Hi,
I flashed 8T DDR4 now IN variant by 9R Full ROM OOS13. Everything worked fine except for one thing - no network signal on both SIM cards. Cards are detected but have no range at all. Is it a bands issue? Originally it is KB2003 EU version, now it has IN version software.
With 8T IN Rom everything works fine.
use dial code *#36446337# restore your nv and the imei and datas fixed i had issues and went into engineer mode restored my nv reboot and worked great
Hi.
Thanks for advice.
You mean this option?

Hi i have a nexus 5 (d 821) and i'm trying to get it work again. It has no signal with a valid sim card. i am in europe.
I tried cyanogenmod ( it shows usa, japan automatic ) but no signal.
i tried lineage the same thing.
I restore it in 6.0.1 google img ( it shows only usa band ) but no signal.
i restore in 4.4 ( it shows only usa band)but no signal.
Is this problem software or hardware?? is there any rom that can make my phone work again?
I searched through the forum and cannot find any clear solution for nexus 5
thank u
Was the phone ever dropped or dismantled and put back together?
It finds no networks at all?
Sim card works in another phone?
Tried other sim cards in the Nexus?
If this is a 2nd hand phone device and a problem with other sim cards too, I'd check if the IMEI has been blacklisted by a previous owner?
it has some falls , but i dont think this is the problem.
at *#4636 menu it shows only usa band (original nexus rom) and auto us japan band in lineage rom.
I think that the problem is in software with the radio img, or else with antenna or motherboad as hardware.
i need the opinion of an expert to deal the software part,
the sim cards works on other phones...
Is the model number d820 on the fastboot screen?

hey guys sorry to spam if this is being posted in incorrect section.
I live in UAE. I bought used american note 4 sm-n910p unlocked network. the person who sold me this phone already had it unlocked to use GSM sim. UAE sim used to work perfectly untill i flashed lineage rom to it. lineageos is awesome i loved it everything works fine but cannot get any sim to work in lineage. it always says no service. i tried dialing *#*#4636#*#* and changed to gsm only but that was resetting as soon as i reboot so i modified build.prop ro.radio.networkmode=3 to unable GSM on boot but that shows my network name and emergency calls only. i restored my previous backup rom in which GSM sim used to work but now after restoring sim doesn't work in backedup rom too and *#*#4636#*#* is not working in my backup rom :crying:
and if i reinstalling lineageos rom *#*#4636*#*# is not taking any effects
i flashed stock sm-n910p rom from sammobile that locked the network and shows "Hands Free Activation" so i reinstalled my backup rom. in this rom network bar shows but network always shows (searching)
Please Help:crying::crying:
BTW i cam across octoplus on youtube but soon realised it needs dongle or octoplus box to unlock sim. and saw some hacked videos it says octoplus can work without any box or dongle. Is This True or just haox to download their trojan virus?
I checked my IMEI on Visible's website and it checked out. I am running the Android 11 Pixel Experience ROM and Google Fi SIM worked fine, but I cannot get the Visible SIM to even be recognized as existing in the tray. I tried both SIM slots. Does this have something to do with being rooted? Ironically I installed this SIM in my Poco F3 which is NOT compatible, and although I got no service, that phone did recognize the SIM and even all of the Verizon APNs. Just wondering if you guys have any thoughts? Thanks.

It shouldnt have anything to do with being rooted, but if you have converted/changed firmware then that could be the issue.
If you have the engineering mode app installed u can check the sim in *#808# or by adb shell am start com.oneplus.factorymode/.manualtest.SimCardTest . If the test fails then the modem or your efs is messed up.Hopfully you have a efs back up. Try starting over with MSM flash first.I believe the fail sim is caused buy a key that is in the locked sfs folder of the efs. I do know for a fact there is a RSUprivate key there also. And have obtained it. But still have not found a way to write this back, other then efs restore in twrp.
I'm guessing it is related to the ROM.

I'm on visible and I'm using an unlocked T-Mobile gm1915. When on the global rom, it gave me a pop up to instructions for using the verizon sim on a cdma-less device. However, I didn't have to do anything and the sim started randomly working after waiting 5-10 minutes. So, i recommend just leaving the sim in for atleast 10 min and have mobile data on.
SOLVED!!!
(ANDROID 12?!)
PROBLEM: I have no network signal.
I successfully installed a custom rom but I noticed only one sim was working at a time which can't work for me. (not sure if that's a normal occurence for only one sim card to be working at a time.)
Used msm tool to go back to oos11 and now only one sim card is working and on the sim slot it says "no sim".
What should I do?
Solution:
After using MSM tool to downgrade from Android 12 to OOS 11, all I had to do was install the OTA available and both sims were up and running.
Same happened with me, after manual updating to oos 12 my only one sim is working but without internet signals and second sim IMEI is showing null but after downgrade to oos 11 both sims are working on my 8t.
Upgraded from pixel experience 11 to 13 and everything is working just fine other than the mobile data and SMS... sim is detected but there are no signals... IMEI number is showing but phone number sim name, network, and network type all are shown as unavailable
Sim working on other phones and was working on PE11 before as well... I also tried Pixel Experience 13 Plus and Lineage OS 20.0 but encountered the same issue on all 3 of them... using MSM tool works but reflashing rom causes the same issue again
