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 was trying to force 3G in my OP2 and used *#*#4636#*#* to enter testing menu.
Under that menu, I accidentally selected some other radio band and now one sim( SIM 2) is disabled(unable to find network).
I tried resetting phone to factory setting, but it didn't helped.
Also updated to latest OxygenOS 2.2.1, still one sim is disabled.
Please help....

Flash OxygenOS Zip via Stock Recovery
---------- Post added at 09:37 AM ---------- Previous post was at 09:37 AM ----------
Before Flash Remember to Wipe All the Data
Hi,
My OnePlus 2 was running Exodus ROM, which had 2 Sim's: Vodafone (2G/3G) & other Jio (Only 4G/LTE).
I read a blog, that In order to increase the download speed from the Jio SIM, preferred LTE Band should be switched (from 3 to 40).
So, I pressed *#*#4636#*#*, >> Phone Info page >> three dot menu >> select radio band >> SELECTED Band mode 40.
Immediately after that,
Vodafone Sim stopped working in any of the SIM-Slots, But Jio sim (4G) was working in both the slots.
*****
Then I ran these commands in fastboot mode:
"fastboot erase modemst1 "
"fastboot erase modemst2 "
"fastboot erase cache"
Immediately, Both the SIM slots stopped working.
*****
Then I flashed "new-modem.zip" from benschhold (https://androidfilehost.com/?fid=24407100847293158)
which makes SIM-Slot-1 work with both Vodafone & Jio,
But SIM-Slot-2 only detects the sim, but with 0 network bars i.e. "No service| Vodafone"
*****
Clean flashed OOS 3.0.2 via TWRP, but SIM-Slot-2 = "No service| Vodafone".
I tried to manually search for networks,
It shows all the networks 2G & 3G in my city.
But connecting to Vodafone network from the list, always fails.
I think the latching (on to network) mechanism of SIM-slot 2, is faulty.
*****
Then clean flashed Exodus 29/8 build, but no fix.
Later, dirty flashed Exodus 31/8 build, which was supposed to flash the correct radio/modem/baseband on my OnePlus 2, but SIM-Slot-2, still doesn't let the SIM latch on to the network.
*****
Today, flashed "old-modem.zip" from benschhold, which resulted in phone stuck in boot loop.
Started OnePlus 2 Toolbox on PC, & flashed TWRP 2.8.7.0 via fastboot mode.
,successfully booted in TWRP 2.8.7.0 recovery.
flashed "new+modem.zip" (by benschhold).
Phone is working again, but SIM-Slot-2 = "No service| Vodafone".
@Spannaa @RajaMu @thegreatlex @Gonnelli1355
Will stock reset to OOS 3.0.2 from this link:
http://forum.xda-developers.com/showpost.php?p=62973446&postcount=2
fix this SIM-Slot-2 / EFS / Modem problem ?
Also, while stock reset, can this happen without formatting the internal storage ?
As I have 35+ GB of pics/music/data, which will take a lot of time to backup !

Stock Reset to OOS 3.0.2 might fix your issue but it will completely wipe your phone so you'll need to backup anything you want to keep first.
Not sure why you wiped your EFS partitions without taking a backup first...

Thanks for replying back.
I'm downloading your fastboot.zip file (1.13 GB) right now (does the zip file also contain all steps, to flash correctly ?).
You mentioned in that post, that we can add REM command in .bat file to avoid format to data partition, can this be done with internal storage too ?
Also, I don't know what is EFS partition, & did not knew I had to back it up, before flashing custom ROM.
Anyways, can you tell, out of all the steps I did.
Which step actually made the SIM-Slot-2, to behave in this way ?
Was it, the "erase modemst1 & modemst2" in fastboot ?
Or
flashing new or old modem zip of benschhold ?
As at first step, selecting the band 40, only made the Vodafone SIM not work, but the both the SIM-slots were still working fine with Jio sim.
& Erasing modem st1 & st2, made both SIM-Slots stopped working.
& flashing new-modem.zip, actually made SIM-slot-1 work again (with both Vodafone & Jio),
Then why did this not work with SIM-Slot-2 ?
Logically, whatever made SIM-Slot-1 work, should also work for SIM-Slot-2 too (with slight modifications) ?
Will flashing a good/proper modem.zip make the sim-slot-2 work again ?
Rather than me, wiping my phone to OOS ?
What do you think ?

I don't think the fastboot zip will solve your problem as it only contains the rom and firmware. I'm not sure that even the Stock Reset to OOS 3.0.2 tool will either but it's worth a go.
Erasing modemst1 & modemst2 with fastboot is what's caused your problem but I'm not sure how to solve it.

