Airplane mode on, network problem ZUK Z2

Hello, I'm having problem with my zuk z2. I've had phone for more than a month and it worked fine. I flashed mokee rom and was working excellent. After one update it couldn't connect to network and phone was stuck in airplane mode. It's not showing that airplane mode is on, only when I press power button it says it's on, but nothing happend when pressed. It detects both sim cards but can't get registered on network. Also in secret menu (*#*#4636#*#*) shows Radio off and can't turn it on, or change anything in that menu. I changed a lot of custom and stock roms, with locked and unlocked bootloader, nothing solved the problem. When flash fresh rom it has network (not after every flash), but after some times it just gets disconnected. Please, help me. If someone have solved this problem or have any idea what problem could be.
Edit: I found out that my sim slots IMEI change places, IMEI1 goes to slot 2.

i got the same problem

Same problem here with offician Indian ZUI

damn.. i thought this happened only with china rom.
didn't know it got same issue here.

Same problem

Same problem here. 2.0.133 ST official indian ROM. Any news about this problem?

I have the same issue running Slim 6 on zuk z2

i installed mokee os and the signal comeback again but actually not worked

Yes, I also installed mokee nightly 4/22 and its been working great. Signal is back

me too
Same problem Here.... bought on banggood and after one month network signal disappeared. Today I've unlocked the bootloader and installed Mokee stable ( 13-4-2017) and Lineage 14.1 of 16-01-2017 .... nothing! Still not working.
I suppose it is a failed lot from ZUK delivered from banggood/gearbest/ali ...
I've just wrote an email to zuk support in order to complain about it ...
Yes, because, right now I cannot send back in china at my expenses the equipment and pay for a substitution with another defective terminal.
I've just asked them hoto behave....
I suppose we need to start a class action like the one against samsung for S7 note
However, I'm very disappointed, 1 month and it was looking like a wonderful terminal ...fooooook.

Same problem here. Anybody please share the QCN backup (or valid link to download this) to try repair QCN and IMEIS ?

Same problem here:
I tested different roms and different baseband-versions still no network.
Edit: I also tried flashing it via an external tool - still does not work
http://www.androidbrick.com/zuk-z2-z2-pro-qpst-qfil-miflash-rom-flashing-guide/

I install the Z2plus_MIUI8_6.12.1_zukkati.zip ROM and recover the radios. I feel good!!!!!
Then I installed 2.5.334ST via Qfil, installed TWRP and install other ROMs and everything works fine.

Any Luck guys? Please help if anyone manage to resolve this issue.
Thank you!

Same with me
I had this problem also one month ago, bricked the phone and endly I could it get working again with lingeage on it. Was working perfect.
Today the problem is there again.
When I start the phone without the simcard airplane mode is off (when I touched the power button) with the simcard in the phone it starts with airplane mode on.
Is there a possibility to disable airplane mode complete?
Anyone any idea?

This problem has been around for ages, and no apparent solution to it. Sent it back to warranty and it got flashed frm Custom ROM and back to stock ROM with same results. Useless. Dead.
Got a partial refund instead .

Guys there is any solution?? I have this problem with my Zuk Z2.. Plz help me

Problem Solved
I also had same problem tried all methods described here and in zukfans.eu, but failed. At last discharging(shorting) some capacitor related to network IC did the job.

Moto z play with imei and without signal

How are you!
I hope that someone can help me with this, I had installed the Nougat version of January and everything had worked totally normal for 3 months, so yesterday I put the device in airplane mode for a couple of hours and when I removed it I have no signal. Then I decided to install the latest version of Nougat in this case with security patch March, and the problem is still the same, I do not have the problem that my IMEI has been deleted and besides that I start to be without signal with the equipment Fully functional, everything started when I put it in airplane mode.
Does anyone know it could have happened? My device is XT1635-02, my IMEI appears perfectly in IMEI information and in SIM status
Also I already probe with other SIM and neither is that, I have reinstalled three times the last Firmware of March the first time without the modem commands, and the last two times includes the modem commands and I continue without signal and obviously without loss of IMEI

A3 2017 Oreo battery life and incorrect CSC?

I've got a UK unbranded A3 2017 which after the official Oreo update had seriously ran out of Ram.
I installed the SamMobile BTU update using ODIN and added the adaptable storage mod and also encrypt bypass (but I didn't root the device)
First of all, the battery life is now atrocious, where it would easily last 2 days, I can barely get 12 hours from the device. Second of all and possibly related is I've got the issues with T-Roaming and KT twophone in settings (and three different battery settings!) which I believe is something to do with the CSC but I'm unsure how to fix it and if it will mean wiping the device again?

hows your cell standby ? i had the same issue and to me its was around 48% with 4g enabled and around 22% with 3g/2g network, but i had lost my imei too , flashing the original firmware the came with my device fixed it

Cell standby appears to be OK - and I've still got my IMEI. When you say original firmware that comes with the device, what files do you mean?

since your imei is there you dont need to worry about that , but i mean that files that you can download from sammobile

choose HOME_CSC FILE on odin. and yes, your device will ask to get wiped after bootanimation done, and there's no way to avoid it.

Sim not detecting

Hello Guys
With unlocked bootloader, I have been to China and used local sim over there.
Now I am back to India and none of Indian SIM cards are getting detected by phone.
I tried all possible options, did reset..downgraded to Oreo also..but no luck. What ever sim card I try, it's not getting detected.
In device info, it's showing mobile radio is off, tried switching on several times..but no luck.
Can someone pls help me ASAP.
Regards
Pavan

Try resetting network settings or hard reset the device and also try flashing factory image if previous doesn't work.
If your bootloader is locked then try reaching customer support. Else, you can try restoring some efs/modem backup using twrp.
Do you get any notification when you insert the sim tray?
I may be wrong just sharing my 2 cents.

Same problem here (or similar, at least).
My 5z recognized the SIM card on both slots, but no signal.
Tried all of the four carriers from Brazil, tried a hard reset, tried the Android Q beta, switched back to Pie, nothing works.
BTW, I've seen three devices with similar problems recently. One Samsung, and two Motorolas. All of them was updated to Pie. Could be some update bug?

My problem was fixed after the May update that was released a few days ago.
Everything working fine, 4G, LTE, etc.

Question No Network Connection (RIL Dead)

Hello everyone. I have a realme GT Master Edition (RMX3360).
The problem I am facing is that, SIM network does not work. SIM is recognised but it won't connect to any network, so basically I cannot use the SIM card even though the phone knows what SIM is this.
I did try:
Factory reset.
Use Force LTE app to access phone information and switch bands (I noticed radio toggle is switched off, I tried turning it on but it won't).
Unlock bootloader, just to increase my chances.
Flash only modem/hlos/... related partitions. Did not work (phone bricked).
Flash OFP firmware. Did not work.
Flash EDL firmware (C.09), which I am currently using. Still same problem.
Different SIM cards.
My IMEI is fine, it is recognised. My baseband version is 4. I did search for the issue in realme community, and it seems quite popular as a lot of people suffer from the same issue on different models.
I live in Sudan, we got no 5G, no VoLTE or whatever. Could you help me please?

I have similar problem after reboot .I can't connect to network or it tooks long time . What helps me is switching to airplane mode.

Switch to global rom maybe your sim card provider not supported switch to Rx3363

Thanks for the suggestion. I did install RMX3363 EU ROM from EDL, it booted fine but the phone still won't connect to any SIM network.
I will also try Russia ROM to see if it would make any difference.
Update:
I did flash Russian ROM from EDL, still does not work. Modem version is also still 4. I will try Chinese ROM next.

Try Latam version this what they put in middle east but so far i think its hardware issue did u try the sim card on another phone? Did you try another sim provider on your phone ? Sometimes if the sim card too old it wont work

That LATAM version is 18 Gigabytes haha. It'd take a few days to download.
I came to think it might be related to modem images as it showed the same version repeatedly on both RUI 2 & 3. So I'll try different modem images.
Also I'll try custom ROMs and GSIs. If it failed I'll return the device as a very last resort.
Update:
I tried latest Official ProjectElixir till date, still same problem.
Update 2:
I gave up the device and replaced it with another one under warranty. I will not buy another realme phone anytime soon.

I have a Xiaomi device too. The new virtual proximity sensor depends on hand movement to function. I don't use MIUI, but it is very fine at all situations.
Also I got a (256/8) GT Master replacement which is surprisingly working fine; being the same RMX3360.

It was already updated to F.03, I heard there was screen flickering or something but I didn't notice any so far.
But I did notice the battery was draining fast on mobile data. Really fast.
Besides, I can always lean on post-market development.

The general feel of the update is slower than the android 12 version
The battery will get better with you try to froze the app you dont use
