Sorry, I didn't think - [MENTION=1392348]pandeyshreedhar [/MENTION] and [MENTION=7408621]Oswald Boelcke[/MENTION] are right. Here is my original posting:

"Need for assistance

I'm an amateur (learning-by-doing) who have just updated my Samsung Galaxy S3 from Android 4.4.4 to 6.0.1. The update was only a semi-success, however. The success part was that I manage to ressurect the phone, which soft bricked (I think) on a first trial to update to Nougat, and flash Marshmallow from cm-13.0-20160907-UNOFFICIAL-i9305.zip. The success was only relative, though, as I lost my connection to the sim-card (all the cellular settings are greyed out), and also cannot connect properly to my PC. (It shows in Computer, but I cannot exchange any files with PC.) I have tried to delete and download drivers again, but the phone shows up in Device Manager only as Samsung Android Phone and there an Android ADB interface below it. However, under Other devices there is an Unknown device with no drivers, which I have sought for (I guess they should be for MTP). In addition, so far I haven't been able to download gapps due to a premature reformating of my sd card in the set up of the phone on Marshmallow, but I think I can manage that part. However, without an AP connection with my carrier (Telenor) and a file exchange connection with my PC, the phone is useless to me. So I wonder if I made a mistake in the updating process, e.g., in preparing the tar file for flashing? Or perhaps this particular version of Marshmallow does not fit my gt-i9305, which is a Norwegian phone operated by Telenor? Could anyone advice me - are these problems fixable without deleting what I have built, or do I need to begin from scratch and download and install a new operative system? Which one, in that case?

The solution to the first problem was simply that I had overlooked the modem file: i9305-modem.tar. When I flashed it with Odin the cellular settings and the IMEI number came back. The second problem was that I didn't realize that I would have to manually change the USB connection from charging to file transfer (it as automatically connected to both on KitKat). I was also eventually able to download to my sd card the right package of gapps (arm) and install with TWRP Recovery; I had to reformat the sdcard (since I had too quickly accepted that it be integretated into the internal storage).

Since then I have updated further from Cyanogenmod Marshmallow (cm-13.0-20160907-UNOFFICIAL-i9305) to LineageOS Nougat 7.1.2 (lineage-14.1-20171128_075344-UNOFFICIAL-i9305-ci) built by [MENTION=5486550]p.a.n.[/MENTION], partly because I got a problem with malfunctioning camera (which is widely known and discussed here at the forum), and also because I wanted to have the newest possible Android Version for my phone (without building one for myself, which I haven't got the know-how to do quite yet), and to be on LineageOS. It took me a whole day to be able to install it - lots of unforseen problems foreseeable arised, such as soft bricking the phone, inability to flash the gapps because I choose arm64 package instead of arm, too big a package, and more) - but now my phone is up and running on Nougat, and so far I'm very pleased with the result. It is also satisfying to be able to withstand the pressure from the phone industry to purchase new phones all the time. It is possible if you are diligent at it (and think it is fun, even if it is often frustrating).
