Hello,
something very strange happening to my J7 2017 PRO, model (SM-J730GM/DS or J7y17lte) after I installed Crdroid 10.
Mobile cannot detect sim cards ! Help please.
I reverted to stock rom Pie Android 9.0 but same problem. What could have happened? Some EFS partitions deleted i read in some forums?
*How to restore telephony functions back ?
*Beside CrDroid, what other stable rom android 10/11 do you advice?

custom rom can't recognize sim card

hello every one
I updated my phone (xt 1572 dual sim) to android N official then I decided to install a custom rom
I installed a twrp recovery and rooted my phone. then I installed lineages 14.1 but the rom recognized only one simcard without any signal.
I have the same problem with other custom ROMs like lineages and resurrection
I tried to flash stock android MM but it didn't work.
what should i do now to have both sim cards on custom roms?
I really love lineage and Resurrection.
I'm waiting for your help.

Find a Rom that supports dual Sim cards, the ones that do will say so.

AICP . lineages and Resurrection all support dual sim card but in my phone they can't recognize simcard
i flash the stock MM 6.0.1 using fastboot and surprisingly my stock rom can't recognize simcards anymore, just like custom roms
what should i do?
is it because of system file changes?

It it solved my voLTE works now
Having a serious problem.....I'm running pixel experience ROM now but I have a tried nitrogen OS, ressurection remix ROM, Lineage OS 15.1, Viper OS (nougat), Lineage OS 14.1 and many other ROMs. Volte was working fine few days ago but for the past 3-4 days it was not working. I thought it was a problem with the ROM so I changed the ROM but still got the issue. And today I came to know that my device is showing IMS registration: unavailable
Voice-over LTE: not available and some other things
I tried messing with APNs and flashed some volte patches but still got no luck. Then I tried searching on XDA forum and know what I tried every possible method in almost all the threads and still not able to get volte. Tried searching YouTube for IMS registration and tried googling it also but still the problem is there.
Help me out plzzzz....

Maybe you need to write IMEI number again?
Does it show there when pressing *#06#* ?
U may try going back to MIUI 9
And then back to your favorite ROM
I did every single step mentioned above. Even my IMEI number is all good. But VOLTE problem reamins the same.
During the first boot...VOLTE was there, and it was working. Even when I Rebooted, it was again there and still working. But when I Power Off the device and then powered it on, VOLTE was gone and I was unable to call.

I did that too and thrice bt the problem remained unsolved. As I mentioned, it worked during the initial boot of any custom rom, even after rebooting it. Bt when I powered it off and then booted it up, VOLTE was gone.

Yeah happens with me to but now m using Xiaomi.eu miui 9 ROM bro use it for some days and flash another ROM voLTE will work fine as it creates a strong bond between firmware and ROM that miui 9 official doesn't and it has more features than it miui 9. So give it a try

Will Jio work?
Use this trick:-
Flash any miui rom v8 or v9 & boot into system..
Now go to recovery wipe all except storage.
Now flash any custom rom i suggest lineage 14.1 & boot into system..
Now again go to recovery go to wipe , advance wipe & wipe only system
Now flash any MIUI rom then wipe cache & dalvik
Now reboot...
Volla your volte now works...
I tried 2 times & all time it works....
If it works for u hit thanks..

No audio during calls

I unlocked the bootloader 2 weeks back. I have tried havoc os 2.9 3.3 rr pie lineage 17.1 miui by rinku, op5 port etc. I took the backup of all most every rom. I think I also made a couple of calls(call was working on havoc 2.9 previously). Yesterday while I was on havoc 2.9, I received a call. I attended the call. I was not able to hear any thing from the other side. The other side was unable to hear anything. Same with speaker also. Then reinstalled (fresh install, restoring backup fresh install without gapps also) havoc 2.9, 3.3, rr pie, lineage 17.1. but same result. But no problem with miui. And no problem with superior OS Q. I have searched xda and found certain foxes for gsi's and dolby patch for oreo. But my problem is not with gsi or oreo rom. Also tried making SElinux permissive. But no luck. I think the problem might have happened when I switched back to a pie rom from a Q rom. Does anybody have the same problem. Any solutions?

Is imei gone? If not gone try flash an AFT rom. If still not work you must backup persist, modem, qcn file and flash QFIL, restore qcn, persist, then up to 340. I helped a guy recovered his phone in that situation with this method.

Use an app named "PartitionsBackups" on play store. Go to the app's settings, choose backup type "RAW" then return, choose Persist, press backup button. Also use QFIL to backup QCN. I will help you if AFT rom don't work.

Navigate to /vendor/etc/acdbdata/QRD and delete QRD_Handset_cal.acdb. After doing this, you will NOT be able to control in-call volume(will always be at max) but this should fix your problem.
Though this should not break your phone, always have a backup of the file and set permissions to 0664(octal) while restoring.
I tried this quite a while back on havoc pie and it did work back then. You can still give this a go if everything else fails.
I also have same problem I m on pixel experience rom
Few days back I received an ota to update the rom
After claen flashing the latest build no audio from any speakers

broken sim card, after testing an android 12 gsi ..

Today I wanted to try a GSI of android 12 beta, and when I changed the rom I realized that there is no way for the sim cards to work anymore, I tried with several aosp rom, and even tried with the global rom and none solved the problem . Anyone who knows of any solution? Thank you so much.

OMG, this XDA app. When I want to post, it sometimes fails and pops-up totally useless "Broke the matrix... Neo..." and on next attempt it posts my message in double
Edit
Actually, you also posted the same twice, opening another thread for the same:
