Dual Sim Issue - Zuk Z1 Q&A, Help & Troubleshooting

I have jio in slot one and Airtel on two. I'm currently on RR and both Sims don't work together, I don't get internet in jio when I put 2 Sims, is there a solution or a romantic that supports this ?
PS. I tried ZUI and the prb was solved, but because of several bugs I had to revert back to ZUI

a bit confused, did you revert to zui because of bugs in which rom(cyanogen/lineage/nuclear)?
or did you revert from zui to other rom, because of bugs in zui

Any Custom ROM Supporting VoLTE ?

Hello All,
This query is regarding Redmi 2 Custom Rom. Is there any Custom ROM which supports VoLTE?
In India, Reliance Jio is launching 4G which will require VoLTE and hence this query. I have read that MIUI based on Lollipop base does support VoLTE but have not seen that option in Custom ROMs. Thanks in advance for help & comments
Edit
Basis feedback from users, to get VoLTE working following is solution:
1) One needs to first flash MIUI LP ROM (to get LP bootloader)
2) Second follow this by flashing ROMs like Orion, Mokee etc which supports VoLTE over LP bootloader
Read next post for details
Enable VoLTE in Redmi 2
The solution to get VoLTE working is following :
1) First, one needs to flash MIUI LP ROM (to get LP bootloader)
2) Second, flash ROMs like Orion, Mokee, RR, Project X, CM 13 etc which supports VoLTE over LP bootloader
3) Insert sim (example Jio for Indian users) and reboot. If required might have to create APN "ims"
4) In case APN "ims" doesn't work very well, pls follow this post here to replace apns config file.
That's it.. this will work.
Credits to multiple users from this thread. Cheers guys for being supportive

CM13 base Custom Roms does not support VoLTE
Im currently on Mokee with Jio sim & volte call does work. :good: I think cm13 too would work, Tesla didn't. Remember to be in lollipop firmware with volte support before flashing custom rom .

Can you try on DU latest build and confirm for me if it's working for you?
Cm-13
I am having a question.. When I'm using any custom rom and using my Jio 4G sim in any of the custom rom the performance isn't that great. For eg. If I'm getting 34mbps speed in MIUI then in any custom ROM i will be getting 0.5-1.0 Mbps speed. Can anyone tell me why is this happening and any workaround for it?

I tried d same..but calls nt wrkng..help bro
why install custom.. just install miui lollipop of redmi 2 prime and use VoLTE. it works
So in order to get VoLTE support on CM13, do you have to have Lollipop Bootloader and Modem flashed?
What about MM custom ROMs? Can anyone tell me for a fact if any ROM supports VoLTE. Also, can anyone confirm if this guide works for custom ROMs?
Can I Install the redmi 2 prime lollipop rom on redmi 2 1gb ram version are you sure it works, if not then what rom supports VoLte on 1gb redmi 2.
For me volte working perfectly
Cm 13, Zephyr, aicp, mokee

I read this somewhere in CM13 thread. Try these APN settings it should work
For volte go to network setting then select apn.
Add new apn with below details for volte
Name - jio
APN - ims
APN Type - ims
Rest of things you can keep as it is.
Also for 4g internet
Name - jio4g
APN - jionet
APN Type - default

I am using the zuk from 1 yr and it works fine with most of all marshmallow ROMs ( cm13, RR, dirty unicorn, nuclear) and it works fine....but when 1 st I installed nuclear N ROM .. During starter setup it asks for selecting sim for calls and data when we select it the selected sim for calls will not work and we can't change it afterwards also and if we call to that number we hear failed tone in another phone from which we call but we don't here in zuk. After that I restart phone removed sim and changed it worked after that. But now it is not working Selected sim will not work....sometimes we can't make calls from both the sim.... Please help...it is same with most of all nougat ROMs ( I have tried most of them all...)))
Thank u in advance...

It's a problem with the most of nougat roms..
Me too also faced same problem and i recommends you to try hexagon nougat custom rom ,it working fine.
Try the NucleaRom 7.1 beta. It's so stable for daily usage.

Official lineage os 14.1 calls switching problem

Hello hai to everyone..
Recently i flashed official lineage 14.1 os custom rom on my zuk z1 but I'm faced calling sim switch problem And i found that calls with option is disabled..Not able to enable it,I think it's a major bug...can anyone fixed please let me know.
I tried with both airtel Sims and as well as airtel and jio sims but problem is still unresolved only one sim is working to make a call even i though I'm using two airtel sims but not able to switch between them.
But I'm receiving messages as well from second sim only calls switching between sims is not working...first sim always enabled as the default sim to make a call.
I'm also unable to see the call screen while in a call therefore unable to hang up or dial numbers during a call. It simply does not appear at all (after selecting the person to dial it just rings them in the background)
I am also face this problem
I think this is one of the major issue every Zuk Z1 user is facing. Same here. Probably we should ask the users who has upgraded from CM 13 to LOS 14.1 and check even they are facing this dual sim bug or not...also I think flashing Zui will solve the problem, but is the image/zip file for Zui 2.5 (Android 7.0) is available anywhere?

Hexagon for Z1? I flashed the same on Yu Yuphoria and in the first boot, the boot logo kept on animating for half an hour, I gave up hope and flashed RR (Nougat). With Z1, any such issues did you face? And sim bug is gone or what because after LOS 14.1, I flashed RR 5.8.2 hoping the bug will go away, but that's not the case.?

sims working perfect and I haven't faced any problem but before flashing make sure that you have to wipe data,cache,system,boot folders.Take a backup before doing this process.
thank you.

I also have sim switching​ problem in my zuk z1 after installing Los 14.1.......
The call switching problem occurs since the baseband is not updated to correctly interact with Nougat. (As far as I know)
Flashing the ZUI zip corrects that since the modem is also updated, ZUI being an official software, and the company providing the updated modem files.
You can try updating the modem only, using fastboot commands in the bootloader with the modem file from ZUI zip and onto the modem partition.
Or you can wipe the device and do clean installs twice with ZUI, and LineageOS again.
Here's the link for ZUI 2.5 (Nougat) I used :

Try flashing NON-HLOS.bin from the zui zip using "fastboot flash modem *filename*" in bootloader mode.
**I haven't tried this so do take backup.**
And my problem was solved by clean flashing ZUI only. I used 2.5.115 beta version. I am currently using LineageOS, latest nightly from 4 April.

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..

Jio sim not working on custom roms

Hi..
I'm new here so please excuse if I asked noob questions:angel:
I have used LOS, AEX and PixelExperience ROMs and can't use JIO sims on any of them(no network). Other sims are working fine. I have searched threads and comments about this problem, but can't find any. Please refer if there are solutions for this or ...if there are custom roms with JIO sim working.
Thank you
Using aex here. Working perfectly in Chandigarh altough have some less network.
really?? then what could be the problem. I'm flashing stock ROM ..then Jio is working again... I'm from Mizoram.
