) So, my resume for people that may have this issue is:

a- Find a usb cable that may have more curved wire contacts inside prefer oem cables that may have better quality.

b- Test on a windows machine with the LAST AVAILABLE version of KIES and allokies to download their last driver version that may it install.

c- When everything is set, if possible test usb cable and port in copmpuetr with another phone and better if could be another samsung model so You could check that kies is working fine.

d- First plug usb cable in computer and then in S3 and if nothing happen try to move VERY GENTLY AND SOFTLY the micro usb plug connected in S3 in order to try that the really tiny wires of the plug may reach god contact, or try several times to plug and unplu micro usb connector in S3 port (try counting to 10 between plug-unplug).

e- if the above didnt works I may suggest try on another coputer that may have win 7 in order to test better.

In my case the diferences was made with step d of the above comment.

So, by now thanks to people that read this post and best regards to all.