I don't think he can fix that.
EFS has the information about the IMEI of a phone as far as I know.
No IMEI = No signal
A dual SIM phone has two IMEIs, and that probably explains why one is working after restoring one EFS...

But I did not restore any EFS,
then how come IMEI 1, is working fine, even after erase command,
I checked IMEI 2 = 0.
& I checked a lot of OnePlus One forums. (OnePlus 2 has a lot less threads)
It's mentioned many times, that erasing modemst1 modemst2, does not erase the actual IMEI info from phone. (As it's stored in some other deep partitions).
Modemst1 modemst2, are supposed to rebuild themselves, after they are erased.
Correct me, if I'm wrong.

On some devices they're rebuilt from a backup in the fsg partition but it looks like this doesn't work properly for SIM2 on the OP2.
I see you've posted this in a couple of threads in the OP forums too! Good luck - there are very few people over there that know what they're talking about so be careful before trying anything that anyone suggests.

Hi @osr.arora,
Unfortunately I do not think the stock reset will help you with this issue (as those partitions are not at all touched by the OnePlus Stock Reset), however I would strongly suggest you to take a backup and reset the device as a starting point.
Do you have a nandroid backup of your device (all partitions)? Even if it is an old one, try restoring them.
Sorry but I am out of ideas for getting this sorted.

No, that's for the OnePlus One - you'll end up bricking your phone if you use tools built specifically for another device.

wrong radio band issue
Even I changed the band to band 40 however, I am getting the networks on both the Sim one being Jio and other being Vodafone. But the issue is I am not able to make calls from my vodafone number. There is no problem with incoming calls but out bound calls are not happening. JIO is working fine on both sim slots. Vodafone giving problem no matter if I switch the sim slots as well.
My lenovo vibe k5 note showing no imei. I did not rooted my mobile.
I don't know how it happened, but as I know I just changed the band of sim2 to band40 using mtk engineering mode.
Now there is no signal in both network.
Please help me. I bought this brand new mobile just before 10 days.

K5 Note cannot be rooted in Marshmallow(6.0) as of now because marshmallow rooting needs installation of custom recovery first, and no one has yet ported a custom recovery (TWRP CWM etc) for k5note. And porting custom recovery for k5note seems hard too cause the stock firmware has image check parameter, It doesn't flash just any customized image using SP Root tools.
However if you haven't updated it yet to marshmallow, It can be rooted when it is still in Android 5.1 Lollipop by using kingroot 4.50. , and then using Super Sume.

If you lost IMEI, Bluetooth Address, Wifi Mac address, Serial number , etc by flashing stock rom using SP flash tools, you can get everything back by following these two videos tutorial.
1st is for Rebuild IMEI and Barcode (PN).

2nd is for Rebuild Bluetooth, WiFi Mac Address and Serial Number (SN).

I LOST MY IMEI ON K5 NOTE(no backup)
Hi I purchased a Chinese Lenovo K5 Note (K52e78) but some of the features are only intended for Chinese and are written in Mandarin.
So I flashed the rom to 7020a48 6.0 marshmallow international version, And by doing this I have a vram error and also I have lost my imei.
The problem is I never got to back up my phone first windows shut down the sp tool program and bricked my phone.
I did manage to get my phone Flashed with the new 7020a78 software and It work's except for the problem I have with vram error(mac address) and no imei numbers.
Can someone please help me sort this problem out? As I only just bought the phablet a couple of days ago. And there is no one who has a clue in Australia how to fix it.

Hi I have same issue with my K4 note, will this method works in this mobile.
There is imei number written on your mobile phone bill, on battery and also on your mobile box. There are many app by which you can rewrite your imei number. But i think your imei number is not removed it just malfunctioning.
Try use this *#*#4636#*#* then phone information and here there is preferred network type you have changed band so your network operator type may have changed. Change it to wcdma or gsm.
Go to recovery mode and delete cache partition and then restart your mobile.
Here is how to change imei number.
For that you need to enter into engineering mode of your mobile.
Open engineering mode by dialing *#*#3646633#*#* or *#446633#. Also many apps available for entering mtk engineering mode you can download those apps from play store.
Once you are in engineering mode open Cds information. Then tap Radio information. Now if you have dual sim then you will see phone1 and phone2 otherwise just phone1.
Now tap on phone one and then enter command AT SPACE + EGMR=1,7 “ your first imei number” / AT +EGMR=1,7″your first imei number”. then tap on Send at command tab. and for second sim slot AT +EGMR=1,10″your second imei number”.
A few days I woke up with no service on the Nexus 6p. This was a few days after updating to the latest oreo build. Sim card seems detected because when I take it out another message shows up "No SIM card - No service", and when I put it back it only shows "No service". Tried putting the card in a Nexus 5X and it works fine.
Tried the following with nothing working so far:
- Switching 2G/3G/LTE and rebooting in between.
- *#*#4636#*#* and turning off the radio, switching between the different options of GSM/LTE/etc...
- Restoring a working nandroid backup
- Reflashing different ROMs
- Factory reset
- Factory reset then flashing ROMs
- Wiping cache and dalvik
- efs fix in twrp

