[Nexus 6 Android Development] internetpilot:
Actually, I waited for the SIM card for over 24 hours, because I originally thought it was a SIM card or hardware (SIM card slot) issue when I first encountered it. I'd never heard of flashing a ROM (especially one without a radio included) resulting in not seeing the SIM card. During this time, I was just running everything off wifi until I made it into the Sprint store to get the SIM replaced. When that did nothing to solve the problem, I was thinking I was going to have to send it off for warranty repair/replacement, and then as a last ditch effort I restored it to stock and the SIM card was back. I then clean flashed the April update of PN and still had the SIM card. Flashed the May update (first dirty over the working April update and then clean), and my SIM card couldn't be seen (both times). The exact same thing happens with the June update through the same scenarios.

I've been running 32R ever since I noticed it was available. I tried 34R, but it didn't do as well for me as 32R. I've tried flashing 34R after flashing the May update, but it did not resolve the No SIM card error. I've also tried the same with flashing 32R after, and no joy.

I cannot update the PRL because I have no connectivity with the No SIM Card error, and the PRL won't update over wifi. I don't have an APN on Sprint.

With all respect, the only way I'm going to mess with the EFS partition is to flash a different radio, which I've done after getting the "No SIM Card" error (flashing both 32R and 34R) and it does not resolve the problem. Given that I can flash whatever radio I want on any PN update prior to May with no problems and flash whatever radio I want after flashing the May or June update without it solving anything, I'd have to say that the EFS partition isn't the issue. Plus, I've been emphatically and repeatedly told by both PN and Dirty Unicorn devs that the the EFS partition isn't touched when flashing their updates.

And if the ROM doesn't see the SIM card, you can't update the PRL because it won't do it over wifi.

And I really appreciate that! Thanks for the help/suggestions. This has been a real puzzler for me. I usually solve my own issues, and rarely encounter issues at that.

As of now, I flashed back to the 2nd December update of PN and everything is working fine. I chose to go that far back because I'm trying to avoid another annoyance that popped up when clean flashing the April update where the N6 prompts me for approval of access to SMS every time I connect it to bluetooth in both my vehicles. It didn't used to do that and hadn't done that while I was dirty flashing the updates all along. It only started happening when I clean-flashed April. So, I'll probably still update to April, but I'll probably do it sequentially (dirty flashing) just like I originally did so I hopefully won't get the bluetooth annoyance. I like this ROM (because it's basically stock with the few bells & whistles features that I want), so if nothing else, I'll just remain on the April update indefinitely. I am admittedly worried about what's going to happen when this ROM is updated to Android N, though. I'll probably have to move on then if no one is able to figure out why this has been happening from May builds forward. I was actually hoping the June rebase would solve the problem, but unfortunately not.
