Hi guys, I have a problem with my RN2. It was working properly two months and today network just broke and after that always says no service. When I go into mobile networks it recognizes sim card, if I go to search mobile network sometime find networks, sometime not and newer want to connect. I was trying different sim card and always show same problem. I also tried several roms without results.
Anybody knows what the problem can be?
IMEI problem. Check this:

or you can copy IMEI from backup (if you have it)

I had the same problem like you. Phone show that service is sometimes working, sometimes not. But really iy never worked. I had to copy my IMEI from my backup and now everything works.
If you have backup, check if mobile service works on it.
Always throw this error...
Remove battery, put cable, press ok and back battery.
Also same problem, connect phone, remove battery press ok back battery.
I changed dll in system32...

Very strange.. I've had this phone for over 4 months and I was using the latest villain rom. Everything was working great and last night out of nowhere, the phone signal bars dissapeared and went into the no parking type singh that shows up instead. I didnt think much of it, I thought it was just my carrier (telcel, in mexico) sucking for a few minutes. After a while, nothing changed, I went into airplane mode and tried to go back to regular mode but the phone got stuck in airplane mode.
I erased all data, factory reset, even went back to telcel's stock rom. Reflashhd the original kernel, etc. Nothing.. basicaly, my galaxy s2 just became a mini tablet (because wifi does work)
If I go to settings and mobile networks it tells me the sim card isnt inserted. Which is not true. I still tried to switch to a different sim card to see if that was the problem but that didnt work either.
Is this a fixable problem? Or did my phone die?
Thanks
Looks like your efs partition is messed up. Hopefully you have a backup. There are many threads on here about efs problems.

Can you see your imei?

I don't have any kind of backups for that.. what do you mean?
as for the IMEI, dialing *#06# just shows a blank pop up that says IMEI but I get no number.
Any idea if this is fixable?

Hi,
I ran into this issue a few times and want to know if there anything I can do to solve it. I'm currently on Passion V13r1 with boot 2 kernel and I also did cleanup patch.
My phone service just went out for no reason. I can't call out or any calls can come in. I toggled the plane mode but that didn't help. Once I rebooted it then it come back ok. This has happened 3 times since I'm on V13r1. Anyone else run into this issue? Anything that I can do to solve this, pls advise.
I'm planning to flash V11b5 to see if it help with the speaker issue that I'm also having. Not sure if this will take care this problem too.
Thanks!

It sounds like your nvdata.bin got corrupted. Try and replace your nvdata.bin in your /efs folder with a known good backup.

Thanks for the advise but I went with MIUI for the time being. I still don't understand why it works most of the time if my nvdata.bin got corrupted. This problem happens only 3 times since I'm on Passion V3RC1 but not on V12.
I heard about similar issues on Passion FB page and I think it was a sim card problem. Try to get a replacement

A quick way to check to see if the problem is the phone's nvdata.bin, is to check the phones IMEI in System Settings > About Phone > Status. If the phone shows anything other than your IMEI, i.e. "unknown", then you most likely have a slightly corrupted nvdata.bin. The same thing happened to me a few times on 2.2 and when I first moved over to ICS. I replaced the SIM and was still getting the same errors while testing. Once I replaced the nvdata.bin in the /efs directory with a copy I made when I bought the phone, all the randomly losing network connectivity stopped. The biggest PITA about diagnosing the problem was it truly was happening randomly, with no discernible pattern at all.

