[HELP] Suddenly can't detect SIM card - Nexus 5 Q&A, Help & Troubleshooting

I've seen a ton of "Sim Card Not Detected" threads here and elsewhere, but I think I'm having a different problem. It started yesterday, when my phone spontaneously rebooted (just looked over and saw the boot animation!) and came up saying "No SIM card", when it had been working fine a minute or two before. Since then I have tried:
* Rebooting, many times
* Reseating / cleaning the card, many times, both while powered on and off
* Cache wipe
* Factory reset
* Reflashing from factory image (m4b30z)
Here's where it gets strange. I get no GPS lock in Pokemon Go (grey pin in Google Maps, I haven't installed a dedicated GPS tester yet). I also don't seem to be able to rotate the screen -- I have checked that Auto-Rotate is enabled but it stubbornly refuses to change orientation when turned. All these things worked fine yesterday morning, so I have to assume the failures are related.
If a factory image flash doesn't fix it, I'm guessing it's not going to get better, but I'd at least like to know what kind of (hardware?) failure could lead to all those things going wrong at once. Is it worth bringing to the local repair shop (out of warranty, obvs) or do I just leave new Android iPod at home forever and start phone shopping tomorrow?

Sounds like a hardware problem since the software changes and resets did not resolve the issue.
If the screen and body are in good shape, I would look for a used Nexus 5 with a smashed screen and working motherboard to perform a motherboard swap. It's very easy to do.

Iam there too, seems last update broke something, iam switching to a custom rom

wifi problems laggy, crashing

hi all.
As I mentioned in my other post I have been having some serious wifi problems. Basically if I leave the wifi off the phone seems to work fine. When I turn it on however, the phone becomes laggy and it does not work. After turning the wifi on from the settings page, it says it is scanning for networks. After 20-30 seconds a little bubble pops up and says "unable to scan for networks" it will continue to try and scan on and off but never is successful. The phone is better to start up with the wifi off because if on, the phone becomes almost unresponsive and I am assuming it is because it is trying to scan in the background.
I just rebooted into the recovery menu and wiped the cache and device, but no luck. Any other ideas as to why this is happening?
Little update:
I found a few other threads where people complained about the same problem. Their recommended fix involved removing the file "/data/wifi/bcm_supp.conf"
The full thread is here: http://androidforums.com/samsung-moment/46179-unable-scan-networks.html
I tried that and also did a factory reset but unfortunately have not been able to fix the problem. Does anyone else have any other ideas?
hi Scales11
I'm also having the same problem..
did the
1. factory reset
2. new ROMs - Darky 7.01, Cognition 2.3...
3. delete the /data/wifi/bcm_supp.conf file
and still no luck... and realised bluetooth isn't working either..
anyone?? please help?
If you have flashed other ROMs and still the same issue. I would say its a hardware issue.
my fix
Geekboy9:
I meddled it for hours and while others have found various odd reset/rom fixes, I concluded that it was a hardware issue which cannot be fixed.
I flashed it back to a stock rom and went to att. They agreed that it didnt have any water damage and gave me a number to call about getting a replacement. Since the phone was less than a year old and its failure was not due to my use, the replaced it with a refurb. All in all the refurb seems fine, even after I rooted and flashed the cognition rom. I would recommend you do the same.

Frequent freezes of S2 LTE (I727R). Not sure how to resolve?

I am having a very annoying problem with my Rogers I727R S2 phone on ICS stock.
The problem started to increase in frequency to become a real pain.
My phone would suddenly freeze and stop responding to screen touches for a bit, sometimes as long as 2 minutes, before bouncing back. When it comes back, it initializes as if it is restarting, so I would feel a vibration, lose all open applications and see icons start appearing on notification bar one by one. The media scanner would start working and software installed on SD card start appearing.
The problem happens spontaneously and out of the blue. It was occurring at less intensity on gingerbread before upgrading to ICS. After upgrading, it was not that frequent until only recently.
I noticed the problem goes away when I remove the SD card or when I am on flight mode with no Wi-Fi. I changed the SD card but this did not help. Connecting from home or work does not differ, so a problem with Wi-Fi would be ruled out. I once had a problem with home Wi-Fi when somehow the router’s DNS was not resolving, when this problem of mine was at its prime, and my phone was rendered unusable as it only takes couple of minutes before acting up.
I spent quite long time searching for an answer and so far no luck
I just placed a video illustration of the problem, and hope to get feedback on even where to head.

