I got to say, your panic is not going to help. First I want you to take a deep breath, and relax. Now, in order for us to help you. We need to have more information. More specifically, the following: Do you have roo. boot loader unlocked? What carrier are you using? What ROM and kernel you're using? Is your sim good? Are you using a micro sim? What radioband you're using? Is your sim card adapter slot damaged? Is your imei bad? Now you need to put this in a detailed explanation with what you have done with your device up until the point in where your phone stopped working.
stock room,one week old device, no root or nothing similar,the phone doesn't show imei number just blank window (*#06#)

If it's stock and all you did was do an OTA upgrade to 4.2.2 have you tried talking to your carrier? Being only a week old I would use their assistance to your advantage especially if you did not unlock/root the device. (not sure how you came across the sim card, if it was sold with the phone like it was with mine at T-Mobile, or if you just got the phone and then used a sim from the carrier).
but t mobile will send nexus to repair's for a month so do not want to be w/o my phone for so long.I'd like to solve it home...
Today i noticed that my nexus lost gsm signal. Yestarday it was ok and i didnt change anything. So, I turned it off and then on, but it stuck. There is only nexus logo and nothing happens. I had stock android 4.3 with bootloader locked and stock recovery. I tried unlocking bootloader, flasing twrp and wipeing cache/dalvik/data but it didnt help. I even tried flashing PA, but it also stuck on boot logo. After that i tired full factory reset (system and recover) using WugFresh's toolkit, but it also didnt help. In stock recovery there is a red triangle with dead android. Do you have any idea what may be wrong?

You can try this one: Unbrick [bootloop] NEXUS 4 and flash Official 4.3 image [the easyest way]
I have already tried it, it didnt help. But i also tried 4.2.2 and it started after like 5 mins. It takes some time but it boots. But still, there is no gsm connection. I tried flashing diffrent radio but it didnt help. In settings/info there is unknown baseband and no imei. Is this possible that some hardware that is resposible for gsm is damaged?
Check your APN settings b

I bet it's not a problem with apn. When i try to search for gsm network there is an error.
Booting phone takes more than 5 minutes. It shouldnt happen on fresh system.
What is more, info in settings says that there is unknown baseband and unknown imei.

Log above is done without sim card, but it doesnt work even if sim card is inside.
This lane is important I think:
Code:
SCREEN_STATE error: com.android.internal.telephony.CommandException: RADIO_NOT_AVAILABLE
I would try a full factory image restore with data wipe. That might help. If not... May be RMA time. Remember to use fastboot!

Hi I just met the exactly the same problem you described: woke up and found no signal there, and after a bunch of flash things I noticed that the IMEI is gone. All these happened in 1 week after I actually received the phone.
BTW, can you use WIFI and Bluetooth now? Mine is still OK, only IMEI shows 'unknown'.
Hope someone could come up with a solution.

I have already done full factory image restore. The problem is that there is no RMA in my country, the phone was imported from UK.

I recently faced this problem -- booted into recovery and flashed android 4.2.3, still had the issue. did a factory reset which actually wiped nada on the sdcard and as golden after that, re-rerooted and all.

Well, I had an imei before it happned and I still have it written on sim tray. I hope that if I bring it to repair center, it will be fixed.
i have one nexus 4 purchased from Ebay. it has
4.4.2 OS STOCK,
base band M9615A-CEFWMAZM-2.0.1700.97
KERNEL 3.4.0-perf-g2cae413 WED nov 20 14:54:28 PST 2013
build number KOT49H
it has unlocked bootloader, rooted, twrp installed.
it is able to show me IMEI number in about phone and as well as on dialer *#06#
now the problem is, when i insert sim card, it show me no service and no signal in status bar.
so not able to use phone.
kindly help me
Flash the latest factory image.
My N7's baseband version is M9615A-CEFWMAZM-2.0.1700.98, so I think you have the 4.3 baseband which is incompatible with the 4.4 roms, that's why you don't get service.

Best solution is try some another "micro sim".
DONT cut it but bring it from your service provider.

