[Q] No signal/reception after rooting+flashing

Hi guys, I have a problem again.
I just flashed and rooted my phone yesterday, went OK, so now I have CM9 installed on my defy plus.
The only problem however is that I do not have any signal/reception. By that I mean that I can't make any calls or send text messages.
I tried adding APN's, tried basebandswitcher (a couple, don't know the correct one for Belgium).
And now I'm stuck
Could u guys help me with this? Cause a phone wich can't call isn't all that fun

The baseband for Belgium is the same as England and rest of Europe. Normally this is only the problem when 3g is not working. Try to flash again maybe...wipe data... Try disable/unable flymodus. Reboot a few times... Disable Simlock.

I agree with the previous poster, but it's almost certainly your baseband that is not set up properly. I live in Canada, and the baseband that works with my phone is China. Do some research, trial and error, and you'll get the right frequencies.

I have tried nearly all basebands, none worked.
Is there a way I can go back to stock ROM? I tried installing a new zip file to SD card, but my pc doesn't recognise my Defy anymore
I also didn't make any backups

FIXED
I installed a new ROM, Kernel and Google Apps (still CM9 --> Android 4.0)
Thanks for helping guys

[Q] Factory test and minor problem... any ideas???

Hi,
I'm sorry if i'm at the wrong place, but i'm kinda stuck...
This is my probleme : I got a SGH-t889V (with the candadian Carrier Videotron), yesterday was my first try to root and install a custom ROM (my mistake!)
I installed a ROM uncompatible with my device...the omega 6.1 (compatible with N7100 but bot with my device i think...), well what happened after that is that i lost my network, no cellular signal...no imei anymore...nothing, just stuck with a big mp3 player
I finally was able to got my network back...by flashing the modem and read a lots of post on this forum, i made a restore from my nandroid backup, but now, when i boot my cellphone, i Got the message "Factory test stop"...
I tried everything, flashed many times...format everything possible! but still...
I even tried a FULL format factory reset with the commande *XXXX*XXXX# and the message is still there...
I read that there is a command i can put in /efs/factoryapp/factorymode but it's not working... i still got the message.
It's not very a big problem in fact, cuz i got the network working but there are many things who don't like my alarm clock, the lock screen, the power button initially give me access to a menu to reboot, silence or shutdown, now it only shutdown the phone.
So anyone have an idea?
Thanks in advance
Alex

Did you try ODIN to stock firmware....there is a package for SGH-T889V

Problem on calling LG G3 F400k

Hi there developers. First of all sorry for my so bad bad ENGLISH.
So I have purchased a used LG G3 F400k Korean Variant with 3GB of RAM and 32GB ROM. When I first used the phone it runs stock lollipop and all seems working fine, not to mention it's Battery life and heating issue. Until then I got boring with its stock Rom, I rooted it and installed a Bumped TWRP via Flashify. The Flashify says I am installing a recovery that can replace my boot, but I still flashed it. It was succesful as it directly boot me into TWRP. Now when I tried to reboot it gives me an error boot like that and an infinite black screen with disco light led notification. I have no memory card yet and so I get my laptop and searched for its solution here on XDA. I flashed it using unofficial lg flash tool with 2 files such as ott and I forgot the other one. It was succesful an I reverted back to stock kitkat. And now the problem I faced is I CAN NO LONGER RECEIVE CALLS but I can make an outgoing call and it takes too long to ring when I am dialing and my network here has a menu when accessing *100# but it always failed and it gave me an invalid mme code or connection problem. I then flashed a twrp back and before I did that I have already downloaded the Fulmics Rom and flashed it through TWRP, thinking of the problem is by the rom itself. It was succesfull again. But then again my problem didn't solve by flashing another Rom.. And now I don't know what to do my imei is still here but still I have this problem. Would be appreciated if anyone would just reply to my thread and provide me some idea
Sorry I can't provide you screenshots coz I can't upload due to restrictions to a new members.

My Internet is so good. It's fast. Its LTE. I also turned off the VOLTE calling and Call forwarding or call rejecting. But still, my family is having problem contacting me because their call is directing to my Voice Mailbox. I tried putting my sim card in other phone and it's fine. I tried putting different SIM card to my phone and still facing the same issue. I think it's a hardware problem? Please help me.! I haven't tried bringing this to shop coz it's very expensive and thinking of someone could help me here instead. Please HELP!

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.