Try a different launcher.
the only way to troubleshoot is to start from scratch, read my 2nd link in my sig to restore to stock ics, reset within the recovery when odin finishes flashing, also keep out your sdcard out just to make sure your sdcard or its slot is not the problem. if still having probs its hardware failure, should still be under warranty

I went through your instructions restoring to stock ICS (which did not wipe my data as I thought it would). This did not help though, and the problem persisted. After that I decided to a hard factory reset. This appears to have done the job and my phone was working very smoothly.
Because my phone is rooted, I restored to the buggy stock again using CWM in hope to be able to figure out how to my migrate my purchased software, data and settings after hard reset. I wonder if there is a way to preserve important files even with replacing systems. I want to hard reset again but I keep my important information

after restoring stock perform a reset in the recovery, if old data is still there after reset its a hw defect in the nand

*desperate* sudden Airplane Mode lock / zero radio

N5 purchased direct from Google in early spring, has been used as daily driver since then with little issue. In official hard silicon case since day 1.
stock 4.4.4, unlocked + root. Rather innocuous app list (TiBU, F-Droid / AdAway, etc)
Recently after a reset to attempt ridding of some minor issue (funky reception or something), upon finishing boot, phone didn't ask for SIM pin, as always prior.
Quickly revealed because phone does not even detect SIM. Different SIM from another carrier attempted. No difference. Original SIM also attempted in a different N5, still works. So problem appears to be with phone.
Nothing of note to precipitate this happening. Power menu shows Airplane mode is ON, but cannot be toggled. Quick Settings Airplane Mode can be toggled on and off and icon does change (so sometimes contrasting what power menu reports), but SIM never detected / activated / used, ZERO radio available. Attempts to make calls say "first disable Airplane mode". Many attempted combinations of SIM in / out, Airplane Mode in quicksettings toggled, resets, etc. No dice.
Everything else works with the phone, this came on suddenly.
Tried reflashing same radio. No dice. Tried flashing 4.4.3 radio. No dice. Tried factory reset and also re-flashing entire phone to 4.4.4. No dice.
After all that I am led to believe this must be a hardware issue, but I wanted to know if you guys had any suggestions before forced to send back in to Google.
Googling reveals some other instances of this happening to people, but no real solutions provided. Why would the hardware suddenly just die, and why would it present itself the way it does?
Side note, if it DOES go back to Google, does anyone know how to avoid getting refurb in return? That is all they are offering and will not budge. Yet less than a year ago I had to replace an N4, and received a new replacement, without even making a particular request for it.
Sounds like your radio hardware has gone bad you have done everything to troubleshoot software issues RMA it to google

Wifi / Bluetooth / Sim Card Issues Since Last Two OTA Updates

I received an OTA Update in early to mid May. I am now forgetting which version I received at that time. ( I forget as I have done so many downgrades/upgrades/factory resets in my troubleshooting the last month!) Up until these issues, I've never rooted or flashed a ROM, or unlocked boot loader or anything. My N5 had always been completely stock.
First Issue
It all started with just the sim card. I get "no sim card" message, even though it was in there. This was my original SIM card and I had never ejected it since I bought it new. I found I could turn it off, pop it out and back in, and boot it again. Sometimes it will see the sim card again. It may take 20 times, but finally work.
I naturally got a new sim card, as well as confirmed said sim cards worked in other phones. My wifi and bluetooth were working fine at first. Working with google support, they recommended a factory reset to fix the sim card issue. Immediately after the factory reset, my bluetooth would no longer turn on nor show a MAC address. At this point, my wifi was fine.
Second Issue
In addition to the sim card slot issue, now my Bluetooth no longer works! Around this time, I received another OTA update, this time it was 5.1.1 LMY48B. I had hoped it would fix the issues, but no dice! I start reading up on the XDA forums as I am determined to start rolling back to see if this will fix anything. I unlocked the boot loaded, rooted, etc following the threads on XDA
Third Issue
I do all sorts of flashing to hammerhead-krt16m_4.4 to hammerhead-ktu84p_4.4.4 to hammerhead-lrx21o_5.0 to hammerhead-lmy48b_5.1.1 . On the final flash back to 5.1.1 my wifi now no longer works!!!!!!!!!!! It is stuck at wifi turning on and no MAC address shows. It also seems my cell data is very very slow now!
After many calls to google, I think I finally succeeded in getting a “ticket routed up”. My phone is from the play store around 10/31/2013. They keep pushing I am out of warranty. I attempt to ask for a refurb N5 without luck so far. I am not very confident anything will come from google. This being my only handset now, it is just not an option to send this to LG. My current state is my voice/txt and cell data are working. Data seems a little slow but usable. Wifi and bluetooth won't turn on. I also still have the sim car slot issue upon rebooting. After a bunch of reboots it will eventually see sim card.
What else can I try? Is there a better way to attempt to repair/reload my radio drivers? Perhaps there is corruption of sorts? I have not tried a custom ROM or radio or kernel…… I did take to a local tech. They looked at everything literally under a microscope and did not see any issues that way. I am in the USA and have a lgd820. Although we are quick to assume a hardware issue, I am wondering if there is some sort of incompatibility with the first run of N5 and lollipop….. who knows!
I’ve read all sorts of threads on the internet. It seems I am not the only one. We are very quick to assume it must be a bad motherboard, it just seems too coincidental to me!