IMEI shows up under IMEI information tab but not under SIM Status tab, there it shows not available.
I live in Ontario Canada, carrier is Freedom mobile.
So now I'm stuck, tried calling google and hwawei and they won't do an RMA because my warranty is expired.
Anyone has any ideas to try?
Thanks in advance.
Not that this is going to help, but this has GOT to be an Oreo issue, myself as well as at least 4 others that I have seen has been getting the No service, or No Sim, mine did the No Sim, then started bootlooping.

No this has nothing to do with O.
Which version phone do you have? H1511 or H1512?
What country are you in now?
What is your carrier? If MVNO state that.
Are your IMEI and phone numbers showing up in settings?
Everyone, please put the most basic information in your profile like where you live, which carrier you are currently on, and maybe even which variant of your phone.
I updated the first post with more info. How do I tell if I have H1511 or H1512? I bought it from the google store in Canada.
More information is good. Please update your XDA profile so the next person trying to help can check there first. You can find the device variant by booting to bootloader (not recovery) and using the vol toggle to navigate to "Barcodes". IMEI should show up there too. Date of manufacture, Serial #, etc. I think you should have started a normal thead, not Q/A, BUT your IMEI and a lot of other information should be showing up under SIM info. That's a problem. Second, you say you did the EFS fix in TWRP. Can you explain how you did this? Did you use one of YOUR OWN TWRP backups which contained the modemst1,modemst2 and restored ONLY those two partitions to your device? Did you receive any confirmation or error? Have you tried using a SIM from a Rogers or Telus in your phone to see if the SIM info shows up?
Thanks for the help, I'll update my profile with this info as well.
in the bootloader the IMEI shows up along with the rest of the info. It's a H1511 device.
The EFS fix is by following this: https://www.theandroidsoul.com/fix-empty-imei-corrupted-efs-no-sim-unknown-baseband-wifibluetooth-issues-restoring-twrp-backup/
is modemst1 and 2 contained in the twrp backup? and if so how do I restore it? in restore options there's system, data, vendor and boot only. I guess it's an option in the backup that I haven't selected?
I tried another SIM also from freedom and it didn't work. I don't have a Rogers or other SIM to try currently.
Right, so if you didn't ever select the EFS partitions when using TWRP Backup, you never backed them up so under Restore they don't show up (so you can't use that method). You can however use TWRP terminal or fastboot to wipe those and reboot. I would be sure to try at least one SIM from either Rogers or Telus. If that doesn't work, then wipe the EFS partitions and let them rebuild (hopefully).
Definitely Oreo issue. Google messed with something and it broke data for many people. I have been troubleshooting this for the last week (Verizon, US, fully stock 6P) and finally found a thread where a Google rep acknowledged the problem and said it was high priority for a fix.
I wish you luck with that one @LucJoe. This has been happening for the past 2 years from MM, N, and now O...and XDA is full of threads (just look). So you just go ahead and wait for Google to fix it for you, LOL. - Not a new issue related to O.
Never happened to me before updating. The data issues manifest differently across different carriers but for some reason Oreo likes to play it safe and disconnect data. I have not been able to get LTE for more than a couple seconds, but will get slow unstable 3G occasionally. Google confirmed the issue here: https://productforums.google.com/forum/#!msg/phone-by-google/kw3ZcXd1BVs/7HYuANdoAgAJ
A recent success using terminal from TWRP (or the OS if you are rooted). You can also use fastboot to do the same thing using the commands in the article posted in this Q/A (method 2). Good luck! See thread here.
This seems like it's a different issue described in that thread. I'm not running out of data, there's no service and no connection of at all to any network.
I did find that and try it before posting here. It did nothing to fix the problem. It did say that something was copied over '4 MB copied, at 14.3 MB/s' something like that but nothing changed.
I also have the same issue. Have tried everything including going back to stock 7.1.2 & locking the bootloader. Nothing seems to work. Interestingly, when i pull up the hidden phone diagnostic menu, it shows all cell measurement info which means that the antenna is receiving signals but the phone somehow is not registered on the network?
I can wipe those partitions with fastboot but is it safe? I have never used TWRP and my problems started after updating to Oreo. Is there a chance the official OTA could corrupt those partitions?
@LucJoe- That fix is not for you. That is for users who have no IMEI or phone number under About Phone>>SIM info. Your issue (as I understand it) is a weak and intermittent signal that keeps disconnecting LTE and sounds like a carrier or SIM issue. Why not go get a new SIM provisioned for your phone. That or pop somebody else's SIM in your phone and see if you get a different outcome.
Yes that was my first thought as well. I got a new SIM, then another one. So 3 SIMs now with the same result. I've been on the phone with so many techs from Verizon/Total Wireless and none of them have any answers. If I put the same SIMs into a Moto E4 I picked up for testing, it works fine. But the 6P immediately disconnects from LTE then bounces between 3G/1X.
My next test is to try a SIM from a different network I guess... maybe Verizon is blocking my 6P. Or maybe my LTE radio is damaged somehow.
So I did this using TWRP but wasn't sure if it actually went through or not. I did it now through adb from pc and also fastboot and it says permission denied. Any idea how to bypass that?
Got a tough one. Ever since last Wednesday my SIM card hasn't been recognizing like it should be. It will randomly stop working and not work again untill I flash a new rom/backup/stock. I've tried clearing the cache... Nothing. When I go into *#*#4636#*#*, if I turn of radio power, it will recognize my phone number after about 10 seconds. Also, It says that APN settings are not available for this user under APN settings... Any help is appreciated, thanks.