From what I know I believe the sim cards can have hardware within 1/16th of an inch from the side, or it might have been 1/8th but yes dont cut the card, um I know it sucks but back up what you can with something like titanium backup, then try undoing what could be the cause, so flash stock rom. With titanium backup you just hit backup/restore then the checkmark in the top right then scroll way down and hit restore apps/missing apps+sys data... if it fixes the problem then great but put a copy of the backup on your computer in case the extsdcard gets wiped too for some reason or in case you have to send it in

i use following method to downgrade
http://forum.xda-developers.com/nexus-4/general/how-to-how-to-flash-factory-image-t2010312
Ill ponder for a while and see if I can brainstorm a solution, ill ask around a bit and see what I come up with,
If your worried about your warranty and your carrier won't help you, I suggest going to best buy and letting the Samsung guys take a crack at it, they have the proper software to find the problem.
OK when you first got the phone was the sim working?
Is it a carrier specific device?
If yes are you using a sim card from that carrier?
Is the phone unlocked or factory unlocked or is it locked?
Was there any thing you did such as flashing custom roms?
I think it may have a bad Imei but I'm still trying to figure that out

dont know if you ever got your issue fixed or not, i had a similar problem the other day on my galaxy s4 i337
i was able to make phone calls and recieve text messages but i could not access the internet through the network, my carrier actually did something that helped but didnt fix it... the technical support team had me turn off the phone and then they erased me from the network, so when i turned the phone back on the phone rebuilt the network through the sim card and for some reason i have better reception now...
i still could not connect to the internet via wifi or mobile network so i factory wiped and installed the stock firmware.
do you have somewhere to go where they can "officially" flash the stock firmware? here in the usa i can take my phone to BestBuy, a large electronics dealer, and they have a samsung area that the people have the tools to do so.
maybe your network carrier can help you, maybe its not a phone issue but rather a network provider issue.

It's a little bit strange but you can try to use an adhesive tape on the side of sim card to prevent a short circuit between contacts and the sim card's metalic tray.
It worked for me.
Hey all! I have made the switch to a Nexus 6P about a year ago, so I am quite rusty with the S5 and how to do things with it. I recently sold an S5 on swappa, and I am attempting to help that user get it back to stock. I would have done this before selling, but we thought the process would have been more simple.
To quote the user I am assisting at the moment "... I crossed into canada a few days ago, phone worked good with international plan. cross back to US and keep getting weird "not registered on network" messages and have 0 connectivity to my Verizon phone network. Tried new sim card, verizon store says the issue is because it is rooted etc (doubt they know what they are talking about)....But figured i'd do a clean install etc and see what happens. Followed instructions for Odin. From what i read it sounds like I need the OA 8 Lollipop retail tar..phone model number is SM-G900V. Keep getting "NAND Write Start!! FAIL! (Auth)" in Odin. Tried multiple USB cables and other random tips I found online. Any advice? Am I using the wrong stock tar?"
What can I/we do to resolve this issue? I have searched xda, but I am totally lost with the S5 to be honest. Things have changed so much since I used the phone that I have no idea where to start. It was on Alliance ROM before I shipped it. It has the Toshiba eMMC (or whichever doesn't have bootloader unlock).
Again, thanks in advance guys!
Some more info about the phone, I'm the buyer.
Still running Alliance. I do have an IMEI # (some sites say that could be an issue).
Model/Phone name is Samsung Galaxy S5 SM-G900V
Baseband Version is G900VVRU2BOK3

Tue Nov 17 20:06:51 KST 2015

Exact message I get is "out of service area" when i make a call. then a "mobile network not available" message will pop up after.

Silly question, but have you tried pulling the battery, and Sim, let it sit for a sec, then power on to see if you have service? Might just need to reset the prl. Never been to Canada with the phone so idk what's going on ha.
Could also check the data settings to make sure it's set to CDMA+LTE instead of global or whatever other options it has. You haven't flashed a new radio file, have you? @miketon907

Pulled battery out and sim. No service fix. If I turn phone on with sim card out, it will say "no sim card". back sim card back in, no net work connection....It is set to CDMA+LTE. No, I have not flashed a radio file.