Thanks for the info. I just checked and the IMEI has a valid number. I'm not sure if it is my number but it's a number, not unknown. So, it did again 1 time yesterday under MIUI rom.
Just to let you know, when this problem occurs and I tried to call out and it said that I'm on the airplane mode that I need to turn it off. But I check and I'm not on airplane mode. If I try to toggle the airplane mode, it toggled but sometime take a while to see the icon change from airplane mode to a normal service mode but still no service until reboot take place. On other hand, if someone call in, they don't get to the voicemail. The phone will hang up on 1st ring. As I notice, the problem seems to happen during sleep (screen is off)...
Do you think flash to different modem help in this case? I'm using Lithium MUIU rom and it has KB5 modem.
I've no signal anymore on my Galaxy S2. Ill do have Wifi and GPS, but can't find a provider.
So I tried to manually put in the provider information, but i doesn't remind/work.
After that I saw my IMEI number was gone and tried many things to recover it. But none worked for me
The stange thing is. That I have not flashed/factory reseted my mobile for some weeks. It suddenly happend.
I tried programs to write a IMEI number. But those programs didn't work. Maybe someone got a good working one or have other ideas?

I've been having some issues that i wasn't having before. I've got the OPX for about a month now and it is connected through LTE but i can't access internet.
If i turn airplane mode on and then off, it works for about a minute or so, then stops to work.
Anyone experiencing this?
Everything is ok here no problem yet

check apn's
APNs are there and they are well defined, I have manually redefined them now -> Airplane Mode on -> wait a few seconds -> Airplane mode Off -> surfed reddit for a minute or two, all of a sudden "This page cannot be displayed: 'ERR_TIMED_OUT' "
I would think this is a network problem, but there is a forum thread in oneplus forums where people are complaining about the same as me, although they associate the problem to Wifi and i don't
Also, i don't know if it's related, but I've flashed the latest version from MasterAwesome, the problems started there, i thought it was from the ROM, so i then flashed OOS2.1.3-x, where i had the same problem, then 2.1.2 and still the same issue...
I'm getting something like that issue but very rarely and mostly on WiFi. It comes between sleep and awake states so maybe check out greenify and see if that is the culprit. Or any other app that's restricting any function through the waking of the phone.
My oneplus x detects wifi very well, but does not connect to mobile data. What could be the problem?
Uh I have a similar issue but usually when I'm in motion. (in guessing switching between cell towers) what's your network. I'm using Tmobile US

Same problem I had yesterday. Must have tried 10 ROM's all of them flashed fine and everything worked except cellular data. I had no data what so ever. As soon as I flashed back to stock ROM data worked fine. So there must be a step or something we've missed in flashing custom ROM's spent all day yesterday trying to figure it out with no luck. Finally gave up and went back to stock. I'll wait for the official OTA marshmallow update from Oneplus
I'm having this issue right now with full 100% stock. Does any of you have the problem solved?
Just wiped data + cache + factory reset, but still no luck. I've also created a ticket on OnePlus support.

Are you using 2 SIMs? Data does not work for me on SIM 2 Slot but works fine on SIM 1.
I also can't connect to mobile data. There is no LATE/4G icon in the status bar but if I pull down the notification panel, LTE appears above the network icon. I've tried in both SIM slots. None of them work. The SIM card works fine on other phones.

Did you tried an other SIM? Change Sim location?
Did you reset APNs in the back up menu?

Yeah, I've tried 2 other working SIMs and I've deleted/resetted APNs, even manually configured them (copied from my other phone).
Maybe you lost the IMEI. Try to find it with *#*#4636*#*#

I have both IMEIs (dual-SIM) when I do *#06#
I flashed the stock rom and it's working! I will try it for a few days to see if it's a permanent fix.
Android N, same issue with all ROMs.. tried everything, no luck lte doesn't work at all.
Hi!
I did rooted my phone and unfortunatelly there is one problem...I lost my data connection. I have wifi and I can make calls but mobile data is just not working at all.
I have tried some methods...restart, sim out and back and restart, manually pick the provider and restart etc... nothing works.
I did not flashed any ROM but using stock so its wierd.
Any suggestion for a solution how to get back my mobile internet connection?
Thank you in advance,
Tom
I tried to changed APN manually to rogers but still data does not work, only call and text works. Is there a solution to this? I believe i got Pro 2 (cn with global rom installed)
I had the same issue, below is the APN setting on Rogers website, I've found that if you make the following changes, it will connect to 4G data (until you restart your device)APN Type: replace "internet + mms" with "*"
MVNO: ROGERS
MVNO type: SPN
This will get you connected.
However, I ran into another problem after configuring the network this way. After restarting the device, the phone can no longer detect the SIM card, and has an error message prompting restart).
This is my problem after restarting:
Comparing with other phones, the auto detected APN Type is typically "default", but entering default will cause the connection issue right away. The "*" will allow you to run until device reboot.
I too would like help on how to resolve this. Seems more software than hardware problem since it only fails after boot.