Hi,
This link was actually what i was going to suggest. It seems you've tried pretty much everything in the book except that.
I think its worth a try. Same as any other learning process, take your time and read the whole thing once or twice until you feel comfortable with the process. Then go for it.
Darn it, I should have downloaded those programs BEFORE rooting my phone again. Now I a struggloing to get my SIM card detected again to get data to DL them! whooops!
How would I go about attempting to read my files first to see if they are accessible and potentially write down my old MACs first?
EDIT: I found this but not sure how to get that working? I have Windows 7 and CMD prompt at this point. what program is that using?

OK, I went through those steps. everything appeared to go through correctly. Still no wifi nor bluetooth
EDIT: I rebooted a second time. WHen it first boot up, wifi was on and connected to my works AP. I quickly went in and snagged a screen shot of MAC address. Oddly enough, it did not match what I had input via hex editor. Within a few moments the wifi stopped working. It is back to the turning wifi on issue..... bluetooth still not working as well.
Very interesting.....
EDIT2: I get access denied when attempting to read either files within their corresponding folders under persist.
I was able to copy my stock files into my sdcard download folder and read them there without issue. Thus seeing my default addresses for both!
Perhaps it is normal, but I am never able to edit the old or new files under persist. I basically renamed original folders to bluetoothold and wifiold. I could delete them perhaps.
Note that I put my phone into airplane mode before doing anything noted in the steps.
Any other ideas? Given that it is showing my original MAC address the one time it worked, this makes me think that it is not reading the files .macaddr at all
I have the same problem. Funny thing is, the phone is just over 2 years old and the motherboard was replaced just 9 months ago (so, brand new one).
In my case, I received and Android update 2 days before I found the phone burning hot and restarting on it's own. Then the same chain of events you describe started to unleash. Now I can't be sure if this is software related, hardware related or both.
Can't seem to find a solution to the issue either.

I'm facing the same issues and I tried all the possible steps I could find on internet trying to repair the problem.
Actually, since the latest updates I was encountering some issues with the WiFi only: not turning on either off and not showing properly the MAC addres. So I decided to factory reset, even SDcard and since yesterday I have tried all the possibile guide I found to internet to fix the MAC address not showing and the WiFi not turning on/off but nothing worked. I tried even to flash again the old factory images, such as KitKat, Lollipop, etc., to lock the bootloader again and to dismantle the phone in order to clean the motherboard, but nothing worked. Phone still gives me MAC address 02:00:00:00:00:00 alternatively with the correct one, I can't figure out on what it depends because sometime it seems to work: it shows the correct MAC, it connects to wifi network; suddenly it doesn't!
I'm really going crazy to understand what's wrong.
You'll have to dig up my final posts on this , but in a nutshell, send into LG for repair, select cheapest option they offer. Receive mint phone. My cost was $45 and about one month... I picked up a cheap $20 phone to get me by.
In other news.... I now have a 6p!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Strange and significant reset and camera problems after latest update

I've got some very strange issues happening since the latest T-Mobile update to baseband G930TUVU2APC8.
The phone is a T-Mobile Galaxy S7 with a Sandisk 200GB micro SD card installed
Whenever I'm on a phone call through a my Jawbone Era (and charging; I haven't tried it unplugged) the phone will behave as if it did a reboot, without actually rebooting, every few minutes. The phone will stop responding for about 20 seconds, then show just the wallpaper for about 5 seconds, then go back to the lock screen. At this lock screen it requires me to enter my password instead of using fingerprint as if it had just powered up. The phone call does not drop through all of this.
The next issue is that some pictures taken from the quick launch are sometimes not saved. I'm not 100% sure that this only happens after the reboot issue above, but I think it does. I have secure startup disabled .
I tried a factory reset which did not fix the issue, contacted t-mobile and was sent a replacement device that still has the problem. None of this was happening prior to the latest update.
Has anyone else experienced these issues? Also, is it possible to downgrade the firmware version?
Thank you,
Matthew

The problem started in PB8 firmware, PC8 firmware has constant wifi dropout issues, you might find even that at 3G connection performing better than fiber optic wifi internet.
Easiest is to update facebook to latest version and see how many "can not connect right now" errors.
Random reboots is normal never mind how many times your factory reset or do a full firmware PB8 flash.
T Mo is not the brightest tools in the shed, it takes 5 visits to their T Mo offices to get the accounts and products purchased + refunds for items payed in cash or freebies refunded etc etc etc.....
