[Galaxy S III Themes and Apps] Jumbodriver:
Easy UMS and PC's

[OFFTOPIC on]

After reading through more than 720 posts I have the impression that I am one of a few spending the whole afternoon in reading. Some Questions are asked over and over again, even if the answer was already given. Thats why I decided to try to give some more explanations to some problems that occur with this app.

I dont want to step on anybodys feet and most probably some of the PC Geeks will say: "I know this". I just try to explain it a bit more foolproof.

[OFFTOPIC off]

The problem with this nice little app is, that the problem sometimes resides on the PC and the app is working fine, so here are some hints.

This is for Windows.

First of all, as a basic rule (and that is true for any USB device) -> the driver needs to be on the PC BEFORE connecting the device. If this is not the case, the wannabe-intelligent operating system tries to find a matching driver and it seems, it sometimes gets the wrong one (see the first post, on how to get Win7 to find the correct driver)

How to get the right drivers?

I simply installed Kies (Like it or not, the correct and latest drivers are coming with it). In order to avoid Kies from interfering wenever I connect my phone I disabled the autostart in the Kies options. After this step I checked my phone if USB debugging in the developer options are disabled, because I didnt want the ADB drivers to be installed at this point.

Next step: The phone needs to be rooted and busybox installed on it. I used mskips toolbox to root and install SuperSU and busybox (BTW my phone is a S3 LTE 9305 running stock Jellybean 4.1.2). After installing Easy UMS 1.8 I connected my phone to the PC, waited for the drivers to be installed, started easy UMS and switched to UMS. Wait a few seconds for the USB drivers to be installed and thats it.

On Win XP I had two driveletters and on Win7 only one, because Win7 does not show non accessible drives (see your CD/DVD drive - its not there as long as there is not disc in it).

Now you should be able to see the files of the external SD. If not there could be a problem with the filesystem. Win7 has a build-in exFAT driver. Thats not the case for WinXP and afaik also for MAC and Linux (not sure about it). Easiest way to check this is to take the SD card out of the phone and connect it with a card reader to the PC. Use google or the search function of this forum to find the location of the driver. It has been mentioned before. The other possibility is to reformat your SD Card to fat32 using a third party tool (Also mentioned a few pages back).

Using fat32 might also help with some car stereos to read your mp3's.

As I mentioned before.... No offense for the pros, but I hope this few lines will enlighten the noobs and solve a few questions

rgds. and have a nice evening

... just another quick idea...

those of you having a problem to see the external SD on a PC: Maybe you want to try boting your PC from a live linux like Knoppix. This avoids any fancy driver or software interfering.

I just tried with Knoppix Versions 5.3.1 and 6.0.1 In both I was able to access my external SD (of course only if it is fat32 formated). At least you know if the problem is in your operating system.