I just tried your method looks like it works and as you said it doesn't work after reboot. However when I did "Network setting reset," I was able to connect to 4g again (but resets wifi passwords too). Hopefully there's a solution...
I noticed that this problem only happens if there is a SAVED wifi network WHEN the device BOOT up.
I did a factory reset, then enter the APN manually. I was able to connect to stable network.
I did a system restart, no issue. The phone reconnects to the network automatically after booting.
I connect to a wifi network. The phone still works fine.
I restart the device again, the problem comes back.
If I take out the SIM and only use the Wifi, the phone is also okay.
The only time when it doesn't work is when I have both, which is the normal use case.
Something is happening in the firmware between the wifi and the SIM during the boot sequence.
This problem exists on my Lenovo L70081, Legion Phone Duel 2 Pro, running OS 12.5.188 ST, updated using Rescue and Smart Assistant v5.8.0.25
Any help would be appreciated.

Im on the same OS version 12.5.188ST, my phone connected to data absolutely fine with no problems but after every few hours stop making or receiving calls. I did the following and its fine for some time now but I'm not sure whether this will work with every phone but no harm in trying :
settings.....cellular network and sim.....5G mode. By default (at least in my phone) it is on NSA, I first switched to NSA+SA but to no avail, than I switched to SA and vola problem solved, all incoming outgoing calls working bang on but I think now my phone doesn't go on 5g which is still not good but at least making calls as normal. Now, as I said, this procedure might not work for everyone but try it, cheers.

Thanks for the suggestion, unfortunately setting the 5G setting didn’t help. I also tried disabling 5G but I still have the issue.
Was your OS able to read the APN from your SIM or did you have to enter the APN manually also?

There's currently two ROM available on Rescue and Smart Assistant:
L70081_ROW_SECURE_USER_Q00017.0_R_ROW_12.5.188_ST_210819_qpst
L70081_EE_SECURE_USER_Q00017.0_R_ROW_12.5.137_ST_210710_sec_qpst
What's the difference between ROW and EE rom?
Which would work best in Canada and US?
is ROW only updated in Asia and Pacific?
i sort of had this same problem with Tmobile. it would only connect to 3g . if i connected to the 4g or 5g network i lost everything . i was able to fix it using my ROOTED phone and an app in the playstore called network guru. I used that to turn off majority of the network bands and only left the ones listed for the phone. My service was immediately fixed and havent had any trouble since

I know how ya feel, I pestered TMobile for 2 weeks and they were no help. They kept trying to push me off to Lenovo who was absolutely no help at all. Id go thru their website which connects you to Motorola. Then they would tell me they don't support the phone because it's Lenovo and give me a link to follow. Id follow that link which led me right back to Motorola lmfao.
After 4-5 times of going thru that nonsense I finally got someone who knew what they were doing. They told me because this phone was never released in the US I need to go thru their European server for assistance. Screw that, I did some more research and got the idea of trying this from some ancient post I found on xda lol.
It's actually very easy as long as your phone is rooted. download the app, click the 3 dots and go into force control. Then adjust the carrier bands so only the ones supported by the phone are selected. Then reboot your phone and it should kick over to a working signal . If not ya might have to monkey around in the service menu using the dial code *#*#4636#*#*
Here's a few screenshots to give ya an idea and a link to a website with all the bands listed. https://www.kimovil.com/en/frequency-checker/US/lenovo-legion-2-pro
