My Xperia suddenly stopped connecting to mobile networks for some reason. The antennae is fine, it detects the networks but doesnt connect to them. I flashed the same rom and a couple of others to see what happens but the same problem persists. What should I do?
Try this
ONLY IF YOUR BOOTLOADER IS UNLOCKED flash another kernel and a rom , and reset all of your settings , if the problem is still there contact someone to repair your phone ... preferably sony.

Tried different kernels and roms, no luck...

its probably best to send your xperia for repairs , if not Try messing around with your GSM card or sim or what ever you want to call it, it may not be your phone

Hello Everyone
I have a very odd problem on my Xperia S device and this problem is not only limited to my device but is also for all other Xperia S devices that I have tried or used in my area!!!
The problem is related to the WiFi (the phone does not connect to any network and does not even detect any network)
after going back and forth with this problem I discovered that it is related to the GSM providers in my country Syria (both providers MTN or Syriatel) If I remove the SIM card everything works fine (My phone detects WiFi networks and is able to connect to any of them) so basically the problem is related to frequency matters (I guess).
I found one work around only: if I switch the WiFi off - reboot the phone - wait till the phone finishs booting and detecting the GSM network - then switch the WiFi on. This work around worked for me so far WiFi works completely fine after doing so even with the SIM card inserted but this only works for the official stock ROMs or modified ROMs based on the stock ones (If I try cyanogen based ROMs there is no way that I could find to make it work, I also tried the leaked official JB ROM 6.2.B.0.197 from DooMLoRD (BTW you are the best) and it did not work also whatever I try till I remove the SIM card and boot the phone without GSM.
Anyone can give me any hint or help about this annoying matter?? Thanks in advance.
PS: My phone is unlocked rooted and using stock 6.1.A.2.55 ROM with Advanced Stock Kernel v17
PS2: the problem as I said before exists in every Xperia S phone I tried is this area (whether are Lock or Unlocked, Rooted or NOT) and I tried about 7 or 8 devices so far, so it is not limited only to my device.

I did try and did not work + I tried it on several wireless routers same problem, that's why my guess it is related to frequency conflict between WiFi adapter and GSM SIM cards
anyways thanks for your help
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.

I don't know what problem the phone could have where you would be able to use Internet, but no calls or texts. I would call your service provider, and ask them to walk you through setup to activate service.
Besides that, the only things I would think would be to try different 'preferred network type' options in mobile settings, (maybe try 'global'), or flash new baseband. I always thought, though, that those things would also affect Internet, but maybe wrong...

Hi guys,
I've got a Mi Max 64gb, it was working ok and then it auto updated to MIUI 9 and now i get no signal. If I go into setting, it will show my sim name (three) but thats it. It has no signal and I thus can not make or take calls. The status bar at the top says no service.
I purchased the phone second hand and everything was working fine so did a blacklist check just in case and both IMEI come back clear. Also when I switch from fin network automatically to manual, it will find a few networks but will no connect.
Anyone know what can be wrong? Phone has locked bootloader fyi.

Ok so I got permission and unlocked the bootloader, installed TWRP and installed RESURRECTION REMIX 5.8.5 for hydrogen but its still showing no signal. Is there a way to check what can cause the problem as I've tried swapping sim trays (have a faulty one as spares).
Please show your holiday spirit and help me

I really have no idea what your problem might be, but the panacea in all weird cases, irrespective of the particular symptoms, seems to be to fastboot flash a official global stable rom with the Miflash tool.
Then you have hopefully a base "known state" to start from.
If you still have no signal, you might well have a hardware problem.

Hi,
I'm not any kind of expert at these kinds of (radio signal) problems today, though I do have a background in communications electronics construction (c.a. 1980's !)
If you did a complete format of everything before flashing the ROM, and it still doesn't work, I would guess you have a hardware problem.
Of course you want to double-check that your sim cards work in other phones.
I've had some rather weird problems caused by simcards.
You should even ask for a completely new simcard from some provider, and not put it into any other phone first.
How you could go about verifying that you truly have a hardware problem, without handing it over to a service center of some kind for testing, I really don't know.
Perhaps someone else has expertise in this area?
Otherwise, you just write it off as a loss, or sell it on Ebay for whatever you can get.
same with me. my phone not showing signal. the simcard is working before. it show no simcard after i flash twrp and supersu. the problem happen after restart phone. now i'm stuck searching this solution. help me.
Hi
So before anyone tells me to just insert a SIM and be done with it, please read this first. I'm trying to unlock the bootloader so I can try flashing different ROMs and radios. I had a perfectly working global version of the Redmi 7. After a phone call, the network went off and wouldn't return.
What I've tried so far:
•Trying multiple Sims known to work
•Manual network selection (fails because it can't find any)
•Changing preferred network modes and bands with the *#*#4636#*#* menu. Nothing happens.
•Toggling airplane mode, several times.
•Factory reset, both from within the OS and from the recovery (Vol Up + Power button)
•Attempting to flash a Fastboot version of the latest global MIUI 11 ROM. This actually fails, saying that critical partitions can't be flashed or something.
•All sorts of bootloader unlock tricks, such as the older versions of MiFlash Unlock, using multiple accounts, etc.
I'm honestly stuck here. Any help in fixing my problem would be appreciated. It could be either getting the network to work, or unlocking the bootloader. I can't bind the MiAccount to the phone under developer options ->MiUnlock status or such, because it detects that there is a SIM in the phone alright, but it just can't connect to any network.
The same here %
Was the SIM card's network working before? Maybe you're just in a dead spot?

It was working fine for a few months. It just stopped being able to connect to a network all of a sudden. I swapped SIMs, moved to places with strong network connections (I verified with a different phone) and still nothing.

Then you probably should head to a service center to get it fixed.

Same issue im having here but with a new POCO F2 pro. Since inception i was not able to get signal on it
I need to root my redmi 6a but bootloader makes a big trouble for me .for unlocking bootloader there must be sim in that device.but I doesn't have a sim card and even if I insert it, my sim board is damaged. So is there a way to unlock bootloader without inserting sim.
