[Windows Phone 8 Q&A, Help & Troubleshooting] Kepavi:
Hello everyone, hope I will get at least some answer to my issues that I am having with my Lumia 1520, otherwise, I will just throw it away and get back to Android (which I would really like to avoid).

Anyway, a while ago, as in about a year, I have jumped on Fast ring on my Lumia 1520, Wind Black edition (not network locked).

As time passed by, it was ok experience. Yes, WP had issues, and what not, but overall everything worked ok. I got my phone Dev unlocked while it was still on 8.1 but never fiddled with any interops, hacks or anything like that.

So, somewhere after they have removed Astoria subsystem, I started to experience some game breaking issues. Namely, computer doesn't detect my Nokia at all anymore. Mind you that it is not cable issue, it is not port issue, and since a friend of mine also on 1520 experienced the same issue (also on Fast ring), as well as few people online that I saw, I highly doubt it is hardware issue. As said, in one Astoria included build, I had no issues connecting phone to computer, pushing Android apps, removing them etc. Then on, I think that it was next build when Astoria was removed, but I cannot say for sure since it was long ago, and at the same time I though it was a bug in Preview version (which you can expect considering its developers build), and as said, friend also had the same issue.

So basically, when I connect my Lumia to computer(tried on few different computers, havent tried on Linux since I don't have one and heard that its not working on virtual machines), I can hear audible ping from the computer that something is attached, as well when I restart it (Vol Down+Power) I hear audible that something is removed. Phone charges fine via wall charger, as well as with USB, with notification that "Phone is charging slowly" with USB to PC cable...

However, during both cases, I don't see anything pops up in Device manager, nor gets removed after removing Lumia. Obviously, I cannot roll back to 8.1 since Recovery tool doesn't detect it either. I recall that at one point, I have tried following. Attach phone, run recovery, restart it and press Vol Down so that Exclamation mark pops in and during that time recovery detected the phone and started downloading some image. That is how I figured out which my product code is 059V743 RM-937 IT Wind Black. Figured, well, if I get pissed too much, now I know how to get recovery to detect my phone. Except with the latest build (10586.164) it no longer works. Apart from that, phone works just fine.

I have noticed when I have removed Nokia Recovery tool (had both since both were on Windows site to download), once phone was detected as Nokia Boot Mgr or something like that since I didn't paid attention and it installed the files rather quickly...

So, any info on what to try, or where to look (I did searched but nothing that I have googled worked), is much appreciated. As said, tried on different computers, different cables, some also have the same issue, so please skip those advices since I have already tried it. Phone didn't dropped single time, didn't jerk the cables and anything similar, so I doubt it is HW issue anyway.

Thanks and sorry for the long post
