samsung s3 neo ubports install

AppLee

Hi and welcome @fikirsancisi61
You mention S3 Neo, the port is available only for Samsung S3 Neo+ (GT-I9301I)

I also moved your post to the dedicated sub-forum in case you have a S3 Neo plus.

@fikirsancisi61 You see in the error window that Heimdall has issues flashing the image. Can you scroll to the right inside the window and copy all that text into here, or find the installer log file in your PC, it should tell us whats going on.

Ok seems Heimdall cannot access your USB port. Can you try as Admin? It can also be necessary to isntall udev rules for Android adb access, you can try to Google that.

Hi, check my post, I had a similar issue, and as others said it is only for the GT-I9301I (S3 Neo+).

I struggled to get it to install from a windows machine (windows 10) so use Ubuntu instead. But:

1)Make sure you have Android tools installed
2)Make sure you have various USB cables to hand, Samsung phones are particularly finicky on USB cables
3)Do not run the ubuntu touch installer as admin
4)Libusb errors are usually down to an incorrect driver, install the Samsung USB driver and see if that changes anything - it is why I switched to my Ubuntu machine to install (I had a libusb error -11 at one stage) as USB just works unlike windows.
5)Persevere and ask questions, sometimes just asking will change a thought process that has railroaded you down a dead end

It does work, but read Flohacks report on what works and what does not (i.e. if you want the rear camera, at the moment it isn't functional). Also these phones are old, I have some that are pretty good condition, but the battery is old and won't hold a charge, getting a good battery isn't easy, I have bought a few duds.

(If you try the install on Ubuntu, install Heimdall, it is known as Heimdall-flash now).

If you need any advice, keep asking.

@fikirsancisi61 Windows 11? Sorry we dont test for unreleased software ^^

Another thing I have discovered is the USB port isn't too accommodating with certain USB cables. To solve this, I fold a piece of paper and when inserting the cable, put it on the bottom of the cable connector as I insert it. This holds the cable in tight (all the USB contacts are on the top of the connector) and the phone won't lose communication with the PC if you move it, nudge the cable, breath etc.
