No sim card icon after updating to versions 3.6 and above of temasek CM12 build

Hello guys,
Ever since I updated to temasek's version 3.6 and later or the CM12 for the Note 3 LTE, I have lost the data connectivity as well the ability to make and receive phone calls since it is not detecting the sim card.
So far, all versions after 3.5 has resulted in the same behavior so I keep reverting back to version 3.5 since that is the latest version that allows my phone to work properly.
Does anyone know what could be the problem here?
Am i doing something wrong? Should i updated from one version to the next one or can i jump from say version 3.5 to version 5.4?
Thanks!

Modem issues

Hello, I have lost all simcard communication, no sms/call. I was first using rom: "[ROM] [6.0.1] Unofficial Paranoid Android - Jiayu S3". Everything was fine but I wanted to try out: "[ROM] [6.0.1] Unofficial AICP11 MM - Jiayu S3". This rom was a mess for me, no sms function and no calls. I tried to solve it myself by flashing a bunch of modem zips from the Jiayu S3 modem thread but nothing worked. I gave up and went back to the first rom that I mention and now nothing works as well on that rom.... So no sms sending receiving and no calls out/in. Do roms come with their own modem? If so what modem was the first rom that I mention packed with?

perhaps you lost imei?
try to Flash RC4 or RC5 with flash tools.
you can find on needrom.com
JiaYu S3, Nougat 7.1

OT wich backup app can be used with systemless root does anyone knows something it goes about normal apps that have no restore function for data ot end

the best rom

hi what is the best rom for zuk z2 pro?

AICP ROM oa CM froh Emmaus

and the mokee?

Is there a rom (pure or almost pure) that works well in zuk z2 with ota?

I'm waiting to get my phone and it's said it has Global rom. Is this rom good or should i change to other?

Sadly, stock room is the best as for now

You should probably flash another ROM. Either the stock one (which can be set to English but comes with A LOT of chinese apps and bloatware) or AICP / Mokee.
The "international" ROM that comes with your phones is most likely a modified ROM installed by the shop, which will be outdated, will not receive OTA updates, and might contain malwares. My Z2 came with a ROM on which the keyboard didn't even work at all, so I could not connect to the wifi, register my google account or anything untill I flashed a new ROM via USB.

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 :
https://forum.xda-developers.com/zuk-z1/orig-development/beta-zui-v2-5-115-t3539841
**It worked for me**

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.

Is anyone having good experience with MIUI 11? And has anyone downgraded back to 10?

So I was going to try and update to MIUI 11 but saw a lot of complaints of battery drain and more, and I was wondering, is anyone having a good experiance after the update or is this basically on every device? Mine phone is the European version, should install MIUI 11.0.2.0 PFJEUXM. Any reviews for this release?
Also, has anyone downgraded from 11 to 10 with no issues (rooted device with TWRP, not fastboot)? I've had issues when I downgraded from 10.3.12 to 10.3.7. The OS was installed but the device became unusable and I had to install 10.3.12 again
Thanks in advance

I own two MI 9T, one global and one EEU. Both are on MIUI 11 and I don't have any issues whatsoever. On the contrary, notifications now come in as they should. Apparently they fixed that.
Both phones are not modified (i.e. locked bootloader and unrooted). The only thing I did was to debloat it on user level (via ADB).
The battery drain happened just once months ago with MIUI 10. Never happened again... I'm pretty sure it was a rogue app or service.
And downgrading... I don't consider that (wait for unlocking bootloader flash TWRP etc.) and if I look at the forum I sometimes think that there are way to many help requests because of bricked phones

Thank you guys that was really helpful
I'm gonna try the weekly miuimix rom. I was wonder which twrp do you have though? Also, I'm aware that format data is required according to the instructions but just in case, is it possible to dirty flash it, or to restore data from nandroid backup of stock miui 10 after miuimix installation?
Thanks again

Alwayas the latest chinese TWRP

No trouble here (with Android 10 too). Battery drain does fluctuate though - some days I have 80 percent left in the evening, some days it's just 50 percent with no difference in usage. I also had days of heavy usage with 70 percent left shrug

Can you backup and restore on latest Chinese twrp? I currently have Team Win twrp (mauronofrio's) and I can backup but I get "extracttarfork() process ended with error=255" error when restoring. Is it the same on Chinese twrp?

I'm having bad idle time because of battery drain. But without that is really good update. Hope they fix the drain in coming updates.