This only works with mediatek devices...
I have seen many posts about the sim card error, and have now experienced it myself. I have a USC XT1768 (on AT&T), running RR for about the last 4 months. Everything has worked perfectly until 3 nights ago when, suddenly, for no reason I had no service & saw there was "no sim" recognized. A Google search led me to switch to 3G and turn on airplane mode and reboot. After rebooting, I turned off airplane mode and service was restored. However, I am forced to use only 3G. After multiple "tests" switching back to 4G LTE, I always lose service. Yesterday, I "tested" again and LTE worked for about 8 hours before I got the sim card error. I re-did the airplane mode/3G process and I was back in business...just with 3G.
Last night when I got the "No Sim" error, I noticed that the preferred network in *#*#4636#*#* was "Unknown". It had been set to LTE/UMTS/Auto. It doesn't seem to make a difference if I switch it to Global, or anything else. The problem remains. Oddly, when I just entered *#*#4636#*#*, the preferred network setting was on WCDMA. Weird...I didn't select that setting.
Anyway, maybe this can kind of help someone else.
Tried the airplane mode/3g thing, still nothing for me. Just "lost" all recognition of a SIM. Nothing. No matter what I do, won't recognize. Lots online about it, loaded the latest F/W, etc., still nothing. The phone is like a new phone. Something feels hinkey about it though. Seems it's happening to unlocked Moto phones after about two-months.

I've had it for about a year when it happened, but what I did was send it to Moto and just told them it stopped working out of the blue. Flashed stock and sent it in. Within about 4 days they sent a new one. I would recommend that if you have a backup phone.
Did you have an unlocked bootloader (using the Moto code they send along with the warning that it'll void warranty)? If they still warrantied it, I'll do what you did, then sell the replacement ASAP. What an unreliable POS...

Not really. Clearly a small percentage of E4s have a SIM problem; Moto should own up to it. However, that's unlikely as they never acknowledged the HW GPS issue on the G4P line that impacts a much larger proportion of devices.

I think it's more related to custom modifications

Yeah, it was unlocked but I don't know why they had still look it though..
If you erase modemst1 and 2, the SIM will be recognized again. At least, it was on my XT1768. I wrote a small TWRP flashable version, for when it happens when I'm out and about. Just boot to recovery and "install" it. It's attached to my reply.
Additionally, the following firmware build is supposed to have the fix for this issue: https://androidfilehost.com/?fid=746010030569967659
Addendum: AFAIK, all Moto E4's running a build less than NPQ26.69-64 have the SIM issue. From what I've seen, it happens when one doesn't have any signal for a few hours, then comes back into an area that has a signal.

can you please explain this step by step for a naive person. My Moto E4 amazon version has same problem. Hoping to fix it on my own

Can you boot TWRP or another custom recovery? Need that to apply the 'fix' in the form presented. Not even sure it will work on a bootloader locked device.

Must be other variables involved. Have a much older build and frequently travel to/through areas with no coverage. Have yet to experience a SIM issue.

Your bootloader is locked, so you can't apply my fix from TWRP. You will need to hook up your phone to a computer, boot your phone to your bootloader (power + down), on your computer cd to your Android Sdk tools directory, then run "fastboot erase modemst1" and "fastboot erase modemst2", then reboot your phone.
However, you should be getting OTA updates. The most recent firmware should prevent the issue.