Ok, just trying to rule things out.
You activated the SIM in the US and used it before going to Canada, right?
Yep. so Sim card A which I got after buying the phone was working good. I went to Canada and used same sim card on international plan, went back to US and suddenly phone loses mobile connection and has no service as soon as I cross US border. went to Verizon for sim card B, sim card B does not work either.

You could try just doing a factory reset on recovery if you haven't already. Instead of starting from stock. Just wipe the data partition. If you wipe the system partition it won't have anything to boot into
oh. Well i'll try that later tonight. Report back around 11pm est. thanks!

Try flashing one of the modems on this page. It should reset the radio to have service again. I'd do it without the sim card in. Boot once, you obviously won't have service since there isn't a sim. Then turn off the device, insert the SIM and reboot.
I am looking into the write fail now just in case you can't even flash a modem file.
Also, you downloaded the samsung drivers, correct?
EDIT: I found an old thread that might help you troubleshoot odin - http://forums.androidcentral.com/sa...hacks/391849-galaxy-s5-odin-failing-root.html
EDIT 2: You might just have to switch to a different tar file. This user states that they used the same stock version as the one they were currently on. I'd give that a shot first. Then check to make sure "block reactivation" in security settings isn't checked. The exact directions that should get you going are from a user on that page, as follows;
"chainfire xda quote op-Follow these instructions to the letter. Do not touch any buttons or checkboxes that are not listed below to touch!
- Download and unzip the CF-Auto-Root-....zip file (see posts below this one)
- If you end up with a recovery.img and cache.img file, you've extracted twice. You need to end up with a .tar.md5 file - don't extract that one
- (USB) Disconnect your phone from your computer
- Start Odin3-vX.X.exe
- Click the PDA button, and select CF-Auto-Root-....tar.md5
- Put your phone in download mode (turn off phone, then hold VolDown+Home+Power to boot - if it asks you to press a button to continue, press the listed button, or run adb reboot download command)
- (USB) Connect the phone to your computer
- Make sure Repartition is NOT checked
- Click the Start button
- Wait for Android to boot
- Done (if it took you more than 30 seconds, you need practise!)
NOTE: Sometimes the device does *not* boot into recovery mode and root your device. Just do the entire procedure again if this happens. If it still will not install root and such, make sure that in Odin "Auto Reboot" is not checked. Then after flashing, pull the battery, and boot with VolUp+Home+Power button to boot into recovery manually. This will start the install process.
New to Samsung? Unfamiliar with Odin? Think all the above is a hassle? Get used to it. It's very simple, and us Samsung folk use Odin (or Mobile ODIN ) for everything! It's so very very convenient once you get used to it. Notice the 30 second comment above? For experienced users, the entire process indeed takes only 30 seconds!" - Dale Borrelli
Final note. Try the tar for the android version you are currently on first, then go up to the version you'd like to be on.
Edit: @miketon907 any luck yet?
yes, thanks a lot. flashing the modem worked. have service now again.
I moved my T-Mobile SIM card from my Nexus 6 to my never used, eBay purchase, 6p. The 6p does not detect the SIM card. I reinserted it multiple times with no luck. I don't know if it matters that I installed TWRP, Nitrogen ROM and Franco kernel, without the SIM in the phone?
The phone is otherwise fully functional.
Any ideas on what might be going wrong? The package slip that came with the 6p states, "Tested for Key Functions, Ready for Resale". I've contacted the seller for advice.

Probably should of checked it out before loading a custom ROM. That being said if the ROM is 8.0 I don't think the first version of the update is compatible with T-Mobile.
"8.0.0 (OPR6.170623.013, Aug 2017, Not for TMO/USCC/Fi)"
You should maybe try a stock ROM first. Get nexus root kit. There is an option to revert the phone back to stock. Might help.
Just a shot in the dark. May also be locked to a region. Good luck though.
I reinstalled stock Oreo. Now, I'm only seeing "No Service". I don't know if this is of significance, but when I check Settings - > System - > About phone - > Status, SIM status everything is blank. At least the SIM was detected. I didn't realize when I installed stock Oreo it would wipe out my SDcard.
The vendor image is used with Nitrogen was opr5.170623.007.img.
And I suppose the sim works in other phones?
It's hard to say what is going on. May just be in backwards?
Aside from the bootloop and battery issues the 6p has been awesome as far as loading ROMs. You never have to replace the bootloader so even if you break the recovery it can be fixed easily. Not the same for my sapphire unfortunately.
Anyways I would first say it may be a physical issue, Especially if the sim says it's blank. Again, good luck.
I believe it's just Android 8 and not the phone. Go through any 6p Oreo thread and will find one person with this problem. Solutions that where posted fingerprint/pincode security off before flashing, no encryption on first boot and solution that worked for me complete wipe of phone flashing stock Oreo. I haven't heard any direct answer on what the cause is and I think the first 2 solutions worked for people because they did a clean flash of stock Android 8 anyways.
Yes, the SIM works fine in my Nexus 6. I noticed under SIM status, it lists "No signal".
I installed the factory Nougat ROM and still no service.
Under SIM status in Settings, Network is Unknown, Signal strength is 0, Cellular network type is Unknown and Service state is Out of Service.

Yes, the SIM works fine in my Nexus 6. I noticed under SIM status, it lists "No signal". I installed the factory Nougat ROM and still no service. Under SIM status in Settings, Network is Unknown, Signal strength is 0, Cellular network type is Unknown and Service state is Out of Service.

Is your IMEI field blank too in Settings? If the phone does not have an IMEI, the device may have corrupted EFS partition(s). Boot the device to bootloader (fastboot mode) and select "Barcodes". Is your IMEI there? Is your model a H1511 (US model)?
Put a known working SIM in the phone from a different carrier (preferrably not an MVNO), If that doesn't work, since your phone is new (to you) there is no harm in fastboot formatting these 3 partitions (system, cache and userdata) and then using the Google script (batch file) that comes with a full factory image. Not a factory reset, not manually flashing a ROM. One other possible scenario is that if the phone was previously used on ProjectFi, you may need to contact Google and have your phone's IMEI de-registered. Hopefully you get it working and won't be forced to return the phone.

Barcodes shows IMEI present and model is H1511. I ran the script in the full factory image for Oreo and then tried the same with Nougat. I didn't reformat the partitions prior to flashing ROM. Is this important or does the factory image replace them anyways?
I don't have access to another carriers SIM card.

The script uses fastboot erase which does not format the partitions. Formatting returns partition information, any errors and in some cases corrections. You did not mention IMEI within settings, both under "SIM Status" and "IMEI information". If present in bootloader, but not in settings, this may further point to a SIM card. Until you try (borrow) another carrier's SIM for 5 minutes you won't know for sure. At the very least you could get TMo to provision you new SIM. They should not charge you for this, and it may change your situation. There are many threads on this very same topic. Maybe searching those would give you another idea.

According to Google, the phone was purchased from them. They do not know if the phone is financed, as this would cause the IMEI to be locked. I'll try the T-Mobile store next.
Spent an hour at T-Mobile. The sales rep was determined to fix it, but in the end was unsuccessful. The Ebay seller issued an RMA and I dropped off at the P.O.. Will try getting another.

No, I meant the the Google-Fi the MVNO (carrier) not finance. If the phone was activated on Fi, it will have to be de-registered on their end. You still did not reply about IMEI present or not in Settings>>Sim info?

When I went into Settings, the IMEI was present, but no carrier information. The phone recognized the SIM card, but that was all.
In the chat session with Google Support, I did ask about Google-Fi and she wrote that she was unable to provide any information on that. She said the only information she could provide is where the phone was purchased.
I came across the same issue. Just flash your vendor.img using flashfire, this will fix everything.
Another fix for the no sim is too turn off security pin lock and reboot the phone. I take no credit for this find just spreading the good word. ?

Thanks so much. Worked like a charm and could then reenable pin lock and reboot and SIM kept working.
